(b) Notwithstanding any other provision of the present Convention any certificate issued under, and in accordance with, the provisions of the International Convention for the Safety of Life at Sea, 1948, which is current when the present Convention comes into force in respect of the Administration by which the certificate is issued, shall remain valid until it expires under the terms of Regulation 13 of Chapter I of that Convention. (c) A Contracting Government shall not issue Certificates under, and in accordance with, the provisions of the International Convention for the Safety of Life at Sea, 1948 or 1929, after the date on which acceptance of the present Convention by the Government takes effect. Regulation 13 Issue of certificate by another Government A Contracting Government may, at the request of the Administration, cause a ship to be surveyed and, if satisfied that the requirements of the present Regulations are complied with, shall issue certificates to the ship in accordance with the present Regulations. Any certificate so issued must contain a statement to the effect that it has been issued at the request of the Government of the country in which the ship is or will be registered, and it shall have the same force and receive the same recognition as a certificate issued under Regulation 12 of this Chapter. Regulation 14 Duration of certificates (a) Certificates other than Cargo Ship Safety Construction Certificates, Cargo Ship Safety Equipment Certificates and Exemption Certificates shall be issued for a period of not more than 12 months. Cargo Ship Safety Equipment Certificates shall be issued for a period of not more than 24 months. Exemption Certificates shall not be valid for longer than the period of the certificates to which they refer. (b) If a survey takes place within two months before the end of the period for which a Cargo Ship Safety Radiotelegraphy Certificate or a Cargo Ship Safety Radiotelephony Certificate issued in respect of cargo ships of 300 tons gross tonnage and upwards, but less than 500 tons gross tonnage, was originally issued, that certificate may be withdrawn, and a new certificate may be issued which shall expire 12 months after the end of the said period. (c) If a ship at the time when its certificate expires is not in a port of the country in which it is registered, the certificate may be extended by the Administration, but such extension shall be granted only for the purpose of allowing the ship to complete its voyage to the country in which it is registered or is to be surveyed, and then only in cases where it appears proper and reasonable so to do. (d) No certificate shall be thus extended for a longer period than five months, and a ship to which such extension is granted shall not, on its arrival in the country in which it is registered or the port in which it is to be surveyed, be entitled by virtue of such extension to leave that port or country without having obtained a new certificate. (e) A certificate which has not been extended under the foregoing provisions of this Regulation may be extended by the Administration for a period of grace of up to one month from the date of expiry stated on it. Regulation 15 Form of certificates (a) All certificates shall be drawn up in the official language or languages of the country by which they are issued. (b) The form of the certificates shall be that of the models given in the Appendix to the present Regulations.

Regulation 16 Posting up of certificates All certificates or certified copies thereof issued under the present Regulations shall be posted up in a prominent and accessible place in the ship. Regulation 17 Acceptance of certificates Certificates issued under the authority of a Contracting Government shall be accepted by the other Contracting Governments for all purposes covered by the present Convention. They shall be regarded by the other Contracting Governments as having the same force as certificates issued by them. Regulation 18 Qualification of certificates (a) If in the course of a particular voyage a ship has on board a number of persons less than the total number stated in the Passenger Ship Safety Certificate and is in consequence, in accordance with the provisions of the present Regulations, free to carry a smaller number of lifeboats and other life-saving appliances than that stated in the Certificate, an annex may be issued by the Government, person, or organization referred to in Regulation 12 or 13. (b) This annex shall state that in the circumstances there is no infringement of the provisions of the present Regulations. It shall be annexed to the Certificate and shall be substituted for it in so far as the life-saving appliances are concerned. It shall be valid only for the particular voyage for which it is issued. Regulation 19 Control Every ship holding a certificate issued under Regulation 12 or Regulation 13 is subject in the ports of the other Contracting Governments to control by officers duly authorised by such Governments in so far as this control is directed towards verifying that there is on board a valid certificate. Such certificate shall be accepted unless there are clear grounds for believing that the condition of the ship or of its equipment does not correspond substantially with the particulars of that certificate. In that case, the officer carrying out the control shall take such steps as will ensure that the ship shall not sail until it can proceed to sea without danger to the passengers or the crew. In the event of this control giving rise to intervention of any kind, the officer carrying out the control shall inform the Consul of the country in which the ship is registered in writing forthwith of all the circumstances in which intervention was deemed to be necessary, and the facts shall be reported to the Organization. Regulation 20 Privileges The privileges of the present Convention may not be claimed in favour of any ship unless it holds appropriate valid certificates. PART C CASUALTIES Regulation 21 Casualties (a) Each Administration undertakes to conduct an investigation of any casualty occurring to any of its ships subject to the provisions of the present Convention when it judges that such an investigation may assist in determining what changes in the present Regulations might be desirable. (b) Each Contracting Government undertakes to supply the Organization with pertinent information concerning the findings of such investigations. No reports or recommendations of the Organization based upon such information shall disclose the identity or nationality of the ships concerned or in any manner fix or imply responsibility upon any ship or person. CHAPTER II CONSTRUCTION PART A GENERAL Regulation 1 Application (a) (i) Unless expressly provided otherwise, this Chapter applies to new ships. (ii) In the case of existing passenger ships and cargo ships the keels of which were laid on or after the date of coming into force of the International Convention for the Safety of Life at Sea, 1948, the Administration shall ensure that the requirements which were applied under Chapter II of that Convention to new ships as defined in that Chapter are complied with. In the case of existing passenger ships and cargo ships the keels of which were laid before the date of coming into force of that Convention, the Administration shall ensure that the requirements which were applied under Chapter II of that Convention to existing ships as defined in that Chapter are complied with. As regards those requirements of Chapter II of the present Convention which are not contained in Chapter II of the 1948 Convention the Administration shall decide which of these requirements shall be applied to existing ships as defined in the present Convention. (b) For the purpose of this Chapter: (i) A new passenger ship is a passenger ship the keel of which is laid on or after the date of coming into force of the present Convention, or a cargo ship which is converted to a passenger ship on or after that date, all other passenger ships being described as existing passenger ships. (ii) A new cargo ship is a cargo ship the keel of which is laid on or after the date of coming into force of the present Convention. (c) The Administration may, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of any specific requirements of this Chapter unreasonable or unnecessary, exempt from those requirements individual ships or classes of ships belonging to its country which, in the course of their voyage, do not proceed more than 20 miles from the nearest land. (d) In the case of a passenger ship which is permitted under paragraph (c) of Regulation 27 of Chapter III to carry a number of persons on board in excess of the lifeboat capacity provided, it shall comply with the special standards of subdivision set out in paragraph (e) of Regulation 5 of this Chapter, and the associated special provisions regarding permeability in paragraph (d) of Regulation 4 of this Chapter, unless the Administration is satisfied that, having regard to the nature and conditions of the voyage, compliance with the other provisions of the Regulations of this Chapter is sufficient. (e) In the case of passenger ships which are employed in the carriage of large numbers of unberthed passengers in special trades, such, for example, as the pilgrim trade, the Administration, if satisfied that it is impracticable to enforce compliance with the requirements of this Chapter, may exempt such ships, when they belong to its country, from those requirements on the following conditions: (i) That the fullest provision which the circumstances of the trade will permit shall be made in the matter of construction. (ii) That steps shall be taken to formulate general rules which shall be applicable to the particular circumstances of these trades. Such rules shall he formulated in concert with such other Contracting Governments, if any, as may be directly interested in the carriage of such passengers in such trades. Notwithstanding any provisions of the present Convention, the Simla Rules, 1931, shall continue in force as between the parties to those Rules until the rules formulated under sub-paragraph (e)(ii) of this Regulation shall come into force. Regulation 2 Definitions For the purpose of this Chapter, unless expressly provided otherwise: (a) (i) A subdivision loadline is a waterline used in determining the subdivision of the ship. (ii) The deepest subdivision loadline is the waterline which corresponds to the greatest draught permitted by the subdivision requirements which are applicable. (b) The length of the ship is the length measured between perpendiculars taken at the extremities of the deepest subdivision loadline. (c) The breadth of the ship is the extreme width from outside of frame to outside of frame at or below the deepest subdivision loadline. (d) The draught is the vertical distance from the moulded base line amidships to the subdivision loadline in question. (e) The bulkhead deck is the uppermost deck up to which the transverse watertight bulkheads are carried. (f) The margin line is a line drawn at least 3 inches (or 76 millimetres) below the upper surface of the bulkhead deck at side. (g) The permeability of a space is the percentage of that space which can be occupied by water. The volume of a space which extends above the margin line shall be measured only to the height of that line. (h) The machinery space is to be taken as extending from the moulded base line to the margin line and between the extreme main transverse watertight bulkheads bounding the spaces containing the main and auxiliary propelling machinery, boilers serving the needs of propulsion, and all permanent coal bunkers. In the case of unusual arrangements, the Administration may define the limits of the machinery spaces. (i) Passenger spaces are those which are provided for the accommodation and use of passengers, excluding baggage, store, provision and mail rooms. For the purposes of Regulations 4 and 5 of this Chapter, spaces provided below the margin line for the accommodation and use of the crew shall be regarded as passenger spaces. (j) In all cases volumes and areas shall be calculated to moulded lines. PART B SUBDIVISION AND STABILITY (Part B applies to passenger ships only, except that Regulation 19 also applies to cargo ships.) Regulation 3 Floodable length (a) The floodable length at any point of the length of a ship shall be determined by a method of calculation which takes into consideration the form, draught and other characteristics of the ship in question. (b) In a ship with a continuous bulkhead deck, the floodable length at a given point is the maximum portion of the length of the ship, having its centre at the point in question, which can be flooded under the definite assumptions set forth in Regulation 4 of this Chapter without the ship being submerged beyond the margin line. (c) (i) In the case of a ship not having a continuous bulkhead deck, the floodable length at any point may be determined to an assumed continuous margin line which at no point is less than 3 inches (or 76 millimetres) below the top of the deck (at side) to which the bulkheads concerned and the shell are carried watertight. (ii) Where a portion of an assumed margin line is appreciably below the deck to which bulkheads are carried, the Administration may permit a limited relaxation in the watertightness of those portions of the bulkheads which are above the margin line and immediately under the higher deck. Regulation 4 Permeability (a) The definite assumptions referred to in Regulation 3 of this Chapter relate to the permeabilities of the spaces below the margin line. In determining the floodable length, a uniform average permeability shall be used throughout the whole length of each of the following portions of the ship below the margin line: (i) the machinery space as defined in Regulation 2 of this Chapter; (ii) the portion forward of the machinery space; and (iii) the portion abaft the machinery space. (b) (i) The uniform average permeability throughout the machinery space shall be determined from the formula-
where: a = volume of the passenger spaces, as defined in Regulation 2 of this Chapter, which are situated below the margin line within the limits of the machinery space. c = volume of between deck spaces below the margin line within the limits of the machinery space which are appropriated to cargo, coal or stores. v = whole volume of the machinery space below the margin line. (ii) Where it is shown to the satisfaction of the Administration that the average permeability as determined by detailed calculation is less than that given by the formula, the detailed calculated value may be used. For the purpose of such calculation, the permeabilities of passenger spaces, as defined in Regulation 2 of this Chapter, shall be taken as 95, that of all cargo, coal and store spaces as 60, and that of double bottom, oil fuel and other tanks at such values as may be approved in each case. (c) Except as provided in paragraph (d) of this Regulation, the uniform average permeability throughout the portion of the ship before (or abaft) the machinery space shall be determined from the formula-
where: a = volume of the passenger spaces, as defined in Regulation 2 of this Chapter, which are situated below the margin line, before (or abaft) the machinery space, and v = whole volume of the portion of the ship below the margin line before (or abaft) the machinery space. (d) In the case of a ship which is permitted under paragraph (c) of Regulation 27 of Chapter III to carry a number of persons on board in excess of the lifeboat capacity provided, and is required under paragraph (d) of Regulation 1 of this Chapter to comply with special provisions, the uniform average permeability throughout the portion of the ship before (or abaft) the machinery space shall be determined from the formula-
where: b = the volume of the spaces below the margin line and above the tops of floors, inner bottom, or peak tanks, as the case may be, which are appropriated to and used as cargo spaces, coal or oil fuel bunkers, store rooms, baggage and mail rooms, chain lockers and fresh water tanks, before (or abaft) the machinery space; and v = whole volume of the portion of the ship below the margin line before (or abaft) the machinery space. In the case of ships engaged on services where the cargo holds are not generally occupied by any substantial quantities of cargo, no part of the cargo spaces is to be included in calculating "b". (e) In the case of unusual arrangements the Administration may allow, or require, a detailed calculation of average permeability for the portions before or abaft the machinery space. For the purpose of such calculation, the permeability of passenger spaces as defined in Regulation 2 of this Chapter shall be taken as 95, that of spaces containing machinery at 85, that of all cargo, coal and store spaces as 60, and that of double bottom, oil fuel and other tanks at such value as may be approved in each case. (f) Where a between deck compartment between two watertight transverse bulkheads contains any passenger or crew space, the whole of that compartment, less any space completely enclosed within permanent steel bulkheads and appropriated to other purposes, shall be regarded as passenger space. Where, however, the passenger or crew space in question is completely enclosed within permanent steel bulkheads, only the space so enclosed need be considered as passenger space. Regulation 5 Permissible length of compartments (a) Ships shall be as efficiently subdivided as is possible having regard to the nature of the service for which they are intended. The degree of subdivision shall vary with the length of the ship and with the service, in such manner that the highest degree of subdivision corresponds with the ships of greatest length, primarily engaged in the carriage of passengers. (b) Factor of subdivision - The maximum permissible length of a compartment having its centre at any point in the ship's length is obtained from the floodable length by multiplying the latter by an appropriate factor called the factor of subdivision. The factor of subdivision shall depend on the length of the ship, and for a given length shall vary according to the nature of the service for which the ship is intended. It shall decrease in a regular and continuous manner- (i) as the length of the ship increases, and (ii) from a factor A, applicable to ships primarily engaged in the carriage of cargo, to a factor B, applicable to ships primarily engaged in the carriage of passengers. The variations of the factors A and B shall be expressed by the following formulae (I) and (II) where L is the length of the ship as defined in Regulation 2 of this Chapter: L in feet
L in metres
L in feet B = 100 + .18 (L = 260 and upwards) L - 138 L in metres
(c) Criterion of service - For a ship of given length the appropriate factor of subdivision shall be determined by the Criterion of Service Numeral (hereinafter called the Criterion Numeral) as given by the following formulae (III) and (IV) where: Cs = the Criterion Numeral; L = length of the ship, as defined in Regulation 2 of this Chapter; M = the volume of the machinery space, as defined in Regulation 2 of this Chapter; with the addition thereto of the volume of any permanent oil fuel bunkers which may be situated above the inner bottom and before or abaft the machinery space; P = the whole volume of the passenger spaces below the margin line, as defined in Regulation 2 of this Chapter; V = the whole volume of the ship below the margin line; Pl = KN where: N = number of passengers for which the ship is to be certified, and K has the following values: Value of K Length in feet and volumes in cubic feet .6L Length in metres and volumes in cubic metres .056L Where the value of KN is greater than the sum of P and the whole volume of the actual passenger spaces above the margin line, the figure to be taken as Pl is that sum or 2/3 KN, whichever is the greater. When Pl is greater than P-
and in other cases-
For ships not having a continuous bulkhead deck the volumes are to be taken up to the actual margin lines used in determining the floodable lengths. (d) Rules for subdivision of ships other than those covered by paragraph (e) of this Regulation (i) The subdivision abaft the forepeak of ships 430 feet (or 131 metres) in length and upwards having a criterion numeral of 23 or less shall be governed by the factor A given by formula (I); of those having a criterion numeral of 123 or more by the factor B given by formula (II); and of those having a criterion numeral between 23 and 123 by the factor F obtained by linear interpolation between the factors A and B, using the formula: F = A - (A - B) (Cs - 23) ....................(V) 100 Nevertheless, where the criterion numeral is equal to 45 or more and simultaneously the computed factor of subdivision as given by formula (V) is .65 or less, but more than .50, the subdivision abaft the forepeak shall be governed by the factor .50. Where the factor F is less than .40 and it is shown to the satisfaction of the Administration to be impracticable to comply with the factor F in a machinery compartment of the ship, the subdivision of such compartment may be governed by an increased factor, which, however, shall not exceed .40. (ii) The subdivision abaft the forepeak of ships less than 430 feet (or 131 metres) but not less than 260 feet (or 79 metres) in length having a criterion numeral equal to S, where- S = shall be governed by the factor unity; of those having a criterion numeral of 123 or more by the factor B given by the formula (II); of those having a criterion numeral between S and 123 by the factor F obtained by linear interpolation between unity and the factor B using the formula:
(iii) The subdivision abaft the forepeak of ships less than 430 feet (or 131 metres) but not less than 260 feet (or 79 metres) in length and having a criterion numeral less than S, and of all ships less than 260 feet (or 79 metres) in length shall be governed by the factor unity, unless, in either case, it is shown to the satisfaction of the Administration to be impracticable to comply with this factor in any part of the ship, in which case the Administration may allow such relaxation as may appear to be justified, having regard to all the circumstances. (iv) The provisions of sub-paragraph (iii) of this paragraph shall apply also to ships of whatever length, which are to be certified to carry a number of passengers exceeding 12 but not exceeding:
(e) Special standards of subdivision for ships which are permitted under paragraph (c) of Regulation 27 of Chapter III to carry a number of persons on board in excess of the lifeboat capacity provided and are required under paragraph (d) of Regulation 1 of this Chapter to comply with special provisions. (i) (1) In the case of ships primarily engaged in the carriage of passengers, the subdivision abaft the forepeak shall be governed by a factor of .50 or by the factor determined according to paragraphs (c) and (d) of this Regulation, if less than .50. (2) In the case of such ships less than 300 feet (or 91.5 metres) in length, if the Administration is satisfied that compliance with such factor would be impracticable in a compartment, it may allow the length of that compartment to be governed by a higher factor provided the factor used is the lowest that is practicable and reasonable in the circumstances. (ii) Where, in the case of any ship whether less than 300 feet (or 91.5 metres) or not, the necessity of carrying appreciable quantities of cargo makes it impracticable to require the subdivision abaft the forepeak to be governed by a factor not exceeding .50, the standard of subdivision to be applied shall be determined in accordance with the following sub-paragraphs (1) to (5), subject to the condition that where the Administration is satisfied that insistence on strict compliance in any respect would be unreasonable, it may allow such alternative arrangement of the watertight bulkheads as appears to be justified on merits and will not diminish the general effectiveness of the subdivision. (1) The provisions of paragraph (c) of this Regulation relating to the criterion numeral shall apply with the exception that in calculating the value of Pl for berthed passengers K is to have the value defined in paragraph (c) of this Regulation or 125 cubic feet (or 3.55 cubic metres), whichever is the greater, and for unberthed passengers K is to have the value 125 cubic feet (or 3.55 cubic metres). (2) The factor B in paragraph (b) of this Regulation shall be replaced by the factor BB determined by the following formula: L in feet
L in metres
(3) The subdivision abaft the forepeak of ships 430 feet (or 131 metres) in length and upwards having a criterion numeral of 23 or less shall be governed by the factor A given by formula (I) in paragraph (b) of this Regulation; of those having a criterion numeral of 123 or more by the factor BB given by the formula in sub-paragraph (ii)(2) of this paragraph; and of those having a criterion numeral between 23 and 123 by the factor F obtained by linear interpolation between the factors A and BB, using the formula:
except that if the factor F so obtained is less than .50 the factor to be used shall be either .50 or the factor calculated according to the provisions of sub-paragraph (d)(i) of this Regulation, whichever is the smaller. (4) The subdivision abaft the forepeak of ships less than 430 feet (or 131 metres) but not less than 180 feet (or 55 metres) in length having a criterion numeral equal to Sl where-
shall be governed by the factor unity; of those having a criterion numeral of 123 or more by the factor BB given by the formula in sub-paragraph (ii)(2) of this paragraph; of those having a criterion numeral between Sl and 123 by the factor F obtained by linear interpolation between unity and the factor BB using the formula:
except that in either of the two latter cases if the factor so obtained is less than .50 the subdivision may be governed by a factor not exceeding .50. (5) The subdivision abaft the forepeak of ships less than 430 feet (or 131 metres) but not less than 180 feet (or 55 metres) in length and having a criterion numeral less than Sl and of all ships less than 180 feet (or 55 metres) in length shall be governed by the factor unity, unless it is shown to the satisfaction of the Administration to be impracticable to comply with this factor in particular compartments, in which event the Administration may allow such relaxations in respect of those compartments as appear to be justified, having regard to all the circumstances, provided that the aftermost compartment and as many as possible of the forward compartments (between the forepeak and the after end of the machinery space) shall be kept within the floodable length. Regulation 6 Special rules concerning subdivision (a) Where in a portion or portions of a ship the watertight bulkheads are carried to a higher deck than in the remainder of the ship and it is desired to take advantage of this higher extension of the bulkheads in calculating the floodable length, separate margin lines may be used for each such portion of the ship provided that: (i) the sides of the ship are extended throughout the ship's length to the deck corresponding to the upper margin line and all openings in the shell plating below this deck throughout the length of the ship are treated as being below a margin line, for the purposes of Regulation 14 of this Chapter; and (ii) the two compartments adjacent to the "step" in the bulkhead deck are each within the permissible length corresponding to their respective margin lines, and, in addition, their combined length does not exceed twice the permissible length based on the lower margin line. (b) (i) A compartment may exceed the permissible length determined by the rules of Regulation 5 of this Chapter provided the combined length of each pair of adjacent compartments to which the compartment in question is common does not exceed either the floodable length or twice the permissible length, whichever is the less. (ii) If one of the two adjacent compartments is situated inside the machinery space, and the second is situated outside the machinery space, and the average permeability of the portion of the ship in which the second is situated differs from that of the machinery space, the combined length of the two compartments shall be adjusted to the mean average permeability of the two portions of the ship in which the compartments are situated. (iii) Where the two adjacent compartments have different factors of subdivision, the combined length of the two compartments shall be determined proportionately. (c) In ships 330 feet (or 100 metres) in length and upwards, one of the main transverse bulkheads abaft the forepeak shall be fitted at a distance from forward perpendicular which is not greater than the permissible length. (d) A main transverse bulkhead may be recessed provided that all parts of the recess lie inboard of vertical surfaces on both sides of the ship, situated at a distance from the shell plating equal to one-fifth the breadth of the ship, as defined in Regulation 2 of this Chapter, and measured at right angles to the centre line at the level of the deepest subdivision loadline. Any part of a recess which lies outside these limits shall be dealt with as a step in accordance with paragraph (e) of this Regulation. (e) A main transverse bulkhead may be stepped provided that it meets one of the following conditions: (i) the combined length of the two compartments, separated by the bulkhead in question, does not exceed either 90 per cent of the floodable length or twice the permissible length, except that in ships having a factor of subdivision greater than .9, the combined length of the two compartments in question shall not exceed the permissible length; (ii) additional subdivision is provided in way of the step to maintain the same measure of safety as that secured by a plane bulkhead; (iii) the compartment over which the step extends does not exceed the permissible length corresponding to a margin line taken 3 inches (or 76 millimetres) below the step. (f) Where a main transverse bulkhead is recessed or stepped, an equivalent plane bulkhead shall be used in determining the subdivision. (g) If the distance between two adjacent main transverse bulkheads, or their equivalent plane bulkheads, or the distance between the transverse planes passing through the nearest stepped portions of the bulkheads, is less than 10 feet (or 3.05 metres) plus 3 per cent of the length of the ship, or 35 feet (or 10.67 metres) whichever is the less, only one of these bulkheads shall be regarded as forming part of the subdivision of the ship in accordance with the provisions of Regulation 5 of this Chapter. (h) Where a main transverse watertight compartment contains local subdivision and it can be shown to the satisfaction of the Administration that, after any assumed side damage extending over a length of 10 feet (or 3.05 metres) plus 3 per cent of the length of the ship, or 35 feet (or 10.67 metres) whichever is the less, the whole volume of the main compartment will not be flooded, a proportionate allowance may be made in the permissible length otherwise required for such compartment. In such a case the volume of effective buoyancy assumed on the undamaged side shall not be greater than that assumed on the damaged side. (i) Where the required factor of subdivision is .50 or less, the combined length of any two adjacent compartments shall not exceed the floodable length. Regulation 7 Stability of ships in damaged condition (a) Sufficient intact stability shall be provided in all service conditions so as to enable the ship to withstand the final stage of flooding of any one main compartment which is required to be within the floodable length. Where two adjacent main compartments are separated by a bulkhead which is stepped under the conditions of sub-paragraph (e)(i) of Regulation 6 of this Chapter the intact stability shall be adequate to withstand the flooding of those two adjacent main compartments. Where the required factor of subdivision is .50 or less but more than .33 intact stability shall be adequate to withstand the flooding of any two adjacent main compartments. Where the required factor of subdivision is .33 or less the intact stability shall be adequate to withstand the flooding of any three adjacent main compartments. (b) (i) The requirements of paragraph (a) of this Regulation shall be determined by calculations which are in accordance with paragraphs (c), (d) and (f) of this Regulation and which take into consideration the proportions and design characteristics of the ship and the arrangement and configuration of the damaged compartments. In making these calculations the ship is to be assumed in the worst anticipated service condition as regards stability. (ii) Where it is proposed to fit decks, inner skins or longitudinal bulkheads of sufficient tightness to seriously restrict the flow of water, the Administration shall be satisfied that proper consideration is given to such restrictions in the calculations. (iii) In cases where the Administration considers the range of stability in the damaged condition to be doubtful, it may require investigation thereof. (c) For the purpose of making damage stability calculations the volume and surface permeabilities shall be in general as follows: Spaces Permeability Appropriated to cargo, coal or stores 60 Occupied by accommodation 95 Occupied by machinery 85 Intended for liquids 0 or 95* * Whichever results in the more severe requirements. Higher surface permeabilities are to be assumed in respect of spaces which, in the vicinity of the damage waterplane, contain no substantial quantity of accommodation or machinery and spaces which are not generally occupied by any substantial quantity of cargo or stores. (d) Assumed extent of damage shall be as follows: (i) longitudinal extent: 10 feet (or 3.05 metres) plus 3 per cent of the length of the ship, or 35 feet (or 10.67 metres) whichever is the less. Where the required factor of subdivision is .33 or less the assumed longitudinal extent of damage shall be increased as necessary so as to include any two consecutive main transverse watertight bulkheads; (ii) transverse extent (measured inboard from the ship's side, at right angles to the centre line at the level of the deepest subdivision load line): a distance of one-fifth of the breadth of the ship, as defined in Regulation 2 of this Chapter; and (iii) vertical extent: from the base line upwards without limit. (iv) If any damage of lesser extent than that indicated in sub-paragraphs (i), (ii) and (iii) of this paragraph would result in a more severe condition regarding heel or loss of metacentric height, such damage shall be assumed in the calculations. (e) Unsymmetrical flooding is to be kept to a minimum consistent with efficient arrangements. Where it is necessary to correct large angles of heel, the means adopted shall, where practicable, be self-acting, but in any case where controls to cross-flooding fittings are provided they shall be operable from above the bulkhead deck. These fittings together with their controls as well as the maximum heel before equalisation shall be acceptable to the Administration. Where cross-flooding fittings are required the time for equalisation shall not exceed 15 minutes. Suitable information concerning the use of cross-flooding fittings shall be supplied to the master of the ship. (f) The final conditions of the ship after damage and, in the case of unsymmetrical flooding, after equalisation measures have been taken shall be as follows. (i) in the case of symmetrical flooding there shall be a positive residual metacentric height of at least 2 inches (or 0.05 metres) as calculated by the constant displacement method: (ii) in the case of unsymmetrical flooding the total heel shall not exceed seven degrees, except that, in special cases, the Administration may allow additional heel due to the unsymmetrical moment, but in no case shall the final heel exceed fifteen degrees; (iii) in no case shall the margin line be submerged in the final stage of flooding. If it is considered that the margin line may become submerged during an intermediate stage of flooding, the Administration may require such investigations and arrangements as it considers necessary for the safety of the ship. (g) The master of the ship shall be supplied with the data necessary to maintain sufficient intact stability under service conditions to enable the ship to withstand the critical damage. In the case of ships requiring cross-flooding the master of the ship shall be informed of the conditions of stability on which the calculations of heel are based and be warned that excessive heeling might result should the ship sustain damage when in a less favourable condition. (h) (i) No relaxation from the requirements for damage stability may be considered by the Administration unless it is shown that the intact metacentric height in any service condition necessary to meet these requirements is excessive for the service intended. (ii) Relaxations from the requirements for damage stability shall be permitted only in exceptional cases and subject to the condition that the Administration is to be satisfied that the proportions, arrangements and other characteristics of the ship are the most favourable to stability after damage which can practically and reasonably be adopted in the particular circumstances. Regulation 8 Ballasting When ballasting with water is necessary, the water ballast should not in general be carried in tanks intended for oil fuel. In ships in which it is not practicable to avoid putting water in oil fuel tanks, oily-water separator equipment to the satisfaction of the Administration shall be fitted, or other alternative means acceptable to the Administration shall be provided for disposing of the oily-water ballast. Regulation 9 Peak and machinery space bulkheads, shaft tunnels, &c. (a) (i) A ship shall have a forepeak or collision bulkhead, which shall be watertight up to the bulkhead deck. This bulkhead shall be fitted not less than 5 per cent of the length of the ship, and not more than 10 feet (or 3.05 metres) plus 5 per cent of the length of the ship from the forward perpendicular. (ii) If the ship has a long forward superstructure, the forepeak bulkhead shall be extended weathertight to the deck next above the bulkhead deck. The extension need not be fitted directly over the bulkhead below, provided it is at least 5 per cent of the length of the ship from the forward perpendicular, and the part of the bulkhead deck which forms the step is made effectively weathertight. (b) An afterpeak bulkhead, and bulkheads dividing the machinery space, as defined in Regulation 2 of this Chapter, from the cargo and passenger spaces forward and aft, shall also be fitted and made watertight up to the bulkhead deck. The afterpeak bulkhead may, however, be stopped below the bulkhead deck, provided the degree of safety of the ship as regards subdivision is not thereby diminished. (c) In all cases stern tubes shall be enclosed in watertight spaces of moderate volume. The stern gland shall be situated in a watertight shaft tunnel or other watertight space separate from the stern tube compartment and of such volume that, if flooded by leakage through the stern gland, the margin line will not be submerged. Regulation 10 Double bottoms (a) A double bottom shall be fitted extending from the forepeak bulkhead to the afterpeak bulkhead as far as this is practicable and compatible with the design and proper working of the ship. (i) In ships 165 feet (or 50 metres) and under 200 feet (or 61 metres) in length a double bottom shall be fitted at least from the machinery space to the forepeak bulkhead, or as near thereto as practicable. (ii) In ships 200 feet (or 61 metres) and under 249 feet (or 76 metres) in length a double bottom shall be fitted at least outside the machinery space, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable. (iii) In ships 249 feet (or 76 metres) in length and upwards a double bottom shall be fitted amidships, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable. (b) Where a double bottom is required to be fitted its depth shall be to the satisfaction of the Administration and the inner bottom shall be continued out to the ship's sides in such a manner as to protect the bottom to the turn of the bilge. Such protection will be deemed satisfactory if the line of intersection of the outer edge of the margin plate with the bilge plating is not lower at any part than a horizontal plane passing through the point of intersection with the frame line amidships of a transverse diagonal line inclined at 25 degrees to the base line and cutting it at a point one-half the ship's moulded breadth from the middle line. (c) Small wells constructed in the double bottom in connection with drainage arrangements of holds, &c., shall not extend downwards more than necessary. The depth of the well shall in no case be more than the depth less 18 inches (or 457 millimetres) of the double bottom at the centreline, nor shall the well extend below the horizontal plane referred to in paragraph (b) of this Regulation. A well extending to the outer bottom is, however, permitted at the after end of the shaft tunnel of screw ships. Other wells (eg, for lubricating oil under main engines) may be permitted by the Administration if satisfied that the arrangements give protection equivalent to that afforded by a double bottom complying with this Regulation. (d) A double bottom need not be fitted in way of watertight compartments of moderate size used exclusively for the carriage of liquids, provided the safety of the ship, in the event of bottom or side damage, is not, in the opinion of the Administration, thereby impaired. (e) In the case of ships to which the provisions of paragraph (d) of Regulation 1 of this Chapter apply and which are engaged on regular service within the limits of a short international voyage as defined in Regulation 2 of Chapter III, the Administration may permit a double bottom to be dispensed with in any part of the ship which is subdivided by a factor not exceeding .50, if satisfied that the fitting of a double bottom in that part would not be compatible with the design and proper working of the ship. Regulation 11 Assigning, marking and recording of subdivision loadlines (a) In order that the required degree of subdivision shall be maintained, a loadline corresponding to the approved subdivision draught shall be assigned and marked on the ship's sides. A ship having spaces which are specially adapted for the accommodation of passengers and the carriage of cargo alternatively may, if the owners desire, have one or more additional loadlines assigned and marked to correspond with the subdivision draughts which the Administration may approve for the alternative service conditions. (b) The subdivision loadlines assigned and marked shall be recorded in the Passenger Ship Safety Certificate, and shall be distinguished by the notation C.l for the principal passenger condition, and C.2, C.3, &c., for the alternative conditions. (c) The freeboard corresponding to each of these loadlines shall be measured at the same position and from the same deck line as the freeboards determined in accordance with the International Convention respecting Load Lines in force. (d) The freeboard corresponding to each approved subdivision loadline and the conditions of service for which it is approved, shall be clearly indicated on the Passenger Ship Safety Certificate. (e) In no case shall any subdivision loadline mark be placed above the deepest loadline in salt water as determined by the strength of the ship and/or the International Convention respecting Load Lines in force. (f) Whatever may be the position of the subdivision loadline marks, a ship shall in no case be loaded so as to submerge the loadline mark appropriate to the season and locality as determined in accordance with the International Convention respecting Load Lines in force. (g) A ship shall in no case be so loaded that when she is in salt water the subdivision loadline mark appropriate to the particular voyage and condition of service is submerged. Regulation 12 Construction and initial testing of watertight bulkheads, &c. (a) Each watertight subdivision bulkhead, whether transverse or longitudinal, shall be constructed in such a manner that it shall be capable of supporting, with a proper margin of resistance, the pressure due to the maximum head of water which it might have to sustain in the event of damage to the ship but at least the pressure due to a head of water up to the margin line. The construction of these bulkheads shall be to the satisfaction of the Administration. (b) (i) Steps and recesses in bulkheads shall be watertight and as strong as the bulkhead at the place where each occurs. (ii) Where frames or beams pass through a watertight deck or bulkhead, such deck or bulkhead shall be made structurally watertight without the use of wood or cement. (c) Testing main compartments by filling them with water is not compulsory. When testing by filling with water is not carried out, a hose test is compulsory; this test shall be carried out in the most advanced stage of the fitting out of the ship. In any case, a thorough inspection of the watertight bulkheads shall be carried out. (d) The forepeak, double bottoms (including duct keels) and inner skins shall be tested with water to a head corresponding to the requirements of paragraph (a) of this Regulation. (e) Tanks which are intended to hold liquids, and which form part of the subdivision of the ship, shall be tested for tightness with water to a head up to the deepest subdivision loadline or to a head corresponding to two-thirds of the depth from the top of keel to the margin line in way of the tanks, whichever is the greater; provided that in no case shall the test head be less than 3 feet (or 0.92 metres) above the top of the tank. (f) The tests referred to in paragraphs (d) and (e) of this Regulation are for the purpose of ensuring that the subdivision structural arrangements are watertight and are not to be regarded as a test of the fitness of any compartment for the storage of oil fuel or for other special purposes for which a test of a superior character may be required depending on the height to which the liquid has access in the tank or its connections. Regulation 13 Openings in watertight bulkheads (a) The number of openings in watertight bulkheads shall be reduced to the minimum compatible with the design and proper working of the ship; satisfactory means shall be provided for closing these openings. (b) (i) Where pipes, scuppers, electric cables, &c., are carried through watertight subdivision bulkheads, arrangements shall be made to ensure the integrity of the watertightness of the bulkheads. (ii) Valves and cocks not forming part of a piping system shall not be permitted in watertight subdivision bulkheads. (iii) Lead or other heat sensitive materials shall not be used in systems which penetrate watertight subdivision bulkheads, where deterioration of such systems in the event of fire would impair the watertight integrity of the bulkheads. (c) (i) No doors, manholes, or access openings are permitted: (1) in the collision bulkhead below the margin line; (2) in watertight transverse bulkheads dividing a cargo space from an adjoining cargo space or from a permanent or reserve bunker, except as provided in paragraph (l) of this Regulation. (ii) Except as provided in sub-paragraph (iii) of this paragraph, the collision bulkhead may be pierced below the margin line by not more than one pipe for dealing with fluid in the forepeak tank, provided that the pipe is fitted with a screwdown valve capable of being operated from above the bulkhead deck, the valve chest being secured inside the forepeak to the collision bulkhead. (iii) If the forepeak is divided to hold two different kinds of liquids the Administration may allow the collision bulkhead to be pierced below the margin line by two pipes, each of which is fitted as required by sub-paragraph (ii) of this paragraph, provided the Administration is satisfied that there is no practical alternative to the fitting of such a second pipe and that, having regard to the additional subdivision provided in the forepeak, the safety of the ship is maintained. (d) (i) Watertight doors fitted in bulkheads between permanent and reserve bunkers shall be always accessible, except as provided in sub-paragraph (ii) of paragraph (k) of this Regulation for between deck bunker doors. (ii) Satisfactory arrangements shall be made by means of screens or otherwise to prevent the coal from interfering with the closing of watertight bunker doors. (e) Within spaces containing the main and auxiliary propelling machinery including boilers serving the needs of propulsion and all permanent bunkers, not more than one door apart from the doors to bunkers and shaft tunnels may be fitted in each main transverse bulkhead. Where two or more shafts are fitted the tunnels shall be connected by an inter-communicating passage. There shall be only one door between the machinery space and the tunnel spaces where two shafts are fitted and only two doors where there are more than two shafts. All these doors shall be of the sliding type and shall be located so as to have their sills as high as practicable. The hand gear for operating these doors from above the bulkhead deck shall be situated outside the spaces containing the machinery if this is consistent with a satisfactory arrangement of the necessary gearing. (f) (i) Watertight doors shall be sliding doors or hinged doors or doors of an equivalent type. Plate doors secured only by bolts and doors required to be closed by dropping or by the action of a dropping weight are not permitted. (ii) Sliding doors may be either: hand operated only, or power operated as well as hand operated. (iii) Authorized watertight doors may therefore be divided into three Classes: Class 1 - hinged doors; Class 2 - hand operated sliding doors; Class 3 - sliding doors which are power operated as well as hand operated. (iv) The means of operation of any watertight door whether power operated or not shall be capable of closing the door with the ship listed to 15 degrees either way. (v) In all classes of watertight doors indicators shall be fitted which show, at all operating stations from which the doors are not visible, whether the doors are open or closed. If any of the watertight doors, of whatever Class, is not fitted so as to enable it to be closed from a central control station, it shall be provided with a mechanical, electrical, telephonic, or any other suitable direct means of communication, enabling the officer of the watch promptly to contact the person who is responsible for closing the door in question, under previous orders. (g) Hinged doors (Class 1) shall be fitted with quick action closing devices, such as catches, workable from each side of the bulkhead. (h) Hand operated sliding doors (Class 2) may have a horizontal or vertical motion. It shall be possible to operate the mechanism at the door itself from either side, and in addition, from an accessible position above the bulkhead deck, with an all round crank motion, or some other movement providing the same guarantee of safety and of an approved type. Departures from the requirement of operation on both sides may be allowed, if this requirement is impossible owing to the layout of the spaces. When operating a hand gear the time necessary for the complete closure of the door with the vessel upright, shall not exceed 90 seconds. (i) (i) Power operated sliding doors (Class 3) may have a vertical or horizontal motion. If a door is required to be power operated from a central control, the gearing shall be so arranged that the door can be operated by power also at the door itself from both sides. The arrangement shall be such that the door will close automatically if opened by local control after being closed from the central control, and also such that any door can be kept closed by local systems which will prevent the door from being opened from the upper control. Local control handles in connection with the power gear shall be provided each side of the bulkhead and shall be so arranged as to enable persons passing through the doorway to hold both handles in the open position without being able to set the closing mechanism in operation accidentally. Power operated sliding doors shall be provided with hand gear workable at the door itself on either side and from an accessible position above the bulkhead deck, with an all round crank motion or some other movement providing the same guarantee of safety and of an approved type. Provision shall be made to give warnings by sound signal that the door has begun to close and will continue to move until it is completely closed. The door shall take a sufficient time to close to ensure safety. (ii) There shall be at least two independent power sources capable of opening and closing all the doors under control, each of them capable of operating all the doors simultaneously. The two power sources shall be controlled from the central station on the bridge provided with all the necessary indicators for checking that each of the two power sources is capable of giving the required service satisfactorily. (iii) In the case of hydraulic operation, each power source shall consist of a pump capable of closing all doors in not more than 60 seconds. In addition, there shall be for the whole installation hydraulic accumulators of sufficient capacity to operate all the doors at least three times, ie, closed - open - closed. The fluid used shall be one which does not freeze at any of the temperatures liable to be encountered by the ship during its service. (j) (i) Hinged watertight doors (Class 1) in passenger, crew and working spaces are only permitted above a deck the underside of which, at its lowest point at side, is at least 7 feet (or 2.13 metres) above the deepest subdivision loadline. (ii) Watertight doors, the sills of which are above the deepest loadline and below the line specified in the preceding sub-paragraph shall be sliding doors and may be hand operated (Class 2), except in vessels engaged on short international voyages and required to have a factor of subdivision of .50 or less in which all such doors shall be power operated. When trunkways in connection with refrigerated cargo and ventilation or forced draught ducts are carried through more than one main watertight subdivision bulkhead, the doors at such openings shall be operated by power. (k) (i) Watertight doors which may sometimes be opened at sea, and the sills of which are below the deepest subdivision loadline shall be sliding doors. The following rules shall apply: (1) when the number of such doors (excluding doors at entrances to shaft tunnels) exceeds five, all of these doors and those at the entrance to shaft tunnels or ventilation or forced draught ducts, shall be power operated (Class 3) and shall be capable of being simultaneously closed from a central station situated on the bridge; (2) when the number of such doors (excluding doors at entrances to shaft tunnels) is greater than one, but does not exceed five, (a) where the ship has no passenger spaces below the bulkhead deck, all the above mentioned doors may be hand operated (Class 2); (b) where the ship has passenger spaces below the bulkhead deck all the above mentioned doors shall be power operated (Class 3) and shall be capable of being simultaneously closed from a central station situated on the bridge; (3) in any ship where there are only two such watertight doors and they are into or within the space containing machinery, the Administration may allow these two doors to be hand operated only (Class 2). (ii) If sliding watertight doors which have sometimes to be open at sea for the purpose of trimming coal are fitted between bunkers in the between decks below the bulkhead deck, these doors shall be operated by power. The opening and closing of these doors shall be recorded in such log book as may be prescribed by the Administration. (l) (i) If the Administration is satisfied that such doors are essential, watertight doors of satisfactory construction may be fitted in watertight bulkheads dividing cargo between deck spaces. Such doors may be hinged, rolling or sliding doors but shall not be remotely controlled. They shall be fitted at the highest level and as far from the shell plating as practicable, but in no case shall the outboard vertical edges be situated at a distance from the shell plating which is less than one-fifth of the breadth of the ship, as defined in Regulation 2 of this Chapter, such distance being measured at right angles to the centre line of the ship at the level of the deepest subdivision loadline. (ii) Such doors shall be closed before the voyage commences and shall be kept closed during navigation; and the time of opening such doors in port and of closing them before the ship leaves port shall be entered in the log book. Should any of the doors be accessible during the voyage, they shall be fitted with a device which prevents unauthorized opening. When it is proposed to fit such doors, the number and arrangements shall receive the special consideration of the Administration. (m) Portable plates on bulkheads shall not be permitted except in machinery spaces. Such plates shall always be in place before the ship leaves port, and shall not be removed during navigation except in case of urgent necessity. The necessary precautions shall be taken in replacing them to ensure that the joints shall be watertight. (n) All watertight doors shall be kept closed during navigation except when necessarily opened for the working of the ship, and shall always be ready to be immediately closed. (o) (i) Where trunkways or tunnels for access from crew accommodation to the stokehold, for piping, or for any other purpose are carried through main transverse watertight bulkheads, they shall be watertight and in accordance with the requirements of Regulation 16 of this Chapter. The access to at least one end of each such tunnel or trunkway, if used as a passage at sea, shall be through a trunk extending watertight to a height sufficient to permit access above the margin line. The access to the other end of the trunkway or tunnel may be through a watertight door of the type required by its location in the ship. Such trunkways or tunnels shall not extend through the first subdivision bulkhead abaft the collision bulkhead. (ii) Where it is proposed to fit tunnels or trunkways for forced draught, piercing main transverse watertight bulkheads, these shall receive the special consideration of the Administration. Regulation 14 Openings in the shell plating below the margin line (a) The number of openings in the shell plating shall be reduced to the minimum compatible with the design and proper working of the ship. (b) The arrangement and efficiency of the means for closing any opening in the shell plating shall be consistent with its intended purpose and the position in which it is fitted and generally to the satisfaction of the Administration. (c) (i) If in a between decks, the sills of any sidescuttles are below a line drawn parallel to the bulkhead deck at side and having its lowest point 21/2 per cent of the breadth of the ship above the deepest subdivision loadline, all sidescuttles in that between deck shall be of the non-opening type. (ii) All sidescuttles the sills of which are below the margin line, other than those required to be of a non-opening type by sub-paragraph (i) of this paragraph, shall be of such construction as will effectively prevent any person opening them without the consent of the master of the ship. (iii) (1) Where in a between decks, the sills of any of the sidescuttles referred to in sub-paragraph (ii) of this paragraph are below a line drawn parallel to the bulkhead deck at side and having its lowest point 41/2 feet (or 1.37 metres) plus 21/2 per cent of the breadth of the ship above the water when the ship departs from any port, all the sidescuttles in that between decks shall be closed watertight and locked before the ship leaves port, and they shall not be opened before the ship arrives at the next port. In the application of this sub-paragraph the appropriate allowance for fresh water may be made when applicable. (2) The time of opening such sidescuttles in port and of closing and locking them before the ship leaves port shall be entered in such log book as may be prescribed by the Administration.
(3) For any ship that has one or more sidescuttles so placed that the requirements of clause (1) of this sub-paragraph would apply when she was floating at her deepest subdivision loadline, the Administration may indicate the limiting mean draught at which these sidescuttles will have their sills above the line drawn parallel to the bulkhead deck at side, and having its lowest point 41/2 feet (or 1.37 metres) plus 21/2 per cent of the breadth of the ship above the waterline corresponding to the limiting mean draught, and at which it will therefore be permissible to depart from port without previously closing and locking them and to open them at sea on the responsibility of the master during the voyage to the next port. In tropical zones as defined in the International Convention respecting Load Lines in force, this limiting draught may be increased by 1 foot (or 0.305 metres). (d) Efficient hinged inside deadlights arranged so that they can be easily and effectively closed and secured watertight shall be fitted to all sidescuttles except that abaft one-eighth of the ship's length from the forward perpendicular and above a line drawn parallel to the bulkhead deck at side and having its lowest point at a height of 12 feet (or 3.66 metres) plus 21/2 per cent of the breadth of the ship above the deepest subdivision loadline, the deadlights may be portable in passenger accommodation other than that for steerage passengers, unless the deadlights are required by the International Convention respecting Load Lines in force to be permanently attached in their proper positions. Such portable deadlights shall be stowed adjacent to the sidescuttles they serve. (e) Sidescuttles and their deadlights, which will not be accessible during navigation, shall be closed and secured before the ship leaves port. (f) (i) No sidescuttles shall be fitted in any spaces which are appropriated exclusively to the carriage of cargo or coal. (ii) Sidescuttles may, however, be fitted in spaces appropriated alternatively to the carriage of cargo or passengers, but they shall be of such construction as will effectively prevent any person opening them or their deadlights without the consent of the master of the ship. (iii) If cargo is carried in such spaces, the sidescuttles and their deadlights shall be closed watertight and locked before the cargo is shipped and such closing and locking shall be recorded in such log book as may be prescribed by the Administration. (g) Automatic ventilating sidescuttles shall not be fitted in the shell plating below the margin line without the special sanction of the Administration. (h) The number of scuppers, sanitary discharges and other similar openings in the shell plating shall be reduced to the minimum either by making each discharge serve for as many as possible of the sanitary and other pipes, or in any other satisfactory manner. (i) (i) All inlets and discharges in the shell plating shall be fitted with efficient and accessible arrangements for preventing the accidental admission of water into the ship. Lead or other heat sensitive materials shall not be used for pipes fitted outboard of shell valves in inlets or discharges, or any other application where the deterioration of such pipes in the event of fire would give rise to danger of flooding. (ii) (1) Except as provided in sub-paragraph (iii) of this paragraph, each separate discharge led through the shell plating from spaces below the margin line shall be provided either with one automatic non-return valve fitted with a positive means of closing it from above the bulkhead deck, or, alternatively, with two automatic non-return valves without such means, the upper of which is so situated above the deepest subdivision loadline as to be always accessible for examination under service conditions, and is of a type which is normally closed. (2) Where a valve with positive means of closing is fitted, the operating position above the bulkhead deck shall always be readily accessible, and means shall be provided for indicating whether the valve is open or closed. (iii) Main and auxiliary sea inlets and discharges in connection with machinery shall be fitted with readily accessible cocks or valves between the pipes and shell plating or between the pipes and fabricated boxes attached to the shell plating. (j) (i) Gangway, cargo and coaling ports fitted below the margin line shall be of sufficient strength. They shall be effectively closed and secured watertight before the ship leaves port, and shall be kept closed during navigation. (ii) Such ports shall be in no case fitted so as to have their lowest point below the deepest subdivision loadline. (k) (i) The inboard opening of each ash-shoot, rubbish-shoot, &c., shall be fitted with an efficient cover. (ii) If the inboard opening is situated below the margin line, the cover shall be watertight, and in addition an automatic non-return valve shall be fitted in the shoot in an easily accessible position above the deepest subdivision loadline. When the shoot is not in use both the cover and the valve shall be kept closed and secured. Regulation 15 Construction and initial tests of watertight doors, sidescuttles, &c. (a) (i) The design, materials and construction of all watertight doors, sidescuttles, gangway, cargo and coaling ports, valves, pipes, ash-shoots and rubbish-shoots referred to in these Regulations shall be to the satisfaction of the Administration. (ii) The frames of vertical watertight doors shall have no groove at the bottom in which dirt might lodge and prevent the door closing properly. (iii) All cocks and valves for sea inlets and discharges below the bulkhead deck and all fittings outboard of such cocks and valves shall be made of steel, bronze or other approved ductile material. Ordinary cast iron or similar materials shall not be used. (b) Each watertight door shall be tested by water pressure to a head up to the bulkhead deck. The test shall be made before the ship is put in service, either before or after the door is fitted. Regulation 16 Construction and initial tests of watertight decks, trunks, &c. (a) Watertight decks, trunks, tunnels, duct keels and ventilators shall be of the same strength as watertight bulkheads at corresponding levels. The means used for making them watertight, and the arrangements adopted for closing openings in them, shall be to the satisfaction of the Administration. Watertight ventilators and trunks shall be carried at least up to the bulkhead deck. (b) After completion, a hose or flooding test shall be applied to watertight decks and a hose test to watertight trunks, tunnels and ventilators. Regulation 17 Watertight integrity above the margin line (a) The Administration may require that all reasonable and practicable measures shall be taken to limit the entry and spread of water above the bulkhead deck. Such measures may include partial bulkheads or webs. When partial watertight bulkheads and webs are fitted on the bulkhead deck, above or in the immediate vicinity of main subdivision bulkheads, they shall have watertight shell and bulkhead deck connections so as to restrict the flow of water along the deck when the ship is in a heeled damaged condition. Where the partial watertight bulkhead does not line up with the bulkhead below, the bulkhead deck between shall be made effectively watertight. (b) The bulkhead deck or a deck above it shall be weathertight in the sense that in ordinary sea conditions water will not penetrate in a downward direction. All openings in the exposed weather deck shall have coamings of ample height and strength and shall be provided with efficient means for expeditiously closing them weathertight. Freeing ports, open rails and/or scuppers shall be fitted as necessary for rapidly clearing the weather deck of water under all weather conditions. (c) Sidescuttles, gangway, cargo and coaling ports and other means for closing openings in the shell plating above the margin line shall be of efficient design and construction and of sufficient strength having regard to the spaces in which they are fitted and their positions relative to the deepest subdivision loadline. (d) Efficient inside deadlights, arranged so that they can be easily and effectively closed and secured watertight, shall be provided for all sidescuttles to spaces below the first deck above the bulkhead deck. Regulation 18 Bilge pumping arrangements in passenger ships (a) Ships shall be provided with an efficient bilge pumping plant capable of pumping from and draining any watertight compartment which is neither a permanent oil compartment nor a permanent water compartment under all practicable conditions after a casualty whether the ship is upright or listed. For this purpose wing suctions will generally be necessary except in narrow compartments at the ends of the ship, where one suction may be sufficient. In compartments of unusual form, additional suctions may be required. Arrangements shall be made whereby water in the compartment may find its way to the suction pipes. Where in relation to particular compartments the Administration is satisfied that the provision of drainage may be undesirable, it may allow such provision to be dispensed with if calculations made in accordance with the conditions laid down in paragraph (b) of Regulation 7 of this Chapter show that the safety of the ship will not be impaired. Efficient means shall be provided for draining water from insulated holds. (b) (i) Ships shall have at least three power pumps connected to the bilge main, one of which may be attached to the propelling unit. Where the criterion numeral is 30 or more, one additional independent power pump shall be provided. (ii) The requirements are summarised in the following table:
(iii) Sanitary, ballast and general service pumps may be accepted as independent power bilge pumps if fitted with the necessary connections to the bilge pumping system. (c) Where practicable, the power bilge pumps shall be placed in separate watertight compartments so arranged or situated that these compartments will not readily be flooded by the same damage. If the engines and boilers are in two or more watertight compartments, the pumps available for bilge service shall be distributed throughout these compartments as far as is possible. (d) On ships 300 feet (or 91.5 metres) or more in length or having a criterion numeral of 30 or more, the arrangements shall be such that at least one power pump shall be available for use in all ordinary circumstances in which a ship may be flooded at sea. This requirement will be satisfied if: (i) one of the required pumps is an emergency pump of a reliable submersible type having a source of power situated above the bulkhead deck; or (ii) the pumps and their sources of power are so disposed throughout the length of the ship that under any condition of flooding which the ship is required to withstand, at least one pump in an undamaged compartment will be available. (e) With the exception of additional pumps which may be provided for peak compartments only, each required bilge pump shall be arranged to draw water from any space required to be drained by paragraph (a) of this Regulation. (f) (i) Each power bilge pump shall be capable of giving a speed of water through the required main bilge pipe of not less than 400 feet (or 122 metres) per minute. Independent power bilge pumps situated in machinery spaces shall have direct suctions from these spaces, except that not more than two such suctions shall be required in any one space. Where two or more such suctions are provided there shall be at least one on the port side and one on the starboard side. The Administration may require independent power bilge pumps situated in other spaces to have separate direct suctions. Direct suctions shall be suitably arranged and those in a machinery space shall be of a diameter not less than that required for the bilge main. (ii) In coal-burning ships there shall be provided in the stokehold, in addition to the other suctions required by this Regulation, a flexible suction hose of suitable diameter and sufficient length, capable of being connected to the suction side of an independent power pump. (g) (i) In addition to the direct bilge suction or suctions required by paragraph (f) of this Regulation there shall be in the machinery space a direct suction from the main circulating pump leading to the drainage level of the machinery space and fitted with a non-return valve. The diameter of this direct suction pipe shall be at least two-thirds of the diameter of the pump inlet in the case of steamships, and of the same diameter as the pump inlet in the case of motorships. (ii) Where in the opinion of the Administration the main circulating pump is not suitable for this purpose, a direct emergency bilge suction shall be led from the largest available independent power driven pump to the drainage level of the machinery space; the suction shall be of the same diameter as the main inlet of the pump used. The capacity of the pump so connected shall exceed that of a required bilge pump by an amount satisfactory to the Administration. (iii) The spindles of the sea inlet and direct suction valves shall extend well above the engine room platform. (iv) Where the fuel is, or may be, coal and there is no watertight bulkhead between the engines and the boilers, a direct discharge overboard or alternatively a by-pass to the circulating pump discharge, shall be fitted from any circulating pump used in compliance with sub-paragraph (i) of this paragraph. (h) (i) All pipes from the pumps which are required for draining cargo or machinery spaces shall be entirely distinct from pipes which may be used for filling or emptying spaces where water or oil is carried (ii) All bilge pipes used in or under coal bunkers or fuel storage tanks or in boiler or machinery spaces, including spaces in which oil-settling tanks or oil fuel pumping units are situated, shall be of steel or other approved material. (i) The diameter of the bilge main shall be calculated according to the following formulae provided that the actual internal diameter of the bilge main may be of the nearest standard size acceptable to the Administration:
where d = internal diameter of the bilge main in inches L = length of ship in feet B = breadth of ship in feet D = moulded depth of ship to bulkhead deck in feet; or
where d = internal diameter of the bilge main in millimetres L = length of ship in metres B = breadth of ship in metres D = moulded depth of ship to bulkhead deck in metres. The diameter of the bilge branch pipes shall be determined by rules to be made by the Administration. (j) The arrangement of the bilge and ballast pumping system shall be such as to prevent the possibility of water passing from the sea and from water ballast spaces into the cargo and machinery spaces, or from one compartment to another. Special provision shall be made to prevent any deep tank having bilge and ballast connections being inadvertently run up from the sea when containing cargo, or pumped out through a bilge pipe when containing water ballast. (k) Provision shall be made to prevent the compartment served by any bilge suction pipe being flooded in the event of the pipe being severed, or otherwise damaged by collision or grounding in any other compartment. For this purpose, where the pipe is at any part situated nearer the side of the ship than one-fifth the breadth of the ship (measured at right angles to the centre line at the level of the deepest subdivision load line), or in a duct keel, a non-return valve shall be fitted to the pipe in the compartment containing the open end. (l) All the distribution boxes, cocks and valves in connection with the bilge pumping arrangements shall be in positions which are accessible at all times under ordinary circumstances. They shall be so arranged that, in the event of flooding, one of the bilge pumps may be operative on any compartment; in addition, damage to a pump or its pipe connecting to the bilge main outboard of a line drawn at one-fifth of the breadth of the ship shall not put the bilge system out of action. If there is only one system of pipes common to all the pumps, the necessary cocks or valves for controlling the bilge suctions must be capable of being operated from above the bulkhead deck. Where in addition to the main bilge pumping system an emergency bilge pumping system is provided, it shall be independent of the main system and so arranged that a pump is capable of operating on any compartment under flooding conditions; in that case only the cocks and valves necessary for the operation of the emergency system need be capable of being operated from above the bulkhead deck. (m) All cocks and valves mentioned in paragraph (l) of this Regulation which can be operated from above the bulkhead deck shall have their controls at their place of operation clearly marked and provided with means to indicate whether they are open or closed. Regulation 19 Stability information for passenger ships and cargo ships (a) Every passenger ship and cargo ship shall be inclined upon its completion and the elements of its stability determined. The master shall be supplied with such reliable information as is necessary to enable him by rapid and simple processes to obtain accurate guidance as to the stability of the ship under varying conditions of service, and a copy shall be furnished to the Administration. (b) Where any alterations are made to a ship so as to materially affect the stability information supplied to the master, amended stability information shall be provided. If necessary the ship shall be re-inclined. (c) The Administration may allow the inclining test of an individual ship to be dispensed with provided basic stability data are available from the inclining test of a sister ship and it is shown to the satisfaction of the Administration that reliable stability information for the exempted ship can be obtained from such basic data. (d) The Administration may also allow the inclining test of an individual ship or class of ships, especially designed for the carriage of liquids or ore in bulk, to be dispensed with when reference to existing data for similar ships clearly indicate that due to the ship's proportions and arrangements more than sufficient metacentric height will be available in all probable loading conditions. Regulation 20 Damage control plans There shall be permanently exhibited, for the guidance of the officer in charge of the ship, plans showing clearly for each deck and hold the boundaries of the watertight compartments, the openings therein with the means of closure and position of any controls thereof, and the arrangements for the correction of any list due to flooding. In addition, booklets containing the aforementioned information shall be made available to the officers of the ship. Regulation 21 Marking, periodical operation and inspection of watertight doors, &c. (a) This Regulation applies to new and existing ships. (b) Drills for the operating of watertight doors, sidescuttles, valves and closing mechanisms of scuppers, ash-shoots and rubbish-shoots shall take place weekly. In ships which the voyage exceeds one week in duration a complete drill shall be held before leaving port, and others thereafter at least once a week during the voyage. In all ships all watertight power doors and hinged doors, in main transverse bulkheads, in use at sea, shall be operated daily. (c) (i) The watertight doors and all mechanisms and indicators connected therewith, all valves the closing of which is necessary to make a compartment watertight, and all valves the operation of which is necessary for damage control cross connections shall be periodically inspected at sea at least once a week. (ii) Such valves, doors and mechanisms shall be suitably marked to ensure that they may be properly used to provide maximum safety. Regulation 22 Entries in log (a) This Regulation applies to new and existing ships. (b) Hinged doors, portable plates, sidescuttles, gangway, cargo and coaling ports and other openings, which are required by these Regulations to be kept closed during navigation, shall be closed before the ship leaves port. The time of closing and the time of opening (if permissible under these Regulations) shall be recorded in such log book as may be prescribed by the Administration. (c) A record of all drills and inspections required by Regulation 21 of this Chapter shall be entered in the log book with an explicit record of any defects which may be disclosed. PART C MACHINERY AND ELECTRICAL INSTALLATIONS (Part C applies to passenger ships and cargo ships) Regulation 23 General (a) Electrical installations in passenger ships shall be such that: (i) services essential for safety will be maintained under various emergency conditions; and (ii) the safety of passengers, crew and ship from electrical hazards will be assured. (b) Cargo ships shall comply with Regulations 26, 27, 28, 29, 30 and 33 of this Chapter. Regulation 24 Main source of electrical power in passenger ships (a) Every passenger ship, the electrical power of which constitutes the only means of maintaining the auxiliary services indispensable for the propulsion and the safety of the ship, shall be provided with at least two main generating sets. The power of these sets shall be such that it shall still be possible to ensure the functioning of the services referred to in sub-paragraph (a)(i) of Regulation 23 of this Chapter in the event of any one of these generating sets being stopped. (b) In a passenger ship where there is only one main generating station, the main switchboard shall be located in the same main fire zone. Where there is more than one main generating station, it is permissible to have only one main switchboard. Regulation 25 Emergency source of electrical power in passenger ships (a) There shall be above the bulkhead deck and outside the machinery casings a self-contained emergency source of electrical power. Its location in relation to the main source or sources of electrical power shall be such as to ensure to the satisfaction of the Administration that a fire or other casualty to the machinery space as defined in paragraph (h) of Regulation 2 of this Chapter will not interfere with the supply or distribution of emergency power. It shall not be forward of the collision bulkhead. (b) The power available shall be sufficient to supply all those services that are, in the opinion of the Administration, necessary for the safety of the passengers and the crew in an emergency, due regard being paid to such services as may have to be operated simultaneously. Special consideration shall be given to emergency lighting at every boat station on deck and oversides, in all alleyways, stairways and exits, in the machinery spaces and in the control stations as defined in paragraph (f) of Regulation 35 of this Chapter, to the sprinkler pump, to navigation lights, and to the daylight signalling lamp if operated from the main source of power. The power shall be adequate for a period of 36 hours, except that, in the case of ships engaged regularly on voyages of short duration, the Administration may accept a lesser supply if satisfied that the same standard of safety would be attained. (c) The emergency source of power may be either: (i) a generator driven by a suitable prime-mover with an independent fuel supply and with approved starting arrangements; the fuel used shall have a flash point of not less than 110deg.F or (43deg.C); or (ii) an accumulator (storage) battery capable of carrying the emergency load without recharging or excessive voltage drop. (d) (i) Where the emergency source of power is a generator there shall be provided a temporary source of emergency power consisting of an accumulator battery of sufficient capacity: (1) to supply emergency lighting continuously for half an hour; (2) to close the watertight doors (if electrically operated) but not necessarily to close them all simultaneously; (3) to operate the indicators (if electrically operated) which show whether power operated watertight doors are open or closed; and (4) to operate the sound signals (if electrically operated) which give warning that power operated watertight doors are about to close. The arrangements shall be such that the temporary source of emergency power will come into operation automatically in the event of failure of the main electrical supply. (ii) Where the emergency source of power is an accumulator battery, arrangements shall be made to ensure that emergency lighting will automatically come into operation in the event of failure of the main lighting supply. (e) An indicator shall be mounted in the machinery space, preferably on the main switchboard, to indicate when any accumulator battery fitted in accordance with this Regulation is being discharged. (f) (i) The emergency switchboard shall be installed as near as is practicable to the emergency source of power. (ii) Where the emergency source of power is a generator, the emergency switchboard shall be located in the same space as the emergency source of power, unless the operation of the emergency switchboard would thereby be impaired. (iii) No accumulator battery fitted in accordance with this Regulation shall be installed in the same space as the emergency switchboard. (iv) The Administration may permit the emergency switchboard to be supplied from the main switchboard in normal operation. (g) Arrangements shall be such that the complete emergency installation will function when the ship is inclined 221/2 degrees and/or when the trim of the ship is 10 degrees. (h) Provision shall be made for the periodic testing of the emergency source of power and the temporary source of power, if provided, which shall include the testing of automatic arrangements. Regulation 26 Emergency source of electrical power in cargo ships (a) Cargo ships of 5,000 tons gross tonnage and upwards (i) In cargo ships of 5,000 tons gross tonnage and upwards there shall be a self-contained emergency source of power, located to the satisfaction of the Administration above the uppermost continuous deck and outside the machinery casings, to ensure its functioning in the event of fire or other casualty causing failure to the main electrical installation. (ii) The power available shall be sufficient to supply all those services which are, in the opinion of the Administration, necessary for the safety of all on board in an emergency, due regard being paid to such services as may have to be operated simultaneously. Special consideration shall be given to: (1) emergency lighting at every boat station on deck and oversides, in an alleyways, stairways and exits, in the main machinery space and main generating set space, on the navigating bridge and in the chartroom; (2) the general alarm; and (3) navigation lights if solely electric, and the daylight signalling lamp if operated by the main source of electrical power. The power shall be adequate for a period of 6 hours.

PART D FIRE PROTECTION (In Part D, Regulations 34 to 52 apply to passenger ships carrying more than 36 passengers; Regulations 35 and 53 apply to passenger ships carrying not more than 36 passengers; Regulations 35 and 54 apply to cargo ships of 4,000 tons gross tonnage and upwards.) Regulation 34 General (a) The purpose of this Part is to require the fullest practicable degree of protection from fire by regulation of the details of arrangement and construction. The three basic principles underlying these regulations are: (i) separation of the accommodation spaces from the remainder of the ship by thermal and structural boundaries; (ii) containment, extinction, or detection of any fire in the space of origin; (iii) protection of means of escape. (b) The hull, superstructure and deck houses shall be divided into main vertical zones by "A" Class bulkheads (as described in paragraph (c) of Regulation 35 of this Chapter) and further divided by similar bulkheads forming the boundaries protecting spaces which provide vertical access and the boundaries separating the accommodation spaces from the machinery, cargo and service spaces and others. In addition, and supplementary to the patrol systems, alarm systems and fire extinguishing apparatus required by Part E of this Chapter, either of the following methods of protection, or a combination of these methods to the satisfaction of the Administration, shall be adopted in accommodation and service spaces with a view to preventing the spread of incipient fires from the spaces of their origin: Method I. - The construction of internal divisional bulkheading of "B" Class divisions (as defined in paragraph (d) of Regulation 35 of this Chapter) generally without the installation of a detection or sprinkler system in the accommodation and service spaces; or Method II. - The fitting of an automatic sprinkler and fire alarm system for the detection and extinction of fire in all spaces in which a fire might be expected to originate, generally with no restriction on the type of internal divisional bulkheading in spaces so protected; or Method III. - A system of subdivision within each main vertical zone using "A" and "B" Class divisions distributed according to the importance, size and nature of the various compartments, with an automatic fire detection system in all spaces in which a fire might be expected to originate, and with restricted use of combustible and highly inflammable materials and furnishings; but generally without the installation of a sprinkler system. Where appropriate, the headings or sub-headings of the Regulations of this Part of this Chapter indicate under which Method or Methods the Regulation is a requirement. Regulation 35 Definitions Wherever the phrases defined below occur throughout this Part of this Chapter, they shall be interpreted in accordance with the following definitions: (a) Incombustible material means a material which neither burns nor gives off inflammable vapours in sufficient quantity to ignite at a pilot flame when heated to approximately 1,382deg.F (or 750deg.C). Any other material is a "Combustible material". (b) A standard fire test is one in which specimens of the relevant bulkheads or decks, having a surface of approximately 50 square feet (or 4.65 square metres) and height of 8 feet (or 2.44 metres) resembling as closely as possible the intended construction and including where appropriate at least one joint, are exposed in a test furnace to a series of time temperature relationships, approximately as follows: at the end of the first 5 minutes - 1,000deg.F (or 538deg.C) at the end of the first 10 minutes - 1,300deg.F (or 704deg.C) at the end of the first 30 minutes - 1,550deg.F (or 843deg.C) at the end of the first 60 minutes - 1,700deg.F (or 927deg.C) (c) "A" Class or fire-resisting divisions are those divisions formed by bulkheads and decks which comply with the following: (i) they shall be constructed of steel or other equivalent material; (ii) they shall be suitably stiffened; (iii) they shall be so constructed as to be capable of preventing the passage of smoke and flame up to the end of the one-hour standard fire test; (iv) they shall have an insulating value to the satisfaction of the Administration, having regard to the nature of the adjacent spaces. In general, where such bulkheads and decks are required to form fire-resisting divisions between spaces either of which contains adjacent woodwork, wood lining, or other combustible material, they shall be so insulated that, if either face is exposed to the standard fire test for one hour, the average temperature on the unexposed face will not increase at any time during the test by more than 250deg.F (or 139deg.C) above the initial temperature nor shall the temperature at any point on the face, including any joint, rise more than 325deg.F (or 180deg.C) above the initial temperature. Reduced amounts of insulation or none at all may be provided where in the opinion of the Administration a reduced fire hazard is present. The Administration may require a test of an assembled prototype bulkhead or deck to ensure that it meets the above requirements for integrity and temperature rise. (d) "B" Class or fire-retarding divisions are those divisions formed by bulkheads which are so constructed that they will be capable of preventing the passage of flame up to the end of the first one-half hour of the standard fire test. In addition they shall have an insulating value to the satisfaction of the Administration, having regard to the nature of the adjacent spaces. In general, where such bulkheads are required to form fire-retarding divisions between spaces, they shall be of such material that, if either face is exposed for the first one-half hour period of the standard fire test, the average temperature on the unexposed face will not increase at any time during the test by more than 250deg.F (or 139deg.C) above the initial temperature, nor shall the temperature at any point on the face including any joint rise more than 405deg.F (or 225deg.C) above the initial temperature. For panels which are of incombustible materials it will only be necessary to comply with the above temperature rise limitation during the first 15-minute period of the standard fire test, but the test shall be continued to the end of the one-half hour to test the panel's integrity in the usual manner. All materials entering into the construction and erection of incombustible "B" Class divisions shall themselves be of incombustible material. Reduced amounts of insulation or none at all may be provided where in the opinion of the Administration a reduced fire hazard is present. The Administration may require a test of an assembled prototype bulkhead to ensure that it meets the above requirements for integrity and temperature rise. (e) Main vertical zones are those sections into which the hull, superstructure, and deck houses are divided by "A" Class divisions, the mean length of which on any one deck does not, in general, exceed 131 feet (or 40 metres). (f) Control stations are those spaces in which radio, main navigating or central fire-recording equipment or the emergency generator is located. (g) Accommodation spaces are those used for public spaces, corridors, lavatories, cabins, offices, crew quarters, barber shops, isolated pantries and lockers and similar spaces. (h) Public spaces are those portions of the accommodation which are used for halls, dining rooms, lounges and similar permanently enclosed spaces. (i) Service spaces are those used for galleys, main pantries, stores (except isolated pantries and lockers), mail and specie rooms and similar spaces and trunks to such spaces. (j) Cargo spaces are all spaces used for cargo (including cargo oil tanks) and trunks to such spaces. (k) Machinery spaces include all spaces used for propelling, auxiliary or refrigerating machinery, boilers, pumps, workshops, generators, ventilation and air conditioning machinery, oil filling stations and similar spaces and trunks to such spaces. (l) Steel or other equivalent material. - Where the words "steel or other equivalent material" occur, "equivalent material" means any material which, by itself or due to insulation provided, has structural and integrity properties equivalent to steel at the end of the applicable fire exposure (eg, aluminium with appropriate insulation). (m) Low flame spread means that the surface thus described will adequately restrict the spread of flame having regard to the risk of fire in the spaces concerned, this being determined to the satisfaction of the Administration by a suitably established test procedure. Regulation 36 Structure (Methods I, II and III) (a) Method I The hull, superstructure, structural bulkheads, decks and deckhouses shall be constructed of steel or other equivalent material. (b) Method II (i) The hull, superstructure, structural bulkheads, decks and deckhouses shall be constructed of steel or other equivalent material. (ii) Where fire protection in accordance with Method II is employed, the superstructure may be constructed of, for example, aluminium alloy, provided that: (1) the temperature rise of the metallic cores of the "A" Class divisions, when exposed to the standard fire test, shall have regard to the mechanical properties of the material; (2) an automatic sprinkler system complying with paragraph (g) of Regulation 59 of this Chapter is installed; (3) adequate provision is made to ensure that in the event of fire, arrangements for stowage, launching and embarkation into survival craft remain as effective as if the superstructure were constructed of steel; (4) crowns and casings of boiler and machinery spaces are of steel construction adequately insulated, and the openings therein, if any, are suitably arranged and protected to prevent spread of fire. (c) Method III (i) The hull, superstructure, structural bulkheads, decks and deckhouses shall be constructed of steel or other equivalent material. (ii) Where fire protection in accordance with Method III is employed, the superstructure may be constructed of, for example, aluminium alloy, provided that: (1) the temperature rise of the metallic cores of the "A" Class divisions, when .exposed to the standard fire test, shall have regard to the mechanical properties of the material; (2) the Administration shall be satisfied that the amount of combustible materials used in the relevant part of the ship is suitably reduced. Ceilings (ie, linings of deck heads) shall be incombustible; (3) adequate provision is made to ensure that in the event of fire, arrangements for stowage, launching and embarkation into survival craft remain as effective as if the superstructure were constructed of steel; (4) crowns and casings of boiler and machinery spaces are of steel construction adequately insulated, and the openings therein, if any, are suitably arranged and protected to prevent spread of fire. Regulation 37 Main vertical zones (Methods I, II and III) (a) The hull, superstructure and deckhouses shall be subdivided into main vertical zones. Steps and recesses shall be kept to a minimum, but where they are necessary, they shall be of "A" Class divisions. (b) As far as practicable, the bulkheads forming the boundaries of the main vertical zones above the bulkhead deck shall be in line with watertight subdivision bulkheads situated immediately below the bulkhead deck. (c) Such bulkheads shall extend from deck to deck and to the shell or other boundaries. (d) On ships designed for special purposes, such as automobile or railroad car ferries, where installation of such bulkheads would defeat the purpose for which the ship is intended, equivalent means for controlling and limiting a fire shall be substituted and specifically approved by the Administration. Regulation 38 Openings in "A" Class divisions (Methods I, II and III) (a) Where "A" Class divisions are pierced for the passage of electric cables, pipes, trunks, ducts, &c., for girders, beams or other structures, arrangements shall be made to ensure that the fire resistance is not impaired. (b) Dampers are to be fitted in ventilation trunks and ducts passing through main vertical zone bulkheads, and shall be fitted with suitable local control capable of being operated from both sides of the bulkhead. The operating positions shall be readily accessible and marked in red. Indicators shall be fitted to show whether the dampers are open or shut. (c) Except for tonnage openings and for hatches between cargo, store, and baggage spaces, and between such spaces and the weather decks, all openings shall be provided with permanently attached means of closing which shall be at least as effective for resisting fires as the divisions in which they are fitted. Where "A" Class divisions are pierced by tonnage openings the means of closure shall be by steel plates. (d) The construction of all doors and door frames in "A" Class divisions, with the means of securing them when closed, shall provide resistance to fire as well as to the passage of smoke and flame as far as practicable equivalent to that of the bulkheads in which the doors are situated. Watertight doors need not be insulated. (e) It shall be possible for each door to be opened from either side of the bulkhead by one person only. Fire doors in main vertical zone bulkheads other than watertight doors shall be of the self-closing type with simple and easy means of release from the open position. These doors shall be of approved types and designs, and the self-closing mechanism shall be capable of closing the door against an inclination of 31/2 degrees opposing closure. Regulation 39 Bulkheads within main vertical zones (Methods I and III) (a) Method I (i) Within the accommodation spaces, all enclosure bulkheads, other than those required to be of "A" Class divisions, shall be constructed of "B" Class divisions of incombustible materials, which may, however, be faced with combustible materials in accordance with Regulation 48 of this Chapter.

(b) Method III (i) Within the accommodation spaces, enclosure bulkheads other than those required to be of "A" Class divisions shall be constructed of "B" Class divisions, and shall be of incombustible materials which may, however, be faced with combustible materials in accordance with Regulation 48 of this Chapter. These bulkheads shall form a continuous network of fire-retarding bulkheads within which the area of any one compartment shall not in general exceed 1,300 square feet (or 120 square metres) with a maximum of 1,600 square feet (or 150 square metres); they shall extend from deck to deck. All doorways and similar openings shall have a method of closure consistent with the type of bulkhead in which they are situated. (ii) Each public space larger than 1,600 square feet (or 150 square metres) shall be surrounded by "B" Class divisions of incombustible materials. (iii) The insulation of "A" Class and "B" Class divisions, except those constituting the separation of the main vertical zones, the control stations, the stairway enclosures, and the corridors, may be omitted when the divisions constitute the outside part of the ship or when the adjoining compartment does not contain fire hazard. (iv) All corridor bulkheads shall be of "B" Class divisions and shall extend from deck to deck. Ceilings, if fitted, shall be of incombustible materials. Ventilation openings may be permitted in doors, preferably in the lower portion. All other partition bulkheads shall also extend from deck to deck vertically and to the shell or other boundaries transversely, unless incombustible ceilings or linings are fitted, in which case the bulkheads may terminate at the ceilings or linings. (v) "B" Class divisions other than those required to be of the incombustible type shall have incombustible cores or be of an assembled type having internal layers of sheet asbestos or similar incombustible material.

(2) In addition, in each compartment containing explosives and in adjacent cargo compartments, there shall be provided a smoke or fire detection system in each cargo space. (g) Fire extinguishing appliances in boiler rooms, &c. Where main or auxiliary oil fired boilers are situated, or in spaces containing oil fuel units or settling tanks, a cargo ship of 1,000 tons gross tonnage and upwards shall be provided with the following arrangements: (i) There shall be any one of the following fixed fire extinguishing installations: (1) A pressure water spraying system complying with Regulation 62 of this Chapter; (2) A fire smothering gas installation complying with Regulation 58 of this Chapter; (3) A fixed froth installation complying with Regulation 60 of this Chapter. (The Administration may require fixed or mobile arrangements by pressure water or froth spraying to fight fire above the floor plates.) In each case if the engine and boiler rooms are not entirely separate, or if fuel oil can drain from the boiler room into the engine room bilges, the combined engine and boiler rooms shall be considered as one compartment. (ii) There shall be at least two approved portable extinguishers discharging froth or other approved medium suitable for extinguishing oil fires in each firing space in each boiler room and each space in which a part of the oil fuel installation is situated. In addition, there shall be at least one extinguisher of the same description with a capacity of 2 gallons (or 9 litres) for each burner, provided that the total capacity of the additional extinguisher or extinguishers need not exceed 10 gallons (or 45 litres) for any one boiler room. (iii) In each firing space there shall be a receptacle containing sand, sawdust impregnated with soda, or other approved dry material in such quantity as may be required by the Administration. Alternatively an approved portable extinguisher may be substituted therefor. (h) Fire fighting appliances in spaces containing internal combustion type machinery Where internal combustion type engines are used, either (1) for main propulsion machinery, or (2) for auxiliary purposes associated with a total power not less than 1,000 b.h.p., a cargo ship of 1,000 tons gross tonnage and upwards shall be provided with the following arrangements: (i) There shall be one of the fixed arrangements required by sub-paragraph (g)(i) of this Regulation. (ii) There shall be in each engine space one approved froth type extinguisher of not less than 10 gallons (or 45 litres) capacity or equivalent and also one approved portable froth extinguisher for each 1,000 b.h.p. of the engines or part thereof; but the total number of portable extinguishers so supplied shall be not less than two and need not exceed six. (i) Fire fighting arrangements in spaces containing steam turbines and not requiring any fixed installation The Administration shall give special consideration to the fire extinguishing arrangements to be provided in spaces containing steam turbines which are separated from boiler rooms by watertight bulkheads. (j) Fireman's outfit A cargo ship shall carry at least one fireman's outfit complying with the requirements of Regulation 63 of this Chapter. Regulation 66 Ready availability of fire fighting appliances Fire extinguishing appliances in new and existing passenger ships and cargo ships shall be kept in good order and available for immediate use at all times during the voyage. Regulation 67 Acceptance of substitutes Where in this Part of this Chapter any special type of appliance, apparatus, extinguishing medium or arrangement is specified, any other type of appliance, &c. may be allowed, provided the Administration is satisfied that it is not less effective. PART F GENERAL FIRE PRECAUTIONS (Part F applies to passenger ships and cargo ships) Regulation 68 Means of escape (a) Passenger ships (i) In and from all passenger and crew spaces and spaces in which crew are normally employed, other than machinery spaces, stairways and ladderways shall be arranged so as to provide ready means of escape to the lifeboat embarkation deck. In particular the following precautions shall be complied with: (1) below the bulkhead deck, two means of escape, at least one of which shall be independent of watertight doors, shall be provided for each watertight compartment or similarly restricted space or group of spaces. One of these means of escape may be dispensed with by the Administration, due regard being paid to the nature and the location of spaces concerned, and to the number of persons who normally might be quartered or employed there; (2) above the bulkhead deck, there shall be at least two practical means of escape from each main vertical zone or similarly restricted space or group of spaces at least one of which shall give access to a stairway forming a vertical escape; (3) at least one of the means of escape shall be by means of a readily accessible enclosed stairway, which shall provide as far as practicable continuous fire shelter from the level of its origin to the lifeboat embarkation deck. The width, number and continuity of the stairways shall be to the satisfaction of the Administration. (ii) In machinery spaces, two means of escape, one of which may be a watertight door, shall be provided from each engine room, shaft tunnel and boiler room. In machinery spaces, where no watertight door is available, the two means of escape shall be formed by two sets of steel ladders as widely separated as possible leading to doors in the casing similarly separated and from which access is provided to the embarkation deck. In the case of ships of less than 2,000 tons gross tonnage, the Administration may dispense with this requirement, due regard being paid to the width and the disposition of the casing. (b) Cargo ships (i) In and from all crew and passenger spaces and spaces in which crew are normally employed, other than machinery spaces, stairways and ladders shall be arranged so as to provide ready means of escape to the lifeboat embarkation deck. (ii) In machinery spaces, the requirements of sub-paragraph (a)(ii) of this Regulation shall apply. Regulation 69 Means for stopping machinery and for shutting off fuel suction pipes (a) Means shall be provided for stopping ventilating fans serving machinery and cargo spaces and for closing all doorways, ventilators, annular spaces around funnels and other openings to such spaces. These means shall be capable of being operated from outside such spaces in case of fire. (b) Machinery driving forced and induced draught fans, oil fuel transfer pumps, oil fuel unit pumps and other similar fuel pumps shall be fitted with remote controls situated outside the space concerned so that they may be stopped in the event of a fire arising in the space in which they are located. (c) Every oil fuel suction pipe from a storage, settling or daily service tank situated above the double bottom shall be fitted with a cock or valve capable of being closed from outside the space concerned in the event of a fire arising in the space in which such tanks are situated. In the special case of deep tanks situated in any shaft or pipe tunnel, valves on the tanks shall be fitted but control in event of fire may be effected by means of an additional valve on the pipe line or lines outside the tunnel or tunnels. Regulation 70 Fire control plans In any passenger ship, and, as far as applicable in any cargo ship, there shall be permanently exhibited for the guidance of the ship's officers general arrangement plans showing clearly for each deck the control stations, the various fire sections enclosed by fire-resisting bulkheads, the sections enclosed by fire-retarding bulkheads (if any), together with particulars of the fire alarms, detecting systems, the sprinkler installation (if any), the fire extinguishing appliances, means of access to different compartments, decks, &c., and the ventilating system including particulars of the master fan controls, the positions of dampers and identification numbers of the ventilating fans serving each section. Alternatively, at the discretion of the Administration, the aforementioned details may be set out in a booklet, a copy of which shall be supplied to each officer, and one copy at all times shall be available on board in an accessible position. Plans and booklets shall be kept up-to-date, any alterations being recorded thereon as soon as practicable. CHAPTER III LIFE-SAVING APPLIANCES, &c. Regulation 1 Application (a) This Chapter, except where it is otherwise expressly provided, applies as follows to new ships engaged on international voyages: Part A - Passenger ships and cargo ships. Part B - Passenger ships. Part C - Cargo ships. (b) In the case of existing ships engaged on international voyages and which do not already comply with the provisions of this Chapter relating to new ships, the arrangements in each ship shall be considered by the Administration with a view to securing, so far as this is practicable and reasonable, and as early as possible, substantial compliance with the requirements of this Chapter. The proviso to sub-paragraph (b)(i) of Regulation 27 of this Chapter may, however, be applied to existing ships only if: (i) the provisions of Regulations 4, 8, 14, 18 and 19, and paragraphs (a) and (b) of Regulation 27 of this Chapter are complied with; (ii) the liferafts carried in accordance with the provisions of paragraph (b) of Regulation 27 comply with the requirements of either Regulation 15 or Regulation 16, and of Regulation 17 of this Chapter; and (iii) the total number of persons on board shall not be increased as the result of the provision of liferafts. PART A GENERAL (Part A applies to both passenger ships and cargo ships) Regulation 2 Definitions (a) For the purposes of this Chapter the expression "short international voyage" means an international voyage in the course of which a ship is not more than 200 miles from a port or place in which the passengers and crew could be placed in safety, and which does not exceed 600 miles in length between the last port of call in the country in which the voyage begins and the final port of destination. (b) For the purposes of this Chapter, the expression "liferaft" means a liferaft complying with either Regulation 15 or Regulation 16 of this Chapter. (c) For the purposes of this Chapter, the expression "approved launching device" means a device approved by the Administration, capable of launching from the embarkation position a liferaft fully loaded with the number of persons it is permitted to carry and with its equipment. (d) For the purposes of this Chapter, the expression "certificated lifeboatman" means any member of the crew who holds a certificate of efficiency issued under the provisions of Regulation 32 of this Chapter. (e) For the purposes of this Chapter, the expression "buoyant apparatus" means flotation equipment (other than lifeboats, liferafts, lifebuoys and life-jackets) designed to support a specified number of persons who are in the water and of such construction that it retains its shape and properties. Regulation 3 Exemptions (a) The Administration, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of the full requirements of this Chapter unreasonable or unnecessary, may to that extent exempt from the requirements of this Chapter individual ships or classes of ships which, in the course of their voyage, do not go more than 20 miles from the nearest land. (b) In the case of passenger ships engaged on international voyages which are employed in the carriage of large numbers of unberthed passengers in special trades, such, for example, as the pilgrim trade, the Administration, if satisfied that it is impracticable to enforce compliance with the requirements of this Chapter, may exempt such ships from those requirements on the following conditions: (i) that the fullest provision which the circumstances of the trade will permit shall be made in the matter of lifeboats and other life-saving appliances and fire protection; (ii) that all such boats and appliances shall be readily available within the meaning of Regulation 4 of this Chapter; (iii) that a lifejacket shall be provided for every person on board; (iv) that steps shall be taken to formulate general rules which shall be applicable to the particular circumstances of these trades. Such rules shall be formulated in concert with such other Contracting Governments, if any, as may be directly interested in the carriage of such passengers in such trades. Notwithstanding any provisions of the present Convention the Simla Rules, 1931, shall continue in force as between the Parties to those Rules until the rules formulated under sub-paragraph (b)(iv) of this Regulation come into force. Regulation 4 Ready availability of lifeboats, liferafts and buoyant apparatus (a) The general principle governing the provision of lifeboats, liferafts and buoyant apparatus in a ship to which this Chapter applies is that they shall be readily available in case of emergency. (b) To be readily available, the lifeboats, liferafts and buoyant apparatus shall comply with the following conditions: (i) they shall be capable of being put into the water safely and rapidly even under unfavourable conditions of trim and of 15 degrees of list; (ii) it shall be possible to effect embarkation into the lifeboats and liferafts rapidly and in good order; (iii) the arrangement of each lifeboat, liferaft and article of buoyant apparatus shall be such that it will not interfere with the operation of other boats, liferafts and buoyant apparatus. (c) All the life-saving appliances shall be kept in working order and available for immediate use before the ship leaves port and at all times during the voyage. Regulation 5 Construction of lifeboats (a) All lifeboats shall be properly constructed and shall be of such form and proportions that they shall have ample stability in a seaway, and sufficient freeboard when loaded with their full complement of persons and equipment. All lifeboats shall be capable of maintaining positive stability when open to the sea and loaded with their full complement of persons and equipment. (b) (i) All lifeboats shall have rigid sides and internal buoyancy only. The Administration may approve lifeboats with a rigid shelter, provided that it may be readily opened from both inside and outside, and does not impede rapid embarkation and disembarkation or the launching and handling of the lifeboat. (ii) Motor lifeboats may be fitted to the satisfaction of the Administration with means for preventing the entry of water at the fore end. (iii) All lifeboats shall be not less than 24 feet (or 7.3 metres) in length except where owing to the size of the ship, or for other reasons, the Administration considers the carriage of such lifeboats unreasonable or impracticable. In no ship shall the lifeboats be less than 16 feet (or 4.9 metres) in length. (c) No lifeboat may be approved the weight of which when fully laden with persons and equipment exceeds 20 tons (or 20,300 kilograms) or which has a carrying capacity calculated in accordance with Regulation 7 of this Chapter of more than 150 persons. (d) All lifeboats permitted to carry more than 60 persons but not more than 100 persons shall be either motor lifeboats complying with the requirements of Regulation 9 of this Chapter or be lifeboats fitted with an approved means of mechanical propulsion complying with Regulation 10 of this Chapter. All lifeboats permitted to carry more than 100 persons shall be motor lifeboats complying with the requirements of Regulation 9 of this Chapter. (e) All lifeboats shall be of sufficient strength to enable them to be safely lowered into the water when loaded with their full complement of persons and equipment. All lifeboats shall be of such strength that they will not suffer residual deflection if subjected to an overload of 25 per cent. (f) All lifeboats shall have a mean sheer at least equal to 4 per cent of their length. The sheer shall be approximately parabolic in form. (g) In lifeboats permitted to carry 100 or more persons the volume of the buoyancy shall be increased to the satisfaction of the Administration. (h) All lifeboats shall have inherent buoyancy, or shall be fitted with watertight air cases or other equivalent non-corrodible buoyant material which shall not be adversely affected by oil or oil products, sufficient to float the boat and its equipment when the boat is flooded and open to the sea. An additional volume of watertight air cases or other equivalent non-corrodible buoyant material, which shall not be adversely affected by oil or oil products, equal to at least one-tenth of the cubic capacity of the boat shall also be provided. The Administration may permit the watertight air cases to be filled with a non-corrodible buoyant material which shall not be adversely affected by oil or oil products. (i) All thwarts and side-seats shall be fitted as low in the lifeboat as practicable. (j) The block coefficient of the cubic capacity as determined in accordance with Regulation 6 of this Chapter of all lifeboats, except wooden lifeboats made of planks, shall be not less than 0.64. Regulation 6 Cubic capacity of lifeboats (a) The cubic capacity of a lifeboat shall be determined by Stirling's (Simpson's) Rule or by any other method giving the same degree of accuracy. The capacity of a square-sterned lifeboat shall be calculated as if the lifeboat had a pointed stern. (b) For example, the capacity in cubic feet (or cubic metres) of a lifeboat, calculated by the aid of Stirling's Rule, may be considered as given by the following formula: Capacity = L (4A + 2B + 4C) 12 L being the length of the lifeboat in feet (or metres) from the inside of the planking or plating at the stem to the corresponding point at the stern post: in the case of a lifeboat with a square stern, the length is measured to the inside of the transom. A, B, C denote respectively the areas of the cross-sections at the quarter-length forward, amidships, and the quarter-length aft, which correspond to the three points obtained by dividing L into four equal parts. (The areas corresponding to the two ends of the lifeboat are considered negligible.) The areas A, B, C shall be deemed to be given in square feet (or square metres) by the successive application of the following formula to each of the three cross sections: Area = h (a + 4b + 2c + 4d + e) 12 h being the depth measured in feet (or in metres) inside the planking or plating from the keel to the level of the gunwale, or, in certain cases, to a lower level as determined hereafter. a, b, c, d, e denote the horizontal breadths of the lifeboat measured in feet (or in metres) at the upper and lower points of the depth and at the three points obtained by dividing h into four equal parts (a and e being the breadths at the extreme point, and c at the middle point of h). (c) If the sheer of the gunwhale, measured at the two points situated at a quarter of the length of the lifeboat from the ends, exceeds 1 per cent of the length of the lifeboat the depth employed in calculating the area of the cross-sections A or C shall be deemed to be the depth amidships plus 1 per cent of the length of the lifeboat. (d) If the depth of the lifeboat amidships exceeds 45 per cent of the breadth, the depth employed in calculating the area of the amidship cross-section B shall be deemed to be equal to 45 per cent of the breadth, and the depth employed in calculating the areas of the quarter-length sections A and C is obtained by increasing this last figure by an amount equal to 1 per cent of the length of the lifeboat, provided that in no case shall the depths employed in the calculation exceed the actual depths at these points. (e) If the depth of the lifeboat is greater than 4 feet (or 122 centimetres) the number of persons given by the application of this Rule shall be reduced in proportion to the ratio of 4 feet (or 122 centimetres) to the actual depth, until the lifeboat has been satisfactorily tested afloat with that number of persons on board, all wearing lifejackets. (f) The Administration shall impose, by suitable formulae, a limit for the number of persons allowed in lifeboats with very fine ends and in lifeboats very full in form. (g) The Administration may assign to a lifeboat constructed of wooden planks capacity equal to the product of the length, the breadth and the depth multiplied by 0.6 if it is evident that this formula does not give a greater capacity than that obtained by the above method. The dimensions shall then be measured in the following manner: Length. - From the intersection of the outside of the planking with the stem to the corresponding point at the stern post or, in the case of a square-sterned boat, to the after side of the transom. Breadth. - From the outside of the planking at the point where the breadth of the boat is greatest. Depth. - Amidships inside the planking from the keel to the level of the gunwale, but the depth used in calculating the cubic capacity may not in any case exceed 45 per cent of the breadth. In all cases the shipowner has the right to require that the cubic capacity of the lifeboat shall be determined by exact measurement. (h) The cubic capacity of a motor lifeboat or a lifeboat fitted with other propelling gear shall be obtained from the gross capacity by deducting a volume equal to that occupied by the motor and its accessories or the gearbox of the other propelling gear, and, when carried, the radiotelegraph installation and searchlight with their accessories. Regulation 7 Carrying capacity of lifeboats The number of persons which a lifeboat shall be permitted to accommodate shall be equal to the greatest whole number obtained by dividing the capacity in cubic feet by:
provided that the number shall in no case exceed the number of adult persons wearing lifejackets which can be seated without in any way interfering with the use of oars or the operation of other propulsion equipment. Regulation 8 Number of motor lifeboats to be carried (a) In every passenger ship there shall be carried on each side of the ship at least one motor lifeboat complying with the requirements of Regulation 9 of this Chapter. Provided that in passenger ships in which the total number of persons which the ship is certified to carry, together with the crew, does not exceed 30, only one such motor lifeboat shall be required. (b) In every cargo ship of 1,600 tons gross tonnage and upwards, except tankers, ships employed as whale factory ships, ships employed as fish processing or canning factory ships, and ships engaged in the carriage of persons in the whaling, fish processing or canning industries, there shall be carried at least one motor lifeboat complying with the requirements of Regulation 9 of this Chapter. (c) In every tanker of 1,600 tons gross tonnage and upwards, in every ship employed as a whale factory ship, in every ship employed as a fish processing or canning factory ship and in every ship engaged in the carriage of persons employed in the whaling, fish processing or canning industries, there shall be carried on each side at least one motor lifeboat complying with the requirements of Regulation 9 of this Chapter. Regulation 9 Specification of motor lifeboats (a) A motor lifeboat shall comply with the following conditions: (i) It shall be fitted with a compression ignition engine and kept so as to be at all times ready for use; it shall be capable of being readily started in all conditions; sufficient fuel for 24 hours continuous operation at the speed specified in sub-paragraph (a)(iii) of this Regulation shall be provided. (ii) The engine and its accessories shall be suitably enclosed to ensure operation under adverse weather conditions, and the engine casing shall be fire-resisting.

(2) In the case of any other motor lifeboat, at least four knots. (b) The volume of the internal buoyancy appliances of a motor lifeboat shall be increased above that required by Regulation 5 of this Chapter by the amount, if any, by which the volume of the internal buoyancy appliances required to support the engine and its accessories, and, if fitted, the searchlight and radiotelegraph installation and their accessories, exceeds the volume of the internal buoyancy appliances required, at the rate of one cubic foot (0.0283 cubic metre) per person, to support the additional persons which the lifeboat could accommodate if the motor and its accessories, and, if fitted, the searchlight and radiotelegraph installation and their accessories, were removed. Regulation 10 Specification of mechanically propelled lifeboats other than motor lifeboats A mechanically propelled lifeboat, other than a motor lifeboat, shall comply with the following conditions: (a) The propelling gear shall be of an approved type and shall have sufficient power to enable the lifeboat to be readily cleared from the ship's side when launched and to be able to hold course under adverse weather conditions. If the gear is manually operated it shall be capable of being worked by persons untrained in its use and shall be capable of being operated when the lifeboat is flooded. (b) A device shall be fitted by means of which the helmsman can cause the lifeboat to go astern at any time when the propelling gear is in operation. (c) The volume of the internal buoyancy of a mechanically propelled lifeboat, other than a motor lifeboat, shall be increased to compensate for the weight of the propelling gear. Regulation 11 Equipment of lifeboats (a) The normal equipment of every lifeboat shall consist of: (i) a single banked complement of buoyant oars, two spare buoyant oars, and a buoyant steering oar; one set and a half of thole pins or crutches, attached to the lifeboat by lanyard or chain; a boat hook; (ii) two plugs for each plug hole (plugs are not required when proper automatic valves are fitted) attached to the lifeboat by lanyards or chains; a baler, and two buckets of approved material; (iii) a rudder attached to the lifeboat and a tiller; (iv) two hatchets, one at each end of the lifeboat; (v) a lamp, with oil sufficient for 12 hours; two boxes of suitable matches in a watertight container; (vi) a mast or masts, with galvanised wire stays together with sails (coloured orange); (vii) an efficient compass in binnacle, to be luminised or fitted with suitable means of illumination; (viii) a lifeline becketed round the outside of the lifeboat; (ix) a sea-anchor of approved size; (x) two painters of sufficient length. One shall be secured to the forward end of the lifeboat with strop and toggle so that it can be released, and the other shall be firmly secured to the stem of the lifeboat and be ready for use; (xi) a vessel containing one gallon (or four and a half litres) of vegetable, fish or animal oil. The vessel shall be so constructed that the oil can be easily distributed on the water, and so arranged that it can be attached to the sea-anchor; (xii) a food ration, determined by the Administration, for each person the lifeboat is certified to carry. These rations shall be kept in airtight receptacles which are to be stowed in a watertight container; (xiii) watertight receptacles containing six pints (or three litres) of fresh water for each person the lifeboat is certified to carry, or watertight receptacles containing four pints (or two litres) of fresh water for each person together with an approved de-salting apparatus capable of providing two pints (or one litre) of drinking water per person; a rustproof dipper with lanyard; a rustproof graduated drinking vessel; (xiv) four parachute signals of approved type capable of giving a bright red light at a high altitude; six hand flares of an approved type giving a bright red light; (xv) two buoyant smoke signals of an approved type (for day-time use) capable of giving off a volume of orange-coloured smoke; (xvi) approved means to enable persons to cling to the boat should it be upturned, in the form of bilge keels or keel rails, together with grab lines secured from gunwale to gunwale under the keel, or other approved arrangements; (xvii) an approved first aid outfit in a watertight case; (xviii) a waterproof electric torch suitable for signalling in the Morse Code together with one spare set of batteries and one spare bulb in a waterproof container; (xix) a daylight-signalling mirror of an approved type; (xx) a jack-knife fitted with a tin opener to be kept attached to the boat with a lanyard; (xxi) two light buoyant heaving lines; (xxii) a manual pump of an approved type; (xxiii) a suitable locker for stowage of small items of equipment; (xxiv) one whistle or equivalent sound signal; (xxv) one set of fishing tackle; (xxvi) one approved cover of a highly visible colour capable of protecting the occupants against injury by exposure; and (xxvii) one copy of the illustrated table of life-saving signals referred to in Regulation 16 of Chapter V. (b) In the case of ships engaged on voyages of such duration that in the opinion of the Administration the items specified in sub-paragraphs (vi), (xii), (xix), (xx) and (xxv) of paragraph (a) of this Regulation are unnecessary, the Administration may allow them to be dispensed with. (c) Notwithstanding the provisions of paragraph (a) of this Regulation, motor lifeboats or other approved mechanically propelled lifeboats need not carry a mast or sails or more than half the complement of oars, but they shall carry two boat hooks. (d) All lifeboats shall be fitted with suitable means to enable persons in the water to climb into the lifeboat. (e) Every motor lifeboat shall carry portable fire-extinguishing equipment of an approved type capable of discharging froth or other suitable substance for extinguishing oil fires. Regulation 12 Security of lifeboat equipment All items of lifeboat equipment, with the exception of the boat hook which shall be kept free for fending off purposes, shall be suitably secured within the lifeboat. The lashing shall be carried out in such a manner as to ensure the security of the equipment and so as not to interfere with the lifting hooks or to prevent ready embarkation. All items of lifeboat equipment shall be as small and light in weight as possible and shall be packed in suitable and compact form. Regulation 13 Portable radio apparatus for survival craft (a) An approved portable radio apparatus for survival craft complying with the requirements set out in Regulation 13 of Chapter IV shall be carried in all ships except those on which there is carried on each side of the ship a motor lifeboat fitted with a radiotelegraph installation complying with the provisions of Regulation 14 of this Chapter and of Regulation 12 of Chapter IV. All this equipment shall be kept together in the chartroom or other suitable place ready to be moved to one or other of the lifeboats in the event of an emergency. However, in tankers of 3,000 tons gross tonnage and upwards in which lifeboats are fitted amidships and aft this equipment shall be kept in a suitable place in the vicinity of those lifeboats which are furthest away from the ship's main transmitter. (b) In the case of ships engaged on voyages of such duration that in the opinion of the Administration portable radio apparatus for survival craft is unnecessary, the Administration may allow such equipment to be dispensed with. Regulation 14 Radio apparatus and searchlights in motor lifeboats (a) (i) Where the total number of persons on board a passenger ship engaged on international voyages which are not short international voyages, a ship employed as a whale factory ship, a ship employed as a fish processing or canning factory ship or a ship engaged in the carriage of persons employed in the whaling, fish processing or canning industries, is more than 199 but less than 1,500, a radiotelegraph apparatus complying with the requirements set out in this Regulation and in Regulation 12 of Chapter IV shall be fitted in at least one of the motor lifeboats required under Regulation 8 of this Chapter to be carried in that ship. (ii) Where the total number of persons on board such a ship is 1,500 or more, such a radiotelegraph apparatus shall be fitted in every motor lifeboat required under Regulation 8 of this Chapter to be carried in that ship. (b) The radio apparatus shall be installed in a cabin large enough to accommodate both the equipment and the persons using it. (c) The arrangements shall be such that the efficient operation of the transmitter and receiver shall not be interfered with by the engine while it is running, whether a battery is on charge or not. (d) The radio battery shall not be used to supply power to any engine starting motor or ignition system. (e) The motor lifeboat engine shall be fitted with a dynamo for recharging the radio battery, and for other services. (f) A searchlight shall be fitted in each motor lifeboat required to be carried under paragraph (a) of Regulation 8 of this Chapter in passenger ships and under paragraph (c) of that Regulation in ships employed as whale factory ships, fish processing or canning factory ships and ships engaged in the carriage of persons employed in the whaling, fish processing or canning industries. (g) The searchlight shall include a lamp of at least 80 watts, an efficient reflector and a source of power which will give effective illumination of a light-coloured object having a width of about 60 feet (or 18 metres) at a distance of 200 yards (or 180 metres) for a total period of six hours and shall be capable of working for at least three hours continuously. Regulation 15 Requirements for inflatable liferafts (a) Every inflatable liferaft shall be so constructed that, when fully inflated and floating with the cover uppermost, it shall be stable in a seaway. (b) The liferaft shall be so constructed that if it is dropped into the water from a height of 60 feet (or 18 metres) neither the liferaft nor its equipment will be damaged. (c) The construction of the liferaft shall include a cover which shall automatically be set in place when the liferaft is inflated. This cover shall be capable of protecting the occupants against injury from exposure, and means shall be provided for collecting rain. The top of the cover shall be fitted with a lamp which derives its luminosity from a sea-activated cell and a similar lamp shall also be fitted inside the liferaft. The cover of the liferaft shall be of a highly visible colour. (d) The liferaft shall be fitted with a painter and shall have a line securely becketed round the outside. A lifeline shall also be fitted around the inside of the liferaft. (e) The liferaft shall be capable of being readily righted by one person if it inflates in an inverted position. (f) The liferaft shall be fitted at each opening with efficient means to enable persons in the water to climb on board. (g) The liferaft shall be contained in a valise or other container so constructed as to be capable of withstanding hard wear under conditions met with at sea. The liferaft in its valise or other container shall be inherently buoyant. (h) The buoyancy of the liferaft shall be so arranged as to ensure by a division into an even number of separate compartments, half of which shall be capable of supporting out of the water the number of persons which the liferaft is permitted to accommodate, or by some other equally efficient means, that there is a reasonable margin of buoyancy if the raft is damaged or partially fails to inflate.

These boats shall be of an approved type and shall be not more than 28 feet (or 81/2 metres) in length. They may be counted for the purposes of paragraphs (b) and (c) of this Regulation, provided that they .comply fully with the requirements for lifeboats of this Chapter, and for the purposes of Regulation 8 provided that in addition they comply fully with the requirements of Regulation 9 and where appropriate Regulation 14. They shall be kept ready for immediate use while the ship is at sea. In ships in which the requirements of paragraph (h) of Regulation 29 are met by means of appliances fitted to the sides of the lifeboats, such appliances shall not be required to be fitted to the two boats provided to meet the requirements of this Regulation. (b) Passenger ships engaged on international voyages which are not short international voyages shall carry: (i) Lifeboats on each side of such aggregate capacity as will accommodate half the total number of persons on board. Provided that the Administration may permit the substitution of lifeboats by liferafts of the same total capacity so however that there shall never be less than sufficient lifeboats on each side of the ship to accommodate 371/2 per cent of all on board. (ii) Liferafts of sufficient aggregate capacity to accommodate 25 per cent of the total number of persons on board, together with buoyant apparatus for 3 per cent of that number. Provided that ships which have a factor of subdivision of 0.33 or less shall be permitted to carry, in lieu of liferafts for 25 per cent of all on board and buoyant apparatus for 3 per cent of all on board, buoyant apparatus for 25 per cent of that number. (c) (i) A passenger ship engaged on short international voyages shall be provided with sets of davits in accordance with its length as specified in Column A of the Table in Regulation 28 of this Chapter. Each set of davits shall have a lifeboat attached to it and these lifeboats shall provide at least the minimum capacity required by Column C of the Table or the capacity required to provide accommodation for all on board if this is less. Provided that when in the opinion of the Administration it is impracticable or unreasonable to place on a ship engaged on short international voyages the number of sets of davits required by Column A of the Table in Regulation 28, the Administration may authorise, under exceptional conditions, a smaller number of davits, except that this number shall never be less than the minimum number fixed by Column B of the Table, and that the total capacity of the lifeboats on the ship will be at least equal to the minimum capacity required by Column C or the capacity required to provide for all persons on board if this is less. (ii) If the lifeboats so provided are not sufficient to accommodate all on board, additional lifeboats under davits or liferafts shall be provided so that the accommodation provided in the lifeboats and the liferafts in the ship shall be sufficient for all on board. (iii) Notwithstanding the provisions of sub-paragraph (c)(ii) in any ship engaged on short international voyages the number of persons carried shall not exceed the total capacity of the lifeboats provided in accordance with sub-paragraphs (c)(i) and (c)(ii) of this Regulation unless the Administration considers that this is necessitated by the volume of traffic and then only if the ship complies with the provisions of paragraph (d) of Regulation 1 of Chapter II. (iv) Where under the provisions of sub-paragraph (c)(iii) the Administration has permitted the carriage of persons in excess of the lifeboat capacity and is satisfied that it is impracticable in that ship to stow the liferafts carried in accordance with sub-paragraph (c)(ii) it may permit a reduction in the number of lifeboats. Provided that: (1) the number of lifeboats shall, in the case of ships of 190 feet (or 58 metres) in length and over, never be less than four, two of which shall be carried on each side of the ship, and in the case of ships of less than 190 feet (or 58 metres) in length, shall never be less than two, one of which shall be carried on each side of the ship; and (2) the number of lifeboats and liferafts shall always be sufficient to accommodate the total number of persons on board. (v) Every passenger ship engaged on short international voyages shall carry in addition to the lifeboats and liferafts required by the provisions of this paragraph, liferafts sufficient to accommodate 10 per cent of the total number of persons for whom there is accommodation in the lifeboats carried in that ship. (vi) Every passenger ship engaged on short international voyages shall also carry buoyant apparatus for at least 5 per cent of the total number of persons on board. (vii) The Administration may permit individual ships or classes of ships with short international voyage certificates to proceed on voyages in excess of 600 miles but not exceeding 1,200 miles if such ships comply with the provisions of paragraph (d) of Regulation 1 of Chapter II, if they carry lifeboats which provide for 75 per cent of the persons on board and otherwise comply with the provisions of this paragraph. Regulation 28 Table relating to davits and lifeboat capacity for ships on short international voyages The following table fixes according to the length of the ship: (A) the minimum number of sets of davits to be provided on a ship engaged on short international voyages to each of which must be attached a lifeboat in accordance with Regulation 27 of this Chapter; (B) the smaller number of sets of davits which may be authorised exceptionally on a ship engaged on short international voyages under Regulation 27; and (C) the minimum lifeboat capacity required for a ship engaged on short international voyages.
Note on (C). - Where the length of the ship is under 100 feet (or 31 metres) or over 550 feet (or 168 metres) the minimum number of sets of davits and the cubic capacity of the lifeboats shall be prescribed by the Administration. Regulation 29 Stowage and handling of lifeboats, liferafts and buoyant apparatus (a) Lifeboats and liferafts shall be stowed to the satisfaction of the Administration in such a way that: (i) they can all be launched in the shortest possible time and in not more than 30 minutes; (ii) they will not impede in any way the prompt handling of any of the other lifeboats, liferafts or buoyant apparatus or the marshalling of the persons on board at the launching stations, or their embarkation; (iii) the lifeboats, and the liferafts for which approved launching devices are required to be carried, shall be capable of being put into the water loaded with their full complement of persons and equipment even in unfavourable conditions of trim and of 15 degrees of list either way; and (iv) the liferafts for which approved launching devices are not required to be carried, and the buoyant apparatus, shall be capable of being put into the water even in unfavourable conditions of trim and of 15 degrees of list either way.

Exceptionally, the Administration may allow manila rope falls or falls of another approved material with or without winches (except that the emergency boats shall be required to be served by winches which are capable of quick recovery of those boats) where they are satisfied that manila rope falls or falls of another approved material are adequate. (k) At least two lifelines shall be fitted to the davit span, and the falls and lifelines shall be long enough to reach the water with the ship at its lightest sea-going draught and listed to 15 degrees either way. Lower fall blocks shall be fitted with a suitable ring or long link for attaching to the sling hooks unless an approved type of disengaging gear is fitted. (l) Where mechanically-powered appliances are fitted for the recovery of the lifeboats, efficient hand gear shall also be provided. Where davits are recovered by action of the falls by power, safety devices shall be fitted which will automatically cut off the power before the davits come against the stops in order to avoid overstressing the wire rope falls or davits. (m) Lifeboats attached to davits shall have the falls ready for service and arrangements shall be made for speedily, but not necessarily simultaneously, detaching the lifeboats from the falls. The point of attachment of the lifeboats to the falls shall be at such height above the gunwale as to ensure stability when lowering the lifeboats.

(vi) It shall be fitted with a painter and have a line securely becketed round the outside. (b) The number of persons for which buoyant apparatus is certified shall be the number, (i) ascertained by dividing the number of pounds of iron which it is capable of supporting in fresh water by 32 (or the number of kilograms divided by 14.5), or (ii) equal to the number of feet (equivalent to 30.5 centimetres) in the perimeter, whichever is the less.
Regulation 34 Number of lifebuoys to be provided The minimum numbers of lifebuoys with which passenger ships are provided shall be fixed by the following table:
PART C CARGO SHIPS ONLY Regulation 35 Number and capacity of lifeboats and liferafts (a) (i) Every cargo ship, except tankers of 1,600 tons gross tonnage and upwards, ships employed as whale factory ships, fish processing or canning factory ships, and ships engaged in the carriage of persons employed in the whaling, fish processing or canning industries, shall carry lifeboats on each side of the ship of such aggregate capacity as will accommodate all persons on board, and in addition shall carry liferafts sufficient to accommodate half that number. Provided that, in the case of such cargo ships engaged on international voyages between near neighbouring countries, the Administration, if it is satisfied that the conditions of the voyage are such as to render the compulsory carriage of liferafts unreasonable or unnecessary, may to that extent exempt individual ships or classes of ships from this requirement. (ii) Every tanker of 1,600 tons gross tonnage and upwards shall carry lifeboats on each side of the ship of such aggregate capacity as will accommodate all persons on board. (b) (i) Every ship employed as a whale factory ship, every ship employed as a fish processing or canning factory ship and every ship engaged in the carriage of persons employed in the whaling, fish processing or canning industries shall carry: (1) Lifeboats on each side of such aggregate capacity as will accommodate half the total number of persons on board. Provided that the Administration may permit the substitution of lifeboats by liferafts at the same total capacity so however that there shall never be less than sufficient lifeboats on each side of the ship to accommodate 371/2 per cent of all on board. (2) Liferafts of sufficient aggregate capacity to accommodate half the total number of persons on board. Provided that, if in ships employed as fish processing or canning factory ships, it is impracticable to carry lifeboats which comply fully with the requirements of this Chapter, the Administration may permit instead the carriage of other boats, which shall however provide not less than the accommodation required by this Regulation and shall have at least the buoyancy and equipment required by this Chapter for lifeboats. (ii) Every ship employed as a whale factory ship, every ship employed as a fish processing or canning factory ship and every ship engaged in the carriage of persons employed in the whaling, fish processing or canning industries shall carry two boats - one on each side - for use in an emergency. These boats shall be of an approved type and shall be not more than 28 feet (or 81/2 metres) in length. They may be counted for the purposes of this paragraph provided that they comply fully with the requirements for lifeboats of this Chapter and for the purposes of Regulation 8 provided that in addition they comply with the requirements of Regulation 9, and, where appropriate, Regulation 14. They shall be kept ready for immediate use while the ship is at sea. In ships in which the requirements of paragraph (g) of Regulation 36 are met by means of appliances fitted to the sides of the lifeboats, such appliances shall not be required to be fitted to the two boats provided to meet the requirements of this Regulation. (c) Every tanker of 3,000 tons gross tonnage and upwards shall carry not less than four lifeboats. Two lifeboats shall be carried aft and two amidships, except that in tankers which have no amidships superstructure all lifeboats shall be carried aft. Provided that, if in the case of tankers with no amidships superstructure it is impracticable to carry four lifeboats aft, the Administration may permit instead the carriage aft of one lifeboat on each side of the ship. In such a case: (i) each such lifeboat shall not exceed 26 feet (or 8 metres) in length; (ii) each such lifeboat shall be stowed as far forward as practicable, but at least so far forward that the after end of the lifeboat is one-and-a-half times the length of the lifeboat forward of the propeller; (iii) each lifeboat shall be stowed as near the sea level as is safe and practicable; and (iv) there shall be carried in addition liferafts sufficient to accommodate at least one-half of the total number of persons on board. Regulation 36 Davits and launching arrangements (a) In cargo ships lifeboats and liferafts shall be stowed to the satisfaction of the Administration. (b) Every lifeboat shall be attached to a separate set of davits. (c) Lifeboats, and liferafts for which approved launching devices are required to be carried, shall not be placed in the bow of the ship. They shall be stowed in such positions as to ensure safe launching, having particular regard to clearance from the propeller and steeply overhanging portions of the hull aft, with the object of ensuring so far as practicable that they are capable of being launched down the straight side of the ship. (d) Davits shall be of approved design and shall be suitably placed to the satisfaction of the Administration. (e) In tankers of 1,600 tons gross tonnage and upwards, ships employed as whale factory ships, ships employed as fish processing or canning factory ships and ships engaged in the carriage of persons employed in the whaling, fish processing or canning industries, all davits shall be of the gravity type. In other ships, davits shall be as follows: (i) luffing or gravity type for operating lifeboats weighing not more than 21/4 tons (or 2,300 kilograms) in their turning out condition; (ii) gravity type for operating lifeboats weighing more than 21/4 tons (or 2,300 kilograms) in their turning out condition. (f) Davits, falls, blocks and all other gear shall be of such strength that the lifeboats can be turned out manned by a launching crew and then safely lowered with the full complement of persons and equipment, with the ship listed to 15 degrees either way, and with a 10 degrees trim. (g) Skates or other suitable means shall be provided to facilitate launching the lifeboats against a list of 15 degrees. (h) Means shall be provided for bringing the lifeboats against the ship's side and there holding them so that persons may be safely embarked. (i) Lifeboats, together with the emergency boats required by sub-paragraph (b)(ii) of Regulation 35 of this Chapter, shall be served by wire rope falls, together with winches of an approved type which, in the case of the emergency boats, shall be capable of quick recovery of those boats. Exceptionally, the Administration may allow manila rope falls or falls of another approved material with or without winches (except that the emergency boats shall be required to be served by winches which are capable of quick recovery of those boats) where they are satisfied that manila rope falls or falls of another approved material are adequate. (j) At least two lifelines shall be fitted to the davit spans, and the falls and lifelines shall be long enough to reach the water with the ship at its lightest sea-going draught and listed to 15 degrees either way. Lower fall blocks shall be fitted with a suitable ring or long link for attaching to the sling hooks unless an approved type of disengaging gear is fitted. (k) Where mechanically powered appliances are fitted for the recovery of the lifeboats, efficient hand gear shall also be provided. Where davits are recovered by action of the falls by power, safety devices shall be fitted which will automatically cut off the power before the davits come against the stops in order to avoid overstressing the wire rope falls or davits. (l) Lifeboats shall have the falls ready for service, and arrangements shall be made for speedily, but not necessarily simultaneously, detaching the lifeboats from the falls. The point of attachment of the lifeboats to the falls shall be at such height above the gunwale as to ensure stability when lowering the lifeboats. (m) In ships employed as whale factory ships, ships employed as fish processing or canning factory ships and ships engaged in the carriage of persons employed in the whaling, fish processing or canned industries, in which there are carried lifeboats and liferafts in accordance with sub-paragraph (i)(2) of paragraph (b) of Regulation 35 no approved launching devices need be provided for the liferafts, but there shall be provided such devices sufficient in number, in the opinion of the Administration, to enable the liferafts carried in accordance with sub-paragraph (i)(1) of that paragraph to be put into the water loaded with the number of persons they are permitted to accommodate, in not more than 30 minutes in calm conditions. Approved launching devices so provided shall, so far as practicable, be distributed equally on each side of the ship. Every liferaft carried on ships in which an approved launching device is required to be provided shall be of a type which is capable of being launched by such a device. Regulation 37 Number of lifebuoys to be provided At least eight lifebuoys of a type which satisfies the requirements of Regulation 21 of this Chapter shall be carried. Regulation 38 Emergency lighting The lighting required by sub-paragraphs (a)(ii), (b)(ii) and (b)(iii) of Regulation 19 of this Chapter shall be capable of being supplied for at least three hours by the emergency source of power required by Regulation 26 of Chapter II. In cargo ships of 1,600 tons gross tonnage and upwards the Administration shall ensure that the lighting of the alleyways, stairways and exits is such that the access of all persons on board to the launching stations and stowage positions of lifeboats and liferafts is not impeded. CHAPTER IV RADIOTELEGRAPHY AND RADIOTELEPHONY PART A APPLICATION AND DEFINITIONS Regulation 1 Application (a) Unless expressly provided otherwise, this Chapter applies to all ships to which the present Regulations apply. (b) This Chapter does not apply to ships to which the present Regulations would otherwise apply while such ships are being navigated within the Great Lakes of North America and their connecting and tributary waters as far east as the lower exit of the St. Lambert Lock at Montreal in the Province of Quebec, Canada.[6] (c) No provision in this Chapter shall prevent the use by a ship or survival craft in distress of any means at its disposal to attract attention, make known its position and obtain help. Regulation 2 Terms and definitions For the purpose of this Chapter the following terms shall have the meanings defined below. All other terms which are used in this Chapter and which are also defined in the Radio Regulations shall have the same meanings as defined in those Regulations: (a) "Radio Regulations" means the Radio Regulations annexed to, or regarded as being annexed to, the most recent International Telecommunication Convention which may be in force at any time. (b) "Radiotelegraph auto alarm" means an automatic alarm receiving apparatus which responds to the radiotelegraph alarm signal and has been approved. (c) "Radio officer" means a person holding at least a first or second class radiotelegraph operator's certificate complying with the provisions of the Radio Regulations, who is employed in the radiotelegraph station of a ship which is provided with such a station in compliance with the provisions of Regulation 3 or Regulation 4 of this Chapter. (d) "Radiotelephone operator" means a person holding an appropriate certificate complying with the provisions of the Radio Regulations. (e) "Existing installation" means: (i) an installation wholly installed on board a ship before the date on which the present Convention comes into force, irrespective of the date on which acceptance by the respective Administration takes effect; and (ii) an installation part of which was installed on board a ship before the date of coming into force of the present Convention and the rest of which consists either of parts installed in replacement of identical parts, or parts which comply with the requirements of this Chapter. (f) "New installation" means any installation which is not an existing installation. Regulation 3 Radiotelegraph station Passenger ships irrespective of size and cargo ships of 1,600 tons gross tonnage and upwards, unless exempted under Regulation 5 of this Chapter, shall be fitted with a radiotelegraph station complying with the provisions of Regulations 8 and 9 of this Chapter. Regulation 4 Radiotelephone station Cargo ships of 300 tons gross tonnage and upwards but less than 1,600 tons gross tonnage, unless fitted with a radiotelegraph station complying with the provisions of Regulations 8 and 9 of this Chapter shall, provided they are not exempted under Regulation 5 of this Chapter, be fitted with a radiotelephone station complying with the provisions of Regulations 14 and 15 of this Chapter. Regulation 5 Exemptions from Regulations 3 and 4 (a) The Contracting Governments consider it highly desirable not to deviate from the application of Regulations 3 and 4 of this Chapter; nevertheless the Administration may grant to individual passenger or cargo ships exemptions of a partial and/or conditional nature, or complete exemption from the requirements of Regulation 3 or Regulation 4 of this Chapter. (b) The exemptions permitted under paragraph (a) of this Regulation shall be granted only to a ship engaged on a voyage where the maximum distance of the ship from the shore, the length of the voyage, the absence of general navigational hazards, and other conditions affecting safety are such as to render the full application of Regulation 3 or Regulation 4 of this Chapter unreasonable or unnecessary. When deciding whether or not to grant exemptions to individual ships, Administrations shall have regard to the effect that exemptions may have upon the general efficiency of the distress service for the safety of all ships. Administrations should bear in mind the desirability of requiring ships which are exempted from the requirement of Regulation 3 of this Chapter to be fitted with a radiotelephone station which complies with the provisions of Regulations 14 and 15 of this Chapter as a condition of exemption. (c) Each Administration shall submit to the Organization as soon as possible after the first of January in each year a report showing all exemptions granted under paragraphs (a) and (b) of this Regulation during the previous calendar year and giving the reasons for granting such exemptions. PART B WATCHES Regulation 6 Watches - radiotelegraph (a) Each ship which in accordance with Regulation 3 or Regulation 4 of this Chapter is fitted with a radiotelegraph station shall, while at sea, carry at least one radio officer and, if not fitted with a radiotelegraph auto alarm, shall, subject to the provisions of paragraph (d) of this Regulation, listen continuously on the radiotelegraph distress frequency by means of a radio officer using headphones or a loud-speaker. (b) Each passenger ship which in accordance with Regulation 3 of this Chapter is fitted with a radiotelegraph station, if fitted with a radiotelegraph auto alarm, shall, subject to the provisions of paragraph (d) of this Regulation, and while at sea, listen on the radiotelegraph distress frequency by means of a radio officer using headphones or a loud-speaker, as follows: (i) if carrying or certificated to carry 250 passengers or less, at least 8 hours listening a day in the aggregate; (ii) if carrying or certificated to carry more than 250 passengers and engaged on a voyage exceeding 16 hours duration between two consecutive ports, at least 16 hours listening a day in the aggregate. In this case the ship shall carry at least two radio officers; (iii) if carrying or certificated to carry more than 250 passengers and engaged on a voyage of less than 16 hours duration between two consecutive ports, at least 8 hours listening a day in the aggregate. (c) (i) Each cargo ship which in accordance with Regulation 3 of this Chapter is fitted with a radiotelegraph station, if fitted with a radiotelegraph auto alarm, shall, subject to the provisions of paragraph (d) of this Regulation, and while at sea, listen on the radiotelegraph distress frequency by means of a radio officer using headphones or a loud-speaker, for at least 8 hours a day in the aggregate. However, Administrations may on cargo ships of 1,600 tons gross tonnage and upwards but less than 3,500 tons gross tonnage permit the hours of listening to be limited to not less than 2 hours a day in the aggregate for a period of three years from the date of coming into force of the present Convention. (ii) Each cargo ship of 300 tons gross tonnage and upwards but less than 1,600 tons gross tonnage which is fitted with a radiotelegraph station as a consequence of Regulation 4 of this Chapter, if fitted with a radiotelegraph auto alarm shall, subject to the provisions of paragraph (d) of this Regulation, and while at sea, listen on the radiotelegraph distress frequency by means of a radio officer using headphones or a loud-speaker, during such periods as may be determined by the Administration. Administrations shall, however, have regard to the desirability of requiring, whenever practicable, a listening watch of at least 8 hours a day in the aggregate. (d) During the period when a radio officer is required by this Regulation to listen on the radiotelegraph distress frequency the radio officer may discontinue such listening during the time when he is handling traffic on other frequencies, or performing other essential radio duties, but only if it is impracticable to listen by split headphones or loud-speaker. The listening watch shall always be maintained by a radio officer using headphones or loud-speaker during the silence periods provided for by the Radio Regulations. (e) In all ships fitted with a radiotelegraph auto alarm this radiotelegraph auto alarm shall, while the ship is at sea, be in operation whenever there is no listening being kept under paragraphs (b), (c) or (d) of this Regulation and, wherever practicable, during direction-finding operations. (f) The listening periods provided for by this Regulation, including those which are determined by the Administration, should be maintained preferably during periods prescribed for the radiotelegraph service by the Radio Regulations. Regulation 7 Watches - radiotelephone (a) Each ship which is fitted with a radiotelephone station in accordance with Regulation 4 of this Chapter shall, for safety purposes, carry at least one radiotelephone operator (who may be the master, an officer or a member of the crew holding only a certificate for radiotelephony) and shall, subject to the provisions of paragraph (b) of this Regulation, while at sea, maintain continuous listening watch on the radiotelephone distress frequency, in the place on board from which the ship is usually navigated, using a loud-speaker or other appropriate means. (b) Listening may be discontinued (i) when the receiving equipment is being used for traffic on another frequency and a second receiver is not available; or (ii) when, in the opinion of the master, conditions are such that maintenance of the listening watch would interfere with the safe navigation of the ship. Listening watch should, however, as far as possible be maintained during the silence periods provided for in the Radio Regulations. PART C TECHNICAL REQUIREMENTS Regulation 8 Radiotelegraph stations (a) The radiotelegraph station shall be so located that no harmful interference from extraneous mechanical or other noise will be caused to the proper reception of radio signals. The station shall be placed as high in the ship as is practicable, so that the greatest possible degree of safety may be secured.

Regulation 9 Radiotelegraph installations (a) Except as otherwise expressly provided in this Regulation: (i) The radiotelegraph station shall include a main installation and a reserve installation, electrically separate and electrically independent of each other. (ii) The main installation shall include a main transmitter, main receiver and main source of energy. (iii) The reserve installation shall include a reserve transmitter, reserve receiver and reserve source of energy. (iv) A main and a reserve aerial shall be provided and installed, provided that the Administration may except any ship from the provision of a reserve aerial if it is satisfied that the fitting of such an aerial is impracticable or unreasonable, but in such case a suitable spare aerial completely assembled for immediate installation shall be carried. In addition, sufficient aerial wire and insulators shall in all cases be provided to enable a suitable aerial to be erected. The main aerial, if suspended between supports liable to whipping, shall be suitably protected against breakage. (b) In installations on cargo ships (except those on cargo ships of 1,600 tons gross tonnage and upwards installed on or after 19 November 1952), if the main transmitter complies with all the requirements for the reserve transmitter, the latter is not obligatory. (c) (i) The main and reserve transmitters shall be capable of being quickly connected with and tuned to the main aerial, and the reserve aerial if one is fitted. (ii) The main and reserve receivers shall be capable of being quickly connected with any aerial with which they are required to be used. (d) All parts of the reserve installation shall be placed as high in the ship as is practicable, so that the greatest possible degree of safety may be secured. (e) The main and reserve transmitters shall be capable of transmitting on the radiotelegraph distress frequency using a class of emission assigned by the Radio Regulations for that frequency. In addition, the main transmitter shall be capable of transmitting on at least two of the frequencies, and of using a class of emission, which, in accordance with the Radio Regulations, may be used for the transmission of safety messages in the bands between 405 kc/s and 535 kc/s. The reserve transmitter may consist of a ship's emergency transmitter, as defined in, and limited in use by, the Radio Regulations. (f) The main and reserve transmitters shall, if modulated emission is prescribed by the Radio Regulations, have a depth of modulation of not less than 70 per cent and a note frequency between 450 and 1,350 cycles per second. (g) The main and reserve transmitters shall, when connected to the main aerial, have a minimum normal range as specified below, that is to say, they must be capable of transmitting clearly perceptible signals from ship to ship by day and under normal conditions and circumstances over the specified ranges.[7
This figure represents the product of the maximum height of the aerial above the deepest load water line in metres and the aerial current in amperes (R.M.S. value). The values given in the second column of the table correspond to an average value of the ratio effective aerial height = 0.47 maximum aerial height This ratio varies with local conditions of the aerial and may vary between about 0.3 and 0.7. The values given in the third column of the table correspond to an average value of the ratio radiated aerial power = 0.08 total aerial power This ratio varies considerably according to the values of effective aerial height and aerial resistance. [Footnote appeared in original text.] (Clearly perceptible signals will normally be received if the R.M.S. value of the field strength at the receiver is at least 50 microvolts per metre.)
(h) (i) The main and reserve receivers shall be capable of receiving the radiotelegraph distress frequency and the class of emission assigned by the Radio Regulations for that frequency. (ii) In addition, the main receiver shall permit the reception of such of the frequencies and classes of emission used for the transmission of time signals, meteorological messages and such other communications relating to safety of navigation as may be considered necessary by the Administration. (iii) For a period not exceeding five years from the date of coming into force of the present Convention, the radiotelegraph auto alarm receiver may be used as the reserve receiver if capable of effectively producing signals in headphones or a loud-speaker with which it is connected for this purpose. When so used, it shall be connected to the reserve source of energy. (i) The main receiver shall have sufficient sensitivity to produce signals in headphones or by means of a loud-speaker when the receiver input is as low as 50 microvolts. The reserve receiver shall, except in cases where a radiotelegraph auto alarm receiver is used for this purpose, have sufficient sensitivity to produce such signals when the receiver input is as low as 100 microvolts. (j) There shall be available at all times, while the ship is at sea, a supply of electrical energy sufficient to operate the main installation over the normal range required by paragraph (g) of this Regulation as well as for the purpose of charging any batteries forming part of the radiotelegraph station. The voltage of the supply for the main installation shall, in the case of new ships, be maintained within +/-10 per cent of the rated voltage. In the case of existing ships, it shall be maintained as near the rated voltage as possible and, if practicable, within +/-10 per cent. (k) The reserve installation shall be provided with a source of energy independent of the propelling power of the ship and of the ship's electrical system. The Administration may delay the application of the requirement for a reserve source of energy for a period not exceeding three years from the date of coming into force of the present Convention, in the case of existing installations on those cargo ships of 500 tons gross tonnage and upwards but less than 1,600 tons gross tonnage which were excepted, prior to the date of the coming into force of the present Convention, from the requirement to be provided with a reserve source of energy. (l) The reserve source of energy shall preferably consist of accumulator batteries, which may be charged from the ship's electrical system, and shall under all circumstances be capable of being put into operation rapidly and of operating the reserve transmitter and receiver for at least six hours continuously under normal working conditions besides any of the additional loads mentioned in paragraphs (m) and (n) of this Regulation.[8] (m) The reserve source of energy shall be used to supply the reserve installation and the automatic alarm signal keying device specified in paragraph (r) of this Regulation if it is electrically operated. The reserve source of energy may also be used to supply: (i) the radiotelegraph auto alarm; (ii) the emergency light specified in paragraph (g) of Regulation 8 of this Chapter; (iii) the direction-finder; (iv) any device, prescribed by the Radio Regulations, to permit changeover from transmission to reception and vice versa. Subject to the provisions of paragraph (n) of this Regulation, the reserve source of energy shall not be used other than for the purposes specified in this paragraph. (n) Notwithstanding the provisions of paragraph (m) of this Regulation, the Administration may authorise the use in cargo ships of the reserve source of energy for a small number of low-power emergency circuits which are wholly confined to the upper part of the ship, such as emergency lighting on the boat deck, on condition that these can be readily disconnected if necessary, and that the source of energy is of sufficient capacity to carry the additional load or loads. (o) The reserve source of energy and its switchboard shall be as high as practicable in the ship and readily accessible to the radio officer. The switchboard shall, wherever possible, be situated in a radio room; if it is not, it shall be capable of being illuminated. (p) While the ship is at sea, accumulator batteries, whether forming part of the main installation or reserve installation, shall be brought up to the normal fully-charged condition daily. (q) All steps shall be taken to eliminate so far as is possible the causes of, and to suppress, radio interference from electrical and other apparatus on board. If necessary, steps shall be taken to ensure that the aerials attached to broadcast receivers do not cause interference to the efficient or correct working of the radiotelegraph installation. Particular attention shall be paid to this requirement in the design of new ships. (r) In addition to a means for manually transmitting the radiotelegraph alarm signal, an automatic radiotelegraph alarm signal keying device shall be provided, capable of keying the main and the reserve transmitters so as to transmit the radiotelegraph alarm signal. The device shall be capable of being taken out of operation at any time in order to permit immediate manual operation of the transmitter. If electrically operated, this keying device shall be capable of operation from the reserve source of energy. (s) At sea, the reserve transmitter, if not used for communications, shall be tested daily using a suitable artificial aerial, and at least once during each voyage using the reserve aerial if installed. The reserve source of energy shall also be tested daily. (t) All equipments forming part of the radiotelegraph installation shall be reliable, and shall be so constructed that they are readily accessible for maintenance purposes. (u) Notwithstanding the provision of Regulation 4 of this Chapter, the Administration may, in the case of cargo ships below 1,600 tons gross tonnage, relax the full requirements of Regulation 8 of this Chapter and the present Regulation, provided that the standard of the radiotelegraph station shall in no case fall below the equivalent of that prescribed under Regulation 14 and Regulation 15 of this Chapter for radiotelephone stations, so far as applicable. In particular, in the case of cargo ships of 300 tons gross tonnage and upwards but less than 500 tons gross tonnage, the Administration need not require: (i) a reserve receiver; (ii) a reserve source of energy in existing installations; (iii) protection of the main aerial against breakage by whipping; (iv) the means of communication between the radiotelegraph station and the bridge to be independent of the main communication system; (v) the range of the transmitter to be greater than 75 miles. Regulation 10 Radiotelegraph auto alarms (a) Any radiotelegraph auto alarm installed after the date of coming into force of the present Convention shall comply with the following minimum requirements: (i) In the absence of interference of any kind it shall be capable of being actuated, without manual adjustment, by any radiotelegraph alarm signal transmitted on the radiotelegraph distress frequency by any coast station, ship's emergency or survival craft transmitter operating in accordance with the Radio Regulations, provided that the strength of the signal at the receiver input is greater than 100 microvolts and less than 1 volt. (ii) In the absence of interference of any kind, it shall be actuated by either three or four consecutive dashes when the dashes vary in length from 3.5 to as near 6 seconds as possible and the spaces vary in length between 1.5 seconds and the lowest practicable value, preferably not greater than 10 milliseconds. (iii) It shall not be actuated by atmospherics or by any signal other than the radiotelegraph alarm signal, provided that the received signals do not in fact constitute a signal falling within the tolerance limits indicated in (ii). (iv) The selectivity of the radiotelegraph auto alarm shall be such as to provide a practically uniform sensitivity over a band extending not less than 4 kc/s and not more than 8 kc/s on each side of the radiotelegraph distress frequency and to provide outside this band a sensitivity which decreases as rapidly as possible in conformity with the best engineering practice. (v) If practicable, the radiotelegraph auto alarm shall, in the presence of atmospherics or interfering signals, automatically adjust itself so that within a reasonably short time it approaches the condition in which it can most readily distinguish the radiotelegraph alarm signal. (vi) When actuated by a radiotelegraph alarm signal, or in the event of failure of the apparatus, the radiotelegraph auto alarm shall cause a continuous audible warning to be given in the radiotelegraph operating room, in the radio officer's sleeping accommodation and on the bridge. If practicable, warning shall also be given in the case of failure of any part of the whole alarm receiving system. Only one switch for stopping the warning shall be provided and this shall be situated in the radiotelegraph operating room. (vii) For the purpose of regularly testing the radiotelegraph auto alarm, the apparatus shall include a generator pre-tuned to the radiotelegraph distress frequency and a keying device by means of which a radiotelegraph alarm signal of the minimum strength indicated in (i) is produced. A means shall also be provided for attaching headphones for the purpose of listening to signals received on the radiotelegraph auto alarm. (viii) The radiotelegraph auto alarm shall be capable of withstanding vibration, humidity and changes of temperature, equivalent to severe conditions experienced on board ships at sea, and shall continue to operate under such conditions. (b) Before a new type of radiotelegraph auto alarm is approved, the Administration concerned shall be satisfied, by practical tests made under operating conditions equivalent to those obtaining in practice, that the apparatus complies with paragraph (a) of this Regulation. (c) In ships fitted with a radiotelegraph auto alarm, its efficiency shall be tested by a radio officer at least once every 24 hours while at sea. If it is not in working order, the radio officer shall report that fact to the master or officer on watch on the bridge. (d) A radio officer shall periodically check the proper functioning of the radiotelegraph auto alarm receiver, with its normal aerial connected, by listening to signals and by comparing them with similar signals received on the radiotelegraph distress frequency on the main installation. (e) As far as practicable, the radiotelegraph auto alarm, when connected to an aerial, shall not affect the accuracy of the direction-finder.

CHAPTER V SAFETY OF NAVIGATION Regulation 1 Application This Chapter, unless otherwise expressly provided in this Chapter, applies to all ships on all voyages, except ships of war and ships solely navigating the Great Lakes of North America and their connecting and tributary waters as far east as the lower exit of the St. Lambert Lock at Montreal in the Province of Quebec, Canada. Regulation 2 Danger messages (a) The master of every ship which meets with dangerous ice, a dangerous derelict, or any other direct danger to navigation, or a tropical storm, or encounters sub-freezing air temperatures associated with gale force winds causing severe ice accretion on superstructures, or winds of force 10 or above on the Beaufort scale for which no storm warning has been received, is bound to communicate the information by all the means at his disposal to ships in the vicinity, and also to the competent authorities at the first point on the coast with which he can communicate. The form in which the information is sent is not obligatory. It may be transmitted either in plain language (preferably English) or by means of the International Code of Signals. It should be broadcast to all ships in the vicinity and sent to the first point on the coast to which communication can be made, with a request that it be transmitted to the appropriate authorities. (b) Each Contracting Government will take all steps necessary to ensure that when intelligence of any of the dangers specified in paragraph (a) is received, it will be promptly brought to the knowledge of those concerned and communicated to other interested Governments. (c) The transmission of messages respecting the dangers specified is free of cost to the ships concerned. (d) All radio messages issued under paragraph (a) of this Regulation shall be preceded by the Safety Signal, using the procedure as prescribed by the Radio Regulations as defined in Regulation 2 of Chapter IV. Regulation 3 Information required in danger messages The following information is required in danger messages: (a) Ice, derelicts and other direct dangers to navigation. (i) The kind of ice, derelict or danger observed; (ii) the position of the ice, derelict or danger when last observed; (iii) the time and date (Greenwich Mean Time) when danger last observed. (b) Tropical storms (hurricanes in the West Indies, typhoons in the China Sea, cyclones in Indian waters, and storms of a similar nature in other regions). (i) A statement that a tropical storm has been encountered. This obligation should be interpreted in a broad spirit, and information transmitted whenever the master has good reason to believe that a tropical storm is developing or exists in his neighbourhood. (ii) Time, date (Greenwich Mean Time) and position of ship when the observation was taken. (iii) As much of the following information as is practicable should be included in the message: - barometric pressure, preferably corrected (stating millibars, inches, or millimetres, and whether corrected or uncorrected); - barometric tendency (the change in barometric pressure during the past three hours); - true wind direction; - wind force (Beaufort scale); - state of the sea (smooth, moderate, rough, high); - swell (slight, moderate, heavy) and the true direction from which it comes. Period or length of swell (short, average, long) would also be of value; - true course and speed of ship. (c) Subsequent observations. When a master has reported a tropical or other dangerous storm, it is desirable, but not obligatory, that further observations be made and transmitted hourly, if practicable, but in any case at intervals of not more than three hours, so long as the ship remains under the influence of the storm. (d) Winds of force 10 or above on the Beaufort scale for which no storm warning has been received. This is intended to deal with storms other than the tropical storms referred to in paragraph (b); when such a storm is encountered, the message should contain similar information to that listed under paragraph (b) but excluding the details concerning sea and swell. (e) Sub-freezing air temperatures associated with gale force winds causing severe ice accretion on superstructures. (i) Time and date (Greenwich Mean Time). (ii) Air temperature.

Regulation 4 Meteorological services (a) The Contracting Governments undertake to encourage the collection of meteorological data by ships at sea and to arrange for their examination, dissemination and exchange in the manner most suitable for the purpose of aiding navigation. Administrations shall encourage the use of instruments of a high degree of accuracy, and shall facilitate the checking of such instruments upon request. (b) In particular, the Contracting Governments undertake to cooperate in carrying out, as far as practicable, the following meteorological arrangements: (i) To warn ships of gales, storms and tropical storms, both by the issue of radio messages and by the display of appropriate signals at coastal points. (ii) To issue daily, by radio, weather bulletins suitable for shipping, containing data of existing weather, waves and ice, forecasts and, when practicable, sufficient additional information to enable simple weather charts to be prepared at sea and also to encourage the transmission of suitable facsimile weather charts. (iii) To prepare and issue such publications as may be necessary for the efficient conduct of meteorological work at sea and to arrange, if practicable, for the publication and making available of daily weather charts for the information of departing ships. (iv) To arrange for selected ships to be equipped with tested instruments (such as a barometer, a barograph, a psychrometer, and suitable apparatus for measuring sea temperature) for use in this service, and to take meteorological observations at main standard times for surface synoptic observations (at least four times daily, whenever circumstances permit) and to encourage other ships to take observations in a modified form, particularly when in areas where shipping is sparse; these ships to transmit their observations by radio for the benefit of the various official meteorological services, repeating the information for the benefit of ships in the vicinity. When in the vicinity of a tropical storm, or of a suspected tropical storm, ships should be encouraged to take and transmit their observations at more frequent intervals whenever practicable, bearing in mind navigational preoccupations of ships' officers during storm conditions. (v) To arrange for the reception and transmission by coast radio stations of weather messages from and to ships. Ships which are unable to communicate direct with shore shall be encouraged to relay their weather messages through ocean weather ships or through other ships which are in contact with shore. (vi) To encourage all masters to inform ships in the vicinity and also shore stations whenever they experience a wind speed of 50 knots or more (force 10 on the Beaufort scale). (vii) To endeavour to obtain a uniform procedure in regard to the international meteorological services already specified, and, as far as is practicable, to conform to the Technical Regulations and recommendations made by the World Meteorological Organization, to which the Contracting Governments may refer for study and advice any meteorological question which may arise in carrying out the present Convention. (c) The information provided for in this Regulation shall be furnished in form for transmission and transmitted in the order of priority prescribed by the Radio Regulations, and during transmission "to all stations" of meteorological information, forecasts and warnings, all ship stations must conform to the provisions of the Radio Regulations. (d) Forecasts, warnings, synoptic and other meteorological reports intended for ships shall be issued and disseminated by the national service in the best position to serve various zones and areas, in accordance with mutual arrangements made by the Contracting Governments concerned. Regulation 5 Ice patrol service (a) The Contracting Governments undertake to continue an ice patrol and a service for study and observation of ice conditions in the North Atlantic. During the whole of the ice season the south-eastern, southern and south-western limits of the regions of icebergs in the vicinity of the Grand Banks of Newfoundland shall be guarded for the purpose of informing passing ships of the extent of this dangerous region; for the study of ice conditions in general; and for the purpose of affording assistance to ships and crews requiring aid within the limits of operation of the patrol ships. During the rest of the year the study and observation of ice conditions shall be maintained as advisable. (b) Ships and aircraft used for the ice patrol service and the study and observation of ice conditions may be assigned other duties by the managing Government, provided that such other duties do not interfere with their primary purpose or increase the cost of this service. Regulation 6 Ice patrol. Management and cost (a) The Government of the United States of America agrees to continue the management of the ice patrol service and the study and observation of ice conditions, including the dissemination of information received therefrom. The Contracting Governments specially interested in these services undertake to contribute to the expense of maintaining and operating these services; each contribution to be based upon the total gross tonnage of the vessels of each contributing Government passing through the regions of icebergs guarded by the Ice Patrol; in particular, each Contracting Government specially interested undertakes to contribute annually to the expense of maintaining and operating these services a sum determined by the ratio which the total gross tonnage of that Contracting Government's vessels passing during the ice season through the regions of icebergs guarded by the Ice Patrol bears to the combined total gross tonnage of the vessels of all contributing Governments passing during the ice season through the regions of icebergs guarded by the Ice Patrol. Non-contracting Governments specially interested may contribute to the expense of maintaining and operating these services on the same basis. The managing Government will furnish annually to each contributing Government a statement of the total cost of maintaining and operating the Ice Patrol and of the proportionate share of each contributing Government. (b) Each of the contributing Governments has the right to alter or discontinue its contribution, and other interested Governments may undertake to contribute to the expense. The contributing Government which avails itself of this right will continue responsible for its current contribution up to the 1 September following the date of giving notice of intention to alter or discontinue its contribution. To take advantage of the said right it must give notice to the managing Government at least six months before the said 1 September. (c) If, at any time, the United States Government should desire to discontinue these services, or if one of the contributing Governments should express a wish to relinquish responsibility for its pecuniary contribution, or to have its contribution altered, or another Contracting Government should desire to undertake to contribute to the expense, the contributing Governments shall settle the question in accordance with their mutual interests. (d) The contributing Governments shall have the right by common consent to make from time to time such alterations in the provisions of this Regulation and of Regulation 5 of this Chapter as appear desirable. (e) Where this Regulation provides that a measure may be taken after agreement among the contributing Governments, proposals made by any Contracting Government for effecting such a measure shall be communicated to the managing Government which shall approach the other contributing Governments with a view to ascertaining whether they accept such proposals, and the results of the enquiries thus made shall be sent to the other contributing Governments and the Contracting Government making the proposals. In particular, the arrangements relating to contributions to the cost of the services shall be reviewed by the contributing Governments at intervals not exceeding three years. The managing Government shall initiate the action necessary to this end. Regulation 7 Speed near ice When ice is reported on or near his course the master of every ship at night is bound to proceed at a moderate speed or to alter his course so as to go well clear of the danger zone. Regulation 8 North Atlantic routes (a) The practice of following recognised routes across the North Atlantic in both directions and, in particular, routes in converging areas of both sides of the North Atlantic, has contributed to the avoidance of collisions between ships and with icebergs, and should be recommended to all ships concerned. (b) The selection of the routes and the initiation of action with regard to them, and the delineation of what constitutes converging areas, is left to the responsibility of the shipping companies concerned. The Contracting Governments will assist the companies, when requested to do so, by placing at their disposal any information bearing on the routes which may be in the possession of the Governments. (c) The Contracting Governments undertake to impose on the companies the obligations to give public notice of the regular routes which they propose their ships should follow, and of any changes made in these routes. They will also use their influence to induce the owners of all passenger ships crossing the Atlantic to follow the recognised routes, and will do everything in their power to ensure adherence to such routes in the converging areas by all ships, so far as circumstances will permit. They will also induce the owners of all ships crossing the Atlantic bound to or from ports of the United States or Canada via the vicinity of the Grand Banks of Newfoundland to avoid, as far as practicable, the fishing banks of Newfoundland north of latitude 43deg.N. during the fishing season, and to pass outside regions known or believed to be endangered by ice. (d) The Government managing the ice patrol service is requested to report to the Administration concerned any passenger ship which is observed not to be on any regular, recognised or advertised route and any ship which crosses the above mentioned fishing banks during the fishing season, or which when proceeding to or from ports of the United States or Canada passes through regions known or believed to be endangered by ice. Regulation 9 Misuse of distress signals The use of an international distress signal, except for the purpose of indicating that a ship or aircraft is in distress, and the use of any signal which may be confused with an international distress signal, are prohibited on every ship or aircraft. Regulation 10 Distress messages - obligations and procedures (a) The master of a ship at sea, on receiving a signal from any source that a ship or aircraft or survival craft thereof is in distress, is bound to proceed with all speed to the assistance of the persons in distress informing them if possible that he is doing so. If he is unable or, in the special circumstances of the case, considers it unreasonable or unnecessary to proceed to their assistance, he must enter in the logbook the reason for failing to proceed to the assistance of the persons in distress. (b) The master of a ship in distress, after consultation, so far as may be possible, with the masters of the ships which answer his call for assistance, has the right to requisition such one or more of those ships as he considers best able to render assistance, and it shall be the duty of the master or masters of the ship or ships requisitioned to comply with the requisition by continuing to proceed with all speed to the assistance of persons in distress. (c) The master of a ship shall be released from the obligation imposed by paragraph (a) of this Regulation when he learns that one or more ships other than his own have been requisitioned and are complying with the requisition. (d) The master of a ship shall be released from the obligation imposed by paragraph (a) of this Regulation, and, if his ship has been requisitioned, from the obligation imposed by paragraph (b) of this Regulation, if he is informed by the persons in distress or by the master of another ship which has reached such persons that assistance is no longer necessary. (e) The provisions of this Regulation do not prejudice the International Convention for the unification of certain rules with regard to Assistance and Salvage at Sea, signed at Brussels on 23 September 1910, particularly the obligation to render assistance imposed by Article 11 of that Convention. Regulation 11 Signalling lamps All ships of over 150 tons gross tonnage, when engaged on international voyages, shall have on board an efficient daylight signalling lamp which shall not be solely dependent upon the ship's main source of electrical power. Regulation 12 Radio direction-finding apparatus (a) All ships of 1,600 tons gross tonnage and upwards, when engaged on international voyages, shall be fitted with radio direction-finding apparatus complying with the provisions of Regulation 11 of Chapter IV. (b) The Administration may, in areas where it considers it unreasonable or unnecessary for such apparatus to be carried, exempt any ship under 5,000 tons gross tonnage from this requirement, due regard being had to the fact that radio direction-finding apparatus is of value both as a navigational instrument and as an aid to locating ships, aircraft or survival craft. Regulation 13 Manning The Contracting Governments undertake, each for its national ships, to maintain, or, if it is necessary, to adopt, measures for the purpose of ensuring that, from the point of view of safety of life at sea, all ships shall be sufficiently and efficiently manned. Regulation 14 Aids to navigation The Contracting Governments undertake to arrange for the establishment and maintenance of such aids to navigation, including radio beacons and electronic aids as, in their opinion, the volume of traffic justifies and the degree of risk requires, and to arrange for information relating to these aids to be made available to all concerned. Regulation 15 Search and rescue (a) Each Contracting Government undertakes to ensure that any necessary arrangements are made for coast watching and for the rescue of persons in distress at sea round its coasts. These arrangements should include the establishment, operation and maintenance of such maritime safety facilities as are deemed practicable and necessary having regard to the density of the seagoing traffic and the navigational dangers and should, so far as possible, afford adequate means of locating and rescuing such persons. (b) Each Contracting Government undertakes to make available information concerning its existing rescue facilities and the plans for changes therein, if any. Regulation 16 Life-saving signals The following signals shall be used by life-saving stations and maritime rescue units when communicating with ships or persons in distress and by ships or persons in distress when communicating with life-saving stations and maritime rescue units. The signals used by aircraft engaged in search and rescue operations to direct ships are indicated in paragraph (d) below. An illustrated table describing the signals listed below shall be readily available to the officer of the watch of every ship to which this Chapter applies. (a) Replies from life-saving stations or maritime rescue units to distress signals made by a ship or person:
If necessary the day signals may be given at night or the night signals by day. (b) Landing signals for the guidance of small boats with crews or persons in distress:
(c) Signals to be employed in connection with the use of shore life-saving apparatus:
(d) Signals used by aircraft engaged on search and rescue operations to direct ships towards an aircraft, ship or person in distress (see explanatory Note below):
(i) The following procedures performed in sequence by an aircraft mean that the aircraft is directing a surface craft towards an aircraft or a surface craft in distress: (1) circling the surface craft at least once; (2) crossing the projected course of the surface craft close ahead at a low altitude, opening and closing the throttle or changing the propeller pitch; (3) heading in the direction in which the surface craft is to be directed. Repetition of such procedures has the same meaning. (ii) The following procedure performed by an aircraft means that the assistance of the surface craft to which the signal is directed is no longer required: - crossing the wake of the surface craft close astern at a low altitude, opening and closing the throttle or changing the propeller pitch. Note: Advance notification of changes in these signals will be given by the Organization as necessary. Regulation 17 Pilot ladders Ships engaged on voyages in the course of which pilots are likely to be employed shall comply with the following requirements respecting pilot ladders: (a) The ladder shall be kept in good order and for use only by officials and other persons while a ship is arriving at or leaving a port, and for embarkation and disembarkation of pilots.

CHAPTER VI CARRIAGE OF GRAIN Regulation 1 Application Unless expressly provided otherwise, this Chapter applies to the carriage of grain in all ships to which the present Regulations apply. Regulation 2 Definition The term "grain" includes wheat, maize (corn), oats, rye, barley, rice, pulses and seeds. Regulation 3 Trimming Where grain is loaded in a ship, all necessary and reasonable precautions shall be taken to prevent the grain from shifting. If any hold or compartment is entirely filled with bulk grain, the grain shall be trimmed so as to fill all the spaces between the beams and in the wings and ends. Regulation 4 Stowage of full holds and compartments Subject to the provisions of Regulation 6 of this Chapter, if any hold or compartment is entirely filled with bulk grain it shall be divided either by a longitudinal bulkhead or shifting boards in line with, or not more than 5 per cent of the moulded breadth of the ship from, the centre line or by longitudinal bulkheads or shifting boards off the centre line of the ship provided that the distance between them shall not exceed 60 per cent of the moulded breadth of the ship and that in the latter case trimming hatches of suitable size shall be provided in the wings at longitudinal intervals of not more than 25 feet (or 7.62 metres) with end trimming hatches placed not more than 12 feet (or 3.66 metres) from transverse bulkheads. In every case the longitudinal bulkheads or shifting boards shall be properly constructed and fitted grain-tight with proper fillings between the beams. In holds such longitudinal bulkheads or shifting boards shall extend downwards from the underside of the deck to a distance of at least one-third of the depth of the hold or 8 feet (or 2.44 metres) whichever is the greater. In compartments in 'tween decks and superstructures they shall extend from deck to deck. In all cases the longitudinal bulkheads or shifting boards shall extend to the top of the feeders of the hold or compartment in which they are situated. Provided that in the case of ships loaded with bulk grain other than linseed in which a metacentric height (after correction for the free surface effects of liquids in tanks) is maintained throughout the voyage of not less than 12 inches (or 0.31 metres) in the case of one or two deck ships and not less than 14 inches (or 0.36 metres) in the case of other ships, longitudinal bulkheads or shifting boards need not be fitted: (a) below and within 7 feet (or 2.13 metres) of a feeder, but only in way of a hatchway, if that feeder contains, or all the feeders collectively feeding a compartment contain, not less than 5 per cent of the quantity of grain carried in the compartment which is fed; (b) in feeders which meet the requirements of paragraph (a) of this Regulation and which have such dimensions that the free grain surface will remain within the feeders throughout the voyage after allowing for a sinkage of grain amounting to 2 per cent of the volume of the compartment fed and a shift of the free grain surface to an angle of 12 degrees to the horizontal; in this case the possible effects of the above mentioned movement of the free grain surfaces within the feeders shall be taken into account in calculating the metacentric height given above; (c) in way of the hatchway where the bulk grain beneath the hatchway is trimmed in the form of a saucer hard up to the deckhead beyond the hatchway and is topped off with bagged grain or other suitable bagged cargo extending to a height in the centre of the saucer of not less than 6 feet (or 1.83 metres) above the top of the bulk grain (measured below the deck line); the bagged grain or other suitable bagged cargo shall fill the hatchway and the saucer below and shall be stowed tightly against the deckhead, the longitudinal bulkheads, the hatchway beams and the hatchway side and end coamings. Regulation 5 Stowage of partly filled holds and compartments Subject to the provisions of Regulation 6 of this Chapter, if any hold or compartment is partly filled with bulk grain: (a) it shall be divided by a longitudinal bulkhead or shifting boards, in line with, or not more than 5 per cent of the moulded breadth of the ship from, the centre line or by longitudinal bulkheads or shifting boards off the centre line of the ship provided that the distance between them shall not exceed 60 per cent of the moulded breadth of the ship. In every case the longitudinal bulkheads or shifting boards shall be properly constructed and shall extend from the bottom of the hold or deck, as the case may be, to a height of not less than 2 feet (or 0.61 metres) above the surface of the bulk grain. Provided that, except in the case of holds partly filled with linseed in bulk, longitudinal bulkheads or shifting boards need not be fitted in way of the hatchway in the case of ships in which a metacentric height (after correction for the free surface effects of liquids in tanks) is maintained throughout the voyage of not less than 12 inches (or 0.31 metres) in the case of one or two deck ships and not less than 14 inches (or 0.36 metres) in the case of other ships; (b) the bulk grain shall be levelled and topped off with bagged grain or other suitable cargo tightly stowed and extending to a height of not less than 4 feet (or 1.22 metres) above the top of the bulk grain within spaces divided by such a longitudinal bulkhead or shifting boards, and not less than 5 feet (or 1.52 metres) within spaces not so divided. The bagged grain or other suitable cargo shall be supported on suitable platforms laid over the whole surface of the bulk grain; such platforms shall consist of bearers spaced not more than 4 feet (or 1.22 metres) apart and 1 inch (or 25 millimetres) boards laid thereon spaced not more than 4 inches (or 0.10 metres) apart or of strong separation cloths with adequate overlapping. Regulation 6 Exceptions to the requirements for longitudinal bulkheads The fitting of longitudinal bulkheads or shifting boards in accordance with the provisions of Regulations 4 and 5 of this Chapter shall not be required: (a) in a lower hold (which term also includes the lower part of the hold of a single-deck ship) if the bulk grain therein does not exceed one-third of the capacity of the hold, or where such lower hold is divided by a shaft tunnel, one-half the capacity of that lower hold; (b) in any space in a 'tween deck or superstructure provided that the wings are tightly stowed with bagged grain or other suitable cargo to a breadth on each side of not less than 20 per cent of the breadth of the ship in way thereof; and (c) in those parts of spaces where the maximum breadth of the deckhead within the said spaces does not exceed one-half of the moulded breadth of the ship. Regulation 7 Feeders (a) (i) Any hold or compartment which is entirely filled with bulk grain shall be fed by suitably placed and properly constructed feeders, except as otherwise provided in paragraph (c) of Regulation 4 and Regulations 8 and 12 of this Chapter so as to secure a free flow of grain from the feeder to all parts of that hold or compartment. (ii) Each feeder shall contain not less than 2 per cent of the quantity of grain carried in that part of the hold or compartment that it feeds except as otherwise provided for in paragraph (a) of Regulation 4 of this Chapter. (b) When bulk grain is carried in deep tanks primarily constructed for the carriage of liquids to which paragraph (c) of Regulation 6 of this Chapter applies or that are divided by one or more permanent steel longitudinal divisions fitted grain-tight, feeders to the tanks may be omitted if the tanks and tank hatchways are completely filled and the hatch covers secured. Regulation 8 Common loading For the purpose of Regulations 4 and 7 of this Chapter lower holds and 'tween deck spaces over them may be loaded as one compartment under the following conditions: (a) longitudinal bulkheads or shifting boards shall be fitted deck to deck in the 'tween deck of a ship having two decks; in all other cases the longitudinal bulkheads or shifting boards shall be fitted for the upper third of the total depth of the common spaces; (b) in order to secure an adequate flow of grain all spaces shall comply with the requirements of Regulation 9 of this Chapter and openings shall be provided in the wings of the deck immediately below the uppermost deck forward and aft of the ends of the hatchways as necessary to provide in combination with the hatchways a maximum feeding distance of 8 feet (or 2.44 metres) measured in a fore and aft line. Regulation 9 Trimming and bagging of end spaces When the distance, measured in a fore and aft line, from any part of a hold or compartment to the nearest feeder exceeds 25 feet (or 7.62 metres) the bulk grain in the end spaces beyond 25 feet (or 7.62 metres) from the nearest feeder shall be levelled off at a depth of at least 6 feet (or 1.83 metres) below the deck, and the end spaces filled with bagged grain built up on a suitable platform as required in paragraph (b) of Regulation 5 of this Chapter. Regulation 10 Bulk grain in 'tween decks and superstructures Bulk grain shall not be carried above deck, in the 'tween deck of a two deck ship, or in the uppermost 'tween deck of a ship having more than two decks except under the following conditions: (a) the bulk grain or other cargo shall be stowed so as to ensure maximum stability: in all cases either a metacentric height (after correction for the free surface effects of liquids in tanks) shall be maintained throughout the voyage of not less than 12 inches (or 0.31 metres) in the case of one or two deck ships and 14 inches (or 0.36 metres) in the case of other ships or, alternatively, the aggregate quantity of bulk grain or other cargo carried above deck, in the 'tween deck spaces of a two deck ship or in the uppermost 'tween deck spaces of a ship having more than two decks shall not exceed 28 per cent by weight of the total cargo below the 'tween deck where the master is satisfied that the ship will have adequate stability throughout the voyage; the limitation of 28 per cent specified above shall not apply when the grain carried above deck or in the uppermost 'tween deck spaces is oats, barley or cotton seed; (b) the deck area of any portion of the spaces referred to in this Regulation which contains bulk grain and which is only partly filled shall not exceed 1,000 square feet (or 93 square metres); and (c) all spaces referred to in this Regulation in which bulk grain is stowed shall be subdivided by transverse bulkheads at intervals of not more than 100 feet (or 30.50 metres); when this distance is exceeded the excess space shall be entirely filled with bagged grain or other suitable cargo. Regulation 11 Limitation on number of partly filled holds and compartments Except in the case of ships in which a metacentric height (after correction for the free surface effects of liquids in tanks) is maintained throughout the voyage of not less than 12 inches (or 0.31 metres) in the case of one or two deck ships and not less than 14 inches (or 0.36 metres) in the case of other ships, not more than two holds or compartments shall be partly filled with bulk grain, except that other holds or compartments may be partly filled with bulk grain if they are filled up to the deckhead with bagged or other suitable cargo. For the purpose of this Regulation: (a) superimposed 'tween decks shall be regarded as separate compartments and separate from any lower hold below them; (b) feeders and the partly filled spaces referred to in paragraph (b) of Regulation 10 of this Chapter shall not be regarded as compartments; and (c) holds or compartments provided with one or more grain-tight longitudinal divisions shall be regarded as one hold or compartment. Regulation 12 Stowage of specially suitable ships (a) Notwithstanding anything contained in Regulations 4 to 11 of this Chapter, bulk grain may be carried without regard to the requirements specified therein in ships which are constructed with two or more vertical or sloping grain-tight longitudinal divisions suitably disposed to limit the effect of any transverse shift of grain under the following conditions: (i) as many holds and compartments as possible shall be full and trimmed full; (ii) for any specified arrangement of stowage the ship will not list to an angle greater than 5 degrees at any stage of the voyage where: (1) in holds or compartments which have been trimmed full the grain surface settles 2 per cent by volume from the original surface and shifts to an angle of 12 degrees with that surface under all boundaries of these holds and compartments which have an inclination of less than 30 degrees to the horizontal; and (2) in partly filled holds or compartments free grain surfaces settle and shift as in sub-paragraph (ii)(1) of this paragraph or to such larger angle as may be deemed necessary by the Administration, or by a Contracting Government on behalf of the Administration, and grain surfaces if overstowed in accordance with Regulation 5 of this Chapter shift to an angle of 8 degrees with the original levelled surfaces. For the purposes of sub-paragraph (ii) of this paragraph shifting boards if fitted will be considered to limit the transverse shift of the surface of the grain; (iii) the master is provided with a grain loading plan covering the stowage arrangements to be adopted and a stability booklet, both approved by the Administration, or by a Contracting Government on behalf of the Administration, showing the stability conditions upon which the calculations given in sub-paragraph (ii) of this paragraph are based. (b) The Administration, or a Contracting Government on behalf of the Administration, shall prescribe the precautions to be taken against shifting in all other conditions of loading of ships designed in accordance with paragraph (a) of this Regulation which meet the requirements of sub-paragraphs (ii) and (iii) of that paragraph. (c) The Administration, or a Contracting Government on behalf of the Administration, shall prescribe the precautions to be taken against shifting in a ship of any other design which meets the requirements of sub-paragraphs (ii) and (iii) of paragraph (a) of this Regulation. Regulation 13 Water ballast tanks Double bottom tanks which are used to meet a stability requirement in ships loading bulk grain shall have adequate watertight longitudinal subdivision except where the width of the tank measured at half length does not exceed 60 per cent of the ship's moulded breadth. Regulation 14 Bagged grain Bagged grain shall be carried in sound bags which shall be well filled and securely closed. Regulation 15 Grain loading plans (a) A grain loading plan approved for a ship whether by the Administration or by a Contracting Government on behalf of the Administration shall be accepted by other Contracting Governments as evidence that the ship when loaded in accordance with such plans meets the requirements of this Chapter or equivalent arrangements which have been accepted under Regulation 5 of Chapter I. (b) Such plan shall be approved after taking into account the requirements of this Chapter, the various circumstances of loading on departure and arrival, and the stability of the ship. It shall indicate the main characteristics of the fittings used to prevent the shifting of cargo. (c) Such plan shall be annotated in one or more languages of which one shall be one of the Convention languages. (d) A copy of such plan shall be supplied to the master of the ship, who if so required shall produce it for the inspection of the appropriate authority of the port in which loading takes place. (e) Pending the adoption of international regulations concerning the strength of grain fittings and the provision of feeding holes in hatch coamings, a ship loading grain which does not produce a grain loading plan approved by the Administration, or by a Contracting Government on behalf of the Administration, shall load in accordance with detailed rules issued to supplement the provisions of this Chapter by the Contracting Government of the country in which the loading port is situated. Regulation 16 Exemptions for certain voyages The Administration, or a Contracting Government on behalf of the Administration, may, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of any of the requirements of Regulations 3 to 15 of this Chapter unreasonable or unnecessary, exempt from those particular requirements individual ships or classes of ships.

Instrument of acceptance deposited for Australia 20 December 1967. [4] The Convention entered into force generally 26 May 1965. [5] The Convention entered into force for Australia 20 March 1968. [6] Such ships are subject to special requirements relative to safety purposes, the present requirements being contained in the United States-Canada agreement of 1952, entitled "Promotion of Safety on the Great Lakes by Means of Radio". [Footnote appeared in original text.] [7] In the absence of a direct measurement of the field strength the following data may be used as a guide for approximately determining the normal range: Normal range in milesMetre-amperes[8] For the purpose of determining the electrical load to be supplied by the reserve source of energy, the following formula is recommended as a guide: 1/2 of the transmitter current comsumption with the key down (mark) + 1/2 of the transmitter current consumption with the key up (space) + current consumption of receiver and additional circuits connected to the reserve source of energy. [Footnote appeared in original text.] [9] In the absence of a measurement of the field strength, it may be assumed that this range will be obtained if the product of the height of the aerial above the water line and the aerial current (R.M.S. value) is 10 metre-amperes. [Footnote appeared in original text.] [10] It may be assumed that the purposes of this Regulation will be satisfied by the following performance. At least 10 watts input to the anode of the final stage of a radiofrequency output of at least 2.0 watts (A2 emission) at 500 kc/s into an artificial aerial having an effective resistance of 15 ohms and 100 X 10-12 farads capacitance in series. The depth of modulation shall be at least 70 per cent. [Footnote appeared in original text.] [11] In the absence of field strength measurements, it may be assumed that this range will be obtained by a power in the aerial of 15 watts (unmodulated carrier) with an aerial efficiency of 27 per cent. [Footnote appeared in original text.] [12] For the purpose of determining the electrical load to be supplied by batteries required to have six hours reserve capacity, the following formula is recommended as a guide: 1/2 of the current consumption necessary for speech transmission + current consumption of receiver + current consumption of all additional loads to which the batteries may supply energy in time of distress or emergency.
