1 Unless expressly provided otherwise, this chapter shall apply to ships the keels of which are laid or which are at a similar stage of construction on or after 1 July 1986.
2 For the purpose of this chapter the term "a similar stage of construction" means the stages at which:
.1 construction identifiable with a specific ship begins; and
.2 assembly of that ship has commenced comprising at least 50 tonnes or 1 % of the estimated mass of all structural material, whichever is less.
3 For the purpose of this chapter:
.1 the expression "ships constructed" means "ships the keels of which are laid or which are at a similar stage of construction ";
.2 the expression "all ships" means "ships constructed before, on or after 1 July 1986"; the expressions "all passenger ships" and "all cargo ships" shall be construed accordingly;
.3 a cargo ship, whenever built, which is converted to a passenger ships shall be treated as a passenger ship constructed on the date on which such a conversion commences.
4 For ships constructed before 1 July 1986, the Administration shall:
.1 ensure that, subject to the provisions of paragraphs 4.2 and 4.3, the requirements which are applicable under chapter III of the International Convention for the Safety of Life at Sea, 1974, in force prior to 1 July 1986 to new or existing ships as prescribed by that chapter are complied with;
.2 consider the life-saving appliances and arrangements in ships which do not comply with the requirements referred to in paragraph 4.1, with a view to securing, so far as this is reasonable and practicable and as early as possible, substantial compliance with those requirements;
.3 ensure that when life-saving appliances or arrangements on such ships are replaced or such ships undergo repairs, alterations or modifications of a major character which involve replacement of, or any addition to, their existing life-saving appliances or arrangements, such life-saving appliances or arrangements, in so far as is reasonable and practicable, comply with the requirements of this chapter. However, if a survival craft is replaced without replacing its launching appliance, or vice versa, the survival craft or launching appliance may be of the same type as that replaced;
.4 approve the life-saving appliances to be provided in compliance with paragraph 6. The Administration may permit those life-saving appliances provided on board ships prior to 1 July 1991 not to comply fully with the requirements of this chapter as long as they remain in a satisfactory condition;
.5 except as provided for survival craft and launching appliances referred to in paragraph 4.3, ensure that life-saving appliances replaced or installed on or after 1 July 1991 are evaluated, tested and approved in accordance with the requirements of regulations 4 and 5.
5 With respect to ships constructed before 1 July 1986, the requirements of regulations III/8, 9, 10, 18, 21.3, 21.4, 25, 26.3, 27.2, 27.3 and 30.2.7 and, to the extent prescribed therein, regulation 19 shall apply.
6 With respect to ships constructed before 1 February 1992, regulation III/6.2, shall apply not later than 1 February 1995.
1 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 which, in the course of their voyage, do not proceed more than 20 miles from the nearest land.
2 In the case of passenger ships which are employed in special trades for the carriage of large numbers of special trade passengers such 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, provided that such ships comply fully with the provision of:
.1 the rules annexed to the Special Trade Passenger Ships Agreement, 1971; and
.2 the rules annexed to the Protocol on Space Requirements for Special Trade Passenger Ships, 1973.
For the purpose of this chapter, unless expressly provided otherwise:
1 Certificated person is a person who holds a certificate of proficiency in survival craft issued under the authority of, or recognized as valid by, the Administration in accordance with the requirements of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, in force; or a person who holds a certificate issued or recognized by the Administration of a State not a Party to that Convention for the same purpose as the convention certificate.
2 Detection is the determination of the location of survivors or survival craft.
3 Embarkation ladder is the ladder provided at survival craft embarkation stations to permit safe access to survival craft after launching.
4 Float-free launching is that method of launching a survival craft whereby the craft is automatically released from a sinking ship and is ready for use.
5 Free-fall launching is that method of launching a survival craft whereby the craft with its complement of persons and equipment on board is released and allowed to fail into the sea without any restraining apparatus.
6 Immersion suit is a protective suit which reduces the body heat-loss of a person wearing it in cold water.
7 Inflatable appliance is an appliance which depends upon non-rigid, gas filled chambers for buoyance and which is normally kept uninflated until ready for use.
8 Inflated appliance is an appliance which depends upon non-rigid, gas filled chambers for buoyancy and which is kept inflated and ready for use at all times.
9 Launching appliances or arrangements is a means of transferring a survival craft or rescue boat from its stowed position safely to the water.
10 Length is 96% of the total length on a waterline at 85% of the least moulded depth measured from the top of the keel, or the length from the fore-side of the stem to the axis of the rudder stock on that waterline, if that be greater. In ships designed with a rake of keel the waterline on which this is measured shall be parallel to the designed waterline.
11 Moulded depth
.1 The moulded depth is the vertical distance measured from the top of the keel to the top of the freeboard deck beam at side. In wood and composite ships the distance is measured from the lower edge of the keel rabbet. Where the form at the lower part of the midship section is of a hollow character, or where thick garboards are fitted, the distance is measured from the point where the line of the flat of the bottom continued inwards cuts the side of the keel.
.2 In ships having rounded gunwales, the moulded depth shall be measured to the point of intersection of the moulded lines of the deck and side shell plating, the lines extending as though the gunwales were of angular design.
.3 Where the freeboard deck is stepped and the raised part of the deck extends over the point at which the moulded depth is to be determined, the moulded depth shall be measured to a line of reference extending from the lower part of the deck along a line parallel with the raised part.
12 Novel life-saving appliance or arrangement is a life-saving appliance or arrangement which embodies new features not fully covered by the provisions of this chapter but which provides an equal or higher standard of safety.
13 Rescue boat is a boat designed to rescue persons in distress and to marshal survival craft.
14 Retrieval is the safe recovery of survivors.
15 Retro-reflective material is a material which reflects in the opposite direction a beam of light directed on it.
16 Short international voyage is 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. Neither the distance between the last port of call in the country in which the voyage begins and the final port of destination nor the return voyage shall exceed 600 miles. The final port of destination is the last port of call in the scheduled voyage at which the ship commences its return voyage to the country in which the voyage began.
17 Survival craft is a craft capable of sustaining the lives of persons in distress from the time of abandoning the ship.
18 Thermal protective aid is a bag or suit made of waterproof material with low thermal conductivity.
1 Except as provided in paragraphs 5 and 6, life-saving appliances and arrangements required by this chapter shall be approved by the Administration.
2 Before giving approval to life-saving appliances and arrangements, the Administration shall ensure that such life-saving appliances and arrangements:
.1 are tested, to confirm that they comply with the requirements of this chapter, in accordance with the recommendations of the Organization:*
.2 have successfully undergone, to the satisfaction of the Administration, tests which are substantially equivalent to those specified in those recommendations.
3 Before giving approval to novel life-saving appliances or arraignments, the Administration shall ensure that such appliances or arrangements:
.1 provide safety standards at least equivalent to the requirements of this chapter and have been evaluated and tested
