[接上页] ．４作为包括本条之２．１至２．３规定的门的替代关闭的风雨密坡道。 如果船舶在停泊时某个门不能开启或关闭，则在该船靠近或拖离停泊地时，该门可以开启或让其开着，但尽可能应使该门能迅速被操纵。在任何情况下，船首内侧门必须保持关闭状态。 ３不管本条之２．１和２．４的要求如何，当船舶位于安全锚地，若其安全不受妨碍，则如因船舶操作或旅客上下船特殊情况所需要的门，主管机关可以授权船长酌定开启。 ４船长应确保对本条之２所述门的关闭和开启进行监视和报告的有效制度的执行。 ５在船舶进行任何航行之前，船长应确保把最后关闭本条之２所述门的时间和按照本条之３开启任何特殊情况门的时间，依照第Ⅱ－１／２２条的要求记录在航海日志上。 ３第Ⅱ－１章第２２条客船和货船的稳性资料 下列新的本条之３加在现有本条之２之后：“３对所有客船，定期间隔不超过５年，应进行空船重量检验，以核查空船排水量和重心纵向位置的任何变化。与认可的稳性资料相比较，如果空船排水量的偏差超过２％，或重心纵向位置的偏差超过１％Ｌ，则该船应重做倾斜试验。” 下列文字加在现有本条之３中“姐妹船”之后： “按本条之１要求”。 现有本条之３和４改编号为本条之４和５。 AMENDMENT TO THE INTERNATIONAL CONVENTION FOR THE SAFETYOFLIFEATSEA, 1974 ([Adopted on 28 October 1988 by Resolution MSC. 12(56)]) Whole document TABLE OF CONTENTS Amendment to Chapter II-1, Regulation 8 Stability of passenger ships in damaged condition Addition of Chapter II-1, new Regulation 20-1 Closure of cargo loading door Amendment to Chapter II-1, Regulation 22 Stability information for passenger ships and cargo ships AMENDMENTS TO THE INTERNATIONAL CONVENTION FOR THE SAFETY OF LIFE AT SEA, 1974 [Adopted on 28 October 1988 by Resolution MSC. 12(56)] 1 Chapter II-1, Regulation 8 Stability of passenger shipsinda-maged condition The following text is inserted after the title: "(Paragraphs 2.3, 2.4, 5 and 6.2 apply to passenger ships constructed on or after 29 April 1990 and paragraphs 7.2, 7.3 and 7.4 apply to all passenger ships)" The existing text of paragraph 2.3 is replaced by the following: "2.3 The stability required in the final condition after damage, and after equalization where provided, shall be determined as follows: 2.3.1 The positive residual righting lever curve shall have a minimum range of 15° beyond the angle of equilibrium. 2.3.2 The area under righting lever curve shall be at least 0.015 m-rad, measured from the angle of equilibrium to the lesser of: .1 the angle at which progressive flooding occurs; .2 22° (measured from the upright) in the case of one-compartment flooding, or 27° (measured from the upright) in the case of the simultaneous flooding of two or more adjacent compartments. 2.3.3 A residual righting lever is to be obtained within the range specified in 2.3.1, taking into account the greatest of the following heeling moments: .1 the crowding of all passengers towards one side; .2 the launching of all fully loaded davit-launched survival craft on one side; .3 due to wind pressure;as calculated by the formula: heeling moment GZ(in metres) = --------------- + 0.04 displacement However, in no case is this righting lever to be less than 0.10m. 2.3.4 For the purpose of calculating the heeling moments in paragraph 2.3.3, the following assumptions shall be made: .1 Moments due to crowding of passengers: 1.1 4 persons per square metre; 1.2 a mass of 75 kg for each passenger; 1.3 passengers shall be distributed on available deck areas towards one side of the ship on the decks where muster stations are located and in such a way that they produce the most adverse heeling moment. .2 Moments due to launching of all fully loaded davit-launched survival craft on one side: .2.1 all lifeboats and rescue boats fitted on the side to which the ship has heeled after having sustained damage shall be assumed to beswung out fully loaded and ready for lowering; .2.2 for lifeboats which are arranged to be launched fully loaded from the stowed position,the maximum heeling moment during launching shall be taken; .2.3 a fully loaded davit-launched liferaft attached to each davit on the side to which the ship has heeled after having sustained damage shall be assumed to be swung out ready for lowering; .2.4 persons not in the life-saving appliances which are swung out shall not provide either additional heeling or righting moment; .2.5 life-saving appliances on the side of the ship opposite to the side to which the ship has heeled shall be assumed to be in a stowedposition. .3 Moments due to wind pressure: .3.1 a wind pressure of 120 N/square mto be applied; .3.2 the area applicable shall be the projected lateral area of |
