[接上页] the ship above the waterline corresponding to the intact condition; .3.3 the moment arm shall be the vertical distance from a point at one half of the mean draught corresponding to the intact condition to the centre of gravity of the lateral area." The following new paragraph 2.4 is added after the existing paragraph 2.3: "2.4 In intermediate stages of flooding, the maximum righting lever shall be at least 0.05 m and the range of positive righting levers shallbe at least 7°. In all cases, only one breach in the hull and only one free surface need be assumed." In the third sentence of paragraph 5 the phrase "as well as the maximum heel before equalization" is deleted. The following new sentence is added after the third sentence of paragraph 5: "The maximum angle of heel after flooding but before equalization shall not exceed 15°." The existing text of paragraph 6.2 is replaced by the following: "in the case of unsymmetrical flooding, the angle of heel for one-compartment flooding shall not exceed 7°. For the simultaneous flooding of two or more adjacent compartments, a heel of 12° may be permitted by the Administration." Existing paragraph 7 is renumbered as paragraph 7.1 The following new paragraphs 7.2, 7.3 and 7.4 are inserted after new paragraph 7.1: "7.2 The data referred to in paragraph 7.1 to enable the master to maintain sufficient intact stability shall include information which indicates the maximum permissible height of the ship''s centre of gravityabove keel (KG), or alternatively the minimum permissible metacentric height (GM), for a range of draughts or displacements sufficient to include all service conditions. The information shall show the influenceof various trims taking into account the operational limits. 7.3 Each ship shall have scales of draughts marked clearly at the bow and stern. In the case where the draught marks are not located where they are easily readable, or operational constraints for a particular trade make it difficult to read the draught marks, then the ship shall also befitted with a reliable draught indicating system by which the bow and stern draughts can be determined. 7.4 On completion of loading of the ship and prior to its departure, the master shall determine the ship''s trim and stability and also ascertain and record that the ship is in compliance with stability criteria in the relevant regulations. The Administration may accept the use of an electronic loading and stability computer or equivalent means for this purpose." 2 Chapter II-1, Regulation 20-1, newRegulation 20-1Closure of cargo loading door The following new regulation 20-1 is added after existing regulation 20. "Regulation 20-1 Closure of cargo loading doors 1 This regulation applies to all passenger ships. 2 The following doors, located above the margin line, shall be closed and locked before the ship proceeds on any voyage and shall remain closed and locked until the ship is at its next berth: .1 cargo loading doors in the shell or the boundaries of enclosed superstructures; .2 bow visors fitted in positions, as indicated in paragraph 2.1; .3 cargo loading doors in the collision bulkhead; .4 weathertight ramps forming an alternative closure to those defined in paragraphs 2.1 to 2.3 inclusive. Provided that where a door cannot be opened or closed or while the ship is at the berth such a door may be opened left open while the ship approaches or draws away from the berth, but only so far as may be necessary to enable the door to be immediately operated. In any case,the inner bow door must be kept closed. 3 Notwithstanding the requirements of paragraphs 2.1 and 2.4, the Administration may authorize that particular doors can be opened at the discretion of the master, if necessary for the operation of the ship or the embarking and disembarking of passengers, when the ship is at safe anchorage and provided that the safety of the ship is not impaired. 4 The master shall ensure that an effective system of supervision and reporting of the closing and opening of the doors referred to in paragraph 2, is implemented. 5 The master shall ensure, before the ship proceeds on any voyage, that an entry in the log-book, as required in regulation II-1/25, is made of the time of the last closing of the doors specified in paragraph 2 and the time of any opening of particular doors in accordance with paragraph3." 3 Chapter II-1, Regulation 22 Stability information for passengerships and cargo ships The following new paragraph 3 is added after existing paragraph 2: "3 At periodical intervals not exceeding five years, a lightweight survey shall be carried out on all passenger ships to verify any changesin lightship displacement and longitudinal centre of gravity. The ship shall be re-inclined whenever, in comparison with the approved stabilityinformation, a deviation from the lightship displacement exceeding 2% or a deviation of the longitudinal centre of gravity exceeding 1% of L is found or anticipated." The following words are added at the end of the first line of existing paragraph 3: "as required by paragraph 1." Existing paragraphs 3 and 4 are renumbered as paragraphs 4 and 5. |
