[接上页] (b) If the margin line may become submerged during the flooding assumed for the purposes of the calculation referred to in Schedule 3, the construction of the ship shall be such as will enable the master of the ship to ensure- (i) that the maximum angle of heel during any stage of such flooding will not be such as will endanger the safety of the ship; and (ii) that the margin line will not be submerged in the final stage of flooding.(4) (a) There shall be provided by the owner in every such ship a document for the use of the master of the ship containing information as to the use of any cross-flooding fittings provided in the ship. (b) There shall be provided by the owner in every ship of Class I, Class II or Class II(A) a document for the use of the master of the ship containing the following additional information- (i) information necessary for the maintenance of sufficient intact stability under service conditions to enable the ship to withstand damage to the extent referred to in Schedule 3; and (ii) information as to the conditions of stability on which the calculations of heel have been based, together with a warning that excessive heeling might result should the ship sustain damage when in a less favourable condition. (Enacted 1991) Cap 369AL reg 12 Ballasting In every ship to which this Part applies, when ballasting with water is necessary, the water ballast shall 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 Director shall be fitted, or an alternative means acceptable to him shall be provided for disposing of the oily-water ballast. (Enacted 1991) Cap 369AL reg 13 Construction of watertight bulkheads, etc. (1) In every ship to which this Part applies every portion of the ship required by these regulations to be watertight shall be constructed in accordance with such of the requirements of Schedule 4 as apply to it. (2) In every such ship all tanks forming part of the structure of the ship and used for the storage of oil fuel or other liquids including double bottoms, peak tanks, settling tanks and bunkers shall be of a design and construction adequate for that purpose. (Enacted 1991) Cap 369AL reg 14 Openings in watertight bulkheads, etc. (1) In every ship of Class I, Class II or Class II(A) the number of openings in bulkheads and other structures required by these regulations to be watertight shall be the minimum compatible with the design and proper working of the ship. (2) So far as practicable, trunks installed in connection with ventilation, forced draught or refrigeration systems in any such ship shall not pierce such bulkheads or structures. (3) Every tunnel above the double bottom, if any, in such a ship whether for access from the crew space to the machinery space, for piping or for any other purpose, which passes through such a bulkhead shall be watertight. The means of access to at least one end of such tunnel, if it may be used as a passage at sea, shall be through a trunkway extending watertight to a height sufficient to permit access above the margin line. The means of access to the other end of the tunnel shall be through a watertight door. No tunnel shall extend through the first subdivision bulkhead abaft the collision bulkhead. (4) Within spaces containing the main and auxiliary propelling machinery including boilers serving the needs of propulsion and all permanent bunkers, not more than one doorway, apart from the doorways to bunkers and shaft tunnels, may be fitted in each main transverse bulkhead. Where 2 or more shafts are fitted, the tunnels shall be connected by an inter-communicating passage. There shall be only one doorway between the machinery space and the tunnel spaces where one or 2 shafts are fitted and only 2 doorways where there are more than 2 shafts. All such doorways shall be located so as to have their sills as high as practicable. (5) Doorways, manholes and access openings shall not be fitted in the collision bulkhead below the margin line of any such ship or in any other bulkhead which is required by these regulations to be watertight and which divides a cargo space from another cargo space or from a permanent or reserve bunker: Provided that the Director may permit any such ship to be fitted with doorways in bulkheads dividing 2 between-deck cargo spaces if he is satisfied that- (a) the doorways are necessary for the proper working of the ship; (b) the number of such doorways in the ship is the minimum compatible with the design and proper working of the ship, and they are fitted at the highest practicable level; and (c) the outboard vertical edges of such doorways are situated at a distance as far as practicable from the ship's shell plating and in no case less than one-fifth of the breadth of the ship such distance being measured at right angles to the centre line of the ship at the level of the deepest subdivision load water line.(6) In every ship of Class I, Class II or Class II(A) bulkheads outside the spaces containing machinery which are required by these regulations to be watertight shall not be pierced by openings which are capable of being closed only by portable bolted plates. |
