(c) Where in any such ship the factor of subdivision required under paragraph 4 of Schedule 1 is 0.33 or less, the intact stability shall be adequate to withstand the flooding of any three adjacent main compartments.(3) For the purposes of this regulation the sufficiency of the intact stability of every such ship shall be determined in accordance with the provisions of Parts 1 and 3 of Schedule 3. (4) (a) Every ship shall be so constructed as to keep asymmetrical flooding, when the ship is in a damaged condition, at the minimum consistent with efficient arrangements. If cross-flooding fittings are provided in any such ship the fittings shall, where practicable, be self-acting but in any case where controls to cross-flooding fittings are provided, they shall be capable of being operated from above the bulkhead deck. Such fittings together with their controls shall be such as will not endanger the safety of the ship. The maximum angle of heel after flooding but before equalization shall not exceed 15 degrees. The cross-flooding fittings shall be capable of reducing the heel within 15 minutes, sufficiently to meet the requirements of paragraph 3(2) of Part 3 of Schedule 3. (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 but shall not exceed the maximum heel defined in paragraph 3(2) of Part 3 of Schedule 3; (ii) that the margin line shall not be submerged in the final stage of flooding.(5) There shall be provided by the owner in every ship, which is required by this Part to be subdivided, a document for the use of the master of the ship containing- (a) information as to the use of any cross-flooding fittings provided in the ship; (b) 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 Part 1 of Schedule 3; and (c) 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.This additional information shall be included in the stability information book. (L.N. 139 of 1994) Cap 369AM reg 12 Ballasting The arrangements for segregation of oil fuel and water ballast shall be in accordance with regulation 24 of the Merchant Shipping (Prevention of Oil Pollution) Regulations (App. I, p. K1). (Enacted 1991) Cap 369AM reg 13 Construction of watertight bulkheads, etc. (1) 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) 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 369AM reg 14 Openings in watertight bulkheads, etc. (1) (a) This regulation applies to every Hong Kong passenger ship to which these regulations apply except post 1992 ships. (L.N. 139 of 1994) (b) In every ship of Classes I, II and II(A) the number of openings in watertight bulkheads shall be reduced to the minimum compatible with the design and proper working of the ship and means shall be provided for closing these openings to the satisfaction of the Director. (L.N. 139 of 1994)(2) 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. (3) Within spaces containing the main and auxiliary propelling machinery including boilers serving the needs of propulsion and all permanent bunkers, not more that one doorway, apart from the doorway to 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 doorway between the machinery space and the tunnel spaces where one or two shafts are fitted and only two doorways where there are more than two shafts. All such doorways shall be located so as to have their sills as high as practicable. |
