[接上页] (2) Where any part of the ship below the waterline extends forward of the forward perpendicular, the distances specified in subregulation (1) shall be measured from a point either- (a) at the mid point of the maximum length forward of the forward perpendicular of such an extension; or (b) at a horizontal distance forward of the forward perpendicular equal to 1.5% of the length of the ship; or (c) at a horizontal distance 3.0 metres forward of the forward perpendicular,whichever gives the smallest measurement. (3) Where bow doors are fitted and a sloping loading ramp forms part of the extension of the collision bulkhead above the bulkhead deck, any part of the ramp structure which is more than 2.3 metres above the bulkhead deck may extend forward of the limit specified in subregulation (1) as amended in subregulation (2), if applicable. The ramp shall form a complete weathertight closure of the collision bulkhead extension above the bulkhead deck. (4) Every such ship shall be provided with a watertight afterpeak bulkhead and with watertight bulkheads dividing the space appropriated to the main and auxiliary propelling machinery and boilers, if any, from other spaces. Such bulkheads shall be watertight up to the bulkhead deck, provided that the afterpeak bulkhead may be stopped below the bulkhead deck if the safety of the ship as regards subdivision is not thereby impaired. (5) The stern gland of every such ship shall be situated in a watertight shaft tunnel or other watertight space separate from the stern tube compartment and of such a volume that if the tunnel or space is flooded the margin line will not be submerged. The stern tube shall be enclosed in a watertight compartment, the volume of which shall be the smallest compatible with the proper design of the ship. (Enacted 1991) Cap 369AM reg 8 Double bottoms (1) Subject to the provisions of this regulation every ship of Classes I, II, II(A) shall be fitted with a watertight double bottom which shall extend from the forepeak bulkhead to the afterpeak bulkhead, provided that the Director may permit a double bottom to be dispensed with in compartments where its fitting would not be compatible with the design and proper working of the ship, subject to compliance with the following minimum requirements for fitting such a double bottom- (a) in ships of 50 metres but less than 61 metres in length, from the forward bulkhead of the machinery space to the collision bulkhead or as near to that bulkhead as is practicable; (b) in ships of 61 metres but less than 76 metres in length, from the collision bulkhead to the afterpeak bulkhead or as near to those bulkheads as is practicable, but not necessarily in the machinery space; (c) in ships of 76 metres in length or over a double bottom shall be fitted amidships and shall extend from the collision bulkhead to the afterpeak bulkhead or as near to those bulkheads as is practicable.(2) The Director may exempt any ship of Class II or II(A) from the requirements of a double bottom in any portion of the ship which is subdivided by application of a factor of subdivision not exceeding .50, if he is satisfied that the fitting of a double bottom in that portion of the ship would not be compatible with the design and proper working of the ship. (3) When a double bottom is required by this regulation to be fitted in a ship, its moulded depth in millimetres measured at the centre line shall be not less than 406 plus 4.17 times the length of ship in metres and the inner bottom shall be continued out to the ship's sides in such a manner as to protect the bottom to the turn of the bilge. The inner bottom shall be deemed to be adequate for this purpose if the line of intersection of the outer edge of the margin plate with the bilge plating is not lower at any point than a horizontal plane passing through the point of intersection with the frame line amidships of a transverse diagonal line inclined at 25 degrees to the base line and cutting it at a point one-half of the ship's moulded breadth from the centre line. (4) Wells constructed in the double bottom for the purpose of drainage shall not be larger nor extend downwards more than is necessary for such purpose. The depth of the well shall in no case be more than the depth of the double bottom at the centre line, less 460 millimetres, nor shall the well extend below the horizontal plane referred to in subregulation (3), provided that a well extending to the outer bottom may be constructed at the after end of a watertight shaft tunnel fitted in accordance with regulation 7(5). (5) Wells for purposes other than drainage shall not be constructed in the double bottom. The Director may exempt any ship from the requirement of this subregulation in respect of any well which he is satisfied will not diminish the protection given by the double bottom. (6) Nothing in this regulation shall require a double bottom to be fitted in way of watertight compartments of moderate size used exclusively for the carriage of liquids, if the safety of the ship will not be impaired in the event of bottom or side damage by reason of the absence of a double bottom in that position. |
