[接上页] (3) Stern Tubes and Glands: In all cases stern tubes shall be enclosed in watertight spaces. The stern gland shall be situated within a watertight shaft tunnel or other space of such volume that if flooded by leakage through the stern gland the margin line will not be submerged. The height and width of the watertight tunnel or compartment shall be sufficient at every part to allow proper attention being given to shaft couplings, bearings, etc., within the space. When the tunnels or their equivalent form part of the scheme of subdivision of a ship they shall be constructed as required by paragraphs 17 to 25. Cap 369C reg 15 Double bottoms (1) Longitudinal Extent: (a) In ships 200 feet and under 249 feet in length a double bottom shall be fitted at least from the machinery space to the fore peak bulkhead, or as near thereto as practicable. (b) In ships 249 feet and under 330 feet in length a double bottom shall be fitted at least outside the machinery space, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable. (c) In ships 330 feet in length and upwards a double bottom shall be fitted amidships, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable.(2) Transverse Extent: (a) Where a double bottom is required to be fitted 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 bilge. (b) Such protection will be deemed satisfactory if the line of intersection of the outer edge of the margin plate with the bilge plating is not lower at any part than a horizontal plane passing through the point of intersection with the frame fine amidships of a transverse diagonal line inclined at 25 degrees to the base fine and cutting it at a point one-half the ship's moulded breadth from the middle line.(3) Wells in Inner Bottom: Wells constructed in the double bottom in connection with the drainage arrangements shall not extend downwards more than necessary, nor shall they be less than 18 inches from the outer bottom or from the inner edge of the margin plate. A well extending to the outer bottom is, however, permitted at the after end of the shaft tunnel of screw ships. (4) Means of Access-Protection of Air and Sounding Pipes: The inner bottom must only be pierced for such manholes as are necessary for access and must be fitted with efficient covers having such arrangements as will secure effective watertight joints. All air and sounding pipes are to be effectively protected against risk of damage from cargo, coal, etc. (See paragraphs 124, 260 and 261). Cap 369C reg 16 Assigning, marking and recording of subdivision load-lines (1) (a) In order that the required degree of subdivision shall be maintained, a load-line, corresponding to the approved sub-division draught is to be assigned and marked on the ship's sides. (b) Ships having spaces which are adapted for the accommodation of passengers and the carriage of cargo alternatively may have, if the owners desire, one or more additional load-line marks corresponding to the subdivision draughts approved for the alternative conditions. (c) The positions of the subdivision load-lines and the conditions under which they apply shall be determined in every case by a Surveyor of Ships.(2) The subdivision load-lines assigned and marked under the foregoing provisions shall be recorded in the Safety Certificate, and shall be distinguished by the notation C.1 for the principal passenger condition, and C.2, C.3, etc., for the alternative conditions. (3) The freeboard corresponding to each of these loadlines inserted in the Safety Certificate shall be measured at the same position and from the same deck line as the freeboards determined by the Load Line Rules. (4) In no case shall any subdivision loadline mark be placed above the deepest loadline in salt water as determined by the strength of the ship and/or the Load Line Rules. (5) As regards inspection of subdivision loadlines, see paragraph 1(5)(d). Cap 369C reg 17 Strength and construction Construction and Scantlings of Watertight Bulkheads, Decks, Recesses, Trunks, Tunnels, Inner Skins and Oil Fuel Tanks All watertight bulkheads, decks, recesses, etc., forming part of the subdivision arrangements should be of such strength and so constructed as to be capable of supporting with a proper margin of resistance, the pressure due to a head of water up to the margin line. Cap 369C reg 18 Watertight transverse bulkheads (1) Plating: Transverse bulkheads shall be watertight up to the bulkhead deck, and shall have plating of not less thickness than required by Table 4, Appendix II. Where a transverse bulkhead is at the end of a stokehold space, the lower part of the bulkhead plating to a height of at least 24 inches above the stokehold floor, shall be at least .1 inch thicker than given by the Table. Where a transverse bulkhead is at the end of a bunker space, the lowest strake shall be at least 36 inches high and .1 inch thicker than given by the Table. In all other cases the lowest strake shall be at least .04 inch thicker, except that any limber plates shall be .1 inch thicker. |
