[接上页] (4) Openings closed by sluice valves are not permitted in the watertight subdivision bulkheads. Cap 369C reg 30 Pipes, etc., through bulkheads Where pipes, electric cables, etc., pass through the main transverse bulkheads, arrangements shall be made to ensure that the watertightness of the bulkheads is not impaired. (See paragraph 122 (f)). Cap 369C reg 31 Means for closing openings The arrangement and efficiency of the means for closing each opening in watertight bulkheads shall be consistent with its intended purpose and with the position in which it is fitted, and shall be generally to the satisfaction of the Surveyor of Ships. Watertight doors fitted in bulkheads between permanent and reserve bunkers shall always be accessible except as provided in paragraph 41(5)(c). Watertight doors shall comply with the following requirements. Cap 369C reg 32 Types of doors (1) The only types of watertight doors permissible are hinged doors and sliding doors. (2) A sliding door may have a horizontal or vertical motion. If required to be hand operated only, the gearing shall be capable of being worked at the door itself and also at an accessible position above the bulkhead deck. Cap 369C reg 33 Classes of watertight doors The permissible classes of doors are: Class 1.-Hinged doors fitted with catches workable from each side of the bulkhead. Class 2.-Sliding doors operated by hand gear only. Class 3.-Sliding doors with brass rubbing faces operated by hand gear only. Class 4.-Sliding doors with brass faces operated by a releasing arrangement above the bulkhead deck as described in paragraph 35, and by hand gear. Class 5.-Sliding doors with brass rubbing faces operated by power from a central control, as described in paragraph 36, and by hand gear. Cap 369C reg 34 Hand gear for watertight doors The mechanism required for closing sliding watertight doors by hand from above the bulkhead deck shall be expeditious in its action and sufficiently powerful to be capable of closing the door under unfavourable circumstances. The operating gear shall be accessible in all cases. It should, if possible, consist of a crank handle or a wheel and handle, and be permanently attached to the shafting so as to be always ready for use. If this cannot be done, the handle or wheel must be stowed immediately alongside the working position. There shall be an index at the operating position showing whether the door is open or closed. The lead of shafting to the door should be as direct and free from complications as possible. All screws, rods and other apparatus for raising and lowering watertight doors must be provided with proper lubrication, and guarded where necessary. Cap 369C reg 35 Doors which close by their own weight If a door is required to be closed by dropping or by the action of a dropping weight, it shall be fitted with a suitable arrangement to regulate the closing movement and the gearing shall be so arranged that the door can be released both at the door itself and at an accessible position above the bulkhead deck. Hand gear shall also be provided, so arranged as to operate at the door itself and above the bulkhead deck, and also so that, after being disengaged for dropping, it can be quickly re-engaged from either the upper or the lower position. If the surveyor is of opinion that there is danger of persons being injured while passing through a doorway in a bulkhead owing to the door being of a quick-closing type, or for any other reason, a report of all the circumstances should be forwarded to the Principal Surveyor of Ships before a declaration is issued. Cap 369C reg 36 Doors which close by power If a door is required to be power operated from a central control, the gearing shall be so arranged that the door can be operated by power also at the door itself. The arrangement shall be such that the door will close automatically if opened by the local control after being closed from the central control, and also such that any door can be kept closed by local arrangements which will prevent that door from being opened from the central control. Such power operated doors shall be provided with hand gear, workable both at the door itself and from an accessible position above the bulkhead deck. The arrangements shall comply with the following conditions- The power shall always be available at sea and ample for working the doors. The source of power shall be in duplicate, each power unit being sufficient to work the whole of the doors. An indicator shall be fitted at the central control station showing when power is available, and it shall be possible to close all the power worked doors practically simultaneously. The fluid used in a hydraulic system shall be a non-freezing mixture when low temperatures are likely to be encountered. The hand operating gear required to be fitted in connection with power-worked doors should be permanently attached to the doors unless satisfactory means are provided for speedily and reliably engaging it from above the bulkhead deck. In any case it should be seen that when the power is shut off there is no danger of vertical doors dropping, and the arrangements shall be such that, in the event of the power failing, the working of the hand gear on doors worked by hydraulic power will not be prevented or hindered by water-lock in the power or closing gear pipe. |
