[接上页] (b) instructions concerning the operation of cross-flooding arrangements; and (c) all other data and aids which might be necessary to maintain stability after damage.(2) There shall be permanently exhibited, or readily available on the navigating bridge, for the guidance of the officer in charge of the ship, plans showing clearly for each deck and hold the boundaries of the watertight compartments, the openings therein with the means of closure and position of any controls thereof, and the arrangements for the correction of any list due to flooding. In addition, booklets containing the aforementioned information shall be made available by the owner of the ship for the use of the officers of the ship. (3) In providing the information referred to in subsection (1)(a) and determining the GM or KG values- (a) in the case where intact stability requirements are more onerous than the values referred to in paragraph (b), such requirements shall apply; (b) in the case where values determined from considerations solely related to the subdivision index are more onerous than such intact stability requirements- (i) the limiting GM values shall be varied linearly between the deepest subdivision load line and the partial load line; and (ii) for draughts below the partial load line, the GM value shall be assumed constant; and(c) in the case where values determined from both intact stability requirements and the subdivision index apply- (i) the limiting GM shall be varied linearly between the deepest subdivision load line and the partial load line; and (ii) for draughts below the partial load line, where the subdivision index is more onerous, the GM value shall be assumed constant and where the intact stability requirements are more onerous, such requirements shall apply.(4) Where there is a contravention of subsection (1) or (2), the owner of the ship commits an offence and is liable to a fine of $20000 and to imprisonment for 2 years. (Enacted 1992) Cap 369AT s 6 Openings in watertight bulkheads and internal decks PART IV INTERNAL OPENINGS (1) The number of openings in watertight subdivisions shall be kept to a minimum compatible with the design and proper working of the ship. Where penetrations of watertight bulkheads and internal decks are necessary for access, piping, ventilation, electrical cables, etc., arrangements shall be made to maintain the watertight integrity. The Certifying Authority may permit relaxation in the watertightness of openings above the freeboard deck, provided that it is demonstrated that any progressive flooding can be easily controlled and that the safety of the ship is not impaired. (2) Doors provided to ensure the watertight integrity of internal openings which are used while at sea shall be of the sliding watertight type and capable of being remotely closed from the bridge and also capable of being operated locally from each side of the bulkhead. Indicators shall be provided at the control position showing whether the doors are open or closed, and an audible alarm shall be provided at the door closure. The power, control and indicators shall be operable in the event of main power failure. Particular attention is to be paid to minimizing the effect of control system failure. Each power-operated sliding watertight door shall be provided with an individual hand-operated mechanism. It shall be possible to open and close the door by hand at the door itself from both sides. (3) Access doors and access hatch covers normally closed at sea, intended to ensure the watertight integrity of internal openings, shall be provided with means of indication locally and on the bridge showing whether these doors or hatch covers are open or closed. A notice shall be affixed to each such door or hatch cover to the effect that it is not to be left open. The use of such doors and hatch covers shall be authorized by the officer of the watch. (4) Watertight doors or ramps of satisfactory construction may be fitted to internally subdivide large cargo spaces, provided that the Certifying Authority is satisfied that such doors or ramps are essential. These doors or ramps may be hinged, rolling or sliding doors or ramps, but shall not be remotely controlled. Such doors or ramps shall be closed before the voyage commences and shall be kept closed during navigation; the time of opening such doors or ramps in port and of closing them before the ship leaves port shall be entered in the log book. Should any of the doors or ramps be accessible during the voyage, they shall be fitted with a device which prevents unauthorized opening. (5) Other closing appliances which are kept permanently closed at sea to ensure the watertight integrity of internal openings shall be provided with a notice which is to be affixed to each such closing appliance to the effect that it is to be kept closed. Manholes fitted with closely bolted covers need not be so marked. (6) Where a ship does not conform to any requirement in subsection (1), (2), (3), (4) or (5), the owner and master of the ship each commits an offence and is liable to a fine of $20000 and to imprisonment for 2 years. |
