[接上页] (a) the material of which it is constructed; (b) the service for which it is intended; and (c) the type of engines by which it is driven or of which it forms a part. (Enacted 1991) Cap 369R reg 25 Boiler feed systems (1) In every ship to which these regulations apply every boiler which provides services essential for the safety of the ship and which could be rendered dangerous by the failure of its feed water supply shall be provided with not less than two efficient and separate feed water systems so arranged that either of such systems may be opened for inspection or overhaul without affecting the efficiency of the other. Means shall be provided which will prevent overpressure in any part of the systems. (2) If in any such ship it is possible for oil to enter the feed water system of a boiler, the arrangements for supplying boiler feed water shall provide for the interception of oil in the feed water. (3) Every feed check valve, fitting, or pipe through which feed water passes from a pump to such boilers in any such ship shall be designed and constructed to withstand the maximum working stresses to which it may be subjected, with a factor of safety which is adequate having regard to the material of which it is constructed and the working conditions under which it will be used. Every such valve, fitting, or pipe shall, before being put into service for the first time, be subjected to a hydraulic test suitably in excess of the maximum working pressure of the boiler to which it is connected or of the maximum working pressure to which the feed line may be subjected, whichever shall be the greater, and shall be maintained in an efficient condition. The feed pipes shall be adequately supported. (Enacted 1991) Cap 369R reg 26 Steam pipe systems (1) In every ship to which these regulations apply every steam pipe and every fitting connected thereto through which steam may pass shall be so designed and constructed as to withstand the maximum working stresses to which it may be subjected, with a factor of safety which is adequate having regard to- (a) the material of which it is constructed; and (b) the working conditions under which it will be used.(2) Without prejudice to the generality of the foregoing, every such steam pipe or fitting shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to a pressure suitably in excess of the working pressure to be determined having regard to the requirements of subregulation (1)(a) and (b) and every such steam pipe or fitting shall be maintained in an efficient condition. (3) Steam pipes shall be adequately supported. (4) Provision shall be made which will avoid excessive stress likely to lead to the failure of any such steam pipe or fitting, whether by reason of variation in temperature, vibration or otherwise. (5) Efficient means shall be provided for draining every such steam pipe so as to ensure that the interior of the pipe is kept free of water and that water hammer action will not occur under any condition likely to arise in the course of the intended service of the ship. (6) If in any ship to which these regulations apply a steam pipe may receive steam from any source at a higher pressure than it can otherwise withstand with an adequate factor of safety, an efficient reducing valve, relief valve and pressure gauge shall be fitted to such pipe. (Enacted 1991) Cap 369R reg 27 Air pressure systems (1) In every ship to which these regulations apply, being a ship in which machinery essential for the propulsion and safety of the ship or of persons on board is required to be started, operated or controlled solely by compressed air, there shall be provided an efficient air system which shall include a sufficient number of air compressors and compressed air storage vessels to ensure that an adequate supply of compressed air is available under all conditions likely to be met in service. (2) (a) In every such ship the parts of every such compressed air system other than a pneumatic control system which are subjected to air pressure shall be designed and constructed to withstand, with an adequate factor of safety, the maximum working stresses to which they may be subjected, and every air pressure pipe or fitting in such system shall, before being put into service for the first time, be subjected to a hydraulic test suitably in excess of the maximum working pressure to which it may be subjected and be maintained in an efficient condition. (b) Means shall be provided in any such ship to prevent overpressure in any part of any such compressed air system and, where water jackets or casings of air compressors and coolers might otherwise be subjected to dangerous overpressure due to leakage into them from air pressure parts, suitable pressure relief arrangements shall be provided. (c) Provision shall be made to reduce to a minimum entry of oil into any such air pressure system and to drain the system. Provision shall also be made to protect the system from the effects of internal explosion. |
