  "text": "(1) In every vessel of 24.4 metres in length and over to which these Rules apply where oil for lubrication, cooling or operation of the main propelling machinery, gearbox and its ancillary services is circulated under pressure, at least two pumps shall be provided for the circulation of such oil where:—\n(a) the output or combined output of the main engine or engines exceeds 500 b.h.p.; or\n(b) lubricating oil under pressure is the only means of control of machinery for the propulsion and safety of the vessel.\nEach pump shall be adequate for circulating the lubricating oil. Only one pump shall be required for an emergency generator.\n(2) In every such vessel strainers which can be cleaned without interrupting the supply of such oil shall be provided.\n(3) In every such vessel provision shall be made to prevent overpressure and to indicate proper operation in every part of the system. Where the means of preventing overpressure is a relief valve it shall be in a closed circuit.\n(4) In every such vessel flexible pipes in lubricating oil, cooling oil and hydraulic systems shall be fit for their intended service.\n(5) In every such vessel oil level indicators in lubricating oil, cooling oil and hydraulic systems shall be accurate and fit for their intended service and shall be of a type which does not require piercing of the lower part of the tank. Tubular gauge glasses shall not be fitted to lubricating oil or hydraulic oil tanks but suitably protected gauges having flat glasses of substantial thickness and self-closing fittings may be used.\n(6) In every such vessel oil pressure pipes in lubricating oil, cooling oil and hydraulic systems shall be made of seamless steel, or other suitable material having flanged joints and shall be properly installed and be led at such a height above the inner bottom as will facilitate inspection and repair. Every such pipe, joint and its fittings other than pipes, joints and fittings in hydraulic control systems, shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to 2.8 kilogrammes force per square centimetre or to twice the maximum working pressure, whichever is the greater, and shall at any time thereafter be capable of withstanding such a test.\n(7) In every such vessel oil pipes in lubricating oil, cooling oil and hydraulic systems, not being oil pressure pipes, shall be made of steel or other suitable material having flanged joints and shall be properly installed and be led at such a height above the inner bottom as will facilitate inspection and repair. Every such pipe, joint and its fittings other than pipes, joints and fittings in hydraulic control systems, shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to 2.8 kilogrammes force per square centimetre or to twice the maximum working pressure, whichever shall be the greater, and shall at any time thereafter be capable of withstanding such a test.",
