NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

The arrangements for the storage, distribution and utilisation of oil used in pressure lubrication systems shall be such as to ensure the safety of the ship and persons on board, and such arrangements in machinery spaces shall at least comply with the provisions of paragraphs .2.1, .2.4, .2.5, .2.6, .2.7, .2.8, .2.10 and .2.11, except that: this does not preclude the use of sight-flow glasses in lubricating systems provided that they are shown by test to have a suitable degree of fire resistance. If sight-flow glasses are used, the pipe shall be provided with valves in both ends. The valve at the lower end of the pipe shall be of a self-closing type; sounding pipes may be authorised in machinery spaces; the requirements of paragraphs .2.6.1.1 and .2.6.1.3 need not be applied on condition that the sounding pipes are fitted with appropriate means of closure. For ships constructed on or after 1 January 2003 the provisions of paragraph .10.2.5 shall also apply to lubricating oil tanks except those of having a capacity less than 500 litres, storage tanks on which valves are closed during the normal operation of the ship or where it is determined that the unintended operation of a quick closing valve on the lubricating oil tank would endanger the safe operation of the main propulsion and essential auxiliary machinery. The arrangements for the storage, distribution and utilisation of other flammable oils employed under pressure in power transmission systems, control and activating systems and heating systems shall be such as to ensure the safety of the ship and persons on board. In locations where means of ignition are present, such arrangements shall at least comply with the provisions of paragraphs .2.4, .2.6, .2.10 and .2.11 and with the provisions of paragraphs .2.7 and .2.8 in respect of strength and construction. In addition to the requirements of provisions .1 to .4, the oil fuel and lubricating oil systems shall comply with the following: where daily service oil fuel tanks are filled automatically, or by remote control, means shall be provided to prevent overflow spillages. Other equipment which treats flammable liquids automatically, e.g. oil fuel purifiers, which, whenever practicable, shall be installed in a special space reserved for purifiers and their heaters, shall have arrangements to prevent overflow spillages; where daily service oil fuel tanks or settling tanks are fitted with heating arrangements, a high temperature alarm shall be provided if the flashpoint of the oil fuel can be exceeded. Fuel oil, lubrication oil and other flammable oils shall not be carried in forepeak tanks.
