SPLAS 中关于油舱侧深管终止在人员或机器处所的问题

2.2.3.5.1 Where sounding pipes are used, they shall not terminate in any space where the risk of ignition of spillage from the sounding pipe might arise. In particular, they shall not terminate in passenger or crew spaces. As a general rule, they shall not terminate in machinery spaces. However, where the Administration considers that these latter requirements are impracticable, it may permit termination of sounding pipes in

machinery spaces on condition that all of the following requirements are met:

.1 an oil-level gauge is provided meeting the requirements of paragraph 2.2.3.5.2;

.2 the sounding pipes terminate in locations remote from ignition hazards unless precautions are taken, such as the fitting of effective screens, to prevent the oil fuel in the case of spillage through the terminations of the sounding pipes from coming into contact with a source of ignition; and

.3 the terminations of sounding pipes are fitted with self-closing blanking devices and with a small-diameter self-closing control cock located below the blanking device for the purpose of ascertaining before the blanking device is opened that oil fuel is not present. Provisions shall be made so as to ensure that any spillage of oil fuel through the control cock involves no ignition hazard.

2.2.3.5.2 Other oil-level gauges may be used in place of sounding pipes subject to the following conditions:

.1 in passenger ships, such gauges shall not require penetration below the top of the tank and their

failure or overfilling of the tanks shall not permit release of fuel; and

.2 in cargo ships, the failure of such gauges or overfilling of the tank shall not permit release of fuel

into the space. The use of cylindrical gauge glasses is prohibited. The Administration may permit

the use of oil-level gauges with flat glasses and self-closing valves between the gauges and fuel

tanks.
