多看些规范就知道了,下面是ABS 关于油舱测深管的规定。
11.3.7 Sounding Pipes of Fuel Oil and Lubricating Oil Tanks
Sounding pipes from fuel oil tanks are not to terminate in any spaces where a risk of ignition of
spillage exists. In particular, they are not to terminate in passenger or crew spaces, in machinery
spaces or in close proximity to internal combustion engines, generators, major electric equipment
or surfaces with temperature in excess of 220°C (428°F). Where this is not practicable, the following
are to be complied with.
11.3.7(a) Fuel oil tanks. Sounding pipes from fuel oil tanks may terminate in machinery spaces
provided that the following are met:
i) The sounding pipes are to terminate in locations remote from the ignition hazards, or
effective precautions, such as shielding, are taken to prevent fuel oil spillage from coming
into contact with a source of ignition.
ii) The termination of sounding pipes is fitted with a quick-acting self-closing valve and with
a small diameter self-closing test cock or equivalent located below the self-closing valve
for the purpose of ascertaining that fuel oil is not present before the valve is opened.
Provisions are to be made to prevent spillage of fuel oil through the test cock from
creating an ignition hazard.
iii) (2005) A fuel oil level gauge complying with 4-6-4/13.5.6(b) is fitted. However, short
sounding pipes may be used for tanks other than double bottom tanks without the
additional closed level gauge, provided an overflow system is fitted. See 4-6-4/13.5.4.
11.3.7(b) Lubricating oil tanks. Sounding pipes from lubricating oil tanks may terminate in
machinery spaces provided that the following are met:
i) The sounding pipes are to terminate in locations remote from the ignition hazards, or
effective precautions, such as shielding, are taken to prevent oil spillage from coming into
contact with a source of ignition.
ii) (2005) The termination of sounding pipes is fitted with a quick-acting self-closing gate
valve. Alternatively, for lubricating oil tanks that cannot be filled by a pump, the sounding
pipes may be fitted with an appropriate means of closure, such as a shut-off valve or a
screw cap attached by chain to the pipe. |
