Discharge of Machinery Space Bilges into Slop Tank
When bilge pumps in the machinery space are arranged to discharge into a cargo slop tank, the discharge piping is to be arranged as follows:
i) The discharge line is to enter the cargo slop tank from the weather deck through the tank top.
ii) The tank penetration is to be located as close to a vertical tank boundary as practicable.
iii) Within the tank, to prevent the free fall of liquid, the discharge line is to be as short as practicable and the outlet is to be arranged to discharge against the vertical boundary.
iv) (2012) A stop-check valve is to be provided in the discharge line and is to be located either within the machinery space or immediately outside of the machinery space, and as close to the machinery space bulkhead as possible.
v) (2006) In order to prevent cargo vapor from entering the machinery spaces, a loop seal is to be provided in the discharge line. This loop seal is to be located outside the machinery space, and preferably, in the cargo pump room. The height of the loop seal is to provide a static head greater than the pressure setting of the cargo slop tank pressure/vacuum valve, or a minimum of 762 mm (30 in.), whichever is greater. A means is to be provided to prevent the loop seal from freezing where exposed to the weather.
vi) A non-return valve is to be located in the discharge line on deck as close to the tank penetration as practicable. |
