Location of Cargo Pumps: Cargo pumps are to be located on deck, in the cargo tanks or in special pump rooms separated from other ship's spaces by gastight decks and bulkheads.
Pump rooms shall be accessible only from the cargo area and shall not be connected to engine rooms or spaces which contain sources of ignition.
Penetrations of pump room bulkheads by shafts are to be fitted with gastight seals.
Provision shall be made for lubricating the seals from outside the pump room.
Cargo equipments
Overheating of the seals and the generation of sparks are to be avoided by appropriate design and the choice of suitable materials.
Where steel bellows are used in gastight bulkhead penetrations, they are to be subjected to a pressure test at 5 bar prior to fitting.
Cargo equipments
Suitable arrangements are to be provided for cargo pumps to prevent damage due to over pressure.
It shall be possible to control the capacity of the cargo pumps both from the pump room and from a suitable location outside this room.
Means are to be provided for stopping cargo pumps from a position above the tank deck.
At all pump operating positions and cargo handling positions on deck, pressure gauges for monitoring pump pressures are to be fitted.
The maximum permissible working pressure is to be indicated by a red mark on the scale.
The drain pipes of steam-driven pumps and steam lines shall terminate at a sufficient height above the bilge bottom to prevent the ingress of cargo residues.
