LIQUID CARGO HANDLING EQUIPMENT
The movement of liquid bulk cargo, crude oil and derivatives, from the tanker is
undertaken by means of pipelines connected to the shore-based storage tanks.
Pumping equipment is provided in the tanker storage plant or refinery ashore, but
not on the quayside. In view of the dangerous nature of such cargo, it is common
practice to build the special berths a small distance from the main dock system on
the seaward side. Oil cargo is discharged from the ship’s tanks, via the cargo
piping system to the main ship’s manifold usually situated amidships, on either
port or starboard side. From there by means of shore-based loading arms oil is
transferred to the shore manifold and is then distributed to shore-based storage
tanks on the oil terminal. The loading arm hose must be flanged oil-tight to the
ship’s manifold so that oil spills can be avoided.
