Note :



Cargo loading is an operation not fully under the control of the ship because the transfer of cargo to the ship is managed by the shore terminal.

Loading rate

Commencement of loading should be at a slow rate until it has been verified that the cargo is being loaded into the correct tanks, that there are no leaks in the system and that all monitoring systems are functioning correctly.

Checks during loading

At regular intervals throughout the operation, checks should be made to ensure that the cargo is not leaking and that tanks are being loaded according to the agreed transfer plan. Remote read outs from tanks should be checked for accuracy by utilising the closed gauging equipment.

High level alarms and tank overflow control alarms are safety critical items, and loading should bestopped if it is suspected that either is not working correctly.
