You are to load a cargo of Cyclohexanol to tanks 2, 3 and 4 centre and 2 and 4 wing tanks. The lines to these tanks are all connected at the manifold with flexible hoses and are all capable of being isolated with the exception of 2 centre, which has therefore been designated as the last tank to load. What will you do with the other tanks as they complete loading?
Close only the tank loading valves, so that pressure remains constant around the pipeline system and flexible hoses. Continue to monitor the cargo levels in the finished tanks to ensure that the high-level alarms are not activated as the ship's trim changes.
Close only the corresponding manifold cross-over valves as the tanks finish, so that the pressure in the lines equalises with the pressures in the tanks. Re-check the ullages at the end of loading as they will have changed as the trim of the ship has changed.
Close the tank loading valves, then close the appropriate manifold cross-over valves. After a few minutes, re-open the tank loading valves and leave them like this until cargo operations are completed, to ensure they drain fully. Re-check the ullages at the end of loading and then close the tank loading valves.
Close the appropriate manifold cross-over valves and tank loading valves as each tank finishes. Continue to monitor the cargo levels in the finished tanks to ensure that the valves are not passing.

Why is is especially necessary to continue to ventilate the tank and to continuously monitor the atmosphere when working inside a cargo compartment which still contains vegetable oil residues?
For a tank which has contained vegetable oils, if it is continuously ventilated an Enclosed Space Entry Permit is not required. However, for anyone entering the compartment without a permit in place, they must carry an oxygen meter which continuously monitors the atmosphere.
Forced ventilation will create a hard "skin" on the residues, making them safer to stand on. Testing the atmosphere will indicate when this skin has formed, as no further vapours will be released.
Vegetable oils are commonly washed using very hot water. Forced ventilation will make the temperature inside the compartment better to work in. Monitoring the atmosphere will indicate if the humidity is increasing.
Because the decomposing residues continue to release hazardous gases, reducing the levels of oxygen in the tank and making the atmosphere potentially dangerous.
