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.
