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. As you complete loading in the tanks, you would:
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.
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.
Keep all valves open until all tanks are loaded.
Only monitor the ullages as the loading proceeds.
