Ship- loading and unloading facilities
Facilities for loading and unloading inland and seagoing vessels and the jetty are designed based on the local conditions.
Transfer stations are articulated steel tube loaders or hose safety systems with drift protection and disconnecting devices to prevent product from being discharged into the water.
The product is stored and removed through a combined system of manifolds to the tanks and the tanker respectively.
After each loading operation the relevant manifold is emptied by a residue discharge system.
Ship loading
The vessel is loaded from the involved tanks by the pumps of the tank farm via a calibrated and temperature-compensated measuring system. The measured values are logged automatically through loading computers and manually through tape printers.
Ship unloading
Unloading is effected by the vessel’s own pumps or stationary pumps on the jetty.
The measured values should be preferably logged by calibrated tank level meters because volumetric measuring devices require a more sophisticated design because of the high vapour quantities developing during the pump-out phase.
The hydrocarbon vapours developing during the loading operation can be returned to a vapour recovery system involving the tanks.
