Method of loading and unloading liquefied petroleum gas from marine vessel uses rigid frame mounted on ocean bed and supporting beam pivotally supporting hoses to supply gas to vessel

摘要

The method involves attaching the vessel to a rigid mooring mast with an upper beam (7) pivotally mounted on a rigid sub sub-sea frame (1). It involves transferring the gas by flexible hoses forming articulated arms to the vessel via a discharge hose (14) mounted on the rigid frame, or by a cryogenic coupling (16). The gas is fed from the discharge hose supported by the beam to a side terminal via the undersea hoses. An Independent claim is included for a loading and unloading feed using the method
