Unloading of tanker of LNG in the shallow waters

摘要

"Unloading of tanker of LNG in shallow waters.A system for unloading LNG (liquefied natural gas) of a tanker (26) in shallow waters, for gasification.Or heating the LNG unloaded for the production of gaseous hydrocarbons, or a gas for pressurization of the gas, and the gas flow to a ground station (56).It includes a structure that is fixed to the bottom of the sea, and protrudes above the surface of the sea and help in mooring the tanker.In a system, the structure is fixed to the bottom of the sea is a largely cylindrical tower (12) with a fork mooring (20) mounted in pivoting at its upper end.A floating structure (14) such as a boring that moves with the wind and the tides, has one end connected to the pivoting bow shape to a distal end of the fork.So that the boring is kept near the tower, but can drift around the tower with the winds, waves and currents changing.The tanker is moored to the tower so that the boring and the tanker form a combination that moves with the wind and the tides as a combination.A device for gasification and pressurization (32, 34) for heating and pressurization of the LNG, and any crew cabins (36) are all located in the boring.In such a way that a tower of low cost can be used. In another system, the structure is a Breakwater (180).
