BOG RECEPTION CONTROL METHOD AND ITS DEVICE FOR LNG SHIP IN LNG RECEIVING BASE

摘要

PROBLEM TO BE SOLVED: To receive BOG in an LNG ship tank in a land side LNG tank in a stable state without influence of a receiving pipe line length of the BOG or a design pressure of the land side LNG tank or the like in an LNG receiving base. SOLUTION: The BOG in the LNG ship tank ST is sent to the land side LNG tank LT through return gas piping by a land side compressor (RGB) 10 for returning return gas. Pipe line changing means (valves 35, 50 or the like) is provided to selectively form a line for returning the BOG in the land side LNG tank LT into the LNG ship tank ST and a line for force feeding the BOG in the LNG ship tank ST into the land side LNG tank LT.
