Abstract:
An apparatus for controlling the pressure in a cargo tank 1 supplies BOG generated from liquefied natural gas stored in the cargo tank 1 to a burning system 6 through a compressor. In this apparatus, a reliquefaction plant 5 is disposed on the downstream side of first and second compressors 3 and 4 and on the upstream side of the cargo tank 1 so that BOG discharged from the second compressor 4 is liquefied by the reliquefaction plant 5 and the liquefied fluid is returned again into the cargo tank 1.
