FIELD: vessels and other watercrafts.
SUBSTANCE: invention relates to marine transport, in particular to a system and method for repeated liquefaction of stripping gas (BOG) formed in a vessel for storage on board, using stripping gas as a cooling agent. BOG re-liquefaction system for vessels comprises: multi-stage compressor, in which BOG is subjected to compression; heat exchanger, in which compressed by means of multistage BOG compressor is cooled by means of heat exchange with application of BOG as cooling agent, uncompressed by multi-stage compressor; pressure reducer arranged downstream of heat exchanger and reducing pressure of fluid medium cooled by means of heat exchanger; and bypass line, through which BOG is supplied to multistage compressor after bypass of heat exchanger.
EFFECT: invention allows minimizing loss of liquefied natural gas during transportation on a ship.
