Abstract: PURPOSE: A method and system apparatus for reliquefying an evaporation gas of an LNG transporting vessel is provided to liquefy an evaporation gas generated as being evaporated by an external heat in a storage tank of the LNG transporting vessel. CONSTITUTION: The apparatus comprises: a spray chiller(20) which is connected to a storage tank(10) for firstly chilling the evaporation gas; a reliquefaction compressor(30) which is connected to the spray chiller(20) for pressurizing the firstly chilled evaporation gas; an evaporation gas condenser(40) which is connected to the reliquefaction compressor(30) for liquefying the pressurized evaporation gas; a second valve(110) which is connected to the evaporation gas condenser(40) for carrying parts of the liquefied evaporation gas to the spray chiller(20); a re-mixer(120) which mixes the liquefied evaporation gas with LNG of ultra low temperature stored in the storage tank(10); a reliquefied liquid recovering line(130) which is connected to the re-mixer(120) for storing the liquefied evaporation gas in the storage tank(10); and a strip spray pump(140) which carries the LNG mounted and stored at a lower part of the storage tank(10) to the re-mixer(120) through a third valve(150).
