PURPOSE: A LNG(Liquefied Natural Gas) carrier is provided to increase efficiency of a reliquefaction process of a carrier by reliquefying after compressing evaporative gas generated in a LNG storage tank with different pressures. CONSTITUTION: A LNG carrier comprises a hull, a storage tank(110), a compression part, a condenser(140), a vapor-liquid separator(160), a pump, a vaporizer, a heating part, and an engine. The storage tank is arranged in the hull and stores the LNG. The compression part compresses evaporative gas generated in the storage tank with different pressures. The condenser condenses the evaporative gas compressed in the compression part. The vapor-liquid separator separates the condensed LNG. The pump is arranged between the condenser and the vapor-liquid separator and is installed in a passage through which the evaporative gas compressed by lower pressure flows. The vaporizer vaporizes the LNG separated in the vapor-liquid separator. The heating part is arranged between the vaporizer and the vapor-liquid separator and heats the LNG supplied to the vaporizer. |
