RELIQUEFACTION GAS STORAGE SYSTEM FOR RELIQUEFACTION SYSTEM OF LNG CARRIER

A reliquefaction gas storage system for a reliquefaction system of an LNG(Liquefied Natural Gas) carrier is provided to maximize storing of reliquefied natural gas and management efficiency of the reliquefaction system and to prevent gas of storage tanks from flowing over by automatically storing the reliquefied natural gas correspondently to capacity of plural storage tanks. A reliquefaction system of an LNG carrier is composed of a reliquefaction compressor compressing the evaporated gas generated from an LNG storage tank(50) and then supplying the compressed gas to a reliquefaction device(A); a stripping/spray main header supplying the reliquefied gas to plural storage tanks; a supply pipe(2) connected from the stripping/spray main header to each storage tank by installing plural branch pipes; plural first valves installed at the supply pipe to control the supply of the reliquefied natural gas toward each storage tank; plural second valves installed at the branch pipes to supply or cut off the reliquefied natural gas passing through the first valves, to/from each storage tank; and a control unit(5) for detecting the present available fill-up amount of plural storage tanks and controlling the first and second valves to supply the reliquefied natural gas to the storage tanks in order.
