PURPOSE : A re-liquefying apparatus and a fuel supply system of a marine structure with a high-pressure natural gas injection engine are provided to reduce loads on the re-liquefying apparatus by re-condensing some of BOG(Boil-Off Gas).CONSTITUTION : A fuel supply system for a high-pressure natural gas injection engine comprises a BOG compression unit, a re-liquefying apparatus, a high pressure vaporizer, and a re-condenser(131). The BOG compression unit compresses the BOG generated from a storage tank(110). The re-liquefying apparatus liquefies evaporation gas compressed in the BOG compression unit. The high pressure pump compresses the BOG liquefied in the re-liquefying apparatus. The high pressure vaporizer vaporizes the LBOG compressed in the high pressure pump. The re-condenser is installed in an upper side of the high pressure pump. The re-condenser re-condenses some or the whole BOG using the LNG supplied from the storage tank.COPYRIGHT KIPO 2013
