PURPOSE : A Re-liquefaction apparatus and a fuel supply system of a marine structure with a high-pressure natural gas injection engine are provided to prevent the generation of flash gas when LBOG(Liquefied Boil-Off Gas) returns to an LNG storage tank.CONSTITUTION : A fuel supply system for a high-pressure natural gas injection engine comprises a LBOG return line(L41) and a pressure control valve(145). A fuel supply line(L13) supplies fuel to the high-pressure natural gas injection engine from a re-liquefaction apparatus(120) through a high pressure pump. The LBOG return line branches from the middle of the fuel supply line, and returns the re-liquefied LBOG to a storage tank(110). The pressure control valve is installed in the LBOG return line, and maintains the pressure of the fuel supply line.COPYRIGHT KIPO 2013
