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 stably maintain the subcooling state of LBOG(Liquefied Boil-Off Gas).CONSTITUTION : A pre-cooling unit of a fuel supply system for a high-pressure natural gas injection engine pre-cools LBOG supplied to a re-liquefying apparatus when a fuel supply to the high-pressure natural gas injection engine is stopped. The pre-cooling unit comprises a LNG(Liquefied Natural Gas) branch line and a LNG(Liquefied Natural Gas) joining line. The LNG branch line is connected to a fuel supply line(L3) in a lower part of a high pressure pump(33), and supplies LNG supplied from a storage tank. The LNG joining line is connected to an evaporation gas supply line(L2) of a BOG compression unit(13), and branches from the fuel supply line.COPYRIGHT KIPO 2013
