SYSTEM AND METHOD FOR SUPPLYING FUEL GAS OF LNG CARRIER

摘要

A system and a method for supplying fuel gas of an LNG(Liquefied Natural Gas) carrier are provided to save power consumption with a simple construction in supplying the fuel gas to the LNG carrier with a high pressure gas ejection engine. A system for supplying fuel gas of an LNG(Liquefied Natural Gas) carrier includes an LNG supplying line(L1), an evaporation gas supplying line(L2), a condenser(3), and a fuel gas supplying line(L3). The LNG supplying line extracts the LNG from a bottom of an LNG storage tank(1). The evaporation gas supplying line extracts the evaporation gas from a top of the LNG storage tank. The condenser generates the LNG condensed by mixing/liquefying the LNG extracted from the bottom of the LNG storage tank and the evaporation gas extracted from the top of the LNG storage tank by being connected to the LNG supplying line and the evaporation gas supplying line. The fuel gas supplying line supplies the condensed LNG to a high pressure gas ejection engine(10) by being connected to the high pressure gas ejection engine from the condenser.
