PURPOSE: A ship is provided to excessively cool liquefied natural gas to be used as the fuel of a high pressure gas spraying engine and to reduce the heat quantity to be supplied to an evaporator by arranging a pre-heater in the front end of the evaporator. CONSTITUTION: A ship(100) comprises a storage tank(110), an evaporating gas compression part(130), a condenser(140), a fuel feeding line(102), a pump(180), and an evaporator(190). The storage tank stores liquefied natural gas. The evaporating gas compression part compresses evaporative gas fed from the storage tank. The condenser excessively cool after being reliquefied by heat-exchanging the evaporative gas compressed in the evaporating gas compression part and refrigerant. The fuel feeding line feeds the liquefied natural gas of a saturation state passing through the condenser to a high pressure gas spraying engine(200). The pump is provided on the fuel feeding line and compresses the liquefied natural gas of the saturation state. The evaporator evaporates the liquefied natural gas compressed in the pump.
