PURPOSE: A ship is provided to save energy by preventing liquefied natural gas used to the fuel of a high pressure jetting engine from being unnecessarily overcooled. CONSTITUTION: A ship comprises a storage tank(110), an evaporative gas compression part(130), a condenser(140), a gas-liquid separator(170), a fuel supply line, a pump(180), and a vaporizer(190). The storage tank stores liquefied natural gas. The evaporative gas compression part compresses evaporative gas supplied from the storage tank. The condenser overcools the evaporative gas compressed in the evaporative gas compression part after the evaporative gas is reliquefied by heat-exchanging with refrigerant. The gas-liquid separator separates liquefied natural gas from the saturated liquefied natural gas supplied from the condenser. The fuel supply line supplies the liquefied natural gas separated from the gas-liquid separator to a high pressure gas jetting engine. The pump compresses the separated liquefied natural gas. The vaporizer vaporizes the liquefied natural gas compressed in the pump. [Reference numerals] (200) High pressure jetting engine |
