The present invention relates to a liquefied natural gas carrier and, more specifically, relates to a liquefied natural gas carrier which generates thrust by supplying boil off gas from liquefied natural gas which is being transferred to a fuel cell and rotating a motor with an electric power of the fuel cell from vaporized gas. According to an embodiment of the present invention, the liquefied natural gas carrier comprises: a valve control unit controlling at least one among nature vaporized gas and liquefied natural gas to be discharged in accordance with an amount of the nature vaporized gas contained in a gas tank wherein the liquefied natural gas is accommodated; and a fuel cell producing electric power by using the vaporized gas supplied from the gas tank.
본 발명은 액화천연가스 운반선에 관한 것으로서, 운반 중인 액화천연가스에서 발생된 기화 가스(Boil Off Gas)를 연료 전지에 공급하고, 기화 가스가 이용되어 생성된 연료 전지의 전기력으로 모터를 회전시킴으로써 추진력을 발생시키는 액화천연가스 운반선에 관한 것이다. 본 발명의 실시예에 따른 액화천연가스 운반선은 액화천연가스를 수용하는 가스 탱크에 포함되어 있는 자연 기화 가스의 양에 따라 상기 자연 기화 가스 및 상기 액화천연가스 중 적어도 하나가 배출되도록 제어하는 밸브 제어부, 및 상기 가스 탱크로부터 공급된 기화 가스를 이용하여 전력을 생산하는 연료 전지를 포함한다.
