Provided are an LNG propulsion ship and a fuel supply method thereof to maintain a composition of liquefied fuel in a fuel tank in an initial condition. The LNG propulsion ship comprises: a fuel tank in which liquefied fuel is stored; a ship engine having a first engine capable of using low methane or high methane liquefied fuel as fuel and a second engine capable of using only high methane liquefied fuel as fuel; a fuel pressure pump pressurizing the liquefied fuel with pressure required for the first engine; an evaporator evaporating the pressurized liquefied fuel to be supplied to the first engine; a separator separating a heavy hydrocarbon component in the evaporated liquefied fuel to supply only the high methane liquefied fuel to the second engine; and a bypass line guiding the low methane liquefied fuel separated from the separator to the evaporator.

    연료 탱크 내 액화 연료의 조성을 초기 조건으로 유지할 수 있는 LNG 추진선박 및 LNG 추진선박의 연료공급방법이 소개된다. 이 LNG 추진선박은 액화 연료가 저장된 연료 탱크와, 저 메탄가 또는 고 메탄가의 액화 연료를 연료로 사용 가능한 제 1 엔진과 고 메탄가의 액화 연료만을 연료로 사용 가능한 제 2 엔진을 포함하는 선박 엔진과, 액화 연료를 상기 제 1 엔진이 요구하는 압력으로 가압하는 연료 압력 펌프와, 가압된 액화 연료를 기화시켜 상기 제 1 엔진에 공급하는 기화기와, 기화된 액화 연료에서 중탄화수소 성분을 분리하여 고 메탄가의 액화 연료만을 제 2 엔진에 제공하는 세퍼레이터와, 세퍼레이터에서 분리된 저 메탄가의 액화 연료를 기화기로 안내하는 바이패스 라인을 포함할 수 있다.
