The present invention relates to a container ship of a twin island structure, wherein an engine casing is arranged at the stern unit over the upper deck, and a cabin is arranged at the front side of the engine casing at a location spaced apart therefrom. In particular, provided is a fuel gas supply system of a container ship, which comprises: an LNG fuel tank which is arranged within a hold formed at the lower side of a cabin; an engine which is provided in an engine room divided on the inside of the hull at the lower side of the engine casing, and is operated after receiving the LNG stored in the LNG fuel tank or the BOG generated within the LNG fuel tank as fuel; and a fuel supply line which supplies fuel gas from the LNG fuel tank to the engine. Here, the fuel supply line is extended to the stern side towards the engine room at the upper portion of the upper deck after penetrating the upper deck in the upper direction from the LNG fuel tank, and is arranged in a shape of being protected by an accommodating unit formed at the lower side portion of a hatch coaming installed at the side portion of the hull. Therefore, the present invention can be immediately applied to a real ship.
본 발명은 어퍼데크 상에서 선미부에 엔진케이싱이 배치되고 엔진케이싱의 전방에 이격되는 위치에 선실이 배치되는 트윈 아일랜드 구조의 컨테이너선에 있어서, 선실의 하측에 형성되는 홀드 내에 배치되는 LNG 연료탱크; 엔진케이싱의 하측 선체 내부에 구획되는 엔진룸 내에 구비되며, LNG 연료탱크에 저장된 LNG 또는 LNG 연료탱크 내에서 발생하는 BOG를 연료로서 공급받아 구동되는 엔진; LNG 연료탱크로부터 엔진으로 연료가스를 공급하는 연료공급라인을 포함하고, 상기 연료공급라인은 LNG 연료탱크로부터 어퍼데크를 상방으로 관통하여 어퍼데크의 상부에서 엔진룸을 향하여 선미 측으로 연장되되, 선체의 측부에 설치되는 해치코밍의 하측부에 형성되는 수용부에 의해 보호되는 형태로 배치되는 것을 특징으로 하는, 컨테이너선의 연료가스 공급시스템을 제공한다.
