The present invention relates to an LNG fuel-propelled ship, wherein an LNG fuel tank is installed by securing a proper space on the upper part of an engine room upper deck without being installed in a cargo hold to remove a decrease in the amount of cargo and maintain horizontal strength and stability of the ship. According to the present invention, an integrated structure having an engine casing and a deck housing integrally formed therein is installed on one side of the upper part of the engine room upper deck, and the LNG fuel tank is installed by securing the proper space on the upper part of the engine room upper deck, and thus interference with fittings, such as a mooring device, is able to be effectively avoided. Moreover, the LNG fuel tank is installed on the upper part of the engine room upper deck, and thus a bunkering line to the engine line is able to be reduced, and pipeline and a vent riser are able to be optimally disposed. Moreover, explosion risk of the LNG fuel tank is blocked by a shelter structure for surrounding the outer circumferential surface of the LNG fuel tank and thus safety is able to be enhanced.

    본 발명은 LNG 연료 추진선박에 관한 것으로, LNG 연료 탱크가 화물창에 설치되지 않고 엔진 룸 어퍼 데크 상부에 적절한 공간을 확보하여 설치되므로 화물량의 감소가 없으며, 선박의 종 방향 강도와 안정성(stability)을 유지할 수 있는 효과가 있다. 또한, 엔진 룸 어퍼 데크의 상부 일측에 엔진 케이싱과 데크 하우스가 일체로 구성된 일체형 구조물이 설치되고, LNG 연료 탱크가 엔진 룸 어퍼 데크 상부에 적절한 공간을 확보하여 설치되므로, 무어링 장치 등 의장품과의 간섭을 효과적으로 피할 수 있다. 또한, 엔진룸 어퍼 데크의 상부에 LNG 연료 탱크가 설치되므로 엔진룸으로의 벙커링 라인을 단축하고 배관 및 벤트 라이저를 최적으로 배치할 수 있다. 또한, LNG 연료 탱크의 외주 면을 감싸는 쉘터 구조에 의해서 LNG 연료 탱크의 폭발 위험성을 차단하여 안전성을 높일 수 있다.
