A liquefied gas fuel supply system for a ship is disclosed. According to the present invention, the liquefied gas fuel supply system of a ship comprises: an engine room in which a propulsion engine of a ship receiving liquefied gas as fuel is disposed; a cargo compressor room disposed on an upper portion of a deck and having a fuel supply unit disposed to supply liquefied gas in accordance with a fuel supply condition required by the propulsion engine; a gas valve train (GVT) room disposed adjacent to the engine room on the upper portion of the deck and having a GVT including a plurality of valves to control fuel supply from the fuel supply unit to the propulsion engine; and a vent line connected from the GVT. When gas fuel operation of the propulsion engine is stopped, gas fuel supply is blocked by the GVT, and gas fuel remaining in a fuel supply pipe between the GVT and the propulsion engine is discharged to the vent line.

    선박의 액화가스 연료공급시스템이 개시된다. 본 발명의 선박의 액화가스 연료공급시스템은, 액화가스를 연료로 공급받는 선박의 추진엔진이 배치되는 엔진룸; 데크 상부에 마련되며 상기 추진엔진에서 요구하는 연료공급조건에 따라 액화가스를 공급하기 위한 연료공급부가 배치되는 카고컴프레서룸; 상기 데크 상부에서 상기 엔진룸에 인접하여 마련되며 상기 연료공급부로부터 상기 추진엔진으로 연료 공급을 제어하기 위한 복수의 밸브들을 포함하는 GVT(Gas Valve Train)가 배치되는 GVT룸; 및 상기 GVT로부터 연결되는 벤트라인:을 포함하되, 상기 추진엔진의 가스연료 운전 중단(Gas Stop) 시, 상기 GVT에 의해 가스연료 공급을 차단하고 상기 GVT와 추진엔진 사이의 연료공급배관에 잔존하는 가스연료는 상기 벤트라인으로 배출되는 것을 특징으로 한다.
