액화가스추진 선박의 연료공급시스템 및 방법이 개시된다. 본 발명의 액화가스추진 선박의 연료공급시스템은, 선박에 마련되어 상기 선박의 엔진으로 공급될 액화가스를 저장하는 카고 탱크; 상기 카고 탱크와 상기 엔진 사이에 마련되어 상기 엔진으로 상기 액화가스를 연료로 공급하는 제1 및 제2 저장탱크; 상기 엔진으로부터 제1 저장탱크로 연결되는 제1 리턴라인; 및 상기 제1 리턴라인에서 분기되어 상기 제2 저장탱크로 연결되는 제2 리턴라인; 을 포함하되, 상기 제1 및 제2 저장탱크 중 어느 하나로부터 상기 엔진으로 상기 액화가스가 공급되면, 상기 엔진에 공급된 상기 액화가스는 상기 제1 또는 제2 리턴라인을 통해 상기 제1 및 제2 저장탱크 중 다른 하나로 공급될 수 있는 것을 특징으로 한다.

    Disclosed are a fuel supply system for a liquefied gas propulsion vessel and a method thereof. The fuel supply system for a liquefied gas propulsion vessel of the present invention comprises: a cargo tank which is disposed at a vessel to store a liquefied gas to be supplied to an engine of the vessel; first and second storage tanks which are disposed between the cargo tank and the engine to supply the liquefied gas to the engine as fuel; a first return line connected from the engine to the first storage tank; and a second return line which is branched from the first return line to be connected to the second storage tank. When the liquefied gas is supplied from one of the first and second storage tanks to the engine, the liquefied gas supplied to the engine can be supplied to the other one of the first and second storage tanks by means of the first return line or the second return line. Therefore, installation costs are reduced, and LPG can be stably supplied to the engine.
