액화가스추진 선박의 연료공급시스템 및 방법이 개시된다. 본 발명의 액화가스추진 선박의 연료공급시스템은, 선박에 마련되어 선내 엔진으로 공급될 액화가스를 저장하는 연료저장탱크; 상기 연료저장탱크로부터 상기 엔진으로 상기 액화가스가 공급되는 연료공급라인; 상기 엔진으로부터 상기 연료저장탱크로 연결되어 상기 액화가스를 재순환시키는 리턴라인; 상기 리턴라인에 마련되어 재순환되는 상기 액화가스를 기액분리하는 세퍼레이터; 및 상기 리턴라인으로부터 분기되어 상기 세퍼레이터에서 분리된 기체를 BOG 처리수단으로 공급하는 가스처리라인: 을 포함하며, 상기 세퍼레이터의 압력은 상기 BOG 처리수단에서의 필요 압력으로 제어되는 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 fuel storage tank which is disposed at a vessel, and stores a liquefied gas to be supplied to an engine in the vessel; a fuel supply line through which the liquefied gas is supplied from the fuel storage tank to the engine; a return line which is connected from the engine to the fuel storage tank in order to re-circulate the liquefied gas; a separator which is disposed on the return line to perform gas-liquid separation with respect to the re-circulated liquefied gas; and a gas processing line which is branched from the return line to supply the gas separated from the separator to a BOG processing means. Here, the pressure of the separator is controlled to a pressure required by the BOG processing means. Therefore, the capacity of the fuel storage tank is reduced while the re-circulated liquefied gas can be effectively processed.
