The present invention relates to a vessel using LPG as fuel and a method of effectively supplying LPG fuel to an LPG fuel engine of the vessel using LPG as fuel. According to the present invention, the LPG fuel vessel includes: an LPG storage tank storing liquified petroleum gas (LPG); an LPG fuel engine using LPG as fuel; a reliquefication system re-liquefying evaporation gas, which is produced from the LPG storage tank, to collect the gas into the LPG storage tank; a heat exchanger exchanging heat between the LPG to be supplied to the LPG fuel engine and the evaporation gas re-liquefied in the reliquefication system to collect cold and heat from the LPG; and an after heater heating the LPG, of which cold and heat have been collected in the heat exchanger, at a temperature demanded by the LPG fuel engine.

    본 발명은 LPG를 연료로 사용하는 선박 및 LPG를 연료로 사용하는 선박의 LPG 연료 엔진으로 LPG 연료를 효과적으로 공급하는 방법에 관한 것이다. 본 발명에 따른 LPG 연료 선박은, LPG(Liquefied Petroleum Gas)를 저장하는 LPG 저장탱크; LPG를 연료로 사용하는 LPG 연료 엔진; 상기 LPG 저장탱크에서 생성된 증발가스를 재액화시켜 LPG 저장탱크로 회수하는 재액화 시스템; 상기 LPG 연료 엔진으로 공급할 LPG와 상기 재액화 시스템에서 재액화된 증발가스를 열교환시켜, 상기 LPG의 냉열을 회수하는 열교환기; 및 상기 열교환기에서 냉열이 회수된 LPG를 상기 LPG 연료 엔진에서 요구하는 온도로 가열시키는 애프터 히터;를 포함하는 것을 특징으로 한다.
