Liquefied Petroleum Gas Fueled Ship and Fuel Supply Method of LPG Fueled Ship

摘要

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.
