The present invention relates to a liquefied gas fuel supply system for a vessel using liquefied gas as fuel for an engine and, more specifically, to a fuel supply system for a liquefied gas fuel vessel, capable of overcoming difficulty in driving caused by a pressure change in fuel. According to the present invention, in regard to the fuel supply system for a liquefied gas fuel vessel using liquefied gas as fuel for an engine, the engine, which is a high-pressure gas injection engine, includes: a high-pressure pump compressing the liquefied gas with high pressure required for the engine; a high-pressure evaporator evaporating the high-pressure liquefied gas compressed by the high-pressure pump; and a pressure control means installed between the engine and the high-pressure evaporator, and provided to control piping pressure between the engine and the high-pressure evaporator. The pressure control means includes a buffer tank for temporarily storing the high-pressure fuel gas evaporated by the high-pressure evaporator. Thus, the high-pressure fuel gas discharged from the buffer tank is supplied as fuel for the engine to keep pressure between the high-pressure evaporator and the engine constant.

    본 발명은 액화가스를 엔진의 연료로 사용하는 선박의 액화가스 연료 공급 시스템에 있어서, 연료의 압력 변동에 의한 운전의 어려움을 극복할 수 있는 액화가스 연료 선박의 연료 공급 시스템에 관한 것이다. 본 발명의 액화가스 연료 선박의 연료 공급 시스템은, 액화가스를 엔진의 연료로 사용하는 액화가스 연료 선박의 연료 공급 시스템에 있어서, 상기 엔진은 고압가스 분사엔진이고, 상기 액화가스를 상기 엔진에서 요구하는 고압으로 압축하는 고압펌프; 상기 고압펌프에 의해 압축된 고압 액화가스를 기화시키는 고압기화기; 및 상기 고압기화기와 엔진 사이에 설치되며, 상기 고압기화기와 엔진 사이의 배관 압력을 조절하기 위한 압력 조절 수단;을 포함하며, 상기 압력 조절 수단은, 상기 고압기화기에서 기화된 고압 연료가스를 임시저장하는 버퍼탱크;를 포함하여, 상기 버퍼탱크로부터 배출된 고압 연료가스가 상기 엔진의 연료로 공급되어, 상기 고압기화기와 엔진 사이의 압력을 일정하게 유지시키는 것을 특징으로 한다.
