Disclosed is a gas purging system for a ship. The gas purging system for a vessel according to the present invention comprises: a high-pressure gas injection engine driven by receiving liquefied gas as fuel; a low-pressure gas injection engine driven by receiving liquefied gas of lower pressure compared to the high-pressure gas injection engine as fuel; a first fuel supply line which compresses and vaporizes liquefied gas stored in a liquefied gas storage tank and supplies the gas to the high-pressure gas injection engine; a second fuel supply line which compresses and vaporizes liquefied gas stored in a liquefied gas storage tank and supplies the gas to the low-pressure gas injection engine; a first purging line that supplies inert gas to the high-pressure gas injection engine to purge the interior of the high-pressure gas injection engine and the first fuel supply line; and a second purging line which supplies inert gas to the low-pressure gas injection engine to purge the interior of the low-pressure gas injection engine and the second fuel supply line, for the purpose of purging. The inert gas supplied through the first and second purging lines is directly supplied to the high-pressure gas injection engine and the low-pressure gas injection engine, respectively. The purging of the high-pressure gas injection engine is performed from the interior of the high-pressure gas injection engine in the direction of the first fuel supply line. The purging of the low-pressure gas injection engine is performed from the interior of the low-pressure gas injection engine in the direction of the first fuel supply line. Therefore, the present invention can maximize safety by reducing the gas line arranged in the engine room.

    선박의 가스 퍼징시스템이 개시된다. 본 발명에 따른 선박의 가스 퍼징시스템은, 액화가스를 연료로 공급받아 구동되는 고압가스 분사엔진; 고압가스 분사엔진 대비 저압의 액화가스를 연료로 공급받아 구동되는 저압가스 분사엔진; 액화가스 저장탱크에 저장된 액화가스를 압축 및 기화시켜 고압가스 분사엔진으로 공급하는 제1 연료공급라인; 액화가스 저장탱크에 저장된 액화가스를 압축 및 기화시켜 저압가스 분사엔진으로 공급하는 제2 연료공급라인; 고압가스 분사엔진의 내부 및 제1 연료공급라인을 퍼징시키기 위한 목적으로 고압가스 분사엔진으로 불활성가스를 공급하는 제1 퍼징라인; 및 저압가스 분사엔진의 내부 및 제2 연료공급라인을 퍼징시키기 위한 목적으로 저압가스 분사엔진으로 불활성가스를 공급하는 제2 퍼징라인을 포함하고, 제1 퍼징라인 및 제2 퍼징라인으로 공급되는 불활성가스는 고압가스 분사엔진과 저압가스 분사엔진에 각각 직접 공급되며, 고압가스 분사엔진의 퍼징은 고압가스 분사엔진의 내부로부터 제1 연료공급라인 측 방향으로 이루어지고, 저압가스 분사엔진의 퍼징은 저압가스 분사엔진의 내부로부터 제1 연료공급라인 측 방향으로 이루어지는 것을 특징으로 한다.
