The present invention relates to a ship having an engine using a fuel gas. The present invention provides a gas purging system for a ship, comprising: a fuel supply line for supplying a fuel gas to an engine; a gas valve unit installed on the fuel supply line to control the pressure of the fuel gas; and a purging line for supplying nitrogen gas to the engine for the purpose of purging the interior of the engine and the interior of the fuel supply line, wherein the nitrogen gas supplied from the purging line is directly supplied to the engine and is discharged to the outside air through the gas valve unit after purging the interior of the engine and the fuel supply line, thereby capable of ensuring safety from the risk of explosion.
본 발명은 연료가스를 사용하는 엔진을 구비하는 선박에 있어서, 엔진으로 연료가스를 공급하는 연료공급라인; 연료공급라인 상에 설치되어 연료가스의 압력을 제어하는 가스밸브유닛(Gas Valve Unit); 엔진의 내부 및 연료공급라인의 내부를 퍼징시키기 위한 목적으로 엔진으로 질소가스를 공급하는 퍼징라인을 포함하고, 퍼징라인으로부터 공급되는 질소가스는, 엔진으로 직접 공급되어 엔진의 내부 및 연료공급라인을 퍼징시킨 후, 가스밸브유닛을 통해 외기로 배출되는 것을 특징으로 하는, 선박의 가스 퍼징시스템을 제공한다.
