Disclosed is a fuel gas supply system of a ship including a dual fuel engine. The fuel gas supply system of a ship including a dual fuel engine according to the present invention comprises: an engine room divided inside the hull of a stern part; a main engine arranged in the engine room and providing propelling power of the ship; a power generation engine arranged in the engine room and producing electric power needed in the ship; a liquefied gas fuel tank storing liquefied gas, which is supplied as the fuel of the main engine and the power generation engine; a fuel supply part pressurizing the liquefied gas stored in the liquefied gas fuel tank or evaporative gas generated inside the liquefied gas fuel tank depending on the requirements of the main engine or the power generation engine; a second fuel supply line supplying fuel gas from the fuel supply part to the power generation engine; and a gas valve unit installed on the second fuel supply line to control the pressure of the fuel gas supplied to the power generation engine, wherein the gas valve unit is configured on a sunken deck existing at the stern side of the ship and is arranged in a gas valve unit room which is arranged to be adjacent to the rear of the engine room. Therefore, provided is a fuel gas supply system of a ship which can satisfy requirements while ensuring economic efficiency and safety.

    이중연료 엔진을 구비하는 선박의 연료가스 공급시스템이 개시된다. 본 발명에 따른 이중연료 엔진을 구비하는 선박의 연료가스 공급시스템은, 선미부의 선체 내부에 구획되는 엔진룸; 엔진룸 내부에 배치되며 선박의 추진 동력을 제공하는 메인엔진; 엔진룸 내부에 배치되며 선내에 필요한 전력을 생산하는 발전엔진; 메인엔진과 발전기엔진의 연료로서 공급되는 액화가스가 저장되는 액화가스 연료탱크; 액화가스 연료탱크에 저장된 액화가스 또는 액화가스 연료탱크 내에서 발생하는 증발가스를 메인엔진 또는 발전기 엔진에서 요구하는 조건에 맞추어 가압하는 연료공급부; 연료공급부로부터 발전엔진으로 연료가스를 공급하는 제2 연료공급라인; 및 제2 연료공급라인 상에 설치되어 발전엔진으로 공급되는 연료가스의 압력을 제어하는 가스밸브유닛을 포함하고, 가스밸브유닛은 선박의 선미 측에 존재하는 저선미루갑판 상에 구성되되 엔진룸의 후방에 바로 인접하게 배치되는 가스밸브유닛룸 내에 배치되는 것을 특징으로 한다.
