액화가스 운반선은, 액화가스를 저장하기 위한 탱크와; 탱크 내에서 액화가스가 기화하여 발생한 기화가스가 연료로서 공급되는 가스연료기관과; 탱크로부터 가스연료기관에 기화가스를 공급하기 위한 가스공급라인과; 가스공급라인에 배치되고 기화가스를 가스연료기관으로 압송하는 가스 압축기와; 가스공급라인으로부터, 가스연료기관에 공급되지 않은 잉여 가스를 탱크로 되돌려보내기 위한 가스 리턴 라인과; 가스 리턴 라인을 개폐하는 가스 리턴 밸브; 를 구비한다. 가스 리턴 라인은, 탱크의 높낮이 방향의 중앙 영역 내에 위치하여, 잉여 가스를 탱크에 분출하는 잉여 가스 분출부를 가진다.
A liquefied gas carrier includes: a tank storing a liquefied gas; a gas fueled engine, to which a boil off gas is supplied as a fuel, the boil off gas being generated when the liquefied gas vaporizes in the tank; a gas supply line, through which the boil off gas is supplied from the tank to the gas fueled engine; a gas compressor disposed on the gas supply line and configured to pressure-feed the boil off gas to the gas fueled engine; a gas return line, through which an excess gas that has not been supplied through the gas supply line to the gas fueled engine is returned to the tank; and a gas return valve configured to open and close the gas return line. The gas return line includes an excess gas spouting portion positioned in a central region of the tank in a height direction and configured to spout the excess gas to the tank.
