Disclosed is a liquefied gas refueling ship. The liquefied gas refueling ship according to an embodiment of the present invention is a liquefied gas refueling ship supplying liquefied gas to a fuel tank of a liquefied gas-powered ship and including a first storage tank accommodating liquefied gas, a liquefied gas refueling line supplying a fuel tank with the liquefied gas accommodated in the first storage tank, and a flow management unit reducing a sloshing load applied to the first storage tank and recovering and treating evaporation gas. The flow management unit includes a second storage tank capable of accommodating the liquefied gas and the recovered evaporation gas, an evaporation gas recovery line recovering the evaporation gas generated in the fuel tank to the second storage tank, and a liquefied gas replenishment line supplying the first storage tank with the liquefied gas accommodated in the second storage tank depending on the liquefied gas carrying amount of the first storage tank.

    액화가스 급유선이 개시된다. 본 발명의 일 실시 예에 의한 액화가스 급유선은 액화가스 추진선박의 연료탱크에 액화가스를 공급하는 액화가스 급유선에 있어서, 액화가스를 수용하는 제1저장탱크, 제1저장탱크에 수용된 액화가스를 연료탱크로 공급하는 액화가스 급유라인, 제1저장탱크에 가해지는 슬로싱(Sloshing) 하중을 저감하고, 증발가스를 회수 및 처리하는 유동 관리부를 포함하고, 유동 관리부는 액화가스 및 회수된 증발가스를 수용 가능하게 마련되는 제2저장탱크와, 연료탱크에서 발생하는 증발가스를 제2저장탱크로 회수하는 증발가스 회수라인과, 제1저장탱크의 액화가스 적재량에 따라 제2저장탱크에 수용된 액화가스를 제1저장탱크로 공급하는 액화가스 보충라인을 포함하여 제공될 수 있다.
