The present invention relates to a liquefied gas storage tank, a gas fuel supply system, and a ship which can guarantee transport stability of liquefied gas. The gas fuel supply system is arranged on a ship other than a liquefied gas carrier, which loads liquefied gas therein as fuel for propulsion. The gas fuel supply system comprises: a pressurizing liquefied gas storage tank storing liquefied gas at a high pressure therein and allowing evaporation gas created by evaporating the liquefied gas to coexist; a stratification suppressing unit allowing the liquefied gas or the evaporation gas stored in the liquefied gas storage tank to flow to drop the temperature of the liquefied gas at a liquid surface which is the boundary surface between the liquefied gas and the evaporation gas in a direction of becoming closer to the temperature of the liquefied gas at the bottom in the liquefied gas storage tank; and a gas fuel processing unit to supply the gas of the liquefied gas storage tank to a user entity. The gas fuel processing unit supplies the liquefied gas as main fuel of the user entity or does not supply the evaporation gas to the user entity while sailing as the stratification suppressing unit suppresses a stratification phenomenon to delay a pressure increase of the liquefied gas storage tank.

    본 발명은 액화가스 저장탱크, 가스연료 공급 시스템 및 선박에 관한 것으로서, 액화가스를 추진용 연료로서 적재하는, 액화가스 운반선 외의 선박에 마련되는 가스연료 공급 시스템으로서, 내부에 액화가스를 고압으로 저장하며 액화가스가 증발한 증발가스가 공존하는 가압형의 액화가스 저장탱크; 상기 액화가스 저장탱크의 내부에 저장된 액화가스 또는 증발가스를 유동하여 액화가스와 증발가스의 경계면인 액면에서의 액화가스 온도를 상기 액화가스 저장탱크의 내부 바닥에서의 액화가스 온도에 가까워지는 방향으로 떨어뜨리는 성층화 억제부; 및 상기 액화가스 저장탱크의 가스를 수요처로 공급하는 가스연료 처리부를 포함하며, 상기 가스연료 처리부는, 상기 성층화 억제부가 성층화 현상을 억제하여 상기 액화가스 저장탱크의 압력 상승을 지연시킴에 따라, 운항 중 액화가스를 상기 수요처의 메인연료로 공급하거나 증발가스를 상기 수요처에 공급하지 않는 것을 특징으로 한다.
