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 liquefied gas storage tank stores liquefied gas therein and allows evaporation gas created by evaporating the liquefied gas to coexist. The liquefied gas storage tank includes 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 in case of a stratification phenomenon where the temperature of the liquefied becomes higher towards the liquid surface in a section from the liquid surface to a prescribed downward point as the temperatures of the liquefied gas and the evaporation gas are differently heated to indicate that temperature of the liquefied gas at the liquid surface is higher than the temperature of the liquefied gas at the bottom in the liquefied gas storage tank.

    본 발명은 액화가스 저장탱크, 가스연료 공급 시스템 및 선박에 관한 것으로서, 내부에 액화가스를 저장하며, 액화가스가 증발한 증발가스가 공존하는 액화가스 저장탱크로서, 외부 열침투로 인하여 액화가스와 증발가스의 온도가 상이하게 가열됨에 따라, 액화가스와 증발가스의 경계면인 액면으로부터 하방으로 일정 지점까지의 구간에서 액화가스의 온도가 상기 액면으로 갈수록 상승하여 상기 액면에서의 액화가스 온도가 상기 액화가스 저장탱크의 내부 바닥에서의 액화가스 온도보다 높게 나타나는 성층화 현상이 발생하는 경우, 상기 액화가스 저장탱크의 내부에 저장된 액화가스 또는 증발가스를 유동하여 상기 액면에서의 액화가스 온도를 상기 내부 바닥에서의 액화가스 온도에 가까워지는 방향으로 떨어뜨리는 성층화 억제부가 마련되는 것을 특징으로 한다.
