The present invention relates to a liquefied gas storage tank, a gas fuel supply system, and a ship. The liquefied gas storage tank, which is stored liquefied gas therein and coexists with boil off gas in which the liquefied gas is vaporized, includes a stratification identification unit measuring or estimating temperature of a liquid surface which is a boundary surface of the liquefied gas and the boil off gas and determining the presence or absence of generation of a stratification phenomenon that temperature of the liquefied gas in a section from the liquid surface to a certain point downwards is increased toward the liquid surface so that the temperature of the liquefied gas in the liquid surface is higher than the temperature of the liquefied gas at an inner floor as the temperature of the liquefied gas and the boil off gas is differently heated by external heat penetration.

    본 발명은 액화가스 저장탱크, 가스연료 공급 시스템 및 선박에 관한 것으로서, 내부에 액화가스를 저장하며, 액화가스가 증발한 증발가스가 공존하는 액화가스 저장탱크로서, 액화가스와 증발가스의 경계면인 액면의 온도를 측정 또는 추정하여, 외부 열침투로 인하여 액화가스와 증발가스의 온도가 상이하게 가열됨에 따라 액면으로부터 하방으로 일정 지점까지의 구간에서 액화가스의 온도가 상기 액면으로 갈수록 상승하여 상기 액면에서의 액화가스 온도가 상기 내부 바닥에서의 액화가스 온도보다 높게 나타나는 성층화 현상의 발생 여부를 판단하는 성층화 파악부가 마련되는 것을 특징으로 한다.
