According to the present invention, a liquefied gas storage tank comprises: a primary barrier forming an enclosed space for storing liquefied gas; a secondary barrier located a certain distance away from the primary barrier and enclosing the primary barrier; a plurality of supports located between the primary barrier and the secondary barrier to maintain a certain distance between the primary barrier and the secondary barrier, and supporting the primary barrier with respect to the secondary barrier; and an insulating part which is in contact with the secondary barrier and surrounds the secondary barrier. The present invention may realize a liquefied gas storage tank lowering the manufacturing cost and maximizing the storage capacity since it is easy to inspect the barriers because the primary and secondary barriers are exposed to a space connected to the outside, and since it is possible to apply general members to the barrier by avoiding the application of structural members with large cross sections or cryogenic materials.

    본 발명에 따른 액화가스 저장탱크는, 액화가스가 저장되기 위한 밀폐공간을 형성하는 1차 방벽; 1차 방벽에서 외측으로 일정거리 이격되어 위치하며 1차 방벽을 둘러싸는 2차 방벽; 1차 방벽과 2차 방벽 사이에 위치하여 1차 방벽과 2차 방벽의 일정거리를 유지하되, 2차 방벽에 대해 1차 방벽을 지지시키는 복수의 서포트; 및 2차 방벽에 접촉되어 2차 방벽을 둘러싸는 단열부를 포함한다. 상기와 같은 본 발명은, 1차 방벽과 2차 방벽이 외부와 연결되는 공간에 노출되어 방벽들의 검사가 용이하며, 방벽에 비싸고 단면이 큰 구조용 부재 또는 극저온 재질의 부재의 적용을 회피하여 일반적인 부재를 적용할 수 있으므로 제작단가를 낮추고 저장용량을 극대화한 액화가스 저장탱크를 구현한다.
