The present invention relates to a liquefied natural gas (LNG) storage tank and an insulation panel securing device thereof, which is configured to make a first insulation panel to be slidable in the horizontal direction, so that enables to reduce thermal stress. According to an embodiment of the present invention, in regard to a storage tank storing LNG, a storage tank comprises: a first sealing panel which is in contact with the LNG stored in the storage tank and seals the LNG liquid-tightly; a first insulation panel which is positioned below the first sealing panel and insulates the LNG; a second insulation panel which is installed at an inner wall of the storage tank and insulates the LNG; and an insulation panel securing device which secures the first insulation panel to the second insulation panel, wherein the first insulation panel is configured to be slidable in the horizontal direction.

    본 발명은 1차 단열벽이 수평 방향으로 슬라이딩할 수 있도록 구성되어 열응력을 감소시킬 수 있는 액화천연가스 저장탱크 및 액화천연가스 저장 탱크의 단열벽 고정장치에 관한 것이다. 본 발명의 일 실시예에 따르면, 액화천연가스를 저장하는 저장 탱크에 있어서, 상기 저장탱크에 저장된 액화천연가스와 접하면서 상기 액화천연가스를 액밀하는 1차 밀봉벽; 상기 1차 밀봉벽의 아래에 위치하면서 상기 액화천연가스를 단열시키는 1차 단열벽; 상기 저장탱크의 내부벽에 설치되어 상기 액화천연가스를 단열시키는 2차 단열벽; 및 상기 1차 단열벽이 수평방향으로 슬라이딩할 수 있는 구조로 상기 1차 단열벽을 상기 2차 단열벽에 고정시키는 단열벽 고정장치를 포함하는 저장탱크가 제공된다.
