The present invention relates to a liquefied natural gas (LNG) storage tank having a processed groove which is arranged with a corrugated part of a secondary sealing wall on a secondary insulation wall, and an insulation wall of the LNG storage tank. According to an embodiment of the present invention, in a storage tank for storing the LNG, the LNG storage tank includes: a primary sealing wall which liquid-tightens the LNG in contact with the LNG stored in the storage tank; a primary insulation wall which insulates the LNG as being located under the first sealing wall; a secondary insulation wall which insulates the LNG by being installed on an inner wall of the storage tank; and a secondary sealing wall which liquid-tightens of the LNG in case the primary sealing wall leaks, by being located between the primary insulation wall and the secondary insulation wall. The secondary insulation wall includes a plurality of secondary insulation wall panels, and a groove is processed on an upper part of each of the secondary insulation wall panels. A corrugated part is formed on the secondary sealing wall, and the secondary sealing wall is arranged on the secondary insulation wall so that the corrugated part is arranged in the groove or the gap among the secondary insulation wall panels.

    본 발명은 2차 단열벽에 2차 밀봉벽의 주름부가 배치되는 홈이 가공되어 있는 액화천연가스 저장탱크 및 액화천연가스 저장 탱크의 단열벽에 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 단열벽과 상기 2차 단열벽 사이에 위치하여 상기 1차 밀봉벽이 새는 경우 상기 액화천연가스를 액밀하는 2차 밀봉벽을 포함하고, 상기 2차 단열벽은 복수의 2차 단열벽 패널들을 포함하고, 상기 복수의 2차 단열벽 패널들 각각의 상부에는 홈이 가공되어 있고, 상기 2차 밀봉벽에는 주름부가 형성되어 있고, 상기 2차 밀봉벽은 상기 주름부가 상기 복수의 2차 단열벽 패널들 사이의 갭 및 상기 홈에 배치될 수 있도록 상기 2차 단열벽 위에 위치하는, 저장탱크가 제공된다.
