An objective of the present invention is to provide a membrane-type liquefied gas insulation system capable of securing better performance than a conventional technique in the aspect of both insulation and airtightness. The membrane-type liquefied gas insulation system of a double metal barrier structure has a double sealing structure in which a secondary insulation layer, a secondary membrane, a primary insulation layer, and a primary membrane are sequentially stacked from an inner wall of a storage container toward the inside of the storage container and comprises: a plurality of secondary insulation panels continuously arranged on the inner wall of the storage container to make up the secondary insulation layer; a plurality of primary insulation panels continuously arranged on the secondary membrane to make up the primary insulation layer; and an insulation layer fixing device fixing the primary insulation panels on an upper portion of the secondary insulation layer. The insulation layer fixing device includes: a fixing plate installed in the middle of an upper portion of the secondary insulation panels; and four studs provided on the fixing plate to protrude upwards. The corner portions of the primary insulation panels are individually fixed by one among the four studs.

    저장용기의 내벽면으로부터 저장용기의 내측 방향으로 2차 단열층, 2차 멤브레인, 1차 단열층 및 1차 멤브레인이 순차 적층되는 이중 밀봉 구조를 가지는 멤브레인형 액화가스 단열시스템에 있어서, 저장용기의 내벽면 상에 다수개가 연속적으로 배치되어 2차 단열층을 구성하는 2차 단열패널; 2차 멤브레인 상에 다수개가 연속적으로 배치되어 1차 단열층을 구성하는 1차 단열패널; 및 2차 단열층의 상부에 1차 단열패널을 고정시키는 단열층 고정장치를 포함하고, 상기 단열층 고정장치는, 2차 단열패널의 상부 중앙에 설치되는 고정 플레이트; 및 고정 플레이트 상에 상방으로 돌출되도록 구비되는 4개의 스터드를 포함하며, 1차 단열패널은 모퉁이 부위가 4개의 스터드 중 어느 하나에 의하여 개별적으로 고정되는 것을 특징으로 하는, 이중 금속 방벽 구조의 멤브레인형 액화가스 단열시스템이 개시된다.
