본 발명은 선미 방향으로 후방 측 상부에 형성되는 리퀴드 돔을 포함하는 LNG 저장탱크의 단열시스템에 있어서, 금속 멤브레인으로 이루어져 LNG 저장탱크에 저장되는 LNG를 밀봉하는 밀봉벽; 및 LNG의 단열을 위해 밀봉벽의 외측에 설치되는 단열벽을 포함하고, 단열벽은, LNG 저장탱크의 내벽 가장자리 둘레 및 리퀴드 돔의 주위를 따라 배치되는 단열박스; 및 LNG 저장탱크의 내벽 상에서 단열박스가 배치되는 구역 이외의 구역에 배치되는 단열패널을 포함하되, 리퀴드 돔과 LNG 저장탱크의 후방벽 사이에 형성되는 단열벽은, 단열패널의 배치 없이 단열박스의 조합으로만 이루어지는 것을 특징으로 하는, LNG 저장탱크의 단열시스템을 제공한다.

    An objective of the present invention is to improve productivity when constructing a liquefied natural gas (LNG) storage tank. An insulation system of an LNG storage tank including a liquid dome formed on in upper portion of the rear side toward the stern comprises: a sealing wall consisting of a metal membrane to seal LNG stored in the LNG storage tank; and an insulation wall installed on the outside of the sealing wall for insulation of the LNG. The insulation wall includes: insulation boxes arranged around the liquid dome and the edge of the inner wall of the LNG storage tank; and insulation panels arranged on an area other than the area on which the insulation boxes are arranged on the inner wall of the LNG storage tank. The insulation wall formed between the liquid dome and the rear wall of the LNG storage tank is formed by only a combination of the insulation boxes without arranging the insulation panels.
