The present invention relates to an insulation system for a liquefied gas storage tank, which additionally arranges a space insulating material between an insulation box supporting an invar tube of a corner part of the liquefied gas storage tank and a sandwich-shaped insulating panel installed in a general area and properly arranges an in-plane direction of the space insulating material in a thickness direction of the insulation panel in consideration of thermal shrinkage of the insulation box and the insulation panel, thereby preventing stepped portions capable of being generated by a difference of the thermal shrinkage to efficiently prevent damage to a metal membrane without using separate materials or largely changing a structure.

    본 발명은 액화가스 저장탱크의 단열시스템에 관한 것으로, 액화가스 저장탱크의 코너 부의 인바 튜브를 지지하는 단열박스와, 일반지역에 설치되는 샌드위치 형태의 단열패널 사이에, 공간 단열재를 추가로 배치하되, 단열박스와 단열패널의 열수축량을 고려하여, 공간 단열재의 면내 방향을 단열패널의 두께 방향으로 적절히 배치함으로써, 별도 재료를 사용하거나 구성을 크게 변경하지 않으면서도, 열수축 차이에 의해 발생할 수 있는 단차를 방지하여 금속 멤브레인의 손상을 효율적으로 방지할 수 있다.
