The present invention relates to a liquefied gas storage tank and a marine structure including the same. According to the present invention, the liquefied gas storage tank comprises: a first protective wall which comes in contact with liquefied gas; a first insulation wall which is installed in the first protective wall; a second protective wall which is installed in the first insulation wall; a second insulation wall which is installed in between the second protective wall and a hull and which comprises: a second insulation panel; and a second plywood; and an insulation shield which is installed in between the second insulation panel and the hull. The insulation shield is made from liquid insulation materials. According to the present invention, the liquefied gas storage tank and the marine structure including the same can have the insulation shield installed between the second insulation panel and the second plywood, which make the second insulation wall have improved insulation performance, reduce the BOR, and enhance reliability of the liquefied gas storage tank, and can form the insulation shield by coating the surface of the second plywood with the liquid insulation materials to unify the second plywood and the insulation shield and to increase the strength of the second insulation wall.
본 발명은 액화가스 저장탱크 및 이를 구비한 해양구조물에 관한 것으로서, 본 발명에 따른 액화가스 저장탱크는, 액화가스와 접촉하는 1차 방벽; 상기 1차 방벽에 설치되는 1차 단열벽; 상기 1차 단열벽에 설치되는 2차 방벽; 상기 2차 방벽과 선체 사이에 설치되며, 2차 단열패널과 2차 플라이우드를 포함하는 2차 단열벽; 및 상기 2차 단열패널로부터 상기 선체 사이에 설치되는 단열실드를 포함하되, 상기 단열실드는 액상단열재로 형성되는 것을 특징으로 한다. 본 발명에 따른 액화가스 저장탱크 및 이를 구비한 해양구조물은, 2차 단열벽을 이루는 2차 단열패널과 2차 플라이우드 사이에 단열실드를 설치함으로써, 2차 단열벽의 단열성능을 더욱 향상시킬 수 있어, BOR을 저감시킬 수 있고, 액화가스 저장탱크의 신뢰성을 향상시킬 수 있고, 2차 플라이우드의 표면에 액상단열재를 코팅하여 단열실드를 형성함으로써, 2차 플라이우드에 단열실드가 일체화되어 2차 단열벽의 강성을 향상시킬 수 있다.
