Disclosed is an insulation structure of a cargo tank that forms a leak path for fluid flowing out through a damaged area of a primary barrier through an open cell layer surrounding the primary barrier and improves the insulation effect together with a closed cell layer and a protective layer. According to an embodiment of the present invention, an insulation structure of a cargo tank comprises: an open cell which that surrounds a primary barrier in contact with cryogenic fluid inside a cargo tank and forms a leak path so that the leaked fluid can flow through the primary barrier; a closed cell layer stacked on top of the open cell layer; and a protective layer stacked on top of the closed cell layer. In the open cell layer, support blocks for supporting a load acting on the protective layer are disposed at set intervals.

    화물창의 단열구조가 개시된다. 본 발명의 실시 예에 따른 화물창의 단열구조는 화물창 내부의 극저온 유체와 접촉되는 1차방벽을 감싸며, 1차방벽을 통해 누출된 유체가 흘러갈 수 있도록 리크패스를 형성하는 오픈셀층; 오픈셀층 상부에 적층된 클로즈드셀층; 및 클로즈드셀층 상부에 적층된 보호층;을 포함하되, 오픈셀층에는 보호층에 작용하는 하중을 지지하기 위한 지지블록이 설정 간격으로 배치된다.
