The present invention relates to an insulation system of a cryogenic fluid storage tank and an LNG carrier ship having the same, and more specifically, to an insulation system of a cryogenic fluid storage tank and an LNG carrier ship having the same which replace an insulation box which is a structural material and an insulation material filled in the insulation box with a perlite block to eliminate a need for an additional structural material which contributes to heat transfer to reduce thermal conductivity, reduce evaporation gas produced in a storage tank, and simplify a manufacturing process of the storage tank by integrating the structural material and the insulation material. The insulation system of a cryogenic fluid storage tank comprises: a first insulation layer to firstly insulate cryogenic fluid; and a second insulation layer which is installed between the first insulation layer and an inner wall of a ship hull, and secondly insulates the cryogenic fluid. The first insulation layer consists of a perlite block which is perlite hardened into a block shape.

    본 발명은 초저온 유체 저장탱크의 단열 시스템 및 이를 가지는 LNG 운반선에 관한 것으로서, 더욱 구체적으로는 구조재인 단열박스와 이에 채워지는 단열재를 펄라이트 블록으로 대체함으로써 열전달에 기여하던 별도의 구조재를 필요로 하지 않도록 하고, 이로 인해 열전도율을 감소시킬 뿐만 아니라, 저장탱크 내의 증발가스 발생을 저감시킬 수 있으며, 구조재와 단열재의 일체형으로 인해 저장탱크의 제작공정을 단순화시킬 수 있는 초저온 유체 저장탱크의 단열 시스템 및 이를 가지는 LNG 운반선에 관한 것이다. 본 발명은 초저온 유체 저장탱크의 단열시스템에 있어서, 초저온 유체를 1차적으로 단열시키는 1차 단열층; 및 상기 1차 단열층과 선체의 내벽 사이에 설치되고, 상기 초저온 유체를 2차적으로 단열시키는 2차 단열층을 포함하되, 상기 1차 단열층은, 펄라이트(perlite)를 블록 형태로 경화시킨 펄라이트 블록으로 이루어진다.
