The present invention relates to an LNG tank of an LNG carrier where LNG is stored. The LNG tank comprises: a membrane layer which absorbs the load of fluid stored inside; a heat insulating layer; and an outer wall layer. The heat insulating layer is composed of two heat insulating layers and a reinforcement plate installed between the heat insulating layers. At least one of the heat insulating layers is formed by successively stacking heat insulating plates having plate-shaped structures, wherein each of the heat insulating plates is formed by alternately bonding insulation beams made of different materials to each other. Therefore, the present invention has excellent mechanical strength and heat insulation performance through the complementary action of the insulation beams, thereby securing the safety and reliability of the LNG tank.

    본 발명은 엘엔지가 저장되는 엘엔지 운반선의 엘엔지 화물창에 관한 것으로서, 내부에 저장된 유체의 하중을 흡수하는 멤브레인층과 보온층 및 외벽층으로 이루어진 엘엔지 화물창에 있어서, 상기 보온층은 두 개의 단열층과 상기 단열층 사이에 설치되는 보강판으로 이루어지고, 상기 단열층 중 적어도 어느 하나는 서로 다른 이종 재질의 단열빔이 교대로 접착되어 형성된 판상 구조의 단열판을 순차적으로 다수개 적층하여 이루어지도록 하되, 상기 각각의 단열판은 상기 단열빔이 서로 교차 배치되도록 적층함으로써, 두 단열재의 상호 보완 작용을 통해 기계적 강도는 물론 단열 성능 또한 우수한 화물창을 제공하여 화물창의 안전성과 신뢰성을 확보할 수 있는 엘엔지 화물창에 관한 것이다.
