The present invention relates to a cargo tank structure and a marine structure having the same, wherein a secondary barrier structure is formed with an external barrier forming an internal wall of a hull and an internal barrier in which liquefied gas is stored, and further, an insulation member is coupled to an internal surface of the external barrier to form one or a plurality of insulating layers. Therefore, the insulation member is not exposed to the outside of a tank to minimize dangerousness of fire in case of construction. Moreover, the insulation member is placed within a thickness of the tank to increase a size of the tank, and when forming the insulation member in multiple stages, insulation performance and strength of the tank can be more improved.

    본 발명은 선체의 내벽을 형성하는 외측 방벽과 액화가스가 저장되는 내측 방벽을 이용해 2차 방벽 구조를 형성시킴과 아울러, 외측 방벽의 내면에 단열부재를 결합시켜 하나 또는 다수의 단열층을 형성시킴으로써, 탱크의 외부에 단열부재가 노출되지 않으므로 건조시 화재의 위험성을 최소화할 수 있고, 단열부재가 탱크의 두께 내에 위치되므로 탱크의 사이즈를 증가시킬 수 있으며, 단열부재를 다단으로 구성하는 경우 탱크의 단열 성능 및 강도를 더욱 향상시킬 수 있는 카고 탱크 구조 및 이를 갖는 해양구조물에 관한 것이다.
