The present invention relates to an insulation system of a liquefied gas cargo hold. The present invention sets a thickness of a primary insulation layer to be less than 10% of the thickness of a secondary insulation layer and has a cross-shaped fixing unit fixating a membrane and the primary insulation layer together to improve a fixing structure of the primary insulation layer and a sealing structure of the membrane in order to reduce the weight of a cargo hold and slim down the cargo hold and maintain structural strength and insulation property. Moreover, a manufacturing process of the cargo hold is simplified to improve workability and reduce production costs.
본 발명은 액화가스 화물창의 단열 시스템에 관한 것으로, 1차 단열층의 두께를 2차 단열층의 두께 대비 10% 이내로 설정하고, 멤브레인과 1차 단열층을 함께 고정할 수 있는 십자형의 고정유닛(membrane and insulation securing unit)을 설치하여 1차 단열층의 고정구조와 멤브레인 밀봉구조를 개선함으로써, 경량화 및 슬림화를 구현하면서도 구조적 강성과 단열성능을 유지할 수 있음은 물론 화물창 제조 공정이 단순화되어 작업성을 향상시키고 생산원가를 절감할 수 있다.
