The present invention relates to a construction method for finishing an insulation system of a membrane-type cargo hold in a liquefied natural gas carrier, wherein the cargo hold has a primary and a secondary barrier to both of which a metallic membrane is applied for enhancing performance of the cargo hold, and both of which are composed of a corrugated membrane, to ensure a noble type work passage design and finishing method, adopts a method of minimally cutting a membrane and an insulation panel installed near the work passage of the cargo hold to perform a finishing construction, and adopts a method of forming the primary and secondary barrier by directly welding a straight bar type temporary membrane, thereby being capable of efficiently performing an airtight test and a finishing process of the primary and the secondary barrier, and simplifying a finishing process and remarkably reducing a construction period.

    본 발명은 멤브레인형 액화천연가스 운반선의 화물창 단열시스템 마감 시공방법에 관한 것으로, 화물창 성능향상을 위해 일차 및 이차 방벽 모두에 금속재질의 멤브레인을 적용하며, 일차 및 이차 방벽이 모두 코러게이티드(corrugated) 멤브레인으로 구성된 화물창에서, 새로운 형태의 작업통로의 설계 및 마감 방안 확립이 필수적인바, 화물창의 작업통로 인근에 설치된 멤브레인 및 단열패널을 최소한으로 절단하여 마감 시공하는 방식을 채택하며, 일차 및 이차방벽 모두 직선 바(straight bar) 형태의 임시 방벽(temporary membrane)을 직접 용접하는 방법을 채택함으로써, 일차 및 이차 방벽의 기밀시험과 마감공정을 효율적으로 수행할 수 있으며, 간단한 마감 처리가 가능하고, 공사 기간을 대폭 단축할 수 있다.
