The present invention relates to a method of operating a membrane-type liquefied hydrogen storage tank, wherein a membrane-type liquefied hydrogen storage tank with a divided internal space comprises: a storage space in which a secondary barrier and a primary barrier made of metal are sequentially stacked on an inner wall of a hull and liquefied hydrogen is stored; a primary insulation space formed between the primary barrier and the secondary barrier; and a secondary insulation space formed between the secondary barrier and the hull. The method of operating the membrane-type liquefied hydrogen storage tank comprises: a vacuum forming step of forming vacuum in the storage space, the primary insulation space, and the secondary insulation space; a liquefied hydrogen shipping step of loading liquefied hydrogen into the storage space; and a helium gas injection step of injecting helium gas as inert gas into the primary insulation space and the secondary insulation space.

    본 발명은 선체 내벽면에 금속 재질의 2차 방벽 및 1차 방벽이 순차적으로 적층 배치되고, 액화수소가 저장되는 저장공간; 1차 방벽과 2차 방벽 사이에 형성되는 1차 단열공간; 및 2차 방벽과 선체 사이에 형성되는 2차 단열공간으로 내부 공간이 구분되는 멤브레인형 액화수소 저장탱크에 있어서, 저장공간, 1차 단열공간 및 2차 단열공간에 대하여 진공을 형성하는 진공 형성단계; 저장공간 내부에 액화수소를 로딩하는 액화수소 선적단계; 및 1차 단열공간 및 2차 단열공간에 불활성가스로서 헬륨가스를 주입하는 헬륨가스 주입단계를 포함하는, 멤브레인형 액화수소 저장탱크의 운용방법을 제공한다.
