Installation method of panel for corner area of LNG tank and panel for corner area of LNG tank

摘要

PURPOSE: A corner panel of a LNG storage tank and an installation method thereof are provided to stably attach an upper panel on a lower panel even if the lower panel is a complex shape. CONSTITUTION: A method for installing a corner panel of a LNG storage tank includes next steps. A bent lower panel corresponding to a corner is provided(S110). A first leak barrier is laminated on the lower panel(S120). A space part is formed in the center of the first leak barrier to support the edge of an upper panel. The first leak barrier prevents LNG gas leakage. The upper panel is attached on the first leak barrier(S130). The lower panel on which the upper panel is attached is installed at the corner of a storage tank.
