An objective of the present invention is to provide a membrane-type liquefied gas insulation system capable of securing better performance than a conventional technique in the aspect of both insulation and airtightness. The membrane-type liquefied gas insulation system of a double metal barrier structure comprises: a secondary insulation layer consisting of a plurality of secondary insulation panels arranged on an inner wall of a storage container; a secondary membrane installed on an upper portion of the secondary insulation layer; a primary insulation layer consisting of a plurality of primary insulation panels arranged on the secondary membrane; a primary membrane installed on an upper portion of the primary insulation layer; and a fixing device installed to penetrate the secondary insulation panels from the inner wall of the storage container to fix the primary insulation panels. The fixing device includes: a base socket installed on the inner wall of the storage container; a lower rod coupled to the base socket by a ball joint and penetrating the secondary insulation panels to be extended upwards; a connector coupled to the upper end of the lower rod and mounted on the upper surface of the secondary insulation panels; an upper rod coupled to a socket provided on an upper portion of the connector by a ball joint and extended upwards; a flat washer inserted into the upper rod and supported on the surface layer of a lower portion of the primary insulation panels to vertically restrict the primary insulation panels; and a fixing nut fastened to the upper rod to fix the flat washer.
