Abstract (en)
[origin: WO2005095234A1] A metal membrane panel of an insulated LNG cargo tank, which has an improved stability by decreasing localized stress concentration areas, and which has an improved welding efficiency by reducing the number of corrugations on welding edges of adjacent metal membrane panel to reduce the number of curved portions to be welded. The metal membrane panel includes a plurality of rectangular unit corrugations (10) arranged on the panel (A) to be spaced from each other, each of the rectangular unit corrugations (10) being comprised of a pair of transverse bulging portions (12) and a pair of longitudinal bulging portions (11) and being shaped to have gently curved corners, transverse and longitudinal connecting corrugations (40, 50), which connect the plurality of rectangular unit corrugations (10) to each other, and transverse and longitudinal extending corrugations (60, 60'), which are extended to edges of the metal membrane panel (A) from the transverse and longitudinal bulging portions (12, 11) of the outermost unit corrugations (10).
