Cryogenic insulation system for containers for storage of cryogenic liquefied gases such as LNG (liquid natural gas), comprised of a low temperature resistant metal, preferably high nickel steel, membrane or liner supported by a layer of reinforced foam insulation. There is provided at corners, for example at 90°corners, and disposed within the foam insulation layer, a corner structure comprised of a low temperature resistant metal, preferably high nickel steel, e.g. Invar, angle member, to which such membrane is attached, a support or back-up member for such angle member, a plurality of low thermal conductivity high strength metal, e.g. stainless steel, strips or fingers attached as by welding, to the angle member, such fingers being in the plane of the membrane, the fingers being attached at their outer ends to connectors which are attached to the container wall or ship hull. The fingers transmit loads from the metal membrane through the container wall or ship hull. An insulation support panel is provided for supporting the foam insulation at the corner. This application is a continuation, of application Ser. No. 909,929, filed May 26, 1878 now abandoned.

A container for cryogenic liquefied gases which comprises a container wall, at least one fiber reinforced foam insulation layer disposed within said container wall, a low temperature resistant low thermal expansion metal liner in contact with the inner side of said at least one foam insulation layer
A container for cryogenic liquefied gases which comprises a container wall, at least one fiber reinforced foam insulation layer disposed within said container wall, a low temperature resistant low thermal expansion metal liner in contact with the inner side of said at least one foam insulation layer, said container having corners and including at least one corner structure, said corner structure comprising a corner support, said corner support being disposed in said at least one foam insulation layer adjacent said metal liner at said corner of said container wall, a low temperature resistant low thermal expansion metal angle member, means connecting said metal liner to said angle member, means connecting said angle member to said corner support, a plurality of metal strips, means connecting said metal strips adjacent one end therof to said angle member, and means connecting said metal strips adjacent the other end thereof to the wall of said container, said strips comprised of a metal having low thermal conductivity and high strength, said strips transmitting loads from only one face of said metal liner at said corner to the wall of said container, said plurality of metal strips consisting of spaced substantially parallel strips, all of said strips being substantially in the plane of said one face of said liner in only one direction thereof at said corner, said metal liner comprising a plurality of parallel strakes, said strakes having upstanding flanges along their longitudinal edges, the flanges of adjacent strakes being connected together, the flanges of said metal liner in said one face of said liner in said one direction thereof at said corner being perpendicular to the corner, and the flanges of said metal liner in another face of said liner in another direction thereof at said corner being parallel to said corner.
