Abstract
Cryogenic insulation system for containers for storage of cryogenic liquefied gases such as LNG, comprised of a low temperature resistant metal, preferably high nickel steel, primary membrane or liner supported by a primary layer of reinforced foam insulation, and a secondary liner positioned adjacent to and sandwiched between the primary layer of foam insulation and a secondary layer of reinforced foam insulation. The preferably high nickel steel primary liner or membrane is supported above the primary foam insulation layer by stiffened ends of the reinforcement fibers which extend above the surface of the foam insulation, providing a small gap between the foam and the membrane. There is provided at corners, particularly at 90.degree. corners, and disposed within the primary and secondary foam insulation layers, a cooperating system of a coupler attached to the container wall or ship hull, ball joint coupler bolt and plywood support attached to the primary high nickel steel liner, to transfer loads from the liner to the container wall or ship hull, while permitting the corner structure to move under loads applied by the liner. Insulation support panels are provided for supporting …
