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 attached to the primary layer of foam insulation by tongues of high nickel steel connected to the primary membrane at spaced positions therealong, and engaged in plywood retainers positioned within and bonded to the primary foam insulation layer. The plywood retainers for such tongues include spaces or channels in communication with a manifold for detection of cryogenic gas leakage. 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 plastic coupler, threaded rod and plywood supports, the plywood supports being attached to the primary high nickel steel liner and the coupler to the container wall or shi…
