Cryogenic insulation system

Patent ·
OSTI ID:6929336
McDonnell Douglas Corp.'s LNG-containment system uses an inexpensive support structure to protect the primary nickel steel membrane against rupture or failure due to thermal and mechanical strains caused by loading and unloading the cryogenic liquid. The system also incorporates a novel corner support system t o react against the tension and bending of the primary liner caused by thermal stresses. The primary membrane is connected to the adjacent foam insulation by a tongue arrangement in which the tongues are received and held in place by retainers positioned within the insulation. At 90/sup 0/ corners, a system of insulating rods and couplers reacts against plywood corner supports to transmit the tension loads from the primary membrane to the outer wall or hull of the tank or ship. Panels for supporting the insulation system against the container wall or ship hull employ adhesive plastic beads or modules cured to form a rigid load-carrying base for the support panels.
