ABSTRACT:
A marine container for holding liquefied gas wherein a metal tank having the general shape of a surface of revolution is designed to contain a liquefied gas by maintaining a low temperature therewithin via a surrounding thermal insulation barrier. A first layer of foamed polymeric panels, each having a predetermined hole pattern, are supported by studs affixed to said exterior surface and extending into the holes. Fibrous insulation fills the remainder of the holes and the joints between the edges of adjacent panels. Heat-insulating posts extend outward from the studs and support a layer of fibrous insulation and a third layer of foamed polymeric panels having an offset hole pattern. Fasteners secure the third layer panels upon the posts. Insulating material is foamed in situ through apertures in the fasteners to fill the holes around the posts.
