Moss Rossenberg system
The LNG cargo containment system developed by Moss Rosenberg Verft. The system features self-supporting spherical tanks connected at the equator to a single cylindrical supporting skirt, the lower portion of which is welded to the ship structure. The tanks are made of aluminium alloy, with internal diameters of up to and above 40m and a shell thickness of up to 50mm. Insulation (of polyurethane, styrofoam or equivalent) is arranged over the tank outer surface and the upper part of the skirt.
