Abstract: An upright tank of cylindrical or prismatic form has a sealed inner wall surrounded by insulation, and an outer casing. The bottom of the inner wall is formed from parallel strips of INVAR welded together at inturned flanged edges and is mounted in sliding relation to insulation beneath the bottom. The inner side wall is formed from parallel vertical bands of stainless steel with inwardly bent margins welded together and slidingly supported vertically to permit expansion and contraction. The inner side wall is joined to the inner bottom wall by a corner angle assembly including sheets and angles of INVAR supported by an annular beam. The annular beam includes straight beam sections supported at their ends by gussets which in turn are anchored to the exterior casing of the tank.

Abstract: Apparatus for transporting liquified gas at low temperature, a supporting structure containing a self-supporting fluid-type tank, an annular supporting ring, an annular plate, comprising a plurality of sliding joints between said annular plate and ring which permit said ring to expand and contract radially with respect to said plate.

Abstract: An improvement in fluid-tight isothermal tanks for holding liquefied gas and comprising sealing barriers of thin metal alternated with heat insulating barriers, the edges of two sealing barriers which intersect at a corner of the tank being connected by a deformable ring having an L-shaped section, with each flange comprising a strip of the same metal as said barrier attached to a plurality of spaced modules of heat insulating material, and the ring being fastened to an external supporting structure by draw bolts passing through the spaces between the modules.

Abstract: Ship having heat insulating compartments built into the framework of the ship has successive first sealing, first insulating, second sealing and second insulating barriers forming the compartment wall. The second sealing barrier is held to the hull of the ship by a fastener passing through the second insulating barrier. This fastener comprises an elongated stud welded to the hull of the ship, a head carried by the stud and a member fixed to the second insulating barrier and fastened to the head. The arrangement is such as to permit relative movement between the second insulating barrier and the hull substantially parallel to the hull.
