Abstract:
A fluidtight and thermally insulating tank wall comprises:a multi-layer structure comprising a fluidtight barrier (5) and a thermally insulating barrier (4), retaining rods (22) attached to the bearing wall (7) between the insulating elements and extending in the direction of the thickness of the multi-layer structure to hold the multi-layer structure on the bearing wall, in which crossmembers (30) are attached to the retaining rods (22) such that in each instance a crossmember extends between two retaining rods at the interface between two insulating elements, the cover panels (11) of the insulating elements being connected to the crossmembers (30) so as to be held against the bearing wall via the crossmembers, and the fluidtight barrier (5) being connected to the crossmembers (30) so as to be held against the cover panels of the insulating elements via the crossmembers.
Abstract:
An antirolling and antipitching device for a ship-borne spherical tank movably suspended from the ship''s hull and comprising at least one horizontal ring surrounding said tank and freely interposed between the latter and said hull, said ring being formed with radial guide elements engaging in vertically and radially horizontally sliding relationship corresponding slide means secured to said tank and to said hull, respectively.
Abstract:
A method of making a dihedron-like corrugated corner element from a metal sheet, comprising folding said sheet into a dihedron and forming therein a corrugation extending throughout transversely of the edge of the dihedron by driving in a portion of said sheet while simultaneously drawing near to each other the non-deformed sheet portions located on each side of the crest folding line of the corrugations.
Abstract:
A suspension device for a vehicle-borne rigid storage tank consisting of spaced fastening supports connected to the vehicle structure and to the tank. The supports are distributed horizontally about the tank. The connections between the supports and vehicle structure are provided by rigidly interconnected beams parallel with a horizontal plane of the vehicle and are arranged in a polygonal, convex configuration surrounding the tank.
Abstract:
A liquefied gas storage facility (1) has a load-bearing structure (10) having a bottom wall (11) and a vertical load-bearing wall (12) made up of N vertical load-bearing panels (14), and a tank comprising a bottom wall (21) and a vertical wall (22). The bottom wall (21) has a plurality of angular sectors. The corrugated sealing membrane (70, 170) of each angular sector (25) has first corrugations (72). The corrugated sealing membrane (70, 170) of each angular sector (25) has a plurality of metal plates (71) arranged to form ring portions (75). The ring portions (75) consist of a set of complete metal plates. The total number of first corrugations (72) present on the ring portions (75) increases in the direction of the vertical wall (22). The total number being increased only every M successive ring portions (75), where M is a natural integer greater than or equal to 2.
