Abstract: A tank includes a secondary insulation barrier, a secondary sealing membrane resting on the secondary insulation barrier, a primary insulation barrier resting on the secondary sealing membrane, a primary sealing membrane resting on the primary insulation barrier, and a primary reinforcing member. The primary sealing membrane includes primary corrugations and the secondary sealing membrane includes secondary corrugations projecting toward the interior of the tank. The primary and secondary corrugations are superimposed along a thickness direction. The primary insulation barrier has passages, and the secondary corrugations are accommodated in the passages. A dimension of the primary insulation barrier is less than a dimension of the secondary corrugations along the thickness direction, so the secondary corrugations extend through the passages and are partially accommodated in the primary corrugations.

Abstract: The invention relates to a fluid storage facility, the storage facility comprising a supporting structure (1) and a tank, the tank having at least one tank bottom wall fixed to the supporting structure (1), wherein the bottom wall has a structure with multiple layers superimposed in a direction of thickness, including at least one sealing membrane and at least one thermal insulation barrier arranged between the sealing membrane and the supporting structure (1), wherein the bottom wall has a sump structure (9) having a rigid container (10, 11) comprising a side wall (12), the container (10, 11) being arranged through the thickness of the bottom wall, and the sump structure (9) comprising at least one fixing means (15) designed to fix the rigid container (11) to the supporting structure (1) at a fixing point, and wherein the at least one fixing means (15) is configured to allow the relative movement of the side wall (12) of the container (11) with respect to the supporting structure (1) in a transverse directi

Abstract: A sealed and thermally insulating storage tank for a fluid that is anchored in a load-bearing structure built into a ship, the ship having a longitudinal direction, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the loading/unloading tower including first, second and third vertical pylons defining a prism of triangular section, the loading/unloading tower carrying at least a first pump, the tank having a support foot that is fastened to the load-bearing structure, the tank having at least one sump, the first pump being arranged outside the triangular prism and being aligned with the support foot in a first transverse plane that is orthogonal to the longitudinal direction of the ship.

Abstract: The invention concerns a sealed tank including adjacent first and second walls each comprising a corrugated sealing membrane. The sealing membranes of the first and second walls join at the level of an edge, wherein the sealing membrane of the first wall includes a first series of corrugations and a second series of corrugations intersecting at the edge, and the sealing membrane of the second wall includes a third series of corrugations intersecting at the edge. The tank further includes a corner arrangement comprising a sealing membrane that is welded in sealed manner to the sealing membrane of the first wall and to the sealing membrane of the second wall, such that the corrugations of the first series of corrugations are connected to corrugations of the third series of corrugations and the corrugations of the second series of corrugations are connected to the corrugations of the third series of corrugations.
