Abstract: A liquefied gas storage facility has a through-structure positioned in a passage extending through a load-bearing roof wall and a tank wall. The through-structure has a main envelope sealingly delimiting an internal space at an absolute pressure of less than 10 Pa. The main envelope has a central portion, an inner portion, an outer portion, and an outer peripheral fastening element connecting the outer portion to the load-bearing roof wall. A closure wall extends around and at a distance from the central portion. The closure wall sealingly connects the outer peripheral fastening element to a sealed membrane. The sealed membrane is sealingly fastened to an inner peripheral fastening element. The through-structure also has a sealed pipe.

Abstract: The invention relates to a wall (11) comprising an insulating barrier (14) intended to rest against a load-bearing structure and a sealing membrane (15) which rests against the insulating barrier, the insulating barrier comprising: a support element (30) and a modular structure situated between the support element and the sealing membrane, the modular structure being fixed against the support element, the sealing membrane resting against the modular structure and being fixed to said modular structure, the modular structure comprising a first and a second sheet, the sealing membrane comprising a first zone fixed to the first sheet and a second zone fixed to the second sheet, the first sheet being connected to the second sheet by a connection that offers a degree of freedom in translation in a direction perpendicular to the thickness direction of the wall and a degree of connection in the thickness direction of the wall.

Abstract: A wall of a tank for storing at least one fluid, the wall includes a shell and at least one panel kept at a distance from the shell by at least one anchoring element holding the panel relative to the shell by defining an area between the shell and the panel, the area being at least partially filled with a filling material, the wall includes a sealing membrane bearing against the panel arranged opposite the filling material relative to the panel.
