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;the sealing membrane of the first wall including a first series of corrugations and a second series of corrugations intersecting at the edge; the sealing membrane of the second wall including a third series of corrugations intersecting at the edge; the tank further including 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 and is 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.

Abstract: A sealed and thermally insulating tank for storing a low-temperature liquefied gas, having an insulating box-section with a bottom panel coming into abutment on a support wall, by means of sealant beads disposed between the support wall and the bottom panel, the sealant beads being disposed in the form of at least one closed outline delimiting at least one confined space between the support wall and the bottom panel, the bottom panel having at least one through passage leading into the confined space to allow gas to circulate between the confined space and an internal space of the insulating box-section.
