Title (EN) SEALED AND THERMALLY INSULATING TANK COMPRISING A GAS DOME STRUCTURE
(FR) CUVE ETANCHE ET THERMIQUEMENT ISOLANTE COMPORTANT UNE STRUCTURE DE DOME GAZ
Abstract:
(EN) The invention concerns a sealed and thermally insulating tank, intended to store a liquefied gas, said tank comprising a top wall having a multilayer structure; the tank further comprising a gas dome structure (1) comprising: - a vapour collecting pipe (15); - a sheath (19) that is arranged around the vapour collecting pipe (15) and is sealingly connected to the secondary sealing membrane (6); said sheath (19) being sealingly linked to the vapour collecting pipe (15) by means of a top annular plate (20) that extends transversely between the sheath (19) and the vapour collecting pipe (15) in such a way as to provide a sealed primary space (22) that communicates with the primary thermally insulating barrier (7); the sheath (19) having, between the top annular plate (20) and the secondary sealing membrane (6), a frustoconical portion (43) tapering towards the secondary sealing membrane (6); and - a primary exhaust device intended to discharge a fluid from the primary thermally insulating barrier (7); the primary exhaust device comprising a pipe (27) sealingly connected to the top annular plate (20).
(FR) L'invention concerne une cuve étanche et thermiquement isolante, destinée à stocker un gaz liquéfié, ladite cuve comportant une paroi supérieure présentant une structure multicouche; la cuve comportant en outre une structure de dôme gaz (1) comportant : - une conduite collectrice de vapeur (15); - une gaine (19) qui est disposée autour de la conduite collectrice de vapeur (15) et est raccordée de manière étanche à la membrane d'étanchéité secondaire (6); ladite gaine (19) étant reliée de manière étanche à la conduite collectrice de vapeur (15) au moyen d'un plateau annulaire supérieur (20) qui s'étend transversalement entre la gaine (19) et la conduite collectrice de vapeur (15) de manière à ménager un espace primaire étanche (22) qui communique avec la barrière thermiquement isolante primaire (7); la gaine (19) présentant, entre le plateau annulaire supérieur (20) et la membrane d'étanchéité secondaire (6), une portion tronconique (43) se rétrécissant en direction de la membrane d'étanchéité secondaire (6); et - un dispositif d'échappement primaire destiné à évacuer un fluide de la barrière thermiquement isolante primaire (7); le dispositif d'échappement primaire comportant un conduit (27) raccordé de manière étanche au plateau annulaire supérieur (20).
