Abstract:
The invention relates to a sealed and thermally insulating tank intended to store a fluid, said tank comprising: - a secondary insulating barrier (1) comprising juxtaposed insulating panels (2, 2a, 2b, 2c, 2d); - a primary insulating barrier (5) comprising insulating panels (6, 6a, 6b, 6c) which are each disposed in a manner straddling at least four secondary insulating panels (2, 2a, 2b, 2c, 2d) and are anchored to the latter; the sealed tank being equipped with a through-element (42) passing through a specific zone of the wall; in the specific zone of the wall, the longitudinal directions of the primary panels (6a, 6b, 6c) being perpendicular to the longitudinal directions of the secondary insulating panels (2a, 2b, 2c, 2d); and the through-element (42) passes successively through an opening made in one of the secondary insulating panels (2c) and an opening made in one of the primary insulating panels (6b).
