Patent number: 11821587Abstract: 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.Type: GrantFiled: July 25, 2019Date of Patent: November 21, 2023Assignee: GAZTRANSPORT ET TECHNIGAZInventors: Mohammed Oulalite, Pierre Charbonnier, Mohamed Sassi, Marc Boyeau, Bruno Deletre, Raphaël Prunier
