Definitions

  • the invention relates to the field of sealed and thermally insulating tanks with membranes.
  • the invention relates to the field of sealed and thermally insulating tanks for the storage and / or transport of liquid at low temperature, such as tanks for the transport of liquefied petroleum gas (also called LPG) having, for example a temperature between -50 ° C and 0 ° C, or for the transport of Liquefied Natural Gas (LNG) at about -162 ° C at atmospheric pressure.
  • LPG liquefied petroleum gas
  • LNG Liquefied Natural Gas
  • the patent application FR-A-2781557 discloses a sealed and thermally insulating tank with a double waterproof membrane integrated in a supporting structure, in particular a ship.
  • the two watertight membranes are separated from each other and from the supporting structure by two thermally insulating barriers.
  • the secondary membrane is made by the juxtaposition of adjacent panels whose sealing is provided by flexible strips gas-tight and liquid and may comprise at least one thin deformable continuous metal sheet.
  • the band which covers the junction zone between the two elements of the secondary membrane is free to deform elastically and / or to extend relative to the insulating blocks held on the walls of the bearing structure with a limited freedom of movement .
  • a wall structure for producing the flat wall of a sealed double-diaphragm tank undergoes significant constraints in service, related to the different loadings of the tank, thermal contraction, movements of cargo, deformation of the carrier structure to the swell. These constraints are in particular transmitted by the thermally insulating barrier on which the secondary waterproof membrane is anchored. Because the thermally insulating barrier consists of discrete insulating panels of large dimensions, the stresses and displacements that are transmitted to the secondary waterproof membrane are not uniformly distributed, so that the corrugations of the secondary waterproof membrane are solicited in different ways. depending on whether they are near the edges of the panels or near the center. In addition, the flexibility of certain undulations is limited by anchoring the edges of the metal plates on the panels. This results in stress concentrations that can accelerate the aging of the sealed membrane. These problems would also exist if the primary membrane was removed.
  • bridging elements disposed between the secondary insulating panels serve to improve the distribution of displacements by limiting the spacing movements of the edges of the panels. These bridging elements may respond to some extent to panel edge spreading movements but are limited, complex to install and have a relatively high installation cost.
  • One idea underlying the invention is to provide a membrane wall structure that solves at least some of these disadvantages.
