Definitions
- the invention relates to the field of sealed and thermally insulating tanks for the storage and/or transport of a liquefied gas, such as tanks for the transport of Liquefied Petroleum Gas (also called LPG) having for example a temperature between between -50°C and 0°C, or for transporting Liquefied Natural Gas (LNG) at approximately -163°C at atmospheric pressure.
- LPG Liquefied Petroleum Gas
- LNG Liquefied Natural Gas
- tanks can be installed on land or on a floating structure.
- the tank may be intended for the transport of liquefied gas or to receive liquefied gas used as fuel for the propulsion of the floating structure.
- a sealed and thermally insulating vessel comprising a vessel wall retained on a supporting structure, the vessel wall including, in the direction of the thickness from the outside towards the inside of the vessel , a secondary thermally insulating barrier retained on the supporting structure, a secondary waterproof membrane retained on the secondary thermally insulating barrier, a primary thermally insulating barrier retained on the secondary waterproof membrane and a corrugated primary waterproof membrane retained on the primary thermally insulating barrier.
- a sealed and thermally insulating tank can in particular be used in the transport of liquefied gas, such as liquefied natural gas (LNG), in particular on board a floating structure, such as a ship.
- LNG liquefied natural gas
- the primary waterproof membrane It is known to produce the primary waterproof membrane by assembling a plurality of sheets which have undulations, advantageously perpendicular to each other.
- the corrugations give the primary sealed membrane a flexibility allowing it to deform under the effect of thermal and mechanical stresses and in particular those generated by the liquefied gas stored in the tank and those related to the deformation of the supporting structure.
- the primary waterproof membrane is anchored to the insulating panels of the primary thermally insulating barrier. To do this, each sheet is arranged astride several insulating panels of the primary thermally insulating barrier. Furthermore, the sheets are welded to each other along their edges and are also welded along their edges to anchoring elements which are attached to said insulating panels. More specifically, the sheets are welded to anchoring elements which are arranged along the edges of the sheets, on either side of each corrugation.
- the undulations of the primary sealed membrane were not stressed uniformly.
- the primary thermally insulating barrier is discontinuous, that is to say that it consists of insulating panels juxtaposed to each other, its behavior is not homogeneous when the load-bearing structure deforms and / or under the effect of thermal and mechanical stresses generated by the liquefied gas stored in the tank.
- the undulations which are arranged in a zone straddling a first anchoring element fixed to a first insulating panel and a second anchoring element fixed to a second insulating panel are stressed in a greater way than others.
- One idea underlying the invention is to propose a sealed and thermally insulating tank in which the stresses undergone by the primary sealed membrane are more evenly distributed between the undulations thereof.
- the invention relates to a wall of a sealed and thermally insulating tank for storing a liquefied gas, said wall comprising at least one thermally insulating barrier and a sealed membrane which is anchored to said thermally insulating barrier and is intended to be in contact with the liquefied gas, the thermally insulating barrier comprising a first insulating panel and a second insulating panel arranged along a first edge of the first insulating panel, the first and second insulating panels being respectively equipped with at at least one first anchoring element and at least one second anchoring element to which the waterproof membrane is welded; the waterproof membrane comprising corrugations separated from each other by flat portions and in which at least one of the flat portions is arranged astride the first and the second insulating panels and is welded on the one hand to the first element of anchoring and on the other hand to the second anchoring element.
- the plane portion of the waterproof membrane which is arranged astride between the adjacent insulating panels, performs a function of mechanical connection between the insulating panels. This prevents the mutual spacing of said insulating panels and contributes to more evenly distributing the deformation of the load-bearing structure over the primary thermally insulating barrier.
- the behavior of the assembly consisting of the thermally insulating barrier and the waterproof membrane is here dictated by the fact that the insulating panels have overall a lower stiffness than that of the waterproof membrane. It is therefore the deformations of the waterproof membrane that condition those of the insulating panels. This therefore makes it possible to stress the undulations of the waterproof membrane in a more homogeneous manner.
- such a vessel wall may comprise one or more of the following characteristics.
- the stiffness of the first and second insulating panels is less than the stiffness of a flat portion of the waterproof membrane. This ensures that the deformations of the thermally insulating barrier are imposed by the deformations of the waterproof membrane.

- each primary panel 7 has relaxation slots 21 which each extend opposite a respective corrugation 17, 18 of the primary waterproof membrane 8. These relaxation slots 21 make it possible to take full advantage of the corrugations 17, 18 since they allow the primary waterproof membrane 8 to deform without imposing excessive mechanical stresses on the primary panels 7.
- each primary panel 7 faces three corrugations 17 extending parallel to a first direction and three corrugations 18 extending parallel to a second direction perpendicular to the first direction.

- each central axis is parallel to two opposite edges of the corrugated metal sheet 16 and divides it into two equal portions. More particularly, each corrugation 17, 18 which is adjacent and parallel to one of the edges intended to be covered by an edge of another corrugated metal sheet 16 is placed at a greater distance d1 or d2 from the adjacent edge than the distance d3, d4 between the corrugation 17, 18, which is adjacent and parallel to the opposite edge which is intended to cover an edge of an adjacent metal sheet, and said opposite edge.
