  • the plates 1, 2, 3, 4 each comprise at least two perpendicular undulations so as to allow the membrane to deform under the effect of the thermal and mechanical stresses generated by the fluid stored in the tank.
  • the technique described above for making a sealing membrane can be used in different types of tanks, for example to constitute the primary sealing membrane and/or the secondary sealing membrane of an LNG storage tank in an installation on land or in a floating structure such as an LNG carrier or other.
  • a cutaway view of an LNG carrier 70 shows a sealed and insulated tank 71 of generally prismatic shape mounted in the double hull 72 of the ship.
  • the wall of the tank 71 comprises a primary waterproof membrane intended to be in contact with the LNG contained in the tank, a secondary waterproof membrane arranged between the primary waterproof barrier and the double hull 72 of the ship, and two insulating barriers arranged respectively between the primary waterproof membrane and the secondary waterproof membrane and between the secondary waterproof membrane and the double hull 72.
  • loading/unloading pipes 73 arranged on the upper deck of the ship can be connected, by means of appropriate connectors, to a maritime or port terminal to transfer a cargo of LNG from or to the tank 71.
  • the figure 5 represents an example of a maritime terminal comprising a loading and unloading station 75, an underwater pipeline 76 and an installation on land 77.
  • the loading and unloading station 75 is a fixed offshore installation comprising a mobile arm 74 and a tower 78 which supports the mobile arm 74.
  • the mobile arm 74 carries a bundle of insulated flexible pipes 79 which can be connected to the loading/unloading pipes 73.
  • the orientable mobile arm 74 adapts to all sizes of LNG carriers.
  • a connecting pipe, not shown, extends inside the tower 78.
  • the loading and unloading station 75 allows the loading and unloading of the LNG carrier 70 from or to the shore installation 77.
  • This comprises liquefied gas storage tanks 80 and connecting pipes 81 connected by the underwater pipe 76 to the loading or unloading station 75.
  • the underwater pipe 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the shore installation 77 over a great distance, for example 5 km, which makes it possible to keep the LNG carrier 70 at a great distance from the coast during loading and unloading operations.
  • pumps on board the ship 70 and/or pumps fitted to the shore installation 77 and/or pumps fitted to the loading and unloading station 75 are used.
