- the tank wall is successively composed in its thickness of a secondary insulating barrier 2 which is formed of parallelepiped insulating elements 3 juxtaposed on the double shell 1 and retained thereon by secondary retaining members 4; then a secondary waterproof membrane 5 carried by the secondary insulating elements 3; then a primary insulating barrier 6 formed of parallelepiped insulating elements 7 juxtaposed and retained on the secondary waterproof membrane 5 by primary retaining members 8 themselves attached to the secondary retaining members 4 and, finally, a waterproof membrane primary 9 carried by the primary insulating elements 7.
- the membranes 5 and 9 are identically constituted by a continuous sheet of steel strakes with a high nickel content, for example 36%, known under the name of invar, which are welded in leakproof ways by their lateral edges raised on supports parallel welds fixed each time on the cover panels of the insulating elements 3 and 7 respectively, according to the known technique.
- the secondary insulating elements 3 are for example made in the form of plywood boxes filled with perlite, or in other forms known to those skilled in the art.
- the primary insulating elements 7 will now be described with reference to FIG.
- the primary insulating element 7 shown in Figure 2 rests on the secondary waterproof membrane 5, which is supported by a secondary insulating element 2 underlying, of which only the cover panel 10 is shown.
- the welding supports January 1 of the secondary waterproof membrane 5 are retained on the cover panel 10 being housed in parallel grooves 12, according to the known technique.
- the emergent part of the weld support 11 and the raised edges 13 which are welded to it on either side form the projections 14 of the secondary waterproof membrane 5.
- the primary insulating element 7 has a general rectangular parallelepiped shape with, for example, a length of about 1.2 m, a width of about 1 m and a height of about 200 mm. It comprises a box 20 and a pad of insulating material 30 glued or stapled or otherwise attached under the bottom panel 21 of the box 20.
- the box 20 is formed of plywood planks assembled by staples.
- Four lateral webs 23 are fixed perpendicularly to the periphery of the bottom panel 21 and extend to the inner surface of the cover panel 22, so as to close the interior space of the box 20 of parallelepiped shape.
- the cover panel 22 is preferably formed of two superimposed boards and bonded together having an equal thickness. Fastening lugs 24 are glued and stapled against the side sails 23.
- the fixing lugs 24 serve as bearing surface for the primary retaining members 8.
- the box 20 has parallel internal partitions 25 which are fixed perpendicularly to the bottom panel 21 and extend parallel to the two side walls 23 shown in Figure 2 between the two other side walls not shown in Figure 2 to which they are also attached at their two ends.
- the partitions 25 are arranged at regular intervals along the longitudinal direction of the box 20.
- These internal partitions 25 divide the internal space of the box 20 into identical compartments 26 which are filled with a heat-insulating seal such as expanded perlite. or any other suitable material.
- a heat-insulating seal such as expanded perlite. or any other suitable material.
- the box 20 may also include a positioning comb, not shown, arranged perpendicularly to the internal partitions 25 at mid-length thereof, according to the known technique.

- It can be made of polyurethane foam, optionally reinforced with glass fibers, or other synthetic materials, for example polystyrene or natural material, for example balsa.
- a criterion for selecting the insulating material is its good resistance in compression to avoid damaging the insulating pad or the box in use.
- the thickness of the pad 30 is greater than the height of the protruding portions 14 of the secondary waterproof membrane 5.
- the welding supports of the secondary waterproof membrane 5 may have a nominal height of about 35 mm.
- Notches 31 are formed in its thickness to accommodate these protruding portions 14 when the insulating member 7 is placed on the secondary waterproof membrane 5. In this way, these protruding portions 14 do not interfere with the bottom panel 21
- the notches 31 do not necessarily extend through the entire thickness of the pad 30.
- This design of the primary insulating element 7 has several advantages. Thanks to the continuous structure of the bottom panel 21, which can be made in one piece, the body 20 has greater strength, equal dimensions, than crates of the prior art. Internal partitions 25 which are not provided with notches are less likely to crack. With equal strength, they can therefore be made with a lower thickness than in cases of the prior art.
- notch 31 in block 30 can be implemented very easily at any desired location.

- the primary waterproof membrane 9 can be fixed in grooves 32 of the cover panel 22, according to the known technique.
- the grooves 32 of the primary insulating elements 7 may or may not be aligned with the grooves 12 of the secondary insulating elements 3.
- FIG. 2 shows grooves 12 and 32 having an L-shaped section intended to accommodate welding supports which also have an L-shaped cross section.
- welding supports having a J-shaped section, which are compatible with lids less thick.
- the primary insulating element 7 described above has the advantage of being able to be laid in a single step by pre-assembling the insulating pad 30 to the box 20.
- the insulating pad 30 and the box 20 are supplied. and laid separately.
- the insulating pad 30 is held in position within the tank wall under the effect of the clamping exerted by the primary retaining members 8 on the box 20 in the direction of the secondary membrane 5.
- Welding supports housed in the grooves 31 and the adjacent elements also contribute to block laterally the insulating pad 30 in this case.
- a slip layer not shown may be interposed between the latter and the secondary membrane 5 to limit abrasion.
- the technique described above for producing a sealed and insulated tank wall can be used in various types of tanks, for example to form an LNG tank in a land installation or in a floating structure such as a LNG tank or other.
- a cutaway view of a LNG tank 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 sealed barrier intended to be in contact with the LNG contained in the tank, a secondary sealed barrier arranged between the primary watertight barrier and the double hull 72 of the ship, and two insulating barriers respectively arranged between the primary watertight barrier and the secondary watertight barrier and between the secondary watertight barrier and the double hull 72.
- loading / unloading lines 73 arranged on the upper deck of the ship can be connected, by means of appropriate connectors, to a marine or port terminal to transfer a cargo of LNG from or to the tank 71.
- FIG. 3 represents an example of a marine terminal comprising a loading and unloading station 75, an underwater pipe 76 and an onshore installation 77.
- the loading and unloading station 75 is a fixed off-shore installation comprising an arm mobile 74 and a tower 78 which supports the movable arm 74.
- the movable arm 74 carries a bundle of insulated flexible pipes 79 that can connect to the loading / unloading pipes 73.
- the movable arm 74 can be adapted to all gauges of LNG carriers .
- a link pipe (not shown) extends inside the tower 78.
- the loading and unloading station 75 enables the loading and unloading of the LNG tank 70 from or to the shore facility 77.
- the underwater line 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the onshore installation 77 over a large distance, for example 5 km, which makes it possible to keep the tanker vessel 70 at great distance from the coast during the loading and unloading operations.
- pumps on board the ship 70 and / or pumps equipping the shore installation 77 and / or pumps equipping the loading and unloading station 75 are used.
- the invention has been described in connection with a particular embodiment, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
