    [0001] TECHNICAL FIELD The invention relates to the field of sealed and thermally insulating tanks, with membranes, for storing and / or transporting fluid, such as a cryogenic fluid.
    [0002] Watertight and thermally insulating membrane tanks are used in particular for the storage of liquefied natural gas (LNG), which is stored at atmospheric pressure at about -162 ° C. These tanks can be installed on the ground or on a floating structure. In the case of a floating structure, the tank may be intended for the transport of liquefied natural gas or to receive liquefied natural gas used as fuel for the propulsion of the floating structure. BACKGROUND ART In the prior art, sealed and thermally insulating tanks are known for the storage of liquefied natural gas, integrated in a supporting structure, such as the double hull of a ship intended for the transport of natural gas. liquefied. Generally, such tanks comprise a multilayer structure successively presenting, in the direction of the thickness, from the outside to the inside of the tank, a secondary thermal insulation barrier retained to the supporting structure, a waterproofing membrane. secondary shield resting against the secondary thermal insulation barrier, a primary thermal insulation barrier resting against the secondary sealing membrane and a primary sealing membrane intended to be in contact with the liquefied natural gas contained in the tank. In FR 2 996 520, there is described a secondary sealing membrane consisting of a plurality of metal sheets having corrugations projecting outwardly of the tank and thus allowing the secondary sealing membrane to deform under the effect of thermal and mechanical stresses generated by the fluid stored in the tank. The secondary thermal insulation barrier is composed of a plurality of insulating panels juxtaposed against the supporting structure. The insulating panels of the secondary thermal insulation barrier are separated by interstices inside which are inserted the corrugations of the metal sheets of the secondary waterproofing membrane. Furthermore, the metal sheets of the secondary waterproofing membrane are welded to metal plates fixed on the inner face of the insulating blocks of the secondary thermal insulation barrier so as to anchor the secondary waterproofing membrane on the barrier. secondary thermal insulation. When the tank is cold, that is to say when the tank is filled with liquefied natural gas, the insulating panels of the secondary thermal insulation barrier tend to shrink in such a way that they spread apart from each other. The insulating panels may also deviate from each other due to the deformation of the double hull of the ship. However, the spacing of the insulating panels of the secondary thermal insulation barrier leads to significant stress on the secondary waterproofing membrane. In addition, this separation urges all the more the secondary waterproofing membrane that it is sandwiched between the insulating panels of the secondary thermal insulation barrier and those of the primary thermal insulation barrier and that the separation of the insulating panels therefore generates friction of the secondary waterproofing membrane against the insulating panels of the primary and secondary thermal insulation barriers. It is certainly provided in a document WO2013004943, a secondary waterproofing membrane, consisting of a plurality of corrugated metal sheets having corrugations protruding outwardly of the vessel, which is attached to couplers directly connected to the structure carrier. Thus, since such a secondary waterproofing membrane is not directly attached to the insulating panels of the secondary thermally insulating barrier, it is not mechanically impacted during mutual separation of the insulating panels. However, such a design is not satisfactory either. Indeed, such attachment of the secondary sealing membrane on the couplers ensures only point connections of the secondary sealing membrane so that it is not solicited homogeneously. Furthermore, the secondary waterproofing membrane being sandwiched between the insulating panels of the secondary thermal insulation barrier and those of the primary thermal insulation barrier, the mutual separation of the insulating panels of the thermal insulation barrier secondary still leads to a mechanical stress of the secondary waterproofing membrane given the friction exerted between it and the insulating panels of the secondary thermal insulation barrier.

DETAILED DESCRIPTION OF EMBODIMENTS By convention, the terms "external" and "internal" are used to define the relative position of one element relative to another, with reference to the interior and exterior of the vessel. In Figures 1 and 2, there is shown the multilayer structure of a sealed and thermally insulating tank for storing a fluid. Each wall of the tank comprises, from the outside to the inside of the tank, a secondary thermal insulation barrier 1 comprising insulating panels 2 juxtaposed and anchored to a supporting structure 3 by secondary retaining members 8, a membrane secondary sealing 4 scope; DAI- the insulating panels 2 of the secondary thermal insulation barrier 1, a primary thermal insulation barrier 5 comprising insulating panels 6 juxtaposed and anchored to the insulating panels 2 of the thermal insulation barrier secondary 1 by primary retaining members 19 and a primary sealing membrane 7, carried by the insulating panels 6 of the primary thermal insulation barrier 5 and intended to be in contact with the cryogenic fluid contained in the tank. The supporting structure 3 can in particular be a self-supporting metal sheet or, more generally, any type of rigid partition having suitable mechanical properties. The supporting structure 3 can in particular be formed by the hull or the double hull of a ship. The supporting structure 3 comprises a plurality of walls defining the general shape of the tank, usually a polyhedral shape.
    [0005] The secondary thermal insulation barrier 1 comprises a plurality of insulating panels 2 anchored on the supporting structure 3 by means of resin beads, not shown, and / or studs 8 welded to the supporting structure 3. The resin beads must be sufficiently adhesive when they alone insure the anchoring of the insulating panels 2 but are not necessarily adhesive when the insulating panels are anchored by means of the studs 8. The insulating panels 2 have substantially a rectangular parallelepiped shape.
    [0006] As illustrated in particular in Figures 3, 5 and 6, the insulating panels 2 each comprise a layer of insulating polymer foam 9 sandwiched between an inner rigid plate 10 and an outer rigid plate 11. The rigid plates, internal 10 and external 11 are, for example, plywood boards bonded to said insulating polymer foam layer 9. The insulating polymer foam may in particular be a polyurethane-based foam. The polymeric foam is advantageously reinforced by glass fibers contributing to reducing its thermal contraction. The insulating panels 2 are juxtaposed in parallel rows and separated from each other by interstices 12 ensuring a functional assembly play. The interstices 12 are filled with a heat insulating lining 13, shown in Figures 2 and 8, such as glass wool, rock wool or soft synthetic foam open cell for example. The heat-insulating lining 13 is advantageously made of a porous material so as to provide gas flow spaces in the interstices 12 between the insulating panels 2. Such gas flow spaces are advantageously used in order to allow a flow of gas inert, such as nitrogen, within the secondary thermal insulation barrier 1 so as to maintain it under an inert atmosphere and thus prevent combustible gas from being in an explosive concentration range and / or to place the secondary thermal insulation barrier 1 in depression to increase its insulating power. This flow of gas is also important to facilitate the detection of possible fuel gas leaks. The interstices 12 have, for example, a width of the order of 30 MM.
    [0007] An inner plate 10 according to one embodiment is shown in detail in Figures 3 and 4. The inner plate 10 has two series of grooves 14, 15, perpendicular to each other, so as to form a network of grooves. Each of the series of grooves 14, 15 is parallel to two opposite sides of the insulating panels 2. The grooves 14, 15 are intended for receiving corrugations, protruding towards the outside of the tank, formed on the metal sheets of the secondary sealing barrier 4. In the embodiment shown, the inner plate 10 has three grooves 14 extending in the longitudinal direction of the insulating panel 2 and nine grooves 15 extending in the transverse direction of the insulating panel 2.
    [0008] The grooves 14, 15 completely cross the thickness of the inner plate 10 and thus open at the level of the insulating polymeric foam layer 9. Moreover, the insulating panels 2 comprise in the zones of intersection between the grooves 14, 15, release openings 16 formed in the layer of insulating polymer foam 9. The clearance orifices 16 allow the housing of the node zones formed at the intersections between the corrugations of the metal sheets of the secondary sealing barrier 4. These nodes zones, described in more detail later, have a vertex projecting outwardly of the vessel.
    [0009] Furthermore, the inner plate 10 is equipped with metal plates 17, 18 for anchoring the edge of the corrugated metal sheets of the secondary sealing membrane 4 on the insulating panels 2. The metal plates 17, 18 extend in two directions. perpendicular directions which are each parallel to two opposite sides of the insulating panels 2. The metal plates 17, 18 are fixed to the inner plate 10 of the insulating panel 2, by screws, rivets or staples, for example. The metal plates 17, 18 are placed in recesses formed in the inner plate 10 so that the inner surface of the metal plates 17, 18 is flush with the inner surface of the inner plate 10.
    [0010] The inner plate 10 is also equipped with threaded studs 19 protruding towards the inside of the tank, and intended to ensure the fixing of the primary thermal insulation barrier 5 on the insulating panels 2 of the secondary thermal insulation barrier 1 The metal studs 19 pass through orifices formed in the metal plates 17.
    [0011] Moreover, in order to ensure the fixing of the insulating panels 2 to the studs 8 fixed to the supporting structure 3, the insulating panels 2 are provided with cylindrical wells 20, shown in FIGS. 3 and 4, passing through the insulating panels 2 over their whole length. thickness. The cylindrical wells 20 have a sectional change, not illustrated, defining bearing surfaces for nuts cooperating with the threaded ends of the studs 8. According to one embodiment, the sectional change of the cylindrical wells 20 is between the plate 11 and the insulating polymer foam layer 9. Thus, the nuts cooperating with the threaded ends of the studs 8 are in abutment against a bearing surface formed by the outer plate 11. In other words, the insulating panels are retained on the supporting structure via their outer plate 11 Furthermore, the inner plate 10 has along its edges, in each gap between two successive grooves 14, 15, a recess 21 for receiving a bridging element. Such bridging elements are in particular represented in FIGS. 7, 8 and 9. In these figures, the bridging elements are bridging plates 22 which are each arranged astride between two adjacent insulating panels 2, straddling the gap 12 between the insulating panels 2. Each bridging plate 22 is fixed against each of the two adjacent insulating panels 2 so as to oppose their mutual spacing. The bridging plates 22 have a rectangular parallelepipedal shape and consist for example of a plywood plate. The outer face of the bridging plates 22 is fixed against the bottom of the recesses 21. The depth of the recesses 21 is substantially equal to the thickness of the bridging plates 22 so that the inner face of the bridging plates 22 reaches substantially at the level of the bridging plates 22. other flat areas of the inner plate 10 of the insulation board. Thus, the bridging plates 22 are able to ensure continuity in the carrying of the secondary sealing membrane 4. In order to ensure a good distribution of the connection forces between the adjacent panels, a plurality of bridging plates 22 extends along each edge of the inner plate 10 insulating panels 2, a bridge plate 22 being disposed in each gap between two adjacent grooves 14, 15 of a series of parallel grooves. Advantageously, the bridging plates 22 extend over substantially the entire length of the gap between two adjacent grooves 14, 15. In addition, the recesses 21 have a transverse dimension such that the edges of the bridging plates 22 come into contact with one another. abutment against the edge of the recess 21 so as to facilitate the positioning of the bridging plates 22 against the inner surface of the insulating panels 2. The bridging plates 22 may be fixed against the inner plate 10 of the insulating panels 2 by any appropriate means. However, it has been found that the combination of the application of an adhesive between the outer face of the bridging plates 22 and the inner plate 10 of the insulating panels 2 and the use of mechanical fasteners, such as staples , allowing pressurization of the bridging plates 22 against the insulating panels 2, was particularly advantageous. In other embodiments, shown in Figures 25 and 26, the bridging plates 22 are provided with grooves 50 receiving corrugations 25, 26 corrugated metal sheets 24. In such an embodiment, a bridging plate 22 may extend over the entire length of an edge of the inner surface of an insulating panel 2 and have a series of grooves extending in the extension of the series of grooves 14, 15 formed in the inner plates 10 of the panels adjacent 2. Furthermore, the bridging plates 22 may also be equipped with a groove 50 extending along the gap between the two adjacent insulating panels 2 they overlap.
    [0012] As shown in FIG. 8, the zones of intersection between the inter-panel gaps 12 are covered by a bridge plate 23 disposed against the four adjacent corners of the inner plates 10 of four adjacent insulating panels 2. Such a bridge plate 23 has for example a cross shape or a square shape.
    [0013] Furthermore, according to one embodiment, the bridging plates 22 lying in the extension of the directions of the metal plates 17, 18 fixed on the insulating panels 2 are equipped with metal plates, fixed against the internal face of said bridging plates 22 and intended for anchoring the secondary sealing membrane 4. Such an arrangement makes it possible to ensure the continuity of the anchoring of the secondary sealing membrane 4 on the secondary thermal insulation barrier 1. In relation to the figures 10 and 11, it is observed that the secondary sealing barrier comprises a plurality of corrugated metal sheets 24 each having a substantially rectangular shape. The corrugated metal sheets 24 are arranged offset from the insulating panels 2 of the secondary thermal insulation barrier 1 so that each of said corrugated metal sheets 24 extends jointly on four adjacent insulating panels 2.
    [0014] Each corrugated metal sheet 24 has a first series of parallel corrugations 25 extending in a first direction and a second series of parallel corrugations 26 extending in a second direction. The directions of the series of corrugations 25, 26 are perpendicular. Each of the series of corrugations 25, 26 is parallel to two opposite edges of the corrugated metal sheet 24. The corrugations 25, 26 protrude towards the outside of the vessel, that is to say in the direction of the supporting structure 3. The corrugated metal sheet 24 has between the corrugations 25, 26, a plurality of planar surfaces. At each crossing between two corrugations 25, 26, the metal sheet comprises a node zone 27, shown in FIG. 11. The node zone 27 has a central portion having an apex projecting towards the inside of the vessel. Moreover, the central portion is bordered, on the one hand, by a pair of concave corrugations formed in the crest of the corrugation 25 and, on the other hand, by a pair of recesses into which the corrugation 26 penetrates. In the embodiment shown, the corrugations 25, 26 of the first series and the second series have identical heights. However, it is possible to predict that the corrugations 25 of the first series have a height greater than the corrugations 26 of the second series or vice versa. As shown in FIG. 10, the corrugations 25, 26 of corrugated metal sheets 24 are housed in the grooves 14, 15 formed in the inner plate 10 of the insulating panels 2. The adjacent corrugated metal sheets 24 are welded together. The anchoring of the corrugated metal sheets 24 on the metal plates 17, 18 is achieved by pointing welds.
    [0015] The corrugated metal sheets 24 comprise along their longitudinal edges and at their four corners cutouts 28 allowing the passage of the studs 19 for fixing the primary thermal insulation barrier 5 on the secondary thermal insulation barrier 1. The corrugated metal sheets 24 are, for example, made of Invar0: that is to say an alloy of iron and nickel whose coefficient of expansion is typically between 1.2.10-6 and 2.10-6 K- 1, or in an iron alloy with a high manganese content whose expansion coefficient is typically of the order of 7.10-6 K-1. Alternatively, the corrugated metal sheets 24 may also be made of stainless steel or aluminum.
    [0016] As shown in Figure 2, the primary thermal insulation barrier 5 comprises a plurality of insulating panels 6 of substantially rectangular parallelepiped shape. The insulating panels 6 are here offset with respect to the insulating panels 2 of the secondary thermal insulation barrier 1 so that each insulating panel 6 extends over four insulating panels 2 of the secondary thermal insulation barrier 1. A panel 6 is shown in detail in Figure 12. It comprises a structure similar to an insulating panel 2 of the secondary thermal insulation barrier 1, namely a sandwich structure consisting of a layer of insulating polymer foam 29 sandwiched between two rigid plates, for example plywood 30, 31. The inner plate 30 of an insulating panel 6 of the primary thermal insulation barrier 5 is equipped with metal plates 32, 33 for anchoring corrugated metal sheets of the primary sealing membrane 7. The metal plates 32, 33 extend in two perpendicular directions which are each parallel to two opposite edges s insulation board 6. The metal plates 32, 33 are secured in recesses in the inner plate 30 of the insulating panel 5 and fastened thereto by screws, rivets or staples, for example. Furthermore, the inner plate 30 of the insulating panel 6 is provided with a plurality of relaxation slots 34 allowing the primary waterproofing membrane 7 to deform without imposing excessive mechanical stresses on the insulating panels 6. Such slits relaxation of relaxation are in particular described in the document FR 3 001 945. The fixing of an insulating panel 6 of the primary thermal insulation barrier 5 on the studs 19 carried by the secondary thermal insulation barrier 1 can be realized, in a embodiment, as shown in Figure 13. The insulating panel 6 has a plurality of cutouts 35 along its edges and at its corners. The outer plate 30 projects inside the cutouts 35 so as to form a bearing surface. A retaining member 36 has lugs housed inside the cutouts 35 and bearing against the portion of the outer plate 31 projecting inside the cutout 35 so as to sandwich the outer plate 31 between a tab of the retaining member 36 and an insulating panel 2 of the secondary thermal insulation barrier 1. The retaining member 36 has a bore threaded onto a threaded stud 19. Furthermore, a nut 37 cooperates with the thread of the stud threaded 19 so as to ensure the fixing of the retaining member 36. A set of Belleville washers is threaded on the threaded stud 19, between the nut 37 and the retaining member 36. Moreover, as shown in FIG. 14, the primary thermal insulation barrier 5 comprises a plurality of closure plates 38 for completing the bearing surface of the primary waterproofing membrane 7 at the cutouts 35. As illustrated in detail on 13, the size of the cutouts 35 at the inner plate 30 is greater than its dimension at the level of the insulating polymeric foam layer 29 so as to form a counterbore for positioning and retaining the closure plates 38. The closure plates 38 may in particular be fixed against the counterbore by staples. The primary waterproofing membrane 7 is obtained by assembling a plurality of corrugated metal sheets 39, one of which is shown in FIG. 15. Each corrugated metal sheet 39 comprises a first series of parallel corrugations 40, so-called high, s'. extending in a first direction and a second series of parallel corrugations 41, said low, extending in a second direction perpendicular to the first series. The node areas 42 have a structure close to that of the node areas 27 corrugated metal sheets 24 of the secondary sealing membrane 4. The corrugations 40, 41 protrude inwardly of the vessel. The corrugated metal sheets 39 are, for example, made of stainless steel or aluminum. Figures 16 and 17 show a bridging element, according to a second embodiment, extending astride between two insulating panels 2 of the secondary thermal insulation barrier 1. In this embodiment, each bridging element is formed two metal plates 43, 44 which are each retained in a groove 45 formed along an edge of an inner plate 10 of an insulating panel 2. The groove 45 has an inverted T-shape, as shown in FIGS. Figures 16 and 17, or a form of J. One edge of each metal plate 43, 44 is folded and has a flange 46 which is retained inside the groove 45. The two metal plates 43, 44 are fixed to each other in situ after the fixing of the insulating panels 2 against the supporting structure 3. The two metal plates 43, 44 are fixed to one another in a covering area via fasteners, such as rivets 47 The m Embodiment shown in Figures 22, 23 and 24 differs in particular from the embodiment of Figures 16 and 17 by the method of fixing the two metal plates 43, 44 to one another. The two metal plates 43, 44 have crenellated edges 51 which fit one into the other. The crenellated edges 51 are folded so as to constitute hooks in which is inserted a horizontal pin 52. Note also that the groove 45 formed along an edge of an inner plate 10 of an insulating panel 2 and to retain the metal plates 43,44 has a shape of J.
    [0017] Figures 18 and 19 show a bridging element according to a third embodiment. In this embodiment, the bridging elements are metal wires 48 which are taken up on screws 49 which are fixed on the edges of the inner plate 10 of the two adjacent insulating panels 2. The inner plate 10 also has, along its edges, recesses 21 inside which are housed the screws 49 so that the heads of the screws 49 do not protrude beyond the bearing surfaces of the plate 10 and are thus likely to damage the corrugated metal sheets 24 of the secondary sealing membrane 4. Alternatively, the bridging elements consist of flexible elements, such as blades or slats whose ends are attached to screws inserted into the edges of the inner plate of two adjacent insulating panels. In the embodiment shown in FIG. 21, the corrugated metal sheets 24 of the secondary sealing barrier 4 comprise corrugations 53 projecting towards the inside of the tank, contrary to the corrugations of the preceding embodiments. The corrugated metal sheets 24 of the secondary sealing barrier also comprise two series of perpendicular corrugations. As in the previous embodiments, the corrugated metal sheets are fixed on the inner plate of the insulating panels of the secondary sealing membrane by means of metal plates, not shown, extending in two perpendicular directions which are fixed on the internal plate 10 of the insulating panels 2. However, in this embodiment, the outer plate 30 of the insulating panels 6 of the primary thermal insulation barrier 5 have two series of grooves perpendicular to each other so as to form a network of grooves.
    [0018] The grooves 54 are thus intended to receive the undulations 53, projecting towards the inside of the tank, formed on the corrugated metal sheets 24 of the secondary sealing barrier 4. With reference to FIG. of a LNG ship 70 shows a sealed and insulated tank 71 of generally prismatic shape mounted in the double hull 72 of the ship.
