The sealed membranes are connected to the coupler by means of composite beams fixed on an inner face of insulating boxes forming the thermally insulating barriers. summary

Detailed scripting of embodiments
    The figures are described below in the. frame of a carrier structure formed by the inner walls of a double tank of a vessel for the transport of liquefied gas. Such a carrier structure has a polyhedral geometry, for example of prismatic shape. FIG. 1 illustrates such a carrying structure in which longitudinal walls 1 of the carrying structure extend parallel to the longitudinal direction of the ship and. form a polygonal section in a plane perpendicular to the longitudinal direction of the ship. The longitudinal walls 1 meet at longitudinal edges 2, which form for example angles of the order of 1 * 35 ° in an octagonal geometry. The general structure of such polyhedral vessels is described, for example, with reference to FIG. 1 of document FR3008765.
    The longitudinal walls 1 are interrupted in the longitudinal direction of the ship by transverse bearing walls 3 which are perpendicular to the longitudinal direction of the ship. The longitudinal walls 1 and the transverse walls 3 meet at the edges 4 front and rear.
    Each wall 1, 3 of the supporting structure carries a respective tank wall. Each of the tank walls is composed of at least one thermally insulating barrier carrying a sealing membrane in contact with a fluid stored in the tank, such as liquefied petroleum gas comprising butane, propane, propene or the like. having an equilibrium temperature of between -50 ° C and 0 ° C.
    By convention, the adjective "upper" applied to an element of the vessel designates the portion of this element oriented towards the interior of the vessel and the adjective "inferior" designates the portion of this element oriented towards the outside of the vessel. regardless of the orientation of the vessel wall with respect to the earth's gravity field. Similarly, the term "above" designates a position located closer to the inside of the tank and the term "below" a position located closer to the supporting structure 1, whatever the orientation of the wall of vessel relative to the earth's gravity field.
    FIG. 2 illustrates a vessel angle at the longitudinal edge 4 between one of the longitudinal walls 1 and one of the transverse walls 3 of the supporting structure respectively carrying a longitudinal vessel wall 5 and a transverse vessel wall. 6. The longitudinal vessel wall 5 and the transverse vessel wall 6 meet at an angle structure 7 of the vessel forming an angle of the order of 90 °. Since the longitudinal vessel wall 5 and the transverse vessel wall 6 have a similar structure, only the longitudinal vessel wall 5 is described hereinafter. The description of the longitudinal vessel wall 5 is correspondingly applied to the transverse vessel wall 6.
    The thermally insulating barrier of the longitudinal vessel wall 5 consists of a plurality of heat-insulating elements anchored on any longitudinal supporting wall 1. These heat-insulating elements together form a flat surface on which is anchored the sealing membrane of the longitudinal tank 5. These heat-insulating elements more particularly comprise a plurality of heat insulating elements 8 juxtaposed in a regular rectangular mesh. The thermally insulating barrier of the longitudinal vessel wall 5 also comprises a row of edge insulating element 9 described hereinafter with reference to FIG. 4 arranged along the edge 4. The heat insulating elements 8, 9 are anchored on the carrying structure by any suitable means, for example by means of anchoring members 10 as described with reference to FIG. 4. The heat-insulating elements 8, 9 rest on the longitudinal bearing wall by means of cords mastic (not shown) forming straight or wavy parallel lines. An interspace 11 separates the heat-insulating edge elements vis-à-vis the row of heat insulating elements 9. The interspace 11 of two tank walls forming an edge of the tank are aligned.
    The sealing membrane of the longitudinal vessel wall 5 consists of a plurality of metal plates 12 juxtaposed to each other with overlap. These metal plates 12 are preferably of rectangular shape. The metal plates 12 are welded together to seal the sealing membrane.
    In order to allow the deformation of the sealing membrane in response to the various stresses to which the vessel is subjected, in particular in response to the thermal contraction resulting from the loading of liquefied gas into the vessel, the metal plates 12 comprise a plurality of corrugations 13 oriented towards the inside of the tank. More particularly, the sealing membrane of the longitudinal vessel wall 5 comprises a first series of corrugations 13 and a second series of corrugations 13 forming a regular rectangular pattern. As illustrated in FIG. 2, the first corrugation series 13 is parallel to the edge 4 and the second corrugation series 13 is perpendicular to the edge 4. Preferably, the corrugations 13 develop parallel to the edges of the plates. rectangular metal. In a preferred embodiment illustrated in FIG. 2, the corrugations 13 are situated in line with the spacer spaces 11. Such a preferred embodiment thus does not require a cover plate at the intermediate spaces 1, in order to produce a flat support. for metal plates. The distance between two successive corrugations 13 of a series of corrugations is for example of the order of 600 mm.
    To ensure the continuity of the insulating barrier 2 at the angle structure 7, angle metal plates 15 are welded disposed on the perpendicular edge heat insulating elements 9. These angle metal plates 15 comprise two flat portions 16 located in the planes of the sealed membrane of each tank wall 5 and 6 respectively.
    FIG. 3 is an exploded perspective detail view of an edge insulating element 9 of FIG. 2. The edge insulating element 9 comprises a bottom panel 17, side panels 18 and a cover panel 19. All these panels 17, 18, 19 are of rectangular shape and delimit an internal space of the insulating element of border 9. The bottom panel 17 and the cover panel 19 develop parallel to each other and, as illustrated in Figure 2, parallel to the supporting wall on which they are anchored. The side panels 18 develop perpendicularly to the bottom panel 17. The side panels 18 connect the bottom panel 17 and the cover panel 19 over the entire periphery of the edge insulating member 9. Carrying struts 20 are arranged between the bottom panel 17 and the cover panel 19 in the inner space of the boundary insulating member 9. These carrier struts 20 develop parallel to longitudinal side panels 21. Transverse side panels 22 extending perpendicularly longitudinal side panels 21 have orifices 23. These through holes 23 are intended to allow the circulation of inert gas in the thermally insulating barrier. The panels and carrier struts together form a box in which a heat-insulating gasket 24 is split. This water-repellent gasket 24 is preferably non-structural, for example pearlite or glass wool.
    The bottom panel 17 has longitudinal flanges 25 protruding from it.The longitudinal side panels 21. The bottom panel 17 also has a transverse flange 26 protruding from one of the transverse side panels 22. Cleats 27 are worn on rebound 25, 26 of the bottom panel 17. In the example illustrated in Figure 4, each end of the longitudinal flanges 25 carries a respective cleat 27 and a central portion of the transverse flange 26 carries a cleat 27. In a variant illustrated on the 3, the cleat 27 carried by the transverse flange 26 develops over the entire width of the insulating edge element 9.
    The cover panel 19 has on an upper face opposite to the heat-insulating lining 24 a transverse recess 28. This transverse recess 28 is situated in line with the transverse side panel 22 from which the transverse flange 26 of the bottom panel 17 projects. transverse recess 28 has a notch 29 located at the right of the cleat 27 carried by the transverse flange 26. Many methods can be used to make the cover panel 19. In the embodiment iHustré in Figure 4, two plywood plates having different dimensions are superimposed to form the cover panel 19 having the transverse recess 28. In a non-illustrated embodiment, the cover panel is formed by a plywood plate in which a counterbore is formed to form the transverse recess. .
    The upper face of the cover panel 19 further includes a transverse counterbore 29 and a longitudinal counterbore 30. The transverse counterbore 29 develops in a direction parallel to the width of the cover panel 19 over the entire width of the cover panel 19. The The transverse counterbore 29 is located near the transverse side of the cover panel 17 opposite the transverse flange 26. The longitudinal counterbore 30 develops in a direction parallel to the length of the cover panel 19 over the entire length of the cover panel 19. Preferably , this longitudinal counterbore 30 is centered on the width of the cover panel 19. Typically, in the embodiment illustrated in FIG. 3, the longitudinal countersink 30 is situated in the extension of the notch 29.
    A longitudinal anchoring strip 31 is housed in the longitudinal counterbore 30. This longitudinal anchoring strip 31 has a length less than the length of the cover panel 19. A thermal protection 54 (illustrated in FIG. 2) is housed in the portion of the longitudinal counterbore 30 not comprising the longitudinal anchoring strip 31.
    Likewise, a transverse anchoring strip 32 is housed in the transverse counterbore 29 of the cover panel 19. However, this transverse anchoring strip 32 develops over the entire width of the cover panel 19. Each end of the cover strip 32 transverse anchor 32 has a tab 33. This tab 33 projects from a respective longitudinal side of the cover panel 19.
    Similarly to the insulating edge elements 9, each current heat insulating element 8 comprises on an upper face two perpendicular anchoring strips 14 housed in respective countersinks. The anchor strips 14 are preferably arranged parallel to the corrugations 13. The anchor strips 14 develop on a central portion of the counterbores in which they are housed. Thermal protections 54 are housed in the ends of the countersinks.
    The metal plates 12, 15 of the sealed membrane are welded to the anchor strips 14, 31, 32 on which they rest. The thermal protections 54 prevent the degradation of the insulating elements 8, 9 during the soldering of the metal plates 12, 15. The welding of the metal plates 12, 15 on the anchor strips 14, 31, 32 makes it possible to retain the waterproof membrane on the insulating barrier, but causes the transmission of tensile forces by the metal plates 12, 15 to the anchor strips 14, 31, 32 on which they are welded.
    The tab 33 has a spacing portion 34 extending from the cover panel 19 in the extension of the transverse counterbore 29. This tab further comprises a coupling portion 35 developing from an end of the spacer portion 34 opposite the cover panel 19. The coupling portion 35 develops towards the bottom panel 17. The coupling portion 35 has a slot 52 facing the transverse side of the cover panel 19 having the recess 29.
    The anchoring strips 29, 30 are fixed on the cover panel 19 by any suitable means, for example by riveting. The attachment of the transverse anchoring strip 32 is made so as to have a play in a longitudinal direction of the cover panel 19, for example of the order of one to a few tenths of a millimeter. Typically, in the case of a fastening by riveting, the orifices (not shown) of the cover panel 19 traversed by the fastening rivets of the transverse anchoring strip 32 have a longitudinal dimension greater than the thickness of the rivet. Similarly, the transverse anchoring strip 32 is housed in the transverse counterbore 29 with a clearance. Such clearances allow the transmission of tensile forces generated in the longitudinal direction of the cover panel 19 by the sealed membrane welded onto the strips. anchoring 31, 32, without these efforts being substantially transmitted to the cover panel 19.
    FIG. 4 is a detail view illustrating a longitudinal edge heat-insulating element 36 and a transverse edge heat-insulating element 37 belonging to the longitudinal vessel wall 5 and the transverse vessel wall 6. The longitudinal edge heat-insulating element 36 and the transverse edge heat-insulating element 37 together form the angle structure 7. The transverse edge of the longitudinal edge heat-insulating element 36 not having the recess 29 and the transverse edge of the transverse edge heat-insulating element 37 not having the recess 29 are contiguous. Since the longitudinal edge heat-insulating element 36 has a structure similar to the structure of the transverse edge heat-insulating member 37, only the longitudinal edge member 36 illustrated in FIG. 4 is described hereinafter. The description of this longitudinal edge heat insulating element 36 applies by analogy to the transverse edge heat-insulating element 37.
    The anchoring members 10 illustrated in FIG. 4 each comprise a stud 38 welded to the longitudinal bearing wall 1. Each stud 38 is developed perpendicularly to the longitudinal bearing wall 1. One end of the studs opposite to the longitudinal bearing wall 1 comprises a thread. A square support plate 39 has a central orifice (not illustrated) through which the stud 38 passes. A nut 40 is mounted on the threaded end of the stud 38. The support plate 39 of each stud 38 is thus maintained. supported by said nut 40 against an upper face of a respective batten 27 carried by a flange 25, 26 corresponding to the bottom panel 17. In a variant not shown, the support plate rests directly on the edge of the bottom panel of the heat insulating element.
    As illustrated in FIG. 2, such anchoring members 10 are also arranged at the corners of each current heat-insulating element 8. The side walls of each current heat-insulating element 8 comprise a flange. A batten 27 is disposed on each end of said flange. Each cleat 27 of the. current heat insulating elements 8 cooperates with a respective anchoring member 10, the same bearing member 10 cooperating with the cleats 27 of a plurality of adjacent heat insulating elements 8. The angles of the adjacent heat insulating elements 8 comprise a clearance jointly forming a chimney in line with a corresponding fixing member 10. This chimney makes it possible to screw the nut 40 onto the bolt of the fixing lug 10. This chimney is filled with a heat-insulating lining 4 and covered with a shutter plate 42 so as to form a flat surface with the panels. of lids of the heat-insulating elements.
    In the embodiment illustrated in FIG. 2, each current insulating element 8 has a width, taken parallel to the edge 4, twice the width of the heat insulating elements 9. The current heat-insulating elements 8 and the heat-insulating elements curbs 9 are arranged so that the corners of two adjacent heat insulating elements 8 are located mid-width of a heat insulating edge element 9, at the right of the transverse flange 26 of a respective edge insulating element 9. The anchoring member 10 associated with said corners of the current heat-insulating elements 8 thus cooperates with both the cleats 27 of said current heat-insulating elements 8 and with the cleat 27 carried by the transverse flange 26. The notch 29 of the heat-insulating element edge 9 allows the passage of the tooling required to screw the nut of said anchor member 10
    In a non-illustrated embodiment, the current heat insulating elements and the heat insulating elements of borders have the same width but are offset with respect to each other along a direction parallel to the edge. Thus, the corners of two adjacent heat insulating elements are located mid-width of a heat insulating edge element and the right of the transverse edge of said insulating edge element.
    Furthermore, the current heat insulating elements 8 located vis-à-vis the insulating elements. curb 9- comprise a recess similar to the recess 28 of said insulating edge member 9 vis-à-vis said step 29 of the insulating element of edge 9. Covering strips 53 are housed jointly in the recesses of the current heat insulating elements 8 and heat-insulating elements of edge 9 vis-à-vis to cover a space between said insulating elements 8 and 9. This space is filled with heat-insulating lining such as glass wool. Such cover strips are flush with the top face of the cover panels of the insulating elements 8 and 9 to provide a continuous flat surface to the waterproof membrane. Moreover, such cover strips 53 make it possible to catch up with constructional games that may appear during construction of the tank.
    With reference to FIG. 2, in order to avoid a degradation of the sealing characteristics of the tank, the membranes are anchored to the bearing structure by means of anchoring rods 43 in the zone where the walls of the tank form the angle structure 7 of the tank. More specifically, each edge insulating element 9 is coupled on either side of the lateral side panels 21 to an anchor rod 43. More particularly, each anchor tab 33 is coupled to a respective anchor rod 43 . The cooperation between the anchoring tabs 33 and the anchoring rods 43 is similar for all the anchoring rods 43 of the tank, only the anchoring rod 43 anchored to the anchoring tab 33 illustrated on the Figure 4 is described below, this description applying by analogy to all the anchor rods 43 of the tank.
    The anchor rod 43 is anchored to the transverse bearing wall 3. This anchor rod 43 develops from the transverse bearing wall 3 perpendicularly to the transverse bearing wall 3. The anchor rod 43 is thus housed in the space insert 11 between two transverse heat insulating elements at its end anchored to the transverse bearing wall 3 and in the intermediate space 11 between two longitudinal edge insulating elements.
    One end 44 of the anchor rod 43 opposite to the transverse bearing wall 3 is coupled to a first leg 33 of the transverse anchoring strip 32. The stresses to which the sealed membrane is fastened on the transverse anchoring strip 32, by example linked to a loading of liquefied gas in the tank, thus generate forces transmitted to the transverse bearing wall 3 thus improving the resistance of the tank. In addition, these forces pass through the waterproof membrane, the transverse anchoring strip 32 and the anchor rod 43 without exerting any significant effort on the cover panel 19, the edge heat-insulating element 9 not thus undergoing any stress. in negligible shear.
    FIG. 5 illustrates the cooperation between the anchoring rod 43 and, on the one hand, the transverse bearing wall 3 and, on the other hand, the tab 33 of the transverse anchoring strip 32 of the longitudinal edge heat-insulating element 36 .
    The anchor rod 43 has at its end anchored to the transverse carrier wall 3 a thread. This threaded end is housed in a hollow cylindrical base. This hollow cylindrical base comprises a flat base 45 welded to the transverse bearing wall 3, a cylindrical wall 46 developing perpendicular to the transverse bearing wall 3 towards the inside of the tank and a cover wall 47 parallel to the transverse bearing wall 3 The cover wall 47 has an orifice through which the anchor rod 43 passes. The cylindrical wall 46 has an internal face of complementary shape to a nut 48 housed in the hollow cylindrical base. This complementarity of the shapes between the nut 48 and the inner face of the cylindrical wall 46 blocks the nut 48 in rotation in the hollow cylindrical base. Furthermore, the nut 48 has dimensions greater than the dimensions of the through orifice of the cover wall 47, thus locking the nut 48 in the hollow cylindrical base. The threaded end of the anchor rod 43 is screwed onto the nut 48 thus ensuring anchoring of the anchor rod 43 on the transverse bearing wall 3. The end 44 of the anchor rod 43 comprises a hook. This hook has a "U" profile, a base 49 of which is traversed by the anchoring rod 43 as illustrated in FIG. 6. Branches 50 of the hook develop from the base 49 in the direction of the transverse bearing wall 3 perpendicular to the base 49. A nut 51 is screwed onto the end 44 to block the hook moving along the anchor rod 43. A first leg 50 of the hook is engaged in the slot 52 of the anchor 33 Typically, the coupling portion 35 of the lug 33 is interposed between the first leg 49 and the anchor rod 43 and the base 49 is coupled in tension to the slot 52 of the coupling portion 35 in the illustrated embodiment. in Figure 5, a washer is interposed between the nut 51 and the base 49.
    An anchor rod 43 anchored to the longitudinal bearing wall 1 is coupled to a tab 33 of a transverse edge heat-insulating element 37 in a similar manner to the anchoring rod 43 anchored to the transverse bearing wall 3 and coupled to an element insulating longitudinal edge 36 as described above.
    An anchor rod 43 is anchored to the carrier wall at each intermediate space 11 of the tank so that a first leg 50 of the hook of the anchor rod is coupled to a first leg 33 projecting from a first element. insulation lagging 9 in said spacer space 11 and a second leg 50 of the hook of the anchor rod 43 is coupled to a second tab 33 projecting from a second insulating element of edge 9 in said interspace 11. The first insulation element 9 and the second thermal insulating element 9 are adjacent and delimit the interspace 11.
    In addition, the spaces 55 located between the heat insulating elements 9 and the supporting walls 1 and 3 vis-à-vis are advantageously filled with heat insulating material such as glass wool.
    Figures 7 to 9 show a tank ridge between two longitudinal tank walls 5 forming an angle of the order of 135 °. Such a tank ridge has a structure similar to the tubular angle structure 7 forming an angle of 90 ° as described with reference to FIGS. 2 to 6. The same reference numerals are used for elements having the same structure and / or the same function.
    At an edge 2 forming an angle of 135e, the anchor rods 43 develop parallel to the membrane of the longitudinal vessel wall 5 to which they are coupled. Thus, the anchor rods 43 form an angle of the order of 135 ° with the longitudinal bearing wall 43 to which they are fixed, as can be seen in FIGS. 7 and 8. Moreover, the orifice of the The hollow cylindrical base traversed by the anchor rod 43 is located jointly on the cover wall 47 and on the cylindrical wall 46 of the cylindrical base.
    In this embodiment, the orifice of the hollow cylindrical base allows an angular displacement of the anchor rod 43 relative to the hollow cylindrical base around an axis parallel to the edge 2 of the supporting structure .
    The technique described above for producing a tank having a single sealed membrane can be used in different types of tanks, for example to form a double membrane tank for liquefied natural gas (LNG) in a land installation or in a floating structure as a LNG tanker or other. In this context, it may be considered that the diaphragm qtanche illustrated in the previous figures is a secondary waterproof membrane, and a primary insulating barrier and a primary waterproof membrane, not shown, must be added to this secondary waterproof membrane. In this way, this technique can also be applied to tanks having a plurality of thermally insulating barrier and superimposed waterproof membranes.
    Figure 10 shows a schematic top view of a tank wall at an edge according to an alternative embodiment. In this figure, the same elements or elements fulfilling the same function carry reference numerals increased by 100 with respect to the reference numbers of the preceding figures.
    In the variant illustrated in FIG. 10, the edge heat-insulating elements 109 have a width close to the width of the current heat-insulating elements 108. The width of the current heat-insulating elements 108 is, for example, about 1200 mm, and the width of the heat-insulating elements of border 109 of the order of 1160mm. In this variant, the corrugations (not illustrated) of the metal plates (not shown) are no longer placed at the right of the spacer spaces 111 but on the cover panels 119 of the heat insulating elements 109. Moreover, the metal plates (not illustrated ) are welded on the anchoring strips 132 in a discontinuous manner and only at a central portion 156 of the anchoring strip 132. This discontinuous welding of the metal plates allows the corrugations to work in extension in order to make up for the deformations of the waterproof membrane. The heat insulating elements 109 are centered on the current heat insulating elements 108. Similarly, the anchoring strips 114 and 131 are arranged coaxially in a direction perpendicular to the edge 104.
    Referring to Figure 11, 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 liquefied gas contained in the tank, a secondary sealed barrier arranged between the primary waterproof barrier and the double hull 72 of the ship, and two insulating barriers arranged respectively between the primary watertight barrier and the secondary watertight barrier and between the secondary watertight barrier and the double hull 72. In a simplified version, the vessel comprises a single hull.
    In a manner known per se, 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 for transferring a cargo of liquefied gas from or to the tank 71.
    FIG. 11 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 connection 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. liquefied gas storage tanks 80 and connecting lines 81 connected by the underwater line 76 to the loading or unloading station 75. 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.
    In order to generate the pressure necessary for the transfer of the liquefied gas, 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.
