    [0001] TECHNICAL FIELD The invention relates to the field of tanks with sealed and insulating membranes arranged in floating structures, in particular for the storage and / or transport of a cold product, in particular a liquefied gas, for example liquefied natural gas (LNG ) which contains a high methane content and has a liquid state at about -162 ° C at atmospheric pressure. TECHNOLOGICAL BACKGROUND In the technique of membrane tanks, the internal surfaces of a supporting structure such as the inner shell of a double-hulled vessel are lined with a multilayer structure comprising two thin, alternating, two-layer sealing membranes. thermal insulation which serve both to limit the heat flow through the tank wall and to structurally support the sealed membranes.
    [0002] In order to maximize the operating efficiency of such a tank, it is desirable to optimize the useful volume of cargo that can be loaded into the tank and to discharge from the tank. However, the use of an unloading pump drawing the liquid to the top of the tank requires to maintain a certain height of liquid at the bottom of the tank, otherwise the suction member of the pump enters into communication with the gas phase, which defuses and / or degrades the pump. Given the swelling of the cargo by the swell, the necessary liquid height can hardly be minimized. The publication FR-A-2832783 contemplates the production of a sump in the cryogenic insulation of the tank as an expensive and inefficient solution.
    [0003] Publication KR-10-2010-0092748 discloses a sump obtained by producing a concave stepped portion in the bottom wall of a membrane tank. However, this stepped portion presents difficulties of realization in view of the need to deflect the entire multilayer structure of the tank wall in the concave stepped portion.

DETAILED DESCRIPTION OF THE EMBODIMENTS In the description below, several sumps structures that can be used in the bottom wall of an LNG storage and / or transport vessel will be described. The bottom wall designates a wall, preferably generally flat, located in the bottom of the tank relative to the earth's gravity field. The general geometry of the tank can also be of different types.
    [0009] Polyhedral geometries are the most common. A cylindrical, spherical or other geometry is also possible. The walls of the tank are formed by a multilayer structure fixed on load-bearing walls and including two alternating waterproof membranes with two thermally insulating barriers. Since there are many known techniques for making these multilayer structures, the description below will be limited to the sump structure and the wall area in close proximity to the sump structure. Referring to Figure 1, a suction head of a pump shown schematically at the number 1 is received in a sump structure 10 arranged in a vessel wall 2 at the bottom of the tank. The tank wall 2 is mounted on a plane carrying wall 3, made for example of thick steel sheet such as the inner shell of a double-hulled vessel. The tank wall 2 has a multilayer structure successively including a secondary insulating barrier 4 fixed to the carrier wall 3, for example by means of beads of putty 8, a secondary waterproof membrane 5 supported by the secondary insulating barrier 4, an insulating barrier primary 6 covering the secondary waterproof membrane 5 and a primary waterproof membrane 7 supported by the primary insulating barrier 6. At the location of the sump structure 10, the carrier wall 3 30 has a circular opening 9 through which the sump structure 10 is engaged and which allows the sump structure 10 to protrude outside the carrier wall 3 in the thickness direction of the vessel wall 2.
    [0010] A hollow cylindrical bowl 20 is fixed on the carrier wall 3 around the opening 9 and protrudes outwardly from the carrier wall 3 to form an extension structure which provides additional space for accommodating the sump structure 10. More specifically, the hollow cylindrical bowl 20 comprises a cylindrical lateral wall 21, for example circular or other, of which an upper edge is welded to the supporting wall 3 all around the opening 9 and a flat bottom wall 22, for example circular or other, welded to a lower edge of the cylindrical side wall 21 and disposed parallel to the carrier wall 3. The hollow cylindrical bowl 20 may be made of similar materials to the carrier wall 3. To prevent the bowl hollow cylindrical 20 has a tendency to collect liquids accidentally present in the secondary insulating barrier 4, such as water of condensation or water from d At the level of the ballast, it is preferable to provide a flange 26 projecting towards the inside of the tank 15 on the supporting wall 3 all around the opening 9. The sump structure 10 comprises a primary cylindrical bowl 11 which provides a first vessel in communication with the interior of the vessel, and a secondary cylindrical vessel 16, which provides a second vessel surrounding the lower portion of the first vessel. The primary cylindrical cup 11 is continuously connected to the primary diaphragm 7, thus completing it in a sealed manner. Similarly, the secondary cylindrical cup 16 is connected continuously to the secondary membrane 5, which it thus completes sealingly. More specifically, the primary cylindrical bowl 11 comprises a cylindrical lateral wall 12 whose axis is perpendicular to the bearing wall 3 and which has an upper edge substantially aligned with the sealed membrane 7 and a lower edge engaged in the hollow cylindrical bowl 20 below the carrier wall 3. A bottom wall 13 parallel to the carrier wall 3 closes the cylindrical side wall 12 at its lower edge. A flat annular flange 14 is fixed at the upper edge of the cylindrical side wall 12 and protrudes radially outwardly thereof around the primary cylindrical bowl 11. The primary membrane 7 thus has an interruption under the shape of a window, for example a circular or square window, the edge 15 surrounds the sump structure 10 and is sealingly connected to the upper surface of the flat flange 14, for example by welding or gluing. Similarly, the secondary cylindrical cup 16 has a cylindrical side wall 17 whose axis is perpendicular to the bearing wall 3 and which has an upper edge substantially aligned with the secondary waterproof membrane 5 and a lower edge engaged in the hollow cylindrical bowl 20 below the bottom wall 13. A bottom wall 18 parallel to the carrier wall 3 closes the cylindrical side wall 17 at its lower edge. The cylindrical side wall 17 surrounds the cylindrical side wall 12 at a distance therefrom. A planar annular flange 19 is fixed at the upper edge of the cylindrical side wall 17 and protrudes radially outwardly thereof around the secondary cylindrical cup 16. The secondary diaphragm 5 also has an interruption under the a window, for example a circular or square window, the edge 25 surrounds the sump structure 10 and is sealingly connected to the upper surface of the flat flange 19, for example by welding or gluing. In the tank wall 2, the space between the carrier wall 3 and the secondary membrane 5 is a secondary space containing the secondary insulating barrier 4 and in which it is possible to circulate a flow of nitrogen for safety reasons. . In the sump structure 10, the space between the secondary cylindrical bowl 16 and the hollow cylindrical bowl 20 is also a secondary space 27 which communicates with the secondary space of the tank wall 2 to be able to receive this nitrogen sweep. . The secondary insulating barrier 4 is for example formed of modular blocks juxtaposed for relatively uniformly covering the carrier wall 3. These modular blocks stop at a certain distance from the sump structure 10, as indicated by the edge 28. Insulating blocks of suitable shape may be designed to approach the sump structure relatively closely or to fit into it and thereby limit the gap remaining to be filled in the secondary insulation. Insulating materials are housed in the gap 29 between the edge 28 of the secondary insulating barrier 4 and the secondary cylindrical cup 16, as well as in the secondary space 27 of the sump structure 10 to complete the thermal insulation around the Cylindrical secondary bowl 16. Indeed, the secondary membrane 5 and the secondary cylindrical bowl 16 are likely to be in contact with the LNG in the event of accidental leakage into the primary membrane 7. Various insulating materials may be suitable to thereby complete the secondary thermal insulation, for example glass or rock wool, polymeric foams, in particular polyurethane or PVC, balsa, plywood, aerogels, and others. Preferably, the insulating materials housed between the bottom wall 22 and the bottom wall 18 also have sufficient rigidity to structurally support the secondary cylindrical cup 16 and the primary cylindrical cup 11. For this, in FIG. relatively rigid insulating panel 30 is housed between the bottom wall 22 and the bottom wall 18, made for example in the form of a block of polyurethane foam sandwiched between two plywood plates. The insulating panel 30 is attached to the bottom wall 22, for example by fasteners 31 including threaded studs projecting from the bottom wall 22 and engaged in orifices in a peripheral area of the plywood plate. bottom and bolts on the studs. The bottom wall 18 is fixed to the top of the insulating panel 30, for example by similar fasteners cooperating with a peripheral flange 32 of the bottom wall 18 which protrudes radially from the side wall 17. Similarly, in the wall 2, the space between the secondary membrane 5 and the primary membrane 7 is a primary space containing the primary insulating barrier 6 and wherein it is possible to circulate a flow of nitrogen for safety. In the sump structure 10, the space between the primary cylindrical bowl 11 and the secondary cylindrical bowl 16 is also a primary space 33 which communicates with the primary space of the tank wall 2 to be able to receive this nitrogen sweep. . The primary insulating barrier 6 is for example formed of modular blocks 30 juxtaposed for relatively uniformly covering the carrier wall 3. These modular blocks stop at a certain distance from the sump structure 10, as indicated by the edge 34. Insulating blocks of suitable shape may be designed to approach relatively closely the sump structure 10 or to fit into it and thus limit the gap remaining to be filled in the primary insulation. Insulating materials are housed in the gap 35 between the edge 34 of the primary insulating barrier 6 and the primary cylindrical bowl 11, as well as in the primary space 33 of the sump structure 10 to complete the thermal insulation around the cylindrical primary bowl 11. Indeed, the primary membrane 7 and the primary cylindrical bowl 11 are in contact with the LNG during use. Various insulating materials may be suitable to thereby complete the primary thermal insulation, for example glass or rock wool, polymeric foams, especially polyurethane or PVC, balsa, plywood, aerogels, and others. Preferably, the insulating materials housed between the bottom wall 18 and the bottom wall 13 also have sufficient rigidity to structurally support the primary cylindrical bowl 11. For this, in FIG. 1, a relatively rigid insulating panel 36 is housed between the bottom wall 18 and the bottom wall 13, made for example in the form of a block of plywood. The insulating panel 36 is attached to the bottom wall 18, for example by securing devices 37 comprising threaded studs projecting from the bottom wall 18 and engaged in orifices in a peripheral zone of the plywood block. as well as nuts screwed on the studs. The bottom wall 13 is fixed on the top of the insulating panel 36 by the fixing devices 37 cooperating with a peripheral flange 38 of the bottom wall 13 which protrudes radially from the side wall 12. In use, because of its position in below the primary membrane 7, the primary bowl 11 receives by gravity any residue of liquid in the tank, in the manner of a sump. The primary bowl 11 has sufficient capacity to keep the suction head 1 immersed in the liquid for a certain period, for example of the order of 15 s or more. To have good structural stability, the primary bowl 11 and the secondary bowl 16 are made of a more rigid material than the sealed membranes, for example with a metal sheet of the order of 6 to 20 mm thick.
    [0011] With reference to FIGS. 2 to 4, other embodiments of the sump structure will now be described, which are more particularly adapted for a tank wall made according to the technology described in the publications FR-A-2781557 or FR-A A-2961580. Elements similar or identical to those of FIG. 1 bear the same reference number and are only described to the extent that they differ from FIG. 1. In this case, the primary insulation barrier 6 essentially consists of cobblestones. polyurethane foam covered with plywood plates 40 forming the support surface of the primary membrane. The primary membrane, which is omitted in FIGS. 2 to 4, is made by means of thin sheets of embossed sheet that are otherwise known. To fix the embossed sheet metal plates on the plywood plates 40, these are provided with metal plates 41, 42 fixed in counterbores on the top of the plywood plates 40.
    [0012] The structure of the primary membrane in the immediate vicinity of the sump structure can be made identically to the connection between the primary membrane and the support foot as taught in the publication FR-A2961580. Specifically, metal plates 42 attached to the plywood plates 40 surround the flat annular flange 14 of the sump structure at a short distance therefrom, for example forming a square outline for simplicity. Unillustrated closure plates are disposed around the flat annular flange 14 and sealingly welded thereto over its entire periphery. For this, the closure plates are cut in a semicircle at their inner edge, while their outer edge delimits a square and is superimposed on the metal plates 42 around the sump structure to be fixed by welding on the metal plates 42. The primary watertight barrier in the area of the sump 10 is completed, on the one hand by welding the edges of sealed sheets of corrugated sheet on the closure plates, and on the other hand by closing in a sealed manner the possible ends of the undulations stopped there. The structure of the secondary membrane in the immediate vicinity of the sump structure can be carried out in a manner identical to the connection between the secondary membrane and the support foot as taught in publication FRA-2961580 by forming the flange 19 with a square outline. In particular, the secondary membrane consists of a sealed composite sheet 5 bonded to the modular blocks of polyurethane foam constituting the secondary insulating barrier 4. To achieve the continuity of the secondary sealed barrier around the sump structure, four strips 43 of a sealed composite material of aluminum foil and fiberglass are adhered to the plane flange 19 and to the sealed composite ply 5. A strip 43 is positioned each time so as to overlap one side of the flange 19 and the edge 5 alternatively, the flat rim 19 may be formed with a circular contour. In this case, the structure of the secondary membrane in the immediate vicinity of the sump structure can be carried out in a manner identical to the connection between the secondary membrane and the support foot as taught in the French application filed on February 22, 2013 under the deposit number 1351584. The embodiment of Figure 2 also shows special provisions for the support of the primary bowl 11 and the secondary bowl 16. In particular, support legs 45 extend the side wall 17 of the secondary bowl 16, so as to bear against the bottom wall 22. As a result, the insulating materials housed in the secondary space 27, not shown in FIG. 2, do not need to offer structural rigidity as well. high than the insulating panel 30 and may be made of flexible materials. Similarly, a support wall 46 extends the side wall 12 of the primary bowl 11, so as to bear against the bottom wall 18. In this case, the insulating materials housed in the primary space 33, not shown in FIG. 2, do not need to provide a structural rigidity as high as the insulation board 36 and may be made of flexible materials. Orifices 47 in the support wall 46 allow the circulation of a gaseous phase in the primary space. Furthermore, an annular flange 48 is positioned around the side wall 17 to provide an additional support surface in alignment with the carrier wall 3, in particular to support small insulating blocks 49 having a shape adapted to closely surround the The annular flange 48 may be attached to the carrier wall 3 and / or to the side wall 17. The embodiment of FIG. 3 is similar to that of FIG. 2, but it comprises the lower insulating block 30. instead of, or in combination with, the support legs 45. In a variant not shown, for the sake of simplification, the same wall 18 can form the bottom of the primary bowl 11 and the secondary bowl 16. For this purpose, , compared with Figure 3, the wall 13 and the insulating panel 36 are removed and the orifices 47 are plugged. A secondary bowl 10 is obtained which does not pass below the primary bowl 11 but only turns around it. A further degree of simplification is achieved in the embodiment of Fig. 4 where the secondary bowl is completely removed. The plane flange 19 is fixed directly around the side wall 12 of the primary bowl 11, for example by welding. The embodiment of Figure 5 differs from Figure 3 in two aspects. On the one hand, the hollow cylindrical bowl 20 is shallower to limit the bulk of the sump structure outside the carrier wall 3. Thus, the bottom wall 18 of the secondary bowl 16 is here on the inside. 3. On the other hand, the sump structure 10 is here used in combination with a tank wall made according to the technology described in the publication FRA-2798902. Elements similar or identical to those of FIG. 1 bear the same reference numeral and are only described to the extent that they differ from FIG. 1. In this case, the primary insulation barrier 6 and the barrier of FIG. secondary insulation 4 consist essentially of plywood boxes 50 filled with an insulating gasket, for example pearlite, glass wool or other. The primary membrane 7 and the secondary membrane 5 are made by means of 30 parallel strakes with raised edges made of low expansion steel known as invar® which are retained on the cover panels of the plywood boxes 50 by means of elongated solder support.
    [0013] Around the primary bowl 11 the strakes of the primary membrane 7 are cut so as to form a square window 51. The continuity of the primary membrane 7 between the edge of the window 51 and the flat rim 14 can be achieved by means of plates closing as previously described.
    [0014] The embodiments of FIGS. 6 to 8 relate to a sump structure which jointly produces a support leg 110. The elements similar or identical to those of FIG. 1 bear the same reference numeral increased by 100 and are only described in FIG. as far as they differ from FIG. 1. For the sake of clarity, the tank wall is omitted in FIG. 6. The support leg 110 has a hollow form of revolution with a frustoconical lower part 52 flaring downwards by way of stability and bearing on the carrier wall 3, and a right upper part 53. The opening 9 is removed in the embodiment of Figure 6. The primary bowl 111 has a diameter similar to the upper right part 53 and is fixed in the extension thereof within the frustoconical lower portion 52. More specifically, an upper edge of the side wall 112 is sealingly secured to the internal surface of the frustoconical lower portion 52 all around the support foot 110. The secondary bowl 116 has a larger diameter and is fixed below the primary bowl 111 within the frustoconical lower portion 52. More specifically, a upper edge of the side wall 117 is sealingly attached to the inner surface of the frustoconical lower portion 52 all around the support foot 110. On its outer surface, the support foot 110 carries the plane rim 114 at about the same level as the upper edge of the primary bowl 111 and the flat rim 119 approximately at the same level as the upper edge of the secondary bowl 116. As previously, the planar flanges 114 and 119 serve to seal the primary waterproof membranes. and secondary (not shown) around the support foot 110. Inlets 54 are formed through the wall of the light support leg 110. above the rim 114, so as to be slightly above the primary waterproofing membrane. They allow to collect the liquid in the primary bowl 111 by gravity even when the filling level of the tank is below the top 55 of the support leg 110.
    [0015] Similarly, circulation orifices 56 and 57 are formed through the wall of the support leg 110 between the flanges 114 and 119 and under the rim 119, so as to allow the passage of the gaseous phase between the primary space of the wall of vessel and the primary space 133 of the support foot 110, and respectively between the secondary space of the vessel wall and the secondary space 127 of the support foot 110. Making connections between a foot of the support and the membrane primary and the secondary membrane of a vessel wall have been described in the publication FR-A-2961580. These links are applicable to the support foot 110.
    [0016] Figure 7 schematically illustrates another way of making these links. In this embodiment, the vessel wall has a structure similar to Figure 2. The elements similar or identical to those of Figure 2 have the same reference numeral increased by 100. In this case, the edges of the sheet metal plates forming the primary waterproof membrane 7 are welded directly to the flat rim 114 all around the support foot 110. Moreover, the sealed composite strips 143 are stuck astride the plane rim 119 and the water-tight ply 5 of the adjacent modular blocks all around the support foot 110. To increase the capacity of the primary bowl 111, it is possible to combine the support leg 110 with a hollow cylindrical bowl 120 extending outside the carrier wall 103. This combination is illustrated schematically on Figure 8. Thus, the bottom wall of the primary bowl 111 can be moved to the outside of the carrier wall 103 to increase the capacity of the bowl . Another way of adjusting the capacity of the primary cuvette 111 is to vary the diameter of the support foot 110. In preferred embodiments, this diameter is between 0.4 m and 1 m. On the other hand, although cuvettes 111 and 116 have been shown as entirely separate from support foot 110, it is clear that the side wall of support leg 110 could alternatively be the side wall of cuvette 111 or 116 on at least part of its height. It suffices to provide a bottom wall 113 or 118 closing the section of the support leg 110 to the desired level.
    [0017] The embodiments of Figures 9 and 10 relate to a sump structure which remains inside the carrier wall 203 to limit the size of the tank. Elements similar or identical to those of Figure 1 have the same reference numeral increased by 200 and are described only to the extent that they differ from Figure 1. The primary waterproof membrane is omitted. In the embodiment of Figure 9, the primary bowl 211 and the secondary bowl 216 are not attached to each other. The plane rim 214 of the primary bowl 211 is supported in a counterbore on the top of the modular blocks 206 forming the primary insulating barrier where it is fixed. Similarly, the plane rim 219 of the secondary bowl 216 is supported in a counterbore on the top of the modular blocks 204 forming the secondary insulating barrier where it is fixed. Between the supporting wall 203 and the bottom 218 of the secondary bowl 216, the insulating block 230 of relatively thin thickness is preferably made of material with a very high insulating power, for example in aerogels or vacuum insulating panel. Optionally, a relatively rigid block, not shown, can be installed between the bottom 218 and the bottom 213 to improve the support of the primary bowl 211. The secondary waterproof membrane 205 is sealingly connected to the plane rim 219. Preferably, Circulation grooves are provided in the bottom plate 59 of the modular blocks 206, so as to allow the passage of the gas phase between the primary space of the vessel wall and the primary space 233 of the sump structure. The embodiment of FIG. 10 differs from FIG. 9 only by the addition of a frustoconical upper nozzle 58 above the primary bowl 211. This nozzle is provided at its base, just above the watertight membrane. primary not shown, inlet ports 61 controlled by non-return valves not shown, which capture in the frustoconical upper nozzle 58 liquid residues at the bottom of the tank. The techniques described above for making a sump structure can be used in different types of tanks, for example an LNG tank 30 in a floating structure such as a LNG tank or the like. FIG. 11 diagrammatically illustrates the installation of a sump structure, here corresponding to the sump structure 210 of FIG. 9, at the base of a loading / unloading tower 60 in a tank of a LNG carrier, namely at the vertical of the liquid dome of the tank. The loading / unloading tower 60 is supported by a support leg 63 bearing on the carrier wall 3 which is the inner bottom wall of the double hull of the ship. The loading / unloading tower 60 comprises in particular a main pump 62 and an auxiliary pump 1 of smaller flow than the main pump 62. The sump structure 210 is arranged to receive the suction inlet of the auxiliary pump 1. By Moreover, by integrating the sump structure into the thickness of the tank wall, the tank walls 65 can be made according to the usual flat multilayer structure, both at the bottom wall 3 and the transverse cofferdam. 64, and the connection to the sump structure 210 is obtained without significantly deflecting the waterproof membranes of their usual planar geometry. Referring to Figure 12, 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 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 manner known per se, loading / unloading pipes 73 arranged on the upper deck of the ship may be connected, by means of appropriate connectors, at a marine or port terminal to transfer a cargo of LNG to or from the tank 71.
    [0018] FIG. 12 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 fitted to the shore installation 77 and / or pumps fitted to the loading and unloading station 75 are used. Although the invention has been described in connection with several particular embodiments, 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.
