In particular, the invention relates to the field of sealed and thermally insulating vessels in the context of the storage or transport of low temperature liquid gas such as tanks of ships for the transport of liquefied petroleum gas (also called LPG) with for example a temperature between -50 ° C and 0 ° Ο, or for the transport of liquefied natural gas (LNG) at about -162 ° C at atmospheric pressure.
    Technological background
    In order to transfer the liquid from or into a sealed and thermally insulating tank, liquid loading or unloading lines are provided. These pipes develop along a vertical wall of the tank from a ceiling tank wall to a bottom wall of the tank. This arrangement is illustrated for example in document FR3019520 A1.
    During the loading and unloading of the liquefied gas, the temperature change generates thermal deformations, and therefore stresses both the sealed membranes of the tank and the loading and unloading lines. Similarly, during a sea transport, the movement of liquefied gas in the tank exerts significant forces on the walls of the tank and on the pipes. summary

    Detailed description of ways of realizing
    In the description below, several elements will be described arranged in a storage tank and / or transport LNG. The bottom wall of the tank designates a wall, preferably generally flat, located in the bottom of the tank relative to the earth's gravity field. Conversely, the ceiling tank wall designates a wall of the tank, preferably globally flat, located at the top of the tank relative to the earth's gravity field. The general geometry of the tank can also be of different types. Polyhedral geometries are the most common. A cylindrical or other geometry is also possible.
    The walls of the tank are for example formed by a multilayer structure attached to supporting walls and including two alternating waterproof membranes with two thermally insulating barriers. Other tank walls are formed by a simple thermally insulating barrier carried by a carrier wall and a waterproof membrane carried by the thermally insulating barrier. Since there are many known techniques for making these structures of sealed and thermally insulating vessel walls, the description below will be limited to a brief description of the vessel in the context of vessel walls comprising a simple thermally insulating barrier and a sealed membrane and will describe in more detail the structure of the elements cooperating with the pipes arranged in the tank.
    A ship has a double shell forming a supporting structure 1 on which are mounted walls of a tank. Each tank wall comprises a thermally insulating barrier 2 anchored to the supporting structure and a waterproof membrane 3 supported by the thermally insulating barrier 1.
    A plurality of pipes 4 develop vertically from a ceiling tank wall 5 to a bottom tank wall 6. These pipes 4 are suspended from a ceiling-bearing wall 7 of the supporting structure 1. The suspension of the pipes 4 the ceiling-bearing wall 7 can be made in many ways, for example by means of a flange fixed to the ceiling-bearing wall 7 or the like. The pipes 4 successively pass through the ceiling carrying wall 7 and the ceiling tank wall 5 near a transverse tank wall 8. This transverse tank wall 8 develops vertically and connects the bottom tank wall 6 and the ceiling pipe wall 5. The pipes 4 preferably develop over the entire height of the tank to open into the tank closer to the bottom tank wall 6. The pipes 4 are preferably substantially centered at the mid-width of the vessel, along the transverse vessel wall 8.
    The lines 4 can be associated with pumps 9 in order to transfer liquid or gas from or to the inside of the tank. Thus, a tank may comprise one or two pipes 4 intended for unloading liquid or gas from the tank, one or two pipes 4 intended for the loading of liquid or gas into the tank, a pipe 4 intended for the return of gas during a tank loading, a pipe 4 intended for supplying LNG to an engine, or for carrying out an end of unloading the vessel with the aid of a pump of reduced power, etc. The pumps 9 can be carried by the ceiling-carrying wall 7 or integrated with the pipes 4. In one embodiment, a pump 9 comprises a pump body carried by a bridge of the vessel formed by the ceiling-carrying wall 7. The pump body is connected to a shaft housed in the pipe 4. This shaft develops in the pipe 4 from the pump body to the bottom tank wall 6. A pumping propeller is housed in the pipe 4 at the level of the bottom tank wall 6 and connected to the shaft.
    When loading or unloading LNG or in the case of using the LNG contained in the tank to supply gas to the engines of the ship, the lines 4 are used to transfer the LNG. However, due to roll movements that can be caused by the sea on which the ship sails or the activation of the pump 9, the pipes 4 are subjected to stresses and vibrations that can lead to their degradation. These constraints can be all the more important that the tank, and therefore the pipes 4 also, have a high height. It is therefore necessary to maintain the position of the lines 4 in a stable and reliable manner in the tank.
    In order to maintain the pipes in the tank, a plurality of anchoring devices 10 are anchored to a transverse bearing wall 11. This transverse bearing wall 11 develops substantially vertically. The transverse tank wall 8 is anchored to this transverse bearing wall 11. The anchoring devices 10 are anchored at regular spacing on the transverse bearing wall 11. For example, in the context of a tank having a height of 30 meters, a first anchoring device 10 is anchored at approximately 10m height in the tank and a second anchoring device 10 is anchored at approximately 20 meters in height in the tank. The pipes 4 are secured to the anchoring devices 10 to ensure their holding in position in the tank, as explained below.
    Preferably, in order to improve their resistance to stress and their stability in the tank, the pipes 4 are interconnected by stiffeners 12. These stiffeners 12 are, for example, rigid metal bars connecting two adjacent pipes 4 in the tank. A plurality of stiffeners 12 may be disposed between two adjacent ducts along the transverse tank wall 8. For example, as illustrated in FIG. 1, two adjacent ducts 4 may be connected by a first stiffener 12 located between the tank wall. 5 and the first anchoring device 10, a second stiffener 12 located between the first anchoring device 10 and the second anchoring device 12 and a third stiffener 12 located between the second anchoring device 10 and the wall bottom tank 6.
    Figure 2 is a schematic perspective view of the transverse tubular wall 8 with skinned illustrating the anchoring device 10 through the thermally insulating barrier 2 at different stages of mounting the vessel.
    The transverse vessel wall 8 comprises a plurality of insulating boxes 13 of substantially parallelepiped shape arranged in a regular pattern.
    The insulating boxes 13 are for example made of plywood and contain an insulating material such as glass wool or periite. The insulating caissons 13 are anchored to the transverse bearing wall 11 by means of studs (not shown) welded to the transverse bearing wall 11. An inner face 14 of the insulating boxes 13 facing towards the inside of the vessel comprises two strips of anchorage 15 on which are welded sheets of corrugated sheet 16 (see Figures 3, 4, 6 or 8). These anchoring strips 15 are arranged perpendicularly to each other and develop on a central portion of the inner face 14 of the insulating boxes 13. The inner face 14 of the insulating boxes 13 comprises, in the extension of the strips of anchorage 15, thermal protection strips 17.
    The anchoring device comprises a plurality of support legs 18 anchored to the transverse carrier wall 11 and passing through the vessel wall, a beam 19 fixed to said plurality of support legs and, for each conduit, a fixed guide flange 20 on the beam 19.
    The support legs 18 comprise a base 21 and a spacer 22. The base 21 is disposed between two insulating boxes 13 vis-à-vis one another. This positioning between two insulating caissons 13 makes it possible not to modify the part of the insulating caissons 13 carrying the anchor strips 15 and thus to preserve a good fixing surface of the sealed membrane on the insulating caissons 13.
    In addition, the base 21 is centered between two sides of the boxes 13 vis-à-vis. The two insulating boxes 13 between which is positioned the base 21 have a clearance 23 centered on their sides vis-à-vis, these clearance 23 being each of dimensions complementary to the dimensions of one half of the base 21. The clearances 23 are preferably rectangular. The positioning of the base 21 centered on the sides of the two adjacent insulating boxes 13 advantageously limits the number of insulating boxes 13 to be modified to ensure sufficient space for the base 21. In addition, the positioning of the base 21 centered on the sides of two adjacent insulating boxes 13 does not cause changes in the angles of said insulating boxes so that they can cooperate normally with insulating boxes 13 anchoring devices on the wall carrying ceiling 7 located at the levels of angles of said insulating boxes.
    In the embodiment illustrated in FIG. 2, the base 21 has an H-shaped profile. More particularly, the base 21 comprises an anchoring plate 24 constituting a first branch of the H-profile, a spacer 25 constituting the central portion of the H-shaped profile and a sealing plate 26 constituting the second branch of the H-profile. The fuse 21 is preferably metallic.
    The anchor plate 24 is rectangular in shape and made of metallic material. This anchor plate 24 develops parallel to the transverse carrier wall 11. The anchor plate 24 is fixed to the transverse carrier wall 11 by any suitable means, for example by welding. The spacing member 25 extends perpendicularly to the anchor plate 24 through the thermally insulating barrier of the transverse vessel wall 8. The spacer member 21 is attached to the anchor plate by any means adapted, for example by welding. This spacing member 25 comprises for example two plates 27 parallel to each other and perpendicular to the anchoring plate 24. These two plates 27 are interconnected by two secondary plates parallel to each other and perpendicular to both the plates 27 and the anchor plate 25.
    The sealing plate 26 is preferably rectangular. This sealing plate 26 is developed parallel to the transverse carrier wall 11. The sealing plate 26 is fixed on one end of the spacing member 25 opposite the anchoring plate 24. The sealing plate is flush with at the inner face 14 of the insulating boxes 13. The space between the base 21 and the insulating boxes 13 is advantageously filled by an insulating material 28 such as glass wool or polyurethane block or injected. Such an insulating material 28 allows the thermally insulating barrier to maintain good thermal insulation properties despite the presence of the bases 21. In addition, the H-shaped profile of the base 21 makes it possible to limit the presence of thermal bridges between the wall transverse carrier 11 and the sealed membrane of the transverse vessel wall 8. The spacer 22 develops from the base 21 towards the inside of the vessel. In the embodiment illustrated in FIGS. 2 to 4, this spacer 22 comprises a first tab 29 and a second tab 30. The first tab 29 develops perpendicularly to the sealing plate 26. The second tab 30 is developed obliquely by relative to the sealing plate 26. One end of each tab 29, 30 opposite the sealing plate 26 has a support plate 31. The support plates 31 are parallel to the transverse support wall 11.
    In a non-illustrated embodiment, a single support plate is made and is carried jointly by the two legs of the spacer 22.
    In another embodiment not shown, the spacer has only one leg. This single tab is flared so as to have a larger section at its end opposite the sealing plate. The support plate may then be attached and fixed on the end of such a flared tab or be integrally formed by said end of the flare leg.
    The beam 19 is fixed on the support plates formed by a plurality of support legs 18 located at the same height in the tank. The beam 19 is of parallelepipedal shape. The guide flanges 20 are fixed on a face 32 of the beam 19 opposite to the support feet 18. More particularly, a guide flange 20 is fixed on the face 32 of the beam 19 for each pipe 4 to be held in position in tank. Each guide flange 20 is centrally or globally centered in the middle of the support plates 31 of a support leg 18, as can be seen in FIG. 3 at the level of the central support foot 18 or the support foot 18 on the left. on the face. In the case of a single support plate, the guide flange 20 is centered or generally centered on this support plate.
    The guide flange 20 comprises two half-collars associated together to surround a respective pipe 4. Each half-collar is semicircular in shape. The two half-collars each comprise a connecting rib 41. These two connecting ribs 41 are fixed to one another by any suitable means such as for example using screws and nuts or a weld , so that the two half-collars together form the collar surrounding the pipe. The guide flange 20 thus ensures a locking in horizontal displacement of the pipe 4 in the tank. However, an inner face of the collar vis-à-vis the pipe 4 comprises strips of sliding material such as Teflon allowing the sliding of the pipe 4 vertically in the guide flange 20. Thus, the pipe 4 can slide in the guide flange for supporting contraction / expansion of the pipe during loading / unloading of liquid in the vessel.
    The beam 19 may be made of a low coefficient of expansion material such as high manganese steel or nickel to compensate for the length of the latter. Indeed, the anchoring of a large number of pipes 4 requires that the beam 19 has a significant length. Therefore, a contraction or expansion of the beam 19 can cause a shear force on the support legs 18 fixed to the beam 19. The manufacture of the beam 19 in a low coefficient of expansion material also makes it possible to maintain position in the tank the guide flanges 20 fixed on the beam 19 including during significant temperature changes in the tank.
    A first half-collar 33 of the guide flange 20 has a fastening tab 34 which is developed from an outer face of the first half-collar. This fixing lug 34 is cylindrical, for example, of circular section and develops perpendicular to the face 32 of the beam 19. One end of the fixing lug 34 opposite the first half-collar comprises a fixing plate fixed on the face 32 of the beam 19, for example by welding or bolting.
    The first half-collar 33 further comprises a reinforcing rib 35. This reinforcing rib 35 develops in a plane perpendicular to the face 32 of the beam 19. This reinforcing rib 35 is developed along the fixing lug 34 and on the entire outer surface of the first half collar 33.
    A second complementary half-collar 36 of the first half-collar 33 comprises on an external face an anchoring protrusion 37. As illustrated in FIG. 4, this anchoring protrusion 37 comprises a first part developing from the second half-collar 36 and having a first circular clearance 38. A second portion of the anchorage protrusion 37 has a second circular clearance 39 complementary to the first clearance 38. The first portion and the second portion of the anchor protrusion 37 are mounted to the on the other so that the first clearance 38 and the second clearance 39 together form a guide port for a secondary line 40. Such a secondary line 40 may be useful for various functions such as sampling functions or a diffusion function. For example, a secondary sampling line 40 makes it possible to take a small quantity of the liquid contained in the tank at different depths in the tank. A secondary diffusion line 40 makes it possible to take a low temperature liquid from the bottom of the tank and to dispense it at the top of the tank in order, for example, to cool the upper part of the tank. Such secondary lines 40 have a reduced section relative to the lines 4 for unloading or loading liquid into the tank. These secondary lines 40 are advantageously maintained in position in the tank by means of the anchoring protrusion 37. More particularly, these conduits are housed in the guide orifice so that the guide flange 20 maintains its position in position. a main pipe 4 by means of the collar and a secondary pipe 40 by means of the anchoring protrusion 37. The anchoring protrusion 37 advantageously develops in a plane distinct from the junction plane defined by the junction ribs 41. Thus, when the two half-collars 33 and 36 are assembled, the junction by welding, screwing or other junction ribs 41 is not hindered by the presence of the anchoring protrusion 37.
    A guide flange 20 anchoring on the carrier wall both a main duct and a secondary duct 40 may be offset relative to the center of the support plate 31.
    Figure 3 is a schematic perspective view of the transverse tubular wall 8 illustrating the cooperation between support legs 18 and the sealed membrane of the transverse vessel wall 8 at different stages of mounting the vessel.
    The sealed membrane of the transverse tub wall 8 has a plurality of corrugated metal plates. These corrugated metal plates are for example made of steel and have series of vertical corrugations 42 parallel to each other as well as series of horizontal corrugations 43 parallel to each other. These corrugations 42 and 43 allow the waterproof membrane to absorb the constraints related to the contraction of the waterproof membrane during LNG loads in the tank. Such a corrugated waterproof membrane is for example described in the document FR2861060.
    The waterproof membrane comprises, at the right of the sealing plates 26 of each support leg 18, an opening 44. This opening 44 allows the spacers 22 to develop through the sealed membrane of the transverse vessel wall 8. This opening 44 has dimensions smaller than the dimensions of the sealing plate 26. An inner peripheral edge of the opening 44 covers the sealing plate 26. In order to maintain the tightness of the sealed membrane of the transverse tank wall 8, the peripheral edge internal of each opening 44 is sealingly welded to the corresponding sealing plate 26.
    Advantageously, the openings 44 are disposed in the sealed membrane between two adjacent vertical corrugations 42. In addition, the openings 44 are also arranged between two adjacent horizontal corrugations 43. Thus, the openings 44 do not interrupt the undulations 42 and 43 of the waterproof membrane, the waterproof membrane retaining good deformation properties and good resistance to stresses related to thermal contractions.
    FIG. 5 is a sectional view of an alternative embodiment of a base 21 of support foot 18. This variant embodiment is particularly advantageous because it greatly limits the thermal bridges between the transverse carrier wall 11 and the watertight membrane of FIG. the transverse tank wall 8.
    In this variant, the spacing member 25 is formed by two insulating shims, for example two shims made of wood or composite material. A first insulating shim 45 is fixed on the anchoring plate 24. Two threaded rods 46 are fixed, for example by welding, on the anchoring plate 24. These two threaded rods develop perpendicularly to the anchor plate 24 in the thickness of the thermally insulating bamer. The first insulating shim 45 comprises two housings 47 having a pierced bottom 48. The first insulating shim 45 is attached to the anchoring plate 24 so that each threaded rod 46 passes through one of the perforated bottoms 48 of the housings 47. Nuts 49 are mounted on the threaded rods 46 and block the pierced bottom 48 of the housings 47, and thus the first insulating shim 45, against the anchoring plate 24.
    A second insulating shim 50, for example of wood or of composite material, is fixed on the sealing plate 26 in a similar manner to the first insulating shim 45 of the anchoring plate 24.
    The first insulating shim 45 and the second insulating shim 50 further comprise a third housing 51 on a face opposite to the two housings 47. These third housings 51 also comprise a pierced bottom 52. Prior to the mounting of the second insulating shim 50 on the plate sealing member 26, a retaining member having a threaded rod 53 and a head 54 is housed in the third housing 51 of the second insulating shim 50. The head 54 of the retaining member has dimensions such that the retainer can not pass through the pierced bottom 52 of the third housing 51 of the second insulating shim 50. The retaining member is housed in the third housing 51 so that the threaded rod 53 of the retaining member passes through the pierced bottom 52 of the third housing 51 of the second insulating shim 50. In a preferred embodiment, a block of insulating material 55 such as an insulating foam is housed in the housing. third housing 51 of the second insulating shim 50 to improve the thermal insulation characteristics of the base 18.
    The first insulating shim 45 and the second insulating shim 50 are contiguous so that the threaded rod 53 of the retaining member passes through the pierced bottom 52 of the third housing 51 of the first insulating shim 45 and the second insulating shim 51 together. 50. The anchor plate 24 has a through hole 56 vis-à-vis the third housing 51 of the first insulating shim 45 allowing the passage of a nut 57. Such a nut 57 is screwed onto the threaded rod 53 of the retaining member so as to maintain the first insulating shim 45 and the second insulating shim 50 integral, thereby securing the anchoring plate 24 and the sealing plate 26. Such a base 18 comprising a spacer 25 insulation, for example mainly wood or composite materials, avoids the presence of thermal bridges between the anchor plate 24 and the sealing plate 26 while ensuring good mechanical strength.
    Figures 6 and 7 illustrate the conduits at the thermally insulating ceiling barrier.
    In a similar manner to the thermally insulating barrier of the transverse tank wall 8, the thermally insulating barrier of the ceiling tank wall 5 is made from a plurality of parallelepiped insulating boxes 13 juxtaposed in a regular pattern.
    In order not to encroach on the anchor strips 15, the pipes 4 pass through the ceiling tank wall 5 between adjacent insulating caissons 15, that is to say at a distance from the central portions of the insulating caissons 13 carrying the strips. In addition, in order to limit the number of insulating housings 13 that it is necessary to modify in order to let the pipes 4 pass, the pipes 4 pass through the ceiling tank wall 5 while being centered at the sides of the walls. vis-à-vis two adjacent insulating boxes 13. In addition, the passage of the pipes 4 being centered on the sides opposite two adjacent insulating caissons 13, the angles of said insulating caissons 13 are not modified and can cooperate normally with insulating box anchoring devices 13 on the wall carrying ceiling 7 located at the levels of the angles of said insulating boxes 13. The sides vis-à-vis said two boxes are modified so as to have clearances 58 for the passage of a pipe 4. The clearances 58 are preferably rectangular.
    When the tank further comprises secondary lines 40, these secondary lines 40 also pass through the ceiling tank wall between the sides vis-à-vis the adjacent insulating boxes 13 modified for the passage of the main lines 4. The sides of said adjacent insulating boxes 13 are modified, to a lesser extent, in a similar way to the modifications intended for the passage of the lines 4. Similarly, the secondary lines 40 pass through the ceiling tank wall, preferably being as centered as possible. between the sides opposite said adjacent insulating casings 13, or at least without causing modification of the corners delimiting the sides facing said adjacent insulating casings 13. The clearance space between the pipe 4 and the insulating boxes 13 is filled with an insulating material 59 such as glass wool or injected polyurethane in order to maintain the thermal insulation properties of the thermally insulating wall barrier. ceiling tank 5.
    However, in a tank having a sealed metal membrane formed of a plurality of corrugated plates, the corrugations of the plates are offset from the edges of said corrugated plates. Depending on the distance between two adjacent corrugations and the size of the pipes 4, a pipe 4 passing through the thermally insulating barrier of the ceiling tank wall 5 can interrupt the corrugations of the sealed membrane of the ceiling tank wall 5. In addition, the vertical corrugations of the transverse tank wall 8 are generally arranged in the continuity of a series of corrugations of the ceiling tank wall 5. Thus, the pipe 4 can develop vertically in the right of a vertical corrugation carried by the sealed membrane of the transverse tank wall 8 over the entire height of the tank. The support foot 18 as described above with reference to FIGS. 2 to 4 advantageously makes it possible not to interrupt the vertical corrugations of the sealed membrane of the transverse vessel wall 8 while positioning the support plate (s) so as to provide a support for the beam 19 between the pipe 4 and the vertical corrugation in line with the pipe 4. Thus, the beam 19 is fixed on the support leg 18 to the right of a vertical corrugation and provides a reliable and solid anchorage to line 4 without interrupting the vertical ripple at the line 4.
    In order to ensure the tightness of the waterproof membrane of the ceiling tank wall, a metal connecting plate 60 is carried by the two insulating boxes 13 between which the pipe 4 passes. A plywood plate resting on a shoulder formed on an inner face of said insulating caissons 13 can optionally provide a solid and flat bearing surface for the metal connecting plate 60. This metal connecting plate is flush with the inner face of the insulating boxes 13. The metal connecting plate 60, and possibly the plywood plate, comprise a through orifice 61 for the passage of the pipe 4. A secondary through orifice 62 is also provided in the metal connecting plate 60, so that possibly in the plywood plate, for the passage of a possible secondary pipe 40.
    The waterproof membrane of the ceiling vessel wall 5 has a ceiling opening 63. This ceiling opening 63 has dimensions smaller than the dimensions of the metal connecting plate 60 and an inner peripheral edge of the ceiling opening 63 covers the metal connecting plate 60. As shown in FIG. 8, the inner peripheral edge of the ceiling opening 63 is sealingly welded to the metal connecting plate 63. End portions of corrugations 64 are welded to the metal connecting plate 60 and on the undulations of the waterproof membrane of the ceiling tank wall 5 in order to interrupt the corrugations in a sealed manner at the level of the ceiling opening 83. The sealing between the metal connecting plate 60 and the pipe 4 is provided by the presence of a circular flange 65 surrounding the pipe 4 as illustrated in FIG. 66 of this collar 65 surrounds the pipe 4 and is sealingly welded to the pipe 4. An annular portion 67 of the flange 65 rests and is sealingly welded to the metal connecting plate 60 at the edge of the through hole 61. A secondary collar 68 similar but of reduced dimensions is welded together on the secondary pipe 40 and on the metal connecting plate 60 at the edge of the secondary through orifice 62. When the flange 65 is made in two joined parts, as illustrated in Figures 8 and 9, a patch 69 is welded to the junction of the two parts of the flange 65 to seal. A similar patch may be used when the secondary flange 68 is made in two parts as illustrated in FIG.
    The technique described above for producing a tank can be used in various types of tanks, for example to form a tank of an LNG tank in a land installation or in a floating structure such as a LNG tank or other.
    Referring to Figure 10, 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 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. 10 represents an example of a marine terminal including 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.
    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.
    Thus, any number of conduits may be anchored in the vessel using the anchor described above. Similarly, the anchoring device may comprise any number of support legs for fixing the beam stably on the carrier wall. For example, it would be possible for four ducts to be anchored to the load-bearing wall by means of an anchoring device comprising three feet of supports.
    In addition, in one embodiment, the beams 19 may carry an access ladder to the tank in addition to the guide flanges 20.
    Furthermore, the figures and the associated description are mainly made in the context of a corrugated metal membrane having elongated flexible zones in the form of series of parallel vertical corrugations 42 and series of parallel horizontal corrugations 43. However, in an alternative embodiment not shown, the vessel walls could comprise a waterproof membrane in INVAR strakes with raised edges. In such a case, the elongated parallel flexible zones are then constituted by bellows formed by the raised edges welded two by two of two adjacent INVAR plates. By INVAR is meant here a nickel-steel alloy whose thermal expansion coefficient is less than 3.10 at 20 ° C. Such cell walls are for example described in the document FR2527544.
    The anchored conduits may be of any type and include, for example, two discharge lines, a filling line, and possibly a diffusion line as well as possibly secondary lines attached to the large pipes for sampling or diffusion. The use of the verb "to include", "to understand" or "to include" and its conjugated forms does not exclude the presence of other elements or steps other than those set out in a claim. The use of the indefinite article "a" or "an" for an element or a step does not exclude, unless otherwise stated, the presence of a plurality of such elements or steps.
