    (54) WATERPROOF WALL STRUCTURE.
    FR 3 054 871 - A1 _ The invention relates to a sealed and thermally insulating tank comprising:
    - a thermally insulating barrier defining a support surface (1),
    - a metallic waterproof membrane comprising a plurality of metal strakes (9) comprising a flat central portion (10) and two raised lateral edges (11) developing from opposite longitudinal edges of the flat central portion (10), the thermally insulating barrier having a housing hollowed out from the support surface (1) and having a retaining zone (20), at least one said metal strake (9) constituting an anchor strake (4) comprising an anchor wing (22) attached to the flat central portion (14) and extending in the retaining zone (20) so as to retain the anchor strake (4), each lateral edge raised from the anchor strake (4) being welded so watertight at a raised lateral edge (11) of a respective adjacent metal strake (9).

    Technical area
    The invention relates to the field of sealed and thermally insulating tanks for the storage and / or transport of fluid, such as a cryogenic fluid.
    Sealed and thermally insulating tanks are used in particular for the storage of liquefied gas such as methane (LNG) or petroleum (LPG), which is stored, at atmospheric pressure. These tanks can be installed on the ground or on a floating structure.
    Technological background
    We know, for example from FR-A-2798358, FR-A-2709725, FR-A2549575 or FR-A-2398961, storage or transport tanks for liquefied gases at low temperature including the or each waterproof membrane , in particular a primary waterproof membrane in contact with the product contained in the tank, consists of thin metal sheets which are carried by a thermally insulating barrier. These thin metal sheets are tightly connected to each other to ensure the tightness of the tank.
    FIG. 1 illustrates a known method of fixing said metal sheets to the thermally insulating barrier in this type of tank. In this FIG. 1, an upper surface 101 of the thermally insulating barrier has a groove 102 developing in the thickness of the thermally insulating barrier from the support surface 101. This groove 102 has in the thickness of the thermally insulating barrier a retaining zone formed by a groove 103 which develops parallel to the support surface 101. This groove 103 develops at the end of its groove 102 opposite the support surface 101 in the thickness of the thermally insulating barrier , the groove 102 having a cross-section in the shape of an “L” whose base is formed by the groove 103. An anchoring wing 104 in the shape of an “L” is inserted in the groove 102. This anchoring wing 104 has a base 105 housed in the groove 103 so as to retain the anchoring wing 104 on the thermally insulating barrier in a direction perpendicular to the surface of support 101. The anchoring wing 104 further comprises an anchoring branch 106 of which a lower part 107 is contiguous with the base 105 and an upper part 108 protrudes above the support surface 101.
    Two metal sheets 109 are arranged on either side of the anchoring wing 104. These metal sheets 109 each have a flat central portion 110 bearing on the support surface 101 (for the sake of readability of the figure, the support surface 101 and the metal sheets 109 are shown in Figure 1 with a gap). These metal sheets 109 also have raised side edges, hereinafter called raised edges 111. A raised edge 111 of each of the two adjacent metal sheets 109 is welded on either side of the anchoring branch 106 of the anchor wing 104.
    The raised edges 111 thus form, with the anchoring wing 104, bellows making it possible to absorb the forces associated with the contraction of the waterproof membrane, for example when loading cryogenic liquid into the tank.
    However, such an anchoring wing 104 constitutes a fixed fixing point for each raised edge 111. In fact, the anchoring wing 104 being biased in two opposite directions by the raised edges 111, it remains substantially static in the tank. . Consequently, the anchoring of the raised edges 111 on the support surface 101 via the anchoring wings 104 is substantially fixed. The flexibility of the waterproof membrane is therefore limited.
    summary

    Detailed description of embodiments
    In the description below, reference is made to a waterproof membrane in the context of a sealed and thermally insulating tank. Such a tank has an internal space intended to be filled with combustible or non-combustible gas. The gas may in particular be a liquefied natural gas (LNG), that is to say a gaseous mixture mainly comprising methane as well as one or more other hydrocarbons, such as ethane, propane, n-butane, ibutane, n-pentane i-pentane, neopentane, and nitrogen in small proportion. The gas can also be ethane or a liquefied petroleum gas (LPG), that is to say a mixture of hydrocarbons resulting from the refining of petroleum comprising essentially propane and butane.
    The waterproof membrane rests on a support surface 1 formed by a thermally insulating barrier of the tank. Such a thermally insulating barrier is formed of juxtaposed insulating elements. For example, suitable insulating elements are described in document WO2012 / 072906. The insulating elements are anchored to the supporting structure by retaining members. Each of the insulating elements has the shape of a rectangular parallelepiped having two large faces, or main faces, and four small faces, or lateral faces. These insulating elements each comprise a cover panel 13, an upper face of the cover panels 13 forming the support surface 1.
    The waterproof membrane has a repeated structure alternately comprising, on the one hand, metal sheet strips 9 disposed on the support surface 1 and, on the other hand, elongated weld supports 4 linked to the support surface 1 and extending parallel to the sheet metal strips 9 over at least part of the length of the sheet metal strips 9. The sheet metal strips 9 have raised side edges 11 disposed and welded against its adjacent welding supports 4. Such a structure is for example used in LNG tankers of the NO96 type sold by the applicant.
    FIG. 2 is a sectional view of a portion of a sealed and thermally insulating tank wall at the level of a weld support 4 according to a first embodiment, the weld support 4 being linked to two adjacent metal strips 9 arranged on either side of said welding support 4.
    The sheet metal strips 9 have a flat central portion 10 developing along the longitudinal direction of the sheet metal strip 9. The raised edges 11 of the sheet metal strips 9 are located on either side of the flat central portion 10, c ' that is to say along two opposite longitudinal edges of the planar median portion 10. A single raised edge 11 of each of the two adjacent metal strips 9 is shown in FIG. 2. Each raised edge 11 protrudes from the surface of support 1.
    The weld support 4 allowing the anchoring of the sheet metal strips 9 to its thermally insulating barrier has a shape analogous to the shape of the sheet metal strips 9. Thus, the weld support 4 has an elongated shape. The welding support 4 has a flat central portion 14. The welding support 4 also comprises two welding wings 15 similar to the raised edges 11 of the sheet metal strips 9. These welding wings 15 are elongated and develop from the longitudinal edges of the flat central portion 14. These weld wings 15 project towards the inside of its tank from the support surface 1.
    The weld support 4 is arranged parallel to the sheet metal strips 9, the sheet metal strips 9 and the weld support 4 having the same longitudinal direction. The weld support 4 is interposed between two adjacent sheet metal strips 9. Thus, the waterproof membrane is made up of standard strakes formed by the sheet metal strips 9 alternated with anchor strakes formed by the welding supports 4. Such an anchor strake preferably has a width less than the width of the common strakes .
    In order to anchor the weld support 4 on the thermally insulating barrier, the cover panel 13 of the insulating element 12 on which the weld support 4 is anchored has a clearance area 16 in the form of an elongated corridor in the longitudinal direction. of the welding support 4. This clearance 16 comprises a flat bottom 17. The flat bottom 17 is bordered on each of its longitudinal sides by a shoulder 18. An upper face of the shoulder 18 and an upper face of the flat bottom 17 are parallel on the upper face of the cover panel 13.
    An added piece 19 of parallelepipedal shape is inserted into the recess 16 on each longitudinal side of the said clearance 16. These inserts 19 have a thickness equal to the depth of the clearance 16 at the shoulders 18. Thus, the inserts 19 are flush with the level of the upper face of the cover panel 13 forming the support surface 1. Typically, the support surface 1 is formed jointly by the upper face of the cover panel 13 and by the upper face of the inserts 19. Furthermore, these inserts 19 have a width greater than the width of the shoulder 18. Thus, its inserts 19 project laterally from the shoulder 18 above the flat bottom 17.
    The cover panel 13 thus has a depression area 35 in the form of a longitudinal corridor delimited by a side face 36 of the inserts 19. In other words, a central area 21 of the bottom bottom 17 is not covered by its pieces 19. This depressed area 35 also has two housings 20 in the form of lateral grooves located at the bottom of the bottom 17. Each housing 20 is delimited by a lateral end of the bottom bottom 17, that is to say distinct from the area central 21, a side face of the shoulder 18 and a bottom face of the added piece 19 facing said side end of the bottom piat 17. These housings 20 develop laterally from the central area 21 of the bottom bottom 17 which is not covered by its inserts 19. This central zone 21 has a width substantially equal to the width of the central portion of the frame 14 of the welding support 4.
    The weld support 4 has two anchor wings 22. Each anchor wing 22 projects laterally from a respective longitudinal edge of the plane central portion 14. The weld support 4 is inserted into the cover panel 13 by sliding the along the longitudinal direction of the depressed area 35. More particularly, the weld support 4 is inserted into the depressed area 35 so that on the one hand the central section 14 of the weld support 4 rests on the central area 21 of the flat bottom 17 and, on the other hand, its anchoring wings 22 are housed in a respective housing 20. Thus, the central zone 21 of the flat bottom 17 also constitutes a portion of the support surface 1 on which the flat central portion 14 of the weld support rests. Each weld wing 15 of the weld support 4 develops in thickness. of the cover panel 13 along the lateral face 36 of a respective insert 19 and projects from the upper face of said insert 19. The insertion by longitudinal sliding of the anchoring wings 22 in the housings 20 allows a anchoring the weld support 4 in a direction perpendicular to the support surface 1 while allowing the welding support 4 to slide on the cover panel 13 in a longitudinal direction of the weld support 4.
    A raised edge 11 of each of the two metal strips 9 adjacent to the weld support 4 is welded by a weld sign 23 to a respective weld wing 15 of the weld support 4. Thus, each raised edge 11 forms with one welding wings 15 a bellows capable of deforming to absorb the contraction forces of the waterproof membrane.
    The sealed welds between the raised edges 11 of the sheet metal strips 9 and the welding wings 15 can be carried out in many ways. Thus, to make its welding lines 23 over long lengths, welding machines (not shown) can be used. The welds can be carried out using electric welding machines, for example as described in His documents FR-A-2172837 or FR-A-2140716. Such a welding machine moves along the weld lines 23 while being held pressed against the sheet metal strips 9 of which it performs the welds of the raised edges 11. According to another embodiment, the weld line 23 binding the raised edges 11 and the weld wings 15 is produced by a seam weld.
    During a contraction of the waterproof membrane, each raised edge 11 moves away from the corresponding welding wing 15 by deforming. In addition, when such a contraction of the waterproof membrane occurs, the weld wings 15 also deform in the direction of the sheet metal strips to which they are linked to absorb the stresses associated with the contraction of the membrane. Thus, the waterproofing membrane has good flexibility allowing it to absorb the stresses linked to the thermal contraction of the waterproof membrane.
    FIG. 3 is a schematic perspective view of a portion of a sealed and thermally insulating tank wall at the level of the weld support according to a second embodiment, the weld support being linked to two adjacent strips of sheet metal arranged on one side and on the other of said weld support, the waterproof membrane being in a non-contracted state. In this figure, the elements identical or fulfilling the same function as the elements described with reference to FIG. 1 have the same reference.
    This second embodiment differs from the first embodiment by the structure of the weld support 4. Unlike the first embodiment illustrated in FIG. 2 in which the weld support 4 is made in one piece, the weld support 4 according to the second embodiment is produced by assembling a first part 24 and a second part 25. The cover panel 13, and therefore the depression area 35 and its housings 20, is similar to the cover panel 13 described below. above next to His figure 2.
    In this second embodiment, the first part 24 is of elongated shape and has a “U” section. A base of the “U” section of this first part 24 forms the flat central portion 14 of the welding support 4. Branches of the “U” section of this first part 24 form the welding wings 22 of the welding support 4.
    The second part 25 of the welding support 4 is in the form of a flat metal plate and is attached to the first part 24 of the welding support 4. This second part 25 is fixed to a lower face of the flat central portion 14 formed by the first part 24. The second part 25 has a length identical to the length of its first part 24. However, its second part 25 has a width greater than its width of the flat central portion 14 of the first part 24. The second part 25 is fixed to the first part 24 so as to project laterally along the opposite longitudinal edges of the flat central portion 14. Thus, lateral ends 27 of the second part 25 project laterally from each longitudinal side of the first piece 24. These lateral ends form the anchoring wings 22 of the welding support 4 and are housed in the housings 20 of the pannel. cover water 13.
    The second part 25 is fixed to the first part 24 for example using a longitudinal weld sign 28 centered on the flat central portion 14 formed by the first part.
    In a variant not illustrated, the connection between the first part 24 and the second part 25 is produced by two longitudinal weld lines situated at the level of the lateral ends of the planar central portion 14 of the first part 24.
    FIG. 4 is a schematic perspective view of a portion of a sealed and thermally insulating tank wall at the level of a weld support according to a third embodiment, the weld support being linked to two adjacent sheet metal strips arranged at on either side of said weld support. Figure 5 is a sectional view of a portion of a sealed and thermally insulating tank wall at the weld support of Figure 4. In these Figures 4 and 5, the elements identical or fulfilling the same function as the elements described opposite ia Figure 1 bear the same reference.
    This third embodiment differs from the second embodiment illustrated in FIG. 3 in that the first part 24 is welded to a plurality of second parts 25. Each second part has a length less than the length of the first part 24. The second pieces 25 are arranged regularly along the first piece 24.
    In this third embodiment, the clearance 16 does not include a shoulder 18. The second parts 25 of the welding support 4 are directly anchored on the bottom 17 for example using rivets 26 as illustrated in FIG. 4. In addition, the clearance 16 has a depth taken in the thickness of the cover panel 12 substantially equal to the depth of the second parts 25. An upper face of the lateral ends 27 of the second parts 25 is therefore flush with the upper surface of the panels. cover 12.
    Figure 6 is a schematic sectional representation of a tank in which the sheet metal strips 9 are arranged in a transverse direction of a ship in which the tank is housed.
    The carrying structure of the tank is here constituted by the internal hull of a double-hull ship, the bottom wall of which has been shown in number 29, and by transverse partitions, which define compartments in the internal hull of the ship. On each wall of the supporting structure, a corresponding wall of the tank is produced. Each wall of the tank successively comprises, in the thickness direction of the tank, from the outside to the inside, a secondary thermally insulating barrier 30, a secondary waterproof membrane 31, a primary thermally insulating barrier 32 and a waterproof membrane primary 33.
    The secondary 31 and primary 33 waterproof membranes each consist of a series of sheet metal strips 9 parallel to the raised edges 11, which are arranged alternately with welding supports 4 described above with reference to FIGS. 2 to 5. This alternating structure is produced over the entire surface of the walls of the tank, which can involve very long lengths.
    In FIG. 6, the raised edges 11 are arranged in a longitudinal direction perpendicular to the longitudinal direction of the ship. Thus, the raised edges 11 constitute bellows making it possible to absorb the contraction forces in a longitudinal direction of the ship. The sheet metal strips 9 and the welding supports 4 are interrupted at the angles parallel to its longitudinal direction of the ship, for example as described in document WO 2012/072906 or else FR2724623.
    Figure 7 is a detail view of Figure 6 illustrating an angle of the tank. In such a tank angle, the support surfaces 1 of its thermally insulating barrier of two adjacent tank walls form an angle, for example of the order of 135 °. In order to ensure the seal between the waterproof membranes at this angle of the tank, the support surfaces 1 are covered with a plurality of juxtaposed corner pieces 37. These corner pieces 37 have an angle analogous to the angle formed between the support surfaces 1 of two adjacent walls.
    The sheet metal strips 9 of the two walls of the tank forming the corner of the tank are tightly welded to the corner pieces 37. The sealing between two successive corner pieces 37 is ensured by the presence of corrugated pieces 38 which are welded on the one hand to the two adjacent corner pieces 37 and, on the other hand, to the sheet metal strips 9 of the two walls of tanks forming the angle at the junction between the two corner pieces 37. The corrugated parts 38 are offset in the direction of the angle of the tank with respect to the weld supports 4 so that a weld support 4 is not opposite a corrugated part 38 the along the angle of His tank. One end of the sheet metal strips 9 forming the junction of the waterproof membrane at the corner optionally has a cut parallel to the raised edges 11 covered by the corrugated parts 38 in order to allow the deformation of said corrugated parts 38 and the absorption of stresses of contractions. The waterproof membrane thus has, along any straight line perpendicular to the longitudinal direction of the sheet metal strips 9, a flexibility equal to or greater than the flexibility of said sheet metal strips 9.
    An embodiment of the corrugated parts 38 of the waterproof tank membrane at a te! tank angle is for example described in Se document FR3004507, with reference to FIGS. 6 and 7. Furthermore, the interruption of the raised edges 11 of the sheet metal strips 9 as well as of the welding supports 4 can be carried out according to the methods described in WO 2012/072906 or FR2724623.
    Figure 8 is a schematic sectional representation of a tank in which the sheet metal strips 9 of the secondary waterproof membrane are arranged in a longitudinal direction of a ship in which the tank is housed. This FIG. 8 illustrates a tank angle between a longitudinal wall of the tank and a transverse wall of the tank, the longitudinal direction of the sheet metal strips 9 of the longitudinal walls of the tank being parallel to the longitudinal direction of the vessel comprising the tank. In this FIG. 8, the walls of the tanks comprise, as in FIG. 5, two thermally insulating barriers and two waterproof membranes. For the sake of readability, only the secondary waterproof membrane is visible in FIG. 8, the description below applying in an identical manner to the primary waterproof membrane not shown.
    The tank comprises at each angle formed by the transverse wall a connecting ring 39 in the form of a tube which makes it possible to take up the tension forces resulting from the thermal contraction, from the deformation of the hull to the sea and from the movements of Sa cargo. Such a connection ring 39 is for example described in document WO 2012/072906 or also in document FR-A-2549575.
    The connecting ring 39 is anchored on the support structure and comprises a wing 40 developing parallel to the angle of the support structure, that is to say perpendicular to the longitudinal direction of the sheet metal strips 9. The strips of sheet 9 are interrupted before the connecting ring
    39. A bending portion 41 allows the watertight junction between the wing 40 of the connection ring 39 and a terminal end of the sheet metal strips 9.
    The bending portion 41 is described in more detail with reference to FIG. 9. This bending portion 41 comprises a plurality of corner strakes arranged parallel to the angle of the tank, that is to say perpendicular to the strips sheet metal 9.
    An external corner strake 42 has a flat portion 43 welded over its entire length to the wing 40 of the connecting ring 39. This external corner strapping 42 has on a longitudinal edge opposite to the connecting ring 39 a raised edge 44 similar to the raised edges 11 of the sheet metal strips 9.
    An internal corner strake 45 has a flat portion 46 onto which the ends of the sheet metal strips 9 are welded. This internal corner strake 45 has, on a longitudinal edge opposite the sheet metal strips 9, a raised edge 47 similar to the raised edges. 11 sheet metal strips 9.
    The internal corner strake 42 and the external corner strake 45 are connected by a central corner strake 48 having a structure similar to the sheet metal strips 9, that is to say a flat central portion 49 whose edges longitudinal each have a raised edge 50. The raised edges 44, 47 and 50 of the strakes of adjacent angles 42, 45 and 48 are interconnected.
    At least one connection between the raised edges 44, 47 and 50 of two adjacent corner strakes 42, 45 and 48 is produced by means of a corner weld support 51 anchored on in the thermally insulating barrier. Such a corner weld support 51 is arranged parallel to the angle of the tank and has a structure similar to the weld supports 4 or 104 described above.
    Thus, in FIG. 9, a wing 40 of the connection ring 39 is successively observed on which the external corner strake 42 is welded. The raised edge 44 of the external corner strake 42 is anchored on the barrier insulating via the angle weld support 51 analogous to the weld support 104 described with reference to FIG. 1. A first raised edge 50 of a first central corner strake 48 is also welded on this weld support angle 51 on one side of the angle weld support 51 opposite the raised edge 44. A second raised edge 50 of the first central corner strake 48 opposite the weld support 51 is directly welded to a first raised edge 50 of a second central corner strake 48. A second raised edge 50 of the second central corner strake 48 opposite the first central corner strake 48 is directly welded to the raised edge 47 of the internal corner strake 45 .E Finally, the sheet metal strips 9 are directly welded to the internal corner strake 45. The raised edges 11 of the sheet metal strips 9 are interrupted before the bending portion 41 in the usual way, for example as described in document WO 2012 / 072906.
    In an embodiment not shown, the angle weld support 51 is formed by a transverse angle anchoring strake similar to the weld support 4 described above with reference to FIGS. 2 to 5.
    The bending portion 41 comprises at least the internal corner strake 45 and the external corner strake 42. The number of central corner strakes 48 can vary from 0 to N, N being an integer, depending on the flexibility of the desired waterproof membrane. Indeed, the connection between the different raised edges 44, 47 and 50 of the adjacent corner strakes 42, 45 and 48 forms a bellows making it possible to absorb its thermal contraction stresses in a direction perpendicular to the longitudinal direction of the sheet metal strips. 9. In Figure 9, N is 2.
    Similarly, the number of angle weld supports 51 can be variable, the bending portion 41 comprising at least one connection between two raised edges 44, 47 and 50 of adjacent corner strakes 42, 45 and 48 comprising a support angle weld 51.
    In certain cases and those in order to avoid making work in compression the sheets of sheet metal, a prestress in tension is applied during welding.
    FIG. 10 is a schematic representation of a variant of the waterproof membrane illustrated in FIGS. 6 and 7. In this variant, its sheet metal strips 9 are interrupted on a central portion connecting together two angles of the tank, for example substantially in the middle of the tank wall. This interruption is achieved by a transverse bending portion 52. This transverse bending portion 52 develops perpendicular to the longitudinal direction of the sheet metal strips 9.
    The transverse bending portion 52 is produced in a similar manner to the bending portion 41 described above with reference to FIGS. 8 and 9. Thus, on the waterproof membrane shown in FIG. 10 the transverse bending portion 52 has two transverse strakes end 53 and two central transverse strakes 54. The transverse end strakes 53 are similar to the internal and external corner strakes 45 and 42. The central transverse strakes 54 are similar to the central corner strakes 48. The transverse strakes central 54 are interposed between the transverse end strakes 53. The transverse end strakes 53 are symmetrical with respect to the central transverse strakes 54. The sheet metal strips 9 interrupted on either side of the transverse bending portion 52 are welded to a respective end transverse strake 53. The raised edges of the different transverse strakes 53 and 54 are connected to each other directly or by means of a transverse welding support. This transverse weld support is analogous to the weld supports described above with reference to FIG. 1 or from FIGS. 2 to 4. The transverse bending portion comprises at least one transverse weld support similar to the weld support 104 described opposite of Figure 1 or similar to the weld support 4 described with reference to one of Figures 2 to 5. The raised edges 11 of the sheet metal strips 9 and the weld supports 4 interrupted by the transverse bending portion 52 are interrupted so usual as for example as described in document WO 2012/072906 or also in document FR-A-2549575.
    With reference to FIGS. 6 to 10, it is possible to alternate welding supports as described above with reference to FIGS. 2 and 3 and conventional welding supports 104 as described with reference to FIG. 1. The alternation of such weld supports 4 and 104 may, for example, have an alternation ratio of a weld support as described with reference to FIGS. 2 and 3 for a weld support 104 of FIG. 1, or even a alternation ratio of one for two or one for N. Likewise, it is possible to alternate welding supports as described above with reference to FIGS. 2 and 3 with bellows formed by direct welding between two raised edges 11 of adjacent sheet metal strips 9. Such alternations are, for example, of the order of a welding support 4 every two sheet metal strips 9, every three sheet metal strips 9 or even all the N sheet metal strips 9.
    Furthermore, the sheet metal strips 9 and the welding supports 4 described above with reference to FIGS. 2 to 5 are, for example, made of invar®, 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, the expansion coefficient of which is typically of the order of 7.10 ' 6 K 1 . Other alloys can also be used.
    The technique described above for producing a waterproof membrane of a sealed and thermally insulating tank can be used in different types of tanks, for example to constitute the waterproof membrane of an LNG tank in a land installation or in a floating structure such as an LNG tanker or other.
    With reference to FIG. 11, a cutaway view of an LNG tanker 70 10 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 waterproof barrier intended to be in contact with the LNG contained in the tank, a secondary waterproof barrier arranged between its primary waterproof barrier and the double hull 72 of the ship, and two insulating barriers arranged respectively between the primary waterproof barrier and the secondary waterproof barrier and between the secondary waterproof barrier and the double shell 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 maritime or port terminal for transferring a cargo of LNG from or to the tank 71.
    FIG. 6 represents an example of a maritime terminal comprising a loading and unloading station 75, an underwater pipe 76 and a shore installation 77. The loading and unloading station 75 is a fixed offshore installation comprising an arm mobile 74 and a tower 78 which supports the mobile arm 74. The mobile arm 74 carries a bundle of insulated flexible pipes 79 which can be connected to the loading / unloading lines 73. The mobile arm 74 can be adjusted to suit all of its LNG carrier sizes . A connection pipe, not shown, extends inside the tower 78. The loading and unloading station 75 allows the loading and unloading of the LNG carrier 70 from or to the onshore installation 77. This comprises liquefied gas storage tanks 80 and connecting pipes 81 connected by the submarine pipe 76 to the loading or unloading station 75. The submarine pipe 76 allows the transfer of liquefied gas between the loading or unloading station 75 and the shore installation 77 over a long distance, for example 5 km, which makes it possible to keep the LNG carrier 70 at a 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 in no way limited thereto and that it includes all the technical equivalents of the means described as well as their combinations if these are within the scope of the invention.
    The use of the verb "comprise", "understand" or "include" and its conjugated forms does not exclude the presence of other elements or steps than those set out in a claim.
    In the claims, any reference sign in parentheses cannot be interpreted as a limitation of His claim.
