Description
Technical Field
The present invention relates to the field of sealed and thermally insulated tanks with membranes for storing and/or transporting fluids such as liquefied gases.
Sealed thermally insulated tanks with membranes are particularly used for storing Liquefied Natural Gas (LNG), which is stored at about-163 ℃ at atmospheric pressure. These tanks may be installed onshore or on a floating structure. In the case of a floating structure, the tank may be intended to transport liquefied natural gas or to receive liquefied natural gas for use as fuel to propel the floating structure.
Background
Document WO 2014/096600 discloses a sealed and thermally insulated tank for storing liquefied natural gas, which is arranged in a supporting structure and has a wall with a multilayer structure, i.e. from the outside to the inside of the tank: a second level thermal insulation barrier anchored against the support structure; a second level sealing film supported by the second level thermal insulation barrier; a primary thermal insulation barrier supported by the secondary sealing film; and a first stage sealing membrane supported by the first stage thermal insulation barrier and intended to be in contact with liquefied natural gas stored in the tank.
Each primary and secondary thermal insulation barrier comprises a set of insulating plate elements having a substantially parallelepiped shape, respectively primary and secondary insulating plate elements, which are juxtaposed and thus form support surfaces for respective sealing films. The insulation panels are anchored on the support structure by means of anchoring means attached to the support structure and positioned in the corners of the first and second level insulation panels. Thus, each anchoring device engages the corners of four adjacent second stage insulation panels and engages the corners of four adjacent first stage insulation panels so as to hold the same against the support structure.
The second-stage insulating panel member is easily deformed. In fact, the secondary insulation panel is subjected to a thermal gradient which tends to cause the secondary insulation panel to bend due to differential shrinkage phenomena. Furthermore, the deformation of the support structure causes deformation of the second-stage insulation panel member. This is particularly the case when the support structure is formed by the inner hull and when this defines a ballast tank. Indeed, in these cases, the movement of the ballast liquid in the ballast tanks tends to cause significant deformation of the support structure.
The effect of these deformations of the secondary insulation panel pieces is to create steps between adjacent corners of the secondary insulation panel pieces, wherein these steps are even larger when the secondary insulation panel pieces have a specific structure in their corners, for example by being provided with pillars in their corners.
However, when the liquefied gas exerts hydrostatic and dynamic pressure on the walls of the tank, such steps result in the confinement being concentrated in the second stage sealing film and the first stage insulation panel, coinciding with the corners of the second stage insulation panel. Furthermore, the level of constraint in these areas is particularly liable to degrade the aforementioned elements, such as for example crushing and/or perforating the first stage insulation panel.
Disclosure of Invention
One idea behind the invention relates to limiting the level of restraint that tends to be created in the parts of the tank wall that coincide with the corners of the secondary insulation panel members.
One idea behind the present invention is to propose a sealed and thermally insulated tank for storing a fluid, the tank comprising a tank wall having, in order from the outside to the inside of the tank in the thickness direction of the tank wall, a thermal insulation barrier anchored to a support structure and a sealing membrane resting against the thermal insulation barrier, wherein the thermal insulation barrier comprises insulation plates having a parallelepiped shape juxtaposed on the support structure and each having a cover plate defining a support surface for the sealing membrane, wherein anchoring means are attached to and engaged with the support structure between and in order to hold the first and second insulation plates against the support structure, wherein at least one of the anchoring means comprises: -a bar attached to the support structure between at least two adjacent corner regions of at least two adjacent insulation panel pieces; -a support fixture mounted on the rod and held against the support region of each of the adjacent insulation panel pieces towards the support structure so as to hold the insulation panel pieces towards the support structure; and-a force distribution plate which is attached to the supporting fixture and which is arranged between the covering plate of the insulating plate element and the sealing membrane in the corner region of each of the adjacent insulating plate elements.
Such a force distribution plate allows to reduce the step phenomenon between adjacent insulation panel pieces. Furthermore, the effect of the force distribution plate is to distribute constraints that are easily exerted on the sealing film or any other component of the tank wall, for example coinciding with the corner regions of the insulating panel pieces, such as plywood or insulating polymer foam, which allows to limit the level of said constraints and thus to avoid damage to the components of the tank wall.
According to other advantageous embodiments, such a tank may have one or more of the following features.

According to one embodiment, the force distribution plate rests against the cover plate of each of the four adjacent insulation plate elements.
According to one embodiment, the second stage insulation panel comprises a countersunk portion and the force distribution plate is received in one of the countersunk portions of each of the adjacent insulation panels. This helps to ensure that the support surface of the sealing membrane is flat.
According to one embodiment, the force distribution plate is flush with the level of the support surface defined by the cover plate.
According to one embodiment, the countersunk head is manufactured in the corner region.
According to one embodiment, the force distribution plate has a rectangular shape and preferably a square shape.

According to one embodiment, the anchoring device comprises: a nut engaged with the threaded end of the rod; and one or more elastic washers threadedly coupled to the rod between the nut and the secondary support fixture so as to apply an elastic force pressing the secondary support fixture against the support region of each of the four adjacent insulation panel pieces. This makes it possible to provide elastic anchoring of the insulating panel on the support structure.
According to one embodiment, the resilient washer is a Belleville washer.
According to one embodiment, the insulation panel pieces comprise recesses in their corner regions arranged to coincide with the support regions, each second-stage support fixture being received in the recess of a respective one of the adjacent insulation panel pieces.

An advantage of this configuration is that it allows the bending forces generated by the different shrinkage of the material of the insulating sheet element to be limited.
According to one embodiment, the recess is provided in the second insulating polymer foam layer such that the intermediate plate protrudes with respect to the second insulating polymer foam layer and thus provides one of the support areas.
According to one embodiment, the first insulating polymer foam layer has a cut-out in each of the corner regions of the insulating panel piece, the cut-outs receiving posts extending between the base plate and the intermediate plate. This allows for a limitation of the crushing and creep of the foam.

According to one embodiment, the upper fixture includes two faces orthogonal to the thickness direction of the tank wall, the two faces being connected together by a face extending parallel to the thickness direction of the tank wall, the face extending parallel to the thickness direction of the tank wall being connected together by a fillet. This helps to further limit the perforation phenomenon of the first-stage insulation panel member. This also allows the force exerted on the force distribution plate to be limited.
According to one embodiment, the anchoring device comprises a spacer attached to the secondary support fixture and disposed between the secondary support fixture and the upper fixture. The spacer is advantageously made of wood or plastic, which allows to limit the thermal bridge on the anchoring means towards the support structure.

Detailed Description
By convention, the terms "outer" and "inner" are used to define the position of one element relative to another with reference to the interior and exterior of the tank.
Fig. 1 shows a multilayer structure of a wall 1 of a sealed and thermally insulated tank for storing liquefied fluids such as Liquefied Natural Gas (LNG). Each wall 1 of the tank comprises, in order from the outside to the inside of the tank in the thickness direction: a second level of thermal insulation barrier 2 held to a support structure 3; a second stage sealing film 4 resting against the second stage thermal insulation barrier 2; a primary thermal insulation barrier 5 resting against the secondary sealing film 4; and a first stage sealing membrane 6 intended to be in contact with the liquefied natural gas contained in the tank.
The support structure 3 may in particular be formed by the hull of a ship or a double hull. The support structure 3 comprises a plurality of walls defining the general shape of the tank, which is generally polyhedral in shape.
The second stage thermal insulation barrier 2 comprises a plurality of second stage insulation panel members 7 which are anchored to the support structure 3 by means of anchoring means 55, which will be described in detail below. The second-stage insulation panel members 7 have a substantially parallelepiped shape and are arranged in parallel rows.
Fig. 5 shows the structure of the second-stage insulation board member 7 according to an embodiment. In this case, the second stage insulating panel 7 comprises three panels, namely a base panel 8, an intermediate panel 9 and a cover panel 10. The base plate 8, the intermediate plate 9 and the covering plate 10 are made of, for example, plywood. The second stage insulating panel member 7 further comprises a first insulating polymer foam layer 11 sandwiched between the base plate 8 and the intermediate plate 9 and a second insulating polymer foam layer 12 sandwiched between the intermediate plate 9 and the cover plate 10. First and second insulating polymer foam layers 11, 12 are adhered to the base plate 8 and the intermediate plate 9 and to the intermediate plate 9 and the cover plate 10, respectively. The insulating polymer foam may in particular be a polyurethane based foam, optionally reinforced with fibres.
The first insulating polymer foam layer 11 has cutouts in the corner regions for the passage of corner posts 13. Corner posts 13 extend between the base plate 8 and the intermediate plate 9 at the four corner regions of the second stage insulating plate member 7. The corner posts 13 are attached to the base plate 8 and the intermediate plate 9, for example by means of clips or screws or glue. The corner posts 13 are made of, for example, plywood or plastic. The corner posts 13 allow some of the service compression loads to be absorbed and allow the crushing and creep of the foam to be limited. Such corner posts 13 have a coefficient of thermal shrinkage different from that of the first insulating polymer foam layer 11. Furthermore, when the tank is cooled, the deflection of the second stage insulation panel 7 is smaller at the corner posts 13 than in other areas. This further increases the effect of the difference in level or step at the corner regions of the second stage insulation panel member 7.
Furthermore, the second stage insulation panel 7 comprises recesses 14, 54 in its corner regions for accommodating anchoring means 55, which will be described below. The second-stage insulating panel 7 comprises a first recess 14 from the base plate 8 to the intermediate plate 9 intended to pass the stem 15 of the anchoring means 55. The second stage insulating plate member 7 includes a second recess 54 above the intermediate plate 9. The second recess 54 is larger than the first recess 14 such that the intermediate plate 9 protrudes with respect to the second insulating polymer foam layer 12 and the covering plate 10. The intermediate plate 9 thus forms, at the corner regions of the second-stage insulating plate 7, support regions 16 intended to engage with the second-stage support fixtures 17 of the anchoring means 55.
Furthermore, the covering panel 10 has countersunk heads 18 at its four corner regions. Each countersunk head 18 is intended to receive a force distribution plate 19 of an anchoring device 55 described below. The thickness of the countersunk head 18 is substantially similar to the thickness of the force distribution plate 19, so that the force distribution plate 19 is flush with the upper surface of the cover plate 10. The cover plate 10 also comprises a recess 20 for receiving a welding support.
The structure of the second-stage insulation panel member 7 is described above by way of example. Furthermore, in another embodiment, the second-stage insulating panel 7 can easily have another general structure, such as the one described in document WO 2012/127141. The second stage insulation panel 7 is then produced in the form of an outer shell comprising a base plate, a covering plate and a support web extending between the base plate and the covering plate in the thickness direction of the tank wall 1 and delimiting a plurality of cells filled with an insulating lining such as perlite, glass wool or rock wool.
In another embodiment, the secondary thermal insulation barrier 2 comprises a secondary insulation panel member 7 having at least two different types of structures, for example two of the aforementioned structures, depending on its mounting area in the tank. Thus, in certain areas of the tank wall 1, adjacent secondary insulation panel members 7 tend to behave differently as they experience a thermal gradient, which tends to amplify the step phenomenon between adjacent corners of the secondary insulation panel members 7.
With further reference to FIG. 1, it can be seen that the second level sealing film 4 comprises a continuous layer of metal strakes 21 having raised edges. The strakes 21 are welded via their raised edges to parallel welding supports attached in grooves 20 provided on the cover plates 10 of the secondary insulation plate elements 7. The strakes 21 are made of Invar @, i.e. having a coefficient of expansion typically in the range of 1.2X 10-6To 2X 10-6 K-1With an alloy of iron and nickel in between.
The primary thermal insulation barrier 5 comprises a plurality of primary insulation panel members 22 which are anchored to the support structure 3 by means of the aforementioned anchoring means 55. The first-stage insulation panel member 22 has a substantially parallelepiped shape. Furthermore, the dimensions thereof are the same as those of the first-stage insulation panel member 22 except for the thickness thereof in the thickness direction of the tank wall 1, which tends to be different and particularly small. Each of the primary insulation panel members 22 is positioned in line with each of the secondary insulation panel members 7, aligned in the thickness direction of the tank wall 1.
Fig. 6 illustrates the structure of the first stage insulation panel member 22 according to one embodiment. The first-stage insulation panel member 22 has a multilayer structure similar to that of the second-stage insulation panel member 7 of fig. 5. Further, the first-stage insulation panel member 22 includes, in order, a base plate 23, a first insulating polymer foam layer 24, an intermediate plate 25, a second insulating polymer foam layer 26, and a cover plate 27. The insulating polymer foam may in particular be a polyurethane based foam, optionally reinforced with fibres.
The first stage insulation panel member 22 comprises recesses 28 in its corner regions so that the base plate 23 protrudes with respect to the first insulating polymer foam layer 24, the intermediate plate 25, the second insulating polymer foam layer 26 and the cover plate 27. The base plate 23 thus forms, at the corner regions of the primary insulating plate elements 22, support regions 29 intended to engage with the primary support fixtures 30 of the anchoring devices 55. A shim, not shown, may be added to the base plate 23, said shim having a shape similar to that of the support area 29 and being intended to engage with the first stage support fixture 30 of the anchoring device 55.
The base plate 23 comprises a recess 31 intended to receive the raised edge of the strake 21 of the second level sealing film 4. The cover plate 27 also includes a groove 32 for receiving a weld support.
The structure of the first-stage insulation panel member 22 is described above by way of example. Furthermore, in another embodiment, the first stage insulating sheet element 22 can easily have another general structure, such as the one described in document WO 2012/127141.
In another embodiment, the primary thermal insulation barrier 5 comprises a primary insulation panel member 22 having at least two different types of structures, such as the two aforementioned structures, depending on its mounting area in the tank.
With further reference to fig. 1, it can be seen that the first stage sealing membrane 6 comprises a continuous layer of metal strakes 33 having raised edges. The strakes 33 are welded via their raised edges to parallel welded supports attached in grooves provided on the cover plates 27 of the primary insulation plate elements 22.
As shown in fig. 2, the anchoring devices 55 are positioned at four corners of the primary insulation panel member 22 and the secondary insulation panel member 7. Each stack of second level insulation sheets 7 and of first level insulation sheets 22 is anchored to the support structure 3 by means of four anchoring means 55. Furthermore, each anchoring device 55 engages with the corners of four adjacent second stage insulation panel pieces 7 and with the corners of four adjacent first stage insulation panel pieces 22.
Fig. 2 to 4 show the structure of the anchoring device 55 according to the first embodiment.
The anchoring means 55 comprise a bush 34, the base of which is welded to the support structure 3 in a position corresponding to the gap at the corner region of four adjacent second stage insulation panels 7. The bush 34 houses a nut 35 as shown in fig. 4, into which the lower end of the rod 15 is screwed. The rod 15 passes between adjacent first stage insulation panel members 22.
The rod 15 passes through a bore provided in an insulating plug 36 intended to ensure continuity of the second level of thermal insulation at the anchoring means 55. The insulating plug 36 has a cross-shaped cross section defined by four branches in a plane orthogonal to the thickness direction of the tank wall 1. Each of the four branches is inserted into a gap provided between two of the four adjacent second-stage insulation panel members 7.
The anchoring means 55 also comprise a second level supporting and fixing member 17 which abuts, towards the supporting structure 3, a supporting region 16 provided in each of the four adjacent second level insulating panels 7, so as to hold them against the supporting structure 3. In the illustrated embodiment, the second stage support fixture 17 is received in a second recess 54 provided in the second insulating polymer foam layer 12 of each of the second stage insulation panel pieces 7 and abuts an area of the intermediate panel 9 forming a support area.
The nut 37 engages threads provided at the upper end of the rod 15 to retain the second stage support fixture 17 on the rod 15.
In the illustrated embodiment, the anchoring device 55 further comprises one or more resilient washers 38 of Belleville type. An elastic washer 38 is screwed onto the rod 15 between the nut 37 and the second stage supporting fixture 17, which ensures the elastic anchoring of the second stage insulation panel 7 on the support structure 3. Furthermore, advantageously, the locking member 39 is welded locally to the upper end of the rod 15, so as to fix the nut 37 in position on the rod 15.
The anchoring device 55 further comprises a force distribution plate 19, an upper fixture 40 and a spacer 41 attached to the second stage support fixture 17.
A force distribution plate 19 is received in each of the countersunk portions 18 provided in the cover plates 10 of four adjacent second stage insulation plate elements 7. Thus, the force distribution plate 19 is positioned between the cover plate 10 and the second level sealing membrane 4 of each of the four second level insulation plate elements. The force distribution plate 19 is intended to reduce a step phenomenon between the corners of the adjacent second-stage insulation panel members 7. Furthermore, the force distribution plate 19 allows to distribute the constraints that are easily imposed on the secondary sealing film 4 and on the primary insulation plate 22 that coincide with the corner regions of the secondary insulation plate 7. The force distribution plate 19 thus limits the perforation of the base plate 23 of the primary insulation panel 22 and the perforation and compaction of the insulating polymer foam layers 24, 26 of the primary insulation panel 22 in correspondence with the corner regions of the secondary insulation panel 7.
The force distribution plate 19 is advantageously made of a metal chosen from: stainless steel, iron and nickel alloys such as Invar, having an expansion coefficient typically in the range of 1.2X 10 ®-6To 2X 10-6 K-1To (c) to (d); and alloys of iron and manganese having an expansion coefficient of less than 2 x 10-5 K-1Typically about 7 x 10-6K-1. The thickness of the force distribution plate 19 is between 1 and 7 mm, preferably between 2 and 4 mm, for example about 3 mm. The force distribution plate 19 is advantageously square-shaped, with one of its sides between 100 and 250 mm, for example about 150 mm.
The upper fixture 40 is arranged below the force distribution plate 19 and smaller than the force distribution plate 19, so that the force distribution plate 19 completely covers the upper fixture 40. The upper fixing member 40 is accommodated in a recess 54 provided in the corner region of the secondary insulation panel 7, in correspondence with the support region 16, i.e. in the recess 54 provided in the second insulating polymer foam layer 12 of the secondary insulation panel 7, in the embodiment shown in fig. 5.
The upper fixture 40 has a threaded bore 42 in which a threaded base of a pin 43 intended to anchor the first stage insulation plate member 22 is mounted. To allow the pins 42 to be secured to the upper fixture 40, the force distribution plate 19 also includes a bore disposed facing the threaded bore of the upper fixture 40 and thus allowing the pins 43 to pass through the bore of the force distribution plate 19.
The upper fixture 40 has a substantially rectangular parallelepiped shape including: two large opposite faces parallel to the supporting structure 3 of the wall 1; and four faces connecting the two large faces and extending parallel to the thickness direction of the tank wall 1. In the embodiment shown in fig. 2 to 4, four faces extending parallel to the thickness direction of the tank wall 1 are connected by rounded corners 44. This allows avoiding the presence of sharp edges and helps to further limit the perforation phenomenon of the base plate 23 of the first stage insulation plate member 22 by limiting the concentration of the constraints.
In one embodiment, the upper fixture 40 and the force distribution plate 19 are formed as a single, one-piece. Such an element is shown in cross-section in fig. 9.
The spacer 41 is disposed between the second stage support fixture 17 and the upper fixture and thus serves to maintain a gap between the second stage support fixture 17 and the upper fixture 40. In the embodiment shown in fig. 2 to 4, the spacer 41 has a chamfer 45 so as to fit within the overall dimension of the upper fixing 40 as viewed in the thickness direction of the tank wall 1. In other words, the upper fixture 40 completely covers the spacer 41.
The spacer 41 is advantageously made of wood, which allows the thermal bridge towards the support structure 3 to be limited at the anchoring means 55. The spacer 41 is in the form of an inverted U to define a central housing 46 between the two limbs of the U. The central housing 46 houses the upper end of the rod 15, the locking member 39, the nut 37 and the resilient washer 38. The spacer 41 is also housed in a recess 14 provided in correspondence with the support surface 16.
The locking member 39 is square or rectangular in shape, with a diagonal greater than the size of the central housing 46 between the two branches of the U-shape, which blocks the rod 15 from rotating relative to the spacer 39 and thus prevents disengagement of the rod 15 from the nut 35.
In order to attach together the force distribution plate 19, the upper mount 40, the spacer 41 and the second-stage support mount 17, the aforementioned elements are each provided with two bores, each of which is penetrated by a screw 47, 48. The bores provided in the second stage support fixture 17 each have a thread which engages one of the threaded rods 47, 48 to attach the aforementioned elements together.
Furthermore, the pins 43 pass through perforations provided through the strakes 21 of the secondary sealing film 4. The pin 43 has a collar 49 welded around the perforation to the periphery of the pin to seal the secondary sealing membrane 4. Thus, the second stage sealing membrane is sandwiched between the collar 49 of the pin 43 and the force distribution plate 19.
The anchoring means 55 also comprise a primary bearing fixture 30 which, towards the supporting structure 3, abuts on a bearing zone 29 provided in each of the four adjacent primary insulating panels 22, so as to hold them against the supporting structure 3. In the embodiment shown, each support area 29 is formed by a portion protruding from the base plate 23 of one of the primary insulating plate members 22. The primary support fixture 30 is received in a recess 28 provided in the corner region of the primary insulation panel member 22 in line with the support region 29.
The nut 50 engages threads provided at the upper end of the pin 43 to attach the first stage support fixture 30 to the pin 43. In the embodiment shown, the anchoring means 55 also comprise one or more elastic washers 51 of Belleville type, screwed onto the pin 43 between the nut 50 and the first stage holding fixture 30, which ensure the elastic anchoring of the first stage insulating plate elements 22 to the supporting structure 3.
Furthermore, as shown in fig. 4, insulation plugs 52 are inserted into recesses 28 provided in the corner regions of four adjacent first level insulation panels 22 above the anchoring means 55 in order to ensure continuity of the first level thermal insulation barrier 5 at the anchoring means 55. Furthermore, as shown in fig. 4, the wooden closing plate 53 ensures that the support surface of the first-stage sealing film 6 is flat. The closure plate 53 is received in a countersunk portion provided in the corner region of the first stage insulation panel 22.
Fig. 7 shows an anchoring device 55 according to another alternative embodiment. This anchoring device 55 differs from the anchoring device 55 described and illustrated with reference to fig. 2 to 4 in that the upper fixing piece 40 and the spacer 41 have a cross section in a plane orthogonal to the thickness direction of the tank wall 1 without fillets and chamfers, which facilitates the manufacture thereof.
Referring to fig. 8, a cross-sectional view of an LNG tanker 70 shows a sealed and insulated tank 71 having a generally prismatic shape installed in the double hull of a ship 72. The walls of the tank 71 include: a first stage of sealing barrier intended to be in contact with the LNG contained in the tank; a second stage of sealing barrier disposed between the first stage of sealing barrier and the double hull of vessel 72; and two insulating barriers arranged between the first and second stage sealing barriers and between the second stage sealing barrier and the double hull 72, respectively.
In a manner known per se, a loading/unloading line 73 provided on the upper deck of the ship may be connected to the sea or to a harbour terminal by means of suitable connectors for transferring LNG cargo from or to the tank 71.
Fig. 8 shows an embodiment of an offshore terminal comprising a loading and unloading station 75, a subsea pipeline 76 and an onshore facility 77. The loading and unloading station 75 is a fixed offshore installation comprising a movable arm 74 and a turntable 78 supporting the movable arm 74. The movable arm 74 supports a bundle of insulated flexible tubes 79 that can be connected to the loading/unloading line 73. The orientable movable arm 74 is suitable for all forms of LNG tanker. Connecting conduits (not shown) extend inside the turntable 78. The loading and unloading station 75 allows the LNG tanker 70 to be loaded from and unloaded to an onshore facility 77 comprising a liquefied gas storage tank 80 and a connecting pipeline 81 connected to the loading or unloading station 75 by a submarine pipeline 76. The underwater pipeline 76 allows the transfer of liquefied gas over a substantial distance, e.g., 5 km, between the loading or unloading station 75 and the onshore facility 77, which enables the LNG tanker 70 to be maintained at a substantial distance from shore during loading and unloading operations.
In order to generate the pressure required for transferring the liquefied gas, pumps on board the vessel 70 and/or pumps equipped with onshore facilities 77 and/or pumps equipped with loading and unloading stations 75 are used.
Although the invention has been described with respect to a number of specific embodiments, it is clear that the invention is by no means limited thereto and that the invention comprises all technical equivalents of the means described and combinations thereof as long as they fall within the scope of the invention.
Use of the verb "comprise" or "comprise" and its conjugations does not exclude the presence of elements or steps other than those stated in a claim.
In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
