Description

Storage facility for liquefied gases
Technical Field
The present invention relates to the field of storage facilities for liquefied gases, comprising sealed and thermally insulated membrane tanks. In particular, the present invention relates to the field of sealed and insulated tanks for storing and/or transporting liquefied gases at cryogenic temperatures, such as tanks for transporting Liquefied Petroleum Gas (LPG) at temperatures, for example, between and including-50 ℃ and 0 ℃, or for transporting Liquefied Natural Gas (LNG) at atmospheric pressure at about-162 ℃. These tanks may be mounted on land or on a floating structure. In the case of a floating structure, the tank may be intended for transporting liquefied gas or for receiving liquefied gas used as fuel to propel the floating structure.
Background
Document FR2991430 describes a storage facility for liquefied gases comprising a sealed and insulated tank integrated into a support structure comprising the double hull of a ship. Each wall of the tank includes a secondary insulating barrier, a secondary sealing membrane, a primary insulating barrier, and a primary sealing membrane.
In the region at the top of the tank, the tank comprises a chimney-shaped projection called the liquid dome. In this region, the support structure is locally interrupted so as to delimit a loading/unloading opening intended to have a fluid loading/unloading duct passing through it. Further, still in this region, the support structure comprises: a vertical supporting wall called a coming section (coming), which rises above the deck of the ship; and a horizontal wall at the top of the vertical support wall, which forms an upper structure on the deck of the vessel, called dome-shaped seat. The horizontal wall of the dome-shaped seat extends around the opening and supports the cover.
However, such installation with a dome-shaped seat means that the loading/unloading pipes intended for the entry/exit of the liquefied gas contained in the tank also have to extend in height direction above the deck on the dome-shaped seat, which results in bulky installations that are difficult for maintenance/management of access to these pipes, as well as expensive and heavy structures on the deck of the ship.

The tank walls 71 are thus connected to one another in such a way that a polyhedral structure is formed and an inner storage space 9 is delimited.
For loading and unloading the tank 71 with liquefied gas, the storage facility 1 comprises a loading/unloading opening 10, which loading/unloading opening 10 locally interrupts the outer upper support wall 5, the inner upper support wall 4 and the top wall 7 of the tank, so that the loading/unloading pipe 11 can reach the bottom of the tank 71 after passing through this opening 10.
The storage facility 1 likewise comprises a loading/unloading tower 13 positioned in line with the opening 10 and inside the tank 71, forming a support structure for the loading/unloading pipe 11 and for the pump (not shown) over the entire height of the tank 71.
Furthermore, the storage facility 1 comprises a cover 12, which is arranged in the loading/unloading opening 10 to close the internal storage space 9 at the level of said opening 10. The cover 12 comprises an aperture 14 enabling the loading/unloading duct 11 to pass through the cover 12.
In the first embodiment shown in fig. 1 and 2, the tank 71 also comprises a chimney 15 located on the main structure 6 at the level of the opening and enabling the tank walls to extend continuously from the inner deck 4 towards the outer deck 5 at a level where the outer deck 5 is interrupted by the loading/unloading opening 10. In a liquefied gas storage tank, such a flue 15 provided with a cover 12 is called a liquid dome.
The invention is herein described with reference to the region of the liquid dome, but it is equally envisaged that the invention could be applied to some other chimney of the tank 71, such as a conventional gas dome.
The loading/unloading opening 10 and the flue 15 have a rectangular profile. The flue 15 thus comprises four walls, one of which is an extension of the rear cofferdam wall 8, as visible in figure 1, while the other three walls are connected to the top wall 7 and form an angle of 90 ° with the latter.
Another particular feature of this embodiment shown in fig. 1 and 2 is that the cover 12 is located at the level of the outer deck 5, i.e. enclosing the flue 15.
Fig. 2 schematically shows the opening area of the storage facility 1 in more detail in the first embodiment.
The tank 71 is a membrane tank 71 capable of storing liquefied gas. The main structure 6 of the tank 71 comprises a multilayer structure comprising, from the outside towards the inside: a secondary thermal insulation barrier 16 comprising an insulating element against the support structure; a secondary sealing film 17 against the secondary insulating barrier 16; a primary insulating barrier 18 comprising insulating elements against the secondary sealing film 17; and a primary sealing membrane 19 intended to come into contact with the liquefied gas contained in the tank 71.
According to one embodiment, the main part of the tank 71The structure 6 is according to Mark described in particular in the document FR- A-2691520
Figure BDA0003734884900000091
Produced by a technique.
In this main structure 6, the secondary thermal insulation barrier 16, the primary thermal insulation barrier and the secondary sealing film 17 substantially comprise juxtaposed panels on a support structure, which may be the internal support structure 2 or a structure connecting the internal upper support wall 4 to the external upper support wall 5 at the level of the opening 10. The secondary sealing film 17 is formed of a composite material comprising an aluminum sheet sandwiched between two glass fiber mats. The primary sealing membrane 19 is obtained as such by assembling a plurality of metal plates welded to one another along their edges and comprising corrugations 20 extending in two perpendicular directions. The metal plate is formed of, for example, stainless steel or aluminum sheet formed by bending or pressing. The primary sealing film 19 is shown in particular in fig. 3.
Further details of such corrugated metal membranes are described in particular in FR- A-2861060.
As can be seen in fig. 2, in the chimney 15, the secondary sealing membrane 17 is fixed at its edges to the support structure by means of connecting rings 21 projecting from the inner surface of the chimney support wall, which acts in this region as a wall connecting the inner deck 4 to the outer deck 5.
The cover 12 likewise comprises a multilayer structure comprising, from the outside towards the inside, an upper cover wall 22, a lower cover wall 23 and a thermal insulation structure 24 between the lower cover wall 23 and the upper cover wall 22. The cover 12 also includes a reinforcement 25 on the upper cover wall 22.
As can be seen in fig. 2, the cover 12 is arranged in the loading/unloading opening 10 such that the upper cover wall 22 is located in the plane of the outer upper support wall 5 or outer deck 5. Thus, the storage facility 1 does not comprise a dome-shaped seat, and the cover 12 does not protrude above the outer deck 5.
The upper cover wall 22 is fixed in a sealing manner to the outer deck 5 around the opening 10, so that at the height of the cover 12, the upper cover wall 22 serves as a secondary sealing membrane 17. The upper cover wall 22 is made of metal, such as stainless steel.
The lower cover wall 23 is welded in a sealed manner to the primary sealing membrane 19 of the main structure 6, here the chimney 15, by means of a connection 26. The connector 26 will be described in more detail with reference to fig. 3 and 4. The lower cover wall 23 is likewise welded in a sealing manner to the loading/unloading duct 11.
The insulating structure 24 of the cover 12 comprises a plurality of insulating elements juxtaposed to one another, which may be similar or different. In a preferred mode, the insulating elements positioned in line with the lower cover wall 23 and the connectors 26 are structured insulating elements, while the insulating elements located at the periphery of the insulating structure 24 are unstructured insulating elements, the so-called "structured" insulating elements having substantially greater or even much greater mechanical properties or characteristics than the so-called "unstructured" insulating elements. The structured insulating element may be a block of high-density polymer foam, optionally reinforced with fibers or plywood, or a composite box filled with an insulating filler, such as glass wool, polymer foam or perlite. The unstructured insulating elements may be low density polymer foam blocks or glass wool blocks.
The connection 26 comprises a first flange 27 welded in a sealed manner to the sealing membrane of the main structure 6 and a second flange 28 connected to the first flange 27 and welded in a sealed manner to the lower cover wall 23 around the lower cover wall 23. This connection 26 is designed differently depending on the design of the lower cover wall 23, for example according to a first variant shown in fig. 3 or according to a second variant shown in fig. 4.
Fig. 3 shows the interior of the tank 71 at the junction between the main structure 6 and the cover 12, showing a first variant of the connection 26.
In this fig. 3, the lower cover wall 23 is formed by an assembly of planar metal plates 29, which planar metal plates 29 are welded to each other in a stack. Here, these planar metal plates 29 are planar metal plates 29 having a low thermal expansion coefficient, in this case, between 0.5 × 10 -6 K -1 And 2X10 -6 K -1 And include 0.5x10 -6 K -1 And 2X10 -6 K -1 So that there is little contraction of the liquefied gas as it passes through the loading/unloading line 11. The planar metal plate 29 is made of, for example, an iron-nickel alloy called invar.
In each of the variants, the connection 26 is made of a material having the same coefficient of thermal expansion as the material of the lower cover wall 23, so as to contract and expand in a uniform manner with the lower cover wall 23.
Thus, in this first variant, the connection 26 is also made of a material having a thickness of between 0.5x10 -6 K -1 And 2x10 -6 K -1 An iron-nickel alloy having a thermal expansion coefficient therebetween. Thus, the connection 26 is formed by a continuous strip formed around the lower cover wall 23. The strip is made using one or more connecting elements forming a first flange 27 and a second flange 28.
In an embodiment not shown, the connector 26 comprises a third flange, which lies in the same plane as the first flange 27 and is connected to the first flange 27 and the second flange 28 to form a T-section connector 26. The third flange is fixed to the support structure, forming an anchor for the primary sealing membrane 19 and the lower cover wall 23 at the level of the connector 26. The first flange 27 and the third flange may be formed in one piece. Alternatively, the first flange 27 and the second flange 28 may be formed from the same plate that has been bent.
One of the loading/unloading ducts 11 is shown in fig. 3, passing through the cover 12 and in particular through the lower cover wall 23 via one of the apertures 14 formed in the cover 12. In order to connect the loading/unloading duct 11 and the lower cover wall 23 in a sealed manner, the duct 11 is provided with a flange 30 welded in a sealed manner around the duct, which flange 30 is also welded in a sealed manner to the lower cover wall 23.
Fig. 4 shows a second variant of the connecting element 26. In fact, it is advantageous for the adapting connection 26 when the lower cover wall 23 is made or constituted in the same way as the primary sealing membrane 19 of the main structure 6.
As can be seen in fig. 4, the lower cover wall 23 comprises a plurality of corrugated metal sheets 31, which corrugated metal sheets 31 are juxtaposed in a repeating pattern and welded together in a sealing manner. The corrugations 20 of the lower cover wall 23 are aligned with the corrugations 20 of the primary sealing membrane 19 of the main structure 6. In order to produce this continuity at the level of the connection 26 and also to seal this connection, the connection 26 is formed by a plurality of first connection elements 32 and a plurality of second connection elements 33. The first connecting element 32 is formed by a first flat plate 34 forming part of the first flange 27 and a second flat plate 35 forming part of the second flange 28 to form an L-shaped cross-sectional element. The second connecting element 33 is formed by a first corrugated plate 36 comprising corrugations 38 and forming part of the first flange 27 and a second corrugated plate 37 comprising corrugations 38 and forming part of the second flange 28. The first and second connection elements 32, 33 are arranged in an alternating manner around the lower cover wall 23.
Thus, the corrugations 37 of the second connecting element 33 are aligned with one of the corrugations 20 of the sealing membrane of the main structure 6 and also with one of the corrugations 20 of the lower cover wall 23, as can be seen in fig. 4. The second connecting element 33 can thus ensure the continuity of the bellows at the level of the connection 26, while sealing by engaging the edges of the primary sealing film 19 and the lower cover wall 23.
Fig. 5 and 6 show a second embodiment of the storage facility 1. In contrast to the first embodiment, the upper cover wall 22 is here placed in the plane of the inner upper support wall 4 or the inner deck 4. In this embodiment, therefore, the main structure 6 of the tank 71 does not include the chimney 15 and terminates in its portion above the containment wall 7. Thus, the cover 12 is an extension of the sealing wall 7, so that the loading/unloading pipe 11 and the loading/unloading tower 13 can pass without the cover 12 protruding from the inner deck 4 and, more particularly, from the outer deck 5. The cover 12 may connect the sealing wall 7 to the rear cofferdam wall 8 in line with the opening. The outer deck 5 may be provided with closure elements which are positioned in line with the openings so as to close the outer deck 5 after insertion of the loading/unloading pipes 11 and the covers 12.
Fig. 6 schematically shows in a more detailed manner the open area of the storage facility 1 in a second embodiment. The design of the cover 12 in this embodiment is very similar to that of the first embodiment. The lower cover wall 23 is however in the same plane as the primary sealing membrane 19 of the sealing wall 7 and is connected in a sealed manner to the primary sealing membrane 19 on three of the edges of the lower cover wall 23, the fourth edge being connected to the primary sealing membrane 19 of the rear cofferdam wall 8 as in the first embodiment by means of the elements of the L-shaped or T-shaped section connection 26. Thus, the connection 26 comprises three edges connected to the connecting element of the top primary sealing membrane 19 at the level of the three edges for which the first flange 27 and the second flange 28 are formed in the same plane.
The liquefied gas intended to be stored in the tank 71 may in particular be Liquefied Natural Gas (LNG), that is to say a gas mixture comprising mainly methane and one or more other hydrocarbons. The liquefied gas can likewise be ethane or Liquefied Petroleum Gas (LPG), that is to say a mixture of hydrocarbons produced by petroleum refining, mainly comprising propane and butane.
Referring to fig. 7, a cross-sectional view of a methane tanker vessel 70 shows a sealed and insulated tank 71 of generally prismatic shape mounted in the double hull 72 of the vessel. The walls of the tank 71 comprise a primary sealing barrier intended to be in contact with the LNG contained in the tank, a secondary sealing barrier arranged between the primary sealing barrier and the double hull 72 of the ship, and two thermal insulation barriers arranged between the primary sealing barrier and the secondary sealing barrier and between the secondary sealing barrier and the double hull 72, respectively.
In a manner known per se, a loading/unloading pipe 73 provided on the top deck of the ship may be connected to a marine or harbour terminal by means of suitable connections for transporting the LNG cargo from the tank 71 or to the tank 71.
Figure 7 shows an example of a marine 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 and comprises a moving arm 74 and a tower 78 supporting the moving arm 74. The moving arm 74 carries a bundle of insulated flexible tubes 79 which can be connected to the loading/unloading duct 73. The orientable mobile arm 74 is suitable for all methane tank loading specifications. A not shown connecting duct runs inside the tower 78. The loading and unloading station 75 is capable of loading or unloading the methane tank 70 from the onshore facility 77 to the onshore facility 77. The onshore facility 77 comprises a liquefied gas storage tank 80 and a connection pipeline 81 connected to the loading or unloading station 75 via the subsea pipeline 76. The underwater pipeline 76 enables the liquefied gas to be transported over a large distance, for example 5km, between the loading or unloading station 75 and the onshore facility 77, which enables the methane tanker to be kept at a large distance from shore during loading and unloading operations.
Pumps mounted on the vessel 70 and/or pumps provided at onshore facilities 77 and/or pumps provided at the loading and unloading station 75 are used to generate the pressure required to deliver the liquefied gas.
Although the invention has been described in connection with a number of specific embodiments, it is clear that the invention is in no way limited thereto and that the invention comprises all technical equivalents of the means described and combinations thereof if 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.
