Description

Self-supporting box suitable for supporting and insulating sealing film
Technical Field
The present invention relates to the field of sealed and thermally insulated tanks built into load bearing structures to contain fluids, in particular membrane tanks for containing liquefied gases, in particular combustible gases. The invention also relates in particular to a wooden self-supporting box suitable for the support and insulation of the membrane of such tanks.
Background
Sealed insulated tanks may be used in different industries to store fluids. For example, in the energy field, liquefied Natural Gas (LNG) is a liquid with a relatively high methane content that can be stored at about-163 ℃ in onshore storage tanks or tanks with floating structures at atmospheric pressure. Liquefied Petroleum Gas (LPG) can be stored at temperatures between-50 ℃ and 0 ℃.
In the case of a floating structure, the tank may be used to transport liquefied gas and/or to receive liquefied gas for use as fuel to propel the floating structure.
A supporting and insulating wooden self-supporting tank suitable for sealing films intended to contain fluids is known, for example, from FR 2867831A, which comprises:
The bottom plate is provided with a bottom plate,
A side wall fastened to the bottom plate and protruding perpendicularly from one side of the bottom plate to define a contour of an inner space of the tank,
A cover plate supported by and fastened to the upper edge of the side wall, the cover plate being parallel to and spaced apart from the bottom plate to close the inner space of the case, the cover plate including upper and lower plates stacked and fastened to each other,
At least one slot in the cover plate, the at least one slot opening at an upper surface of the cover plate to receive a weld support intended to retain the sealing membrane on the cover plate,
At least one load-bearing baffle extending longitudinally in line with and parallel to the slot or slots, the load-bearing baffle being perpendicular to the floor and the deck, the load-bearing baffle extending between the side walls to divide the interior space into a plurality of compartments intended to receive insulation filler, the load-bearing baffle having an upper surface in contact with the lower plate of the deck and a lower surface in contact with the floor,
And a fastener vertically engaged in the upper surfaces of the lower plate and the load-supporting bulkhead to fasten the load-supporting bulkhead to the cover plate.
In FR 2867831A, the self-supporting box is used to provide a primary insulating barrier that supports a primary sealing film. The primary sealing membrane is welded to a weld support that forms a sliding connection with the anchor bar pinned in the slot. For this purpose, a longitudinal slot passes between the two rows of staples through the upper portions of the two cover plates and the underlying load-bearing partition.
The use of secondary self-supporting boxes comprising a single cover plate with a slot having a T-shaped section and intended to receive a welded support in the form of a right-angle bent flange is also known, for example, from FR 2867831A or WO 8909909A. In FR 2867831A, there is no load bearing spacer in line with the slot. In WO 8909909A, screws at the bottom of the slots are used to fasten the cover plate to the underlying load bearing bulkhead.
It is known from document FR3030014B1 to separate the covers by means of slots intended to receive welding supports. The two parts of the cover are joined together by a connecting member arranged below the two parts.
In the case of T-slots, the covers are not separated by slots because the slots do not form voids through the covers. Thus, each cover plate is a separate component. In certain large tanks that form a primary insulating barrier that supports a primary sealing membrane, the problem of cap assembly arises. In practice, the plywood forming the cover may be quite large. This makes it difficult to supply these plates to form the lid of such a box.
The present invention aims to overcome some or all of the above problems by proposing a strong self-supporting box comprising a separate lid to solve the problem of supplying plywood and to provide a primary insulating barrier in tanks that are susceptible to dynamic pressures and impacts caused by cargo sloshing.
Disclosure of Invention
To this end, the invention relates to a self-supporting tank suitable for the support and insulation of a sealing membrane intended to contain a fluid, comprising:
The base plate is provided with a bottom plate,
A side wall fastened to the bottom plate and projecting perpendicularly from one side of the bottom plate to define a contour of an interior space of the tank,
A cover plate supported by and fastened to the upper edge of the side wall, parallel to and at a distance from the bottom plate, to close the interior space of the tank, the cover plate comprising an upper surface and a lower surface,
At least one slot in the cover plate, which is open at the upper surface of the cover plate to receive a welding support intended to hold the sealing film on the cover plate,
For each slot, the box includes:
a support plate extending parallel to the cover plate, the support plate having an upper surface in contact with a lower surface of the cover plate,
A load bearing bulkhead extending longitudinally in line with and parallel to the slot, the load bearing bulkhead being perpendicular to the floor and the cover plate, the load bearing bulkhead extending between the side walls to divide the interior space into a plurality of compartments intended to receive the insulating filler, the load bearing bulkhead having an upper surface in contact with a lower surface of the support plate and a lower surface in contact with the floor,
A plurality of intermediate walls extending longitudinally on either side of the load bearing partition and perpendicular to the base plate and the cover plate, each of the plurality of intermediate walls having an upper surface in contact with a lower surface of the cover plate and a lower surface in contact with the base plate, the support plate extending between two intermediate walls adjacent the load bearing partition,
The case is characterized in that the cover plate includes:
two juxtaposed first plate portions in a first plane parallel to the bottom plate in a first connection area on the first support element,
A first fastener vertically engaged in each of the two juxtaposed first portions and the upper surface of the first support element,
The first connection region extends longitudinally in line with one of the plurality of intermediate walls, referred to as a first wall, and is parallel to the first wall, the box including a first stiffening element disposed between the slot and the first connection region in projection on at least one of the first plane and a second plane perpendicular to the first plane.
These features mean that the cover of such a main box is divided into at least two parts in a plane parallel to the bottom plate, in order to reduce the required width of the plywood sheet. The joining principle between two separate parts consists in fastening the edges of the two separate parts to a supporting element (in particular a wall), also called a thickened wall, since this supporting element is advantageously wider than the other walls which do not support the joining region. This arrangement thus enables the separate parts of the cover to be securely fastened without affecting the mechanical strength of the cover plate around the slot.
According to an embodiment, such a self-supporting box may be arranged in one or more of the following ways.
In one embodiment, the slot has a section comprising a wider bottom portion and a narrower opening portion in order in the thickness direction of the cover plate.
The cover plate further comprises a lower cover plate extending in a third plane parallel to the first plane, the lower cover plate being arranged below the two first plate portions.
In another embodiment, the lower cover plate comprises two juxtaposed second plate parts in a second joining region in a third plane, and the tank comprises a second fastener perpendicularly engaged in an upper surface of the second support element and each of the two juxtaposed second parts, the second joining region extending longitudinally in line with one of the plurality of intermediate walls, referred to as a second wall, preferably with one of the two intermediate walls adjacent the load bearing bulkhead, and parallel to the second wall, and, in projection on the second plane, the tank comprises a second stiffening element arranged between the slot and the second joining region.
The invention also relates to a sealed and thermally insulating tank for storing a fluid, the tank comprising a tank wall fastened to a load-bearing wall, wherein the tank wall comprises, from the outside to the inside of the tank in the thickness direction, a secondary insulation barrier held on the load-bearing wall, a secondary sealing film held on the secondary sealing film, a primary insulation barrier held on the secondary sealing film, and a primary sealing film held on the primary insulation barrier, characterized in that the primary insulation barrier is at least partially formed by an juxtaposed tank filled with a thermally insulating filler as described above, the primary sealing film being held on a cover plate of the tank by means of a welded support inserted in the slot.
The invention also relates to a vessel for transporting fluids, the vessel having a double hull and such tanks arranged in the double hull.
The invention also relates to a transfer system for fluids, the system comprising such a vessel, an isolation tube arranged to connect a tank on the vessel to a land or floating storage device, and a pump for driving fluid from the land or floating storage device to the tank on the vessel or from the tank on the vessel to the land or floating storage device through the isolation tube.
Finally, the invention relates to a method for loading or unloading such a vessel, wherein fluid is guided from a land or floating storage facility to a tank on the vessel or from the tank on the vessel to the land or floating storage facility through an isolation pipe.

Detailed Description
Fig. 1 is a perspective cut-away view of a wall of a sealed insulated tank in which a self-supporting box may be used.
In fig. 1 is shown the general structure of a sealed insulated tank wall 1 built in and anchored to a load bearing wall 2. The tank wall 1 may be part of a variable geometry tank, such as a polyhedral tank. Fig. 1 shows a tank wall 1 from above and shows the structure of the wall in section. Such a structure may be used with large surfaces having a variety of different orientations, for example to cover the bottom, top and side walls of a polyhedral tank. Thus, the orientation shown in fig. 1 is not limited in this respect. Conventionally, "above" refers to the location closest to the interior of the reservoir and "below" refers to the location closest to the load bearing wall 2, regardless of the orientation of the tank wall relative to the earth's gravitational field.
The tank wall 1 comprises, in its thickness, in order: a secondary insulation barrier 3 formed by juxtaposed boxes on the load bearing wall 2, the juxtaposed boxes being held on the load bearing wall 2 by a secondary holding member 4; a secondary sealing film 4 carried by the secondary insulating barrier 3; a primary insulating barrier formed by juxtaposed cases 5 held on the secondary sealing membrane 4 by a primary holding member, the juxtaposed cases themselves being fastened to the secondary holding member 4; a primary sealing membrane 6 carried by the tank 5. A secondary retaining member and a primary retaining member are described, for example, in FR 2798902A.
The primary sealing membrane 6 may be made of a high nickel content (e.g. 36%) steel (known asThe coefficient of expansion is typically between 1.2 x10 -6K-1 and 2 x10 -6K-1). Iron-manganese alloys with typical expansion coefficients of about 7 x10 - 6K-1 to 9 x10 -6K-1 may also be used. The strake 10 is sealingly welded along its raised side edges to parallel weld supports 8 which are held in slots in the cover plate 7 of the tank 5. The secondary sealing membrane 4 may be the same (as shown in fig. 1) or may be different. Reference numeral 9 denotes a slot for receiving the welded support of the secondary sealing membrane 4.
The box 5, partially visible in fig. 1, has an overall parallelepiped shape.
Fig. 2 is a side view of a self-supporting tank suitable for use in the main insulation barrier of the tank wall in fig. 1.
The cover plate 7 has a lower surface 22 and an upper surface 21. The bottom plate 23 and the cover plate 7 have a rectangular contour and are spaced apart from each other by two longitudinal end walls 27 and two lateral end walls 24, which together form the contour of the interior space of the tank 5. The interior space is divided by two load bearing webs 26 which are arranged in line with the slots 30 and possibly in line with the secondary webs 25 which may be narrower than the load bearing webs 26. The load bearing bulkhead 26 and the secondary bulkhead 25 extend longitudinally and perpendicularly to the two longitudinal end walls 27 and parallel to the two lateral end walls 24. All of these elements are suitably fastened by stapling, bolting and/or bonding. For example, the secondary separator 25 has a width of 9mm, 12mm or 15mm, and the longitudinal end wall 27 and the lateral end wall 24 may have a width of between 9mm and 24mm (e.g., 12mm or 15 mm).
In this figure, slots 30 are shown for illustration purposes. Details of the present invention are described below.
To insulate the tank 5, the compartments are filled with an insulating filler, for example expanded perlite, granular or fibrous aerogel, expanded polystyrene, glass wool, cellulose filler or a low density polymer foam (such as polyethylene, polyurethane, etc.).
The dimensions of the tank 5 may naturally differ from the example shown in fig. 2. The tank 5 may have a single load bearing bulkhead 26 and a single slot 30 in width, or conversely, more than two load bearing bulkheads 26 and more than two slots 30.
Fig. 2 also shows other possible (but not mandatory) features of the self-supporting box 5, which may be used as desired:
In order to circulate the inert gas through the primary insulating barrier, holes 28 are made in the wall 27 of the tank 5.
A vapor-permeable plug 17 made of fiberglass fabric is bonded to the inner surface of the wall 27 in front of each hole 28 to prevent leakage of the insulating filler.
The fastening studs 19, which serve as bearing surfaces for the primary holding member, are fastened against the wall 27 on the edge of the bottom plate 23.
The reinforcing members 16 perpendicular to the load bearing bulkhead 26 and the secondary bulkhead 25 extend between the walls 24 perpendicular to the floor 23. At the intersection with the load bearing bulkhead 26 and the secondary bulkhead 25, the reinforcement member has a recess designed to engage the load bearing bulkhead 26 and the secondary bulkhead 25.
The load bearing partition 26 and the slot 18 formed in the bottom plate 23 form a seat for the protruding portion of the secondary sealing membrane 4.
The elements of the self-supporting box are advantageously made of plywood. However, the composite material may be used for some or all of the self-supporting boxes. Suitable composite materials are taught, for example, in WO 2015079135A.
Fig. 3 is a cross-sectional view along a plane perpendicular to the orientation of the slot in the cover plate according to the first embodiment of the present invention. As explained above, the self-supporting tank 5 according to the invention is suitable for supporting and insulating a sealing film intended to contain a fluid. The tank 5 comprises a bottom plate 23 and side walls 24, 27 fastened to the bottom plate 23 and projecting perpendicularly from one side of the bottom plate to define the contour of the interior space of the tank 5 (these elements are shown in fig. 2).
The tank 5 comprises a cover plate 7 supported by and fastened to the upper edge of the side walls, parallel to and at a distance from the bottom plate, to close the interior space of the tank. The cover plate 7 has an upper surface 21 and a lower surface 22.
The tank 5 comprises at least one slot 30 in the cover plate, which is open in the upper surface of the cover plate to receive a welding support 8 intended to hold the sealing membrane on the cover plate 7.
Advantageously, the slot 30 has a T-shaped cross section, wherein the bottom 60 of the slot corresponds to the horizontal line of T and the opening portion 61 corresponds to the vertical line of T. As shown in fig. 3, the slot is not a through slot. In other words, the cover plates are not separated by slots.
For each slot 30, the box 5 comprises a support plate 31 extending parallel to the cover plate, the support plate 31 having an upper surface 32 in contact with a portion of the lower surface 22 of the cover plate 7. The support plate 31 is located below the slot.
The tank 5 further comprises a load-bearing partition 26 extending longitudinally in line with the slots 30 and parallel to the slots, the load-bearing partition 26 being perpendicular to the bottom plate 23 and the cover plate 7, the load-bearing partition 26 extending between said side walls 27 to divide the interior space into a plurality of compartments intended to receive a heat insulating filler (such as glass wool or perlite). The load bearing bulkhead 26 has an upper surface in contact with the lower surface of the support plate 31 and a lower surface in contact with the bottom plate.
The tank 5 includes a plurality of intermediate walls 41, 42 extending longitudinally on both sides of the load bearing partition 26 and perpendicular to the bottom plate 23 and the cover plate 7, each of the plurality of intermediate walls having an upper surface in contact with the lower surface of the cover plate and a lower surface in contact with the bottom plate 23. The support plate 31 extends between two intermediate walls 41, 42 adjacent the load bearing bulkhead 26.
According to the invention, the cover plate 7 extends in a first plane P1 parallel to the bottom plate 23 and has two juxtaposed first plate portions 33, 34 in a first connection region 35 on the support element and a first fastener 37 which engages perpendicularly in each of the two juxtaposed first portions 33, 34 and in the upper surface 38 of the support element to connect the two first portions to the support element. The support element may be a wall or a cover portion, as described below. In the embodiment shown in fig. 3, the cover plate 7 comprises two first portions 33, 34 extending in a first plane P1. The first connecting region is a region where both edges of the two portions 33, 34 come into contact with each other.
The first connection region 35 extends longitudinally in line with one of the intermediate walls, referred to as the first wall 36, and parallel to the first wall 36. In projection on at least one of the first plane P1 and the second plane P2 perpendicular to the first plane, the box comprises a first stiffening element arranged between the slot 30 and the first connection area 35.
In the embodiment shown in fig. 3, the first reinforcing element forms a first surface contact 50 with the first portion 33 of the cover plate. In the projection onto the first plane P1, the first connection region 35 (the projection of which onto the plane P1 is shown with reference numeral 51) and the slot 30 are located on both sides of the first surface contact 50 (the projection of which is shown with reference numeral 52).
In other words, the first connecting region 35 is offset relative to the slot 30 by a separation distance in the first plane P1 or the second plane P2. The separation distance refers to the distance between the first stiffening element and the first connection area 35 in projection on the first plane P1, i.e. the gap between the wall 42 and the first connection area 35. In projection on the second plane P2, the separation distance refers to the distance between the first stiffening element and the first connection region 35, i.e. the thickness of the cover portion below the slot.
The joining region is located away from the slot, i.e. in projection on the first plane P1, the slot and the joining region are separated by a non-zero distance.
Thus, the first connection region is located away from the slot. The attachment region is not directly adjacent to the slot. The intermediate wall is interposed between the load bearing bulkhead and the first wall 36 below the cover plate and above the first wall is a first connection region. In projection on the first plane P1, the first stiffening element provides support between the slot and the first connection area. This reduces the load on the cover portion around the slot. Although the juxtaposed first portions have a first attachment area, the first stiffening element helps to prevent bending of the first portions containing the slots.
It is therefore an advantage of the present invention that a box is provided in which the cover is divided into at least two parts in a plane parallel to the floor, i.e. the cover comprises smaller plywood sheets. The two separate portions are joined by fastening the edges of the two separate portions to a support element, such as a thickened wall. This arrangement thus enables the separate parts of the cover to be securely fastened, avoiding all the risks of bending of the parts containing the slots, thus ensuring the mechanical strength of the cover plate around the slots.
In the first embodiment, the cover plate 7 comprises two first portions 33, 34 extending in a first plane P1. Portion 33 contains slot 30. The two first portions 33, 34 are juxtaposed at a first connection region 35. The two juxtaposed ends of the portions 33, 34 are superposed on the support element. In this embodiment, the support element is a wall 36 arranged to contact under the first connection region 35. The first fastener 37 enables each of the two ends of the first portion 33, 34 to be connected to the upper surface 38 of the support element.
Preferably, the first fastener 37 is a staple. Alternatively, the fastener may be any other fastening means, such as a screw or nail. The fasteners may also be adhesive dots that fasten the ends of the portions 33, 34 to the respective support elements.
In this embodiment, the first stiffening element is an intermediate wall 42 and forms a first surface contact 50 with a portion of the cover plate. In projection on the first plane P1, the first connection region 35 and the slot 30 are located on both sides of the projection 52 of the first surface contact 50. The first surface contact 50 is a flat support between the slot and the first connection region against the lower surface of the portion 33. The flat support helps to hold the portion 33 in place and helps to prevent the portion from bending.
As a non-limiting example, the first wall 36 (also referred to as a thickened wall) may have a width of 21mm and the intermediate wall may have a thickness of 9 mm. The bottom 60 of the slot may have a width generally between 20mm and 30 mm.
The cover portion may have a thickness typically between 12mm and 15 mm. The dimensions of the cover plate are typically about 1m by 1.2m. The present invention enables these dimensions to be reduced. Instead of requiring a large cover plate, two smaller plate portions may be used to form the cover plate. The invention also enables larger boxes to be built. In practice, on the basis of sheets with a maximum dimension of 1.3m by 1.5m, it is possible to manufacture larger lids (for example, to obtain lids with dimensions of 1.4m by 1.4 m) by separating said lids according to the principles of the invention.
Advantageously, the midline of the bottom portion 60 of the slot is positioned in line with the midplane of the load bearing bulkhead 26.
Advantageously, the fasteners 37 are arranged on both sides of the median plane of the wall 36.
The load bearing bulkheads 26 may be made of wood, plywood, or composite materials.
Fig. 4 is a cross-sectional view along the same plane according to a second embodiment of the present invention. In this embodiment, all elements are identical to those of the first embodiment shown in fig. 3. In this embodiment, the cover plate 7 further comprises a lower cover plate 40 extending in a third plane P3 parallel to the first plane P1. The lower cover plate 40 is arranged below the two first plate portions 33, 34. A first fastener 37 engages vertically in each of the two juxtaposed first portions 33, 34 and the upper surface 38 of the support element to connect the two first portions to the support element. In this embodiment, the support element is a lower plate 40.
Thus, in this embodiment, the cover plate has two cover layers: a lower plate 40 extending in plane P3 and an upper plate extending in plane P1, the upper plate comprising the two first portions 33, 34 described above.
The two cover layers stiffen the cover plate by doubling the total thickness of the cover plate without requiring an excessively thick plate portion in the case of a single cover layer.
Fig. 5 is a cross-sectional view along the same plane according to a third embodiment of the present invention.
In this embodiment, the cover plate 7 comprises an upper cover plate 41 extending parallel to the first plane P1 and two portions 33, 34 extending in the plane P1. An upper cover plate 41 is arranged on the two first plate portions 33, 34 and contains the slot 30. As specified above, the two cover layers strengthen the cover plate.
The two first portions 33, 34 are juxtaposed at a first connection region 35. The two juxtaposed ends of the portions 33, 34 are superposed on the support element. In this embodiment, the support element is an intermediate wall 42 (also referred to as first wall 36) arranged to contact below the first connection region 35. The first fastener 37 enables each of the two ends of the first portions 33, 34 to be connected to the upper surface 38 of the wall 42. The wall 42 is thicker than in the embodiment of fig. 4 to enable the two portions 33, 34 to be connected with the fastener 37.
In the projection onto the second plane P2, the first connection region 35 (the projection of which onto the plane P2 is shown with reference numeral 51 ') and the slot 30 are located on both sides of a first surface contact 50' (the projection of which is shown with reference numeral 52 '). In projection on the second plane P2, the combination of the offset of the joining region 35 with respect to the plane P1 and the gap between the joining region and the plane P2 forms a first stiffening element. This arrangement provides support between the slot and the first attachment region. Similar to the foregoing, the load on the cover portion around the slot is reduced. Even if the cover plate has a lower plate that is divided into two juxtaposed portions around the joining region, the size of the gap between the joining region and the slot (as thick as the plate portion in the embodiment of fig. 5, or as wide as the tank bulkhead distance (also referred to as the gap between the two tank bulkhead distances)) prevents the first portion containing the slot from bending. This ensures that the cover plate as a whole has very good mechanical strength.
Fig. 6 is a cross-sectional view along the same plane according to a fourth embodiment of the present invention. In this embodiment, all elements are identical to those of the first embodiment shown in fig. 4. In the embodiment shown in fig. 6, the lower plate of the cover plate 7 has two juxtaposed second plate parts 33', 34' in the third plane P3, which are connected to the wall 42 in a second joining region 35 'by means of second fasteners 37'. The lower plate, the two second portions 33', 34' and the second joining region 35' are identical to the lower plate, the two first portions 33, 34 and the first joining region 35, respectively, in the embodiment of fig. 5.
In other words, the second fastener 37' engages perpendicularly in each of the two juxtaposed second portions 33', 34' and the upper surface 38 of the second support element. The second joining region 35' extends longitudinally in line with one of the intermediate walls, referred to as the second wall 36, preferably one of the two intermediate walls adjacent the load bearing bulkhead 26, and parallel to the second wall 36. In projection on the second plane P2, the box comprises a second stiffening element arranged between the slot 30 and the second joining zone 35'.
Thanks to these features, the cover plate 7 has two cover layers which stiffen the cover plate by doubling the thickness of the cover plate, the cover plate comprising smaller plate portions 33, 34, 33', 34'.
Instead of plywood, composite materials can be used to make all or part of the self-supporting box. Suitable composite materials are taught, for example, in WO 2015079135A.
The tank 5 described above may be used to build up a primary insulating barrier in the entire tank or only in certain parts of the tank. For example, the tank 5 described above may be used near the edges of the tank and other insulating blocks in other parts of the tank wall. Such an arrangement is described for example in WO 2019077253A.
In fig. 7, a cross-sectional view of a lng carrier 70 shows a hermetically sealed tank 71 having an overall prismatic shape installed in a double hull 72 of the ship. The wall of tank 71 has a primary sealing barrier designed to be in contact with the liquefied gas contained in the tank, a secondary sealing barrier arranged between the primary sealing barrier and the double hull 72 of the vessel, and two insulating 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 simplified variant, the vessel has a single hull.
In a known manner, a loading/unloading pipe 73 arranged on the upper deck of the vessel may be connected to a marine or port terminal using a suitable connector to transfer liquefied gas cargo to or from the tank 71.
Fig. 7 shows an example of a marine terminal comprising a loading/unloading point 75, an underwater pipeline 76 and land equipment 77. The loading/unloading point 75 is a fixed offshore unit comprising a movable arm 74 and a column 78 holding the movable arm 74. The movable arm 74 carries a bundle of isolation hoses 79 that can be connected to the load/unload tube 73. The orientable movable arm 74 may be adapted for use with all sizes of lng carriers. A connecting conduit (not shown) extends within the column 78. The loading/unloading point 75 enables loading and unloading from the lng carrier 70 to the land facility 77 or from the land facility to the lng carrier. The apparatus has a liquefied gas storage tank 80 and a connecting pipe 81 connected to the loading/unloading point 75 via a submarine pipeline 76. The underwater piping 76 enables the transportation of liquefied gas between the loading/unloading point 75 and the onshore facility 77 over a long distance (e.g., 5 km), which enables the lng carrier 70 to remain long distance off shore during loading and unloading operations.
To generate the pressure required for transporting the liquefied gas, pumps carried on the vessel 70 and/or mounted at the land equipment 77 and/or mounted at the loading/unloading point 75 are used.
