Description

SUPPORT APPARATUS

FIELD OF INVENTION

The present invention relates to a support apparatus, for example, for use with at least one expandable or movable element for locating a first and second structure or member relative to one another. The present invention also relates to an associated system, arrangement and method. The apparatus, system, arrangement and/or method may find utility offshore and/or in a marine environment.

BACKGROUND TO INVENTION

Offshore structures, such as offshore wind turbines, may be supported and/or mounted by a support structure, such as for example a jacket or monopile. The jacket may typically have three or four legs, which may be arranged to form a lattice structure. Jackets can be lowered onto pre-installed piles. The piles may be installed by driving them into the seabed using a piling hammer and/or a piling template.

Once the jacket has been lowered onto the piles, the jacket may be permanently fixed to the piles, for example, by forming a cemented or grouted connection between the jacket and the piles. The cemented or grouted connection may transfer the loads between the jacket and the piles.

It is desirable to minimise or prevent any movement between the jacket and piles, until the cement is fully cured so as to form a strong and robust connection between the jacket and the piles. This is often achieved by waiting for sufficiently calm weather conditions, which may lead to increased costs for installing the jackets on the piles.

Subsea packers and/or grippers may be used in the offshore industry for securing a support structure to a foundation, such as securing the jacket to the pile. Such packers and/or grippers may be subject to extreme forces during installation. That is, forces -such as shearing forces -may occur due to relative movement of the jacket and the pile during installation. Such forces may damage the packers and/or grippers, or be otherwise detrimental to a packing, gripping, supporting, lifting, stabilizing, positioning or centralizing force applied by the packer or grippers.

Furthermore, such packers and/or grippers may be complex devices with multiple moving or configurable components and parts, and thus may be prone to damage during installation between a jacket or pile, thus impacting upon the reliability and/or efficiency of such packers and/or grippers.

It is an object of at least one embodiment of at least one aspect of the present invention to obviate or at least mitigate one or more problems or disadvantages in the prior art.

It is an object of at least one embodiment of at least one aspect of the present invention to provide a more practical and/or commercially effective apparatus, system and/or associated method for locating a first structure or member and a second structure or member relative to one another than described in the prior art.

DETAILED DESCRIPTION OF DRAWINGS

Referring to Figure 1, there is shown a perspective view of a structure 10 installed on foundations 20a, 20b, 20c. In the example shown, the structure 10 is a jacket for a wind turbine (not shown), e.g. an offshore wind turbine. The foundations 20a, 20b, 20c are piles, which may be located offshore.

During installation of the structure 10 onto the foundations 20a, 20b, 20c, it is desirable to minimise or prevent any movement between the structure 10 relative to the foundations 20a, 20b, 20c, until the structure 10 is permanently fixed to the foundations 20a, 20b, 20c, such as by cement or otherwise.

In an example use case, the present invention finds utility in supporting the structure 10 relative to one or more foundations 20a, 20b, 20c and/or supporting an expandable element relative to the structure 10 and/or the one or more foundations 20a, 20b, 20c during such installation.

Referring to Figure 2a there is shown an example of an expandable element, generally denoted 50 in an unexpanded configuration. For purposes of example only, the expandable element 50 is shown without a support apparatus. That is, Figure 2a is for purposes of showing an expandable 50 element and associated features, and Figure 2 does not embody the support apparatus of the present invention.

The expandable element 50 comprises a plurality of inflatable elements 55a, 55b, 55c, 55d.

Each inflatable element 55a, 55b, 55c, 55d may comprise or be made or formed from a sheet metal material. Additionally, or alternatively, each inflatable element 55a, 55b, 55c, 55d may be coated and/or infused with a metal or metal alloy.

Each inflatable element 55a, 55b, 55c, 55d comprises a plurality of corners and each corner may comprise a concave portion 60a, 60b, 60c, 60d. In some examples, a periphery of each inflatable element 55a, 55b, 55c, 55d may correspond to a substantially rectangular shape with concave cut-away portions at each corner.

In the example shown, the expandable element 50 comprises four inflatable elements 55a, 55b, 55c, 55d. It will be appreciated that in other examples the expandable element 50 may comprise fewer than or greater than four inflatable elements 55a, 55b, 55c, 55d.

The plurality of inflatable elements 55a, 55b, 55c, 55d are shown arranged in a stack. As such, a stroke of the expandable element 50, e.g. a total distance covered between exterior faces of the expandable element 50 between an unexpanded and expanded configuration, may be selected based at least in part upon one or more of: a quantity of inflatable elements 55a, 55b, 55c, 55d; dimensions of one or more of the inflatable elements; and/or a degree of expansion, e.g. inflation, of each inflatable element 55a, 55b, 55c, 55d.

Each inflatable element 55a, 55b, 55c, 55d comprises an associated inlet 70a, 70b, 70c, 70d. Each inlet 70a, 70b, 70c, 70d is disposed at a perimeter of a face or plate of an inflatable element 55a, 55b, 55c, 55d. Each inlet 70a, 70b, 70c, 70d is adapted for coupling to a line 65a, 65b, 65c, 65d, such as a hydraulic line. The inlets 70a, 70b, 70c, 70d may be adapted for supplying fluid, such as a pressurised fluid, to the inflatable elements 55a, 55b, 55c, 55d.

The expandable element 50 is mounted on a structure 75.

The structure 75 comprises a plurality of centralisers or supports 80a, 80b, 80c. The supports or centralisers 80a, 80b, 80c are arranged on an outer surface of the structure 75.

The expandable element 50 is disposed between a pair of centralisers or supports 80a, 80c. Furthermore, the expandable element 50 is seated on a centraliser or support 80b. That is, in the example shown, the centralisers or supports 80a, 80b, 80c are arranged in a substantially V-shaped configuration for supporting the expandable element 50 therebetween.

Referring to Figure 2b there is shown the expandable element 50 of Figure 2a in an expanded configuration. That is, each of the inflatable elements 55a, 55b, 55c, 55d is inflated. As such, the expandable element 50 extends across a gap, e.g. an annulus, between the structure 75 and a further structure 85. By pressurizing the expandable element 50, a stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning force may be applied by the expandable element 50 to the structure 75 and to the further structure 85.

Referring to Figure 3 there is shown a perspective view of a plurality of expandable elements 150a, 150b mounted on a structure 175. In the example shown the structure 175 is a leg of a jacket for a wind turbine (only a portion of the leg is shown).

The expandable elements 150a, 150b are disposed in an annulus 190 between the structure 175 and a further structure 185. In the example shown the further structure 185 is a foundation, e.g. a pile. For purposes of illustration, a portion of the further structure 185 is cut away to expose the expandable elements 150a, 150b.

The expandable elements 150a, 150b are shown in an unexpanded configuration in Figure 3. Also shown is a support apparatus 200a, 200b associated with each expandable element 150a, 150b. The support apparatuses 200a, 200b are described in more detail with reference to Figures 4a to 4c.

Each support apparatus 200a, 200b is mounted on the structure 175. As will be described below, each support apparatus 200a, 200b may be mounted using bolts, welding or the like. In the example shown in Figure 3, each support apparatus 200a, 200b is mounted to the structure 175 using a pair of brackets 195a, 195b. Furthermore, in some example embodiments, the support apparatuses 200a, 200b and/or the brackets 195a, 195b may be supported by associated supports or centralizers 110a, 110b.

Referring to Figure 4a there is shown a schematic diagram of a top view of a support apparatus, generally denoted 300, according to an embodiment of the invention. The support apparatus 300 is mounted on a first structure 375, which for purposes of example may be a jacket for a wind turbine.

The support apparatus 300 is shown in a first configuration. The first configuration is a stowed configuration. In use, the stowed configuration may be suitable for jacket installation and/or pile entry, e.g. positioning of the first structure 375 and a second structure 385 relative to one another such as during an initial stage of installation.

Also shown is an expandable element 350. The expandable element 350 may be an expandable element 50 as described with reference to Figures 2a and 2b above.

Also shown is the second structure 385, which for purposes of example may be a foundation or pile, such as foundation 20a, 20b, 20c shown in Figure 1, structure 75 shown in Figures 2a and 2b, or structure 175 as shown in Figure 3.

The support apparatus 300 and expandable element 350 is shown disposed in a gap, e.g. an annulus, between first structure 375 and the second structure 385.

The support apparatus 300 comprises a first planar member 310. The support apparatus 300 comprises a second planar member 320. As will be described, the first planar member 310 and second planar member 320 are configurable between a first configuration as shown in Figure 4a and a second configuration as shown in Figure 4c by expansion of the expandable element 350.

In the example embodiment of Figure 4a, the expandable element 350 forms a substantially curved shape when in the first configuration. That is, the expandable element 350 comprises a plurality of substantially straight portions 320a, 320b, 320c that collectively form a substantially curved or angled expandable element 350, such that a shape of the expandable element 350 substantially conforms to a shape of the structure 375 upon which the expandable element 350 is mounted.

That is, each substantially straight portion 320a, 320b, 320c of the expandable element 350 is inclined at an angle relative to an adjacent substantially straight portion 320a, 320b, 320c. In one example embodiment, an angle of inclination between adjacent straight portions 320a, 320b, 320cmay typically be in the range of 4 to 8 degrees, but may be more or less, depending in particular on a radius of an annular void between the first structure 375 and the second structure 385 into which the expandable element 350 may be disposed in use.

Similarly, the support apparatus 300 may forms a substantially curved shape when in the first configuration, such that the support apparatus 300 conforms to a shape of the expandable element 350 and/or an annular void between the first structure 375 and the second structure 385 into which the support apparatus 300 may be disposed in use.

As shown in Figure 4a, in the first configuration the first planar member 310 and the second planar member 320 are configured to protect, e.g. shield, the expandable element 350. Advantageously, the expandable element 350 is protected from damage during installation of the first or second structure 375, 385 on or around the other of the first or second structure 385, 375.

That is, in the first configuration the first planar member 310 and the second planar member 320 hold the expandable element 350 against the first structure 375 such that the expandable element 350 and the first planar member 310 and the second planar member 320 do not stand proud, e.g. extend beyond and extent of, at least one centraliser or support 330.

In the first configuration the first planar members 310 and the second planar member 320 partly overlap. In other example embodiments, such as embodiment with larger expandable elements 350 and/or smaller or shorted planar members 310, 320, the first planar member 310 and the second planar member 320 may not overlap. Furthermore, in other embodiments (not shown), in the first configuration the first and second planar members 310, 320 may at least partly interleave, e.g. comprise interleaving fingers or the like.

At least one of the first planar member 310 and second planar member 320 may comprise a hinge. At least one of the first planar member 310 and the second planar member 320 may be adapted to bend and/or deform at, about or around a predefined point. That is, a portion of the first and/or second planar members 310, 320 may be adapted to preferentially bend or deform when the first and/or second planar members 310, 320 are subjected to bending or deforming forces or stresses. For example, the first planar member 310 and second planar member 320 may comprise a living hinge. In the example embodiment shown, the first planar member 310 comprises a bend 340a, about which the first planar member 310 may preferentially deform or bend when subject to forces, as will be described with reference to Figures 4b and 4c.

Similarly, in the example embodiment shown, the second planar member 320 comprises a bend 340b, about which the second planar member 320 may preferentially deform or bend when subject to forces, as will be described with reference to Figures 4b and 4c.

The first and second planar members 310, 320 are coupled to the first structure 375. In the example shown, the first planar member 310 is coupled to the structure 375 by a bracket 395a. Similarly, the second planar member 320 is coupled to the structure 375 by a bracket 395b. Each bracket 395a, 395b is bolted to the structure 375.

It will be appreciated that in other embodiments, the brackets 395a, 395b may be additionally or altematively welded, fused or otherwise adhered to the structure 375. In yet further embodiments, the first and second planar members 310, 320 may be directly coupled to the structure 375, e.g. without brackets 395a, 395b.

It will also be appreciated that for purposes of example only, the support apparatus 300 and associated expandable element 350 are shown mounted on the first structure 375, and that in other embodiments the support apparatus 300 and associated expandable element 350 may alternatively be mounted on the second structure 385. Referring to Figure 4b there is shown a schematic diagram of a top view of the support apparatus 300 of Figure 4a in an intermediate configuration between the first configuration and a second configuration.

The expandable element 350 is shown in a partially expanded, e.g. inflated, configuration.

Partial expansion of the expandable element 350 causes the first planar member 310 to tend towards a configuration, e.g. to be partially transifioned as shown in Figure 4b, between the first configuration and the second configuration. That is, the expandable element 350 exerts a force upon the first planar member 310, causing bending and/or deformation of the first planar member 310. Preferably at least an initial deformation the first planar member 310 occurs substantially at bend 340a, as shown in Figure 4b. The first planar member 310 is configurable to act upon the second planar member 320 to at least partially transition the second planar member 320 between the first configuration and the second configuration.

That is, the first planar member 310 exerts a force upon the second planar member 320, causing bending and/or deformation of the second planar member 320. Preferably at least an initial deformation the second planar member 320 occurs substantially at bend 340b, as shown in Figure 4b.

Referring to Figure 4c there is shown a schematic diagram of a top view of the support apparatus 300 of Figure 4a in the second configuration.

In the second configuration the expandable member 350 is expanded, e.g. inflated, to fill a gap such as an annulus between the first structure 375 and the second structure 385. As such, in the second configuration, the expandable member 350 may provide a stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning force to the first and second structures 375, 385.

In some embodiments, one or more inflatable elements of the expandable member 350 may be inflated to pressures in the region of 100 bar. Such inflation may be carried out from surface, e.g. from a jacket or a support vessel, using an umbilical or the like.

In the second configuration the first planar member 310 and the second planar member 320 are configured to support the first structure 375 relative to the second structure 385.

That is, in the second configuration the support apparatus 300 provides support e.g. stabilizing or centralizing support or the like, between the first and second structures 375, 385 in addition to a support provided by the expandable element 350. Furthermore, in the second configuration the support apparatus 300 is also configured to support the expandable element 350, e.g. limit any effects of forces such as shearing forces caused by movement of the first structure 375 relative to the second structure 385, upon the expandable element 350.

In the second configuration a portion 360a of the first planar member 310 is deformed to conform to a shape of a portion of the expandable element 350. Similarly, in the second configuration a portion 360b of the second planar member 320 is deformed to conform to a shape of a portion of the expandable element 350 In the example embodiment shown in Figure 4c, in the second configuration a portion 365a of the first planar member 310 is disposed, e.g. extends, between the expandable element 350 and the second structure 385. Similarly, a portion 365b of the second planar member 320 is disposed, e.g. extends, between the expandable element 350 and the second structure 385. It will be appreciated that in other embodiments falling within the scope of the present invention, in the second configuration the first and/or second planar members 310, 320 may not have portions that are disposed between the expandable element 350 and the second structure 385.

Referring to Figure 5a there is shown a photograph of a support apparatus 400 according to an embodiment of the present invention, on a test rig 430. An expandable element 450 comprising a single inflatable element and a support apparatus 400 comprising a first planar member 410 and a second planar member 420 are disposed between a first plate 475 of the test rig 430 and a second plate 485 of the test rig 430. In Figure 5a, the expandable element 450 has been expanded. As such, the support apparatus 400 is configured into a second configuration by the expansion of the expandable element 450.

In Figure 5b, the second plate 485 of the test rig 430 has been removed to expose the support apparatus 400 for purposes of inspection. It can be seen that the second planar member 420 has deformed to conform to a shape of the expandable element 450 and the second plate 420.

In the example embodiment shown in Figures 5a and 5b, the first and second planar members 410, 420 comprise metal sheets. In a preferred embodiment, the first and second planar members 410, 420 are formed from steel.

Referring to Figure 6a there is shown a photograph of a support apparatus 500 according to an embodiment of the invention in a test rig 530 in a first configuration.

In the embodiment shown, the first and second planar members 510, 520 of the support apparatus 500 comprise meshes. It will be appreciated that in other embodiments falling within the scope of the present invention, the first and second planar members 510, 520 of the support apparatus 500 may comprise plates, sheets, meshes, lattices, or the like, or any combination thereof For purposes of testing, the expandable element has been represented by a movable element 550. Referring to Figure 6b-d there is shown a sequential series of photographs of the support apparatus 500 of Figure 6a in intermediate configurations between the first configuration and a second configuration.

It can be seen, in particular in Figure 6b, that as the support apparatus 500 transitions from the first configuration to the second configuration, the first member 510 initially acts upon the second member 520 to bend and/or deform the second member 520. As can be seen, in particular for Figures Sc and 6d, the movable element 550 also acts upon both of the first and second members 510, 520 to bend and/or deform the first and second members 510, 520.

Referring to Figure 6e there is shown a photograph of the support apparatus 500 of Figure 6a in the second configuration. In the second configuration the movable member 550 is moved, e.g. raised, such that a portion 560a of the first planar member 510 is deformed to conform to a shape of a portion of the movable element 550. Similarly, in the second configuration a portion 560b of the second planar member 520 is deformed to conform to a shape of a portion of the expandable element 550 In the example embodiment shown in Figure 6e, in the second configuration a portion 565a of the first planar member 610 is disposed, e.g. extends, between the movable element 550 and a frame of the test rig 530. Similarly, a portion 565b of the second planar member 520 is disposed, e.g. extends, between the movable element 550 and frame of the test rig 530. It will be appreciated that in other embodiments falling within the scope of the present invention, in the second configuration the first and/or second planar members 510, 520 may not have portions that do not extend between the movable element 550 and the frame of the test rig 530.

In use, the support apparatus 200a, 200b, 300, 400,500 may be abandoned, e.g. left in situ, after stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning a first structure relative to a second structure. In particular, the support apparatus 200a, 200b, 300, 400, 500 may be abandoned, e.g. left in situ, after a gap between the first and second structures is cemented, or otherwise at least partially filled.

Referring to Figure 7a there is shown a schematic diagram of a top view of a support apparatus, generally denoted 600, according to a further embodiment of the invention in a first configuration. The support apparatus 600 is mounted on a first structure 675, which for purposes of example may be a jacket for a wind turbine.

The support apparatus 600 is shown in a first configuration. The first configuration is a stowed configuration. In use, the stowed configuration may be suitable for jacket installation and/or pile entry, e.g. positioning of the first structure 675 and a second structure 685 relative to one another such as during an initial stage of installation.

Also shown is an expandable element 650. The expandable element 650 may be an expandable element 50 as described with reference to Figures 2a and 2b above. Also shown is the second structure 685, which for purposes of example may be a foundation or pile, such as foundation 20a, 20b, 20c shown in Figure 1, structure 75 shown in Figures 2a and 2b, or structure 175 as shown in Figure 3.

The support apparatus 600 and expandable element 650 is shown disposed in a gap, e.g. an annulus, between first structure 675 and the second structure 685.

The support apparatus 600 comprises a first planar member 610 and two second planar members 620a, 620b. In the example embodiment of Figure 7a, the first planar member 610 and two second planar members 620a, 620b are formed as a monolithic structure, e.g. a metal sheet with folds at fold points 685a, 685b. As such, planar members 610, 620a, 620b are formed from a single planar member folded to form an expandable and/or collapsible support apparatus 600. That is, the second planar members 620a, 620b are configurable to bend or move relative to the first planar member 610 as the support apparatus 600 is transitioned between the first configuration and the second configuration, as will be described in more detail with reference to Figure 7b. As will be described, the first planar member 610 and second planar members 620a, 620b are configurable between a first configuration as shown in Figure 7a and a second configuration as shown in Figure 7b by expansion of the expandable element 650.

In the example embodiment of Figure 7a, the expandable element 650 forms a substantially curved shape when in the first configuration. That is, the expandable element 350 comprises a plurality of substantially straight portions 635a, 635b, 635c that collectively form a substantially curved or angled expandable element 650, such that a shape of the expandable element 650 substantially conforms to a shape of the structure 675 upon which the expandable element 650 is mounted.

That is, each substantially straight portion 635a, 635b, 635c of the expandable element 650 is inclined at an angle relative to an adjacent substantially straight portion 635a, 635b, 635c. In one example embodiment, an angle of inclination between adjacent straight portions 635a, 635b, 635c may typically be in the range of 4 to 8 degrees, but may be more or less, for example depending in particular on a radius of an annular void between the first structure 675 and the second structure 685 into which the expandable element 650 may be disposed in use.

Similarly, the support apparatus 600 may forms a substantially curved shape when in the first configuration, such that the support apparatus 600 conforms to a shape of the expandable element 650 and/or an annular void between the first structure 675 and the second structure 685 into which the support apparatus 600 may be disposed in use.

In the example embodiment of Figure 7a, the first planar member 610 comprises a plurality of substantially straight portions 625a, 625b, 625c that collectively form a substantially curved or angled planar member 620, such that a shape of the planar member 620 substantially conforms to a shape of the structure 675 and/or the expandable element 650. It will be appreciated that in other embodiments, the planar member 620 may be curved and/or comprise curved portions In yet further embodiments, the planar member 620 may be substantially straight.

As shown in Figure 4a, in the first configuration the first planar member 610 is configured to protect, e.g. shield, the expandable element 650. Advantageously, the expandable element 650 is protected from damage during installation of the first or second structure 675, 685 on or around the other of the first or second structure 685, 675.

That is, in the first configuration the first planar member 610 and/or the second planar members 620a, 620b hold the expandable element 650 against the first structure 675 such that the expandable element 650 and the first planar member 610 and the second planar members 620a, 620b do not stand proud, e.g. extend beyond and extent of, at least one centraliser or support 630.

Furthermore, support apparatus 600 partially encloses the expandable element 650. That is, the first planar member 610 and the second planar members 620a, 620b are configured to at least partially enclose, e.g. surround and/or envelop, the expandable element 650 In a similar manner to that of the embodiment of Figures 4a to 4c, the second planar members 620a, 620b may comprise a hinge (not shown) at, or near to, points 640a, 640b where the second planar members 620a, 620b are coupled to the first structure 675. That is, the second planar members 620a, 620b may be adapted to bend and/or deform, e.g. preferentially bend or deform, at about or around predefined points 640a, 640b when subjected to bending or deforming forces or stresses. In other embodiments, such as that shown in Figure 7a, no hinge is implemented at the points 640a, 640b where the second planar members 620a, 620b are coupled to the first structure 675.

The second planar members 620a, 620b are coupled to the first structure 375. The second planar members 620a, 620b may be coupled to the first structure 375 by at least one of welding, bolts, or the like.

It will also be appreciated that for purposes of example only, the support apparatus 600 and associated expandable element 650 are shown mounted on the first structure 675, and that in other embodiments the support apparatus 600 and associated expandable element 650 may alternatively be mounted on the second structure 685.

Turning now to Figure 7b, there is shown a schematic diagram of a top view of the support apparatus of Figure 7a in the second configuration.

In the second configuration the expandable member 650 is expanded, e.g. inflated, to fill a gap such as an annulus between the first structure 675 and the second structure 685. As such, in the second configuration, the expandable member 650 may provide a stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning force to the first and second structures 675, 385.

In the second configuration the first planar member 610 and the second planar members 620a, 620b are configured to support the first structure 675 relative to the second structure 685. That is, in the second configuration the support apparatus 600 provides support e.g. stabilizing or centralizing support or the like, between the first and second structures 675, 685 in addition to a support provided by the expandable element 350.

Furthermore, in the second configuration the support apparatus 600 is also configured to support the expandable element 650, e.g. limit any effects of forces such as shearing forces caused by movement of the first structure 675 relative to the second structure 685, upon the expandable element 650.

In the example embodiment shown in Figure 7b, in the second configuration a portion 665 of the first planar member 610 is disposed, e.g. extends, between the expandable element 650 and the second structure 685. That is, in the second configuration the support apparatus 600 partially encloses the expandable element 650.

That is, the first planar member 610 and the second planar members 620a, 620b are configured to at least partially enclose, e.g. surround and/or envelop, the expandable element 650.

As the expandable element 650 is expanded between the first configuration shown in Figure 7a to the second configuration shown in Figure 7b, the planar members 610, 620a, 620b bend or deform, in particular at fold points 685a, 685b, That is, the support apparatus 600 is configured to expand, in particular by deforming at predefined points, to accommodate the expansion of the expandable element 650.

Referring to Figure 8a there is shown a schematic diagram of a top view of a support apparatus, generally denoted 700, according to a further embodiment of the invention in a first configuration. The support apparatus 700 has generally similar features to that of the support apparatus 600 of Figure 7a, and as such all features of the embodiment of Figure 8a are not described in extensive detail.

In the embodiment of Figure 8a, the support apparatus 600 comprises a first planar member 610 and two second planar members 620a, 620b. In the example embodiment of Figure 8a, the first planar member 610 and two second planar members 620a, 620b are formed as a separate, e.g. separate metal sheets, with connections provided at hinge points 785a, 785b. The first planar member 610 may be coupled to the second planar members 720a, 720b by at least one of: one or more welds; a mechanical hinge; a living hinge; a fold; a perforation; one or more bolts, screws, fasteners, clips or pins.

The second planar members 720a, 720b are coupled to the first structure 775. The second planar members 720a, 720b may be coupled to the first structure 375 by at least one of welding, bolts, or the like.

In the example shown in Figure 8b, the second planar members 720a, 720bare coupled to the structure 775 by brackets 795a, 795b. It will be appreciated that in other embodiments, the brackets 795a, 795b may be additionally or alternatively welded, fused or otherwise adhered to the structure 775. In yet further embodiments, the second planar members 620a, 620b may be directly coupled to the structure 775, e.g. without brackets 795a, 795b.

Turning now to Figure 8b, there is shown a schematic diagram of a top view of the support apparatus of Figure 8a in the second configuration.

In the second configuration the expandable member 750 is expanded, e.g. inflated, to fill a gap such as an annulus between the first structure 775 and the second structure 785. As such, in the second configuration, the expandable member 750 may provide a stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning force to the first and second structures 775, 385.

In the second configuration the first planar member 710 and the second planar members 720a, 720b are configured to support the first structure 775 relative to the second structure 785. That is, in the second configuration the support apparatus 700 provides support e.g. stabilizing or centralizing support or the like, between the first and second structures 775, 785 in addition to a support provided by the expandable element 350 As the expandable element 850 is expanded between the first configuration shown in Figure 8a to the second configuration shown in Figure 8b, the planar members 710, 720a, 720b may pivot relative to each other, or deform or ben in a controlled manner due to hinge points 785a, 785b, That is, the support apparatus 700 is configured to expand, in particular by deforming or hinging at predefined points, to accommodate the expansion of the expandable element 750.

Referring to Figure 9a there is shown a schematic diagram of a top view of a support apparatus, generally denoted 800, according to a further embodiment of the invention in a first configuration.

Notably, in the example embodiment of Figure 9a, an expandable element 850 forms a substantially curved shape when in the first configuration. Similarly, the support apparatus 800 may forms a substantially curved shape when in the first configuration, such that the support apparatus 800 conforms to a shape of the expandable element 850 and/or an annular void between the first structure 875 and the second structure 885 into which the support apparatus 800 may be disposed in use.

A dashed line 815 shows a disposition/location/arrangement of the support apparatus 800 in a second configuration.

Figure 9b show the support apparatus 800 of Figure 9a in isolation. The support apparatus 800 comprises a first planar member 810 and second planar members 820a, 820b.

Referring now to Figures 10a to 10d, Figure 10a depicts a perspective view of an arrangement comprising a plurality of support apparatuses 1000 according to a yet further embodiment of the present invention in a first configuration. In the first configuration an expandable member 1050 associated with each support apparatus 1000 is in a stowed configuration suitable for jacket installation and/or pile entry. That is, in the first configuration each expandable member 1050 is unexpanded.

In the embodiment of Figures 10a to 10d, the expandable members 1050 are configurable to be transifioned between the first, unexpanded state and a second expanded state, and subsequently back to the/an unexpanded state. The subsequent unexpanded state may correspond to the first state, or to a third state, as described in more detail below with reference to Figures 10b to 10d.

Referring again to Figure 10a, each support apparatus 1000 is mounted on a first structure 1075, which for purposes of example may be a jacket for a wind turbine.

Also shown is a second structure 1085, which for purposes of example may be a foundation or pile, such as foundation 20a, 20b, 20c shown in Figure 1.

The second structure 1085 is depicted as semi-transparent to show the location of the support structures 1000 disposed in an annular gap between the first structure 1075 and the second structure 1085.

Also depicted in Figure 10a is a collar member 1095. The collar member 1095 extends around an outer surface of the first structure 1075. In some embodiments, each support apparatus 1000 may be coupled to the collar member 1095. In some embodiments, each support apparatus 1000 may be held in place by the collar member 1095.

In the example embodiment of Figure 10a, each support apparatus 1000 is coupled to an associated frame 1065. Each frame 1065 may hold its associated support apparatus 1000 in situ within the annular gap when the associated support apparatus 1000 is in a first configuration, e.g. an unexpended configuration, as described below in more detail.

Each frame 1065 is provided with a limiting member 1055, for limiting an extent to which each frame 1065 may extend into the second structure 1085, e.g. an extent to which each frame 1065 may be inserted into the second structure 1085. In some embodiments, such limiting members 1055 may help position the first structure 1075 relative to the second structure 1085, and thus ensure each associated support apparatus 1000 is correctly positioned within the annular gap.

In the example embodiment of Figure 10a, the collar member 1095 is configured to hold each frame 1065 in place. That is, an upper surface of each frame 1065 is configured to abut the collar member 1095 and the limiting member 1055 associated with each frame abuts the second structure 1085, e.g. an upper surface, edge or rim of the second structure 1085, such that the/each frame 1065 is restricted from movement relative to the first structure 1075 and second structure 1085.

The collar member 1095 may be provided as a strap, a deformable plate, a metal sheet, or the like. The collar member 1095 may be fastened using one or more adjustable fastening elements 1045, such as adjustable tension latches or the like. As such, the collar member and thus also each support apparatus 1000 may be fixedly coupled to the first structure 1075.

It will be appreciated that in other embodiments, each support apparatus 1000 may be otherwise coupled to the first structure 1075, such as by welding, adhesion, bolting, or the like. That is, in some embodiments the collar member 1095 may not be employed.

Each support apparatus 1000 is also supported by at least one support or centraliser 1020a, 1020b, 1020c. Furthermore, in the example embodiment of Figure 10a, the first structure is provided with centralizers 1040 to space the first structure within the second structure 1085. Advantageously, such centralisers 1040 may prevent damage to each support apparatus 1000 during installation.

Also shown is a positioning apparatus 1030, which may be used for positioning the support apparatuses 1000 and/or the collar. For example, in one use case, the frames may be coupled to the positioning apparatus by one or more cables, chains or ropes (not shown), such that the support apparatuses 1000 and/or the collar 1095 may be lowered into a desired position relative to the positioning apparatus 1030. Such cables, chains or ropes may couple one or more eye 1005, 1015 on the frame to one or more eyes on the positioning apparatus 1030.

Figure 10b depicts a schematic diagram of a top view of the arrangement of Figure 10a with each support apparatus 1000 in the second configuration. For purposes of clarity, Figure 10c depicts a schematic diagram of a cross-sectional top view of the arrangement of Figure 10a, wherein the positioning apparatus is not depicted in Figure 10c.

In the second configuration the expandable members 1050 are expanded, e.g. inflated, within the annular gap between the first structure 1075 and the second structure 1085. As such, in the second configuration, the expandable members 1050 may provide a stabilizing and/or centralizing and/or packing and/or gripping and/or supporting and/or lifting and/or positioning force to the first and second structures 1075, 1085.

Similar to the embodiments described in Figures 7a to 9b, each support apparatus 1000 comprises a first planar member 1060 and two second planar members 1065a, 1065b. In the example embodiment of Figure 10b, the first planar member 1060 and two second planar members 1065a, 1065b are formed as separate components, e.g. separate metal sheets, with connections provided at hinge points 1070a, 1070b. The first planar member 1060 may be coupled to the second planar members 1065a, 1065b by at least one of: one or more welds; a mechanical hinge; a living hinge; a fold; a perforation; one or more bolts, screws, fasteners, clips or pins. It will be appreciated that in other embodiments, the first planar member 1060 and two second planar members 1065a, 1065b are formed as a monolithic structure, e.g. a metal sheet with folds similar to the embodiment depicted in Figures 7a and 7b.

Due to forces acting upon the first planar member 1060 by expansion of the expandable element 1050, the first planar member 1060 is held between an inner surface of the second structure 1085 and an outer surface of the expandable element 1050. In such a configuration, the first planar member 1060 and the second planar members 1065a, 1065b may be under tension. That is, the first planar member 1060 and the second planar members 1065a, 1065b may be configured to be biased towards the first configuration, e.g. a configuration similar to the first configuration depicted in Figures 7a, 8a and 9a.

As such, upon transifioning the expandable element 1050 back towards an unexpanded configuration, e.g. by deflating the expandable elements 1050, the first planar member 1060 and the second planar members 1065a, 1065b may return to the first configuration. In some embodiments, the first planar member 1060 and the second planar members 1065a, 1065b may undergo a degree of deformation due to expansion of the expandable element 1050, such that upon a subsequent transition to the unexpanded state, the first planar member 1060 and the second planar members 1065a, 1065b fail to return fully to their original first state, e.g. they return to a third state that may be similar to but slightly different from the first state.

Advantageously, a biasing force applied by the first planar member 1060 and the second planar member 1065a, 1065b to the expandable element may assist the expandable element 1050 transitioning to an unexpanded state. That is, the biasing force may for example, assist expulsion of fluid from the expandable element 1050 to deflate the expandable element 1050.

Figure 10d depicts a schematic diagram of a cross-sectional top view of the arrangement of Figure 10a with the support apparatuses 1000 in the first/third configuration. That is, in Figure 10d, the expandable element 1050 has been unexpanded from the expanded second state, and thus the first planar member 1060 and the second planar members 1065a, 1065b have reverted under their own biasing force to the first configuration, or to a third configuration that closely corresponds to the first configuration.

The Applicant discloses in isolation each individual feature described herein and any combination of two or more such features, to the extent that such features or combinations are capable of being carried out based on the specification as a whole in the light of the common general knowledge of a person skilled in the art, irrespective of whether such features or combinations of features solve any problems disclosed herein, and without limitation to the scope of the claims.
