    [0001] [001] Various modalities of a wind turbine platform are described here. In particular, the modalities described here refer to an improved floating wind turbine platform for use in large bodies of water.
    [0002] [002] Wind turbines for converting wind energy into electrical energy are known and provide an alternative energy source for energy companies. On land, large groups of wind turbines, often in numbers of hundreds of wind turbines, can be positioned together in a geographical area. These large groups of wind turbines can generate undesirably high levels of noise and can be seen as aesthetically unpleasant. Optimal airflow may not be available for these land-based wind turbines due to obstacles, such as hills, forests and buildings.
    [0003] [003] Groups of wind turbines may also be located on the high seas, but close to the shore in locations where the depths of the waters allow the wind turbines to be fixedly attached to a foundation under the sea. Along the ocean, the air flow of wind turbines is unlikely to be disturbed by the presence of various obstacles (ie, hills, forests and buildings), resulting in higher average wind speeds and more energy. Foundations that require wind turbines to be attached to the seabed in these locations close to the coast are relatively more expensive and can only be obtained at relatively shallow depths, such as a depth of up to about 25 meters.
    [0004] [004] The U.S. National Renewable Energy Laboratory has determined that winds departing the U.S. Coastline along waters having depths of 30 meters or more have an energy capacity of about 3,200 TWh / year. This equates to about 90 percent of the total US energy use of around 3,500 TWh / year. Most offshore wind resources reside between 37 and 93 kilometers offshore at depths of more than 60 meters. Fixed foundations for wind turbines in such deep waters would probably not be economically feasible. This limitation led to the development of floating platforms for wind turbines. Known floating wind turbine platforms are formed from steel and are based on technology developed by the offshore oil and gas industry. There remains a need in the art, however, for improved platforms for floating wind turbine applications. SUMMARY OF THE INVENTION
    [0005] [005] The present application describes several modalities of a wind turbine platform. In one embodiment, a wind turbine platform is configured to float in a body of water and includes a hull defining a hull cavity in it. The hull is formed from reinforced concrete. A tower is configured to mount a wind turbine and is also connected to the hull. An anchor member is connected to the hull and the seabed.
    [0006] [006] In another embodiment, a wind turbine platform configured to float in a body of water includes a hull defining a hull cavity in it. A tower is configured to mount a wind turbine and is connected to the hull and formed from one of reinforced concrete, FRP composite and steel. An anchor member is connected to the hull and the seabed.
    [0007] [007] In an additional embodiment, a wind turbine platform configured to float in a body of water includes a one-piece tower / hull member. The tower / hull member has a hull portion defining a hull cavity and a tower portion defining a turret cavity. The hull and tower portions are separated by a wall, and the tower portion is configured to mount a wind turbine. An anchor member is connected to the hull and the seabed.
    [0008] [008] In another embodiment, a semi-submersible floating platform includes a plurality of substantially hollow pontoon members formed from concrete. A structural member connects each pontoon to an adjacent pontoon. Each structural member is formed as a substantially hollow tube defining a cavity. Each end of each structural member is embedded in a wall of one of the pontoons so that the concrete that defines the wall of the pontoon extends into the cavity of the embedded structural member.
    [0009] [009] Other advantages of the wind turbine platform will become evident to those skilled in the art from the following detailed description, when reading in view of the attached figures. BRIEF DESCRIPTION OF THE FIGURES

    [0046] [0046] The present invention will now be described with occasional reference to the illustrated embodiments of the invention. This invention can, however, be modalized in different ways and should not be interpreted as limited to the modalities exposed here, nor in any type of preference. On the contrary, these modalities are provided so that this disclosure will be more careful and will transmit the scope of the invention to those skilled in the art.
    [0047] [0047] Unless otherwise defined, all technical and scientific terms used here have the same meaning as commonly understood by those commonly versed in the technique to which this invention belongs. The terminology used in describing the invention here is for describing particular embodiments only and is not intended to limit the invention. As used in the description of the invention and in the appended claims, the singular forms "one", "one" and "o (a)" are intended to include plural forms as well, unless the context clearly indicates otherwise.
    [0048] [0048] Unless otherwise indicated, all numerals expressing amounts of ingredients, properties such as molecular weight, reaction conditions, and so on, as used in the specification and claims, must be understood to be modified in all cases by the term “about”. Consequently, unless otherwise indicated, the numerical properties set out in the specification and claims are approximations that may vary depending on the desired properties sought to be obtained in the embodiments of the present invention. Although the numerical ranges and parameters exposing the broad scope of the invention are approximations, the numerical values exposed in the specific examples are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from errors found in their respective measurements.
    [0049] [0049] The modalities of the invention disclosed below generally provide improvements to various types of floating wind turbine platforms, such as spar buoy platforms, tossed legs type platforms, and semi-submersible type platforms. The invention includes improvements to various types of floating wind turbine platforms, including building components of floating wind turbine platforms with selected materials to reduce the total cost of floating wind turbine platforms.
    [0050] [0050] Referring to the figures, particularly Fig. 1, a first embodiment of a floating composite wind turbine platform 10 is shown anchored to the seabed S. The illustrated floating wind turbine platform 10 is a platform of the type ballast stabilized buoy spar and includes a turret 12 attached to a hull 14 in a connection connection 16. Mooring lines 18 are attached to hull 14 and additionally anchored to the seabed S through anchors 19. A wind turbine 20 is mounted to tower 12.
    [0051] [0051] A spar buoy platform maintains its floating stability by keeping its center of gravity below its buoyancy center. This relationship of the center of gravity being below the center of buoyancy is often achieved by filling a long heavy tube or ballast hull comprising water and dense material, such as rocks.
    [0052] [0052] In the embodiments illustrated here, wind turbine 20 is a horizontal axis wind turbine. Alternatively, the wind turbine may be a vertical axis wind turbine, such as that shown at 20 'in Fig. 1A. The size of the turbine 20 will vary based on the wind conditions at the location where the floating wind turbine platform 10 is anchored, and on the desired energy production. For example, turbine 20 can have a production of about 5 MW. Alternatively, turbine 20 can have a production within the range of from about 1 MW to about 10 MW.
    [0053] [0053] Wind turbine 20 includes a rotating shaft 22. At least one rotating blade 24 is coupled to and extends outward from axis 22. Axis 22 is rotatably coupled to an electrical generator (not shown) . The electrical generator can be coupled via a transformer (not shown) and an underwater power cable 26 to an electrical network (not shown). In the illustrated embodiment, the rotor has three rotating blades 24. In other embodiments, the rotor can have more or less than three rotating blades 24.
    [0054] [0054] In the illustrated embodiment, the tower 12 is formed as a tube and is manufactured from fiber-reinforced polymer composite material (FRP). Non-limiting examples of another suitable composite material include carbon and glass FRP. The tower can also be formed from a composite laminated material as shown at 312 in Fig. 20. The illustrated tower 312 includes a first FRP 314 composite layer, a second FRP 316 composite layer, and a foam core. 318. Alternatively, the tower 12 can be formed from concrete or steel in the same way as hull 14, described in detail below. Additionally, the tower 12 can be formed from steel.
    [0055] [0055] The interior of the tower 12 defines a cavity 13 between a first end 12A (lower end when viewing Fig. 1) and a second end 12B (upper end when viewing Fig. 1). As best shown in Fig. 2, a flange extending radially outward 12F is formed at the first end 12A of tower 12, as best shown in Fig. 1A. The radially extending flange 12F defines a portion of the connection connection 16.
    [0056] [0056] The cavity 13 of the tower 12 can be filled with foam or concrete for added rigidity. In the illustrated embodiment, foam F is shown filling a portion of cavity 13 of tower 12. Alternatively, foam F or concrete (not shown) can fill the entire cavity 13 of tower 12 from the first end 12A to the second end 12B . A non-limiting example of a suitable foam includes polyurethane. Sufficiently rigid material in addition to foam and concrete can also be used to fill or partially fill cavity 13 of tower 12.
    [0057] [0057] Advantageously, the tower 12 formed from the composite material as described above will have reduced mass above a WL water line in relation to a conventional steel tower. Because the FRP composite turret 12 has reduced mass, the mass of hull 14 (for example, self-weighing and ballast; described in detail below) required below the waterline WL to maintain the stability of the floating wind turbine platform 10 can also be reduced. As used here, the waterline is defined as the line where the floating wind turbine platform 10 meets the water surface.
    [0058] [0058] Tower 12 can have any suitable outside diameter and height. In the illustrated embodiment, the outer diameter of the tower 12 narrows from a diameter of about 6 meters at the first end 12A to a diameter of about 4 meters at the second end 12B. Alternatively, the outer diameter of the tower 12 can be any other desired diameter, such as within the range of from about 3 meters to about 12 meters. In the illustrated embodiment, the height of tower 12 is about 90 meters. Alternatively, the height of tower 12 can be within the range of from about 50 meters to about 140 meters.
    [0059] [0059] In the illustrated modality, hull 14 is formed as a tube and is manufactured from reinforced concrete. The interior of hull 14 defines a cavity 15 between a first end 14A (lower end when viewing Fig. 1) and a second end 14B (upper end when viewing Fig. 1). Any desired process can be used to manufacture hull 14, such as an expanded concrete or conventional concrete forms process. Alternatively, other processes, such as those used in the precast concrete industry, can also be used. Hull 14 can be reinforced with any reinforcement member R. Non-limiting examples of suitable reinforcement members R include high strength steel cable and high strength steel reinforcement bars or REBAR. Alternatively, hull 14 can be formed from FRP composite in the same way as tower 12 described above. In addition, hull 14 can be formed from steel.
    [0060] [0060] Hull 14 can have any suitable outside diameter and height. In the illustrated embodiment, hull 14 has a first outer diameter D1 and a second outer diameter D2 that is smaller than the first outer diameter D1. The hull portion 14 having the first outer diameter D1 extends from the first end 14A to a narrowed transition section 14T. The hull portion 14 having the second outer diameter D2 extends from the transition section 14T to a second end 14B. In the illustrated embodiment, the first outer diameter D1 is about 8 meters and the second outer diameter D2 is about 6 meters. Alternatively, the first and second outer diameters D1 and D2 of hull 14 can be any other desired diameters, such as within the range of from about 4 meters to about 12 meters and within the range of from about 4 , 5 meters to about 13 meters, respectively. In addition, hull 14 can have a uniform outer diameter. In the illustrated embodiment, the height of hull 14 is about 120 meters. Alternatively, the height of hull 14 can be within the range of from about 50 meters to about 150 meters.
    [0061] [0061] A flange extending radially outward 14F is formed at the second end 14B of hull 14, as best shown in Fig. 2. The flange extending radially 14F defines a portion of connection connection 16. A first end 14A hull 14 is closed by a plate 14P. The plate 14P can be formed from any suitable substantially rigid material, such as steel. Alternatively, the first end 14A of hull 14 can be closed by a plate 14P. The plate 14P can be formed from any suitable substantially rigid material, such as steel.
    [0062] [0062] In the illustrated mode, connection connection 16 is formed by connecting flange 12F and flange 14F. In the embodiment illustrated in Fig. 2, flanges 12F and 14F are connected by screws 34 and nuts 36. Alternatively, flanges 12F and 14F can be connected by any other desired fasteners, such as rivets, adhesives, or by welding.
    [0063] [0063] It will be understood that the flange 12F of the tower 12 and the flange 14F of the hull 14 can be formed as flanges extending radially inwards so that the fasteners (for example, the screws 34 and nuts 36) are installed inside the tower and hull cavities 13 and 15, respectively.
    [0064] [0064] As shown in Fig. 2, hull cavity 15 can be filled with ballast B to stabilize the floating wind turbine platform 10. In the illustrated embodiment, this ballast B is shown filling a portion of hull cavity 15 14, such as bottom 1/3 of the cavity 15. Alternatively, the ballast B can fill any other desired portion of the cavity 15 of the hull 14 from the first end 14A to the second end 14B. In the illustrated modality, ballast B is shown as rocks. Other non-limiting examples of suitable ballast material include water, steel fragments, copper ore and other dense ores. Another sufficiently dense material can also be used as ballast to fill or partially fill cavity 15 of hull 14.
    [0065] [0065] Hull 14 can be precast in a location far from the location where the floating wind turbine platform 10 will be positioned. During the manufacture of hull 14, reinforcement members R can be pre-tensioned. Alternatively, during the manufacture of hull 14, reinforcement members R can be post-tensioned. Advantageously, the reinforced concrete hull 14 described above is relatively heavy and may require less B ballast than conventional steel hulls.
    [0066] [0066] A first end (upper end when viewing Fig. 1) of each mooring line 18 is attached to hull 14. A second end (lower end when viewing Fig. 1) of each mooring line 18 is attached or anchored to the seabed S by an anchor 19, such as a suction anchor. Alternatively, other types of anchors can be used, such as a drag anchor, gravity anchor or perforated anchor. In the illustrated embodiment, the mooring lines 18 are configured as caternary anchorages. Mooring lines 18 can be formed from any desired material. Non-limiting examples of suitable mooring line material include steel cable or rope, steel chain segments and synthetic rope, such as nylon.
    [0067] [0067] Referring to Fig. 19, a second embodiment of a floating composite wind turbine platform is shown at 10 '. The illustrated floating wind turbine platform 10 'is substantially similar to the floating composite wind turbine platform shown at 10, but tower 12 and hull 14 are formed as a one-piece tower / hull member 11. In this embodiment , a connection link 16 is not required. The one-piece tower / hull member 11 can be formed from FRP composite in the same way as tower 12, described in detail above. Alternatively, the one-piece tower / hull member 11 can be formed from reinforced concrete in the same way as hull 14, described in detail above.
    [0068] [0068] The interior of the tower / hull member 11 defines an elongated cavity 17 within the tower / hull member 11. In the illustrated embodiment, a wall 38 extends transversely within the cavity 17 and divides the cavity 17 into a cavity of tower portion 13 'and hull portion cavity 15'. At least a portion of the tower portion cavity 13 'can be filled with foam or concrete (not shown in Fig. 19) for added stiffness as described above. At least a portion of the hull portion cavity 15 'can be filled with ballast (not shown in Fig. 19) to stabilize the floating wind turbine platform 10' as described above.
    [0069] [0069] With reference to Figs. 3A to 3L, alternative connection connection modalities are shown in 16A to 16H, respectively. As shown in Fig. 3A, a portion of a first alternative embodiment of the connection link is shown at 16A. In the illustrated embodiment, turret 12-1 and hull 14-1 are formed from FRP composite as described above. The connection port 16A includes a turret 12-1 and a hull 14-1. Each of a pair of collar members 12-1C includes a cylindrical collar portion 110 and a flange portion 112. The collar members 12-1C can be formed integrally with the FRP composite tower 12-1 and the hull 14-1, respectively. In the embodiment illustrated in Fig. 3A, the flange portions 112 are connected by screws 34 and nuts 36. Alternatively, the flange portions 112 can be connected by any other desired fasteners, such as rivets, or by welding.

A radially extending flange 12-2F is formed at the first end 12-2A of tower 12-2, and a radially extending flange 14-2F is formed at the second end 14-2F of hull 14-2. The radially extending flange 12F defines a portion of the connection connection 16. In the embodiment illustrated in Fig. 3B, flanges 12-2F and 14-2F are connected by screws 34 and nuts 36. Alternatively, flanges 12-2F and 14-2F can be connected by any other desired fasteners or by welding.
    [0071] [0071] As shown in Fig. 3C, a portion of a third alternative embodiment of the connection link is shown in 16C.

In the illustrated embodiment, turret 12-6 and hull 14-6 are formed from FRP composite as described above. A slit 12-6N is formed at the first end 12-6A of the tower 12-6 and a slit 14-6N is formed at the second end 14-6B of hull 14-6. Slit 12-6N of the first end 12-6A of tower 12-6 is inserted into slot 14-6N of the second end 14-6B of hull 14-6 to define an overlap connection.
    [0075] [0075] As shown in Fig. 3G, a portion of an alternative seventh connection connection mode is shown in 16G. In the illustrated embodiment, the connection connection 16G is substantially identical to the connection connection 16F, except that a layer of adhesive is applied between the slits 12-7N and 14-7N.

Non-limiting examples of suitable FRP composite material include carbon and glass FRP. Alternatively, the tower 62 can be formed from concrete or from steel, as described above.
    [0099] [0099] Because the cable supports 64 reduce the bending stress in tower 62, tower 62 can be of a smaller diameter than tower 12 shown in Fig. 8. For example, tower 62 can have any outside diameter and height appropriate. In the illustrated embodiment, the outer diameter of the tower 62 is about 4 meters. Alternatively, the outer diameter of the tower 62 can be any other desired diameter, such as within the range of from about 3 meters to about 10 meters.

The second end (top end when viewing Fig. 11 ) of each cable post 64 is attached to a middle part 62M of tower 62. Cable posts 64 support and reduce the bending stress in tower 62. Cable posts 64 can be formed from any desired material. Non-limiting examples of suitable mooring line material include steel cable or rope, steel chain segments, synthetic rope such as nylon rope, and composite tendons, such as FRP tendons.
    [0103] [00103] Referring now to Fig. 12, a fourth embodiment of a floating composite wind turbine platform 70 is shown anchored to the seabed S.

    [0107] [00107] The pontoon platform 84 includes a plurality of floating members or pontoons 86 connected by structural members 88. In the illustrated embodiment, the pontoon platform 84 has three pontoons 86. In other embodiments, the pontoon platform 84 may have more or less less than three pontoons 86. The illustrated pontoons 86 have a radially extending flange 87 formed at a first end 86A of each pontoon 86. Alternatively, the pontoons 86 can be formed without the flanges 87.
    [0108] [00108] In the pontoon platform 84 mode as shown in Fig. 13, tower 82 can be attached to a pontoon 86 through a connector connection (not shown). This connector connection can be any of the connection connections described and illustrated in Figs. 2, 3A to 3L, and 4. In a second embodiment of the pontoon platform 84 'as shown in Fig. 16, the pontoons 86 are connected to a central axis 92 by structural members 94. In this embodiment, the tower 82 is attached to the central axis 92 via a connector connection (not shown), but like any of the connection connections described and illustrated in Figs. 2, 3A to 3L, and 4.

Non-limiting examples of suitable mooring line material include steel cable or rope, steel chain segments and synthetic rope, such as nylon rope, and composite tendons, such as FRP tendons.
    [0113] [00113] Referring now to Fig. 14, a sixth embodiment of a floating composite wind turbine platform 100 is shown anchored to the seabed S. The illustrated floating wind turbine platform 100 is substantially similar to the floating turbine platform. floating composite wind 80 illustrated in Fig. 13 and includes a tower 102 attached to the pontoon platform 84, as described above. Each mooring line 90 is attached to a pontoon 86 of the pontoon platform 84 and additionally anchored to the seabed S through anchor 19. Wind turbine 20 is mounted to tower 102. A cable prop 104 is attached to each pontoon 86 of the pontoon platform 84 and additionally attached to a first end 102A of the tower 102.
    [0114] [00114] Because the cable supports 104 reduce the bending stress in tower 102, tower 102 can be of a smaller diameter than tower 82 shown in Fig. 13. For example, tower 102 can have any outside diameter and height appropriate. In the illustrated embodiment, the outer diameter of the tower 102 is about 4 meters. Alternatively, the outer diameter of the tower 102 can be any other desired diameter, such as within the range of from about 3 meters to about 12 meters. In the illustrated embodiment, the height of tower 102 is about 90 meters. Alternatively, the height of tower 102 may be within the range of from about 50 meters to about 140 meters.
    [0115] [00115] Referring now to Fig. 15, the pontoon platform 84 may include a rotating turret 106 mounted to a lower end of the pontoon platform 84. In the embodiment illustrated in Fig. 15, the mooring lines 90 are attached to the turret rotating 106, instead of pontoons 86. In this modality, the floating composite wind turbine platform, like platforms 80 and 100, can rotate in relation to turret 106 and thus self-align in response to the wind direction and ocean currents.
    [0116] [00116] Referring now to Figs. 17, 18A and 18B, a third embodiment of the pontoon platform is illustrated at 140. The pontoon platform 140 includes a plurality of floating members or pontoons 142 connected by structural members 144. In the illustrated embodiment, the pontoon platform 140 has three pontoons 142. In other embodiments, the pontoon platform 140 may have more or less than three pontoons 142. The illustrated pontoons 142 have a radially extending flange 146 formed at a first end 142A of each pontoon 142. Alternatively, the pontoons 142 may be formed without flanges 146.
    [0117] [00117] In the illustrated embodiment, the pontoons 142 are substantially hollow, define a cavity and are formed from reinforced concrete. The structural members 144 illustrated are substantially tubular, define a cavity 145 and are formed from FRP composite.
    [0118] [00118] As best shown in Fig. 18A, in a first embodiment of the pontoon platform 140, the pier 142 includes an external wall 142W. The first and second ends 144A and 144B, respectively, of the structural members 144 are inserted in the outer walls 142W of the pontoons 142. The concrete that forms the outer wall 142W extends into the cavities 145 of each structural member 144 to define a member rigidity 148. When cured, rigidity member 148 provides added rigidity to the pontoon platform 140.
    [0119] [00119] A second modality of the pontoon platform is illustrated at 140 'in Fig. 18B. The pontoon platform 140 'is substantially identical to the pontoon platform 140, but does not include stiffness member 148. The first and second ends 144A and 144B, respectively, of structural members 144 are inserted inwardly and joined to outer walls 142W of the pontoons 142.
    [0120] [00120] The stiffness member 148 can be formed by inserting the first and second ends 144A and 144B, respectively, of the structural members 144 into a pontoon shape (not shown) that defines the shape of the pontoon to be formed. The concrete can be poured into the pontoon shape to define the outer wall 142W of the pontoon 142. This concrete will also be fluid into the cavity 145 of the structural member 144. When the concrete is cured, the concrete of the rigidity member 148 is contiguous to the concrete of the outer wall 142W of the pier 142, thus, the first and second ends 144A and 144B of the structural members 144 are respectively embedded in and joined to the pontoons 142. Additionally, an external surface of each of the first and second ends 144A and 144B, respectively, the structural members 144 can be textured so that each external surface locks and joins the concrete of the external walls 142W of the pontoons 142.
    [0121] [00121] It will be understood that structural members 144 can also be formed from reinforced concrete or from steel as described above.
    [0122] [00122] In the modality of the pontoon platform 140 as shown in Fig. 17, a tower, such as tower 82 (illustrated by a phantom line in Fig. 17), can be attached to one of the pontoons 142 through a connection of connector (not shown). This connector connection can be any of the connection connections described and illustrated in Figs. 2, 3A to 3L, and 4.

In the embodiment illustrated, the pontoon platform 440 has three pontoons 442. In other embodiments, the pontoon platform 440 may have more or less than three pontoons 442. The illustrated pontoons 442 have a radially extending flange 448 formed at a first end 442A of each pontoon 442. Alternatively, pontoons 442 can be formed without flanges 448. In this embodiment, a turret, such as turret 82, is attached to the central pontoon 444 via a connector connection (not shown), but just like any other one of the connection connections described and illustrated in Figs. 2, 3A to 3L, and 4. Alternatively, tower 82 can be attached to any of the three pontoons 442.
    [0124] [00124] Each of the pontoons 442 illustrated is formed from a plurality of rings or sections 450. Sections 450 are connected together in connection connections 452. As described above in relation to hull 14, sections 450 can be manufactured from FRP composite material, reinforced concrete or steel. Sections 450 can be connected by post-tensioning cables 454 running through part or all of sections 450, thus securing sections 450 together and defining the pontoon 442. A sealing member, such as gasket G, can be arranged between sections 450 for sealing connection connections 452. Alternatively, connection connections 452 can be any of the connection connections described and illustrated in Figs. 2, 3A to 3L, and 4.
    [0125] [00125] Attachment rings 456 are mounted circumferentially to an outer surface of pontoons 442 and provide a mounting structure for attaching structural members 446 to pontoons 442. Attachment rings 456 can be formed from steel, composite material FRP or reinforced concrete. Alternatively, the attachment rings 456 can be mounted on the connection port 452 between two adjacent sections 450.
    [0126] [00126] Since the sections 450 are arranged to form the pontoon 442, a closing member 458 can be attached to the second end 442B of the pontoon 442.
    [0127] [00127] The principle and mode of operation of the wind turbine platform were described in their preferred modalities.
