[0017] Optionally, in the above-mentioned floating wind turbine platform, the ballast component includes concrete or steel components.

[0018] Optionally, in the above-mentioned floating wind turbine platform, the top of the central column is provided with a mounting flange for connecting to the wind turbine.

[0019] A method for installing a floating wind turbine platform, applicable to any of the floating wind turbine platforms described above, comprising:

[0020] The assembly wind turbine platform is formed by assembling the various modules of the floating wind turbine platform. The modules include the central column, the side columns, the bypass float, the transition piece, the ballast piece, and the connecting mechanism, and the connecting mechanism is in a shortened state.

[0021] The transport wind turbine platform is used to transport the floating wind turbine platform to the target location, and the connecting mechanism extends to lower the ballast member to the target depth;

Detailed Implementation

[0035] The core of this application is to provide a floating wind turbine platform that improves the assembly efficiency of the floating wind turbine platform while taking into account its stability and ease of transportation.

[0036] Another core aspect of this application is to provide a floating wind turbine platform installation method applicable to the aforementioned floating wind turbine platform.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The design and construction of floating wind turbine platforms largely rely on large fixed platforms or semi-submersible platforms. While these platforms offer good stability and resistance to wind and waves, traditional floating platform designs often require complex on-site assembly and commissioning, resulting in long production cycles and significant challenges during transportation and installation. Furthermore, as offshore wind farms continue to expand, existing design and construction methods are struggling to meet the demands for rapid construction and efficient operation and maintenance.

[0039] Therefore, such as Figure 1 As shown in the illustration, this application discloses a floating wind turbine platform 100, including a floating platform 10, a ballast component 20, a connecting mechanism 30, and a mooring system. The connecting mechanism 30 drives the ballast component 20 to move towards or away from the floating platform 10, allowing the ballast component 20 to switch between a retracted position for transportation and an extended position for in-situ operation. This balances the stability of the floating wind turbine platform 100 with ease of transportation. Furthermore, the floating platform 10 of the floating wind turbine platform 100 adopts a modular design, enabling factory-based and parallel production, shortening the construction cycle, and allowing for long-distance transportation using ordinary cargo ships, further reducing costs and improving the assembly efficiency of the floating wind turbine platform 100.

[0040] The following will combine Figures 1 to 5 The floating wind turbine platform 100 disclosed in the embodiments of this application will be explained and described in detail.

[0041] like Figure 1 As shown, the floating platform 10 can adopt a semi-submersible platform structure to provide sufficient buoyancy and initial stability for the wind turbine. The floating platform 10 may include a central column 11 that can be connected to the wind turbine and multiple side column assemblies 12, and there may be three, four or more side column assemblies 12, which may be radially distributed around the central column 11. The central column 11 may adopt a hollow tubular structure, and a mounting flange is provided at the top of the central column 11 so that it can be rigidly connected to the tower of the wind turbine, thereby transferring the weight of the wind turbine and the environmental loads it experiences to the entire floating platform.

[0042] like Figure 1 As shown, the side column assembly 12 may include a side column 121, a bypass float 122, and a transition member 123. The side column 121 may be located at the outermost end of the side column assembly 12, and may be a hollow tubular structure to provide waterline area for the floating platform 10, ensuring the heel and pitch stability of the floating platform 10 under various draft conditions. The bypass float 122 may be a horizontally arranged tubular structure, with one end rigidly connected to the central column 11 and the other end connected to the transition member 123. The transition member 123 is also rigidly connected to the lower part of the side column 121. Through these connections, the central column 11, side column 121, bypass float 122, and transition member 123 together constitute a complete floating platform 10 with high rigidity and strength.

[0043] In some embodiments, such as Figure 2 and Figure 3As shown, to achieve modular manufacturing and convenient transportation, the main components of the floating platform 10, including but not limited to the central column 11, side columns 121, bypass floats 122, and transition pieces 123, can all adopt tubular structures. This facilitates standardized production in a factory environment using steel plate rolling and welding processes. Simultaneously, the diameter of the central column 11 is larger than the diameter of each bypass float 122 to ensure that the connections between the bypass floats 122 and the central column 11 do not interfere with each other. A complete side column 121 can be formed by connecting several side column segment modules using bolts or other fasteners via connecting flanges 13; a complete bypass float 122 can also be formed by splicing several bypass float segment modules using bolts or other fasteners via connecting flanges 13. The bypass floats 122 and the side columns 121 are connected via transition pieces 123, which can also be connected using connecting flanges 13. By employing a rigid connection method using connecting flange 13, not only is the strength and watertightness of the connection ensured, but on-site installation and assembly work is also simplified, thereby shortening the construction cycle. Of course, permanent rigid connections can also be made between the modules through on-site welding.

[0044] In some embodiments, to achieve precise attitude adjustment of the floating platform 10, such as compensating for uneven loads during installation or operation, ballast compartments can be provided inside at least one of the side pillars 121 and the bypass floats 122. Ballast compartments can be provided inside either the side pillars 121 or the bypass floats 122, or simultaneously in both. Specifically, the internal spaces of the side pillars 121 and the bypass floats 122 can be divided into several independent ballast compartments. By pumping seawater into or out of each ballast compartment, the weight, center of gravity, and tilt attitude of the floating platform 10 can be actively changed, thereby achieving precise leveling of the floating platform 10.

[0045] In some embodiments, the central column 11 may also be provided with cable channels that can communicate with each ballast compartment. This allows the fans on the central column 11 to be connected to the water pumps and other electrical equipment in each ballast compartment via cables, enabling the fans to generate electricity to power the equipment in each ballast compartment. This eliminates the need for an external power supply, simplifies the structure of the floating platform 10, and saves costs. It should be noted that each ballast compartment may have an independent equipment compartment for housing water pumps and other electrical equipment, and the cable channels may be sealed to the equipment compartments to prevent water from entering the cable channels and affecting the operation of the electrical equipment.

[0046] In some embodiments, to stably anchor the floating platform 10 in a designated sea area, the mooring cables of the mooring system can be connected to the floating platform 10 to prevent the floating platform 10 from drifting or other movements. Specifically, the mooring system can be connected to the mooring point of the transition member 123. Meanwhile, because the load transmitted by the mooring system is enormous and complex, the mooring point area on the transition member 123 can be structurally reinforced, for example, by increasing the local plate thickness or adding internal reinforcing ribs, to ensure that the mooring point area has sufficient strength and fatigue resistance, thereby safely transferring the environmental load borne by the mooring system to the entire floating wind turbine platform 100.

[0047] like Figures 1 to 4 As shown, the ballast component 20 can be located directly below the floating platform 10 and connected to the floating platform 10 via the connecting mechanism 30 to ensure the stability of the floating platform 10. The ballast component 20 can be made of concrete, specifically high-performance concrete cast in a dock, to provide significant counterweight to the floating platform 10, thereby significantly lowering the overall center of gravity of the entire floating wind turbine platform 100. Alternatively, the ballast component 20 can be made of steel to provide significant counterweight to the floating platform 10. It should be noted that the shape of the ballast component 20 can be, but is not limited to, circular, triangular, or quadrilateral shapes.

[0048] like Figures 1 to 4 As shown, the connecting mechanism 30 is connected between the floating platform 10 and the ballast member 20 with variable length, thereby driving the ballast member 20 to move toward or away from the floating platform 10, so that the ballast member 20 can switch between a retracted position for transportation and an extended position for in-situ operation, thereby meeting the different needs of the floating wind turbine platform 100 in both transportation and operation states.

[0049] When the floating wind turbine platform 100 needs to be transported, such as Figure 4 As shown, the connecting mechanism 30 is shortened to its minimum length, and the lower ballast member 20 is lifted upwards, so that it is close to or adjacent to the bottom of the floating platform 10. At this time, the overall center of gravity of the floating wind turbine platform 100 is higher, but the total draft is reduced, so that the floating wind turbine platform 100 can enter and exit ports and docks with limited water depth. Moreover, when carrying out wet towing transportation at sea, the hydrodynamic resistance is smaller, which helps to reduce the power requirements of tugboats and transportation costs.

[0050] Once the floating wind turbine platform 100 is towed to the designated working area, the connecting mechanism 30 can extend, and the lower ballast member 20 can be lowered to a preset working depth. At this point, the floating wind turbine platform 100 can enter its in-situ working state. Figure 1As shown. In this operating state, the lower ballast component 20 is located at a deeper underwater position, lowering the overall center of gravity of the floating wind turbine platform 100 to a position far below its center of buoyancy. This helps enhance the floating wind turbine platform 100's ability to resist the overturning moment of wind and waves, giving it good stability in pitching and rolling motions. Simultaneously, the deep-submerged ballast component 20 also significantly increases the added mass and hydrodynamic damping of the floating wind turbine platform 100 in heave motion, effectively suppressing the vertical motion amplitude of the floating wind turbine platform 100 in waves, thus ensuring the safe and efficient power generation of the wind turbine in high sea states.

[0051] In some embodiments, such as Figure 2 As shown, the connecting mechanism 30 may include a telescopic drive member 31, one end of which can be connected to the ballast member 20, and the other end of which can be connected to the central column 11. Specifically, the telescopic drive member 31 may be a telescopic hydraulic rod, one end of which can be connected to the bottom of the central column 11, and the other end of which can be connected to the top center of the ballast member 20. The telescopic hydraulic rod may have a multi-stage sleeve structure inside, and its internal piston is driven by a hydraulic power unit to move, thereby realizing the extension and retraction of the entire telescopic hydraulic rod in length. This causes the ballast member 20 to move towards or away from the floating platform 10, so that the ballast member 20 can switch between a retracted position for transportation and an extended position for in-situ operation, thereby meeting the different needs of the floating wind turbine platform 100 in both transportation and operation states.

[0052] In some embodiments, such as Figure 3 As shown, the connecting mechanism 30 may also include a traction member 32 and a take-up and put-down device capable of taking up and putting down the traction member 32. One end of the traction member 32 may be connected to the ballast member 20, and the other end of the traction member 32 may be connected to the central column 11. Specifically, the traction member 32 may consist of three, four, or more high-performance steel cables, and the upper end of the high-performance steel cables may be connected to the take-up and put-down device installed inside or at the bottom of the central column 11. The lower end of the high-performance steel cables may be connected to the upper surface of the ballast member 20 through connectors such as shackles. The take-up and put-down device may consist of one or more high-power synchronous winch systems, and the winch system may include a drive motor, a reducer, a drum, and a braking system. The integrated central control system can control the synchronous rotation of each winch system, thereby achieving synchronous take-up and put-down of all high-performance steel cables to drive the ballast member 20 to move toward or away from the floating platform 10. This allows the ballast member 20 to switch between a retracted position for transportation and an extended position for in-situ operation, thus meeting the different needs of the floating wind turbine platform 100 in both transportation and operation states.

[0053] The floating wind turbine platform 100 disclosed in this application embodiment can be connected to a wind turbine via a central column 11 of the floating platform 10. Multiple side column assemblies 12 can be arranged around the central column 11, and one end of a bypass float 122 is connected to the side column 121 via a transition piece 123, while the other end of the bypass float 122 is connected to the central column 11, ensuring that the wind turbine can float on the water surface via the floating platform 10. Simultaneously, a ballast member 20 is connected to the floating platform 10 via a connecting mechanism 30 to ensure the stability of the floating platform 10. Furthermore, a mooring system can be connected to the transition piece 123 to prevent the floating platform 10 from drifting, thus ensuring the stable operation of the wind turbine.

[0054] The floating wind turbine platform 100 disclosed in this application embodiment allows the ballast member 20 to move towards or away from the floating platform 10 via a connecting mechanism 30. This enables the ballast member 20 to switch between a retracted position for transportation and an extended position for in-situ operation, thus balancing the stability of the floating wind turbine platform 100 with ease of transportation. Furthermore, the floating platform 10 of the floating wind turbine platform 100 adopts a modular design, enabling factory-based and parallel production, shortening the construction cycle, and allowing for long-distance transportation using ordinary cargo ships, further reducing costs and improving the assembly efficiency of the floating wind turbine platform 100.

[0055] This application also discloses a method for installing a floating wind turbine platform, applicable to the floating wind turbine platform 100 disclosed in the above embodiments. Therefore, it possesses all the technical effects of the aforementioned floating wind turbine platform 100, which will not be elaborated upon here. The method for installing the floating wind turbine platform may include the following steps:

[0056] Step A: Assemble the wind turbine platform;

[0057] The various modules of the floating wind turbine platform 100 are assembled. The modules include a central column 11, side columns 121, bypass floats 122, transition pieces 123, ballast pieces 20, and connecting mechanisms 30, with the connecting mechanisms 30 in a shortened state. Specifically, the ballast pieces 20 are first fabricated in the dock by casting. After the ballast pieces 20 are formed, the connecting mechanisms 30 are rigidly connected to the ballast pieces 20, and the connecting mechanisms 30 are shortened to their minimum length. Then, the central column 11 is connected to the connecting mechanisms 30 by hoisting. Subsequently, the bypass floats 122, transition pieces 123, side columns 121, and other modules are hoisted and assembled in sequence. It should be noted that if the floating wind turbine platform 100 needs to be transported over long distances, a transport module for the wind turbine platform can be included before the final assembly step. This means that the various modules of the manufactured floating wind turbine platform 100 can be transported to the target assembly location, such as a port in the target sea area, using a transport vessel 200. Once at the target assembly location, final assembly can be performed according to the assembly sequence described in the above embodiment. For example... Figure 5 As shown, since the floating wind turbine platform 100 is transported in modular form, there is no need to use a dedicated wind turbine vessel or an ultra-large semi-submersible barge. Only an ordinary transport vessel 200 needs to be selected, which can significantly save on transportation costs.

[0058] Step B: Transport the wind turbine platform;

[0059] The floating wind turbine platform 100 is transported to the target location, and the connecting mechanism 30 extends to lower the ballast member 20 to the target depth. Specifically, it can be towed to the target location by wet towing, that is, a tugboat is used to tow the floating wind turbine platform 100, which is in shallow draft, from the dock to the designated deep-sea target location. Upon arrival at the target location, the connecting mechanism 30 extends to lower the ballast member 20 to the working depth, thus transforming the floating wind turbine platform 100 into a highly stable working state.

[0060] Step C, Install the mooring system;

[0061] The mooring system is connected to the transition piece 123. Specifically, multiple mooring cables pre-laid on the seabed are connected to the mooring points on the transition piece 123 of the floating platform 10, and the final positioning and fixation of the floating wind turbine platform 100 is completed by tensioning the mooring cables, thereby completing the installation of the entire floating wind turbine platform 100.
