Description

Technical Field

[0001] This invention relates to a method for transporting and installing floating wind turbines, and more particularly to an integrated method for transporting and installing large floating wind turbines in deep-sea areas. Background Technology

[0002] Offshore wind power, with its clean, large-scale, and cost-controllable characteristics, is gradually becoming an important direction for the development of new energy. As water depth continues to increase, the construction, installation, and subsequent maintenance of stationary wind turbines increase dramatically. Correspondingly, floating wind turbines are more economical and have greater potential in the development and utilization of new energy. Tension leg floating wind turbines can balance environmental loads through inertial forces, eliminating the need for structural internal forces to balance them, thus giving the structure good motion performance.

[0003] Generally, the transportation methods for tension leg wind turbine platforms are mainly divided into wet towing and dry towing. Wet towing requires the addition of temporary pontoons to the wind turbine to ensure transportation stability, and multiple tugboats are needed to maintain the stability of the wind turbine. Dry towing uses barges to transport the wind turbine to the installation area, and then a crane lifts it into the water. However, with the continuous increase in the installed capacity and size of floating wind turbines, the traditional method of adding temporary pontoons to the wind turbine to improve transportation stability is no longer applicable. While the dry towing method can transport large wind turbines to the installation area, it cannot install the wind turbine in the water.

[0004] Therefore, to address the shortcomings of existing methods, the transportation of large wind turbines can be changed by combining the transportation and installation of wind turbines. Semi-submersible barges can be used for semi-wet towing transportation and installation of large wind turbines, which solves the problem that traditional methods cannot be adapted to the installation of large wind turbines and meets the needs of the installation of large floating wind turbines in deep-sea areas. Summary of the Invention

[0005] The main objective of this invention is to provide an integrated transportation and installation method for large-scale floating wind turbines in deep-sea areas, in order to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, an integrated transportation and installation method for a large floating wind turbine in deep-sea areas is provided, comprising a floating foundation, wherein a large floating wind turbine is inserted and installed on the floating foundation, the floating foundation comprising a plurality of interconnected crossbeams forming a triangular closed loop, a fixing plate being fixedly connected at the center of the crossbeams, a central pontoon being fixedly disposed at the center of the fixing plate, the bottom of the large floating wind turbine being inserted and disposed within the central pontoon, and a floating airbag being fixedly disposed at the bottom of the floating foundation as a buoyancy aid structure, the floating airbag being used to provide additional buoyancy to the floating foundation; It also includes a semi-submersible barge and several tugboats. When it is necessary to transport a large floating wind turbine to a designated location at sea, the semi-submersible barge is ballasted to the loading depth, and the tugboats drag the floating foundation to move and insert the floating foundation onto the semi-submersible barge.

[0007] Furthermore, the outer wall of the central pontoon is fixedly connected with several diagonal rods in a circular array. One end of each diagonal rod is fixedly connected to the outer wall of the central pontoon, and the other end is fixedly connected to the upper end of the crossbeam connection.

[0008] Furthermore, the fixed plate has several sliding grooves arranged in a circular array, and a support component is slidably arranged in each of the sliding grooves. The support component includes an inclined support rod, one end of which is fixedly connected to a support plate. One end of the support plate is arc-shaped, and the other end of the support rod is slidably installed in the sliding groove. The support component is used to support a large floating wind turbine.

[0009] Furthermore, a column is fixedly installed inside the central pontoon. The column includes symmetrically arranged connecting rods, and one end of the two connecting rods is hinged together. A crossbar is fixedly connected to the connecting end of the two connecting rods. A slot is opened on the central pontoon, and the crossbar is slidably installed in the slot.

[0010] Furthermore, the floating foundation is used to provide buoyancy for the large floating wind turbine so that it floats on the water surface, and the buoyancy provided by the floating foundation should make its bottom float on the water surface at a height of 1.5 meters.

[0011] Furthermore, the bottom of the fixing plate is provided with an installation groove, the floating airbag is fixedly installed in the installation groove, and the lower end of the floating airbag is fixedly connected with several connecting ropes in a circular array, one end of the connecting ropes being fixedly connected to the lower surface of the fixing plate.

[0012] Furthermore, a number of clamps are fixedly arranged in a circular array at one end of the semi-submersible barge. The lower end of the clamps has a rectangular cross-section and the upper end has a rhomboid cross-section. A groove is opened on the inner side of the lower end of the clamps. A sliding plate is slidably installed in the groove. A number of elastic protrusions are fixedly connected to one side of the sliding plate. A number of springs are fixedly connected to the other end of the sliding plate, and one end of the spring is fixedly connected to the inner wall of the groove.

[0013] Furthermore, the bottom of the fixing plate is fixedly connected with several arc-shaped plates in a circular array, and the outer wall of the arc-shaped plates is provided with several slots, and the elastic protrusion is snapped into the slots.

[0014] Furthermore, each of the crossbeam connections has a side buoy fixedly connected to its lower end, and two chain stoppers are symmetrically fixedly connected to the bottom of each side buoy.

[0015] Furthermore, several anchor piles are fixedly installed at designated locations on the seabed, and each anchor pile is fixedly connected to a mooring leg anchor chain, which is then fixedly connected to the anchor pile via a chain stopper.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This integrated transportation and installation method for large-scale floating wind turbines in deep-sea areas enables integrated loading, transportation, and offshore installation of these turbines. It solves the problems of insufficient buoyancy reserves during towing, inadequate stability of the center of gravity during conventional dry towing transportation, and excessively high risks associated with semi-submersible operations at deep-water installation sites. This significantly improves the installation efficiency and reduces installation risks. The reverse process allows the turbines to be transported back to the dock for major component replacement, addressing the previous limitation of large-scale component replacement in deep-sea floating wind turbines. Furthermore, this method reduces construction steps, simplifies overall operation, facilitates construction, and lowers construction costs and safety risks. Attached Figure Description

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] This embodiment provides an integrated transportation and installation method for a large floating wind turbine in deep-sea areas, including a floating foundation 4. A large floating wind turbine 2 is inserted and installed on the floating foundation 4. The floating foundation 4 includes several interconnected crossbeams 12 forming a triangular closed loop. A fixing plate 13 is fixedly connected to the center of the crossbeams 12. A central pontoon 10 is fixedly installed at the center of the fixing plate 13. The bottom of the large floating wind turbine 2 is inserted and installed in the central pontoon 10. A floating airbag 15 is fixedly installed at the bottom of the floating foundation 4 as a buoyancy aid structure. The floating airbag 15 is used to provide additional buoyancy to the floating foundation 4. It also includes a semi-submersible barge 1 and several tugboats 3. When it is necessary to transport a large floating wind turbine 2 to a set position at sea, the semi-submersible barge 1 is ballasted to the loading depth, and the tugboats 3 drag the floating foundation 4 to move and insert the floating foundation 4 onto the semi-submersible barge 1.

[0021] like Figure 5 As shown, the outer wall of the central pontoon 10 is fixedly connected with several diagonal rods 19 in a ring array. One end of each diagonal rod 19 is fixedly connected to the outer wall of the central pontoon 10, and the other end is fixedly connected to the upper end of the connection point of the crossbeam 12. By setting the diagonal rods 19, the stability of the central pontoon 10 is enhanced, providing a solid guarantee for the installation of the large floating fan 2. The large floating fan 2 is rotatably equipped with fan blades 5.

[0022] like Figure 5 and Figure 6As shown, a plurality of sliding grooves 131 are arranged in a circular array on the fixed plate 13. Supporting components 18 are slidably disposed within each of the sliding grooves 131. Each supporting component 18 includes an inclined supporting rod 181. One end of the supporting rod 181 is fixedly connected to a supporting plate 182, one end of which is arc-shaped to adapt to the shape of the outer wall of the fan. The other end of the supporting rod 181 is slidably installed within the sliding groove 131. The supporting components 18 are used to support the large floating fan 2. When the large floating fan 2 is inserted and installed on the central float 10, the sliding supporting rod 181 causes the arc-shaped surface of the supporting plate 182 to tightly conform to the large floating fan. The outer wall of the floating fan 2 provides stable and uniform support, and a screw is threaded through the lower end of the support rod 181, with one end of the screw threaded into the inner wall of the slide groove 131. Tightening the screw fixes the position of the support rod 181. Therefore, the support component 18 can effectively avoid the risk of tipping over due to the short insertion depth of the large floating fan 2. When the fan is subjected to external forces such as wind and waves, the support component 18 can provide additional support, enhance the stability of the fan, and ensure its normal operation. At the same time, the adjustability of the support component 18 also allows it to adapt to large floating fans 2 of different sizes and shapes, improving its versatility and flexibility.

[0023] like Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, a column 11 is fixedly installed inside the central float 10. The column 11 includes symmetrically arranged connecting rods 111, and one end of the two connecting rods 111 is hinged together. A crossbar 112 is fixedly connected to the connecting end of the two connecting rods 111. A slot 101 is opened on the central float 10. The crossbar 112 is slidably installed in the slot 101, and the lower surface of the large floating fan 2 is in contact with the upper connecting rod 111. When the large floating fan 2 needs to be removed from the central float 10, the crossbar 112 can be pressed inward. The crossbar 112 will drive the two connecting rods 111 to rotate around the hinge point. During the rotation, the non-connecting ends of the two connecting rods 111 gradually move away from each other, forming a scissor-like opening and closing action, thereby lifting the large floating fan 2 upward. During this process, the crossbar 112 slides upward in the slot 101.

[0024] like Figure 5 and Figure 7 As shown, the floating foundation 4 is used to provide buoyancy for the large floating wind turbine 2 so that it floats on the water surface. The buoyancy provided by the floating foundation 4 should make its bottom float on the water surface, and the bottom height above the water surface is 1.5 meters. The buoyancy-aiding structure set at the bottom of the floating foundation 4 can increase the buoyancy to meet the requirements.

[0025] like Figure 5 , Figure 7 and Figure 8 As shown, the bottom of the fixing plate 13 has an installation groove, and the floating airbag 15 is fixedly installed in the installation groove. Several connecting ropes 16 are fixedly connected to the lower end of the floating airbag 15 in a circular array. One end of the connecting rope 16 is fixedly connected to the lower surface of the fixing plate 13. By injecting an appropriate amount of gas into the floating airbag 15, its volume is increased, thereby providing additional buoyancy support. However, as the amount of gas in the floating airbag 15 increases, its volume will also increase accordingly. In this case, the part of the floating airbag 15 placed in the water may shift due to the impact of water flow, wind and waves, etc., and thus cause damage. In order to effectively solve this problem, the connecting ropes 16 are set to limit and fix the floating airbag 15, restricting the displacement range of the floating airbag 15, so that it can play its role in a relatively stable position, avoiding the risk of damage caused by displacement. When the floating airbag 15 is not in use, it is stored in the installation groove in a deflated state.

[0026] like Figure 10 , Figure 11 and Figure 12 As shown, a number of clamping plates 14 are fixedly arranged in a circular array at one end of the semi-submersible barge 1. The lower end of the clamping plate 14 has a rectangular cross-section and the upper end has a rhomboid cross-section. A groove 141 is opened on the inner side of the lower end of the clamping plate 14. A sliding plate 142 is slidably installed in the groove 141. A number of elastic protrusions 144 are fixedly connected to one side of the sliding plate 142. A number of springs 143 are fixedly connected to the other end of the sliding plate 142, and one end of the spring 143 is fixedly connected to the inner wall of the groove 141.

[0027] like Figure 7 and Figure 12 As shown, the bottom of the fixed plate 13 is fixedly connected with several arc-shaped plates 17 in a ring array. The outer wall of the arc-shaped plates 17 is provided with several slots, and the elastic protrusions 144 are snapped into the slots.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 12As shown, when it is necessary to transport the large floating wind turbine 2 to a designated location at sea, the stern of the semi-submersible barge 1 is aligned with the large floating wind turbine 2, ballasted to the designed loading depth, and tugboats 3 are used to drag the triangular edge of the floating foundation 4 until the bottom of the large floating wind turbine 2 is at the designated position above the deck of the semi-submersible barge 1. The semi-submersible barge 1 begins unloading, the deck surface rises, and the curved plate 17 is gradually inserted into the middle area of ​​each clamping plate 14. The diamond-shaped cross-section at the upper end of the clamping plate 14 plays a good guiding role, allowing the curved plate 17 to be accurately aligned with the center area for insertion. The spring 143 connected to one end of the sliding plate 142 allows the sliding plate 142 to tightly clamp the curved plate 17. As the arc-shaped plate 17 is gradually inserted, the elastic protrusion 144 contracts under the pressure from the side wall of the arc-shaped plate 17 until it is fully aligned with the slot and returns to its original position, thereby firmly installing the floating foundation 4 on the semi-submersible barge 1. During this process, the gas in the floating airbag 15 needs to be gradually extracted to reduce the buoyancy of the floating foundation 4, so that it can be installed more stably on the semi-submersible barge 1. When it is necessary to unload the floating foundation 4 and the large floating wind turbine 2 on it, the semi-submersible barge 1 is ballasted downwards. During this process, the floating airbag 15 needs to be gradually inflated. Under the action of buoyancy, the floating foundation 4 gradually detaches from the central area of ​​the clamping plate 14, and the elastic protrusion 144 detaches from the slot.

[0029] like Figure 1 As shown, when loading the floating foundation 4, the dimensions of the floating foundation 4 in both the forward and lateral directions are larger than the deck width of the semi-submersible barge 1, allowing it to be towed onto the barge from different directions. When the large floating wind turbine 2 is towed onto the barge in the forward direction, its bottom gradually enters the stern of the semi-submersible barge 1 until the two side buoys 8 pass through the stern, and the last side buoy contacts the stern, placing the large floating wind turbine 2 at the stern of the barge. The wind turbine is positioned at the stern of the semi-submersible barge 1 during the forward loading process, and the barge should have sufficient load-adjusting capacity. When the large floating wind turbine 2 is towed onto the barge in the lateral direction, the three side buoys 8 of the wind turbine floating foundation 4 pass through the stern, allowing it to be loaded and positioned at any location on the semi-submersible barge 1. At least three tugboats 3 are required to tow the wind turbine, with two tugboats 3 facing the barge and one tugboat 3 facing away from the barge.

[0030] like Figure 3 As shown, the lower end of each crossbeam 12 is fixedly connected to a side buoy 8. Two chain stoppers 9 are symmetrically fixedly connected to the bottom of each side buoy 8. After the large floating wind turbine 2 is loaded onto the ship, the central buoy 10 is on the barge, and the three side buoys 8 extend out of the ship. The chain stoppers 9 are below the deck level.

[0031] like Figure 2 and Figure 3As shown, several anchor piles 7 are fixedly installed at designated locations on the seabed. Each anchor pile 7 is fixedly connected with a mooring leg anchor chain 6, and the mooring leg anchor chain 6 passes through a chain stopper 9 and is fixedly connected to the anchor pile 7. The mooring leg anchor chain 6 can be pre-connected to the anchor piles 7 driven into the seabed, and installed by passing through the chain stopper 9 from bottom to top after the wind turbine is transported and placed in place. Alternatively, the mooring leg anchor chain 6 can be passed through the chain stopper 9 from top to bottom after the wind turbine is placed in place, and then connected to the seabed anchor pile 7 to complete the installation.

[0032] In practical use, anchor piles 7 are driven into designated locations on the seabed in advance, and the large floating wind turbine 2 is inserted and installed on the central buoy 10 in the harbor basin. The sliding support rod 181 is used to move the support plate 182. The large floating wind turbine 2 is tightly fitted to the outer wall, and then the screws penetrating the lower end of the support rod 181 are tightened to fix the position of the support rod 181, providing stable and uniform support for the large floating wind turbine 2. An appropriate amount of gas is injected into the floating airbag 15 to increase its volume and provide additional buoyancy support. The stern of the semi-submersible barge 1 is aligned with the large floating wind turbine 2 and ballasted to the designed loading depth. The triangular edge of the floating foundation 4 is dragged by tugboat 3. The forward or side-towing loading method is selected according to the actual situation. When the bottom of the large floating wind turbine 2 is in the designated position above the deck of the semi-submersible barge 1, the semi-submersible barge 1 begins to unload. The deck surface rises, and the arc plate 17 is gradually inserted into the middle area of ​​each clamp plate 14. The diamond-shaped section at the upper end of the clamp plate 14 plays a guiding role, so that the arc plate 17 can be accurately aligned with the center area for insertion. The spring 143 connected to one end of the sliding plate 142 makes the sliding plate 142... 42 can tightly clamp the arc-shaped plate 17. As the arc-shaped plate 17 is gradually inserted, the elastic protrusion 144 is compressed by the pressure from the side wall of the arc-shaped plate 17 until it is completely aligned with the slot and returns to its original position, thereby firmly installing the floating foundation 4 on the semi-submersible barge 1. During this process, the gas in the floating airbag 15 is gradually extracted to reduce the buoyancy of the floating foundation 4, so that it can be installed more stably on the semi-submersible barge 1. The semi-submersible barge 1, carrying the large floating wind turbine 2 and the floating foundation 4, sails to the designated position at sea. When the semi-submersible barge 1 reaches the designated position at sea, it begins to be ballasted downwards. At the same time, the floating airbag 15 is gradually inflated. Under the action of buoyancy, the floating foundation 4 gradually detaches from the central area of ​​the clamping plate 14, and the elastic protrusion 144 detaches from the slot, allowing the semi-submersible barge 1 to sail away. Then, the mooring leg anchor chain 6 is installed by passing it through the chain stopper 9 from bottom to top, or the mooring leg anchor chain 6 is installed after the wind turbine is in place. The chain stop 9 is passed from top to bottom and then connected to the seabed anchor pile 7 to complete the mooring installation of the large floating wind turbine 2.
