Description

Technical Field

[0001] This application relates to the field of shipbuilding, specifically to a wind power operation and maintenance mother ship. Background Technology

[0002] With my country's advancement towards its "carbon peak and carbon neutrality" goals, offshore wind power is developing rapidly, and wind farms are continuously expanding in scale. While equipment used for wind farm construction, such as large crane vessels and self-elevating installation platforms, is becoming increasingly mature, equipment for operation and maintenance still cannot meet the demands. Currently, small transport boats can be used for personnel transport, but long-distance transport in the open ocean and replacement of large components rely on large dedicated maintenance vessels. To improve efficiency, large dedicated maintenance vessels typically consist of a mother vessel and several smaller vessels. The mother vessel is equipped with a trestle and crane to facilitate connection and positioning with the wind turbine platform within the wind farm, as well as the transport of personnel and spare parts. However, while existing wind power maintenance mother vessels can mitigate some wave effects through trestle bridges, they still cannot achieve complete stability for operations requiring higher installation precision, such as blade replacement.

The lifting components are installed on the deck. Each lifting component is used to drive its corresponding leg to move up and down relative to the hull along the lifting channel.

[0008] The trestle assembly includes an elevator tower, connecting components, and the trestle itself. The elevator tower is vertically mounted on the deck, and the connecting components are mounted on the elevator tower and connected to the trestle.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0043] See Figures 1-2As shown, a wind power operation and maintenance mother ship provided according to an embodiment of this application is schematically displayed, including a hull 1000, a hull lifting device 2000, and a trestle device 3000.

[0044] The hull 1000 includes a deck 1100. The hull lifting device 2000 includes multiple legs 2100 and corresponding multiple lifting components 2200. Each leg 2100 cooperates with a lifting channel that runs vertically through the hull 1000. The lifting components 2200 are mounted on the deck 1100, and each lifting component 2200 is used to drive its corresponding leg 2100 to move up and down relative to the hull 1000 along the lifting channel. The pier device 3000 includes an elevator tower 3100, a connecting component 3200, and a pier 3300. The elevator tower 3100 is mounted vertically on the deck 1100. The connecting component 3200 is mounted on the elevator tower 3100 and connects to the pier 3300. The elevator tower 3100 is used for personnel passage, and the connecting component 3200 is used to drive the pier 3300 to move up and down and to rotate the pier 3300 in the horizontal direction.

[0045] Among them, such as Figure 1 and Figure 2 As shown, the legs 2100 descend along the lifting channel penetrating the hull 1000 and, upon contact with the bottom, provide a reaction force to lift the hull 1000. Multiple legs 2100 are symmetrically distributed on the deck 1100 to evenly bear the load of the hull 1000. The lifting mechanism 2200 can employ a rack and pinion type or a hydraulic pin type mechanism.

[0046] The hull 1000 serves as the foundation platform for the entire wind turbine maintenance mother ship, carrying all equipment, personnel, and maintenance materials. After the mother ship arrives near the wind turbine platform, to ensure greater stability, the lifting mechanism 2200 lowers the legs 2100 to the seabed to position the mother ship. Once the legs 2100 are firmly anchored on the seabed, the lifting mechanism 2200 continues to drive the legs 2100 relative to the hull 1000, raising the hull 1000 above the sea surface to further increase its stability and reduce the impact of waves. After the hull 1000 stabilizes at a fixed height, the trestle device 3000 adjusts the height and horizontal angle of the trestle 3300 via the connecting component 3200 to connect with the wind turbine platform. Maintenance personnel then ascend from the deck via the elevator tower 3100 to the trestle 3300 and reach the wind turbine platform. The height by which the pile leg 2100 raises the hull 1000 and the height by which the trestle 3300 rises in the vertical direction of the elevator tower 3100 can be set according to the height of the wind turbine platform.

[0047] In some embodiments, such as Figure 3 and Figure 4As shown, the connecting component 3200 includes: a lifting mechanism 3210, a rotating mechanism 3220, and a pitching mechanism 3230.

[0048] The lifting mechanism 3210 includes a lifting rail 3211, a lifting base 3212, and a drive assembly. The lifting rail 3211 is arranged vertically on one side of the elevator tower 3100. The end of the lifting base 3212 near the elevator tower 3100 is connected to the lifting rail 3211. The drive assembly is used to drive the lifting base 3212 to move vertically along the lifting rail 3211.

[0049] The slewing mechanism 3220 is mounted on the lifting base 3212 and rotatably connected to the lifting base 3212. The end of the mechanism away from the elevator tower 3100 is connected to the trestle bridge 3300 and is used to drive the trestle bridge 3300 to rotate in the horizontal direction.

[0050] One end of the pitch mechanism 3230 is hinged to the lifting base 3212, and the other end is hinged to the trestle 3300.

[0051] The lifting mechanism 3210 can employ a hydraulic cylinder or a lead screw mechanism as its drive component. This drive component moves the lifting base 3212 vertically to compensate for the height difference between the hull 1000 and the wind turbine platform after the hull is raised. The slewing mechanism 3220 can rotate itself via a slewing bearing and a slewing motor. The pitching mechanism 3230 can employ a hydraulic cylinder or an electric push rod, which, through its extension and retraction, pushes and pulls the trestle 3300 up and down around the horizontal axis connected to the slewing mechanism 3220. Thus, the lifting mechanism 3210 controls the vertical height of the trestle 3300, the slewing mechanism 3220 controls the horizontal angle of the trestle 3300, and the pitching mechanism 3230 controls the vertical pitch angle of the trestle 3300, enabling precise docking of the trestle 3300 with the wind turbine platform.

[0052] In addition, if the wind power operation and maintenance mother ship is in a floating state and the trestle 3300 is connected to the wind turbine platform, the slewing mechanism 3220 and the pitching mechanism 3230 are not completely locked. That is, the rotation angle and pitch angle of the trestle 3300 in the horizontal direction will be slightly adjusted with the sway of the hull 1000 to compensate for the relative movement between the hull 1000 and the wind turbine platform, thereby ensuring that the connection between the trestle 3300 and the wind turbine platform remains stable and improving the safety of transportation.

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the trestle 3300 includes a first trestle section 3310, a second trestle section 3320, and a drive mechanism.

[0054] One end of the first trestle segment 3310 is connected to the connecting component 3200, one end of the second trestle segment 3320 is slidably connected to the first trestle segment 3310, and an abutment device 3330 is provided at the end of the second trestle segment 3320 away from the first trestle segment 3310. The driving mechanism is used to drive the second trestle segment 3320 to move along the length direction of the first trestle segment 3310.

[0055] The trestle 3300 is a telescopic design, with one end hinged to the connecting component 3200 and the other end being a free and telescopic end. A bracing device 3330 is located at the free end, allowing it to rest against the wind turbine platform for easy length adjustment as needed. After the connecting component 3200 is aligned, the second trestle section 3320 of the trestle 3300 extends and is adjusted to the appropriate length, pressing against the wind turbine platform. The drive mechanism can be a hydraulic cylinder or other driving component. One end of the drive mechanism is connected to the first trestle section 3310, and the other end is connected to the second trestle section 3320. The first trestle section 3310 can be equipped with a slide rail and a limiting component that cooperates with the second trestle section 3320. The limiting component limits the sliding distance of the second trestle section 3320, ensuring stable and safe sliding.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the wind power operation and maintenance mother ship also includes a crane 4000, which is mounted on pile legs 2100, with the pile legs 2100 passing through the base of the crane 4000. The crane 4000 is a pile-spinning crane, which can save space on the deck 1100. The crane 4000 is used to complete the lifting operations of large equipment.

[0057] In some embodiments, the elevator tower 3100 includes an elevator tower section and an elevator car. The elevator tower section is disposed on the deck 1100, and the elevator car is disposed on the elevator tower section, serving as a platform for personnel to board and pass through. The elevator car can move up and down inside the elevator tower section, allowing personnel to enter the elevator tower 3100 from the deck 1100 and ascend to the height of the trestle 3300 (i.e., the height of the connecting component 3200). The elevator tower 3100 typically has sufficient height to accommodate different tide levels and the height of the wind turbine platform.

[0058] In some embodiments, the elevator car's entrance and exit face the trestle bridge 3300. When the elevator car rises to the height of the trestle bridge 3300, its entrance and exit face the direction of the trestle bridge 3300, allowing people to directly enter the trestle bridge 3300 from the elevator car.

[0059] In some embodiments, each leg 2100 is provided with a footshoe at its bottom, and there are at least four legs 2100 distributed around the hull. Having at least four legs distributed around the hull ensures even stress distribution during platform raising, lowering, or bottoming, preventing the hull from tilting due to waves, wind loads, or tidal changes. Four-point support also provides better resistance to torsional and unbalanced loads. The footshoe at the bottom of each leg increases the contact area with the seabed, preventing excessive sinking of the legs, and also helps to break the adhesion during leg withdrawal.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, a maintenance sub-boat 5000 is installed on deck 1100, located near the ship's side. The wind power maintenance mother ship can release the maintenance sub-boat 5000 during floating operations according to the actual needs of the wind farm, in order to transport personnel and equipment, thereby improving maintenance efficiency and reducing maintenance costs.

[0061] In some embodiments, such as Figure 1 As shown, a propeller 1200 is installed on the lower part of the hull 1000. Multiple propellers 1200 are respectively located at the bow and stern. Each propeller 1200 may include a main propeller, side thrusters, and an azimuth thruster. The main propeller provides forward propulsion, the side thrusters are responsible for lateral fine-tuning, and the azimuth thrusters can generate forces in multiple directions. The propellers 1200 provide power for the hull 1000 to navigate, overcome water resistance, and assist the hull 1000 in adjusting its direction and position.

[0062] In some embodiments, such as Figure 1 As shown, the wind power operation and maintenance mother ship also includes a dynamic positioning system 6000, which is used to control the thrusters 1200. The dynamic positioning system uses the thrusters 1200 to enable the hull 1000 to resist the interference of waves on positioning, so that the hull 1000 can maintain a preset position in a floating state, which can facilitate the wind power operation and maintenance mother ship to carry out operations in a floating state.

[0063] In summary, the wind power operation and maintenance mother vessel provided in this application can position and lift the hull 1000 using the hull lifting device 2000 to eliminate the impact of waves on the stability of the hull 1000. The connecting component 3200 of the trestle device 3000 drives the trestle 3300 to move vertically and rotate horizontally, enabling the trestle 3300 to precisely dock with the wind turbine platform. When the hull 1000 is floating, the connecting component 3200 and the trestle 3300 can compensate for and eliminate the relative movement between the hull 1000 and the wind turbine platform, reducing the impact of waves on the hull's stability and improving operational safety.

[0064] Based on the various embodiments of this application described above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0065] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of this application. In this case, all details can be replaced with equivalent elements, and materials, shapes, and sizes can also be arbitrary.
