[0002] With the continuous growth of global demand for clean energy, the wind power industry has developed rapidly. High-power wind turbine equipment, due to its advantages such as large power generation and high efficiency, has gradually become the mainstream choice for wind farm construction. However, high-power wind turbine equipment is characterized by its large size, heavy weight, and complex structure; its blades can reach lengths of over 100 meters, and its nacelle can weigh hundreds of tons. Currently, multi-purpose transport vessels can only transport individual wind turbine units, requiring the entire wind turbine equipment to be transported to port before installation can be arranged, significantly increasing the installation cycle.

[0003] Currently, traditional multi-purpose transport vessels face numerous problems when transporting high-power wind turbine equipment: (1) Due to the irregular size of wind turbine equipment, it is difficult to make reasonable layout on ships, resulting in low space utilization and low transportation efficiency. (2) During maritime transport, ships are affected by environmental factors such as wind and waves. The wind turbine equipment on the deck is prone to swaying, displacement, or even capsizing, which seriously affects transport safety. (3) Existing transport ships often need to rely on large port cranes when loading and unloading wind turbine equipment, which is complicated and time-consuming, increasing transportation and time costs.

[0020] The following combination Figures 1-5 This application will be described in further detail.

[0021] Example 1 This application discloses a multi-purpose transport vessel for transporting complete sets of high-power wind turbine equipment. (Refer to...) Figures 1-2 The vessel mainly consists of a hull 1, which, from top to bottom, includes bulwarks, a cargo deck 3, a through-type cargo hold 5, an inner bottom 2, and a hull bottom. The hull 1 is also equipped with an advanced power system and propulsion device. The power system has sufficient power to ensure stable speed and good maneuverability even in complex sea conditions when transporting wind turbine equipment.

[0022] The through-type cargo hold 5 is located in the middle of the interior of the hull 1. This through-type cargo hold 5 can also be used as a ballast water tank. During the loading of various parts of the wind turbine equipment, the height of the cargo deck surface can be adjusted through the ballast water system built into the hull 1. At the same time, the ballast water distribution can also be adjusted through the ballast water system to keep the hull 1 stable during loading.

[0023] The through-type cargo hold 5 is equipped with 18 removable second-level container covers 52. These second-level container covers 52, installed horizontally, divide the through-type cargo hold 5 into upper and lower levels to facilitate the loading of different types of cargo. Simultaneously, the second-level container covers 52 can be installed vertically as movable transverse bulkheads to provide localized load reinforcement based on cargo location. The installation method of the second-level container covers 52 can be adjusted according to actual usage needs, and the number of second-level container covers 52 can also be adjusted according to the dimensions of the through-type cargo hold 5.

[0024] The through-type cargo compartment 5 is also equipped with temperature control, dehumidification and shock absorption facilities, which can provide a suitable storage environment for the transformer, transmission chain, nacelle and hub of the wind turbine equipment, and reduce the occurrence of damage to the above components during transportation.

[0025] It should be noted that, in this embodiment, 6 of the 18 second-layer cabinet cover plates 52 have strong load-bearing capacity. The second-layer cabinet cover plates 52 with strong load-bearing capacity can be installed on the cargo deck 3 as the edge structure of the cargo deck 3 to increase the cargo carrying area of ​​the cargo deck 3 on the hull 1.

[0026] Please refer to Figure 3 In this embodiment of the application, nine through-type hatch covers 51 are installed on the hatch of the through-type cargo hold 5. The nine through-type hatch covers 51 are arranged sequentially along the length direction above the hatch of the through-type cargo hold 5, covering the internal space of the through-type cargo hold 5. The top surface of the through-type hatch covers 51 is flush with the top surface of the cargo deck.

[0027] Please refer to Figure 1 and Figure 2 To facilitate the transport and loading of wind turbine equipment, in this embodiment, two cranes 4 are installed on the starboard side of the cargo deck 3. The two cranes 4 can perform single-lift operations or tandem lifting operations. Both cranes 4 are equipped with a main hook and an auxiliary hook. The main hook has a lifting capacity of 700 tons and a lifting distance of 40 meters, while the auxiliary hook has a lifting capacity of 60 tons and a lifting distance of 56 meters. The main hook can be used to lift large and heavy wind turbine equipment components, while the auxiliary hook can be used to lift small parts of the wind turbine equipment.

[0028] Since the ship hull 1 has its own crane 4 on the deck, it can transfer and lift the various components of the wind turbine equipment without the need for the large crane 4 in the port, which can save transportation costs and time costs.

[0029] In this embodiment, the main wind turbine equipment is disassembled into the nacelle, hub, transformer, drive train, monopile 10, transition section, tower section 30, and wind turbine blades 20 for loading. The tower section 30 includes tower section one, tower section two, tower section three, and tower section four. Among them, the nacelle, hub, transformer, and drive train constitute the main wind turbine equipment, which are hoisted into the through-type cargo hold 5 by two cranes 4 for loading. In addition, the through-type cargo hold can also be used to store other precision equipment and instruments of the wind turbine equipment. The monopile 10, transition section, tower section one, tower section two, tower section three, tower section four, and wind turbine blades 20 are all loaded on the cargo deck 3.

[0030] It should be noted that, please refer to Figure 4 and Figure 5 In this embodiment, the transition section, tower section 1, tower section 2, tower section 3, and tower section 4 are all vertically mounted. The transition section, tower section 1, tower section 2, tower section 3, and tower section 4 have a high center of gravity and strict requirements for acceleration. Therefore, the transition section, tower section 1, tower section 2, tower section 3, and tower section 4 are arranged on the cargo deck 3 near the bow. In order to save space, the wind turbine blades 20 are stacked and arranged on the cargo deck 3 near the port side. The heavy and horizontally placed monopile 10 is arranged in the rear part of the cargo deck 3.

[0031] In order to securely fix the monopile 10, transition section, tower section 1, tower section 2, tower section 3, tower section 4, and blades to the cargo deck and prevent equipment displacement or damage due to ship swaying during transportation, in this embodiment, the surface of the cargo deck 3 is provided with a special cargo fixing and lashing system, which consists of a fixing base, lashing ropes, and fastening clamps.

[0032] It should be noted that in this embodiment, the transition section is transported vertically to the dock by a transport vehicle, while the first, second, third, and fourth tower sections are all transported horizontally to the dock by a transport vehicle.

[0033] This embodiment also proposes a loading method for a roll-on / roll-off (Ro-Ro) multi-purpose transport vessel that integrates the transport of complete sets of high-power wind turbine equipment. It mainly includes the following steps: Step S1: Load the main equipment of the wind turbine into the through-type cargo nacelle 5. The main equipment of the wind turbine includes a transformer, transmission chain, nacelle and hub. Step S2: The transition section and the tower section 30 are loaded onto the cargo deck 3 in sequence, and the transition section, tower section 1, tower section 2, tower section 3 and tower section 4 are loaded onto the cargo deck 3 in an upright position. Step S3: Roll up the monopile 10 using the SPMT trolley, lay the monopile 10 flat on the cargo deck 3, and set the monopile 10 along the bow and stern direction of the hull 1. Step S4: Install blade brackets at the middle and tail of the fan blades 20, so that the fan blades 20 are stacked on the blade brackets in a top-to-bottom direction.

[0034] Step S1 includes the following steps: Step S11: Use two cranes 4 to lift the nine through-type hatch covers 51 away from the hatch opening of the through-type cargo hold 5. Step S12: Arrange the second-layer cabinet cover plate 52 as a vertical support for the movable transverse bulkhead under the through-type cover 51 that contacts the single pile 10 bracket and fix it. Step S13: In the space where the moving transverse bulkhead is directed toward the bow, the first layer of cargo is arranged at the bottom of the through-type cargo hold 5 using a crane. Step S14: After the first layer of cargo is arranged, a second layer of cabinet cover 52 is laid in the through-type cargo hold 5 to separate an upper space above the first layer of cargo for arranging the second layer of cargo. Step S15: Arrange the second layer of cargo in the upper space using crane 4, and re-lift the hatch cover to the hatch of the through-type cargo hold 5.

[0035] Step S2 includes the following steps: Step S21: Transport the transition section to the dock and place it on a temporary pier for storage. Use any crane 4 to lift the transition section bracket from the dock to the cargo deck 3 and complete the binding. Use the crane 4 to lift the transition section and move it above the transition section bracket to complete the positioning. Connect the transition section to the transition section bracket with bolts. Step S22: Transport the tower section 30 to the dock and place temporary support blocks under the tower section 30. Use any crane 4 to lift the tower bracket from the dock to the cargo deck 3 and secure it. Connect the head and tail of the tower section 30 to two cranes 4 using rigging. After the hooks of the two cranes 4 are raised slightly at the same time, the crane 4 connected to the tail of the tower section 30 stops lifting, while the crane 4 connected to the head of the tower section 30 continues to lift, causing the tower to tilt and gradually adjust to an upright position. After the tower section 30 is erected, remove the rigging from the crane 4 connected to the tail of the tower section 30. Use the crane 4 connected to the head of the tower section 30 to move the tower section 30 to the corresponding tower bracket and fix the tower section 30 to the tower bracket with bolts. After step S23, when the transition section and tower section 30 are both loaded, the ship turns around and berths.

[0036] Step S3 includes the following steps: Step S31: Adjust the cargo deck 3 to be flush with the dock by adjusting the ballast water load; Step S32: Transport the monopile 10 to the dock using an SPMT trolley and install the monopile 10 bracket on the monopile 10. Step S33: Erect a gangway between the ship's side and the dock, and roll over the monopile 10 using an SPMT trolley. The SPMT trolley will then board the ship via the gangway and remain in position. The monopile 10 bracket will be secured to the cargo deck 3.

[0037] It should be noted that in some other embodiments, in step S3, some of the lighter monopiles can also be lifted by two cranes on the cargo deck together, which will not be limited or elaborated here.

[0038] Step S4 includes the following steps: Step S41: Install a blade tail bracket at the tail of the fan blade 20 and a blade middle bracket at the middle of the fan blade 20. Step S42: Transport the wind turbine blades 20 to the dock in sequence; Step S43: Connect any crane 4 to the blade tail bracket lug and the blade middle bracket lug using slings, and use the crane 4 to lift the wind turbine blade 20 to the position, and tie the blade tail bracket and the blade middle bracket to the cargo deck 3. Step S44: Stack the wind turbine blades 20 by crane 4 in a bottom-up stacking manner, connect and fix the blade tail bracket to the blade tail bracket, and connect and fix the blade middle bracket to the blade middle bracket.

[0039] Example 2 In this embodiment, the transport vessel also includes a data processing module located in the control compartment. The data output terminal of the data processing module is connected to a display screen inside the compartment. The data processing module can automatically calculate the hoisting sequence of the tower section 30 based on the input layout information of the tower section 30 and the information of the crane 4, and display the result on the display screen.

[0040] The tower section 30 layout information includes the positioning coordinates of the tower section 30 on the cargo deck 3 and the tower section 30 number. The crane 4 information includes the coordinate data of the two cranes 4.

[0041] In this embodiment, a two-dimensional coordinate system is established on the surface of the cargo deck 3 with the starboard side of the hull 1 as the X-axis and the edge of the cargo deck 3 near the stern as the Y-axis. Before loading, relevant technicians pre-plan the loading positions of the tower sections 30 based on the safety distance of the tower sections 30, the width of the wind turbine blades 20, and the positions of the two cranes 4 on the cargo deck 3, and pre-number the tower sections 30 to be loaded at each position.

[0042] It should be noted that the safety distance is determined based on the space occupied by the cargo securing and lashing system on cargo deck 3 and the space interval requirements between adjacent cargo securing and lashing systems.

[0043] The data processing module automatically calculates the hoisting sequence of tower section 30 based on the layout information of tower section 30 and the information of crane 4. The data processing method includes the following steps: Step A: Calculate the blockage factor of each tower segment 30 in the layout. The blockage factor is a score used to evaluate the blockage caused by the tower segment 30 to the adjacent tower segments 30. Step B: Calculate the hoisting priority for each tower section 30 based on the blockage coefficient; Step C: Output the loading order of tower sections 30 in descending order of priority, and display the loading order on the display.

[0044] In step A, the specific method for calculating the blockage coefficient of tower section 30 is as follows: Step A1: Define the hoisting shielding sector area of ​​tower segment 30Ti: For each tower segment 30Ti, calculate the vector Vi from tower Q to tower segment 30Ti; determine the sector angle by rotating vector Vi clockwise by θ2 and counterclockwise by θ2, where θ is the sector angle of the hoisting shielding sector area, and θ is an empirical parameter (θ is 30° in this embodiment); use the maximum hoisting distance of crane 4 as the radius of the hoisting shielding sector area; Step A2: Determine whether the remaining tower sections 30 are located within the hoisting shielding sector area of ​​tower section 30Ti by checking the angle and distance. Step A3: Calculate the number of tower sections 30 located within the hoisting shielding sector area of ​​tower section 30Ti. The number of tower sections 30 located within the hoisting shielding sector area of ​​tower section 30Ti is the blockage degree of tower section 30Ti.

[0045] In step A2, the angle check for the remaining tower sections 30 is as follows: calculate the vector Vj between the crane 4Q and the tower section 30Tj, calculate the angle between Vi and Vj, and if the angle between Vi and Vj is less than θ2, then it is determined that the tower section 30Tj is located within the hoisting shielding sector of the tower section 30Ti; otherwise, the tower section 30Tj is not located within the hoisting shielding sector of the tower section 30Ti.

[0046] In step A2, the distance check for the remaining tower sections 30 is as follows: calculate the straight-line distance Li between tower section 30Ti and crane 4Q, and calculate the straight-line distance Lj between tower section 30Tj and crane 4Q. If Lj > Li, it means that the path for hoisting Tj must pass through the area where Ti is located, so Ti will block Tj; if Lj < Li, then the opposite is true.

[0047] For tower section 30Ti, if there is blockage in angle check and / or distance check, it is determined that tower section 30Ti is blocking tower section 30Tj. The number of Tj can reflect the blockage coefficient of tower section 30Ti. For tower section 30 with a higher blockage coefficient, it is prioritized for hoisting and loading, which can improve the efficiency of loading tower section 30.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
