Description

Technical Field

[0001] The present invention relates to the technical field of operation and maintenance vessels, and in particular to a novel bottom-sitting wind power operation and maintenance vessel which is anti-adsorption and self-floating. Background Art

[0002] Offshore wind power operation and maintenance vessels are important means of transportation for the construction, operation and maintenance of offshore wind farms, and are special vessels used for the operation and maintenance of offshore wind turbines.

[0003] At present, most offshore wind farms are located in shallow waters. Shallow waters are shallow at low tide, and even the bottom of the water is exposed above the water. Due to the limitation of ship draft, for safety reasons such as ships hitting the bottom and running aground, when the tide is low at the offshore wind farm, in order to prevent the ship from hitting the bottom and running aground, the wind power operation and maintenance ship needs to leave the wind farm in time and return to the dock to wait. After the wind farm rises and the water depth meets the requirements for safe navigation and operation, it will return to the wind farm for operation. During the low tide and high tide time window, the ship needs to travel back and forth between the dock or wind farm. The ship's back and forth travel wastes the precious operation window period and also increases fuel consumption. In addition, when sailing, the crew needs to be on duty, which increases the workload of the crew. Summary of the invention

[0004] In order to solve all or part of the above technical problems, the present invention provides a new type of wind power operation and maintenance ship with anti-adsorption and self-floating bottom-sitting. When the offshore wind farm is at low tide or low tide, the wind power operation and maintenance ship can be stably and safely seated on the seabed or mudflat of the wind farm to stay on duty, avoiding the ship's round trip between the wind farm and the port at different tide levels; when the wind farm is at high tide, the wind power operation and maintenance ship can use anti-adsorption technology to automatically float and sail for operation, preventing the ship from being adsorbed by silt and unable to float due to long-term bottom-sitting. It avoids the ship's round trip between the wind farm and the port at different tide levels, reduces the non-operating time of the ship, and increases the operating efficiency of the wind power operation and maintenance ship.

[0005] The technical solution provided by the present invention is as follows:

[0028] See also Figure 1 The present invention provides a new type of wind power operation and maintenance vessel with anti-adsorption and self-floating bottom-sitting. The operation and maintenance vessel is of catamaran design and includes a safe bottom-sitting system. The safe bottom-sitting system includes a hull 1 and a hull 2. The hull 1 and the hull 2 ​​are connected by a connecting bridge 20. The hulls 1 and 2 are provided with an anti-adsorption system. The anti-adsorption system includes a compressed air supply component, a compressed air pipeline and a plurality of nozzles 3. The plurality of nozzles 3 are respectively arranged on both sides of the bottom of the hull 1 and the hull 2. The nozzles 3 are connected to the compressed air supply component through compressed air pipelines.

[0029] like Figure 1 As shown, the bottom of hull 1 and hull 2 ​​is designed to be V-shaped, the top of the connecting bridge 20 is flush with the top of hull 1 and hull 2, the bottom of hull 1 and hull 2 ​​is reinforced by reinforcing ribs or reinforcing plates, and the nozzles 3 are distributed on both sides of the bottom of the V. The catamaran type of the present invention can provide a firm support for the ship when it lands on the bottom to prevent the ship from capsizing, and the reinforcement design of the bottom structure is to prevent the hull from being deformed and damaged when it lands on the bottom.

[0030] Optionally, the operation and maintenance vessel also includes a ballast flotation system, which includes a ballast water pump 17, a ballast water tank 12 and a ballast water pipeline. Multiple ballast water tanks 12 are distributed at the bow and stern of hull 1 and hull 2. The ballast water pump 17 is arranged on the pipeline connecting the ballast water pipeline and the ballast water tank 12. The ballast water pump 17 is used to inject seawater into the ballast water tank 12 or discharge seawater in the ballast tank.

[0031] like Figure 2 As shown, the operation and maintenance vessel also includes a duty support system, which includes an air-cooled generator set 9, a fresh water supply module 11 and a fuel supply module 10, and the fuel supply module 10 supplies fuel to the air-cooled generator set 9. When the wind power operation and maintenance vessel is on duty at the bottom, the duty support system can provide the wind power operation and maintenance vessel with consumables such as electricity, fresh water, and fuel during the duty period.

[0032] Optionally, hull 1 and hull 2 ​​are symmetrically arranged about the connecting bridge 20, and multiple nozzles 3 are evenly distributed on both sides of the bottom of hull 1 and hull 2.

[0033] like Figure 3 As shown, the compressed air supply assembly includes an air compressor 13 , an air bottle group 14 , and a first pipeline 7 , which are arranged on the deck of hull 1 or hull 2 ​​. The air compressor 13 is used to store compressed air in the air bottle group 14 .

[0034] A second pipeline 8 is also distributed in the cabin of hull 1 or hull 2, and the second pipeline 8 is connected to the nozzle 3. The air bottle group 14 transports compressed air to the nozzle 3 through the first pipeline 7 and the second pipeline 8 and the compressed air is sprayed out by the nozzle 3.

[0035] A plurality of valves 4 are provided on the first pipeline 7 and the second pipeline 8 .

[0036] Optionally, the ballast water pipeline includes a ballast water injection pipeline 16, a ballast water discharge pipeline 18 and a third pipeline 19, the third pipeline 19 is connected to all ballast water tanks 12, the ballast water pump 17 is arranged on the third pipeline 19, and the ballast water injection pipeline 16 and the ballast water discharge pipeline 18 are arranged on the third pipeline 19 on both sides of the ballast water pump 17. Figure 3 As shown, the ballast water pump 17 may be installed in the nacelle 15 .

[0037] Optionally, a plurality of valves are provided on the ballast water injection pipeline 16 , the ballast water discharge pipeline 18 and the third pipeline 19 .

[0038] When the sea area of ​​the wind farm is at low tide or has completed ebb tide, as the water depth decreases, the catamaran wind power operation and maintenance ship will slowly sit on the seabed or mudflat. Hull 1 and hull 2 ​​can firmly support the ship to remain on the seabed to prevent the ship from capsizing due to unstable center of gravity. During the period when the ship sits on the bottom for duty, the air-cooled generator set 9 provides electricity for the ship, the fuel supply module 10 provides fuel for the air-cooled generator set 9, and the fresh water supply module 11 provides daily fresh water for the ship. The duty support system provides the ship with consumables such as electricity and fresh water during the period when the ship sits on the bottom for duty. When the sea area of ​​the wind farm still has a certain water depth and the ship cannot sit completely on the bottom, the ballast water pump 17, ballast water pipeline and valve can be used to inject ballast water into the ballast water tank 12 to increase the deadweight of the ship so that the ship can sit completely on the bottom. Due to the weight of the hull, the hull will slowly sink into the silt 6 on the seabed below the waterline 5. As time goes by, the air between the hull and the silt 6 is gradually squeezed out, forming a vacuum, and the silt is adsorbed onto the hull.

[0039] When the tide rises in the sea area of ​​the wind farm, as the water level rises, the draft of the ship will also increase, and the buoyancy of the ship will gradually increase. However, due to the vacuum formed between the hull and the silt 6, the hull is subject to a great adsorption force and cannot float up by itself. Choose a suitable time before high tide, use the air compressor 13 and the air bottle group 14, and provide compressed air to the nozzle 3 through the first pipeline 7 and the valve 4, and use the compressed air to destroy the vacuum on the surface of the hull and reduce the adsorption force of the surrounding silt. Use the ballast water pump 17, ballast water pipeline and valve to discharge the ballast water in the ballast water tank 12 out of the ship, reduce the deadweight of the ship, and allow the ship to float up by itself. As the water depth increases and the safe navigation conditions are met, the wind power operation and maintenance ship can sail freely.

[0040] The above is only the best specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application shall be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
