Description

Technical Field

[0001] The present invention belongs to the technical field of offshore wind power engineering, and in particular relates to a ring layout method for an underwater data center combining offshore wind turbine pile foundation scour suppression with ecological aquaculture. Background Art

[0002] As the global energy structure transforms towards clean and low-carbon, offshore wind power, as a core area of ​​renewable energy, has been rapidly developed and widely used around the world in recent years. By 2025, the installed capacity of offshore wind power will continue to grow, becoming a key technology for addressing climate change and energy crises. However, the pile foundations of offshore wind power facilities are prone to severe scouring under natural forces such as ocean currents, waves and typhoons, resulting in loss of seabed soil, decreased stability of pile foundations, and even structural damage, shortened engineering life and safety hazards. This not only increases maintenance costs, but also limits the long-term sustainable development of offshore wind power. In response to this problem, existing technologies have proposed a variety of solutions, but all have significant limitations.

[0003] At present, scour protection in the existing technology mainly relies on engineering reinforcement methods, such as laying concrete slope protection, caissons or anti-scour cushions around pile foundations to reduce scour impacts by increasing the physical resistance and stability of the seabed. These methods can delay the scour process to a certain extent, but their high construction and maintenance costs, especially in typhoon-prone sea areas, often lead to engineering failures due to frequent natural disasters, and significantly reduce economic benefits. In addition, these hard structures may change the seabed topography, destroy the marine ecosystem, affect the habitat and reproduction of aquatic organisms, and even cause local ecological imbalance, making it difficult to achieve the goal of harmonious coexistence with the environment.

[0004] In recent years, ecological restoration and bioprotection technologies have gradually attracted attention. Some studies have attempted to deploy artificial reefs, shell deposits or aquatic plants to attract aquatic organisms to attach and use their secretions and sediments to enhance the stability of the seabed, while repairing the marine ecology. However, the effects of these methods are limited, especially in the severe scouring environment caused by strong currents or typhoons. The ecological structure has a weak ability to resist scouring, and the construction and maintenance costs are high, making it difficult to generate significant economic returns in the short term. In addition, these technologies are not closely integrated with the engineering needs of offshore wind power pile foundations, and the application scenarios are limited, making it difficult to meet the actual needs of large-scale engineering projects. At the same time, underwater data center (UDC) technology, as an emerging innovative solution, has shown great potential in the field of data processing in recent years. For example, Microsoft's "Project Natick" project deploys data centers on the seabed, using seawater direct cooling and renewable energy (such as wind power and tidal power) for power supply, significantly reducing energy consumption and carbon footprint, and the server failure rate is also much lower than that of land facilities. This technology achieves efficient operation and low-latency services through sealed pressure vessels (such as steel pipes with a diameter of 2.8 meters and a length of 12 meters) and modular design, especially in applications close to coastal cities. However, existing underwater data center technology mainly focuses on data processing efficiency and reliability, and the deployment method is usually linear or point-like, which cannot meet the scour protection requirements of offshore wind power pile foundations.

[0005] It can be seen that the deployment method of underwater data centers in the existing technology needs to be further improved. Summary of the invention

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] It is understandable that the connection relationship described in this application refers to direct or indirect connection. For example, the connection between A and B can be either a direct connection between A and B or an indirect connection between A and B through one or more other electrical components. For example, A and C can be directly connected, and C and B can be directly connected, so that A and B are connected through C. It is also understandable that the "A connects B" described in this application can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0032] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0033] The technical solution of the present application is further described in detail below in conjunction with the accompanying drawings.

[0034] The "inclination angle" mentioned in the present invention specifically refers to the UDC module being arranged at an inclination angle of 15°, which refers to the angle between the longitudinal axis of the module and the normal of the seabed, and the inclination direction is against the flow direction of the water flow (i.e. the top of the module is facing the upstream of the water flow).

[0035] The "UDC module" mentioned in the present invention has a cabin body that is a sealed pressure vessel made of high-strength steel or composite materials, with a diameter of 2.5 meters and a length of 12 meters. Each UDC module weighs about 24 to 36 tons, and a polyurea coating is applied on the outer surface of the cabin body.

[0036] The "heat dissipation system" mentioned in the present invention is designed to efficiently cool the internal servers and use the residual heat (35-40°C) to form a heat plume area. The heat dissipation system uses seawater direct cooling to directly remove the heat generated by the server using the low temperature characteristics of seawater. The specific heat dissipation principle is: using seawater as a cooling medium, removing the heat from the server through natural convection and forced convection, and after cooling by seawater, the outlet water temperature is controlled at 35-40°C.

[0037] The structure of the heat dissipation system is as follows: it includes a cooling chamber and a heat sink (copper base, area 2m 2 ), the servers in the cabin are directly connected to the heat sink, the bulkhead of the cooling cabin is in direct contact with seawater, the bottom and top are respectively provided with a water inlet (diameter 0.1m) and a water outlet (diameter 0.08m), and the water inlet and outlet are respectively provided with a filter screen with an aperture of 0.5mm. The seawater is driven through the cooling cabin by external ocean currents and thermal convection, without the need for an additional water pump.

[0038] After the seawater in the cooling cabin absorbs the heat from the server, the temperature rises from 20°C to 35-40°C and is naturally discharged through the outlet. The outlet is designed to be open, and the hot water diffuses through natural convection and external water flow to form a thermal plume area with a diameter of about 30m. The water temperature rises by 2-3°C and the water flow rate is 0.15m / s. The inner wall of the cooling cabin is coated with a 0.2mm thick PTFE coating for corrosion prevention to prevent seawater corrosion and biological attachment. The filter screen is cleaned regularly to avoid clogging.

[0039] The present invention mainly utilizes the combination of a ring-shaped UDC and an ecological breeding system to reduce the scouring of wind turbine pile foundations. Based on this technical concept, the following further describes a ring-shaped layout method of an underwater data center that combines offshore wind turbine pile foundation scouring suppression with ecological breeding.

[0040] Combination Figure 1 and Figure 2As shown, the underwater data center of the present invention includes but is not limited to submarine cables, submarine composite optical cables, several UDC modules, etc., such as submarine cables connected to wind farms located at sea, using wind energy for power supply. The submarine composite optical cable can transmit the acquired data to the data center to facilitate real-time understanding of the submarine situation. As a major innovation of the present invention, the layout of the UDC module 4 is specifically as follows: several UDC modules are arranged in the circumferential direction of the wind turbine pile foundation with the wind turbine pile foundation 1 as the center; assuming that the diameter of the wind turbine pile foundation is d, the annular diameter formed by several UDC modules is 5d~15d (determined according to different pile driver diameters and the number of UDC layouts); the spacing between adjacent UDC modules is 0.1d~0.3d; the inclination angle of each UDC module is 10~20°; the purpose of such a setting is to induce water flow to form a reverse secondary vortex, reduce the intensity of the main vortex, reduce the maximum flow velocity around the pile foundation from 3m / s to 1.2m / s, and reduce the depth of the scouring pit by 42%-47%.

[0041] Each UDC module includes a sealed cabin, a cooling system, a server and a gravity anchor for fixing the cabin. The gravity anchor is a triangular fixed frame structure. A connecting ring is set on the top of the gravity anchor, which is connected to the cabin through the connecting ring and the bottom is inserted into the seabed 5.

[0042] The average water temperature of the annular area formed by the UDC module is increased by 2 to 3°C, forming a thermal plume slow flow area with a diameter of about 30 meters. The water flow velocity is maintained at 0.15m / s, attracting aquatic organisms (such as oysters and kelp) to live in groups. Therefore, the present invention sets an ecological breeding system above the annular area. The ecological breeding system includes an algae plant area located in the upper layer, a mollusk breeding area located in the middle layer, and a sedimentation area located in the lower layer. The algae plant area is arranged 0 to 5m away from the water surface, the mollusk breeding area is arranged 5 to 10m away from the water surface, and the sedimentation area is the seabed area below several UDC modules.

[0043] The plants planted in the algae area are kelp, agaricus, blue algae or green algae, and the plants are properly fixed by a fixing rope 2, one end of which is fixed on the wind turbine pile foundation 1, and the other end is connected to the fixed structure. Ammonia nitrogen is absorbed by planting algae such as kelp or agaricus. The mollusk breeding area in the middle layer includes a breeding cage 3 and a mollusk located in the breeding cage. The mollusk is not limited to oysters; the mollusk breeding area is used for calcification and carbon fixation. Artificial reefs, abalone, scallops or sea urchin bottom seeding are provided in the sedimentation area to promote sedimentation. The pore diameter of the artificial reef is 2 to 5 cm, and the pore volume accounts for 0.3 to 0.4 of the total volume of the artificial reef.

[0044] In the ecological aquaculture system, the adhesive protein secreted by oysters combines with the sediment, and the shear strength is increased from 15kPa to 50kPa. The kelp root system forms a biological grid, reducing the critical value of the sediment start-up velocity to 0.15m / s. The closed-loop resource flow UDC waste heat is stored using zinc oxide phase change materials, and aquaculture waste is recycled through high-temperature oxidation. Abandoned oyster shells are crushed and pressed into porous reef blocks and placed in high-risk areas for scour, reducing the flow rate by 40%.

[0045] The present invention will be further described below in conjunction with specific embodiments:

[0046] Embodiment 1:

[0047] It was implemented in a sea area in the East China Sea with a water depth of 20 meters and an average annual water flow velocity of 0.12m / s. The diameter of the wind turbine pile foundation was 5 meters and the seabed was sandy sediment.

[0048] The specific operations are as follows:

[0049] Step 1: Water depth and topography measurement: Use a multibeam echo sounder to measure the water depth and seabed topography, confirm that the seabed slope is <5° and the sediment thickness is >5 meters, to ensure that it is suitable for the placement of the UDC module.

[0050] Current and wave analysis: The annual average water velocity, maximum flow velocity and wave parameters are recorded by acoustic Doppler current meters to provide data support for the ring layout design.

[0051] Seabed soil characteristics: Use gravity samplers to collect seabed samples and analyze soil type, particle size and bearing capacity to confirm suitability for gravity anchor fixation.

[0052] Water quality and ecological baseline: Use underwater drones to record water quality parameters and aquatic organism distribution to provide a reference for ecological aquaculture.

[0053] Equipment preparation: prepare marine engineering vessels, cranes, ROVs, UDC modules and submarine cables.

[0054] The second step is to conduct performance testing on the UDC module, testing the module's sealing, server operation and heat dissipation performance in a simulated underwater environment on land. The test lasts 72 hours.

[0055] Gravity anchors are pre-installed at the bottom of the UDC module with a pull-out force of >20 tons, suitable for sandy seabeds.

[0056] A cable interface is reserved at the bottom or side of the UDC module. The cable length is 50m and armored optical fiber cable is used.

[0057] The third step is to install the gravity anchor and UDC module. The gravity anchor is made of Q235 steel, and the surface of the anchor body is coated with epoxy resin coating, which is resistant to seawater corrosion.

[0058] A connection ring is set on the top of the gravity anchor for connecting with the UDC module. UDC module bottom design: A connection seat is reserved at the bottom of the UDC module, and the connection seat is embedded with bolt holes for fixing the gravity anchor.

[0059] Connection operation: Place the gravity anchor under the UDC module at the onshore manufacturing plant or on the deck of the transport ship, and align the connection ring with the connection seat at the bottom of the module. Use high-strength bolts to fix the gravity anchor connection ring through the bolt holes of the connection seat. The bolt tightening torque is 200N·m to ensure a firm connection. After the connection is completed, use a portable tensile tester to test the connection strength and confirm that the pull-out force is >20 tons, which meets the requirements for seabed fixing.

[0060] Protective measures: Apply waterproof sealant to the connection parts to prevent seawater from penetrating into the connection parts and causing corrosion. Check the overall center of gravity of the UDC module and the gravity anchor to ensure that there is no tilt during the lowering process.

[0061] Step 4: Transportation of UDC modules and gravity anchors

[0062] The quay crane is used at the port, and a special fixing frame is set on the deck of the transport ship. The module is fixed with steel cables and anti-skid pads. During transportation, check the fixing status to avoid loosening.

[0063] Step 5: Lowering and positioning of UDC modules and gravity anchors

[0064] After the UDC module is connected to the gravity anchor, it is lowered to the seabed as a whole. The specific steps are as follows:

[0065] Offshore positioning:

[0066] After the transport ship arrives at the target sea area, the DP2 system is used to lock the center position of the wind turbine pile foundation.

[0067] 12 installation points are marked by USBL and sonar, with a circular diameter of 10D (for example, if the pile foundation diameter is 5 meters, the circular diameter is 50 meters) and a spacing of 0.2D (1 meter).

[0068] UDC module lowering: The UDC module and the gravity anchor are hoisted as a whole using a ship-borne crane, and the hoisting cable is equipped with a guide device to control the lowering trajectory. The lowering speed is controlled at 0.5m / s, and slowed down to 0.1m / s when approaching the seabed to ensure a soft landing of the gravity anchor and avoid impact on the seabed. The ROV monitors the module position and attitude in real time to confirm that the positioning error is <10cm.

[0069] Attitude adjustment: After the gravity anchor contacts the seabed, adjust the inclination of the UDC module. Confirm that the bottom of the gravity anchor is completely in contact with the seabed, the anchor claw is embedded in the seabed, and the pull-out force is >20 tons.

[0070] Cable connection: The ROV connects the cable interface of the UDC module to the submarine cable, which is laid along the seabed, covered with a protective layer of gravel, and connected to the wind farm control center.

[0071] Step 6: Cooling system operation and ecological farming system deployment

[0072] Cooling system starts: After the UDC module is powered, the server runs, seawater enters through the water inlet of the cooling cabin, absorbs the heat of the heat sink, and the temperature rises from 20°C to 36-38°C and is discharged from the water outlet.

[0073] Ecological aquaculture system deployment: Upper layer (0-5m): install floating aquaculture nets and plant kelp. Middle layer (5-10m): suspend oyster cages around. Bottom layer (seabed): arrange artificial reefs (porosity 60%) and plant abalone.

[0074] Step 6: Operation monitoring and maintenance

[0075] Operation monitoring: After 6 months of operation, the depth of the scour pit decreased, the aquaculture output increased, and the data processing efficiency improved. Maintenance: Use ROV every 6 months to check the fixed status of the gravity anchor, clean the attachments at the inlet and outlet, and ensure the heat dissipation efficiency.

[0076] It should be noted that the present invention is applicable to sea areas with a water depth of 10 to 50 meters, and is particularly suitable for areas with high scour risks or frequent typhoons, such as the East China Sea and the South China Sea.

[0077] Parts not described in the present invention can be implemented by referring to the existing technology.

[0078] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application.
