Description

Technical Field

[0001] The present invention relates to the field of offshore wind power construction, and more specifically, to a method for installing an offshore wind turbine in a deep soft soil covering layer and a data analysis model. Background Art

[0002] With the continuous growth of the global demand for renewable energy, offshore wind power, as a clean and efficient form of energy, has received extensive attention and rapid development; in traditional offshore wind turbine installation, the pile legs are usually inserted into the seabed through hydraulic hammering or vibratory pile driving techniques. However, in a deep soft soil covering layer, the high viscosity and low strength of the soft soil result in a large frictional resistance on the pile legs during the penetration process, reducing the hammering efficiency.

[0003] For example: "A pre-tensioned pile-anchor combined foundation for a shallow covering layer seabed and its construction method" disclosed in the Chinese invention patent (application number: 202110055208.3), its specification discloses: including a wind turbine, a tower barrel, and a pile foundation connected in sequence from top to bottom, the bottom of the pile foundation is vertically embedded in the soft soil layer and contacts the rock layer; a plurality of anchor rods are fixedly connected to the side wall of the pile foundation at circumferential intervals through a connecting device, and the other end of each anchor rod passes through the soft soil layer and is embedded in the rock layer and fixedly connected to the rock-embedded anchoring end. In the present invention, the vertical force borne by the pile foundation is mainly borne by the friction force of the surface soil and the rock and soil layer at the bottom of the pile, and the horizontal load is borne by the soil around the pile, the anchor rods, and their rock-embedded anchoring ends. The bearing capacity is stable, facilitating construction and installation, and having a large stiffness, ensuring good stability of the upper structure of the offshore wind turbine; the above patent can prove the defects existing in the prior art.

[0004] Therefore, we make improvements in this regard and propose a method for installing an offshore wind turbine in a deep soft soil covering layer and a data analysis model. Summary of the Invention

[0048] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0051] Embodiment 1

[0052] Please refer to Figure 1 and Figure 3 , an installation method of an offshore wind turbine with a thick soft soil cover layer, which includes the following steps:

[0053] Data collection and preparation: Collect field geological data and environmental data, select a hoisting ship and equipment, and prepare pile legs, hammering equipment, cooling devices, and solidifying materials;

[0054] Pile leg installation: Pretreat the pile legs to reduce frictional resistance, use the layered hammering method to dynamically adjust the hammering energy, and at the same time inject solidifying materials during the hammering process to enhance the soil bearing capacity, ensuring that the pile legs penetrate to the designed depth and maintain verticality;

[0055] Wind turbine hoisting: Hoist the wind turbine tower, nacelle, and blades in sections onto the pile legs, ensure the alignment accuracy and levelness, and monitor the environmental parameters in real time during the hoisting process to ensure operation safety;

[0056] Late - stage inspection and commissioning: Check the installation quality of each component of the wind turbine, commission the electrical and control systems, conduct a trial run, and clean the operation site.

[0057] Further, as Figure 1 and Figure 2 shown, data collection and preparation include the following steps:

[0058] Data collection: Collect geological data of the site area (soil layer distribution, soil hardness, water content, etc.) to determine the depth and characteristics of the soft soil layer. For example, the depth of the soft soil layer is 20 - 30 meters, the soil hardness is 5 - 10 MPa. Collect environmental data (wind speed, wave height, tide, etc.), and select a time window with a wind speed lower than 10 m / s and a wave height lower than 1.5 meters for operation;

[0059] Prepare equipment and materials: Select a crane ship with a lifting capacity ≥ 1000 tons, equipped with a dynamic positioning system (DP), and prepare pile legs (length ≥ 50 meters), hydraulic hammering equipment (hammering energy ≥ 2000 kJ), liquid nitrogen cooling device, curing agent (cement slurry), etc.

[0060] Further, as Figure 1 and Figure 3 shown, pile leg installation includes the following steps:

[0061] Pile leg pre - cooling: Apply liquid nitrogen to the bottom of the pile leg and cool it to - 50 °C to form a hardened layer, reducing the frictional resistance during the hammering process, which takes about 1 hour; The pre - cooling hardens the surface of the pile leg, significantly reducing the frictional resistance of the soft soil to the pile leg, improving the hammering efficiency. During the penetration process of the pile leg, the disturbance to the soft soil is small, reducing the risk of soil liquefaction and settlement. By reducing the frictional resistance and soil disturbance, the penetration process of the pile leg is more stable, reducing the risk of pile slipping and improving the installation accuracy;

[0062] Initial hammering: Lift the pile leg to the target position, start the hydraulic hammering equipment, set the initial hammering energy to 500 kJ. In the soft soil layer (depth 0 - 20 meters), use low - energy hammering (500 - 800 kJ) to avoid excessive disturbance to the soil, and monitor the inclination of the pile leg in real - time to ensure that the inclination ≤ 1°;

[0063] Layered hammering: When the pile leg enters the hard soil layer (depth 20 - 30 meters), increase the hammering energy to 1500 kJ to ensure the penetration efficiency. Every 10 hammerings, check the penetration depth and inclination of the pile leg to ensure that the penetration speed ≥ 0.5 m / min and the inclination ≤ 1°;

[0064] Soil solidification: During the hammering process, inject cement slurry (water - cement ratio 0.5) around the pile leg to locally harden the soft soil and improve the soil bearing capacity. The solidification range has a diameter of about 5 meters and takes about 2 hours;

[0065] Final penetration: When the pile leg approaches the design depth (about 40 meters), reduce the hammering energy to 1000 kJ to ensure penetration accuracy. Finally, check the elevation of the pile top to ensure that the penetration depth error ≤ 10 cm.

[0066] Further, as Figure 1 and Figure 4 shown, the wind turbine hoisting includes the following steps:

[0067] Tower installation: Hoist the tower onto the pile leg and use a hydraulic adjustment device to ensure the alignment accuracy (deviation ≤ 2 cm). The installation of each section of the tower takes about 1 hour, and the total time is about 4 hours.

[0068] Nacelle and blade installation: Hoist the nacelle to the top of the tower and use a level to ensure the levelness of the nacelle (deviation ≤ 0.5°). Then hoist the blades in sequence. The installation of each blade takes about 1 hour, and the total time is about 3 hours. During the hoisting process, monitor the wind speed and wave height in real time to ensure that the wind speed ≤ 12 m / s and the wave height ≤ 2 meters.

[0069] Embodiment 2

[0070] Further optimize the installation method of the offshore wind turbine in the deep soft soil covering layer provided in Embodiment 1. Specifically, as Figure 1 and Figure 5 shown, the later inspection and commissioning include the following steps:

[0071] Structural inspection: Check the installation quality of the pile leg, tower, nacelle and blades to ensure that each component meets the design requirements. Use a laser rangefinder to check the verticality of the tower (deviation ≤ 0.1°).

[0072] System commissioning: Commission the electrical system and control system of the wind turbine to ensure its normal operation. Conduct a trial run and check the power generation performance of the wind turbine (output power ≥ 5 MW).

[0073] Environmental restoration: Clean the operation site and restore the marine environment.

[0074] Embodiment 3

[0075] Further optimize the installation method of the offshore wind turbine in the deep soft soil covering layer provided in Embodiment 1 or 2. Specifically, as Figure 6 shown, the data analysis model for the installation of the offshore wind turbine in the deep soft soil covering layer includes:

[0076] During the data collection stage, detailed geological information such as the structure of the upper-middle foundation soil in the field area, soil layer distribution, and soil mechanical properties is collected to ensure the accuracy and integrity of the data, providing a reliable basis for subsequent analysis. Environmental parameters such as wind speed, wind direction, wave height, tide, and seawater temperature are collected in real-time using meteorological and ocean monitoring equipment. The specifications and performance parameters of the lifting vessel and lifting equipment are collected, including lifting capacity, stability, and operating range. Key parameters during the lifting process are recorded, such as the lifting method, pile driving method, hammering energy, and number of hammer blows.

[0077] During the data preprocessing stage, data from different sources are integrated to form a unified data format and storage method, and the data is standardized.

[0078] Z-score standardization, formula:

[0079] Z = (X - μ) / σ

[0080] Where X is the original data, μ is the mean of the data, and σ is the standard deviation of the data.

[0081] Min-Max standardization, formula:

[0082] X ， = (X - X- min ) / (X- max - X- min )

[0083] Where X is the original data, Xmin is the minimum value in the data, and Xmax is the maximum value in the data.

[0084] The influence of different dimensions and data ranges on the analysis results is eliminated, and the data set is divided into a training set, a validation set, and a test set. The training set is used for model training, the validation set is used for model tuning, and the test set is used for evaluating model performance.

[0085] During the data analysis and simulation stage, based on the collected environmental data, ship and machinery data, and lifting process data, the lifting process is simulated. Considering different soil layer characteristics, environmental factors, and ship and machinery performance, the optimal installation time and process are obtained. According to the soil layer characteristics and lifting parameters, the possibility of pile slipping is predicted, and preventive measures are proposed to reduce the risk of pile slipping.

[0086] Logistic regression formula:

[0087] P(Y = 1|X) = 1 / (1 + e ^ (-(β0 + β2 * X2 + … + βn * Xn)))

[0088] Among them, P(Y = 1|X) is the probability that event Y occurs when the input variable X is given, β0, β1,..., βn are coefficients obtained through logistic regression training, and X1, X2,..., Xn are input variables;

[0089] Automatically adjust the hammering force according to the hardness of different soil layers to ensure the smooth progress of the pile driving process and improve the hoisting efficiency;

[0090] Polynomial regression formula:

[0091] F = β0 + β1*H + β2*H^2

[0092] Among them, F is the predicted hammering force, H is the soil hardness, and β0, β1, β2 are coefficients obtained through polynomial regression training; Comprehensively consider meteorological, marine environment, ship and machine performance, and geological conditions to determine the optimal hoisting time window to ensure the safety and efficiency of hoisting operations.

[0093] In the scheme generation stage, generate detailed information such as hoisting sequence, hoisting point position, hoisting attitude, etc., to provide a clear basis for hoisting operations; Recommend the hammering force of the pile leg in soil layers at different depths according to soil layer characteristics and environmental factors; Determine the optimal installation time window to ensure the successful progress of hoisting operations.

[0094] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; It can be a mechanical connection, an electrical connection, or communication with each other; It can be directly connected, or indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
