| Abstract: |
| Due to the coupled disturbances of waves, ocean currents, and other factors, traditional equipment used for grouting construction of offshore wind power monopile foundations suffers from problems such as low accuracy, poor adaptability, and insufficient green intelligence. To address this issue, this study develops a particle swarm optimization-whale optimization algorithm (PSO-WOA) optimized multimodal proportional-integral-derivative (PID) adaptive compensation technology, along with supporting modular equipment, following the technical route of algorithm optimization-equipment upgrading-field verification. The algorithm incorporates a multisource data fusion disturbance prediction model, and the parameters of a three-level control architecture comprising fundamental PID, fuzzy adaptive control, and feedforward compensation are optimized using a hybrid PSO-WOA algorithm. Under extreme sea conditions, the overshoot and adjustment times are reduced by 62.3% and 61.5%, respectively, compared to traditional PID. In addition, delay compensation decreases the additional deviation by 60%-70%. The equipment features a modular design that accommodates a working radius of 5-30 m and a height of 10-20 m, and it includes a dual-mode control system (local and remote) with a focus on green design. Field tests conducted in water depths of 35 m and wave heights of 1.0-2.5 m demonstrate that the grouting position deviation is only 2.4 ±0.4 cm (a reduction of 76.9%), energy consumption is reduced by 29.2%, and construction efficiency is improved by 66.7%. The equipment remains stable under extreme sea conditions (wave height of 3.0-3.5 m) while achieving qualified compactness. This technology overcomes the bottlenecks of construction accuracy and environmental sustainability in offshore grouting, making it suitable for stratum reinforcement scenarios involving shallow sea fixed foundations, such as offshore wind power monopile foundations and offshore platform pile foundations. |
