PO505: Ballast Optimization in Floating Wind Turbines Through Differentiable Deep Learning Surrogate Models
Guillermo Rodríguez Llorente, AI engineer, HI Iberia
Abstract
Ballast systems are critical for maintaining stability, minimizing tilt, and reducing fatigue in floating wind turbines which use them. Conventional control strategies rely on iterative simulations or are too computationally expensive for real-time optimization. In the ePROA project, we developed a differentiable surrogate model framework to address this challenge, embedding sea dynamics within a neural operator structure capable of gradient-based optimization. By exploiting differentiability, the system computes optimal ballast configurations directly, adjusting to changing metocean conditions with unprecedented speed. The surrogate was trained on synthetic datasets generated with OrcaFlex across a wide range of sea states, enabling the optimizer to generalize to diverse operating scenarios The optimized ballast control reduces tilt, alleviates structural loads, and maximizes energy production. Integrated into the digital twin environment, the optimizer provides operators with real-time recommendations via a Grafana interface, translating complex optimization results into actionable ballast adjustments. This development represents a significant advance in the operational efficiency of floating wind, but also control in other floating platforms, offering a pathway toward more resilient, reliable, and cost-effective offshore energy.
