Offshore wind deep-water technology development

Researchers are advancing offshore wind engineering to enable installations in deeper waters. In July, a TU Delft team introduced perforated monopile concepts, using high‑resolution simulations and machine‑learning surrogates to optimise openings that lower wave loading while maintaining structural strength. Their work also highlighted the growing importance of coupled dynamics between large monopiles, jack‑up vessels, and installation equipment as monopile sizes increase.

Later in the month, studies reported additional innovations. High‑fidelity simulations showed that the rocking and surging of floating offshore wind turbines can boost electricity output by 2‑5 % compared with fixed‑bottom designs, leveraging wave‑induced motion to increase aerodynamic lift. Concurrently, researchers proposed a cable‑stay reinforcement for large monopile turbines, adapting bridge‑engineering techniques to enhance flexural stiffness, damp resonance, and mitigate buckling under combined seismic, wind, and wave loads. Both lines of research aim to expand offshore wind capacity into deeper, more challenging marine environments while improving energy yield and structural resilience.
