Floating Offshore Wind Turbines Gain Power from Wave Motion, New Study Shows

Recent high‑fidelity simulations indicate that the rocking and surging of floating offshore wind turbines in deep‑water waves can increase electricity output by 2 % to over 5 % compared with rigid, fixed‑bottom designs. The motion boosts aerodynamic lift as the platform pitches into the wind, refreshing airflow and raising relative wind speed.

Separate research from the University of Technology Sydney proposes a cable‑stay reinforcement for 15‑megawatt monopile turbines. The system, adapted from bridge engineering, adds high‑tensile steel cables and struts to increase flexural stiffness, dampen resonance, and prevent ovalisation of the tower under combined earthquake, wind and wave loads. Simulations show the reinforced design markedly reduces stress and the risk of catastrophic buckling.

Both studies address key challenges for expanding offshore wind into deeper seas and seismically active regions, offering engineering solutions that could improve energy yield and structural resilience.
