Cable-stay reinforcement could improve offshore wind turbine seismic resilience

University of Technology Sydney researchers modeled a cable-stay reinforcement for offshore wind turbines and validated it in simulation.

For 15-MW monopile-based turbines under combined seismic, wind, and wave loads, the design reduced vibration, stress, ovalisation, yielding, and buckling.

The approach could improve safety and reliability for offshore wind farms in earthquake-prone regions and serve as a cost-effective retrofit.

Published in Ocean Engineering, the findings also point to longer asset life and lower replacement costs.
