Overview

Numerical simulation demonstrates minimal power loss in tension-leg platform wind turbines under ocean waves, suggesting platform motions do not degrade offshore wind farm efficiency.

Key Points

  • To evaluate how ocean wave-induced platform motions affect the power generation and wake dynamics of single and clustered tension-leg platform wind turbines.
  • Coupled large-eddy simulations (LES) of atmospheric and rotor dynamics with tension-leg platform (TLP) motions for NREL 5 MW wind turbines.
  • Modeled fully developed ocean waves using the Pierson–Moskowitz spectrum across the entire operational wind speed range.
  • Compared average power output and wake structures between dynamic floating platforms and rigid stationary baselines.
  • Induced motions of the tension-leg platforms exerted only a minor influence on average power output for both single and arrayed wind turbines across all operational wind speeds.
  • Significant wake modifications caused by platform motions remained confined to the near-wake zone, leaving downstream turbine locations largely unaffected.
  • Atmospheric turbulence fluctuations substantially exceeded the amplitude of wave-induced platform motions, explaining the lack of significant downstream wake and power disruption.
