Sažetak
The present study addresses the effects of concurrent wind, wave and currents action on the dynamic response of a single floating offshore wind turbine supported on a tension-leg platform. The structural response of the wind turbine was determined for a set of different wind, wave and currents conditions. This was analyzed on a small-scale wind-turbine model in the Wind Wave Current (WWC) Tank at Newcastle University, UK. The dominant frequency in the dynamic response of the wind-turbine model to regular waves for the surge displacement (in the main flow direction) is dominated by the waves. The current flow modifies the amplitude of the spectrum of the dynamic response due to regular waves for the sway displacement (laterally to the main flow direction). The response amplitude operator (RAO) for the surge displacement indicates that the frequencies outside the wave-frequency range are excited as well, while the addition of the currents and wind damped the second-order hydrodynamics effects.
