Asghari, M. and Guedes Soares, C. (2015), “Investigation of wind speed effect on dynamics of a semisubersible offshore floating wind turbine”, Renewable Energies Offshore, Guedes Soares, C. (Ed.), Taylor & Francis Group, London, UK, pp. pp. 665-672
The paper presents an analysis of floating wind turbine motion responses in regular and irregular waves. This paper aims to investigate how wind speed affects the motions of a typical floating wind turbine platform. It is shown that the wind speed can alter the natural frequency and the amplitude in surge and pitch motions.A reference turbine with a semisubmersible platform is simulated in this paper. The response amplitude operator of such a turbine is determined with the simulation of both regular and irregular waves for various uniform wind profiles. The blades pitch angle control is considered for having a realistic simulation so to have maximum possible power generation. The white noise spectrum, which has a wide band uniform power spectral density, will be implemented for evaluation of the platform motions at different wind speeds.A response amplitude operator evaluation based on irregular waves which is numerically cost saving will be calibrated and validated by comparison with results obtained for regular waves. Finally, the platform motion will be analysed by deriving the wind speed and wave frequency joint response amplitude operator.
