• Identification of wave drift forces on a floating wind turbine sub-structure with heave plates and comparison with predictions 

      Fonseca, Nuno; Nybø, Synne Hoggen; Rodrigues, José Miguel; Gallego, Aitor; Garrido, Carlos (Chapter; Peer reviewed, 2022)
      The paper presents empirical quadratic transfer functions (QTFs) of the horizontal wave drift loads on a turret moored floating wind turbine in operational and in severe sea states. Comparison between the empirical results ...
    • Wave Drift Forces and Low Frequency Damping on the Exwave FPSO 

      Fonseca, Nuno; Stansberg, Carl Trygve (ASME Proceedings | Offshore Technology;OMAE2017-62540, Chapter, 2017-06-25)
      A method is followed in the present analysis to estimate realistic surge and sway wave drift force coefficients for the Exwave FPSO. Model test data is used to identify the difference frequency wave exciting force coefficients ...
    • Wave Drift Forces and Low Frequency Damping on the Exwave Semi-Submersible 

      Fonseca, Nuno; Stansberg, Carl Trygve (ASME Proceedings | Offshore Technology;OMAE2017-62539, Chapter, 2017-06-25)
      The paper presents realistic horizontal wave drift force coefficients and low frequency damping coefficients for the Exwave semi-submersible under severe seastates. The analysis includes conditions with collinear waves and ...
