“…However, Larsen et al found that the blade pitch control strategy could induce negative damping effects on pitch motion under certain conditions (Larsen and Hanson, 2007). Therefore, Iino et al (2012) improved the control strategy to reduce the effects of negative damping and verified the performance of control system by an experiment. Guo et al (2012) also investigated the effects of individual blade pitch controller on global pitch motion based on a proportional-integral-derivative controller.…”

Due to the existence of rotor and tower, the floating offshore wind turbine (FOWT) is subjected to greater wind heeling moment than the conventional floating platform, which would cause significant pitch motion and bring great challenge to the structural safety and power generating efficiency. Moreover, the dynamic cable used for power transmission is sensitive to the horizontal motion of floating platform. Thus, it is essential to inhibit the pitch and horizontal motions of FOWT. The FOWT is connected to the seabed by a mooring system to resist the motions, while the conventional mooring system mainly resists the horizontal motion. In this article, an innovative type of mooring system was proposed to resist the pitch and horizontal motions simultaneously, by dividing the fairleads into two groups at different depths. The motion responses and structural loads of FOWTs were calculated and compared under the effects of the conventional and innovative mooring systems. In addition, the restoring forces and moments of two mooring systems were also given to better verify the motion-inhibiting performances. According to the results, the innovative mooring system was able to significantly reduce the pitch and surge motions of FOWT.

“…A preliminary assessment of the dynamic behavior of a 5-MW braceless semisubmersible offshore wind turbine with three columns and two fully submerged pontoons is presented for selected environmental operational conditions that correspond to a deep water offshore site with depth 200 m [6]. To simulate the pitching motion of floating platform, it used onshore wind turbine model with inflow with oscillating wind speed that simulates relative wind speed change from wind turbine's fore-aft pitching motion [7]. Particulars of this research are to examine the unique dynamic response characteristics of the thrust-matched blade system, which includes a better performance-matched rotor relative to the geometry-matched blade system [8].…”

Abstract. In this paper, a comprehensive study is performed on the dynamic response of an offshore wind turbine for multiple load condition. The aim is to evaluate to what extent the multiple loading affects the wind turbine for running. Based on consistent flexible multi-body models calibrated to multiple loading functions of a monopole embedded in a linear viscoelastic soil layer, fully coupled aero-hydro-elastic simulations are conducted in the nonlinear multi-body code. Correlation of wind speeds and waves is derived on basis of wind-wave scatter diagrams from China south sea. Changes of the multiple loading, the response of an offshore wind turbine are shown to be critical for the fatigue damage equivalent moment that may change with more than 20% for parked wind turbine conditions.
