Abstract
As the ocean environment is more complex than the land environment, the offshore wind turbines especially the floating types generally suffer significant structural loads. In this study, in order to carry out the accurate simulation and analysis for the dynamic characteristics of a barge-type floating wind turbine, a detailed turbine model including the complete drivetrain is constructed. Additionally, the structural responses of the wind turbine are mitigated by using a single-degree of freedom tuned mass damper (TMD) system installed in the platform. In order to achieve the ideal response mitigation effect, a parametric study on the TMD configuration is carried out. Based on a new co-simulation model combining multi-body model and external control codes, the turbine model coupled with the TMD is then simulated under the combined wind and wave. The results demonstrate the effectiveness of the designed TMD on mitigating the structural responses of the barge-type floating wind turbine.
