摘要：	In this paper, the dynamic response of a 5-MW barge-type offshore floating wind turbine (OFWT) in combined wind-wave conditions is numerically investigated with a newly developed integrated analysis tool.In this tool, we use an efficient and high-fidelity hydrodynamic model developed in one of the authors' previous work [2] to calculate the wave load.To account for the wind load, the present horizontal axis wind turbine is simplified as a "uniform actuator disk" in this tool.For the restoring force by mooring lines, the quasi-static method is implemented.By combining these models with rigid body dynamics, the present integrated analysis tool is thus developed.In order to validate the present tool, it is used to predict the natural frequency of the pitch DOF of the barge-type offshore floating wind turbine.After validation, the integrated analysis tool is used to investigate the effects of wave frequency and wave height on the power generation, the mean surge position, wave loads, and the bending moment at the root of the tower.Obvious nonlinear effects of wave frequency and wave height are observed on these interested parameters through the present study.
