- 摘要： In recent years, the offshore wind energy has increased in popularity due to the demand for renewable energy. Being built in a very dynamic environment, the nonlinear wave and current loads on offshore wind turbines are required to be investigated for design. The wave and current kinematics were calculated by the model that the wave propagates on a linear shear current which was developed by Dalrymple based on the stream function wave theory. The wave and current loads were calculated based on the Morison equation. For the engineering application purpose, some problems such that the wave and current kinematics models, the wave and current combination schemes in statistics, and the free surface's influences on wave and current loads were discussed. At the end, the nonlinear results were compared with linear results to verify the calculation correctness.
