Abstract:   (258 Views)
The purpose of this study is to provide a more accurate and practical method than static and spectral methods to assess the offshore wind turbines that are loaded with both wave and wind time history, the structure is evaluated by increasing the load intensity in successive steps to the stage of failure and the performance of the platform in different wave patterns are investigated. In this study, incremental wave-wind analysis is used, which is similar to the IDA method in earthquakes. In conclusion, it is observed that the responses of the structure under different loads of waves will be so similar. Short-term irregular waves in this study are called constrained new waves, which is a very good alternative to irregular waves with a long time history, jointed wave-wind data are used, all modeling and interaction relations between the wave and the structure and Wind power is done in opensees software.
