Dynamic analysis of tripod offshore wind turbine under wind and wave loads considering water-strucure interaction

AbstractApplying wind energy as a source of renewable and alternative fuels is very important. Given that the sea is the more stable and fast winds, so most of the countries that have access to the sea, are in particular attention to the installation of wind turbines in the sea. New problem arise with the installation wind turbines in the sea, which is due to additional sea states such as wave and current loads. Therefore modeling and analysis of offshore wind turbines under wave and wind loads is essential. In this research the offshore wind turbine with tripod platform has been modeled and analyzed under wave and wind excitations. Then it considers the effects of wave and wind parameters on the response of strucuture. The results show that increasing the waves and the wind parameters does not increase the response of the structure necessarily. Also effect of these parameters on the structural response is different.
