Karmakar, D., Bagbanci, H. and Guedes Soares, C. (2013), “Joint probability distribution of extreme loads of spar and semi-sibmersible floating wind turbines using the Environmental Contour Method”, Proceedings of the 32nd International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2013), 9-14 June, Nantes, France

In the present study, the environmental contour method is used to estimate the long-term joint probability distribution of extreme loads for different types of offshore floating wind turbines. The study is carried out in order to predict the out of plane bending moment (OoPBM) loads at the blade root and tower base moment (TBM) loads for a 5MW offshore floating wind turbine of different floater configuration. A spar and semisubmersible offshore floating wind turbines are considered for the analysis. The FAST code is used to simulate the wind conditions for various return periods and the design loads of various floating wind turbine configurations. The present study predicts long-term design loads for wind turbines without requiring excessive computational effort.
