A comparative study about the effects of linear, weakly and fully nonlinear wave models on the dynamic response of offshore wind turbines

A novel numerical package capable of predicting the nonlinear loads acting on offshore wind turbines exposed to nonlinear sea states has been recently proposed in (Marino, Lugni, & Borri 2013). The model reproduces the structural response by coupling a fully nonlinear wave kinematic solve with a hydro-aeroelastic simulator of the entire system (Jonkman & Buhl 2005). The computational efficiency is guaranteed by a domain decomposition strategy such that the fully nonlinear numerical wave solver is invoked only on special subdomains.
