Norway, Nov. 27 -- DNV, the independent energy expert and assurance provider, has developed three advanced time-domain methods for analysing the structural performance of floating offshore wind turbines. Now available in DNV's Sesam software, the methods simulate how turbines respond to wind and wave forces in harsh offshore environments.Analysing floating wind turbines is highly complex, as combined wind and wave loads must be captured using large, detailed structural models. Time-domain analysis, used to model a structure's behaviour over time under changing conditions, is typically required, but demands substantial computing time, even on high-performance systems. By calculating how the structures move and react at every time step, engin...
