DNV is launching new design software for ultimate strength and fatigue analysis of offshore wind turbine structures - Sesam GeniE Wind.

Building on 40 years as a design tool for engineering floating and fixed offshore structures, the new Sesam module addresses the wind industry’s need to model the combined effect of wind and wave loads. The new tailor-made module, GeniE Wind, can be used for design and fatigue analyses of wind turbine substructures. Its analysis functionality complies with the DNV offshore standard DNV-OS-J101 Design of Offshore Wind Turbines. Fatigue and ultimate strength calculations can be performed based on direct time-series simulations of combined wave and wind loads. The 3D modelling functionality in GeniE allows traditional beam modelling of the slender parts while the complex transition between the wind tower and supporting structure can be accurately modelled using shell elements.
