Sesam Wind software

Sesam Wind software

is a tailor-made solution for structural strength analysis of offshore wind turbine structures. It can be used for conceptual and detailed design of the primary structure, as well as for design of secondary steel such as boat landings and J-tubes. Besides this, Sesam can perform other lifecycle analysis such as transportation and lifting.

What you get

  • Sesam Wind is powered by Sesam, based on decades of experience in engineering of offshore structures
  • Applicable for analyses of wind turbine structures and supporting major rules and standards as IEC61400-3, DNV-OS-J101 and DNVGL-RP-0005 (DNV-RP-C203)
  • Interactive 3D modeller supporting combined beam and shell models
  • Use for any complexity of structure, from monopiles and tripods to jacket structures

One complete system

In offshore wind turbine design, engineers need a solution for structural strength analysis that can account for the combined effect of wind and hydrodynamic loads. Sesam Wind is tailor-made to address the challenges in wind turbine design – one complete system covering all aspects of offshore installations.
