DIMSELO

In this project we investigated how different models for waves and wave loads impacted the calculated dimensioning extreme and fatigue loads for 10 MW offshore bottom fixed wind turbines.

10MW monopile offshore wind turbine in short crested waves
  •  Work:
    • Develop new wave modelling methods that are both more realistic then those used and also of suitable for engineering use.
    • Develop 10MW reference monopile and jacket turbines for Dogger Bank conditions
    • Compare existing and project-developed wave and wave load models with respect to dimensioning fatigue and extreme loads for offshore wind turbines
    • Instigate how different wind field models approved in the standards influence dimensioning fatigue loads
    • Developed validated methods for modelling short crested waves and wave loads in shallow waters with CFD
  • Main innovations:
    • Developed methods and software that for the first time made it possible to model highly realistic second order short crested waves at engineering speed
    • Developed a new and more realistic way to model extreme waves
  • Industry benefits
    • More realistic engineering speed models for waves and wave loads
    • Knowledge about how calculated fatigue and extreme loads vary with used wave and sea lods models
    • Developed technologies available for industry in IFE’s simulation tool 3DFloat
  • Project partners:
  • Project type: KPN project financed by the industry partners and the ENERGIX program at the RCN
