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.
- 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
