- Offshore wind farms Access, Design philosophy, Selection of wind turbine / Due diligence, Integration Farm management and Grid Codes, Beatrice
- Offshore wind climate and atmospheric marine boundary layer. Wind profile. Extreme wind speed. Velocity pressure. Turbulence characteristics. Peak velocity pressure.
- Wind forces on slender structures. Static loads. Force coefficients. Dynamic loads due to turbulence, vortex shedding and wake effects.
- Wind forces and wind effects on wind turbines.
- Measures for wind-induced vibration mitigation.
- Monitoring of wind speed and structural response.
Learning outcome
- a general introduction to the field of offshore wind energy
- an introduction to modelling of static and dynamic wind loads on various types of structures. In particular, wind forces on slender structures and the associated wind-structure interaction will be discussed.
- knowledge of design characteristics, operational performance, and maintenance of wind turbines. Focus is put on big turbines with offshore potential.
