External conditions

 

High wind speeds have a positive effect on yields, but offshore WTs are exposed to factors other than the wind - such as waves, currents and ice drifts.

 

Offshore WTs are therefore exposed to greater forces and must be more robustly designed overall. In addition to strengthening of mechanical components, increased protection against corrosion is also necessary. Corrosion endangers the surfaces of tower, nacelle and rotor blades, and electrical contacts.
