3. RAMBOLL WIND & TOWERS - AUGUST 2014
TUBULAR ONSHORE JACKETS - EXCELLENT FOR LARGE HUB HEIGHTS
WHY LARGER HUB-HEIGHTS?
The wind speed is higher
 Increased power production (~proportional to the height)
The turbulence intensity and shear of the wind is lower
 Lowers the fatigue damage from fluctuations in the wind
Large parts of potential wind sites covered by forest
 These areas require larger hub-heights
