In 2009, 199 wind turbines in eight separate offshore wind farms were installed and grid connected in European waters, totaling 577 MW of new capacity - a 54% increase on 2008 installations. The eight offshore wind farms which were wholly or partially connected during 2009 range in size from 2.3 MW (Hywind, Norway) to 209 MW (Horns Rev 2, Denmark).The average size of wind turbines installed offshore during 2009 was 2.9 MW.

 

 

 

Of the 199 wind turbines installed and grid connected during 2009, 146 were Siemens turbines (2.3 MW and 3.6 MW), 37 were Vestas turbines (3 MW), 10 were WinWind turbines (3 MW) and six were Multibrid turbines (5 MW) (see figure 1.1). In addition, six REpower turbines (5 MW) were installed but not grid connected¹ (see figure 1.2).

 

 

  

 

  

DONG Energy was the leading developer/utility during 2009 in terms of installations, installing 313 MW of the 577 MW. DONG Energy was followed by E.ON Climate & Renewables and RWE Innogy (see figure 1.2).

 

 

  

 

  

The majority of the substructures installed during 2009 were monopiles – 88% in total. Only two farms installed during 2009 used gravity foundations and one used tripods² (see figure 1.3).



Importantly, the first full scale turbine was installed using a floating foundation/substructure, in a water depth of 220m.

 

1 The six REpower turbines and their foundations are therefore not included in the analysis undertaken in this document.

2 The six REpower turbines at Alpha Ventus using jacket foundations are excluded from this analysis as the turbines were not

grid connected by 31 December 2009.
