Jack-up vessel Seajacks Leviathan was employed to install the final blade of 88 turbines at the site.
The second jack-up vessel GMS Endeavour is completing the erection of the Siemens 3.6MW turbines over the last five months.
Scira Offshore Energy, a joint venture company Statoil and Statkraft owns the wind farm, where the 46 turbines are currently delivering electricity to the national grid.
The remaining turbines are in various stages of mechanical and electrical completion while work will also continue on the cable burial.
The wind farm had been generating power since August 2011 and will commence full operations by 2012.
