Today, offshore wind power is already a well established component of the power supply mix in northern Europe. There are open areas off the coasts with excellent wind conditions offering enormous potential. Wind turbines with a generating capacity of 4.3GW are already installed in this region. In order to further reduce the costs for offshore wind power, innovations and industrialization are vital.
Siemens has designed the gearless wind turbine with a capacity of 6MW especially for offshore deployment. Since 2010, the company has also held a 49% stake in A2SEA which provides services for the construction of offshore wind power plants. A2SEA, in which DONG Energy holds the remaining shares, has now deployed a new generation of offshore installation vessels for the first time off the British coast.
Together with its partner DONG Energy, Siemens has at the same time pulled off a double pioneering feat: with the very first deployment of the new installation vessel, two Siemens wind turbines of the 6MW class complete with rotor star were installed in the record time of under 24 hours each in the offshore demonstration project Gunfleet Sands III.
