It gives the turbine a hub height of 135 metres and a tip height of 198.5 metres.
There were plans to install the E-112 predecessor offshore, but Enercon chose to steer clear of the offshore sector, while the development of segmented blades for the E-126 eased onshore transport and installation logistics.
Power rating 7.58MW Rotor diameter 127m Drivetrain Direct-drive IEC Class IA === Eight years have passed since Chinese manufacturer Ming Yang signed an agreement with German design consultancy Aerodyn to build its radical downwind two-blade offshore turbine under licence for the Chinese market, but the project has yet to progress to serial production.
Power rating 8MW Rotor diameter 180m Drivetrain Medium-speed geared IEC Class l B === First seen in 2011 as a 6MW unit with a rotor diameter of 120 metres, Siemens twice since upgraded the direct-drive offshore turbine for a power rating of 8MW with an extended rotor diameter of 154 metres.
The operational life of the 6MW machine kicked off in 2015 with the inauguration of Dong's 210MW Westermost Rough project off the north-east coast of England.
The big brother looks well placed to keep the German company on top.
Power rating 8MW Rotor diameter 154m Drivetrain Direct-drive IEC Class l B === Developed from a 6MW machine unveiled in 2007, Enercon's E-126 is the only onshore turbine to qualify for this list.
A prototype with a 140-metre rotor diameter was installed in China in the second half of 2014.
Aerodyn aims to sell the turbine in other markets outside China, and the company is now working on an 8MW variant with a 168-metre rotor diameter, which it showed in concept form at the 2014 Hamburg Wind Fair in Germany.
The turbine has also been chosen to power part of the nearby Walney Extension project, due to go online in summer 2018.
