Hundreds of the world’s largest turbines will be used for offshore wind projects in the UK. The 6 MW German made turbines will be built at large-scale wind farms, including the country’s Round 3 projects. 

The turbines, which German firm Siemens has developed, have the “world’s largest” rotor blade, measuring 75m. Siemens will supply and service 300 turbines for Danish firm DONG Energy’s offshore projects in the UK. This includes Round 3 projects, which is a UK initiative to develop offshore wind across nine zones. The order has a capacity of 1.8 GW. 

The Siemens’ SWT-6.0-154 gearless direct drive turbine has a rotor diameter of 154m and a swept area of more than 18,600sqm, which the company says is equivalent to the size of approximately two-and-a-half football fields. The company claims that the turbine can supply 6000 households with electricity. 

Siemens said: “The new 6 MW wind turbine is designed specifically for offshore use – taking in to account serviceability, and 50 per cent less components, including fewer rotating parts. All this contributes to assuring the important reliability of the offshore technology.”

DONG Energy will install two of the turbines at the Gunfleet Sands offshore site for testing later this year. The rest will be installed off the UK coastline between 2014 and 2017. 

Carsten Krogsgaard Thomsen, acting CEO of DONG Energy, said: "The agreement will enable DONG Energy to install a significantly larger and more efficient wind turbine from 2014 compared to what we know today. The agreement is a key element of our objective to significantly expand offshore wind and strengthen our position as market leader within offshore wind. For DONG Energy, this is an important step towards further industrialisation and will contribute to the enhanced competitiveness of offshore wind." 

The target for 2020 in the UK is 18 GW of offshore wind energy, which equates to around 18 per cent of the UK's electricity demand.
