Back in 2011, when Siemens Gamesa launched its 8MW wind turbine platform the machine was 6MW. It says a lot that the manufacturer has managed to squeeze so much out of it.
It is one of the biggest wind turbines in the world and it an in terms of orders is set to be the most-installed offshore turbine in terms of capacity.
Siemens 8MW facts
- Power: 8MW
- Rotor: 154-metres
- Environment: offshore
The 8MW model was initially 6MW was then upgraded to 7MW. Siemens announced this at the EWEA Offshore conference in Copenhagen in 2015.
The latest upgrade incorporates changes inside the nacelle as well as a larger rotor.
Speaking about the upgrade in January, Siemens said: “Since the higher rating will be achieved with only a few component upgrades, including a new cooling concept and a new control system, customers will again benefit from key value drivers including fast time-to-market and low risk.”
Siemens 8MW offshore wind turbine – a multi-faceted platform
The company said Siemens said the platform, comprising 6MW and 7MW turbines, has completed 100 years of combined operation.
The machine has mostly been installed in northern Europe.
One of the latest projects to use the turbine is RWE Innogy’s Galloper project, which is located off England’s east coast.
The project uses 6MW versions of the SWT 8MW wind turbine platform. However, these have been boosted to 6.3MW.
RWE builds Galloper
RWE announced the first power was produced by the project in November 2017. Installation began in May, illustrating how quickly offshore projects can now be installed.
“We have generated in record time having built the offshore part of the project in a single year, which is a fantastic achievement,” said Innogy project director Toby Edmonds.
The turbine is the world’s second-largest wind turbine according to Windturbiner’s Biggest Wind Turbines in the World feature.

Hywind and the 8MW windmill
Siemens 8MW is also installed on the Hywind floating wind farm off the coast of Scotland. The project is the largest of its type and the only one to use a next-generation turbine.
Five Siemens SWT 6.0-154 turbines are installed on a spar buoy foundations. These are held upright by the weight of ballast, with the steel cylinder tethered to the seabed by a three-point mooring.
