Siemens Gamesa Introduces DD Flex Offshore Wind Technology


Siemens Gamesa Renewable Energy (SGRE) has expanded its product portfolio with the launch of the new DD Flex concept and the SG 11.0-193 DD Flex offshore wind turbine.

Built on the current largest offshore wind turbine in the SGRE fleet, the SG 11.0-193 DD Flex can reach a capacity of 11 MW under specific site conditions.

“Digitalization allows us to increase the capacity of our current largest machine to 11 MW, boosting its annual energy production, while keeping the levelized cost of energy down,” says Andreas Nauen, CEO of the Siemens Gamesa offshore business unit.

The SG 11.0-193 DD Flex offshore wind turbine features a 193-meter diameter rotor utilizing the 94-meter long Siemens Gamesa B94 Integral Blades. Constant digital observations are processed by the control system, increasing capacity up to 11 MW. The upgraded turbine has been created based on SGRE’s expertise within its offshore direct drive technology, gained over five product generations since being launched in 2011.

Vattenfall and SGRE recently announced that they are extending the Hollandse Kust Zuid (HKZ) turbine supply to now also include HKZ 1&2 in addition to HKZ 3&4. The wind farm is planned to be fitted with 140 units of the upgraded version of the direct drive offshore turbine.
