Siemens Gamesa SG 11.0-200 DD


The SG 11.0-200 DD has evolved from generations of proven offshore direct drive technology.

With serial production planned for 2022, the powerful 11 MW offshore turbine will offer both high energy yield and reliability.

Technical specifications:

IEC classS
Nominal power11,000 kW
Rotor diameter200 m
Blade length97 m
Swept area31,400 m²
Hub heightSite specific
Power regulationPitch-regulated, variable speed

The SG 11.0-200 DD with its increased rotor diameter to 200 meters and 97 meter long blades will deliver up to 9 percent more AEP than its predecessor.

Technological highlights:

  • Components that are wear-prone in offshore turbines are reduced with every new generation of Siemens Gamesa direct drive technology.
  • The high wind ride through (HWRT) system is a breakthrough in stabilizing energy output. When the wind speed is higher than 25 meters per second, wind turbines usually shut down for protect themselves. Turbines equipped with the HWRT system will slowly ramp down power output instead, enabling smoother production ramp-down and thereby a more reliable electrical grid.
  • The development of IntegralBlade technology enables each fiberglass-reinforced epoxy blade to be cast in one piece. This process eliminates weaker areas at glued joints and produces blades of optimum quality, strength, and reliability.
  • Turbine sensors continuously transmit data to the Siemens Gamesa diagnostic center, enabling the early detection of anomalies and preventing potential failures. By analyzing vibration patterns, we can optimize your service plan and anticipate repairs before serious damage occurs.
