Siemens Gamesa Installs First 115-Metre Blade on SG 14-236 DD Offshore Wind Turbine Prototype

Siemens Gamesa has installed the first of the three 115-metre blades on the SG 14-236 DD offshore wind turbine prototype at the Danish national test center for large wind turbines in Østerild.

The SG 14-236 DD features a 236-metre diameter rotor, with a 43,500 m2 swept area, approximately the size of 6.1 standard football pitches.

With a capacity of up to 15 MW, the SG 14-236 is based on Siemens Gamesa’s existing turbine – the SG 14-222 DD.

Thye B115 blades for the SG 14-236 DD prototype were manufactured at Siemens Gamesa’s plant in Aalborg.

The blades are the final pieces needed to complete the installation of the SG 14-236 DD prototype in Østerild, following the installation of the tower and the nacelle last year.

The 236-metre rotor with blades based on the IntegralBlade® technology will enable the SG 14-236 DD to produce more than 30 per cent Annual Energy Production (AEP) compared to the SG 11.0-200 DD, Siemens Gamesa said.

The SG 14-236 DD model will be commercially available in 2024 and has so far been selected as a preferred option for the Norfolk Vanguard and Boreas wind farms offshore the UK, as well as for the MFW Bałtyk II and MFW Bałtyk III wind farms in the Polish Baltic Sea.
