Sofia Offshore Wind Farm, owned by RWE on Dogger Bank in the central North Sea, has now installed 80 of its 100 Siemens Gamesa SG 14‑222 DD turbines, moving the 1.4 GW project closer to start‑up. Once fully commissioned, Sofia is expected to generate enough electricity to meet the equivalent demand of 1.2 million UK homes.
Installation is being carried out by Cadeler’s Wind Peak, which installed the first turbine in March 2025 and transports components for six turbines per voyage from Hull. The vessel is supported by the IWS Seawalker service‑operation vessel (SOV), which provides logistics and crew transfer during the offshore construction campaign.
Each turbine stands 252 metres above sea level, with 108‑metre blades sweeping an area of 39,000 m2 per rotor.
Around half of Sofia’s 100 turbines use recyclable blades, with all of those units installed in 2025 as part of the UK’s first large‑scale offshore deployment of this technology.
