The Zaratan vessel last night completed the installation of the 288MW Meerwind offshore wind farm in the German North Sea, contractor Seajacks told Recharge.
The wind farm consists of 80 of Siemens' 3.6MW turbines and is located 23km north of the German island of Helgoland.
Bad weather last autumn delayed completion of the plant, Jens Assheuer, managing director of WindMW, which is building the project and will operate it, said late last year.
The €1.2bn ($1.65bn) Meerwind project had suffered grid-connection delays, and also had to face costs of between €10m and €15m to clear unexploded debris from World War II weapons lying at the bottom of the sea.
WindMW is owned 80% by US private equity firm Blackstone, while developer Windland Energieerzeugung holds another 20%.
Next to Meerwind and the Nördlicher Grund offshore project that Blackstone plans to equip with 64 6MW turbines, the investment firm is eying a possible third German offshore project, WindMW’s Assheuer told Recharge last year.
