Vattenfall awarded Siemens Energy an order for 72 Model SWT-4.0-130 wind turbines for its new Sandbank offshore wind farm. The project is being erected 90 kilometers west of the island of Sylt off the German North Sea coast. A service plan for the project will generate synergy from its close vicinity to DanTysk offshore wind farm, utilizing joint operations to drive down the maintenance costs of both projects. Vattenfall has contracted Siemens to perform maintenance services on the Sandbank installations for an initial period of five years. Service operations will center on a service operation vessel (SOV) specially designed for these deployments. Construction is scheduled to commence in summer 2015.
