Siemens wins another service order for the Veja Mate offshore wind farm

Siemens has received an order for the maintenance and upkeep of the Offshore Substation (OSS) and turbine substructures of the Veja Mate offshore wind farm. Siemens will install 67 six MW class wind turbines for the 400 MW offshore wind farm and connect it to land with the BorWin2 DC grid connection. This grid connection can transmit a total of just under 800 MW of clean wind energy

Siemens will implement a complete service concept to meet the maintenance needs of projects far offshore such as the Veja Mate offshore wind farm. The exact scope of supply includes the scheduled maintenance and upkeep of the OSS, the 67 transition pieces of the wind turbines, as well as the inspection of their underwater structures. A transition piece is the part that lies between a monopile foundation and the tower of an offshore wind turbine.


Siemens will also build and operate an OCC in Hamburg, equipped with SCADA software provided by Veja Mate for the operational control of the offshore wind farm. The company will be responsible for the entire offshore logistics, correcting faults on site and using EPCI contractor supplied spare parts and consumables during warranty.

For the wind turbines, Siemens will provide a highly advanced logistics concept, tailored specifically for far-shore projects, that uses both a helicopter and a specially designed, purpose-built service operation vessel (SOV). To ensure increased energy production this concept allows maintenance work to be carried out at almost all times irrespective of the weather conditions or wave height.

The Veja Mate offshore wind farm is being built in the German waters of the North Sea. The wind turbines in the SWT-6.0-154 series will be installed at ocean depths between 39 and 41 meters starting in January 2017. To date, Siemens has installed four HVDC grid connections and four offshore wind farms in the German waters of the North Sea alone. Furthermore, Siemens will supply wind turbines to five offshore wind farms which are currently under construction in the German North and Baltic Sea.
