B.offshore Conducts Alpha Ventus Substation Maintenance

B.offshore GmbH has completed maintenance work on the offshore substation of the Alpha Ventus offshore wind farm in Germany.

B.offshore’s scope of work in the 12-month project included the installation of two new tank containers on the platform of the offshore substation, as well as the design and installation of new solutions for the emergency power system.

According to the German company, the original steel tanks were replaced with plastic tanks made of polyethylene (LLD-PE). The two offshore containers are each fitted with three CUBE tanks and have a combined capacity of 15,000 liters.

The company was also in charge of developing and implementing a solution to integrate the new system with the existing substation control technology, managed by EWE OSS Offshore Service & Solutions, who coordinated the work.

Deutsche Offshore-Testfeld- und Infrastruktur GmbH & Co. KG (DOTI), the operator of the wind farm, recently completed acceptance tests for the new solution, b.offshore said.

The Alpha Ventus wind farm comprises six Adwen M5000 turbines and six Senvion 5M turbines located some 45km north of the island of Borkum.

The 60MW project was commissioned in April 2010, when it became Germany’s first offshore wind farm.
