An offshore platform in the North Sea that is the first of its type to serve a power generating wind farm is home to 50 Rotork IQTPro intelligent electric valve actuators.

The Borwin Alpha platform is the first offshore installation designed to convert AC power into high voltage direct current (HVDC) for onward transmission. Built and designed by the Heerema Fabrication Group on behalf of ABB, the facility can transfer a power of 400 MW at a bipolar voltage of 150 kV. The converted current is carried by a 200 km cable for onshore connection to the European power grid.

The BARD Offshore 1 wind farm, served by the Borwin Alpha platform, is situated 100 km northwest of the German island of Borkum. Eighty wind turbines will be installed when the farm is completed in 2012. The 200 km cable connection to the mainland is the longest in the world for an offshore wind farm, as well as the first to utilise HVDC transmission.

The majority of the Rotork IQTPro actuators are controlling the operation of butterfly valves in applications on the cooling system for the power conversion plant and the fuel systems for emergency generators. Some of the valves are installed within the platform superstructure whilst others are outside and exposed to the harsh North Sea environment.
