fos4X Watches Over Veja Mate Blades

Operations & Maintenance

Veja Mate Offshore Project GmbH has selected fos4X GmbH to provide a rotor blade condition monitoring system on the 402MW Veja Mate wind farm in the German North Sea.

The fos4X “retroX” system, consisting of a sensor platform and intelligent software, was installed on strategically selected 10% of the wind farm’s turbines.

The system enables structural condition monitoring of the rotor blades, recording of loads during turbine life time as well as the detection of yaw and pitch misalignment, fos4X said.


A further aspect of the joint project carried out by fos4X is the monitoring, consolidation, and orchestration of the entire turbine and subsystem data. The provision of the data to VejaMate as well as further analyses are realized on the fos4X IoT data platform. This provides the operator with essential information for determining the remaining lifetime and continued operation scenarios.

“With fos4X we have found a competent partner for our rotor blade condition monitoring as well as for an extended data infrastructure and analyses,” Stefan Klett, Managing Director, Veja Mate Offshore Project GmbH.

Located some 95 kilometres northwest of the island of Borkum, Veja Mate comprises 67 Siemens SWT-6.0-154 turbines which were put into operation in May 2017.
