German company Fos4X is carrying out a condition monitoring campaign at the 402MW Veja Mate offshore wind farm in the German North Sea.
The deal also includes early and data-driven optimisation of the maintenance strategy and estimation of the turbine life time extension through specific load measurement.
Fos4X has deployed its RetroX system, which consists of a sensor platform and intelligent software, on 10% of the project’s 67 Siemens Gamesa 6.0-154 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,” the company said.
Fos4X is also monitoring, consolidating and orchestrating the entire turbine and subsystem data through its IoT data platform.
“This provides the operator with essential information for determining remaining life time and continued operation scenarios,” it said.
Veja Mate Offshore Project managing director Stefan Klett said: “With fos4X we have found a competent partner for our rotor blade condition monitoring as well as for an extended data infrastructure and analyses.”
