INSPECTIONS OPTIMIZATION

OPERATING COSTS REDUCTION

From ice detection and reduction of tonalities to structural health monitoring (SHM) on blades, towers or foundations – in the field of wind energy we offer professional system and services solutions to increase yields, extend the service life and optimize inspections.
We are experts in vibration and signal analysis, provide information on structural damage and the associated service life of your wind turbines, monitor material fatigue and help you to comply with legal requirements e.g. regarding noise emissions.
SERVICEPORTFOLIO

WHAT DO YOU DO WHEN TOWERS SWING?
Strong vibrations accelerate material fatigue and the risk of damage and increase the risk of damage. When wind turbines start to vibrate, individual frequencies in the background noise of the system can become audible – this is referred to as tonality. These tonal components are particularly unpleasant for human perception and often lead to surcharges in noise emission assessments, relusting in turbines being operated only in sound-reduced mode. Vibrations can be significantly reduced using active or passive dampers, helping to avoid additional costs and yield losses.

HOW DO YOU DISTRACT KNOWLEDGE FROM A FLOOD OF DATA?
At "cold-climate" sites, rotor blade icing and ice shedding pose additional risks. Our ice detection system, IDD.Blade, precisely monitors the icing condition and automatically controls both the shutdown and restart of the turbine.
However, we do not only provide tools for analysis. From the planning and conception of an SHM system to the installation and commissioning through to the preparation and visualization of the collected data, you receive all services from a single source.

OFFSHORE WIND ENERGY – HOW DO YOU KEEP EVERYTHING RUNNING SMOOTHLY IN SPITE OF ROUGH WINDS?
Additionally, investment costs for offshore wind turbines are higher, making efficient and trouble-free operation essential for rapid amortization. Structural Health Monitoring (SHM) enables early damage detection and minimizes downtime.
SHM also helps reduce costly, weather-dependent visual inspections (periodic inspections) to the minimum recommended by the Federal Maritime and Hydrographic Agency (BSH). Ideally, inspections are conducted on a risk-based approach, allowing high-risk faults to be prioritized and maintenance activities to be planned proactively.

ONSHORE WIND ENERGY – WHEN DOES WIND MAKE ALL THE RIGHT NOISE?
The available space for onshore wind turbines is limited, leading to the development of increasingly densely populated or difficult-to-access areas. This comes with a wide range of permitting requirements – particularly regarding noise emissions. According to the Federal Immission Control Act (BImSchG), wind turbines exceeding a total height of 50 meters require approval, which includes an immission forecast as well as a noise emission measurement after commissioning.
As an independent measurement institute recognized by the Society for the Promotion of Wind Energy (Fördergesellschaft Windenergie; FGW e.V.), we conduct these measurements to ensure compliance with approval requirements and to document adherence to the specified sound power levels.
