Detect ice events acoustically

Acoustic ice detection is an add-on to our on-tower sensor system for detecting rotor blade damage, which is installed directly on the tower.

Based on acoustic changes, our system detects whether there is ice accumulation on the rotor blades or not – you will be alerted when light icing has started and receive 30-minute reports and notifications of persistent icing events.

Ice on turbine blades is a significant issue in some colder climates, causing damage and potentially becoming a safety hazard. This can lead to turbines being shut down for long periods and subject to dangerous ice load, resulting in revenue and energy shortages. We have developed a less costly and more effective software upgrade to our system, that continuously monitors blades to detect icing along with any change or damage, providing additional blade icing detection time compared to traditional methods.

These are the benefits of our on-tower ice detection solution

Improved analysis

The on-tower ice detection system uses an improved acoustic analysis to monitor the sound of wind turbine blades and detect the presence of ice on them, notifying operators through the cloud.

Improve efficiency

Early ice detection allows operators to minimize damage, improve efficiency, safety and increase energy production.

Optimised revenue

The continuous monitoring reduces costs on maintenance and unnecessary inspections, optimising wind turbines operation and revenue.

Need more information about the icing condition of your turbine?

Our on-blade system measures directly at the outer rotor blade surface and provides you with comprehensive information on ice thickness and surface temperature. In addition, the system also offers you the option of fully automatic operation under icing conditions. You can find more information here.
