“We Predict How Long a Wind Turbine Will Last”. The first generation of wind turbines has been operating for quite some time. In the coming years, we will need to replace tens of thousands of them. But could some still remain operational? With the help of innovation funding, Sensing360 has developed a new technology that can accurately predict the remaining lifespan of wind turbines — a breakthrough that can result in major cost savings.
Over the next few years, an estimated 70,000 wind turbines will need to be replaced in Europe alone. Thanks to Sensing360’s technology, owners can decide to keep some turbines in operation, which represents a significant cost reduction. It also helps reduce the risk of unexpected turbine failures.
Wind turbines contain gearboxes that make it possible to efficiently generate energy from the rotating blades. Bearings help minimize energy loss. Since 2018, Sensing360 has been developing a monitoring system for this purpose.
“We wrap fiber optic sensors around the gearbox to measure forces, rotational speed, temperature, and deformation,” says Eric van Genuchten, co-founder of the company.
The monitoring system provides critical insights.
“This allows for highly efficient maintenance scheduling,” Van Genuchten explains. “Moreover, based on the measured loads, we can predict how much longer a wind turbine will last.”
This is why Sensing360 was nominated for the Offshore Wind Innovators Awards. “That nomination was a real honor for us,” says Van Genuchten.
The monitoring system can be applied to rotating components — not only the gearbox, but also the generator bearings. That’s exactly what Sensing360 is doing in partnership with Somni Solutions.
“Together, we’re developing a solution to monitor all major systems within a wind turbine,” Van Genuchten explains. “Including software that gives turbine operators full insight into system health and performance.”
To develop this new technology, Sensing360 and Somni Solutions are supported by the Energy & Climate Research and Development (EKOO) grant.
“It enables us to conduct field tests on existing onshore wind turbines in the UK and at Wageningen University,” says Van Genuchten. “We want to validate whether the sensors function well and whether the system provides reliable predictions.”
Van Genuchten is grateful for the grant support.
“As a small company, you have limited resources to push your innovation forward. With funding and smart, cost-effective development strategies, we can take the necessary next steps.”
