Senvion is a global company with a broad focus. This is also reflected in its after-sales services. Offering services on a global basis means being optimally placed to respond to different requirements with a wide range of products. But what do after-sales services at Senvion involve exactly?
“While studying for my degree I attempted to build a wind turbine with some fellow students. It never worked, though,” explains Jan Balbach, laughing. Today, as Team Lead Service Products at Senvion, he deals with services offered to customers who already have a wind turbine. “So that their turbines run smoothly – unlike my uni project,” he adds. There is particular demand for software upgrades that enable wind turbines to react more rapidly to weather conditions and thus to run more efficiently, or for aerodynamic optimization of rotor blades using serration indents on the trailing edge to reduce stalls, thereby making the turbine significantly quieter.
Finding the right solution for every climate
In northern Canada and northern Europe it can get very cold in winter – there is the risk of ice settling on the rotor blades. If pieces of ice become loose while the turbine rotates they could be thrown long distances and cause damage. In order to avert this risk the turbines are shut down as a preventative measure. However, the longer the time a turbine’s period of inactivity exceeds the period that is technically necessary, the higher the loss of earnings for the customer.
The ice detection system has been so well received that it has now become standard for new wind turbines in Canada and central and northern Europe.
For this reason, Senvion has developed a rotor blade ice detection system. “Sensors can reliably detect whether ice has settled on the blades. If it has, the turbine is shut down automatically. As soon as the ice has melted off the blades the turbine starts up again,” continues Balbach, explaining the value added by this after-sales product. Using the system eliminates the need for extensive visual inspections on site. The result is reduced downtime and lower staff costs for the customer. “The ice detection system has been so well received that it has now become standard for new wind turbines in Canada and central and northern Europe,” adds Balbach proudly.
Efficient turbines thanks to the right maintenance concept
“The customer doesn’t just buy the turbine from us; they may also expect maintenance, repair, performance monitoring and availability throughout its entire service life. We aim to meet or even exceed these expectations through our service,” says Rostislav Beslimov, Head of Service Sales International, in summary of his team’s ambitions.

Beslimov is fascinated by wind energy and pursues the objective of offering Senvion customers as individual a service package as possible. Flexibility is the greatest benefit offered by the Senvion Service Sales team: “With customers who have their own service departments we tend to provide basic technical support; with others we provide a complete service.”
