Blade
Tower Services

Runs! – Reliable service with perspective

Rotor blades are exposed to rain, frost and lightning strikes or even sea air during their entire operating life—they do need care.

Certified quality and 25 years of experience as well as an extensive damage database (over 15 years of damage collection, 3,000 WTGs, over 100 blade types, detailed damage descriptions) make us the most reliable partner for inspection, maintenance, optimization, repair and service of your rotor blades.

We also offer customized monitoring packages for preventive and predictive maintenance of rotor blades, as well as safety checks. All these measures not only extend the service life, but also noticeably increase the yields of your wind turbine. We never stand still: Together with research, partners and our customers, we are constantly developing our services further.

In the event of damage, our team is on site immediately—in Germany and throughout Europe, with offices in Spain, Greece and in the USA. And with certified partners soon in France, Sweden, South America and India.

Our perfectly trained teams work under the highest HSE standards. They use innovative tools and materials. Database-driven and certified processes guarantee efficient and sustainable blade service—from damage assessment to repair.

For preventive maintenance of your rotor blades, we use our working platform technology or rope access technology. We offer full service for the maintenance of all available rotor blade types. We are also the ideal partner for upgrades, vortex generators, serrations or aerodynamic optimization of your wind turbine. Your goal is our goal: reaching the calculated yields of your wind turbines for their whole life cycles.

Our inspection services

Our complete package for the inspection of rotor blades combines data collection through internal, external and standardized checklists with processing and evaluation in a detailed report—including post-processing for preventive maintenance. We combine the resulting expert analysis of all damage with suggestions for repair and maintenance measures.

Our service portfolio comprises:

Inspection rotor blades
Torque control of the screws
Inspection rotor blade surface on demand
Blade interior inspections
Periodic inspections of rotor blades
Rotor blade expert opinion at the end of the warranty / in case of lifetime extension
Inspection of the Lightning protection system

The inspection is carried out by means of:

Our repair maintenance services

We offer reliable, standardized or manufacturer-specified solutions for the repair of rotor blades using rope access technology, cherry pickers or rotor blade access equipment. On-site repairs have the great advantage of eliminating transport logistics while minimizing downtime.

Service Innovations

No matter whether you need help with completing a major project or just minor repairs—our ‘Service Intelligence’ project allows us to develop integrated service concepts together with our partners for making our customers‘ existing wind turbines more productive in the long run.

retroX: digital transparency for existing plants

fos4X offers a stand-alone retrofit solution called retroX for the digitalization and efficiency enhancement of existing systems. Individual turbines as well as entire parks are integrated into a cloud-based IoT environment. The collection and extrapolation of load data provides reliable information on the remaining useful life of the system.

3M Vortex Generator

The installation of 3M Vortex Generators on the blades increases the turbine performance.

3M Wind Protection Tape

With the application oft he 3M Wind Protection tape leading edge erosion can be significantly reduced and even be eliminated.

Bladena D-String And D-Stiffener

The blade retrofit with Bladena D-String and D-Stiffener protects rotor blades from structural damages from the max chord to mid span region. This leads to longer live time and more performance.
