Warranted quality and 25 years of experience make WKA the most reliable partner for all repairs and servicing of your rotor blades.

We don’t just specialize in rotor blades, but also in the replacement of major components of a wide range of different systems. These components include rotor hubs, drivetrains, gear boxes and generators. Thanks to our ROTALIGN Ultra iS – a new generation high-end laser optical alignment system manufactured by Prüftechnik – we are able to precision align the drivetrain, from the gearbox to the generator, to within two hundredths of a millimetre.

In the event of damage, our team will be on site right away, anytime, anywhere in Germany, all over Europe with subsidiaries in Spain, Portugal and Serbia. In the US. With certified partners soon in France, Sweden, South America and India.

Our perfectly trained teams work according to the highest HSE-standards. They use innovative tools and materials, and their database-driven, warranted processes guarantee efficient and sustainable blade service, from damage assessment to repairs.

To enable preventive servicing of your rotor blades we use our platform technology or rope-access technology. We offer full service for the maintenance of all available types of rotor blades.

But also for upgrades like Pitch optimization, Vortex Generators or aerodynamic optimization of your wind turbines we are the ideal partners. We keep developing our services in close co-operation with research, partners and our customers.

We offer reliable service with an eye to the future. To guarantee the calculated profits of your wind power stations, on- and offshore.

Future challenges for wind farm operators and their service partners

A guest commentary by Julian Scheerhorn, Operations Management, Energiekontor

Julian Scheerhorn

Wind power will become increasingly important in the future. At Energiekontor, we have the self-imposed target of achieving one hundred percent renewable energy.

Nevertheless, we face new challenges as a result of the changing conditions. With the new wind farms, the tendering procedures have led to a significant drop in prices. The resulting cost pressure equally affects everyone involved. The problem for existing parks is that after 20 years, the EEG tariff has been eliminated, thereby reducing the competitiveness of the systems. This means that all the companies involved need to be more efficient and cost-effective.

Therefore, it is important to optimize and develop the wind farms. This includes compensating for tower passages through pitch, or if necessary, undertaking adjustments to the entire wind farm to keep lagging effects under control. Now that many of the existing farms are at the end of their operative service lives and have to cope with the market values for electricity on the stock market, appropriate optimization measures are very helpful to ensure their profitability.

In optimizing our wind farm in Thüle with our service partner WKA, we rely on vortex generators, which ensure the facility is quieter, more durable and more profitable in the upper partial-load range.

The perfect service partner for wind farm operators is efficient, innovative, customer-friendly, economical, always ready for operation and ensures rapid fault clearance at the worksite.

WKA is not only broadly based, but is forward-looking, which is a clear advantage for us. In addition to their core business of blade inspection and blade repair, WKA also offers innovative optimizations for wind power stations.

WKA 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.

Five Examples

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

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

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.

The PolyTech ELLE Softshell protects the leading edge from erosion.

With support of Gram & Juhl CMS Solutions for monitoring of wind turbines, customers can even better protect their invests and conduct the maintenance of the turbines while optimizing the yield.

The engineering consultancy RECASE Regenerative Energien GmbH provides comprehensive experience in operation and analysis of wind turbines. Based on operating data, root causes can be identified and measures can be defined.

QHSE

The health and safety of our employees is extremely important to us. It constitutes a primary corporate objective, which results in key managerial responsibilities. We seek to promote a sense of responsibility among all employees, to be mindful of their conduct at the workplace and to act in a safe manner, and give consideration to ergonomics and occupational health and safety from the planning to monitoring stages in all operating processes.

We are continuously working towards developing preventive measures to prevent accidents and work-related illnesses, with the aim of minimising risk for our employees and third parties, and improving occupational heath and safety.

Alongside our customers, our motivated, professional and entrepreneurial employees play the most important role in our success. We reward courage and commitment. We provide relevant information and training and promote personal and professional development in line with our corporate goals.

Every employee is responsible for the quality of their work within each of their working processes and as such we ensure that our services fulfil and maintain the high standard of quality expected. Acting with foresight takes precedence over follow-up and we guarantee this through the application of effective practices and procedures. Any defects in products and processes will be communicated openly, analysed and effective measures will be taken to rectify the causes of the problem.

Through ongoing training of our employees and a high level of innovation, we are able to meet the ever-increasing demands of our customers, thereby also ensuring our quality standards in the future.

Protecting the environment and steadily improving energy efficiency constitute our key corporate objectives. We are committed to continuously expanding company environmental protection, e.g. through the use of top-quality technology where it is economically feasible.

Our management system ensures that tasks are implemented in all functions and at all levels.
