5 Welcome to our Service Booklet 2020/2021!

Despite all the different industrial and energy policies, all scenarios point to a strong, global expansion of renewable energies, and this is particularly true for wind energy. The service and maintenance of wind turbines is a key specialist discipline for the expansion. A study* published in 2019 shows how onshore service markets are currently developing strategically worldwide. According to this study, independent service providers such as Deutsche Windtechnik have established themselves as a fixture in the European service market. At the global scale, more and more operators are weighing their options of service from the turbine manufacturers on the one hand and independent service providers on the other.

The highly dynamic competition, which is being driven by Leading wind energy to success together independent service providers, has led to many improvements, Together with our customers, our goal is to be the world‘s innovations and significant price reductions in the service indus- largest, highest quality and most trustworthy independ- try. In addition, the trend among the major energy suppliers is to ent service provider for wind turbines, both onshore and take charge of parts of the maintenance work themselves. These offshore. We are only capable of this because every one of complex developments lead to a multitude of combinations and our staff puts their best effort and passion for their work into cooperation opportunities for the individual market players.

During the past few decades, we have witnessed a stunning development. Wind energy is the driving force behind the energy turnaround, and it is a key component for a climate-friendly and secure power supply. Turbine expertise NEG Micon Nordex Senvion Gamesa Mitsubishi Deutsche Windtechnik has been very fortunate to be in the right place at the right time. Together with our cus- tomers, who are just as enthusiastic about as we are, we have been able to expand and enhance our system expertise step by step. We now provide a comprehensive range of maintenance services for wind turbines increasingly at the global level. All indicators point to continuing healthy growth.

Rotor blades have to withstand heavier loads than almost any other component of a wind energy system. Depending on the intensity of the load as well as the type and quality of the manufacturing process, defects caused by wear will occur sooner or later. Design and manufacturing defects may also become apparent. Correspondingly, the amount of maintenance that is optimal is different in each case.

Our objective is not only to ensure that Our analyses are based on a stable and growing data pool of systems operate safely and securely, currently over 7,000 wind turbines. This data is complemen- ted by many years of expertise coupled with technical calcula- but also to facilitate continuous improve- tions, careful selection of materials and finally by detailed eval- ment. To strengthen and enhance our in- uation of the prototype tests. These key responsibilities are covered by more than 80 engineers, foremen, technicians and novative skills, technicians and engineers staff with practical experience. An expert team with a focus on in all divisions work daily on the further system software and programming takes care of correspond- ing special tasks. We want our overall range of services to development of our services. convince our clients. All divisions must fit together perfectly to ensure harmonised services.

Improvements/Upgrade system technology Servicing will continue to be a dynamic field of activity. This is reflected by the wide range of creative, innovative upgrades that Deutsche Windtechnik has developed to optimise system operations. In order to redesign existing parts, electrical and mechanical components and tools, we also work with 3D scanners. Each upgrade is the result of an extensive research and development process that is driven by our enthusiasm for servicing and our entrepreneurial agility.

With regard to new designs and further developments, our engineers apply state of the art concepts and work in line with the latest developments. Personal exchange between specialist departments within Deutsche Windtechnik and with research facilities, partners and customers ensures that improvements are developed and applied in the right context. To achieve the desired economic effects, our engineers coordi- nate their work closely with sales and management.

Independence is necessary A comparison of available upgrades from manufacturers and independent service providers shows that independent service in particular is the driving force behind retrofits and improvement of overall servicing. We are convinced that independence from the manufacturer is in fact essential to be able to successfully manage improvement of system opera- tions. The manufacturer of original parts or systems is often trapped within its own responsibility for design shortcomings. Independent companies can focus exclusively on maintenance and look very closely at system performance. They possess key competencies because independent companies have qualified service personnel for a wide range of system generations.

Developing new things together with customers It is important to us to involve our customers as partners in the maintenance processes and the development potential of their own turbines: We maintain a personal dialogue and rely on the direct exchange of information with our customers. Together, we ensure that our engineers develop exactly what you need to sustainably improve system operation.

ONM — On-demand Night-time Marking The adoption of the German Collective Energy Act at the end of 2018 required an amendment to the General Administra- tive Rules for the Identification of Aircraft Obstructions (AVV).

Ensuring that all safety-related equipment functions correctly is a key factor for reliable yields. If malfunctions occur in this area, then this often undermines any service or repair measures because personnel can no longer access the turbine. In addition, considerable potential for danger exists and the operator runs the risk of liability claims. It is therefore necessary to quickly eliminate safety hazards as soon as they are identified.
