Hans-Peter Zimmer, CEO, blade care GmbH and trainer at the blade care Academy, had so much to share last issue that PES felt a follow up interview was necessary. We wanted to find out in more detail about clients’ motivation and some of the specific know-how the Academy offers. Research is also an integral part of improving the services and training offered. PES: Thanks for coming to talk with us again. In our last interview we learned a lot about blade care’s service on rotor blades and the Academy training programmes. We thought it would be interesting to have more details about what types of training the Academy offers and to have more information on your new reporting and management software. To begin with would you like to tell us which the most popular topics in the seminars for administrators? Hans-Peter Zimmer: Clients feel much more confident once they know about the blade structure. The administrators and decision makers need to know the importance of visible and invisible damage. An example is the need to understand the effect of lightning strikes. Some clients are not aware of the fact that plasma arcs can be generated inside the blades. Internal plasma arcs can cause

ZF is a leading pioneer in cost-efficient wind turbines. The reduction of Levelized Cost of Energy (LCoE) is their principal aim. The SHIFT platform concept means it’s now possible to optimize gearboxes for specific-site loads. PES wanted to know more. LCoE of wind energy happens with big evolutions in wind technology. Big is important. There are a couple of ways to produce more power from the wind in a given area. The first is with larger rotors and blades to cover a wider area. That increases the capacity of the turbine, i.e., its total potential production. The second is to situate the blades higher, where the wind blows more steadily. That increases the turbine’s ‘capacity factor,’ i.e., the amount of power it actually produces relative to its total potential. The more variable a source is, the more backup is needed to firm it up and make it reliable. By making wind less variable and more reliable, higher capacity factors reduce backup costs. With increasing capacity factors wind can spread its energy out over a longer period, easing wholesale price pressure during low demand. By extending its hours of operation, a high-capacity-factor turbine is more likely to be producing during demand peaks, when power is

250,000 items, and now over 300 delivery partners – in the last two years the Hamburg-based wind energy products distributor WINDSOURCING.COM keeps on growing. These are exciting times for this go ahead company. This spring, for example, the Finnish abrasives manufacturer Mirka and Kömmerling Chemische Fabrik GmbH joined as partners. Managing Director Stefan Weber explains the success of the company is due to the continuously growing product portfolio and simultaneously its proximity to customers, suppliers, manufacturers and products. Once again in September WINDSOURCING.COM will be at the leading trade fair, WindEnergy 2018, in Hamburg with a selection of its products and services. ‘We are not an anonymous internet platform,’ Stefan Weber explains the company’s success: ‘Our customers can contact us by phone or in person in several languages. Our products and services come with concrete faces and names that they can trust. The personal accessibility and relationship are very important, both for our customers and for us as a company.’ This is one of the reasons why participation in trade fairs, such as the WindEnergy in Hamburg, where the distributor has had its own booth since the first show in 2014, are important for the team: ‘People also want to touch products, and may have

Danny Ellis, CEO and co-founder of SkySpecs, dropped in to PES to give us the latest on the different maintenance strategies and why he thinks his company has the best proposition. PES: Welcome back to PES Wind magazine. It’s great to talk with you again. For the benefit of our new readers would you like to begin by explaining a little about the background of SkySpecs and the importance of the wind industry to you? Danny Ellis: SkySpecs is focused on wind turbine blade diagnostics and maintenance, providing robotic technology that completely automates the visual inspection, analysis, and prescription maintenance of blades with drones. Our inspections take 15 minutes or less per wind turbine, and we inspect all four sides of all three blades in a single flight without any manipulation of the wind turbine. We do not require any prior information about the wind turbine because the drone is programmed to identify and learn about the turbine when it takes off. This streamlined approach allows us to conduct around 25 turbine inspections, with a single drone, in one day. SkySpecs recently introduced Horizon – an analytics, reporting, and management software platform for the wind energy industry. Horizon allows customers to review, prioritize and

When it comes to occupational safety, emergency rescue plans are a critical factor that should not be overlooked. Every company is obliged to create these as part of a risk assessment — including the wind energy industry, which employs tens of thousands of people. For example, if an accident occurs during maintenance or servicing of a wind turbine, basic rescue concepts may not be sufficient. In such cases, personnel with specialist training in rescuing accident victims may be required — individuals who have completed advanced rescue training of the kind that manufacturers of fall protection equipment, such as SKYLOTEC provide. The German company develops and manufactures complete solutions ranging from harnesses to descend devices and rescue stretchers, and also offers a comprehensive training programme worldwide. Maintenance technicians in the wind energy industry typically work several hundred metres above the ground — and must therefore protect themselves against the dangers of a fall from height. They are required to wear fall protection equipment by law, and for good reason. However, occupational safety is not solely the responsibility of the employees themselves — their companies must also fulfil certain obligations, for example by formulating a carefully planned response in the event of an

Offshore wind turbines are the giants of wind power and their construction is an impressive spectacle. Extremely heavy, massive components are moved on the water by even more powerful equipment. Over the past decade, the German company Schmidbauer GmbH & Co. KG has established itself as a logistics partner for the offshore industry. This company has not only continuously expanded its fleet of crane vehicles to meet the needs of the industry, but also invested in the service know-how of its personnel. New 6-axle Scheuerle SPMTs were purchased last year alone. So the crane and heavy-load expert is therefore in action at numerous European feeder ports and ports involved in the construction of offshore wind farms. Heavy load logistics for the Merkur offshore wind farm One of the current projects: the transhipment of transition pieces (TPs) for the Merkur offshore wind farm, at the Orange Blue Terminal in the Dutch port of Eemshaven. 66 ‘Haliade 150’ GE-type wind turbines, which should achieve a standard capacity of approx. 1750Gwh per year, are currently being constructed in the North Sea, about 45 kilometres north of the island of Borkum. The work for the construction of this wind farm started at the beginning of 2017 and it is expected
