What are the characteristics of the Radial Gear Chamfering process? Defined and reproducible chamfering at the front edges of the teeth increases the economic efficiency of production. At the same time, the quality of the components is improved In the field of metal-cutting gearing, increasingly complex and demanding component geometries require burr-free edges and precise surfaces in production. To prepare for these requirements, Framo Morat GmbH & Co. KG has expanded its competencies in gear cutting technology and added a RGC 350 deburring machine from TEC for GEARS to its machine pool. The Radial Gear Chamfering process allows defined and reproducible chamfers to be produced on the tooth front edges. This not only has a positive effect on the quality and functionality of the components, but is also decisive for the cost-effectiveness of parts production. In GearValley, nestled in Germany's Upper Black Forest region, the traditional company Framo Morat has been producing precise gear components for a wide variety of applications for over 100 years. The range of parts includes spur gears, pinion and rotor shafts, ring gears, chain and pump gears as well as gear segments and special profiles. In a production area of 18,000 m² at the headquarters in Eisenbach,

Siemens publishes advice for businesses on steps to decarbonise Decarbonisation is a clear global target and there is a growing urgency for businesses to act. If they don’t, they risk exposing themselves to potential risks from policy-driven increased operating costs, increased energy costs or increased compliance costs. In addition, decarbonisation is not just an objective imposed by policies such as the Paris Agreement: with the right approach, it also creates tangible business opportunities that go beyond long-term financial savings. These include increased brand reputation, customer preference over competitors and attractiveness to investors. Industry leaders have paved the way, with Google having been carbon-neutral since 2007 and Microsoft since 2012. Now it’s time for other businesses to follow suit. Technical advancements such as digital solutions and decentralised energy systems have made decarbonisation more feasible. To help businesses create their individual decarbonisation strategies, Siemens has published a new whitepaper suggesting a range of specific steps towards carbon neutrality. These are grouped into three different areas: actions on the management side, actions on the energy demand side and actions on the energy supply side. Actions on the management side These steps will typically be overarching and strategic. Assign responsibility to an energy specialist internally, to ensure a

A wind Lidar is quite simply a remarkable piece of technology recently described by Avangrid as having ‘advanced the wind industry globally’. Generic Lidar benefits are summarised by Renewable Energy Systems (RES) as being ‘safer, cheaper, better, faster’ than traditional meteorological masts. An invisible, eye-safe beam of light interrogates the sky above at user defined heights and determines the characteristics of the wind in order to advise and improve wind and meteorological industry understanding around the world, onshore and offshore, on fixed and floating structures. Continuous Wave (CW) Lidars are able to achieve something unique in addition; this is due to their on-board ruggedized focussing system that allows for the following features: 1. All the laser power is focussed at each specific measurement distance ensuring very high sensitivity which in turn allows wind measurements to be rapidly integrated over short periods of times on moving platforms e.g. floating Lidar applications, or when the wind flow is changing rapidly, such as in complex flow, and equally over large areas when scanning the larger wind field, for wind turbine performance measurements and control. 2. In all applications the focussing of the laser also ensures maximum availability that is not subject to the range being interrogated i.e.

With the launch of the SHIFT platform four years ago, ZF Wind Power changed the wind gearbox market in terms of flexibility, product lifetime and competition. Thanks to a design based on standardized building blocks, the platform offers high flexibility in gearbox development for next-generation turbine concepts. Currently, the platform has been extended with two new members: SHIFT 3k to the lower end of the torque scale and SHIFT 7k at the high end. Together with the 4k and 6k variants, the SHIFT platform contributes to the lowest levelized cost of energy in all wind areas. Competitive design raising the torque density bar above 200Nm/kg During its 40 years of activity in the wind market, ZF Wind Power has shipped 150 GW of gearboxes worldwide, of which 75% of today’s shipments are based on the modular platform design. With a torque range of 2000-8000 kNm, all onshore and offshore wind sites can be covered. Where the SHIFT 7k variant with a maximal torque up to 8000kNm addresses the high power and high output onshore segments as well as dedicated offshore markets, the SHIFT 3k variant was added to the product family specifically to cover the demand in view of low to very

Online trade is the big winner of the Corona crisis. This also applies to the spare parts and repair market for wind turbines. A Hamburg company, a pioneer in this niche in 2013, is now gaining momentum despite, or because of Corona. Stefan Weber, Founder and Managing Director of Windsourcing.com GmbH, shares his thoughts with PES on how the foundation of a digital trading company came about and how much more importance digitization has gained among the broad masses in the context of the Corona crisis. I am an Amazon fan. Please do not misunderstand me. It is completely unacceptable not to pay sales tax from Asian suppliers in Germany and to pay little if any company tax at all. No, I am a fan of focusing on the customers and their benefits: the punctual and fast delivery and using the distribution channel Internet. This enthusiasm has driven me already in 2013 when I founded Windsourcing.com. It was clear to me that digitalization does not stop at renewable energies and here the industry and the entire energy industry can learn a lot from Amazon and Co. Prior to the foundation of the company, I had already been working for many years

The anti-icing blade heating technology is the enabler for windfarm power production in extreme icy conditions in Quebec, Canada. The efficient use of heat keeps the turbines operating up in the mountains, in the most demanding, freezing conditions, such as Lac Alfred wind farm. It consists of 150 wind turbines, with total capacity of 300MW and is located up in the mountains of Gaspe peninsula, Quebec. The wind farm is heavily influenced by the proximity of the Atlantic Ocean. It has vast wind resources, but the combination of moisture rising out of the sea that stays open the whole wintertime, high altitudes and the cold weather means the environment is prone to icing conditions. The winter is long and usually starts in October and ends in April. The turbines tend to stop easily if any ice is detected by their sensors. Many of the turbines here suffer heavy icing, which leads to long periods of complete standstill. This leads to losses of about 15% of the annual energy production, AEP. It was obvious that something needed to be done in order to save the investment. ‘Until the summer of 2016 we had only used our blade heating technology on new turbines,’

The 2nd offshore wind boom is upon us and this time it is going global. During 2021 project installation will be underway in UK, Denmark, Germany, Netherlands, Belgium, France, Norway, Spain, Portugal along with US, Vietnam, Taiwan and China. By 2025 many more countries will join this rush to install the cheapest form of largescale renewable power available. The last 10 years of this sector has been about major efficiency gains. This has been brought about by giant leaps in generating capacity, huge economies of scale and general efficiency throughout the supply chain. Turbines can now be erected and commence operation within 24hrs or less. Installed redundancy has reduced the need for regular intervention. Key failure points have been removed. All of these and many more have helped offshore wind find its place as the keystone within the generation mix for decades to come. With this in mind, and looking to further enhance the efficiency of this green industry, one must note that the means of access to these offshore farms heavily relies upon a marine logistics fleet which currently has a hefty carbon footprint. Whether it be the installation vessels, survey boats, cable layers, jack-ups, SOVs, CTVs or helicopters, the amount of

Following on from our interview with Wim Keen in the last edition, PES had some questions for Maik Rienecker, founder of Steel Inspect and father of the unique Q7 concept for optimal quality management of offshore windfarm EPCI (Engineering, Procurement, Construction, Installation) projects. He was happy to explain the Q7 concept in more detail and share the benefits this brings to offshore wind farm construction projects. PES: Hi Maik, welcome back to PES Wind, for the second part of the interview, following on from the last issue. For the benefit of our new readers, would you like to begin by telling us something about the history of Steel Inspect? Maik Rienecker: Steel Inspect and especially its predecessor Rienecker PM was founded in 2006. At this time, I had already gained wide experience over the years from 1990, in purchasing and quality management for manufacturing, including site construction and commissioning for worldwide EPCI power plant projects. Consequentially I capitalized on this experience I gathered from various kinds of projects worldwide and founded the company. From 2016 we consistently pursued the growth path, as a quality service provider for inspection and monitoring. The establishment of Steel Inspect allowed us to pool the experience
