Getting almost every spare part and accessory for wind turbines from a single source to the customer - this is the business model WINDSOURCING.COM launched in 2013. Within three years the Hamburg-based company has developed to become the largest online distribution platform for the wind sector. PES Wind Magazine reports how the company was created and what concept stands behind it. “When it comes to failures in the operation of wind turbines, the time factor is decisive for operators and owners,” Stefan Weber, Managing Director and Founder of WINDSOURCING.COM, tells us. “One substantial factor to help reducing the downtimes of wind turbines is a good availability of spare parts and repair material as well as a well organised and expedited transport from the warehouse to the destination.” This is the point WINDSOURCING.COM comes into play. The distribution company is often the final lifeline for a service engineer or a wind farm operator. WIND-SOURCING.COM provides almost every part required to get a failed wind turbine system going again. Stefan Weber and Seher Kaygusuz set up their distribution company WINDSOURCING.COM in 2013, entered the profit zone in 2015 and are now making a name for themselves in the wind energy sector.

Words: Philip Rood The marine renewables market is ever growing and SEA, a part of Cohort plc, has expanded its engineering capability to provide a variety of support services to the wave and tidal energy sectors. Cohort plc, business SEA, has showcased its credentials, in the growing wave and tidal energy support sector, by installing a 13.2kV cable connection to support the Oceantec wave energy device located at the Biscay Marine Energy Park (BiMEP) test site in Northern Spain. BiMEP tests prototype devices for generating wave energy, in advance of commercial production, to ensure economic and technological readiness and to ensure they are reliable and safe for commercial deployment. Once the devices have been verified, they can be considered ready for mass production and operational use. A team of engineers and technicians from SEA, subsea engineering division, terminated the device cable connection onshore and travelled offshore to connect the two halves at the wave site. The device is now fully operational and generating wave power back to shore. The BiMEP connections are a new variant of the nine 33kV connections first installed by SEA in 2009 at the Orkney-based European Marine Energy Centre (EMEC) test centre for marine renewable energy. The connections supplied by SEA

Joachim Rother, Technical Director, novatic COATINGS Group The novatic® COATINGS Group has an extensive portfolio of high quality coating materials, for industrial corrosion protection, for use in various industries. There is a wide range of corrosion protection systems and applications available ranging from easy to use, for the protection of interior steel constructions, without additional demands, to high corrosion stress in maritime domains (C5M-high), as well as the protection of steel constructions within an industrial atmosphere (C5I-high), also with permanent exposure to moisture and for the chemical industry with its additional demands. Proven coating systems for the protection of the materials e.g. steel, spray- and hot galvanised steel, stainless steel, concrete and the like are available. This is why novatic® has been very successful over the past 20 years, in the wind energy sector and has numerous references. In the middle of the 90s the first wind turbine steel towers (WTGS) were coated with a novatic® corrosion protection system. The importance of this market was already recognised at this time, so product development was purposefully encouraged. A team, composed of chemists and application technologists, successfully worked on applications on towers, drive engineering, gondolas, hubs and rotor blades. They developed a focus

DONG Energy awarded DEME’s subsidiary Tideway cable installation contract for the Hornsea Project One offshore wind farm. PES investigates to find out why and introduces readers to the ‘Living Stone’. Early June this year, Tideway BV, Breda, the Netherlands, a subsidiary of the Belgian dredging, environmental and marine engineering group DEME, was awarded a cable installation contract (Transport and Installation) by DONG Energy for the world’s largest offshore wind farm, Hornsea Project One. Tideway will deploy DEME’s newest, multipurpose vessel (MPV), ‘Living Stone’ for this project. This Dynamic Positioning 3 (DP3) vessel is the most advanced subsea cable installation vessel in the world. It is currently being built by the Spanish shipyard LaNaval near Bilbao, Spain. The ‘Living Stone’ will have two turntables below deck each with a capacity of 5,000t making a total capacity of 10,000t. There is also the possibility of a third carrousel above deck with an additional load capacity of 2,000t. Delivery of the state-of-the-art ‘Living Stone’, which is equipped with dual fuel engines, is scheduled for April 2017. LNG will be the primary fuel. This means the ‘Living Stone’ will be amongst the cleanest installation vessels in the world, having a Green Passport and the Clean Design Notation, which

Offshore terminals are the most important interfaces during the construction of wind farms off the coasts of the North and Baltic Seas. Many wind farms have been created in recent years and more are already in the planning stages. The Hamburg-based company Buss Port Logistics (Buss) recognised the opportunities early on, and with their own Orange Blue Terminal (OBT) in the Dutch port of Eemshaven, they developed the “Offshore” sector. Martin Schulz, Head of Offshore Logistics at Buss, offers PES a glimpse behind the scenes: from the initial planning of a terminal to the completed offshore project. From sandy desert to a heavy cargo terminal The Eemshaven offshore terminal was already an important hub for many projects in the North Sea. However, in order to bring ashore the massive components, to put them in intermediate storage, to perform the pre-installation and to ship them back out, extensive construction measures were required at the terminal, situated on the southwestern bank of the Ems estuary. “When Buss came to visit the future terminal in Eemshaven for the first time, it looked more like a sandy desert, without even a quay wall in place,” explains Schulz, adding: “The management team was quite optimistic however. This way, Buss

Words: Dr. Wolfram Palitzsch, Loser Chemie GmbH Loser Chemie is developing high quality, cutting edge recycling technology especially for the photovoltaic industry. The recycling of this waste is important from a political, economic and environmental perspective. Loser Chemie GmbH (LC) was a chemical company whose main business was in water chemistry. Recently Mr. Loser restructured his company. He founded a holding company and sold the aluminium and barium chemistry sections. In order to build and run a photovoltaic recycling turnkey system he bought a plant engineering company – TESOMA GmbH. Loser believes that you can only expect a first-class solution from a specialist. Thus Tesoma has established a reputation for providing precisely that, especially in the handling of flat glass. The company ranks as an international market leader when it comes to drying and fixing. Tesoma develops and manufactures their dryer systems in exclusive cooperation with JRT Photovoltaics. The highest precision and optimised processes allow mean minimal breakage when producing solar wafers. Partnering with qualified market leaders gives the competitive edge along with the maximum possible potential for photovoltaic modules. This venture has brought the Loser group in to the photovoltaic industry. LC is aware that in the future natural resources such as water or

100 years ago, the world was introduced to the first generation of pyranometers. These thermal hemispherical viewing devices measured the irradiance of the sun on a horizontal surface. Since that first generation, small design changes have been made to improve this state of the art technology. However, all of those changes have been incremental; small changes, yielding small improvements. An entirely new design was needed to make major improvements. EKO Instruments recently made some very big improvements to the pyranometer design. The new MS-80 Secondary Standard (highest class sensor) pyranometer performs at a level never seen before. Using unique detector technology and sensor architecture EKO has pushed the performance in a way no one could have predicted. This single dome sensor is less expensive to produce, when these savings are transferred to the customer, combined with the enhanced performance, the result is the best performing sensor in its class with a low cost of ownership. Why a new detector and with new architecture? While there are silicon photodiode radiometers that respond very quickly to changes in irradiance, the uncertainty in the measurements is rather high. Meteorologists, as well as the photovoltaic (PV) industry, needed a sensor that had a time constant more similar

Quality is ever important in our industry and now Breyer have come up with a high quality, high speed extrusion process which has already been tested by TÜV Rheinland Germany…. BREYER’s extrusion system “CellProtect” allows the production of low shrinkage EVA encapsulation film at high production speed. Most importantly, there is no interlayer film and there is no energy consuming anealing process, which means the production is economic in terms of both cost and energy. Furthermore, Polyolefin encapsulants can be processed using the same method. Encapsulation film produced on regular extrusion lines has a natural shrinkage which affects not only the laminating process but can result in destroyed wafers and therefore creating waste and thus increased production costs. A high quality and low-shrinkage film allows a smooth and fast laminating process. The more shrinkage a film has the more carefully the warm up procedure must be controlled and could increase the laminating time. Since the regular extrusion systems, using calendars or cast rolls, are limited to a certain speed/output, BREYER has developed a profitable system for the production of EVA film and other gluey materials. For the first time, using BEYER CellProtect, it’s possible to extrude EVA or Polyolefine films film at high speed by
