PES investigates how the Altura Zenith unmanned aerial system performs at sea in high winds, as Aerialtronics announces separate radical technical developments with NVIDIA and the IBM Watson Internet of Things Platform on the cloud. Overcoming gales to inspect wind turbines in the Baltic Sea is one reason why Euro Drone Inspections use the Altura Zenith unmanned aerial system from Aerialtronics. Another is the Dutch UAS manufacturer’s rapid integration of ground-breaking technology. Euro Drone Inspections were an early adopter when it came to choosing the Zenith, which has given them an edge over their competitors. Using the Zenith UAS has proved to be a very effective method of inspecting wind turbines, especially where there are safety issues concerning personnel. Rik Bijl, Chief Executive Officer of Euro Drone Inspections, says they use specialised software and geometrically calibrated cameras to take measurements and collect images for surveys on wind turbines. The advantage is that if any cracks are identified, they can revisit the site to see what changes have occurred. “We can capture data with UAVs that we were not able to capture before,” he says.

PES hears from the Belgian company, ADEDE, about the challenges they face during the search for unexploded ordnance (UXO) in the sea and on land. This work is often hazardous and sometimes uncovers some significant archaeological finds. Offshore UXO survey The offshore environment provides huge technical challenges, one of which is UXO. And more importantly, which objects are dangerous and which are not? For offshore surveying we use side scan sonar, multibeam sonar, magnetometry and electromagnetometry or EM. In order to work as efficiently as possible we use these survey methods simultaneously. It means less sails for data gathering and an accurate positioning of anomalies found on and underneath the sea bed. The data sets we produce allow us to make an initial preselection of objects that require further investigation by our dive team. A discarded tyre or oil drum for example could have a magnetic signature similar to UXO. The side scan or multibeam image enables us to exclude harmless obstacles from inspection by divers and focus on the suspect UXO targets. In circumstances where a diving operation is unadvisable we have our own ROV at our disposal for close up inspection, identification and preparation for safe removal of UXO.

Following hot on the heels of Hamburg we turn our attention to the eagerly anticipated Offshore Energy Amsterdam. Here is our preview, just for you. The international oil, gas and renewable trade event is just around the corner and before it kicks off, the Offshore WIND Conference (OWC) will take center stage. OWC will again be part of OEEC, taking place on 24 and 25 October also at the Amsterdam RAI, together with speakers from leading companies such as DONG, Siemens and Vattenfall, to further strengthen OEECs connection to renewables. During OWC speakers from the industry will discuss how more business opportunities can be found and how the industry can reach its potential. One such company is Smulders. The company built the first foundation for an offshore wind farm in 2001 and is about to deliver its 1,500th foundation. Having that experience means knowing not all projects will be developed as planned, so Smulders scrutinises all the planned projects prior to bidding to work on them. “My responsibility is to capitalise on this knowledge and really look to specific projects which we can follow and hopefully be awarded within next couple of years. At the moment, that means keeping an eye on

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: Christos Kolliatsas, hydro and renewables director, Mott MacDonald With the potential exception of being a referee or a traffic warden, for the most part, a lender’s engineer or lender’s technical advisor (LTA) may be one of the most polarising professions available. And yet, a professional and competent LTA can bring significant value to a project, save a sponsor millions of pounds and can be personally rewarding. First things first – why do we need an LTA? The need for an LTA stems directly from the involvement of lenders on a project. There are a number of ways of financing a project, one of which is using debt financing. Depending on the level of financing required from the lenders, there will be different types of products that satisfy the funding needs of the sponsors. In this article, we will be looking at project finance or non-recourse finance as it is also known.

The latest developments in blade pitch technology have opened new opportunities for wind turbine manufacturers. In this white paper, Mita-Teknik, one of the world’s leading designer and manufacturer of pitch systems, shares its view of the five key trends of this rapidly evolving technology. It also offers three important insights to keep in mind to make wise pitch system decisions, avoid pitfalls, and choose the right pitch partner. Five key technology trends to watch Preparing for the next energy storage revolution Energy storage is one of the important elements of the pitch system. In the past, all electrical pitch systems used batteries. However, over the last few years, the cost of ultra-capacitors has come down, in large part due to their broad adoption by the automotive industry. Ultra-capacitors, which have the major advantage of much longer maintenance intervals, have progressively taken on traditional batteries.  They are likely to entirely replace batteries within the next few years as they continue to be increasingly cost-competitive. But even as ultra-capacitors are seemingly here to stay, energy storage technology is in such high-speed development that there is no telling what the next innovation will bring. Since energy storage systems are components that wear out relatively quickly, they might

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
