Wind Edition 7 Review Facts & Figures

Analysts and market researchers produce a vast number of studies on how the different sectors of renewable energies have developed both globally or in selected countries. They send out their own projections on how markets for all kinds of renewable energies are set to facts & develop. Facts and figures come into our mailbox in an endless stream hard to overlook. SUN & WIND ENERGY has selected several interesting ones and presents you our new figures Facts & Figures section.

The Jeffreys Bay Wind Park concept, as one of 16 wind farms already in the country, originated from the ­Nelson Mandela Metropolitan ­University of Port ­Elizabeth. Port Elizabeth, located approx. 70 km away from the wind farm, is known in South Africa as the “windy city”. When awarding Jeffreys Bay, some rules for ownership were prescribed. For example, 40 % of the ownership interests in the wind farm must be in South African hands, of which 2.5 % must be in the ­local vicinity of the wind farm. And 20 % of the owners must be black South Africans. Also encouraged is awarding companies that are owned by black women.

Wind power expansion there must be closely linked to grid expansion.

This is the decisive difference to many events in Europe. When it comes to the expansion of renewable ­energy, Europe is far ahead of the Land of the Rising Sun, though – which the Japanese also acknowledge. “Japan keeps on looking at Germany, Spain, France and the USA and asks itself which role model it should follow,” says Yasuhiro Matsuyama, also from METI. Serving its own market

When it comes to offshore wind power it is only ­partially doing this, however. Here you get the feeling that Japan would rather do its own thing, not least be- cause the geographical conditions are considerably different from in Europe. Monopiles would not get very far in the deep waters off Japan’s coast, which is why the country is preferring to go straight for floating wind turbines. These are also possibly better ­protected against the frequent typhoons. Having your own technology brings the advantage that home companies can profit from the new market. Japan is traditionally a country with a technological edge and it would be absurd to not develop its own offshore wind power and have to leave its own market to foreign companies. Japanese companies are thus increasingly positioning themselves also as suppliers of onshore turbines. Particularly generators and yaw gears are meanwhile being manufactured by Japanese companies. The Japanese wind power industry is not hiding away, it is presenting itself confidently. Katharina Garus

The UAV is equipped Photo: Batcam with an anti-collision system to prevent collisions with, for example, a rotor blade in strong winds. “Even at wind speeds of 12 m/s, the drone is stable in flight and the camera delivers incredibly sharp photos,” Project Manager Marcel Bruins reported ­after a test phase. When it comes to operation and costs, however, more trust is put into ground-supported camera sys- tems, which are less susceptible to wind and supply photos of an equally brilliant quality. GEV Wind ­Power of England and their technology partner Cornis SAS of France, for example, have begun selling the ­Panoblade Inspection System for camera-based ro- tor blade inspection. First, the system takes pictures of each section of the blades of a turbine that has been brought to a halt before using algorithms to stitch them together into a full blade. Next, experts examine the results and record their findings in a planning tool for actual maintenance tasks. This process aims to shorten the downtimes in the sum- mer repair season by three to five days and, accord- ing to GEV, increase revenue by one to two percent. “We recognised the cost-effective and simple advan- tages of utilising the remote blade inspection ­system. With only one operator required to inspect up to five onshore turbines per day or three offshore turbines, this system will offer exceptional savings in both time and money,” says Alastair Gadney, Projects ­Director at GEV. Specialists are essential

Because visual checks of the blades are only one side of the coin, specialists must be called in to do the ac- tual work.

Trials on test rigs demonstrate that factory-made coatings actually do not last very long. In this respect, the Poly Tech A/S helicopter test rig in Denmark is re- garded as a Mecca, because its results are generally accepted in the industry. The models are accelerated to as much as 150 m/s and simultaneously being

While some coatings wear off BLADE REPAIRS after just two hours, one product from BASF was able to withstand the constant stress for 18 hours. Although major companies such as BASF and LM Wind Power have their own test stands, uniform stand- ards are lacking for replicable test runs and the proce- dures to be applied on the test rigs. The latter are to be defined by an international commission. One op- tion is helicopter test rigs, on which the blades to be tested are accelerated to extreme speeds and shot at with rain drops. This type of test rig is avail­able in the US, the UK, Germany and, as previously mentioned, Denmark. Another possibility is high-pressure jets of water that are shot at the blades. In both cases, the ­methods used are intended to come very close to real condi- tions and quickly provide data on the material’s ­durability. “What the coating industry has been lack- ing for this particular field are test procedures and test rigs, specially developed for simulating damage from rain erosion in the lab in a way that is replic­ able,” says Susanne Bender of the German Institut für Lacke und Farben in Magdeburg.

Wind Edition spotlight Rotor blades access systems Standing firmly in airy heights Mobile work platforms are suitable for repair work on rotor blades. Regardless of hub height, they allow high-quality, safe and comfortable work to be performed on all types of systems.

epair and maintenance of rotor blades is now a per- manent fixture in the maintenance concept for eve- Rry wind turbine. However, accessing the rotor bla- des is by no means trivial. Hanging on a rope to do main- tenance and repair tasks is one ­option, but it is not parti- cularly comfortable and very dependent on wind conditions. For this reason, rotor blade access systems have es- tablished themselves as an alternative means of access. They consist of platforms hanging from ropes that are pulled up along the tower of a wind turbine. At the height of the vertically downward-pointing ­rotor blade, they usu- ally push themselves away from the tower and closer to the rotor blade via an ­extensible framework or a ­telescopic arm. Depending on the model, the working platforms then more or less enclose the rotor blade. With the work plat- form in this position, repairs can be engaged in much more comfortably than when hanging from a rope. Larger re- pairs can be performed at different points on the ­rotor blade by several technicians at the same time. This allows for wind turbine downtime to be reduced to a minimum. All-round maintenance of the blade

Goracon Systemtechnik GmbH, for example, has a clever solution on offer. Their rotor blade access ­system G- bladeaccess RBA-01 can be adapted to different blade shapes very flexibly because it consists of four platform segments arranged in a diamond shape on a base frame. The angle of the individual platform segments in relation- ship to one another can be adjusted, allowing the platform to be optimally adapted to any rotor blade shape. The plat- form ­system ­encloses the rotor blade fully, enabling work to be carried out on the entire blade from all sides. This is also the case with the BLADElift from ­Hailo-Werk Rudolf Loh GmbH & Co. KG, even if the platform‘s U-shape might initially seem to suggest otherwise. Hailo chose the Using rotor blade open U-shape to ­facilitate approaching the rotor blade with access systems, seve- the platform.

Once at the blade, the front ends of the BLADElift tilt together, making it possible to work on the blade from all sides. Photo: Hailo wing platforms enclose the rotor blade, making it ­possible to work on the blade from all sides. An open U-shape is also utilised by the ­internationally active Tractel Group. It has two different models for work- ing on rotor blades in its product range. The hoists can not only be attached inside of the nacelle; they can also be at- tached to the two upper rotor blades using ropes. The plat- form can be installed and is ready for use in less than two hours, according to the manufacturer. With the Tractel sys- tem, the hoist position pushes the platform up against the BLADEBLADE tower for higher stability.

Specialists in servicing wind turbines are being sought in many countries. Photo Siemens A piece of the action

Factories and wind farms pour money into the coffers, create new jobs and arouse desires. Politicians are making an extra effort to provide training for bright minds and qualified workers because in Europe alone there is a need for more than 7,000 service technicians.

n terms of policy, many countries are rolling out the proverbial red carpet for Iwind energy. The young technology has several arguments on its side. At least on land, it is an inexpensive source of energy that wonderfully fulfils the climate protec- tion goals of governments and does not overburden consumers with electricity fees. In addition, the growth of wind energy creates jobs and adds value. No wonder then that politicians are putting a lot of thought into location advan- tages for companies willing to settle. “We are investing in new research centres, and in that we have commerce on our side. Ireland has great potential. With the development of ­science, we might be able to influence the de- velopment of technology worldwide,” stated Damien English, Irish Minister for Skills, Research and Innovation. Specifically, he is talking about twelve new research centres, in which Ireland has invested € 19 million and industry € 10 million. This fits well with the Celtic Tiger’s new strategy of concentrating on innovation for growth and new jobs. This is also true for five new world-class research centres, which Ireland will invest € 155 million in, if the industry brings a further € 90 million to the table.

34 Sun & Wind Energy 2/2015 Those research centres may not have anything to Funding attracts companies do with wind energy directly, but they do show a clear trend: Ireland wants to re-position itself as a research The English neighbours are also working on this.

36 Sun & Wind Energy 2/2015 students with its campaign “Shape the Future of Wind Energy Research”. The growing network with nearly 40 members from research institutions and universities offers a variety of training and study op- portunities in the broad field of wind energy. Yearly seminars for postdoctoral researchers and a ­biannual international conference guarantee knowledge trans- fer. The offering is completed by the seminars and conferences organized by the miscellaneous ­members. Without a doubt the flagship of the EAWE is the Erasmus Mundus courses European Wind Energy Master (Msc degree). This two-year study programme is jointly provided by the Delft University of ­Technology, the University of Oldenburg, the ­Technical University of Denmark (DTU), and the Norwegian ­University of Science and Technology. These are ­prestigious addresses in wind energy research. The English language programme offers four specializa- tion areas and ends with a double degree. “In addi- tion to training, the EAWE mainly engages in the field of ­research, said James Mann, President of EAWE and Professor at DTU. “The members cooperate in various research programmes and work towards a common ­long-term research strategy to further advance ­research at European level,” he added. Therefore, the organisation is currently preparing a separate ­scientific journal for wind energy research.

Whether on land or far out at sea, in calm or windy conditions, in a cold or hot climate – Senvion provides the right turbine for your location.

In our 25-year history, we have created a wide range of onshore and offshore turbines for all wind classes with many different tower heights. We have experience with large-scale and small-scale projects alike. We develop, produce and sell wind turbines – with rated outputs of 2 to 6.15 megawatts and rotor diameters of 82 to 152 metres. In addition, we provide project-specifi c solutions in the areas of turnkey solutions, service and maintenance, transport and installation along with foundation planning and construction. To date, we have constructed facilities worldwide with a total output of more than 10 gigawatts.

Together we turn wind into a powerful direction.
