Although the six 850 kW Vestas turbines in Ngong went into operation in 2009, it has taken years for KenGen to work on expansion. Plans for extensive use of geothermal energy in the East ­African Rift Valley take precedence. In the long run, it is not wind but geothermal energy that is to replace hydropower as the top electricity source. In late July 2014, a Spanish consortium made up of Iberdrola and Gamesa completed the installation of 16 Gamesa turbines, each with a capacity of 850 kW, in Ngong. Nearby, TPF-Econoler of Belgium equipped a wind farm with eight 850 kW Vestas tur- bines. This increases KenGen’s generation capacity in Ngong to 25.5 MW. According to media reports, the inauguration ceremony for both projects is to take place in autumn. General Electric is supplying some 38 turbines of 1.6 MW each for the wind farm on the Kinangop ­Plateau, which is 2,000 m high and located 60 km northwest of Nairobi. Installation started in May 2014. As local media reported in July, construction has been delayed because of a dispute about com- pensation for farmland that the Kinangop Wind Farm consortium intends to use. However, GE Renewable Energy’s General Manager Europe Cliff Harris firmly believes that results will be visible in February 2015.

The consortium is responsible for the financing, installation and operation of the wind farm. In its capacity as an energy company focussing on Africa, Aldwych will supervise the wind farm’s in- stallation and operation, while Vestas will take on the maintenance and, of course, delivery of the wind tur- bines. Kenya Power (KPLC) will buy the electricity gen- erated at a fixed price over a time span of 20 years. It is here that the Kenyan feed-in tariffs for wind energy will pay off; Ethiopia is still waiting for such a policy. Logistical and technical challenges

Still, Ethiopia and Adama 1 will remain the ones to look up to in East Africa for the time being, especially some 153 MW are being installed nearby at Adama 2. Adama is located 99 km southeast of the capital and lies on the main road leading to Djibouti, the small country on Africa’s eastern coast where all goods in- cluding turbines and rotor blades are handled in the port.

By 2030, Kenya and Ethiopia intend to increase power generation capacity by more than tenfold in order to make their vision of becoming emerging mar- kets come true. While Kenya expects 3,000 MW of wind energy capacity to be built, amounting to a share of about 15 % in the generation mix, figures in Ethi- opia reach up to 7,000 MW, which would raise the share of wind power capacity to more than 30 %.

18 Sun & Wind Energy 8+9/2014 Advertorial Universal Transport Company Profile Unstoppable

Various road construction sites on German motorways turned the delivery of six wind turbines into a real challenge for the Universal Transport Group. Even turning manoeuvres on the motorway were necessary.

niversal Transport Group recently provided transport services for a very special wind farm Uproject in the Rhine-Main area. Six new ­hybrid wind turbines were installed near Landau in Rhine- land-Palatinate in August. For the experts at ­Universal Transport, this meant managing a total of 48 trans- ports from four different manufacturing sites. Each wind turbine required eight transports. Why eight transports? The answer lies in the di- mensions and weights of the individual components: Just the tower segments have a length of up to 25.60 m and weigh up to 53 tonnes. In addition, each system has a nacelle that is 9.75 x 4.24 x 3.85 m in size and weighs a strapping 85 tonnes. The three rotor blades are not as heavy, but at 60.06 x 3.62 x 2.77 m per blade, their dimensions are truly impressive. Photos (4): Universal Transport Numerous obstacles along the nearly 580 km long route needed to be overcome. The longest compo- nents for the project also had to cover the longest ­distance. One of the loading sites was located in the Bremen area. The trucks, however, could not head ­directly towards Hanover; they had to take a detour of nearly 150 km via Hamburg. This was due to ­numerous roadwork sites on the A27. The biggest obstacle that the team at Universal Transport had to overcome was located right before the finish line: Just a few kilometres from the wind farm, the motorway exit was currently closed due to roadworks. For this reason, the truck carrying the rotor blades had to leave the mo- torway one exit earlier. Be- Universal Transport Michels cause the exit at that point GmbH & Co.

Working at high altitudes makes special demands on safety. Quality training for workers is all the more important. Photos (2): Mines Rescue

GWO – these three letters have transformed the international wind industry in record time and actually created a standard. Uniform safety training is saving companies lots of money and employees can work anywhere in the world.

Certification pays off

Although the non-profit organization GWO has only 12 members, its standard has spread rapidly. Cur- rently, there are some 60 training centres worldwide offering training in full or partial compliance with the standard and certified in accordance with the criteria of the GWO. Most of these centres are located in ­Europe, but some are in the United States, South ­Korea and even New Zealand. The magic behind this is actually easy to explain, because through its corpo- rate members the GWO represents a huge market force. For instance, companies that want to work for Dong Energy or Siemens, have no chance of setting foot on the job site without GWO-trained employees.

Work without barriers

The new standard helps the industry as a whole be- cause for the first time it offers basic training which is accepted not only by individual manufacturers and other companies in the wind industry, but also by the authorities in the respective countries. In this area, in particular, difficulties have frequently arisen when different or additional occupational safety require- ments were imposed. That made working abroad ­difficult. “The GWO standard is universally accepted as a basis. That has eliminated these barriers. This helps the entire wind industry enormously,” says Jakob Lau Holst of the Danish Wind Industry Organisation. After all, the Danes are heavily invested in this business. “Another advantage is, of course, that the employees get the best training. That means they are tied up for a few days, but then the company does not have to pay for double training anymore,” he adds. Most of these GWO-certified training centres are located in the United Kingdom. Recently, the Mines Rescue Service, together with the manufacturer ­Senvion, commissioned a new wind turbine facility, including an MD 70 wind turbine in order to train service technicians for onshore facilities. Even ­Scotland’s Energy Minister Fergus Ewing made sure not to miss the opening date. At the inauguration, he hit the nail right on the head. “The continued growth in the sector offers a great opportunity for companies such as Mines Rescue Service to expand and ­diversify, and this is helping to support employment and train- ing throughout Scotland.” However, most of the training centres are located on English territory. Mines Rescue now maintains six training centres, two of which are equipped with a wind turbine and specifically tailored to the wind in- dustry. “Of course, the new centre in Crossgates helps companies based in Scotland to save on travel and accommodation costs for their employees. We now offer first rate training,” says Errol Parrish, ­Operations Manager at Mines Rescue, looking at the practical side of the issue. Chip card access

This is particularly true for the European off- shore wind market. “Up to now, although the UK has no manufacturers or a large industry of its own, what it does have is a lot of experience in the construction and operation of offshore wind farms,” says Wim Keen, a managing partner and energy consultant at Antal International. He helps his customers keep an eye out for suitable staff. “Specialists are needed in all phases. This ranges from planning to site surveys, to construction. In these areas, in particular, many specialists come from Belgium, Holland and ­England,” he says. And this is precisely where ­English companies can show their good cards.

24 Sun & Wind Energy 8+9/2014 At the centre of its trade fair presentation, German FWT energy GmbH & Co. KG will be showcasing the 3 MW turbine generation designed by the consulting company W2E. The FWT 3000 is designed for high ­efficiency even at medium and low wind conditions inland, and also for optimised logistics as well as ­international grid compatibility. The turbine was ­designed to meet the requirements of IEC 61400-1, Wind Class 2a, so it has plenty of potential for a ­further performance increase. In the current design, the nominal power of 3 MW is available even at only 12 m/s wind speed. In ­addition to the 90 m and 100 m high steel tower ­version, the new octagonal Ventur hybrid tower (a ­combination of precast concrete sections and steel tubing) with a total of 140 m height will be deployed for the first time. The turbine is based on the drive- train concept that was first implemented in the ­Fuhrländer FL 2500. In this compact drivetrain, the ro- tor is fixed directly to the machine carrier using a three-stage braking/torque bearing. The HybridDrive system from Winergy consists of a transmission unit with two planetary stages (the spur gear stage was no longer required) that increases the rotor rotational speeds from between 6.0 and 16.0 rpm up to a medi- um rotational speed of between 213 and 568 rpm for the permanently excited synchronous generator.

This reduces system downtime and in- creases availability. Siemens is offering platform ­concepts for manufacturing wind turbines that accel- erate the construction process with the help of soft- ware tools and also reduce the number of system components. The Siemens range covers the entire life cycle of a wind turbine, from planning and engineering through manufacture right up to operation. The range includes technologies for automation, visualisation,

Manufacturers of wind turbines have a new transmis- sion platform from Bosch Rexroth available for tur- bines with a rated power between 3 and 4.5 MW. With a compact transmission consisting of two in-line plan- etary and one downstream spur gear stage, the com- pany is focusing on reducing the cost of energy (CoE) as well as increasing reliability using this transmis- sion concept. Adaptations to customer-specific re- quirements are rapidly possible thanks to the ­modular concept, and the time to market is shortened. Rexroth has strongly standardised the parts, which means that they are also available more quickly. Structural changes are also intended to bring ­further benefits – for example the planetary gear takes over the function of the outer planetary bearing ring, which prevents bearing damage caused by a ro- tating conventional outer ring.

Leine Linde Systems GmbH is presenting two new systems for wind turbines, IPMS and ADSR, at their trade fair presentation in their hometown Hamburg. Using a meteorological sensor system that has been tested over many years, the prognostic IPMS ice detection system activates an ice alarm before actual ­icing ­occurs. The alarm is transmitted direct- ly to the system operator, who can then carry out a remote ­visual inspection using the dome camera ­fitted to the wind turbine via a smartphone or ­computer. This is ­also pos­sible at night thanks to spotlights. The ­decision as to whether the system needs to be temporarily shut down can either be made manually from a remote location or automa­ tically using a ­previously-set warning or alarm ­level. The detection system can be adapted to the­ weather conditions on-site by the operator, and can either be built in by the turbine manufacturer or ­retrofitted. ADSR is a diagnosis system for condition analy- sis and prognosis of the remaining service life for wind turbines, which is fitted to a customer-­ indi­vidual slip ring. It continuously analyses the condition of the slip ring and can predict an error before it occurs. This enables operators to plan maintenance better and also to avoid unforeseen standstill times and the ­associated loss of earnings to a large ­extent.

30 Sun & Wind Energy 8+9/2014 On the way to a culture of safety

Today, dozens of employees from a number of different companies often work together at a single wind power site. As a result, safety issues are of great relevance. In the past, the industry tried to ad- dress safety issues with score cards. However, Uwe Sarrazin from GE does not agree with this approach: “It’s not about statistics, it is personal!” Therefore an industry-wide commonly shared HSE ­cultural mind set is needed. A working group implemented by VDMA Power Systems brought to- gether wind turbine manufacturers and subcontractors to initiate a change of culture. In their Wind Industry Safety Culture Conference (25 September from 9 am to 1 pm) the group will discuss the Seven Safety Principles they have adopted:

1. Health and safety of people is valued above all else. 2. All injuries can be prevented – we plan for safety. 3. Management at all levels is accountable for safety and leads by example. 4. Everyone looks out for each other no matter who they work for. 5. Safe behaviour is recognised, acknowledged and praised. 6. ZERO tolerance for safety infringements. 7. Everyone has the courage to STOP any unsafe work.

When the stand for transporting the blades by ship is compared with the stand used for rail transport, the cost advantage of the pragmatic Chinese solution becomes obvious. Apart from the purely technical handling issues, an administrative hurdle remains which, says Ritschel, can only be negotiated with a local partner. “The local freight forwarder took care of many formal- ities for us,” he says. “It also purchased the loading and unloading infrastructure – perhaps this is too big a word to describe the crane that was ordered.” Vestas lowers costs and emissions

FWT Executive Henning Zint considers this transport a pioneering achievement for the industry. “This was uncharted territory for us,” he emphasises. “We had no proven solutions.” For this reason the Chinese forwarding agent, which procured the long transport railcars, carried out some of its own tests on the ­fastening elements prior to the final ­dispatch. The FWT transport was without doubt a ­pioneering achievement. It is not, however, the first

40 Sun & Wind Energy 8+9/2014 rotor blade transport by rail. The real pioneers of such transport are the logistics provider SNCF ­Geodis, the former ­national railway in France, to- gether with global ­market leader Vestas. A full year before the FWT ­transport took place, a train travelled from the ­German Vestas production site of Lauch- hammer to the Danish port of Esbjerg in June 2012, loaded with nine rotor blades. The transport of the 55 m long blades took less than 20 hours to com- plete. This first rail transport of rotor blades in ­Europe spared the company the use of nine tractor trailers and 18 escort vehicles. Furthermore, at 72 hours, the convoy would have ­taken four times longer than the rail transport. “With this innovative approach, we’re not only making an important contribution to reducing ener- gy costs but also to reducing pollution,” says Mette Heileskov Bülow, Vice President of Transport and ­Logistics at Vestas in a press release. SNCF and ­Vestas want to continue to improve cargo traffic ­further ­between the Danish manufacturer’s produc- tion sites. Vestas is doing this, not only with special regard to the environment but also to its funding. “Even at this early stage, we’ve already managed to reduce ­transport costs by up to 15 %,” says Bülow, following the company’s initial experiences. Enercon logistics way ahead

Even though Germany has led the list of wind energy countries for many years and currently has well over 30,000 wind turbines churning out electricity, the Deutsche Bahn subsidiary DB Schenker has so far ­expressed no interest in this business – at least not publicly. A phone call to DB Schenker confirms this impression: “We have the technology for it but have so far not carried out any contracts for transporting rotor blades,” a Deutsche Bahn spokesman says. Why is this so? The answer is strangely nebulous. Somehow, the people at Deutsche Bahn ­headquarters do not seem to know for sure. The spokesman can at least point to an increased interest from DB ­strategists. He also expressed confidence that ­Deutsche Bahn will enter this market very soon. Meanwhile, the debate over who was first to adopt rail logistics is contentious – or, maybe it is not. After all, the German market leader Enercon has owned the e.g.o.o. rail operator as a 100 % subsidiary, since 2007. That is difficult to top. Enercon is using its ­subsidiary to develop a logistics concept that is ­totally unique amongst wind power manufacturers. The company not only owns a railway company but ­also a ship for transporting large components, such as nacelles and rotor blades. The activities of the Enercon rail company also ­include long-distance national transport of goods, as well as the parent company’s own semi-finished and finished products. The wind turbine manufacturer wants to continue expansion of the Enercon rail ­network, and even has its eye on extending beyond national borders. Jörn Iken

In New South Wales, ­Australia, the authorities ordered measurements to be conducted again at three wind farms close to residen- tial areas … Photos (2): NTi Audio

Feeling the noise By using longer blades and fine-tuning them into more aerodynamic shapes, manufacturers are squeezing more and more performance out of their wind turbines. But the background noise caused by stalling continues to grate on some people’s nerves. The phenomenon requires more than just a psychologist.

42 Sun & Wind Energy 8+9/2014 he wind power industry has grown accustomed to conflicts with environmentalists and groups Tof local residents. Noise pollution in particular has long been a hot issue. Whenever this topic arises, the debate quickly moves into the broad field of ­psychology.

Finland is a case in point: Jari Keinänen, Director of the Ministry of Social Affairs and Health, has just declared noise to be the single biggest danger to people residing near wind farms. In June, he called for the current minimum dis- tance of 500 m to be increased to 2,000 m. “It may be possible to go closer, but only when there are reliable figures for an impact assessment”, he said. There is a similar trend in France, where doctors are calling for a minimum distance of 1,500 m. A de- cree from 2011 already introduced stricter rules. In areas where noise emissions are regulated, wind farms may not exceed 35 dBA. To this value 3 to 5 dBA are added depending on the prevailing noise in the surrounding area. The total may only be exceed- ed at fixed times of day. There is also a maximum noise level of between 60 and 70 dBA. These values are measured in a fixed area around each turbine, the radius of which is calculated from the hub height and half the length of the rotor blades. The wind farm must remain within the noise limit at all points with- in this zone. A new problem

Manufacturers like Enercon have started providing specially programmed control systems for such diffi- cult markets. But now the industry is having to deal with a new theme called amplitude modulation (AM) – an abbreviation better known from the frequency settings on radios. The phenomenon appears as a regular “swish” sound at the turbine blades. At least, that is how some local residents describe the noise, which some- times prevents them from sleeping. This is the result of tiny changes each second to an otherwise constant sound level. Experts suspect that the noise is related to the new, aerodynamic designs of rotor blades and their angle to the wind. “It has to do with stalling effects at the blades’ surfaces. The blades of a large wind turbine cut through a high wind profile containing large differ- ences. A lot more research still needs to be done”, says Oliver Bunk, Head of the wind turbine section at Kötter Consulting Engineers. The phenomenon is ­especially vexing because it occurs within the legal noise limits but still leads to problems with residents. “Wind turbines have actually become much quieter in
