Svendborg Rolls Out Yaw Brake Tool
Svendborg Brakes, a supplier of yaw brakes to the global wind industry, has introduced a new yaw brake lifting and installation tool.
According to the company, the new tool aims to improve worker safety and reduce the time taken to maintain yaw brake systems on wind turbines. The tool uses a simple carriage assembly to position, raise and lower brakes to ensure that maintenance engineers minimize any heavy lifting and complete their tasks more efficiently, Svendborg Brakes explains.
The LBS 120 yaw brake lifting and installation tool has been designed to work on brake assemblies with a maximum width of 502 millimeters and a brake disc thickness of 40 millimeters. The tool incorporates a winch mechanism that is used to raise and lower the brake to floor level (with a maximum lifting height of 2 meters). The company notes that the tool is also easy to transport and assemble on-site.
Once the lifting tool has been installed, the original brake can be released – allowing it to rest on a sliding carriage, which is used to position the brake below the winch mechanism used to lower it to the floor. The process is reversed to install the new brake, after which the tool can be repositioned to work on the next brake.
Vaisala Delves Into Collected Wind Data
Vaisala, a provider of environmental and industrial measurements, says its Triton Wind Profiler will soon reach a major milestone of 20 million hours of collected wind data since the solution’s market introduction in 2008. In turn, the company is highlighting trends across wind markets over the past nine years.
According to the company, the solution has been deployed more than 3,700 times in 45 countries and six continents, where Triton has been used to provide wind measurements at sites both under development and in operations. In addition, Triton units have achieved a fleet-wide median up-time of 99.93%, says Vaisala.[adright zone=’190′]
Vaisala says its data illustrates the evolving applications of remote sensing technology by wind energy developers and operators in both established and emerging markets. An analysis of market-specific usage patterns over the past nine years reveals trends that correspond closely to the progress and overall maturity of those markets, the company explains.
In the more established European and U.S. wind markets, there have been close to 2,600 deployments of the Triton, facilitating a range of uses in both site planning and operations. On the planning side, as the height and capacity of modern turbines has increased, the Triton has been widely used as an easier and more cost-effective alternative to static met towers throughout the early phases of development – from site assessment to turbine siting.
Simultaneously, as these markets and their wind projects mature, Triton is increasingly being deployed to help optimize wind assets. The company expects the recent introduction of the International Electrotechnical Commission standard for the use of remote sensors in power performance testing to drive a further increase in deployments at operational projects.
Since 2008, the remote territories and emerging wind markets of Australia, Asia, Africa and Latin America have seen well over 900 Triton deployments. As these nascent markets continue to develop, there is often a greater emphasis on identifying suitable sites for development across terrain that is frequently complex, says Vaisala. Specifically, key emerging markets in which the Triton has seen a significant amount of deployment include Brazil, China and South Africa.
“It’s gratifying to see the range of markets in which Triton continues to be successfully deployed,” says Pascal Storck, head of renewable energy at Vaisala. “As the data bears out, the Triton is built to last; robust enough to perform in a variety of harsh environments the world over; and versatile in contributing to the many stages of a wind farm’s lifetime, spanning both development and operations phases.”
Firm Kicks Manufacturing Into High Gear
In accordance with its V164 manufacturing plan, MHI Vestas is continuing to ramp up production for its 8 MW offshore wind turbine.
According to the company, broad demand for the platform has resulted in a ramp-up of employment in Denmark and the introduction of a dedicated assembly facility for power converter modules (PCMs) at the Port of Esbjerg.
“Since MHI Vestas brought the game-changing V164-8.0 MW turbine to the offshore wind market, we have, as expected, seen extraordinary demand for the platform,” says Robert Borin, chief manufacturing officer for MHI Vestas. “The next phase of our production plan calls for a hiring ramp-up for blade manufacturing in Nakskov, nacelle production in Lindø and power converter modules at the Port of Esbjerg. PCM modules will be assembled in Esbjerg from Q4 2017.”
Construction is now in progress for the 5,600-square-meter facility, which will house PCM manufacturing exclusively for MHI Vestas.
Hempel Introduces New ‘Splash Zone’ Coatings
Hempel has launched two new coating products specifically developed to protect the area known as the splash zone located above the waterline on oil and gas rigs or platforms used in offshore wind.
According to Hempel, the Multistrength 35480 and 35482 coating products are nearly solvent-free and contain a much higher percentage of reactive diluents instead of conventional solvents to create superior cross-linking properties (a chemical reaction that helps harden the coating). This significantly enhances their resistance to corrosion. In addition, the coatings are reinforced with overlapping glass flakes to further enhance their water resistance and strengthen them against physical impact, Hempel notes.
The splash zone suffers from the dual impact of atmospheric and immersion-type corrosion, as well as physical damage, such as abrasion and impact, especially in areas around boat landings, the company notes.

Suzlon Touts Load Factor In New Turbine Model
Suzlon’s S111 120-meter 2.1 MW wind turbine has achieved an approximately 42% plant load factor (PLF) in its first 12 months of operation at the Jamanwada site in the Kutch district of Gujarat, India. The prototype was commissioned in March.
According to Suzlon, the 42% PLF is 20% higher than the 35% PLF achieved by the S97 120-meter turbine in its first 12 months of operation at the same location.
The S111 is the latest addition to Suzlon’s 2.1 MW platform and features doubly fed induction generator technology. With a swept area of 9,852 square meters, the S111 120-meter is designed to optimally harness wind resources at higher altitudes – in turn, making low-wind sites viable.
“It is a proud moment for us to witness the prototype of S111 120-meter 2.1 MW turbine deliver ~42 percent PLF,” comments J.P. Chalasani, CEO of Suzlon Group. “It has successfully generated yield of 7.66 million kWh over the last 12 months. With its reduced levelized cost of energy, cost-effective design and superior performance, S111 120-meter will unlock unviable sites and set new benchmarks in the Indian wind industry.”
Nordex Sells New Units In Medium-, Low-Wind Areas
The Nordex Group says it is widening its range of efficient solutions for medium- and light-wind locations with the addition of two new turbine models.
According to Nordex, the N131/3900 is an enhanced version of the N131/3600 from the Generation Delta range. With the N131/3900, the company is raising the nominal output of its most powerful light-wind turbine by 8%, thus enabling yield gains of between 1% and 4% to be achieved depending on the location.
Despite the increased output, acoustic emissions could be kept low at 106.2 decibels by using serrations at the rear edges of the blade. Moreover, the company says noise-optimized operation modes are available for the turbine, meaning that it can also be used in sound-sensitive locations.
Nordex is offering the N131/3900 with hub heights of up to 134 meters. As reported, the turbine will be available in North America and large parts of Europe from January 2018. The first N131/3900 will be installed in Germany at the end of 2017.
Nordex says it is now also offering the N131/3600 for locations with medium wind speeds. The N131/3600 was launched in autumn 2016 as a turbine for light-wind locations. It has now been assigned to a higher wind class, allowing Nordex to supplement its range with a larger rotor for medium-wind-speed locations.
According to the company, the rotor sweep in this wind class is 25% greater than that of the medium-wind turbine N117/3600. As a result, the turbine yield is up to 15% higher depending on the conditions prevailing at the location.
This has been made possible thanks to adjustments to two variables: First, the turbulence curves are tailored to meet the target markets, meaning that the turbine is able to meet actual turbulence requirements of the specific location. Second, the operations management has become even more intelligent, permitting load-optimized turbine control by means of individual pitch control.
Nordex says the N131/3600 is ideally suited for locations characterized by medium-wind conditions in Germany, Scandinavia and Turkey. The first turbine of this type was installed in January 2017 close to Husum in northern Germany. The N131/3600 will be available in hub heights of between 84 and 134 meters.
