Rotor Blade Control

Around 27.000 wind turbines of different sizes and power have been installed in Germany. Regular maintenance work is required for granting their smooth operation inclusive assessment, maintenance and repair of the rotor blades.

The blades can be accessed by complex service platforms, granting short setting-up times irrespective of hub height. Thanks to special sling points and suspension to the machine nacelle the blades can be turned further anytime, allowing a fast completion of work. Major repairs can be executed parallely at different blade positions. Down times can be reduced to a minimum.

Blade assessments are made by high workers well trained and certified in rope access technology allowing a fast and cost saving execution of work. Rope access is both profitable for damage documentation and control and maintenance of lightning protection system.

The manifold blade controls include tip maintenance and control of drainage holes, as well. Aerodynamic parts are controlled for fixity and completeness.

The strong blade surface wear requires a regular control. Cracks, voids, lightning damages, gelcoat damages, installation or handling damages and delamination are possible symptoms.

The inner blade is examined as far as accessible. This includes visual control of hydraulic cylinders and tubes as well as burn marks or lightning strike. The tip rope is controled for tight fit and is adjusted where needed. Residual adhevises are removed and lamination and adhesive seams are controled.

    Zigzag Provides More Yield 02.02.2017
    ..., LM Wind Power and the ECN have developed a new rotor blade tip, which can increase the power generation of a farm between two and six percent... results on the 80m rotor blades showed that an increased wind power performance of up to six percent can be achieved through the special blade tips. With a new method, the ECN was also able to measure relatively low power increases. Ozlem makes it clear that the end of research is still far from being achieved and continues to rely on the interaction of the research center with LM Wind Power: “Great results are encouraging to continue designing models and demonstrating blade tips. Together we aim to lower costs of wind energy.” (The graph on the right shows what the ECN is doing in the area of wind energy research.) The noise levels of offshore turbines thus modified compared to onshore systems have not been published in detail yet. Since there are high requirements of noise reduction with a limit of 160 decibels during the installation of the foundations (at least in Germany), it remains to be seen whether the noise of the zigzag tips has an impact on the local fauna and would therefore have to be regulated. ...

    Siemens officially inaugurates new wind turbine blade factory in the British city of Hull 02.12.2016
    ...Siemens has officially inaugurated the new rotor blade factory for offshore wind turbines in Hull, UK, in an event attended by the Secretary of State for Business, Energy and Industrial Strategy Greg Clark and representatives of the local community. The site at Alexandra Docks has been transformed in under two years from a derelict industrial wasteland to a busy high-tech manufacturing hub. Now, the state-of-the-art factory has completed the first 75-meter-long blades which are currently stored on racks on site. Shipping to the first offshore wind project Race Bank is expected in early 2017. "Our new factory in Hull which we are today officially inaugurating is located in one of the most significant markets for offshore wind power and will produce rotor blades for our 7 and 8-megawatt wind turbines," said Michael Hannibal, CEO Offshore of Siemens Wind Power. "The new manufacturing plant is part of our efforts to establish offshore wind power as a key pillar of a sustainable energy mix in Europe. At the same time we are creating 1,000 attractive jobs here and thereby supporting sustainable regeneration in the Humber region." With its partner Associated British Ports (ABP), Siemens is investing £310 million in Hull to create a world-class center for offshore wind manufacturing, assembly and logistics. The centerpiece of the investment, the wind turbine blade factory, is now fully operational. The full Alexandra Dock site, including a new harbor for pre-assembly and load-out of wind turbine components, will be fully on stream in 2017. Siemens had employed almost 700 people in Hull so far. A further 100 permanent staff are employed at Alexandra Dock working for Siemens’ suppliers and additional recruitment up to a total of 1,000 people will continue into 2017 as the site becomes fully operational. Hundreds more jobs have been created during construction and in the supply chain. The new production site has an area of 540,000 square meters, including an area reclaimed from a wet dock. The new factory itself covers 40,000 square meters and has an optimized material flow based on the Siemens Production System (SPS). Storage, supply chain and assembly work are interconnected with modern database systems to produce 75–meter-long rotor blades for offshore wind turbines of the seven and eight-megawatt class. Offshore wind manufacturing sites such as Hull in the UK or Cuxhaven in Germany are efficiently linked by new transport vessels and embedded in Siemens’ logistics concept with the goal to leverage innovation and industrialization on the way to lowering the costs of offshore wind energy. A key element of the concept is an improved transport solution, utilizing dual-purpose transport vessels to avoid both heavy component lifting through innovative Ro/Ro handling and cost intensive shipping of heavy components. There is a growing market for wind turbines designed for erection off shore. Offshore wind power plants are currently being built primarily in the North Sea and Baltic Sea off Europe's northern coastline. However, wind power projects are being developed in other regions as well, such as along the East Coast of the United States and in Asia off the coast of China and Taiwan. ...
