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.

    Nordex benefits from rising demand in the second quarter of 2017 08/03/2017
    ...) and was thus largely stable compared with the same period in the previous year. Output improved in both turbine assembly and rotor blade production in the period under review. Turbine assembly output came to 1,536 MW (H1/2016: 1,298 MW). This growth of a more than 18 percent is largely due to the production of wind power systems in Spain, where Nordex addresses non-European market demand. Rotor blade production increased by 30 percent in the first half of the year, reflecting preparations for non-European projects scheduled for short-term completion. At EUR 117.5 million (H1/2016: EUR 136.6 million), operating earnings before interest, taxes, depreciation and amortisation met expectations, translating into a Group EBITDA margin of 7.8 percent. This performance was underpinned by the good average margin on projects under construction, which is also reflected in the increase in the gross margin to 27.2 percent (H1/2016: 24.8 percent). Consolidated profit came to EUR 22.6 million (H1/2016: EUR 51.0 million). As expected, the working capital ratio rose to 9.8 percent as of the reporting date due to preparations for numerous projects to be completed in the short term. As well as this, customer prepayments were down on the previous year. At the same time, order intake rose substantially during the year. In the second quarter, Nordex received new orders worth EUR 572 Mio. All told, order intake in the first half of the year came to EUR 905 million but were down on the previous year (H1/2016: EUR 1,330 million). This was mainly due to more muted new business in Europe, which accounted for 43 percent of total order intake (H1/2016: 68 percent). Furthermore, order intake from non-European markets rose as a percentage of the total as well as in absolute terms. As of 30 June 2017, Nordex had an order backlog including service business of a total of EUR 3.6 billion, which forms the basis for the confirmation of the full-year targets for 2017. Thus, sales are expected to come within a range of EUR 3.1 to 3.3 billion, accompanied by an EBITDA margin of between 7.8 and 8.2 percent. The Management Board expects the working capital ratio to drop to 5 - 7 percent in the second half of the year particularly due to prepayments received on new orders. “Our focus is now on landing the projects that we are in an inch of getting. And we are responding to the changes in business volumes by stepping up cost discipline to support our profitability,” says Nordex CEO José Luis Blanco. ...

    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. ...
