SGS Article on Ensuring Reliable Operations of Wind Turbines Featured in Renewable Energy Technology

SGS article entitled "Ensuring Reliable Operations of Wind Turbines," written by Olaf Robenek and Nils Dreischerf, wind turbine inspectors from SGS, was featured in the February 2012 issue of Renewable Energy Technology magazine.

The February 2012 edition of the Renewable Energy Technology magazine, which is aimed at senior professionals in emerging markets of renewable energy industries, features an article by Olaf Robenek and Nils Dreischerf, SGS's wind turbine inspectors, entitled "Ensuring Reliable Operations of Wind Turbines."

In the article, SGS's experts explore the significance of regular in-service inspections for wind farm projects conducted by an experienced third-party company. In-service inspections are the most effective method for ensuring the successful performance of a wind farm, since they can detect the imminent failure of a wind turbine's critical components at an early stage, thus minimizing the risk of costly repair periods. With regular in-service inspections, the downtime of a wind turbine can be considerably reduced, which in turn facilitates the profitable operation of a wind farm with sustainable operational costs and the anticipated return on investment.

Due to an increasing number of installed wind turbines and the potential for major failure of critical components, the necessity of in-service inspections should not be underestimated. Nevertheless, in-service inspections only represent a value-added service to the customer when they are conducted by a reliable third-party company.

In-service inspections, including thermographic inspection, vibration measurement of the drive train and oil analysis, endoscope inspection, blade inspection, rotor imbalance, blade pitch, angle measurement and rope access, cover a series of activities in which the various components of a wind turbine are regularly inspected and monitored throughout its entire operational lifetime. Using a range of diverse inspection methods and analyses ensures that any unexpected degradation from normal conditions is detected as early as possible, in order to prevent consequential damage to the wind turbine.

As the world's leading inspection, verification, testing and certification company, SGS is well-positioned to provide a comprehensive portfolio of in-service inspections for wind farm projects on a regular basis. Having an international presence with more than 70,000 employees and over 1,350 laboratories, SGS is familiar with the local environment, circumstances, languages, laws and regulations.
