Vestas' latest and greatest offshore wind turbine, the 8 MW V164, is designed to operate for a quarter century with minimal upkeep. To ensure that these massive turbines (their blade sweep area is equal to three football fields) are robust enough for 25 years of service in the North Atlantic, Vestas tortures its housings atop an equally gargantuan test bed.

The 137-foot-long, 30-foot-wide test bench has recently begun operation at Vestas’ global testing center in Aarhus, Denmark. But before the bench was installed, construction crews had to first lay a 164-foot deep concrete foundation to support the device's 700-ton mass—that's including the 20 MW (26,820 HP) motors, wind simulator, and cadre of generators.


The bench is so large that it can easily accommodate a full V164 nacelle, which measures 24 feet tall, 78 feet long, and weighs close to 400 tons. Once on the bench, the nacelles are put through a rigorous testing simulation to judge the device's reliability and ruggedness over its service life including stress testing the gearbox, main shaft, and generator.

It's safe to say that when we finally build jaegers, this is where they'll go through quality control. [CleanTechnica - NA Windpower - Vestas - Central Energie]
