When pitch bearings fail, the repair costs are high. The crane roll alone is often in excess of $100,000. By the time the rotor has been lowered, blade removed, bearing replaced, and the rotor raised back in place, repair costs can pass the $150,000 mark and that figure doesn't include the lost energy value. But with the right data, preventative maintenance of pitch rings costs less than $5,000. Together Nokia, SenseOps, Qualcomm, and OSIsoft have developed an end-to-end solution, integrated with other industrial IT systems, to capture, analyze, and detect pitch bearing problems (and other wind turbine operational issues) before catastrophic failure.
