Featured Article: Premature Bearing Failures; The Achilles Heel of Gearboxes

Published on July 11, 2017

Wind turbine gearboxes are designed to last 20 years. However, wind operators often experience gearbox failure rates of up to 50% across the lifetime of their fleets. If component fatigue, fretting or wear is caught early enough, an operator can mitigate consequential damage and prevent catastrophic gearbox failure. If the window of prevention is missed, however, the operator can incur costly repairs between $200,000-$500,000 for just the gearbox system. This includes a minimum of two weeks of lost revenue from asset downtime, the cost of the gearbox replacement, and additional crane and labor costs.

Mitigate Costly Main Bearing Failures with New DigitalClone Live Capabilities

Published on April 20, 2017

Main bearings deployed in the field may fail after 6 to 10 years of operation, leading to costly $150,000 to $300,000+ replacements. If an operator experiences multiple main bearing failures in a budget year, that can bleed heavily into profit margins.
