A Manual Process Sampling Solution for In-Service PAT Inspection of Wind Turbine Blade Bearing Lubricants
DOI: 10.62178/sst.004.009
Abstract
Wind turbine failure is causing debilitating equipment/operational downtime and is always very costly due to the exceptional efforts required for repair or replacement – especially so for offshore turbines. Condition based monitoring (CBM) of grease lubricated turbine components (main and blade bearings) can greatly improve turbine reliability and reduce costs when properly applied. In-service monitoring of grease lubricated bearings is a win-win benefit at all levels. But is it possible to apply a PAT approach for in-service grease monitoring to develop a reliable warning system before breakdown? Alas, not directly - it turns out that certain necessary modifications to the
standard PAT concept are needed. Here we present the development history of a manual process sampling solution for in-service PAT inspection and monitoring of grease lubricated main components in wind turbines.
