Rotating in high speed,
machinery turbines are supported by bearings prevented from grinding against
each other only by thin layers of oil. Such a mechanism is a common sight in
all power plants around the world. In the event that the lubricant
runs out, though, significant damage can occur to the turbine’s bearings due to
the abrupt change in speed. This type of incident calls for months of outage
repairs, impairing production and leading to the loss of millions’ worth of
revenue (especially during demand peaks and spikes).
