One of the worst incidents that can be experienced in a power plant is a generator motoring incident. There are volumes written about these types of incidents as the consequences can sometimes be fairly catastrophic in nature. When this type of incident happens, the station is usually in for a long period of downtime while the rotor is removed, inspected, bundled up, and then transported to a qualified off-site facility for repairs. The average downtime can range from 3 to 6 months depending on the station’s location. Cost can run into the millions of dollars plus it triggers things like business interruption insurance claims. So how does a station deal with such an event? Traditionally, after the event has happened, a plan is set in motion usually following the steps indicated above. In all cases, Insurance underwriters and loss adjusters are involved from the very beginning. Are there other alternatives? Here is a case study on an alternate path we chose to follow in our facility when such an event happened early in 2017, and how the work was performed.
