Presentation

Title: Investigation and return to service of a 660MW unit following a mass loss from a coupling

Synopsis: In 2023, a power station faced significant challenges during the return-to-service process following an off-load refuelling outage. Excessive vibrations during the run-up led to a dynamic investigation to identify the root cause. 

Post-shutdown, it was discovered that a 6.5 kg nut from a hydraulically tensioned coupling bolt had detached, causing severe damage to the pedestal and associated components. 

This presentation will detail the dynamic analysis and rectification work performed using advanced 3D scanning technology, which enabled the unit to return to service without additional in-situ balancing. The session will also cover the lessons learned from this complex repair process.
