Major turbine generator shaft realignment

Description
Pickering-1 turbine generator was found to have significant shaft misalignment. The cause of the misalignment was traced to uneven settling of the supporting foundation. The machine was completely realigned by lowering the high-pressure and the first low-pressure turbine and the accompanying bearings. Settlement of foundations was also discovered at other Pickering units, but the conditions of alignment did not warrant major turbine repositioning at the time. Monitoring of foundation movement and turbine generator alignment is continuing. A computer-aided laser alignment instrument has been developed, and will be used for all future turbine generator alignments at Pickering
