Shell Australia’s Clyde Refinery in Sydney has a number of steam turbine sets to provide process steam and power for the refinery. Turbo-Alternator #3 (5MW) required overhaul and repair to enable it to be returned to service after an extended period of storage.

Our scope of work was to dismantle and inspect the turbine, main valves and governor. We then carried out necessary repairs and reassembly of the set.

The overhaul and repair works were completed on schedule, however during return to service a major HV electrical fault developed with the generator transformer and the unit return to service was abandoned after a decision to close the refinery was announced.
