Alstom STF Steam Turbine

The Power Services Group, Inc. field service team recently completed a turnkey B-inspection on an Alstom STF steam turbine rated at 190 megawatts output. The work scope included disassembly, inspection and reassembly of the HP stop valve, HP control valve, IP stop valves, IP control valves, bearings #1 through 5, and the thrust bearing. PSG’s turnkey solution supplied outage management, technical direction, supervision, craft labor, outage tooling, consumables, non-destructive testing, and commissioning and start-up services. The project was aggressively scheduled for 10 days mechanical duration, with a two shift around the clock coverage. Completed safely and without rework, the project was one day ahead of schedule. Another great example of PSG’s expertise with Alstom steam turbines, we provide our clients with a proven and trusted alternative to the OEM.
