Gas Turbine Inspection and Overhaul

Comision Federal de Electricidad (CFE)
Chihuahua  Combined Cycle Plant
Chihuahua, Mexico

Original Manufacturer of Equipment:

Scope of Service Project:

The Mitsubishi-built, two-unit combined-cycle plant is four years old and is one of the most efficient plants of its kind in the world.  Utility management elected to use a March-April 2004 outage window to execute a complete turbine major inspection of both gas turbines during overlapping intervals.

Under an existing long-term service agreement with CFE, Mitsubishi assumed the role of lead outage contractor, providing project management, technical resources and replacement components.

Both turbine outages had to be completed within the previously planned 40 day balance-of-plant outage window.  Compact power deck footprints and a lay down area designed for single-unit outages meant that service operations for each turbine would have to be staggered, and lay down activities performed out-of-building.

Results:

Not only did Mitsubishi accomplish a double-major outage in a very difficult space, with some very challenging logistics…but it was done on a time schedule only fractionally longer than a typical single outage.  Each turbine was completed in 28 days.  Total outage completion was two days ahead of schedule, and performance guarantees for major outage duration were exceeded.

Video Summary of this Outage:  "Rising to the Challenge"
