Customer Challenge

TransAlta, a power generator from Alberta, Canada, was looking to repair combustion hardware non-standard components manufactured by a third party for their GE 7EA gas turbine. TransAlta has nine gas-fired facilities and 1,578 MW of power capacity.

Solution

To ensure that any non-standard parts designs wouldn’t negatively impact performance or durability, the Greenville Service Center collaborated with GE’s Repair Technology Center of Excellence (RTCoE) to map out the repair process and create the right repairs solution. The repair scope and technological process had to be adjusted, with all parts undergoing inspections for non-GE hardware including detailed dimensional measurements, material identification, and patent checks to remain in compliance with intellectual property and GE’s internal integrity program. A novel technological repair process – a braze repair on hard-faced surfaces – was created during this project.

As part of GE’s reverse engineering process for non-GE designs, parts and components that could not be repaired were thoroughly examined to ensure the newly-manufactured replacement parts would meet customer specifications.  

In certain cases, GE was also able to pull GE-designed parts off the shelf that, after inspection, fit within the 3rd party combustion system assembly.  This flexibility, coupled with transparent communication with TransAlta throughout the repair, helped keep budget and schedule in line with TransAlta’s expectations.
