Can 7FA Repairs Be Done in the Field?
When a 7FA gas turbine experiences an unplanned outage, time is of the essence. Operators seek swift, dependable solutions to restore their units. Fortunately, many 7FA field repairs can be executed directly at the plant site. This approach minimizes downtime and reduces expenses associated with transporting heavy components elsewhere. We are based in Houston, Texas,...

Shaft Runout & Bow: Causes, Detection, Correction in Turbines
When a turbine shaft that should rotate true begins to wobble, even slightly, the consequences ripple through every downstream component. Maintenance teams spend significant time chasing vibration symptoms that trace back to two root-level geometric problems: shaft runout and shaft bow. Left unresolved, both conditions escalate — often requiring rotor repair that could have been avoided...

Optimizing GE 7FA Part Load Operations
Running a gas turbine at full capacity is relatively straightforward — push the unit to base load, maintain firing temperature, and let the machine operate within its design envelope. Part load operation is a different challenge entirely. Think of it like driving a high-performance sports car through a school zone at 25 miles per hour....
