Specialized inspections for turbines

The majority of the inspections listed below are specialized inspections developed by our company to meet the needs of the utilities.

• 7FA TIL 1509-1 inspections in 12 hours or less (also available on the 7EAs)

• 7FA remote INSITU R-0 and R-1 platform ultrasonic inspections to identify cracks in both the standard blades and P-Cut blades (100% of the blades can be inspected)
• 7FA R-1 platform eddy current inspections to identify surface cracks on the platforms
• Remote shim removal and or grinding on the S-0 through S-2 compressor shims per TIL 1562 (other companies require compressor disassembly)

Standard borescope inspection

Our standard borescope inspection is designed to provide users with a true representation of the unit’s condition. We inspect the compressors in four locations from the inlet, the combustion section, the turbine and the exhaust.

On the 7FA every stage of the compressor is inspected. We also provide a list of supplemental inspections on the 7FA that allows users to add additional inspection items to the work scope: ie number one bearing lift oil lines, full transition piece impingement sleeve inspection, etc.
