Equipment Condition Assessment for Gas Turbines

We conduct gas turbine assessments through a comprehensive protocol covering hot gas path condition, performance, combustion health, and ancillary systems. Borescope inspection covers compressor inlet and accessible compressor stages (leading edge erosion, fouling deposits, FOD damage), combustion section (liner condition, crossfire tubes, transition pieces, fuel nozzle tips), and turbine section (first-stage nozzle and blade condition including coating status, platform oxidation, tip shroud condition, and downstream stages). Performance assessment compares measured output, heat rate, compressor efficiency, and turbine section efficiency to expected values corrected for ambient conditions using OEM correction curves or validated performance models. Combustion health assessment reviews exhaust temperature spread patterns, combustion dynamics data (where monitoring exists), and ignition system function. EOH accounting audit verifies fired hour and start count recording, start-type classification methodology, fuel-type factor application, and current position in the CI/HGPI/major overhaul cycle. Ancillary system assessment covers inlet air system, lube oil system, fuel system, starting system, and enclosure ventilation. Each unit receives a condition report with photographic borescope findings, performance gap quantification, EOH accounting verification, and prioritized recommendations with risk assessment for continued operation versus early maintenance intervention.
