At FOX Innovation & Technologies, we are your go-to experts for comprehensive gas turbine services, ensuring your equipment runs at peak efficiency. From power plants to industrial facilities, our tailored services address the unique challenges of maintaining and repairing a wide range of combustion turbine models.
Our Expertise
Our seasoned professionals possess a deep understanding of gas turbine dynamics, backed by technical expertise and extensive experience with both industrial and aero-derivative type gas turbines. We handle a variety of turbine types, including industrial applications and certain aero-derivative models, delivering high-quality, cost-effective solutions.
Specialized Gas Turbine Services
The range of gas turbine repair and maintenance solutions we offer includes:
Hot Gas Path (HGP) Inspections
Routine and critical inspections of combustion liners, transition pieces, fuel nozzles, turbine blades, and vanes. Performed to assess thermal wear and material degradation in high-temperature sections.
Combustion Inspections
Focused review of fuel nozzles, flame detectors, crossfire tubes, and combustion liners. Typically performed on a regular maintenance cycle to ensure proper ignition, combustion, and emissions performance.
Borescope Inspections
Non-invasive inspections using high-resolution video scopes to visually assess internal components such as blades, vanes, combustors, and fuel nozzles — without a full disassembly.
Major Inspections / Overhauls
Full teardown inspections of all major turbine sections, including compressor, combustion, and turbine modules. Typically includes split-line opening, rotor inspection, casing evaluation, and alignment checks.
Inlet & Exhaust Inspections
Visual and dimensional inspection of inlet guide vanes (IGVs), inlet filters, expansion joints, exhaust diffusers, and collector systems. Ensures airflow integrity and structural condition.
Generator Inspections
Inspection of generator rotors, stators, windings, insulation systems, and coupling alignment. Often includes EL-CID, wedge tightness, and impedance/resistance testing.
Gearbox Inspections
Inspection of turbine-to-generator gearboxes for tooth wear, alignment, lubrication systems, seals, and thermal behavior. Common in aero-derivative turbine applications.
Starting Package & Auxiliary System Inspections
Evaluation of starters (motor or gas), turning gear systems, lube oil skids, hydraulic systems, and fuel forwarding skids to ensure startup reliability and safe operation.
Advanced Combustion Turbine Repair Services & Technical Direction
Technical Direction & Oversight
Experienced technical directors provide leadership on-site — guiding outage execution, inspection phases, and hands-on repair work.
Skilled at integrating with plant personnel or blended crews (contracted and internal) to maximize productivity and maintain standards.
Support includes planning, scheduling, procedure development, and quality control throughout the outage.
Contractor Oversight
Quality Control
Combustion & Hot Gas Path Support
Oversight of combustion inspections, HGP component removal and reassembly, and alignment of critical turbine sections.
Close attention to clearances, wear patterns, and metallurgical indicators to avoid premature failure or unplanned downtime.
Precision Balancing & Alignment
Field rotor balancing and coupling alignment services for combustion turbines and driven equipment.
Reduces vibration, bearing wear, and long-term mechanical stress.
Blade Tip Grinding
In-place grinding to restore optimal tip clearance and minimize efficiency loss.
Performed during major inspections or after blade replacement/reshroud.
Field Supervision & Reporting
On-site project leaders maintain detailed records, inspection data, and recommendations for next-interval planning.
Fully integrated with customer QA/QC systems and outage reporting tools.
