Turbine Operations, Maintenance & Repair Services

AVR Energies provides specialized Operations, Maintenance & Repair Services for steam and gas turbines, backed by experienced field teams and a focus on reliability.

Turbine Operations

Our operations support helps maintain stable, efficient turbine output under all load conditions.

Steam Turbine Operations

Our steam turbine operations include impulse and reaction turbine configuration support, extraction turbine management for feedwater heating, process steam, and cogeneration.

We implement sliding pressure operation to reduce throttling losses and improve part-load efficiency, along with condensing turbine optimization through low exhaust backpressure.

Gas Turbine Operations

Our gas turbine operations cover Brayton cycle performance monitoring and troubleshooting, with quick start-up, shutdown, and peak load operational guidance.

We conduct combustion and exhaust parameter reviews to ensure stable operation under varying load conditions.

Turbine Maintenance

AVR Energies combines time‑based, condition‑based, and predictive techniques to prevent failures and extend equipment life.

Turbine preventive and predictive maintenance

Scheduled inspection of lubrication systems, bearings, couplings, and seals.
Control valve, governor, and protection system functional checks.
Daily, weekly, monthly, and annual inspection plans aligned with operating hours.
Air filter replacement, compressor washing, fuel nozzle inspection, and cooling system verification for Gas Turbines.

Condition Monitoring

Vibration analysis with continuous trend monitoring for early fault detection.
Oil analysis to identify bearing and lube oil wear and contamination.
Thermography and ultrasonic inspection of critical components.
Performance trending of output, heat rate, pressures, and temperatures.

Component Condition Assessment

Visual inspection and non‑destructive testing (UT, MPT, DPT) of blades, rotors, casings, and valves.
Hot gas path examinations on gas turbine liners, transition pieces, and vanes.
Metallurgical analysis for creep, thermal fatigue, and coating deterioration.
