Gas turbines are critical assets in power generation and industrial operations. Operating under extreme temperatures, pressures, and rotational speeds, even minor abnormalities can quickly escalate into major failures. In most cases, gas turbines do not fail without warning—they show clear signs that maintenance is urgently required.
Recognizing these warning signs early helps prevent forced outages, reduce repair costs, and protect long-term equipment reliability.
Gas turbines are precision-balanced machines. Any increase in vibration levels or unusual noise is a strong indicator of mechanical distress.
Unchecked vibration accelerates wear across multiple components, turning minor issues into costly failures.
A noticeable decline in power output or thermal efficiency often signals underlying performance issues—sometimes without triggering alarms.
📉 A 2–3% loss in gas turbine efficiency can increase annual fuel costs by hundreds of thousands of dollars, depending on turbine size and operating hours.
Exhaust Gas Temperature is a critical indicator of turbine health. Sudden spikes, uneven EGT spread, or sustained high temperatures indicate internal problems.
EGT Behavior | Potential Risk |
Sudden spike | Fuel or combustion fault |
Uneven temperature spread | Burner or liner damage |
Sustained high EGT | Turbine blade overheating |
Operating at elevated EGT levels significantly reduces the life of hot-gas-path components and increases the risk of forced outages.
The lubrication system is the turbine’s lifeline. Changes in lube oil condition often provide the earliest indication of internal wear or system issues.
🛢️ More than 70% of bearing failures are linked to lubrication-related issues, many of which are detectable through routine oil monitoring.
ATTS Inc. provides professional lube oil monitoring, filtration, and condition assessment services, helping gas turbine operators identify lubrication-related risks before failures occur.
Repeated alarms or trips are not nuisance events—they indicate unresolved problems within the turbine or its control systems.
Ignoring recurring alarms increases the likelihood of unplanned shutdowns and safety risks.
Proactive Maintenance | Reactive Maintenance |
Planned inspections | Emergency shutdowns |
Lower repair costs | Major component replacement |
Improved safety | Higher operational risk |
Extended equipment life | Accelerated wear |
