Streamline operations with GE Vernova's Monitoring and Diagnostic (M&D) Services

Our M&D Services team identified abnormal exhaust spreads that pointed to potential fuel flow issues in specific combustion cans. Based on our recommendations, the plant inspected the gas fuel passages and discovered debris partially blocking the fuel nozzle in can #18.

By removing the contamination and tracing its source, the site restored normal combustion performance, which eliminated the hot and cold spots and returned the unit to optimal operation.

The result? Faster issue detection, targeted inspections, and a smooth return to service—all enabled by GE Vernova’s Monitoring & Diagnostics expertise.

When a D11 steam turbine unexpectedly tripped, GE Vernova’s M&D Services team leapt into action. Our Tier 1 engineers quickly flagged an anomalous proximity sensor reading (BB2Y) and comparing data across adjacent sensors (BB2X) and temperature trends, determined the issue was a false alarm—not a mechanical failure.

We recommended inspecting sensor wiring and calibration before restarting the unit. The site discovered water intrusion in the junction box caused the errant readings.

The result: No further high vibration trips.

The M&D Services team identified that a 7E gas turbine shutdown trip was caused by a delayed CBV response, not a mechanical fault. By pinpointing the valve timing issue and ruling out costly hardware damage, the team gave the customer clarity on the true cause of the event.

With targeted recommendations—including valve actuation testing, solenoid checks, and adjustments to instrument air conditions—the site resolved the problem and restored the unit to service.

The result: No repeat trips, avoided downtime, and confidence in reliable operation.

When real-time data showed a 25–30 °F drop in one HRSG stack exhaust temperature (while the companion thermocouple remained stable), GE Vernova’s M&D Services team recognized a potential tube leak—not a sensor fault. Their timely insight prompted targeted inspections that confirmed a leak caused by thermal stress and cycling.

M&D Services helped the site identify the root cause swiftly, enabling a focused repair that avoided an extended outage. This lowered downtime, improved HRSG reliability, and reduced the risk of future runbacks or trips.

When an H84 generator triggered a high stator temperature alert, GE Vernova’s M&D Services team quickly determined the anomaly was due to a faulty sensor, not overheating. Their analysis guided the site to inspect wiring, connections, and RTD calibration. Once corrected, the sensor returned to accurate performance—avoiding unnecessary maintenance and restoring confidence in the unit.

GE Vernova’s M&D Services provide real-time insights that separate false alarms from true issues, helping customers act quickly, reduce downtime, and keep generators running safely and efficiently.
