Keeping CCGT plants running: one tool to detect leaks of any gas.
Avoid unplanned outages with acoustic cameras that detect all leak types across gas turbines, HRSGs, steam turbines, and BoP, including condensers, during live operation.

Combined cycle plants: maximum complexity, maximum consequences of undetected leaks
Combined Cycle Gas Turbine (CCGT) plants integrate gas turbines, heat recovery steam generators (HRSGs), steam turbines, condensers, and compressed air systems into a single highly interconnected facility. This complexity creates a wide variety of leak types — methane in the fuel system, compressed air across instrumentation and control lines, steam throughout the HRSG and turbine casings, and vacuum air ingress into the condenser — each with direct consequences on output and availability.
Distran acoustic cameras detect all gas types with a single device, from a safe distance, without stopping production. A two-day survey during live operations can uncover dozens of leaks invisible to conventional tools, and generate a prioritized repair schedule for the next planned outage.
Inspect During Live Operations
Survey the plant while it runs: no production loss, no need to wait for the next outage. Leaks are found and documented so repairs can be scheduled efficiently.
All Leak Types in One Survey
Methane, compressed air, steam, vacuum (air ingress), and hydrogen on generators — all detected with one acoustic camera. No tool switching, no blind spots.
Cover Large Sites Quickly
A single operator scans gas turbines, HRSGs, condensers, and compressed air systems far faster than soap spray or helium detection methods — without entering hot or hazardous areas.
Reach Difficult Equipment
Inspect from 0.3 to 100 m. Turbine enclosures, elevated HRSG piping, and condenser systems are covered from the ground — no scaffolding, no lifts, no hot-space entry.
Quantify and Prioritize Repairs
Real-time leak rate data lets maintenance teams rank findings by size and impact. Audalytics generates a ready-to-use report with images, video, and leak rates for every finding.
Protect Condenser Vacuum
Even small vacuum losses degrade heat rate and output. A 0.35 in Hg improvement in condenser vacuum can save up to 100,000 USD per year on an 827 MW plant.
ENGIE Al Ezzel — 77 Leaks Found in 5 Days at a 950 MW CCGT
ENGIE's Al Ezzel plant in Bahrain is a 950 MW Combined Cycle Gas Turbine facility. During a planned outage, the inspection team deployed Distran cameras to survey four gas units and two steam units — covering turbines, silo burners, heat recovery steam generators, and compressed air systems.
In five days, the team found 77 leaks across all types: 9 methane, 47 compressed air, 12 compensator, and 9 steam leaks. Many had gone unnoticed with conventional tools. The findings were compiled into a prioritized repair report, allowing the maintenance team to address every issue during the same outage window.

Ignite Outage Group — Vacuum Leak Detection During Live Plant Operations
Ignite Outage Group deployed Distran cameras at an 827 MW combined cycle plant in the USA to detect vacuum air ingress into the condenser system — during normal plant operations, with no shutdown required.
Over two days, the team found 26 leaks: 8 vacuum leaks on the Air-Cooled Condensers, 5 on compensators, 2 steam leaks on the low-pressure turbine casing, and 11 compressed air leaks. The previous helium-spray method had been slower, required hot-space entry, and left large areas unchecked.
A separate UK-based CCGT plant case showed that a 7.5 mbar vacuum loss on the condenser system had caused an estimated production loss of 7,862 MWh over six months — equivalent to $1,500,000 USD.
