7FUG 2025: First-time users reap a wealth of experience from veterans

Among the portfolio of conferences under the umbrella of Power Users, the 2025 7F Users Conference certainly vies for the one with the most content shared directly from owner/operator (O/O) organization representatives. Which makes it especially valuable for the ~50% of attendees who were first timers. One key take-home tidbit: Most, if not all, of

7FUG 2025: Aftermarket suppliers target fleet life extension

The 7F Users Group’s 2025 vendor and solutions-provider program highlighted how much of the reliability discussion now extends beyond the gas turbine itself. Presentations covered rotor life extension, compressor stator-vane looseness, generator inspection and hydrogen-purge safety, controls calibration, intake filtration, lube-oil varnish, leak detection, coupling-bolt replacement, and owner’s-engineer support. Together, the sessions gave users a

Maximizing the lifespan of CO catalyst: What operators should check before ordering replacement

For many gas-turbine users, CO-catalyst trouble shows up first as a compliance headache: stack CO starts climbing at low load, differential pressure changes, and the plant is forced to decide whether it is looking at a cleaning issue, a system issue, or end-of-life catalyst. That decision now carries more economic weight than it did a

HV ELECTRICAL: Closing the inspection gap on switchyard high-voltage assets

Tip: Implement a structured visual inspection program for switchyard high-voltage equipment between scheduled maintenance intervals, supported by periodic thermal and acoustic diagnostics, to catch early indicators before they become forced outages. Bryan Miller of RATTLIR LLC recently called CCJ editorial offices to flag something he keeps seeing at gas turbine sites: a significant gap between
