If your permits do not change with the plant, people get hurt and machines get damaged. One missed isolation can trigger a fire, an injury or a long forced outage, and the investigation that follows can stop your whole operation and put your contracts at risk.
USP&E as Your Guide to Safe Work on a Changing Fleet
Use your CMMS history to see how diesel consumption actually tracked failures, and apply the same method to the new fleet. Your gas turbine generators need consumables such as inlet filters, igniters and lube oil filters on a schedule, plus insurance spares held against a forced outage.
Treat Permits as Protection for People and Availability
Permits protect people and availability at the same time. A good permit-to-work system defines who can issue, accept and close each permit, which isolations are required, how they are verified and how work is handed over between shifts. It also keeps maintenance from colliding with operations, so a unit is not started while someone is inside it.
Review your current permits against real incidents and near misses. Where crews regularly work around the system, the system is usually too slow or unclear. Simplify where you can, but never remove isolation verification, gas testing or the sign-off that returns plant to service. Audit a sample of closed permits every month, and share what you find with your crews so the system improves instead of becoming paperwork they resent.
Add the New Hazards Gas Turbine Sites Bring
Gas turbine generators introduce high-pressure fuel gas, enclosure fire suppression that can be lethal to anyone inside, hot surfaces, high-speed rotating parts and confined spaces in inlets, exhausts and generators. Each needs specific isolation steps: fuel gas block and bleed, suppression system lockout, rotor locking and atmospheric testing before entry.
Train crews on these steps before the first turbine arrives, not during commissioning. Natural gas engines share some fuel gas hazards, so align their procedures with turbine procedures. Keep one set of lock-out tag-out rules across the site, rather than separate cultures for each type of machine.
Document Frame 6B Bridges and Scale With Your Fleet
A remanufactured GE Frame 6B or used or new gas turbines arriving as bridge units need complete isolation diagrams, valve lists and suppression drawings before your crews touch them. Missing documentation is a hazard in itself, so make it part of the purchase evidence. Walk each isolation point on site against the drawings before the unit is energised, and correct the drawings wherever reality differs.
A remanufactured GE Frame 6B brings many more signals than a genset: vibration, temperatures, combustion data and protection events. It should inherit a working remote-monitoring path, a cleaned tag list and clear alarm priorities, so your service team sees useful information from the first fired start rather than a flood of noise.

Your path from first call to reliable power
Wrong windows produce three failure modes. First, deferred PMs stack until wet-stacking, overheating, or vibration forces a night trip. Second, partial outages open the engine but leave ATS, fuel, or radiator work unfinished — so the plant pays mobilisation twice. Third, production, mine campaigns, or campus exams dictate dates that O&M never saw, so “planned” work becomes renegotiation under panic. Frontier logistics amplify all three: customs, flights, and parts lead times do not compress because the mill suddenly needs power. See spare parts logistics.
- Review the diesel permit book, near-miss records, and which duties will move to gas turbine generators.
- Review equipment in USP&E live inventory and request drawings, isolation points, records, controls status, and logistics dimensions.
- Write the isolation register, turbine permits, training plan, and O&M owners into one Extreme Ownership matrix.
- Complete permits, funding, fuel agreements, and isolation drills before final equipment selection and first energisation.
Common questions
Why do work permits need updating when diesel sites add gas turbines?
USP&E updates permits because gas turbines bring hazards diesel crews may not know: high-pressure fuel gas, enclosure fire suppression, hot sections and confined spaces. Permits written for engines miss those isolations, and one gap can cause injury, fire or a long forced outage.
What isolations are specific to gas turbine work?
USP&E requires fuel gas block and bleed, enclosure fire suppression lockout, rotor locking, electrical isolation and atmospheric testing before entry into inlets, exhausts or generators. Each isolation is verified and recorded on the permit, and the plant is only returned to service through a formal sign-off.
How quickly can USP&E respond to an O&M safety review?
USP&E can start reviewing your permits, incident records and isolation diagrams as soon as you share them. Engineers identify gaps first and prioritise the highest risks, and the rollout timeline then depends on your crew availability, training windows and outage plans.
How should crews train before the first turbine arrives?
USP&E recommends classroom and field training on fuel gas, fire suppression, rotor locking and confined space entry before any turbine reaches site. Crews should walk the isolation points on drawings, then practise on the installed unit before commissioning, so new hazards are understood rather than discovered.
Should engines and turbines share one permit system?
USP&E recommends one permit-to-work system and one set of lock-out tag-out rules across the site. Separate systems for engines and turbines create confusion at shift handover and in shared areas such as fuel gas yards, switchrooms and control rooms, where one crew’s isolation can affect another’s work.
