If your lockout procedure does not cover every one of those sources, someone will eventually open a machine that is not truly dead. The result can be a serious injury, a fire or an incident investigation that stops work across the whole site. That risk sits with you and with every person you send to work on the plant.
USP&E Helps You Carry Lockout Discipline From Cat-Class Sets to GT
USP&E is not a Caterpillar dealer, but we have worked on many sites where reciprocating fleets and turbines share people, switchgear and permits. With 150+ power projects in 45+ countries and 25,000 MW contracted since 2002, USP&E puts 400+ engineers and project managers behind you; they map energy sources, write isolation procedures and train crews so gas turbine generators and existing sets can be worked on safely side by side. You get ISO 9001 and ISO 45001 certified quality and safety systems, with FCPA and OFAC compliance on every contract. USP&E is a full-service EPC and O&M contractor, not a broker.
Good isolation is not paperwork for its own sake. It is the system that lets your technicians open a machine knowing it cannot start, pressurise or energise while their hands are inside it.
Map Every Energy Source on Your Existing Fleet
Start with the machines you already have. For each Cat-class set, list every energy source: the generator breaker and any back-feed, control power, starting batteries or air receivers, the fuel supply, coolant and exhaust heat, and stored pressure in lube and fuel lines. You may find sources your procedures never mentioned, such as space heaters or battery chargers fed from a separate board.
Mark each isolation point on the site drawings and on the equipment itself with durable labels. A technician should never have to guess which valve or breaker isolates which machine. Where one breaker or valve serves more than one unit, write that down clearly.
Then write a lockout procedure per unit. It should give the order of isolation, the lock and tag points, and the proof test that confirms the machine is dead before work begins. Testing for absence of voltage and bleeding stored pressure are steps, not suggestions.
Add the Energy Sources Turbines Bring
A gas turbine package brings new hazards. Fuel gas lines run at higher pressure than most diesel systems, and gas can collect in an enclosure. Lube oil stays hot long after shutdown. Hydraulic and pneumatic actuators can move valves, and carbon dioxide or other fire suppression systems can discharge into an occupied enclosure if they are not isolated first.
Add each of these to the procedure, with its own isolation and proof step. Ask the turbine supplier for their isolation guidance and fold it into one site system rather than running two separate rule books. Crews who move between machines should follow one permit process.
Shared switchgear needs special care. When Cat-class sets and turbines feed the same bus, a breaker racked out for one machine may not isolate the cable a technician is about to touch. Single-line diagrams and switching schedules must be accurate and current.
Train, Audit and Keep the System Alive
Train every crew member and contractor on the combined procedure before turbine work starts, and repeat the training when equipment changes. Practical walk-downs at the machine work better than classroom slides, because people learn where the isolation points really are.
Audit live permits and lockouts on site. Check that locks are on the right points, that proof tests were done and recorded, and that permits are closed properly when work ends. Each gap you find in an audit is an incident you have prevented, and each fix you make shows your crews that you take their safety seriously.
The same discipline scales up. On compute campuses delivered through hyperscale EPC/O&M, AI gas turbines, hyperscale generators and gas turbines for compute share switchgear and fuel systems across many blocks, so the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA is planned with clear isolation points per block. Whether you add a remanufactured GE Frame 6B, verified used/new gas turbines or natural gas engines/stations, isolation belongs in the design.
USP&E Offices Serving Cat-Class Power Buyers
Southern Africa is home base. USP&E’s Executive HQ in Johannesburg (22 Kildoon Rd, Bryanston) owns engineering, procurement and project controls for your Cat-class fuel train upgrade, and Cape Town (31 Brickfield Road, Woodstock) backs it with design and commissioning support.
Equipment and finance for Cat-class gensets, fuel skids and gas turbine packages draw on the wider network: London (162-168 Regent Street) supports structuring and finance, Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) link you to US supply and engineering, and Wuxi, China (No. 1, Ningzhou Road, Wuxi) covers China sourcing and manufacturing.
For Cat-class sites adding turbines, Johannesburg and Cape Town engineers can walk your fleet with your supervisors, mark every isolation point and help merge reciprocating and turbine procedures into one permit system. Regions served: USA | AFRICA | UK | UAE | CHINA. Across 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, USP&E is ISO 9001 and ISO 45001 certified.
Proof from Recent Cat-Class Power Projects
You want proof that USP&E has delivered and maintained power stations where Cat-class engines and new equipment had to be worked on safely together. These projects show that record.
- USP&E supplied 28 Cummins KTA50 containerised diesel gensets, 1,275 kVA each, for Perseus Mining’s Nyanzaga Gold Project in Tanzania.
- Barrick Gold, Loulo-Gounkoto, Mali: USP&E rebuilt more than 80 MW of Caterpillar CM32 engines and added 24 MW of new zero-hour capacity, delivering a 104 MW station with 300% greater reliability and availability than previously recorded at site. Read the case study.
- Mining O&M recovery, Mali: USP&E took over a 100+ MW plant of 15 Cat CM32 engines left in critical condition, restored availability to about 95% and cut maintenance and repair cost per engine by 66%. Read the case study.
HowTo: Carry Cat-Class Lockout Discipline into GT
Your 3-step plan: 1. Share your current lockout procedures, drawings and turbine package data under NDA. 2. Receive an energy source map, isolation points and a combined procedure. 3. Train, audit and keep isolation discipline under accountable O&M.
- List every energy source on each Cat-class set: electrical, fuel, starting air or batteries, stored heat and pressure.
- Mark each isolation point on site drawings and on the equipment itself.
- Write a lockout procedure per unit with the order of isolation and the proof test.
- Add gas turbine energy sources such as fuel gas, lube oil, hydraulic and fire suppression systems.
- Train crews and contractors on the combined procedure and the permit system.
- Audit live permits and lockouts on site and fix gaps before they become incidents.

FAQ: Cat-Class Isolation and Lockout Path to GT
Is USP&E a Caterpillar dealer?
USP&E is not a Caterpillar dealer. USP&E is a full-service EPC and O&M contractor that helps you run safe isolation across Cat-class sets and gas turbines on the same site, with one accountable team for procedures, installation and the maintenance that follows.
What energy sources do turbines add to a lockout procedure?
USP&E adds fuel gas at pressure, hot lube oil, hydraulic and pneumatic actuators, fire suppression systems and shared switchgear to your procedure. Each one needs its own isolation point and proof step, so crews can confirm the package is truly safe before they open it.
Why is shared switchgear a lockout risk?
USP&E treats shared switchgear as a common gap. When several machines feed one bus, a breaker isolated for one unit may not isolate the cable or panel a technician is about to touch. Accurate single-line diagrams and switching schedules close that gap.
Should Cat-class sets and turbines use separate permit systems?
USP&E recommends one site permit system covering every machine. Crews move between reciprocating sets and turbines, and two rule books create confusion. Fold supplier isolation guidance into one procedure that your whole team uses, and train every crew member and contractor on it before turbine work begins on your site.
Where are USP&E’s offices that support Cat-class sites?
USP&E supports Cat-class sites from Johannesburg and Cape Town, where O&M and safety engineers can reach you quickly. London structures contracts and finance, Colorado Springs and Knoxville support turbine supply and engineering, and Wuxi follows up switchgear and enclosures made in China.
Has USP&E delivered power projects beside Cat-class fleets?
USP&E supplied 28 Cummins KTA50 containerised diesel gensets, 1,275 kVA each, for Perseus Mining’s Nyanzaga Gold Project in Tanzania. Public case studies also cover Resolute’s Syama mine in Mali, where USP&E supplied, installed and operated a Caterpillar power station. You can read each case study yourself.
Is USP&E a broker for turbines or safety services?
USP&E is not a broker. USP&E designs, builds and maintains power plants with its own engineers and technicians, so the people who write your isolation procedures are the same people who follow them on site and answer for safety during operation.
How fast can USP&E respond to a lockout review?
USP&E can start reviewing your procedures, drawings and permit records as soon as you share them under NDA. Engineers flag missing energy sources and unmarked isolation points first, then plan a site walk-down timed around your crews and outage plans.
Send Every Crew Home Safe
Isolate every energy source and your crews open turbines and engines knowing they are truly dead. Leave gaps and one missed valve or breaker can cause an injury and stop the site. USP&E will help you map, train and audit isolation with confidence.
