Plan it badly and the risks are high: an outage that runs weeks over, a crane that arrives late, parts stuck at customs, a crew waiting for tools, a mine or town without enough power, and a unit that returns to service with problems nobody had time to fix. That means lost output, penalties and a bill far above budget.
USP&E Helps You Plan the Overhaul Before the Unit Stops
We know you need the overhaul done right and done on time, far from the support most guides assume. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, and our engineers and project managers maintain, refurbish and overhaul gas turbines and engine plants across Africa and beyond. Our systems are ISO 9001 and ISO 45001 certified. USP&E is a full-service EPC and O&M contractor, not a broker.
You do not need to accept a long, uncertain outage. You need a firm scope, early decisions on repair or exchange, parts and tools on site before the unit stops, cover power for the gap, and one team accountable from shutdown to restart.
Confirm the Scope and Make Early Decisions
Start by confirming that the major overhaul is due. Check fired hours, starts, trips and the findings of the last combustion and hot gas path inspections. Borescope results and trends in vibration, exhaust temperature spread and output tell you how hard the unit has worked and what you are likely to find when you open it.
Agree the scope in writing. A major overhaul usually covers the compressor, combustion system, hot gas path, bearings and seals, and often generator and auxiliary checks too. Decide early whether major parts will be repaired during the outage or replaced with exchange modules, because that choice drives outage length, cost and logistics.
Make these decisions months ahead, not weeks. Parts with long lead times, such as hot section components, need to be ordered early. Your service terms matter here, and a clear view of how turbine service agreements work helps you see what is covered and what is not.
Get Parts, Tools and People to Site First
Remote sites need a logistics plan as detailed as the technical plan. List every part, consumable, special tool and lifting device, and plan how each will reach site: by sea, air or road, through which border, with what paperwork. Allow time for customs and for road conditions in the rainy season. Our sister site covers mine power station work in Africa where these routes are common.
Book cranes, lifting gear and specialist tools well ahead, and check that they suit your site’s ground conditions and access. Plan crew travel, visas, accommodation, food and medical support. A crew that arrives before its tools, or tools that arrive without the people who know how to use them, wastes days of outage time.
Stage everything on site before the unit stops. Check that every crate has arrived, that nothing is damaged and that tools are calibrated. Prepare laydown areas, clean work zones and weather protection. Many parts can be sent for zero-hour refurbishment while exchange modules keep the outage short.
Run the Outage and Restart with Confidence
Protect your site’s power during the outage. Plan which units carry the load, what non-critical loads can be shed and whether you need bridge power while a unit is down. Agree the plan with the people who depend on the power, whether that is a mine, a factory or a town.
During the overhaul, record every finding with photos and measurements. Hold daily progress meetings, track the critical path and decide quickly when a finding needs extra work. After the rebuild, test the unit step by step: rotation checks, controls, a first fire, then load tests. File a full report and update your maintenance plan with what you found.
Major overhauls are where good service networks prove their worth. Fleets that run gas turbine generators, used/new gas turbines, a remanufactured GE Frame 6B or natural gas engines/stations all need this discipline. Teams doing hyperscale EPC/O&M work plan the same way for AI gas turbines, hyperscale generators and gas turbines for compute, including the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA.
USP&E Teams Behind Your African O&M Site
Remote sites need people who know frontier work. USP&E runs your Frame 6B O&M network in Africa from Johannesburg (22 Kildoon Rd, Bryanston) and Cape Town (31 Brickfield Road, Woodstock), where engineers plan mobilisation, spares and site supervision for projects far from the nearest service shop.
Further back in the chain, London (162-168 Regent Street) handles financing and contract structure for Frame 6B spares, field tooling and service crews; Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) secure US equipment, parts and engineering support; and Wuxi, China (No. 1, Ningzhou Road, Wuxi) keeps Chinese-made switchgear and balance-of-plant moving.
For remote overhauls, Johannesburg and Cape Town engineers plan logistics, crews and cover power with your site team, while Wuxi supports parts and tooling sourced from China. Regions served: USA | AFRICA | UK | UAE | CHINA. That team has carried 150+ power projects in 45+ countries and 25,000 MW contracted since 2002, ISO 9001 and ISO 45001 certified.
USP&E Track Record for African O&M
You want proof that USP&E can maintain and refurbish turbine and engine fleets in tough places. These projects show that record.
- USP&E supplied 28 Cummins KTA50 containerised diesel gensets, 1,275 kVA each, for a gold project in Tanzania.
- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- A gold mine in 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.

FAQ: Africa GT Major Overhaul Support Network
What does a gas turbine major overhaul cover?
USP&E scopes major overhauls to cover the compressor, combustion system, hot gas path, bearings and seals, often with generator and auxiliary checks. The exact scope depends on the unit’s hours, starts and earlier inspection findings, and it is agreed in writing before parts are ordered.
Should parts be repaired or exchanged during an overhaul?
USP&E weighs repair against exchange modules early, because the choice drives outage length, cost and logistics. Exchange modules usually shorten the outage, while repair can lower cost if time allows. The decision is made months ahead so long-lead parts arrive in time.
How can a remote site keep its overhaul on schedule?
USP&E keeps remote overhauls on schedule by staging every part, tool and crane on site before the unit stops. A detailed logistics plan covers shipping routes, customs, road conditions, crew travel and accommodation, so the outage starts with everything ready.
How is site power protected during a major overhaul?
USP&E plans cover power with your site team before the outage. Options include running other units harder, shedding non-critical loads and bringing in temporary or bridge power. The plan is agreed with everyone who depends on the supply, with clear limits and a way back.
Where are USP&E’s offices for African gas turbine service?
USP&E supports gas turbine service in Africa from Johannesburg and Cape Town, with engineers and crews who travel to remote sites. London supports contracts and finance, Knoxville and Colorado Springs back engineering and US parts, and Wuxi supports parts and tooling sourced from China.
Has USP&E delivered turbine and plant maintenance before?
USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers. Public case studies also include a gold mine power station in Mali, where Caterpillar engines were rebuilt and new zero-hour capacity was added to lift reliability.
Is USP&E a broker for gas turbine overhauls?
USP&E is not a broker. USP&E plans and carries out overhauls with its own engineers and crews, so the team that scopes the work and moves the parts is the same team that rebuilds the unit, tests it and stays accountable for the result.
How fast can USP&E plan a major overhaul?
USP&E can review your unit records, inspection reports and site details as soon as you share them. Engineers flag long-lead parts and logistics risks first, so you can order early and set an outage date that your site and your crew can both meet.
Overhaul on Time, Far from Anywhere
Plan the overhaul early and your unit returns to service on schedule, even at the most remote site. Leave it late and every missing part adds days of lost power. USP&E will help you scope, stage and restart with confidence.
