If fire protection is treated as an afterthought in the conversion, you risk a plant where old systems no longer match the hazards and new ones are not ready when gas arrives. That can mean commissioning delay, insurer objections and, in the worst case, a fire or explosion. A planned fire protection upgrade keeps people, plant and output safe through the transition.
USP&E Helps You Protect the Plant Through Conversion
We know you want a conversion that keeps everyone safe and passes inspection the first time. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, and our 400+ engineers and project managers build, convert and operate HFO, diesel and gas-fired plants, with fire protection planned as part of the engineering, not bolted on at the end. Our systems are ISO 9001 and ISO 45001 certified, and every deal runs under FCPA and OFAC controls. USP&E is a full-service EPC and O&M contractor, not a broker.
You do not need to rip out every fire system on day one. You need to understand the new risks, design for them early and keep existing protection live until the HFO plant stops.
Compare HFO Fire Risks with Gas Risks
On an HFO plant, fires usually start when heated fuel or lube oil sprays or drips onto hot exhausts and turbochargers. Oil-soaked lagging, leaking flanges and fuel treatment rooms are the usual weak points. Your existing detection and suppression were chosen for those liquid fuel fires, and your records should show how well they have been tested and maintained.
Gas turbines change the risk. Fuel gas leaks can collect in enclosures and buildings and ignite, so gas detection and ventilation become central. Turbine enclosures hold hot casings, lube oil and fuel lines in a confined space and normally carry their own fire detection and suppression. Gas reception and metering areas create hazardous zones that affect where electrical equipment can be placed.
Write both risk pictures down side by side. That list becomes the basis for design, for the insurer’s review and for the order in which systems are built and retired. The heavy fuel oil fire and handling notes help you recall the liquid fuel risks that stay on site until the last tank is emptied.
Design Detection, Suppression and Fire Water for the New Layout
Plan detection and suppression for each turbine enclosure, the gas reception area, transformers and the control buildings. Enclosure systems are usually specified with the turbine package, so agree early who supplies, installs and tests them, and how they connect to the plant’s fire alarm and shutdown logic. Gas detection should trip fuel and alert operators before a leak becomes a fire.
Check your fire water system against the new layout. Hydrant coverage, pump capacity, water storage and ring main routes were set for the HFO plant. New units, gas areas and transformers may sit outside existing coverage or need more water than the system can supply. Hazardous area classification for gas must be done before cable and equipment routes are fixed.
Our EPC fuel conversion projects handle fire and gas design inside the main engineering scope, so detection, suppression and shutdown logic are coordinated with the turbine package, not added after it.
Keep Protection Live Through the Transition
During conversion, HFO engines often keep running while gas turbine generators are installed nearby. Keep every existing fire system live, inspected and tested until the HFO plant stops for good. Control hot work tightly near fuel tanks and treatment rooms, and update the emergency response plan as new hazards appear on site.
Test the new systems fully before gas is brought on site: detection, suppression release, gas detection trips, fire water and shutdown logic. Whether you install used/new gas turbines, a remanufactured GE Frame 6B or natural gas engines/stations, insurers and authorities will want to see that evidence before first fire.
The same approach applies to AI gas turbines, hyperscale generators and gas turbines for compute delivered under hyperscale EPC/O&M, and to the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA. For the commissioning stage that follows, see our sister site on gas turbine commissioning programmes. If some engines stay in service, review our HFO engine stock.
Where USP&E Supports Your HFO Plant Project
For your HFO-to-gas conversion, your engineering lead sits at USP&E’s Executive HQ in Johannesburg (22 Kildoon Rd, Bryanston), with Cape Town (31 Brickfield Road, Woodstock) adding design, commissioning and project depth. Southern Africa is where USP&E plans, controls and supports frontier power work across the continent.
London (162-168 Regent Street) structures finance and contracts for HFO fuel treatment skids, gas reception trains and remanufactured Frame 6B units, Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) connect you to US equipment supply and US-based engineering, and Wuxi, China (No. 1, Ningzhou Road, Wuxi) follows up China manufacturing and supply chain.
For HFO-to-gas fire protection, Johannesburg and Cape Town engineers can review your current systems, design for the new gas risks and plan the safe changeover. Regions served: USA | AFRICA | UK | UAE | CHINA. Reach matters more than pins on a map: 150+ power projects in 45+ countries, 25,000 MW contracted since 2002, and ISO 9001 and ISO 45001 certified.

FAQ: HFO Plant Fire Protection Upgrade Path to GT
How do fire risks change when an HFO plant moves to gas?
USP&E sees the main risk shift from liquid fuel and lube oil fires on hot engine surfaces to fuel gas leaks that can form explosive clouds. Turbine enclosures, gas reception areas and new hazardous zones all need detection, ventilation and suppression designed for gas.
Do gas turbine enclosures need their own fire suppression?
USP&E normally specifies dedicated detection and suppression inside each turbine enclosure, because hot casings, lube oil and fuel lines share a confined space. Agree early who supplies, installs and tests the system, and how it links to the plant’s fire alarm and shutdown logic.
Will my existing fire water system cover the new units?
USP&E checks hydrant coverage, pump capacity, water storage and ring main routes against the new layout. Systems sized for an HFO plant may not reach new turbines, gas areas and transformers, or may lack the flow they need. That gap must be closed before gas arrives.
How do I keep the plant safe during the conversion?
USP&E keeps every existing fire system live and tested until the HFO plant stops, controls hot work near fuel areas and updates the emergency plan as new hazards appear. New systems are tested fully, including gas detection trips, before any gas is brought on site.
Where are USP&E’s offices for HFO plant conversions?
USP&E leads HFO plant work from Johannesburg and Cape Town, close to many African utility and mining plants. London supports contracts, finance and insurance structuring, Colorado Springs and Knoxville back US gas turbine supply and engineering, and Wuxi follows up switchgear and equipment made in China.
Has USP&E delivered HFO power plants before?
USP&E engineered, supplied and commissioned a 16 MW HFO power station for London Mining at Marampa in Sierra Leone in five months, ahead of schedule. USP&E also delivered a 13.1 MW HFO and diesel modular station for Perenco in Guatemala under full EPC.
Is USP&E a broker for HFO plant upgrades?
USP&E is not a broker. USP&E engineers, builds and operates power plants with its own people, so the team that designs your new fire and gas systems is the same team that installs, tests and answers for them through the conversion.
How fast can USP&E review my plant fire protection?
USP&E can start reviewing your fire system records, test history and conversion layout as soon as you share them. Engineers flag the largest gaps between today’s protection and the new gas risks first, so design and budget focus on what matters most.
Bring Gas On Site with Protection Ready
Plan fire protection early and gas arrives at a plant ready for it. Leave it late and you face delay, insurer objections and real danger. USP&E will help you design, test and convert with confidence.
