The Bearing, Roller, Cylindrical No. 6R is a precision-engineered component used in LM2500 aero-derivative gas turbines commonly employed in the oil and gas sector. Installed at the No. 6R position, this cylindrical roller bearing supports the turbine’s rotor shaft by carrying radial loads and maintaining accurate shaft alignment during high-speed operation.

Its specialized roller design allows it to withstand intense mechanical stresses and thermal changes typical in demanding oil and gas environments. By reducing vibration and ensuring smooth rotation, the bearing contributes to stable and efficient turbine performance, which is critical for continuous operation in upstream, midstream, and downstream applications.

The No. 6R bearing’s role in maintaining precise shaft positioning supports the overall durability and reliability of LM2500 turbines used in gas compression, power generation, and offshore platforms, making it a key element in sustaining safe and efficient operations within the oil and gas industry.

The 2-cup Fuel Nozzle is a precision-engineered component used in gas turbines, specifically in the oil and gas industry. Its primary function is to inject liquid fuel into the combustion chamber in a fine, atomized spray, allowing for optimal mixing with air and efficient ignition. This ensures stable combustion, better fuel efficiency, and reduced emissions—key performance factors in industrial turbine applications.

The “2-cup” design refers to the nozzle’s dual flow passages, which help balance fuel distribution across the combustion zone. This promotes more uniform flame stability and lowers the risk of hot spots that can cause thermal stress to the turbine hardware. The nozzle is typically used on “base” engines and is suited for continuous-duty operations.

The L47197P05 variant is known for its compatibility with LM2500 turbine configurations and is built to endure harsh operating environments. It features durable materials and a design that withstands high temperatures and pressures commonly found in oil and gas turbine systems.

The Single Annular Combustor (SAC) version of the LM2500+G4 is designed for oil and gas applications that prioritize consistent performance, fuel flexibility, and emissions control—such as LNG facilities, gas processing plants, and pipeline compression, both onshore and offshore.

What makes the SAC version different is its simpler combustor design compared to dual annular or premix types. The SAC uses a through-flow, venturi swirler to ensure an even temperature profile at the turbine inlet, helping extend hot section life. It features individually replaceable fuel nozzles, a durable machined-ring liner, and a thermal barrier coating for better resistance to high temperatures and corrosion. This design supports both dry operation (with higher emissions) and water or steam injection to reduce NOx when needed—making it adaptable to site-specific emission regulations.

The LM2500+G4 SAC builds on the proven LM2500+ design, with approximately 10% more power. This gain comes from increased airflow, improved internal cooling, and material upgrades—while keeping the same number of compressor and turbine stages. The 17-stage high-pressure axial compressor and the basic engine layout remain unchanged, making it easy to maintain and service.

The engine can run on a wide range of liquid and gas fuels, allowing flexibility in remote or supply-constrained locations. It achieves up to 40% thermal efficiency in simple cycle mode. Water-injected operation enables NOx emissions as low as 25 ppm (gas) and 42 ppm (liquid).

In short, the LM2500+G4 SAC is well-suited for high-power mechanical drive and power generation in harsh or remote oil and gas environments, offering a balance of power output, fuel versatility, and emissions control.

The LM2500XPRESS+G4 DLE UPT is a fast-deployable gas turbine system engineered for demanding oil and gas environments—onshore or offshore. It offers a balanced combination of power, efficiency, and installation speed, making it especially suited for upstream, midstream, and LNG operations where reliable electricity and mechanical drive are critical and timelines are tight.

At the core of this system is the LM2500+G4 gas generator, a proven design that delivers higher output and efficiency than earlier models, thanks to improvements in airflow, thermal capability, and cooling. It strikes a solid middle ground in the 20–40 MW class—powerful enough to support heavy oilfield infrastructure but lighter and more flexible than larger industrial turbines.

The Dry Low Emissions (DLE) combustion system helps meet environmental regulations without relying on water or steam injection—a major advantage for remote or offshore sites where water supply is limited or emissions compliance is strict.

The Upgraded Power Turbine (UPT) adds flexibility in terms of shaft speed and load-following, which makes this unit adaptable for various oil and gas power demands—from continuous baseload operation to backup and peaking support.

Its XPRESS configuration emphasizes rapid deployment. The turbine is delivered in a compact, modular format, pre-assembled into a small number of transportable units with simplified electrical and mechanical interconnections. This minimizes site work, shortens commissioning time to a matter of weeks, and reduces exposure to remote-site construction risks.
