Waukesha, Wisconsin, May 16, 2023 — INNIO’s Waukesha mobileFLEX engine portfolio, comprised of engines and generator sets (gensets), now features advanced ESM2 controls and an enhanced piston to reduce the emissions and operating costs of oilfield equipment and drill rigs significantly.

A natural gas alternative to diesel units, the EPA mobile-certified Waukesha mobileFLEX engines and gensets operate on a range of field gases without derate. Waukesha mobileFLEX products are flexible in a variety of altitude and temperature applications and provide exceptional transient performance with diesel-like load capacity, handling up to 65% load steps and 100% load shed. Drilling operators and contractors will benefit from both the ability to put more power on site as well as reduced nitrogen oxides and greenhouse gas emissions.

Better performance and engine uptime with ESM2: Maximizing engine performance and uptime, the Engine System Manager (ESM2) with AFR2 controls is an easy-to-use system that allows users to see all engine parameters and trend data, as well as view manuals and service bulletins. Additionally, data analytics enhance controls and performance improvements while giving users total control – all without the need for a laptop computer.

New piston design reduces emissions: The optimized piston reduces emissions of regulated pollutants such as carbon monoxide, volatile organic compounds, and formaldehyde. While the new technology reduces operating costs, support technicians will not need to retrain because of its similarity to existing components.

These improvements will exceed operator and contractor expectations. The new controls and piston enhancements have been specifically designed to deliver the level of engine performance required by drilling applications. Our vision is that operators and contractors, when using 100% natural gas, can achieve the same engine performance they’d expect from a diesel engine while saving on fuel costs and lowering emissions.

Jason Padilla, vice president of Product Management and Marketing for INNIO’s Waukesha brand.

Performance confirmed: Waukesha engines running on 100% field gas from producing wells are providing power for drilling rigs in West Virginia while offsetting 2,000 gallons of diesel fuel per day. The switch to mobileFLEX engines is estimated to cut emissions of nitrogen oxides and particulate matter by more than 99%, carbon monoxide by 34%, and carbon dioxide by 7%. Additionally, reducing truck staff has eliminated approximately 200 diesel fuel deliveries.[1]
