GE Distributed Power (GE) has announced the latest enhancement to its Waukesha 275GL+ lean-burn gas engines, the 275GL+ with ESM2. With a current lead time of less than 20 weeks, this new generation provides a high-performance and economical alternative for customers in the oil and gas midstream industry with compression needs for gathering, processing and transportation applications. The announcement was made at GMRC’s (Gas Machinery Research Council) Gas Machinery Conference, being held 30 September - 3 October in Kansas City.

Waukesha 275GL+ gas engines are offered in a 16-cylinder model, rated at 5000 bhp, and a 12-cylinder model, rated at 3750 bhp. This latest generation of the 275GL+ represents a significant enhancement for the largest Waukesha gas compression engine platform.

“We focused our priorities on improving fuel flexibility, altitude capability and lowering NOx emissions for this latest generation of the Waukesha 275GL+ gas engine family. A low compression ratio piston design coupled with larger turbochargers and the latest ESM2 engine controller for Waukesha gas engines were instrumental in getting us these improvements,” said Dr. Andreas Lippert, General Manager Product Management at GE’s Distributed Power business.

The latest 275GL+ engine achieves 0.3 g/bhp (140 mg/Nm3) NOx emissions levels while maintaining flexibility to offer full power up to 1550 Btu/ft3 (58 MJ/ Nm3) and at altitudes up to 6000 ft (1829 m).

The 275GL+ now also comes with ESM2, the next-generation Waukesha gas engine controller and full-colour touchscreen customer interface HMI panel available in 12 in., 15 in. or 19 in. screens. The advanced control system allows users to see all engine parameters, trend data, monitor faults, view operating manuals, walk through troubleshooting steps, display alarms and set shutdown criteria, and simplify start-up and commissioning – all without the need for a separate laptop computer. ESM2 also helps enhance performance by improving ignition timing based on fuel quality to increase power, fuel flexibility and altitude capability. In addition, ESM2 incorporates GE’s myPlant Asset Performance Management solution that enables operators and service providers to remotely monitor equipment health, diagnose faults and to proactively manage asset performance.

“With the midstream industry experiencing rising costs and long lead times on critical equipment, finding cost-effective ways to gather, process and move as much gas as possible in a timely manner to meet our customers’ investment return criteria is critical,” added Lippert.

The new generation of the Waukesha 275GL+ gas engine with ESM2 will be available for quoting in early 2019.
