2019 CCJ Best Practices Awards: GE Aeros

The world’s largest independent meeting of aero gas-turbine users attracted more than 1200 owner/operators of LM2500, LM5000, LM6000, and LMS100 engines, and their suppliers and consultants, to the South Point Hotel and Spa. A highlight of the meeting was the sharing of the best practices submitted to WTUI/CCJ by users. Almost certainly one or more identified below might help improve engine performance, help create a safer workplace, and/or reduce cost at your plant.
