Louis Dreyfus Commodities operates an ethanol plant in Norfolk, Nebraska. The plant needed a new operating system, but could not afford to lose any production time. Trident worked with plant managers to design a system and process that could be installed during a scheduled 3-day outage.
For 12 weeks, teams did pre-engineering work in Wisconsin with installation designed to take hours instead of days. On site, engineers removed an APACS DCS, then installed a customized cabling system to use existing field terminations. The entire system was programmed on PCS 7. During installation, critical control was regained in four hours and the plant never felt the full impact of any downtime.
