AED lead the replacement of old Modicon and Provox hardware with a new DeltaV process control system during a three-week turnaround for a chemical plant in Texas. AED provided design oversight, turnaround planning, and construction management services for the replacement affecting over 1200 loops, which included a concurrent reactor replacement. Installation execution and loop checking were completed over a four-day period ahead of schedule. The team faced many construction challenges, most notably the rescheduling of the outage and workspace constraints in the electrical rooms due to Hurricane Florence.
