Project summary

An offshore platform operator in the Gulf of Mexico enlisted Audubon’s automation and control team to upgrade the existing facility’s programmable logic controller (PLC), safety instrumented system (SIS), and human-machine interface (HMI) systems. The scope of work included project management, procurement, programming, graphics development, testing, and onsite deployment. A detailed online SIS and basic process control system (BPCS) cutover procedure was also developed and tested before implementation to eliminate facility downtime.
