Integrated automation and electrical control systems are vital for project optimization, system simplicity and operational flexibility in electro-intensive O&G plants. Value of integrated systems through the life-cycle of the plant from design & engineering to construction and operation is widely understood as having a positive impact on CAPEX and OPEX as well as the reliability of operations. Digital twins of the plant and the process hold key information to maximize operational profitability and optimize asset performance. Next generation of digital-ready integrated process and power management system architectures enables digital performance management of plant-wide assets and processes. An evolving approach is the integration of power and process systems throughout the lifecycle of the plant, commencing at the plant design phase and progressing to the operational stage. The improved operational efficiency brought up by integrated power and process control systems through greater situational awareness, improved reliability, and faster troubleshooting extends the value of this integrated approach to operations & maintenance lifecycle. The comprehensive approach to power and process integration is achieved through seven value driven strategies that spans the lifecycle of a process plant.
