The scope included thorough requirements gathering with ARAMCO stakeholders to ensure alignment with operational goals. EMI developed a standardized symbol library and graphics design methodology to replicate the existing PCS graphics accurately into PI ProcessBook. The graphics replication process accounted for varying complexity levels, ensuring that the displays were both functional and user-friendly. A key technical challenge was the deployment of local PI Servers in each phase, configured with redundant OPC DA interfaces to support high availability and data buffering. EMI configured and buffered up to 10,000 tags across both phases, guaranteeing reliable data flow and synchronization with the corporate PI Server via secure Data Diodes, preserving data integrity and compliance.
Onsite installations, rigorous Site Acceptance Testing (SAT), and comprehensive project documentation—including a Method Statement, Symbol Library, and SAT report—ensured a smooth transition with minimal disruption to operations. The resulting system significantly enhanced control system monitoring and data availability at the Ras Tanura Terminal, supporting ARAMCO’s commitment to operational excellence and system resilience.
