Aveva

UOC’s layered visualisation framework dynamically switches between site-wide overview, area, and equipment detail levels based on operator focus without window management, matching operator mental models for faster abnormal situation response. Integration with Aveva PI System historian and Aveva Predictive Analytics surfaces leading indicators and forecast trends alongside live process values in the same screen real estate as traditional SCADA. Alarm management module applies ISA 18.2 rationalisation logic to filter nuisance alarms and present only actionable high-priority alerts, reducing alarm rate by 60-80% in refinery implementations. Aveva InTouch HMI graphic library of 10,000+ process symbols enables rapid migration from legacy DCS operator graphics without redrawn assets. Deployed in integrated operations centres serving multi-site oil and gas, chemical, and mining operations globally.
