Process Historian Integration & Integrity Operating Windows

Connect live process data with integrity limits and engineering action.

AccurAPM Process Historian Integration connects operational process data with asset integrity workflows to provide continuous visibility of Integrity Operating Windows (IoWs). Readings from plant historians and OPC / OPC-UA sources can be mapped to assets and monitored against defined operating limits, helping teams identify excursions, understand their duration and severity, and respond before abnormal conditions contribute to accelerated degradation.

Capabilities

Key capabilities

✓Integration with process historians and OPC / OPC-UA data sources through the AccurAPM integration layer.

✓Mapping of historian tags and operational readings to the asset hierarchy and equipment context.

✓Integrity Operating Windows established and maintained in line with API 584, covering the operating limits and the response required when they are exceeded.

✓Configurable Integrity Operating Windows for pressure, temperature, flow, composition and other integrity-critical variables.

✓Continuous or scheduled monitoring of process values against normal, warning and critical operating limits.

✓Detection and recording of IoW excursions, including start time, duration, severity and affected equipment or corrosion loop.

✓Trend visualization to correlate excursions with inspection, corrosion and integrity information.

✓Dashboards and alerts highlighting active or recurring abnormal operating conditions.

✓Data-quality controls for tag mapping, validation, transformation and exception handling.

Outcomes

Business value

✓Move from periodic review toward continuous awareness of integrity-critical operating conditions.
✓Identify operating excursions earlier and reduce the time between abnormal conditions and engineering response.
✓Connect process behaviour with corrosion, inspection and risk information to support better integrity decisions.
✓Improve traceability by maintaining a history of IoW excursions and their relationship to affected assets.
✓Help prevent accelerated degradation and unplanned integrity events.

How it connects

Connected workflow

Historian and OPC data is ingested through AccurAPM integration services, validated and mapped to the asset hierarchy, then evaluated against configured IoWs. Excursions can be reviewed alongside RBI risk, corrosion loops, IDMS inspection history, anomalies and recommendations.
