Quest Integrity’s Pacifica software performs pressure cycle fatigue analysis of crack-like flaws in pipelines based on state-of-the-art fracture mechanics methodology, including API 579 Part 9 and the newly developed MAT-8 crack failure model. Fatigue crack growth analysis is performed using actual pressure data to enable real-time monitoring, and hydraulic modeling determines correct pressure cycling behavior at crack locations throughout the pipeline, resulting in more accurate growth predictions.
Pacifica also uses a database structure to store pressure data and line layout information for future analysis. The analysis results support the prioritization of anomalies, determination of hydro test and ILI re-inspection intervals, sensitivity analysis, and evaluating the impact of operations on-seam weld integrity.
