Pressure Cycle Fatigue Analysis - Pacifica

Featured Image

Pacifica software performs pressure cycle fatigue analysis on crack-like flaws in pipelines based on the advanced PRCI MAT-8 and API 579 Fracture Mechanics methodologies. Fatigue growth analysis is performed using actual pressure data for real-time monitoring. Hydraulic modeling determines true pressure loading at crack locations throughout the pipeline for accurate growth predictions.

Pacifica also uses a database structure to store historical pressure data and line layout information. This helps facilitate faster and more efficient future analysis.

With the support of Quest Integrity engineers, the information gained from the analysis guides prioritization of anomaly investigations, hydrotest and ILI re-inspection schedules, material property testing requirements and evaluation of the impact of operations on seam weld integrity.
