Probabilistic safety evaluation of the effective area methods for the assessment of crack and corrosion defects in pipelines

Pipeline integrity management involves effectively managing various threats, including cracking and corrosion. Crack and corrosion threat management has evolved keeping pace with advancements in the Inline Inspection (ILI) technologies which are primary tools for detection and sizing of crack and corrosion features on a pipeline. With the high-resolution inspection data obtained through ILI tools, the ILI vendors can report features’ profiles with varying depths along the length of crack and corrosion features. Compared to the past, when features were reported with a single maximum depth value that was assumed for the full length, the pipeline operators conservatively assumed the maximum feature’s depth in their assessment analysis. The goal from this research project is to develop an approach to utilize features’ profiles in the reliability analysis of crack and corrosion threats.
