Integrity Assessment Case Studies of Time-Dependent Threats

摘要

This paper summarizes multiple time-dependent pipeline integrity assessment case studies that were recently conducted on different oil and gas pipelines in North America. Internal, external, and stress corrosion cracking threats were comprehensively assessed considering historical records and several susceptible factors that were specific to each threat. The result of the integrity assessment is an evaluation of susceptible factors of each pipeline based on known and established parameters which affect the likelihood or probability of a corrosion-related event occurring. This paper will substantiate presented arguments using comprehensive case studies discussing susceptible factors of various threats, practical experience and lessons learnt.
