Oil and gas (O&G) pipelines are expensive assets that cross through both the ecologically sensitive and densely populated urban areas. If not well maintained, pipelines may fail with potentially significant consequences that could have long-term and irreversible impacts on both natural and human environments. The United States Department of Transportation reported more than 10,000 failures in O&G networks across the country which caused losses around six billion US dollars in the form of property damage, production losses, environmental impacts and human casualties. Therefore, to improve the reliability of infrastructure, pipeline failure analysis and inspection is the integral activity. The main components of the pipeline integrity management are: failure identification process of pipelines in high consequence areas; assessment baseline plan; an integrated analysis of defect information and failure consequences of pipeline integrity; criteria for repair actions based on information analysis during assessment plan; a continuous improvement plan of pipeline integrity by assessment and evaluation; preventive and mitigation measures to protect the high consequence areas; programmes effectiveness measurement methodology; a process of information analysis and the review of integrity assessment results; a process of management of change; and a process of record keeping and documentation control.
