Need: Given the extensive and aging infrastructure of pipelines in developed countries, as well as increasingly stringent regulatory requirements, there is a large incentive to improve damage management processes in order to reduce failures and maintain the existing pipeline infrastructure for a longer period of time. Industry is responding by focusing research and development efforts on key damage management concerns.
Result: The objectives of this report were: to review previous work relating to damage management of onshore gas and liquid transmission pipelines as conducted by PRCI and other organizations: to identify gaps that remain to be filled through research and technological development and to rank the gap elements based on the degree of impediment posed and the potential for elimination in the near term. To carry out the work, a comprehensive literature survey was conducted including a detailed review of relevant documents and reports published by PRCI, GRI and other industry consortia. From this information, current capabilities with respect to the detection and sizing of damage, the prediction of defect growth, the assessment of remaining resistance capacity, and the mitigation and/or repair of damage were characterized for each damage mechanism. Available methods, models and tools were evaluated and any elements that are missing or that could be improved were identified. Missing or deficient elements of the damage management process were then evaluated and ranked.
Benefit: This report describes the results of a project to identify and prioritize gaps related to the detection and management of existing damage. The main emphasis of the study was on damage management of onshore gas and liquid transmission lines. Damage mechanisms considered include external corrosion, internal corrosion, fatigue growth of crack-like seam-weld defects, stress corrosion cracking (SCC), mechanical damage and ground movement.
