Multi-Mechanism Approach to Modeling Corrosion Threats to Pipelines

June 2017, Vol. 244, No. 6

By Joe Pikas and David Richardson, Technical Toolboxes Consulting Ltd., Houston

An innovative, common-sense strategy has been established to show the integrity hazard of pipelines attributed to internal corrosion deterioration mechanisms. The methodology provides guidelines for scheduling mitigation actions to prevent new corrosion, bringing any pre-existing corrosion damage to a standstill. The threat-assessment method comes from basic, data-heavy approaches as it adopts use of “big-data” predictive analytical algorithms to classify pipelines according to established threats. Pipeline failures attributed to internal corrosion occur with increasing frequency each year throughout North America in both the upstream (oil and gas production) and the downstream (natural gas and liquids transportation)…
