P5 Pipeline ECDA | Audubon Companies |Project Management of Oil and Gas Pipelines
Audubon Companies provided external corrosion direct assessment (ECDA) engineering and technical services to assess pipeline integrity for approximately seven miles of 8” diameter pipeline. The regulated pipeline was subject to integrity management (IM) rules, 49 CFR Part 192, Subpart O. Our team determined that ECDA was an acceptable method to assess the integrity of the pipeline. ECDA was employed to assess pipeline integrity where other assessment methods (in-line inspection, hydrostatic testing) were not feasible or economically viable. Our team provided turnkey services for individual components of the four-step ECDA process including data collection, feasibility analysis, indirect inspection surveys, direct examination digs, and anomaly characterization, data integration, remaining life and reassessment interval calculations and design of repairs.
