摘要

The field-proven Pipeline Current Mapper (PCM) tech-nique for pipeline External Corrosion Direct Assessment (ECDA) has proven to be effective in determining the con-dition of the coating on buried pipelines of all sizes and services, but data interpretation is more challenging when assessing pipelines buried in congested corridors. IONIK Consulting recently used the PCM technique while operating in a multi-pipeline network environment that impacted data collection and interpretation, requiring a unique solution to achieve accurate desired results. The firm was contracted to perform an assessment of five pipelines at a client's major Southwest chemical facility. The parallel lines were of varying depths and ranged in diameter from 4-16 inches. The operator diligently monitors all of its pipelines using "Best Engineering Practices" and conducts External Corrosion Direct Assessment (ECDA) in accordance with the NACE RP0502-2002 standard.
