ECDA (External Corrosion Direct Assessment) and SCCDA (Stress Corrosion Cracking Direct Assessment) methodologies were developed to assess pipeline integrity and ensure the safe operation of pipelines. The methodologies are applicable to piggable and difficult to pig pipelines. It is critical to precisely identify the direct examination location to ensure the highest return on investment and effective risk mitigation. This paper will present case studies that will summarize the recent advancements and successful application of ECDA and SCCDA methodology on energy pipelines in North America.
