The NACE International Northern Area Western Conference gathers experts to share their knowledge and experience on managing asset integrity and corrosion challenges in the North Western Canadian region, the prairies.
Dynamic Risk’s Vincent Soo will be presenting on Wednesday, February 5th at 1:00 p.m. on “Incorporating inline inspection and cathodic protection data to more effectively evaluate external corrosion for pipelines.”
If you will be attending and would like to meet with one of our team members at the event, please contact Tracey Murray at Tracey_Murray@DynamicRisk.net to arrange a meeting.
External corrosion is a time dependent threat for steel pipelines, which requires continuous prevention and mitigation programs. Magnetic Flux Leakage (MFL) inline inspection (ILI) technology has become a common method to evaluate the integrity of the pipeline. However, ILI provides only a snapshot in time and the integrity of the pipe becomes more uncertain as time progresses, until the next re-inspection. With ILI re-inspections, corrosion growth rates can be estimated by matching metal loss anomalies from the previous ILI to the most recent ILI. Leveraging historic cathodic protection data between inspections, the condition of the pipeline can be assessed more thoroughly during this time period. Extrapolating this data past the most recent inspection enables pipeline operators to assess the effectiveness of the cathodic protection systems in minimizing corrosion growth rates, and better plan remedial activities. This presentation highlights the procedure and various datasets required to more effectively assess external corrosion.
