Started from the bottom
(World Pipelines, June 2019)


Christophe Baeté, Elsyca nv, Belgium, Len Krissa and Alfonso Garcia, Enbridge Pipelines Inc., Canada, outline the 3D bottom-up approach applied by mechanistic modelling for pipeline integrity management.

Pipeline integrity management software programs (PIMS) generally rely on statistical correlations between big data collected over many years of pipeline operation. However, with respect to corrosion assessment, the ‘devil sits in the details’ and corrosion rates are difficult to monitor directly, which often results in post-mortem assessment by inline inspection (ILI) tools. This is not the case when using mechanistic modelling.
