Narrative
Probable cause of failure and resulting flange set leak may have been due to movement of the flange set as a result of an adjacent repair on the pipeline. A contributing factor may have been the uneven torqueing of flange bolts at time of initial installation of flange set. As a result, motiva undertook a project to review all flange sets on this pipeline. Where feasible, underground flange sets have now been removed. Above-ground flange sets were inspected. Bolts & gaskets for remaining flange sets have been replaced and the flange sets assembled using the motiva port arthur refinery flange set assembly quality assurance program. This work was completed in early may 2019.
