Narrative
A release was discovered by mpl personnel who were on-site for other non-related project work. Approximately 4 ounces of crude oil leaked from between the yoke tube and valve bonnet of roxana station valve ss1 due to a valve packing failure. Mpl personnel attempted to repack the valve but were unsuccessful and therefore, the valve was replaced. The line was later returned to normal operations. Mpl completed its investigation into this release on january 26, 2017. As a result of the investigation, it was determined that a rough finish specification on the valve stem contributed to a quicker than expected deterioration of the valve seals. It was also determined that valve repacking was hindered by a small diameter packing vent which inhibited packing flow. The inhibited flow resulted in a buildup of pressure in the packing box while being repacked which caused the valve stem seals to fail. Part d.8. Was updated to include final costs. Part g.6. Was updated to include investigation results.
