Accident Classified As: No Information Given

Cause of Problem: Piping or Tubing

On May 20, at approximately 3:15 PM, a leak was detected from a fuel gas line near the Hydrocracking Unit. A failure analysis conducted on the failed section of the pipe indicated that increased water saturation and chloride content in the stagnant zone of the pipe was the cause of the degradation.

Discharge Preventable - No

The testing conducted on the fittings and turbulent areas at bends, elbows, and tees in the surrounding area of the pipe failure indicated adequate pipe thickness. There were no indications that suggested the piping would fail in that area.

Notes/Remedial Actions

Immediate remedial action was to barricade the area and water was used to dissipate vapors from the release. The line was isolated and a clamp was installed to mitigate the leak. Onsite monitoring was conducted during the events and all results were zero. No emergency conditions or adverse offsite impacts resulted from this release.
