Accident Classified As: Reportable Quantity

Cause of Problem: Piping or Tubing

Shell Chemical's GO-1 Process Unit experienced a small pipe leak on a line at the base of a process vessel. The leak developed during an online abrasive blasting job. In order to relieve pressure on this line, operations had to reduce rates at the GO-1 process unit. The reduction of rates caused flaring at Motiva's West Operations Ground Flare (EPN 9-84).

Discharge Preventable - No

The incident was not under the control of Motiva Enterprises, LLC.

Notes/Remedial Actions

Shell Chemical installed a clamp to stop the leak then returned operations to normal conditions.
