Accident Classified As: Reportable Quantity
On December 2, 2012, Shell Chemical's OL-5 Process Unit experienced an unexpected leak of the Core Exchanger, which led to flaring at the OL-5 Elevated Flare to isolate the leaking exchanger, repair, and return it to service. The release began on December 2, 2012 at 6:15 AM and ended on December 6, 2012 at 11:55 PM. Repairs were made to the core exchanger and the unit was safely returned to normal operations conditions.
The leak in the core exchanger was unpredictable.
The unit was secured and adjustments made to minimize flaring. Preparations were begun to complete repairs to the core exchanger. The flaring was stopped once the repairs were completed and the OL-5 process unit was safely restored to normal conditions. To prevent recurrence, maintenance practices were reviewed and improvements were made. Entire PDF report was not able to be uploaded. Contact LABB for the full report.
