Narrative
Nustar operating personnel discovered a crude oil release at a 16-inch flange near tank 400m-3, inside nustar's corpus christi north beach crude terminal. The cause of the accident was over-pressure due to thermal stress on the isolated pipe segment, and the release occurred inside of secondary containment. Failure to adhere to an alignment procedure contributed to the accident. The thermal relief system for the terminal pipe segment was undergoing maintenance during the release, and has since been restored. The gasket within the 16-inch flange has been replaced.
