Narrative
On july 18, 2018, marathon pipe line's (mpl) operations center received a hazardous atmosphere alarm at 16:42, while switching from robinson unit 5 to unit 3. Mpl field personnel confirmed an active leak at the flanged connection for the heat exchanger. Approximately seven gallons of diesel was released. All product was contained on-site and cleaned up promptly. The cause of the gasket failure was due to an overpressure of the heat exchanger while switching units. Piping design and inadequate procedures contributed to the overpressure of the heat exchanger. Procedure updates have been implemented to prevent starting unit 3 before unit 5 is shutdown and an engineered solution is being developed to improve piping design. 10/19/18 update: updated narrative with investigation results.
