Successful Integrity Test and Remediation of MPOG Pipeline After Oil Spill in Plaquemines Parish

An integrity test was successfully completed on the Main Pass Oil Gathering (MPOG) pipeline system after an oil spill was detected in Plaquemines Parish near New Orleans on November 16, 2023. The test revealed a defective subsea connection on the MPOG line that was not maintaining pressure, but it is unclear if this was the source of the oil spill. Initial estimates suggest around 1.1 million gallons of crude oil may have been released from the 67-mile pipeline, which was shut down by MPOG.

Following the discovery of the faulty connection, MPOG, in collaboration with Unified Command, safely removed and replaced the affected spool section of the pipeline. The operation prioritized safety and environmental protection, successfully completing the replacement on February 21st. Subsequent integrity tests did not identify any additional problem areas, and monitoring measures, including security ships, divers, and cameras, were put in place to prevent further leaks.

The National Transportation Safety Board (NTSB) is leading the investigation into the oil release, with the Unified Command and Pipeline and Hazardous Materials Safety Administration closely monitoring operations. No significant leaks were observed during the replacement process, and the pipeline system was confirmed to be maintaining containment during the tests, ensuring the safety of the environment and community.
