The Unified Command completed a line integrity test on the Main Pass Oil Gathering (MPOG) company's pipeline system near Plaquemines Parish, southeast of New Orleans, the U.S. Coast Guard said on April 8.

"Following a successful line integrity test of the MPOG line, the Unified Command has stood down its work to respond to the oil release observed on November 16," they added.

A line integrity test confirms that all points are leak-free.

In November 2023, an oil spill was reported near the Main Pass Oil Gathering Co.'s pipeline system in the Gulf of Mexico.

A failed subsea connector was identified on the MPOG line that did not hold pressure during the integrity test and was successfully replaced on Feb. 21, the Coast Guard said in the statement.

As per the release, the integrity test completed on April 5 did not identify any other segments requiring further assessment as the line was able to maintain pressure.

The Unified Command did not confirm whether the connector was related to the Nov. 16 release.
