Anadarko has been partially successful in arguing some of its claims should move forward following the release of 1.1 million gallons of crude oil into the Gulf of Mexico in November 2023.
The lawsuit involving Anadarko Petroleum Corporation and Subsea 7 Marine (US) Inc. centres on complex oil spill litigation proceedings in the U.S. District Court for the Eastern District of Louisiana.
In May 2025, Main Pass Oil Gathering (MPOG) sued subsea engineering firm Subsea 7 alleging that Subsea 7’s defectively designed collet-grip flange connector caused a 1.1-million-gallon crude oil spill in the Gulf of Mexico in November 2023; Anadarko Petroleum Corporation (and its affiliate Anadarko U.S. Offshore, LLC) intervened as a plaintiff in the lawsuit. Anadarko argued that the pipeline leak directly caused it severe economic harm by forcing the shutdown and loss of use of two of its offshore production platforms.
In a recent judgement, a Judge in the US District Court for the Eastern District of Louisiana said the company didn’t meet the requirements of showing it was eligible for recovery costs but it did do enough to preserve other economic damage claims.
