Ocean currents can spread pipeline leaks, making them difficult for oil spill monitors to spot on the water’s surface.

A 32 hour pipeline leak is not about settled.

A Covington energy company has reached a tentative $3.1 million settlement with the federal government over a 2017 Gulf of Mexico oil leak. The agreement, called a consent decree, was filed in federal court in New Orleans on Wednesday following the filing of a lawsuit earlier in the day. The settlement said the company does not admit to liability for the leak of about 16,000 barrels (about 672,000 gallons) of crude oil from a pipeline about 40 miles southeast of Venice. The suit against LLOG Exploration sought compensation for costs incurred by the National Oceanic and Atmospheric Administration in assessing the damage.

A failed connection led to the spill.

A December 2019 report by the federal Bureau of Safety and Environmental Enforcement attributed the oil spill to a failed connection device, known as a jumper, at an underwater well head. The leak of oil is thought to have begun Oct. 11, 2017 and lasted “at least 32 hours,” according to the lawsuit. The leak wasn’t detected for several hours, according to the report, which included recommendations that the industry improve leak detection methods. The lawsuit doesn’t detail any environmental damage. At the time of the spill in 2017, the Coast Guard said the leaked oil was not expected to reach the shore. LLOG didn’t immediately respond to a request for comment on the lawsuit. There will be a public comment period before the agreement is approved, according to court documents.
