An oil spill in the Gulf of Mexico last week may be the largest in the U.S. since the 2010 blowout at BP Plc’s Macondo well that sank the Deepwater Horizon rig.
The Delta House floating production facility about 40 miles (64 kilometers) southeast of Venice, Louisiana, released 7,950 to 9,350 barrels of oil from early Wednesday to Thursday morning, according to closely held operator LLOG Exploration Co. That would make it the largest spill in more than seven years, data from the U.S. Bureau of Safety and Environmental Enforcement show, even though it’s a fraction of the millions of barrels ejected in the 2010 incident.
The LLOG spill was triggered by a fracture in a flowline jumper, Rick Fowler, the company’s vice president for deepwater projects, said in an email. That’s a short pipeline used to connect nearby subsea structures. Multiple barriers placed on either side of the fracture stopped the release, but the the flowline jumper hasn’t yet been repaired, Fowler said.
