The U.S. Coast Guard has partially assumed federal control over the operation to contain an oil dishcarge from the site of MC20 platform in the U.S. Gulf of Mexico that has likely been leaking since the platform toppled back in 2004.
The platform, owned by Taylor Energy, LLC, was located in Mississippi Canyon Block 20, approximately 11 miles south of the mouth of the Mississippi River. It toppled in September 2004 during Hurricane Ivan after storm surge triggered an underwater mudslide. The incident left the platform well conductor pipes buried in more than 100 feet of mud and sediment, impacting 25 of 28 connected wells. The spill went unnoticed for years until 2008 when it was identified as the source of daily sheen reports.
Now more fourteen years after the hurricane, crude oil continues to discharge from the site and surface on the Gulf waters.
IN 2015, the U.S. Bureau of Safety and Environmental Enforcement estimated that oil continues to leak at a rate of approximately 1 to 55 barrels of oil per day. Satellite imagery and overflights have shown oil slicks on the surface varying in size, sometimes ranging up to 30 miles in length.
Even still, the specific source, or sources of the discharge at the MC20 site are not fully known.
Federal officials have directed Taylor Energy, as the Responsible Party, to remove the platform deck, remove sub-sea debris, decommission the oil pipeline, attempt to contain the leaking oil, and plug nine of the 25 impacted wells that were deemed highest risk....
