Remotely Operated Vehicle footage of riser pipe and debris field in the Mississippi Canyon block 252, collected Oct. 4-5, 2011

Following are links to Remotely Operated Vehicle (ROV) video footage, collected by Transocean, of the riser pipe and debris field in the Mississippi Canyon block 252 in response to the Notice of Federal Interest issued by the U.S. Coast Guard, Sept. 27, 2011.

A series of sheen sightings in the area of Mississippi Canyon block 252 had indicated the possibility of a release from the riser pipe or other debris on the ocean floor from the April 20, 2010, Deepwater Horizon explosion and eventual sinking. However, further inspection of the wreckage site has indicated that this is not the case.

An ROV was deployed Oct. 4-5, 2011, and the footage was monitored by U.S. Coast Guard. These visual inspections indicated that there is no release of oil from the riser, the fuel tanks or any other debris at the wreckage site and no discharge or leaking from the riser or the wreckage was observed. Furthermore, there was no oil product either on the surface or subsurface that could be sampled.

The Macondo 252 well was capped on July 15, 2010, and permanently killed by sealing the well and annulus with cement on Sept. 19, 2010. The well was later plugged and abandoned with the approval and oversight of the Gulf Coast Incident Management Team Unified Command. Recent ROV footage of the capped Macondo 252 well has shown no evidence of a release from the wellhead or well.

The cause of the sheens remains under investigation.
