HOUSTON – A submarine robot is seeking the source of a surface oil sheen that matched oil from the massive 2010 Deepwater Horizon oil spill, a spokesman for the U.S. Coast Guard said Monday.
The Coast Guard notified BP PLC (BP) and Transocean Ltd. (RIG) on Wednesday that a lab had matched the oil from the sheen to oil that gushed from the well drilled after the Deepwater Horizon drilling rig exploded, but said the source was still uncertain: the oil could have been trapped in the wreckage of the rig or from debris left on the seabed after the explosion. Transocean, the world’s largest deepwater driller, leased the Deepwater Horizon rig to BP.
Late Friday, the federal on-site coordinator for the Deepwater Horizon spill approved a plan put forward by BP and Transocean to investigate the source of the sheen. The companies submitted a response plan after the Coast Guard warned the two companies that they could be held responsible for additional costs associated with the sheen.
