Remote operated vehicles (ROV) monitoring the wellhead used for in stricken Deepwater Horizon drilling platform in the USA finally ended operations today after no further leaks where found.
ROV have been monitoring the Macondo wellhead in the Gulf of Mexico since the drilling rig explosion and subsequent oil spill in 2010. The oil spill was caused when the sinking of the rig caused the 1.5km long riser pipeline – which connects the well on the sea bed to the rig on the surface – to rupture.
Operations by the ROV were observed by the US Coast Guard, Bureau of Ocean Energy Management, Bureau of Safety and Environmental Enforcement along with oil company and leaser of the rig BP and rig operator Transocean and confirmed no further oil could be seen leaking from the well.
“No apparent source of the surface sheen has been discovered by this effort,” said Federal on-scene coordinator for Deepwater Horizon Captain Duke Walker. “Next steps are being considered as we await the lab results of the surface and subsurface samples and more detailed analysis of the video shot during the mission.”
Following the oil spill, the Macdono wellhead was closed off and cemented to prevent more oil spilling on the shorelines of Louisiana, Mississippi and Florida in the Gulf of Mexico.
