Subsea Source Control and Containment
Optimization continues and improvement in oil collection is expected over the next several days. It will be a few days before an assessment can be made as to the success of this containment effort.
The volume of oil captured and gas flared is being updated daily on BP’s website, www.bp.com
The first planned addition will use the hoses and manifold that were deployed for the “top kill” operation to take oil and gas from the failed Deepwater Horizon blow-out preventer (BOP) through a separate riser to the Q4000 vessel on the surface, in addition to the LMRP cap system. This system is intended to increase the overall efficiency of the containment operation by possibly increasing the amount of oil and gas that can be captured from the well and is currently expected to be available for deployment in mid-June.
The second planned addition is intended to provide a more permanent LMRP containment cap system by directing the oil and gas to a new free-floating riser ending approximately 300 feet below sea level. A flexible hose then will be attached to a containment vessel. This long-term containment option is designed to permit more effective disconnection and reconnection of the riser to provide the greatest flexibility for operations during a hurricane and is expected to be implemented in early July.
In the meantime, work on the first relief well, which started May 2, continues and has currently reached a depth of 12,956 feet. The second relief well, which started May 16, is at 8,576 feet, and testing of the BOP is continuing. Both wells are still estimated to take approximately three months to complete from commencement of drilling.
Surface Spill Response and Containment
Work continues to collect and disperse oil that has reached the surface of the sea, to protect the shoreline of the Gulf of Mexico, and to collect and clean up any oil that has reached shore.
More than 2,600 vessels are now involved in the response effort, including skimmers, tugs, barges and recovery vessels. Operations to skim oil from the surface of the water now have recovered, in total, approximately 368,000 barrels (15.5 million gallons) of oily liquid.
The total length of containment boom deployed as part of efforts to prevent oil from reaching the coast is now over 2.2 million feet, and an additional 2.4 million feet of sorbent boom also has been deployed.
To date, approximately 37,000 claims have been submitted and more than 18,000 payments already have been made, totalling approximately $48 million. BP has received more than 152,000 calls into its help lines.
