The BP oil rig accident containment cap
July 13, 2010
BP is now testing a new cap over the leaking Deepwater Horizon well to determine whether it can stop the largest and possibly most destructive oil spill and oil rig accidents in United States history. Beginning noon Central Time, a 40-foot stack of valves which was affixed on top of the well will stop the flow of oil. With a tight new cap installed on its well, BP plans various gradual tests starting to see if the cap device can stop the oil. If the pressure inside the cap stays within the target range (8000-9000 pounds per square inch) for approximately six hours after the closing of the valves, many believe the cap could then contain the oil.
