The DNV final report indicated that the second tube was the segment of the drill string that was ejected after being cut by the blow out preventer shears. On July 10, 2010, BP began operations to install a sealing cap, also known as a capping stack, atop the failed blowout preventer stack.
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed. [1] Modern wells have blowout preventers intended to prevent such an occurrence. An accidental spark during a blowout can lead to a catastrophic oil or gas fire.
Blowout Preventers often contain a stack of independently-operated cutoff mechanisms, so there is redundancy in case of failure, and the ability to work in all normal circumstances with the drill pipe in or out of the well bore. The BOP used in the Deepwater Horizon, for example, had five "rams" and two "annular" blowout preventers. [15]
On July 15, 2010, BP announced that it had successfully plugged the oil leak using a tightly fitted cap. The cap, weighing 75 tons and standing 30 feet (9.1 m) high, was bolted to the failed blowout preventer. It consisted of a Flange Transition Spool and a 3 Ram Stack and was a temporary solution.

The Cameron ram-type blowout preventer was the first successful blowout preventer (BOP) for oil wells. It was developed by James S. Abercrombie and Harry S. Cameron in 1922. [1] [2] The device was issued U.S. patent 1,569,247 on January 12, 1926. [3] The blowout preventer was designated as a Mechanical Engineering Landmark in 2003. [1] [2] [4]

Stocks and bonds are tumbling after the December jobs report came in much stronger than expected. Nonfarm payroll additions smashed forecasts, while the US unemployment rate unexpectedly fell.
HWCG’s core equipment includes two dual-ram capping stacks capable of operating in water depths through 10,000 feet. [8] These capping stacks can effectively shut-in and contain a subsea well. If a flow and capture is required, the system is capable of a process volume of 130,000 barrels of oily fluids per day and 220 million cubic feet of ...
