Blowout preventer Cameron International Corporation's EVO Ram BOP Patent Drawing (with legend) Patent Drawing of Hydril Annular BOP (with legend) Patent Drawing of a Subsea BOP Stack (with legend) A blowout preventer (BOP) (pronounced B-O-P) [1] is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas ...
Even with blowout prevention equipment and processes in place, operators must be prepared to respond to a blowout should one occur. Before drilling a well, a detailed well construction design plan, an Oil Spill Response Plan as well as a Well Containment Plan must be submitted, reviewed and approved by BSEE and is contingent upon access to ...
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.

BP (BP ) has been ordered to retrieve the section of pipe that has the blowout preventer, the mechanism that failed and helped to cause the explosion that wrecked the Deepwater Horizon rig, which ...
Failure of blowout preventer equipment was a major cause of the April 2010 disaster that killed 11 workers and resulted in an estimated 130 million gallons of crude oil spewing into the Gulf of.
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]
The blowout preventer is a T-shaped coupling that is screwed onto the top of the casing. It has a passage through the coupling for the drill string. There is a ram with a concave, semi-circular face in each arm of the tee. Each ram is moved in or out by turning its valve stem, which extends beyond the coupling. The ends of the stems are squared ...
A wellhead serves numerous functions, some of which are: Provide a means of casing suspension (Casing is the permanently installed pipe used to line the well hole for pressure containment and collapse prevention during the drilling phase).
