Patent Drawing of a Subsea BOP Stack (with legend) A blowout preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowout, the uncontrolled release of crude oil and/or natural gas from a well. They are usually installed redundantly in stacks.
The sinking of the platform caused crude oil to gush out of the riser â the 5,000- foot pipe that connects the well at the ocean floor to the drilling platform on the surface. Attempts to shut down the flow failed when a safety device called a blowout preventer (BOP) could not be activated. The rate of oil release became the subject of intense debate. Throughout the first month of the spill, government responders officially adhered to what we now know were low and inaccurate estimates.
