BP's+Attempts+to+Stop+the+Leaks

· Inserting a new section of a pipe ringed with a gasket, to be inserted into one end of the leaking riser pipe. · The new pipe would pump the oil to ships on the surface
 * __ Four ways BP tried to stop the leak __**
 * 1) Double Pipe
 * 1) The Top Hat- a similar plan to Top Kill done after Top Kill failed
 * A small dome put over the leak to capture the oil and pipe it up to ships on the surface
 * The larger dome failed because ice-like crystals known as methane hydrates built up in the dome and plugged the outlet at the top that would have delivered the leaking oil to a tanker.
 * 1) The Junk Shot
 * use ground up rubber and plastic from old tires, golf balls and other items and inject it at high pressure down a three inch hose from the surface right into the blowout preventer.
 * The blowout preventer is a 450 ton device that sits over the well head and is used to control pressure. This device should have closed when the well began to fail, but it only closed partially.

BP KNEW OF PROBLEMS HOURS BEFORE BLAST · They hoped that that the junk would get caught between the partially opened teeth of the blowout preventer and form a barrier. After that, cement could be injected into the well to seal it up. In other words, they weren’t even sure of this plan. · They were to drill a second well into the failed well to stop the leak · The second well would join the failed well at the very bottom, in rock some 13,000 feet below the ocean floor. This would lower the pressure on the failed well, enough to allow a concrete plug to be placed into it and permanently shut it down. The relief well could also be used for future oil and gas production. · It took three months to complete, but finally stopped the leak.

We also created a presentation on the website Prezi. This will discuss all of our research on BP's attempts to stop the leak. There was also a misunderstanding with the topic, so our Prezi also includes info on the environment. We have also found a photo/video montage on youtube: [] []
