them. well, a blowout preventer works in two different ways. one, to shear the well off if the primary way doesn t work, which is to seal the pipe off. to test the bops it s what they call an integrity test to see if they hold up to the pressures. so what exactly is the claim you ve made about the testing that bp and its contractors have done on the blowout preventers? well, when they test the bops they re supposed to hold each test for five minutes, at 5,000 psi. to cut corners they hold the test 30 seconds or so on each one. they have a spin chart with an ink pen on the spin chart, they spin the chart ahead five minutes and then bleed the pressures off. you ve seen them literally, what, move a paper through a machine to indicate there s been a five-minute test when it hasn t been that long? yes, sir.
