As the federal and congressional probes continue into the causes of the Gulf oil rig explosion, new information is coming to light about the failure of a key device, the blowout preventer, to shut off the gushing well, which could have prevented the growing catastrophe.
And new questions are being raised about the testing of the preventers. At today's hearing before a House subcommittee, Rep. Henry Waxman, D-Calif., revealed that the blowout preventer had a leak in a crucial hydraulic system and had failed a negative pressure test just hours before the April 20 explosion. And at a hearing in Louisiana on Tuesday, the government engineer who gave oil giant BP the final approval to drill admitted that he never asked for proof that the preventer worked.
In addition, an oil industry whistleblower told Huffington Post that BP had been aware for years that tests of blowout prevention devices were being falsified in Alaska. The devices are different from the ones involved in the Deepwater Horizon explosion but are also intended to prevent dangerous blowouts at drilling operations.
Mike Mason, who worked on oil rigs in Alaska for 18 years, says that he observed cheating on blowout preventer tests at least 100 times, including on many wells owned by BP.
As he describes it, the test involves a chart that shows whether the device will hold a certain amount of pressure for five minutes on each valve. (The test involves increasing the pressure from 250 pounds per square-inch (psi) to 5,000 psi.) "Sometimes, they would put their finger on the chart and slide it ahead -- so that it only recorded the pressure for 30 seconds instead of 5 minutes," he tells HuffPost.
Mason claims that a BP representative was usually present while subcontractors performed the tests. ...
