Oil spill hearings: Dramatic testimony of the rig's final moments

This is an update from the joint hearings by the U.S. Coast Guard and Minerals Management Service held in Kenner on Friday into the explosion and fire aboard the Deepwater Horizon oil rig on April 20, which killed 11 workers and created the Gulf of Mexico oil spill currently fouling Louisiana's coast....................
The failed blowout preventer on the Deepwater Horizon oil rig had a hydraulic leak and a dead battery in one of its control pods, and testing in the hours before an April 20 explosion revealed that pressure in the well was dangerously out of whack.
While some data were being transmitted to shore for safekeeping right up until the April 20 blast, officials from Transocean, the rig owner, told Congress that
the last seven hours of its data are missing and that all written logs were lost in the explosion. Heavy drilling fluid was unconscionably replaced with lighter seawater against industry standards just prior to the blowout. Over heated objections by experts on the scene, BP management supervisors overruled drillers, and insisted on displacing the mud with seawater
The broken blow out preventer had not been inspected in over five years.
BP was in a severe economic and time crunch to finish the job quickly and were over six weeks behind schedule. Immediately leading up to the explosion, BP used procedures that
violated their own drill plan; and in spite of indications of a “very large abnormality,” kept testing until they got something they could disingenuously claim fulfilled the test.
BP management supervisors
refused to run the comprehensive cement bond log test, a definitive test of the integrity of a well’s cement mandated by Federal Regulations if there are concerns with the results of negative and positive pressure tests like were clearly present.
The BP management official on Deepwater Horizon making the unconscionable decisions, over the vehement objections of seasoned drilling experts, Robert Kaluzza has refused to testify by invoking his 5th Amendment criminal right against self incrimination.
BP officials aboard the rig
wanted to skip required pressure tests and tried to impose a drilling plan sent directly from BP’s Houston headquarters that had not been approved, as required, by the federal government’s Minerals Management Service.
