Oil Rig Worker: Blowout Preventer was Leaking
(CBS/AP) A Deepwater Horizon worker has told the BBC he warned BP and its partners weeks ahead of the catastrophic explosion aboard the Gulf of Mexico oil rig that a crucial piece of hardware on the sea floor was leaking.
Tyrone Benton, who operates underwater robots that do the actual work on the complex, giant machinery a mile underwater, says one of the robot's cameras spotted a leak on a control pod of the blowout preventer (BOP).
The BOP is essentially the emergency shutoff valve fixed permanently to a wellhead on the seafloor. The Deepwater Horizon's BOP is as tall as a house and the control pods, of which this rig had at least two, are the brains of the machinery - a combination of mechanics and electronics.

"We saw a leak on the pod, so by seeing the leak we informed the company men," Benton told the BBC in an interview for its investigative program "Panorama," which airs Monday night.
He said his supervisors told BP and the company in charge of the BOP, Transocean, and their management teams made the decision to shut down the leaking control pod and rely solely on another, meant as backup.
"They have a control room where they could turn off that pod and turn on the other one, so that they don't have to stop production," Benton told the BBC's Hillary Anderson.
One expert on ocean oil drilling from the University of Texas called the decision to keep the BOP operating after the discovery of the leak "unacceptable."
"If you see any evidence of the blowout preventer not functioning properly, you should fix it by whatever means possible," professor Tad Patzek told the BBC for its report.
The decision appears to have been made to save money. Shutting down the entire BOP would have meant a complete halt to Deepwater Horizon's work - at a time when the BBC says BP was spending $500,000 every day to keep it running.
U.S. lawmakers have repeatedly accused BP of putting profits over safety in their operation of the rig.
In an interview with CBS News chief investigative correspondent Armen Keteyian just as BP attempted to plug the hemorrhaging BOP with a powerful blast of debris, company boss Tony Hayward said his "focus throughout my tenure as CEO, which is now just over three years, (has been) on safe and reliable operations… It's been our number one priority."
Can BP Be Trusted in Light of its Past?
Meanwhile, dozens of BP workers tasked with boring through thousands of feet of seafloor to bisect the gushing well and relieve pressure on the Deepwater Horizon well are getting on with their work, "business as usual."
CBS News correspondent Mark Strassmann reports that the relief wells need to reach a depth of 18,000 feet - and a target only about 7 inches wide - to allow BP to cap the leaking well. Currently, the drilling crews are at about 16,000 feet, but due to the unpredictable nature of the task at hand, it's still unclear whether BP will meet its mid-August goal to put a cap on this still-unfolding disaster.
