A Deepwater Horizon rig worker has told the BBC that he identified a leak in the oil rig's safety equipment weeks before the explosion.
Tyrone Benton said the leak was not fixed at the time, but that instead the faulty device was shut down and a second one relied on.
"We saw a leak on the pod, so by seeing the leak we informed the company men," Mr Benton said of the earlier problem he had identified. "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."
Mr Benton said his supervisor e-mailed both BP and Transocean about the leaks when they were discovered.
He said he did not know whether the leaking pod was turned back on before the disaster or not.
He said to repair the control pod would have meant temporarily stopping drilling work on the rig at at time when it was costing BP $500,000 (£337,000) a day to operate the Deepwater Horizon.
