Transocean Worker Says Oil Rig Equipment Wasn't Recertified

On April 20 at 10:43 a.m., a young BP PLC engineer sent a 173-word email to colleagues aboard the Deepwater Horizon drilling rig.

The email spelled out a recent change to a key safety test that sparked confusion and debate aboard the rig.

Less than 12 hours later, the rig was engulfed in flames so hot they melted steel. Eleven workers were dead.

Yet more details are emerging on the missteps that may have led to the Deepwater Horizon explosion. Among them: The all-important blowout preventer wasn’t recertified in 2005, as required by federal regulations, one worker responsible for maintaining the equipment told investigators yesterday. Transocean tells the AP that the blowout preventer wasn’t recertified because it was being constantly maintained. Re-certifying the five-story device can take as long as three months, because it must be removed from the water and disassembled.
