"A critical device at the center of an investigation into the Gulf oil rig explosion didn't undergo a rigorous recertification process in 2005 as required by federal regulators, a worker responsible for maintaining the equipment told investigators Wednesday.

Mark Hay of rig-owner Transocean said the blowout preventer — designed to prevent a spill in the case of an explosion — was not recertified because it was being constantly maintained. Recertifying the five-story device requires completely disassembling it out of the water and can take as long as three months to complete.

The device — which may be lifted from the seafloor a mile below the water's surface in the coming days — failed following the rig explosion. After the blowout, some 206 million gallons of oil spewed into the Gulf until mid-July, when a temporary cap stopped the flow. A permanent fix is expected to be put in place after Labor Day."
