The rule is expected to tighten safety requirements on blowout preventers, the industry-standard devices that are the last line of protection to stop explosions in undersea oil and gas wells. The explosion of the Deepwater Horizon oil rig on April 20, 2010, was caused in part when the buckling of a section of drill pipe led to the malfunction of a supposedly fail-safe blowout preventer on a BP well called Macondo.
It will be the third and biggest new drilling-equipment regulation put forth by the Obama administration in response to the disaster. In 2010, the Interior Department announced new regulations on drilling well casings, and in 2012, it announced new regulations on the cementing of wells.
