Fed'l inspections on rig not as claimed

Print

The federal agency responsible for ensuring that the Deepwater Horizon was operating safely before it exploded last month fell well short of its own policy that the rig be inspected at least once per month, an Associated Press investigation shows.

In fact, the agency's inspection frequency on the Deepwater Horizon fell dramatically over the past five years, according to federal Minerals Management Service records. The rig blew up April 20, killing 11 people before sinking and triggering a massive oil spill in the Gulf of Mexico.

Since January 2005, inspectors issued just one minor infraction for the rig. That strong track record led the agency last year to herald the Deepwater Horizon as an industry model for safety.

The inspection gaps are the latest in a series of questions raised about the agency's oversight of the oil drilling industry. Members of Congress and President Barack Obama have criticized what they call the cozy relationship between regulators and oil companies and vowed to reform MMS, which both regulates the industry and collects billions in royalties from it.

Earlier AP investigations have shown that the doomed rig was allowed to operate without safety documentation required by MMS regulations for the exact disaster scenario that occurred; that the cutoff valve which failed has repeatedly broken down at other wells in the years since regulators weakened testing requirements; and that regulation is so lax that some key safety aspects on rigs are decided almost entirely by the companies doing the work.
