Bad management has been blamed for the BP oil spill, which killed 11 people in the Gulf of Mexico last year.

In a 48-page report, the presidential commission said that the failures by the companies involved in the spill were “systemic” and that another spill could happen again without industry and government reform.

The document stated that the Macondo well, which lies about a mile under the sea’s surface “blew out because a number of separate risk factors, oversights and outright mistakes combined to overwhelm the safeguards meant to prevent such an event from happening”.

But the report went on to say that “most of the mistakes and oversights at Macondo can be traced back to a single overarching failure – a failure of management”.

“Better management by BP, Halliburton and Transocean would almost certainly have prevented the blowout by improving the ability of individuals involved to identify the risks they faced, and to properly evaluate, communicate and address them,” the report continued.

The blast on 20 April 2010 leaked millions of gallons of oil from the well into the sea before finally being capped in July.
