Economies and short cuts by BP and other firms contributed to last year’s disastrous Gulf of Mexico oil spill, a damning official inquiry has found.
A US presidential commission blamed “systemic” industry failures for last April’s rig explosion which killed 11 people and caused one of the worst oil spills in history – also warning they were likely to recur without major reform.
BP, Halliburton and Transocean, the three key companies involved with the Macondo well, made individual decisions that increased risks of a blow-out, but saved significant time or money, the report said.
“Most of the mistakes and oversights at Macondo can be traced back to a single overarching failure – a failure of management,” it concluded.
“Better management by BP, Halliburton and Transocean would almost have certainly prevented the blow-out.”
The April 20 blast as the Deepwater Horizon rig drilled in deepwater leaked millions of gallons of oil from the well into the sea before finally being capped in July. It has cost BP billions of dollars in clean-up costs and compensation, and also led to the departure of the energy giant’s British chief executive Tony Hayward.
The commission said: “Whether purposeful or not, many of the decisions that BP, Halliburton, and Transocean made that increased the risk of the Macondo blow-out clearly saved those companies significant time (and money).
“BP did not have adequate controls in place to ensure that key decisions in the months leading up to the blow-out were safe or sound from an engineering perspective.”
It added: “The blow-out was not the product of a series of abberational decisions made by a rogue industry or government officials that could not have been anticipated or expected to occur again.
“Rather, the root causes are systemic, and absent significant reform in both industry practices and government policies, might well recur.”
President Barack Obama set up the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling in May to investigate the spill, and recommend changes to industry and government policy.
The members questioned hundreds of people, reviewed thousands of pages of documents and conducted several public hearings.
Their report found that mistakes and “failures to appreciate risk” compromised safeguards “until the blow-out was inevitable and, at the very end, uncontrollable”.
BP’s “fundamental mistake” was failing to exercise proper caution over the job of sealing the well with cement, the commission said.
“Based on evidence currently available, there is nothing to suggest that BP’s engineering team conducted a formal, disciplined analysis of the combined impact of these risk factors on the prospects for a successful cement job,” the report added.
In its central conclusion, the report included a quote from an e-mail written by BP engineer Brett Cocales on April 16, just days before the disaster.
