SHORT cuts and failures by management of BP contributed to the massive oil spill on the Gulf of Mexico, the official US inquiry has concluded.
The US presidential commission has warned that complacency in the industry could cause a similar accident in the future and urged major reform.
The explosion killed 11 people and caused one of the worst oil spills in history last April.
The rig burned for two days and then sank leaving oil spewing from broken pipes as engineers struggled to find a suitable plug.
"Most of the mistakes and oversights at Macondo can be traced back to a single overarching failure -- a failure of management," the commission concluded.
