The Macondo blowout happened because a number of separate risk
factors, oversights, and outright mistakes combined to overwhelm the
safeguards meant to prevent such an event. The Chief Counsel‘s team
identified a number of technical risk factors in the design, execution,
and testing of the Macondo well. The team was also able to trace all of these
failures back to an overarching failure of management. Better management of
personnel, risk, and communications by BP and its contractors would almost
certainly have prevented the blowout. The Macondo disaster was not inevitable.
