Industrial Accidents
Deepwater Horizon
The industrial explosion whose environmental damage continued for months after the rig disappeared.
The knowledge that remained
Knowledge that outlived the failure.
- 01
Industrial failures can continue causing damage long after the visible structure is gone.
- 02
Worker safety and environmental containment are parts of the same failure system.
- 03
Consequences grow when access to the failed component is difficult.
The event became the largest offshore oil spill in United States history and an enduring case of industrial risk becoming an environmental catastrophe.

Approximately 134 million gallons are released before the well is capped.
The event.
Deepwater Horizon was drilling in the Gulf of Mexico when a blowout sent oil and gas up the well on April 20, 2010.
Eleven workers died. Wildlife, coastlines, and communities across the Gulf suffered enormous damage.
The mechanism.
A well blowout escalated into a rig fire, sinking, and uncontrolled oil release.
The rig exploded, burned, and later sank. After the structure disappeared beneath the water, the damaged well continued releasing oil into the Gulf.

The question to remember
Did the disaster end when the rig sank?
No. The visible fire ended, but the inaccessible well continued releasing oil into the Gulf for nearly three months.
