The Death of the Deepwater Horizon
The New York Times has pieced together, from testimony and interviews, what happened to the Deepwater Horizon drilling platform when the Macondo well blew out.
It has been eight months since the Macondo well erupted below the Deepwater Horizon, creating one of the worst environmental catastrophes in United States history. With government inquiries under way and billions of dollars in environmental fines at stake, most of the attention has focused on what caused the blowout. Investigators have dissected BP’s well design and Halliburton’s cementing work, uncovering problem after problem.The story reads like an action thriller, but it all happened. And 11 men died.
But this was a disaster with two distinct parts — first a blowout, then the destruction of the Horizon. The second part, which killed 11 people and injured dozens, has escaped intense scrutiny, as if it were an inevitable casualty of the blowout.
It was not.
Nearly 400 feet long, the Horizon had formidable and redundant defenses against even the worst blowout. It was equipped to divert surging oil and gas safely away from the rig. It had devices to quickly seal off a well blowout or to break free from it. It had systems to prevent gas from exploding and sophisticated alarms that would quickly warn the crew at the slightest trace of gas. The crew itself routinely practiced responding to alarms, fires and blowouts, and it was blessed with experienced leaders who clearly cared about safety.
On paper, experts and investigators agree, the Deepwater Horizon should have weathered this blowout.
This is the story of how and why it didn’t.
