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.David Barstow, David Rohde and Stephanie Saul report for the New York Times on the Deepwater Horizon disaster.
Their training sessions contemplated a blowout coming up through only the drilling pipe. This one, it seemed, was erupting from the whole well opening. “I had no idea it could do what it did,” Mr. Holloway said.Human understanding of the forces of nature may be decent, but it still has a lot of holes in it.
Ms. Fleytas, 23, had graduated from maritime school in 2008 and had only been on the Horizon for 18 months. This was her first well-control emergency. But she had been trained, she said, to immediately sound the general master alarm if two or more sensors detected gas. She knew it had to be activated manually. She also knew how important it was to get crew members out of spaces filled with gas.posted by nomadicink at 6:54 AM on December 27, 2010 [4 favorites]
Yet with as many as 20 sensors glowing magenta on her console, Ms. Fleytas hesitated. She did not sound the general master alarm. Instead she began pressing buttons that told the system that the bridge crew was aware of the alarms.
“It was a lot to take in,” she testified. “There was a lot going on.”
Her boss, Yancy Keplinger, was also on the bridge. The alarms, in addition to flashing magenta, were making a warning sound. Mr. Keplinger said he kept trying to silence the alarms so he could think about what to do next. “I don’t think anybody was trained for the massive detectors that were going off that night,” he said.
Ms. Fleytas and Mr. Keplinger had another powerful tool at their fingertips — the emergency shutdown system. They could have used it to shut down the ventilation fans and inhibit the flow of gas. They could have used it to turn off electrical equipment and limit ignition sources. They could have even used it to shut down the engines.
They did none of these things.
Ms. Fleytas’s lawyer, Tim Johnson, said that with so much gas, explosions were all but inevitable. “I don’t think anything she could have done would have changed the situation out there,” he said. Mr. Keplinger’s lawyer, Steve Gordon, said the bridge crew faced “an insurmountable situation.”
As with the general master alarm, the effectiveness of the Horizon’s emergency shutdown system relied on human judgment. Transocean had been warned that the human element — the need for crew members to act quickly and correctly under stress — made the shutdown system vulnerable. In 2002, a safety consultant specifically urged Transocean to consider changing the system “so that human input is not critical for success.” Transocean says that having an automatic system is less safe.
Ms. Fleytas said it never occurred to her to use the emergency shutdown system. In any event, she explained, she had not been taught how to use it. “I don’t know of any procedures,” she said.
geoff.: The most depressing thing about this, is that if they automated a bit more, it seems so much could have been prevented. They had all the sensors and computer systems in place, and for the most critical functions, they relied on human judgement.I see what you mean, but I wonder if that really would have helped. Humans are constantly overriding automatic safety systems intended for their protection.
Her boss, Yancy Keplinger, was also on the bridge. The alarms, in addition to flashing magenta, were making a warning sound. Mr. Keplinger said he kept trying to silence the alarms so he could think about what to do next. “I don’t think anybody was trained for the massive detectors that were going off that night,” he said.Several paragraphs later, it's noted that she didn't know how to shut down the systems as she'd never been trained it. Yes, it's clear that Fleytas could have reacted better but it's extremely clear that those higher up the chain of command with more experience also failed to react well. Your singling out of her seems odd.

After the explosions, the chief engineer, Steve Bertone, raced from his room to the bridge. He did a quick survey of the rig’s condition. Its engines were dead. There was no power. The phones didn’t work. When he tried the handheld radios, they didn’t either. Meanwhile, he later wrote in a statement to the Coast Guard, Captain Kuchta was screaming at Ms. Fleytas for pushing the Horizon’s distress signal.Googling Freytas's name reveals that she tried to send out a distress call, got yelled at by the Captain and ended up saying "I'm sorry". Got that, she's sending out a general distress call because the rig is exploding and the she winds up apologizing for do so.
The paralysis had two main sources, the examination by The Times shows. The first was a failure to train for the worst. The Horizon was like a Gulf Coast town that regularly rehearsed for Category 1 hurricanes but never contemplated the hundred-year storm. The crew members, though expert in responding to the usual range of well problems, were unprepared for a major blowout followed by explosions, fires and a total loss of power.posted by nomadicink at 6:21 PM on December 27, 2010
They were also frozen by the sheer complexity of the Horizon’s defenses, and by the policies that explained when they were to be deployed. One emergency system alone was controlled by 30 buttons.
