There Was 'Nobody in Charge'
After the Blast, Horizon Was Hobbled by a Complex Chain of Command; A 23-Year-Old Steps In to Radio a Mayday

In the minutes after a cascade of gas explosions crippled the Deepwater Horizon on April 20, confusion reigned on the drilling platform. Flames were spreading rapidly, power was out, and terrified workers were leaping into the dark, oil-coated sea. Capt. Curt Kuchta, the vessel's commander, huddled on the bridge with about 10 other managers and crew members.
Andrea Fleytas, a 23-year-old worker who helped operate the rig's sophisticated navigation machinery, suddenly noticed a glaring oversight: No one had issued a distress signal to the outside world, she recalls in an interview. Ms. Fleytas grabbed the radio and began calling over a signal monitored by the Coast Guard and other vessels.
"Mayday, Mayday. This is Deepwater Horizon. We have an uncontrollable fire."
When Capt. Kuchta realized what she had done, he reprimanded her, she says.
"I didn't give you authority to do that," he said, according to Ms. Fleytas, who says she responded: "I'm sorry."
An examination by The Wall Street Journal of what happened aboard the Deepwater Horizon just before and after the explosions suggests the rig was unprepared for the kind of disaster that struck and was overwhelmed when it occurred. The events on the bridge raise questions about whether the rig's leaders were prepared for handling such a fast-moving emergency and for evacuating the rig—and, more broadly, whether the U.S. has sufficient safety rules for such complex drilling operations in very deep water.
The chain of command broke down at times during the crisis, according to many crew members. They report that there was disarray on the bridge and pandemonium in the lifeboat area, where some people jumped overboard and others called for boats to be launched only partially filled.
The vessel's written safety procedures appear to have made it difficult to respond swiftly to a disaster that escalated at the speed of the events on April 20. For example, the guidelines require that a rig worker attempting to contain a gas emergency had to call two senior rig officials before deciding what to do. One of them was in the shower during the critical minutes, according to several crew members.
The written procedures required multiple people to jointly make decisions about how to respond to "dangerous" levels of gas—a term that wasn't precisely defined—and some members of the crew were unclear about who had authority to initiate an emergency shutdown of the well.
This account of what happened aboard the rig at the time of the explosions, which killed 11, is based on interviews with survivors, their written accounts, testimony to the Coast Guard and internal documents of rig operator Transocean Ltd. and well owner BP PLC.
In written responses to the Journal, Transocean said that the time between the first sign of trouble and the catastrophic explosion was too short for the crew to have done anything to effectively prevent or minimize the disaster. The company also said the rig's chain of command was in place and "did not hinder response time or activity."
At a Coast Guard hearing on Thursday, Jimmy Wayne Harrell, the top Transocean executive on the rig, acknowledged under questioning that a split chain of command on the platform could lead to "confusion" but it didn't hinder emergency response. At the same hearing, Capt. Kuchta said that communications had not been a problem.
Under pressure to step up his response to the Gulf of Mexico oil disaster, President Obama vowed tougher regulations for the oil industry. Joe White, Evan Newmark and Dennis Berman discuss. Also, a discussion on why 'Bluedog' Democrats caused a new jobs bill to falter.
BP declined to comment on anything that happened April 20.
In the minutes before the Deepwater Horizon exploded, almost no one on board realized that serious trouble was brewing, other than a few men on the drilling floor—the uppermost of three levels on the massive structure. The sea was as still as glass. A cool wind blew faintly from the north. Capt. Kuchta was hosting two BP executives on board for a ceremony honoring the rig for seven years without a serious accident.
Nearly 20 men, many of them close friends, were operating the drilling apparatus, which already had bored through more than 13,000 feet of rock about 5,000 feet deep in the Gulf of Mexico. No alarms had sounded that day signaling gas on the platform.
At about 9:47 p.m., workers all over the rig heard a sudden hiss of methane gas. Methane is often present in the ground in and near reservoirs of crude oil, and managing the threat is a regular part of drilling.
Within two minutes, pressure caused by gas in the well pipe had spiked dramatically, drilling records indicate. A torrent of methane gas struck the rig. Power failed throughout the vessel. "Everything started jumping up and down and rocking us," said Kevin Senegal, 45, a tank cleaner, in an interview.
Out on the water, 40 feet away, a 260-foot supply ship called the Damon B. Bankston was tethered to the rig by a hose. That ship's captain said in an interview that he saw drilling "mud," which is used as a counterweight to gas in the well, flying out of the drilling derrick like a "volcano." He radioed the bridge of the Deepwater Horizon. He was told there was "trouble with the well" and the Bankston should move 150 meters back. Then the channel went silent.
Micah Sandell, a 40-year-old with a wife and three children, watched with alarm from the rig's gantry crane, a massive device that moved across the main deck on a track. He radioed his crew to move away from the derrick.
Down on the deck, Heber Morales, 33, a former Marine from Texas, turned to the worker beside him. "Oh, man. That's not good," he said. The two moved away from the derrick.
Up in the crane, Mr. Sandell saw another worker on the deck, assistant driller Donald Clark, a 48-year-old former soybean farmer from Newellton, La., bolt for a set of stairs leading for the area where workers were fighting to control the well.
Ms. Fleytas, one of only three female workers in the 126-member crew, was on the bridge monitoring the rig's exact location and stability. Briefly, all the equipment went black, then a backup battery kicked on. She and her coworkers checked their monitors, which indicated no engines or thrusters were operational. Multiple gas alarms were sounding. One of the six huge engines that kept the floating platform stable was revving wildly.
No methane had been detected on the Deepwater Horizon before the massive gas jolt. So no "Level 1" gas emergency—according to Transocean safety regulations, when "dangerous" levels of gas are detected in the well—had been declared, according to crew members. That meant the crew had gotten no general alert to prepare for trouble and no order to shut down anything that might ignite the gas.
The rig's regulations state that in the event of such an emergency, the two top managers—on April 20 they were BP's senior person on the rig, Donald Vidrine, and Transocean's installation manager, Mr. Harrell—were to go to the drilling floor and evaluate the situation jointly. But once the gas hit, neither was able to get to the area.
Transocean says the rig's chain of command and safety standards were followed and worked effectively under the circumstances. Mr. Harrell didn't return phone calls. BP said Mr. Vidine was unavailable to comment.
When the pressure in the well spiked suddenly, the drilling crew had limited options and little time to act. Jason Anderson, a 35-year-old "toolpusher" who was supervising the crew on the oil platform's drilling floor, tried to divert gas away from the rig by closing the "bag," a thick membrane that surrounds a key part of the drill mechanism. That didn't work.
Four emergency calls were made from the rig floor to senior crew members in the moments before the blast, according to a BP document reviewed by the Journal. One went to Mr. Vidrine, according to notes about a statement he gave the Coast Guard that were reviewed by the Journal. The rig worker, who isn't identified in the notes, told him the drilling crew was "getting mud back," a sign that gas was flooding into the well. At that point, Mr. Vidrine rushed for the drilling floor, but already "mud was everywhere," he told the Coast Guard.
At about 9:50 p.m., Stephen Curtis, the 40-year-old assistant driller working with Mr. Anderson, called the rig's senior toolpusher, Randy Ezell, who was in his sleeping quarters, according to a statement given by Mr. Ezell to the Coast Guard. Mr. Curtis said that methane was surging into the well and workers were on the verge of losing control.
Two rig workers who later discussed the matter with Mr. Ezell said he was told that Mr. Anderson was going to trigger the blowout preventer, a 450-ton device designed to slice the drill pipe at the ocean floor and seal the well in less than a minute. If triggered in time, it might have been enough to prevent the explosions, or at least limit the scale of the disaster, say some drilling experts. Mr. Ezell prepared to go to the drilling floor, according to his statement.
Seconds later, the methane ignited, possibly triggered by the revving engine. That set off an explosion that blew away critical sections of the Deepwater Horizon, sheared off at least one engine, set large parts of the rig on fire and allowed oil to begin spewing into the sea.
Mr. Curtis, an ex-military man who enjoyed turkey hunting, and Mr. Anderson, a father of two who was planning to leave the Deepwater Horizon for good at the end of his 21-day rotation, almost certainly were killed instantly, according to other workers. So was veteran driller Dewey Revette, 48, from State Line, Miss. Six men working nearby also died. They included 22-year-old Shane Roshto and Karl Kleppinger, Jr., 38, from Natchez, Miss., and Mr. Clark, the assistant driller who had rushed to the stairs to help out.
Dale Burkeen, a 37-year-old Mississippian who operated the rig's tall starboard crane, had been trying to get out of harm's way when the blast hit. It blew him off a catwalk, other workers say, and he fell more than 50 feet to the deck, where he died.
A series of detonations followed. The motor room was wrecked. Steel doors were blown off their hinges. The wheel on one door flew off and struck a worker. Crew members were hurled across rooms, leaving many with broken bones, gashes and serious burns.
When he heard the first explosion, toolpusher Wyman Wheeler, who was scheduled to go home the next day, was in his bunk. He got up to investigate. The second blast blew the door off his quarters, breaking his shoulder and right leg in five places, according to family members. Other workers scooped him up and carried him toward the lifeboat deck on a stretcher.
The explosions knocked gantry-crane operator Mr. Sandell out of his seat and across the cab. As he fled down a spiral staircase to the deck, another explosion sent him into the air. He fell more than 10 feet, then got up to run. "Around me all over the deck, I couldn't see nothing but fire," he said in an interview. "There was no smoke, only flames." He ran for the lifeboat deck.
From the bridge, Chief Mate David Young ran outside to investigate and to suit up for firefighting. After he encountered only one other crew member in gear, he returned to the bridge. Crew members say no significant firefighting efforts were undertaken. "We had no fire pumps. There was nothing to do but abandon ship," said Capt. Kuchta, in testimony at a Coast Guard inquiry on Thursday.
As workers poured out of their quarters, many found their routes to open decks blocked. Ceiling tiles and insulation were blown everywhere. In some areas, fire-suppression systems were discharging carbon dioxide. Stairways were gone.
According to many workers, most crew members didn't get clear direction from the bridge about what to do for several minutes. Finally, the public-address system began to blare: "Fire. Fire. Fire. Fire on the rig floor. This is not a drill."
Many crew members couldn't reach their designated assembly areas. Scores scrambled instead toward the only two accessible lifeboats, which hung by cables 75 feet above the water on one side of the rig. Each enclosed and motorized boat could hold about 75 passengers.
"The scene was very chaotic," said worker Carlos Ramos in an interview. "People were in a state of panic." Flames were shooting out of the well hole to a height of 250 feet or more. Debris was falling. One crane boom on the rig melted from the heat and folded over.
Injured workers were scattered around the deck. Others were yelling that the rig was going to blow up. "There was no chain of command. Nobody in charge," Mr. Ramos said.
"People were just coming out of nowhere and just trying to get on the lifeboats," said Darin Rupinski, one of the operators of the rig's positioning system, in an interview. "One guy was actually hanging off the railing…. People were saying that we needed to get out of there."
At one point, a Transocean executive was standing partly in the lifeboat, helping injured workers off the rig and telling Mr. Rupinski not to lower the boat yet. Rig workers piling in were shouting for him to get the boat down. "There had to be at least 50 people in the boat, yelling, screaming at you to lower the boat," Mr. Rupinski recalled. "And you have a person outside saying, 'We have to wait.'"
Terrified workers began jumping directly into the sea—a 75-foot leap into the darkness. Mr. Rupinski radioed the bridge that workers were going overboard.
A Transocean spokesman said the company hasn't yet been able to determine exactly what happened in the lifeboat loading area.
Capt. Kuchta and about 10 other executives and crew members, including Ms. Fleytas, were gathered on the bridge, which was not yet threatened by fire. When word reached the bridge that workers were jumping, Ms. Fleytas's supervisor issued a "man overboard" call.
The Bankston, now positioned hundreds of feet from the burning rig, picked up the call. Officers on that vessel had seen what appeared to be shiny objects—the reflective life vests on rig workers—tumbling from the platform into the water. The Bankston put a small boat into the water and began a rescue operation.
Messrs. Vidrine and Harrell, the two highest ranking executives, appeared on the bridge. Mr. Vidrine later told the Coast Guard that a panel on the bridge showed that the drilling crew, all of whom were dead by then, had already closed the "bag," the thick rubber membrane around a section of the well.
But the emergency disconnect, which would sever the drilling pipe and shut down the well, had not been successfully triggered. Some crew members on the bridge said the disconnect needed to be hit, and a higher-ranking manager said to do so, according to an account given to the Coast Guard. Then another crew member said the cutoff couldn't be hit without permission from Mr. Harrell, who then gave the OK. At 9:56 p.m., the button finally was pushed, with no apparent effect, according to an internal BP document.
Mr. Young, the chief mate who had left the bridge to survey the fire, told Capt. Kuchta that the fire was "uncontrollable," and that everyone needed to abandon the rig immediately, according to two workers on the bridge. Under Transocean safety regulations, the decision to evacuate was to be made by Capt. Kuchta and Mr. Harrell.
Capt. Kuchta didn't immediately issue the order, even though at least one lifeboat had already pushed away, according to several people on the bridge. At the Coast Guard hearing Thursday, several crew members said they weren't certain who issued the abandon ship order or whether one was ever given. Capt. Kuchta didn't return calls seeking comment, but in his testimony said it was obvious to all by that time that the crew should evacuate.
Alarmed at the situation, Ms. Fleytas recalled in the interview, she turned on the public-address system and said: "We are abandoning the rig."
Capt. Kuchta told everyone who remained on the bridge to head for the lifeboats, according one person who was there.
One boat was long gone. When they reached the boarding area, the second was motoring away, according to several witnesses. Ten people were left on the rig, including Mr. Wheeler, the injured toolpusher, who was lying on a gurney.
The deck pulsed with heat. The air was thick with smoke, and the surface of the water beneath the rig—covered with oil and gas—was burning. Crew members attached a 25-foot life raft to a winch, swung it over a railing and inflated it. Mr. Wheeler was lifted in and several others climbed in with him. As the raft began descending, Ms. Fleytas jumped in. The remaining people on the rig, including Capt. Kuchta, leapt into the Gulf.
Once the life raft reached the ocean, it didn't move, even as fire spread across the water. Some hanging on to its sides thought the heat of the rig was creating a draft sucking the craft back in. Terrified, Ms. Fleytas rolled out of the raft into the oil-drenched water.
"All I saw was smoke and fire," she recalled. "I swam away from the rig for my life."
Minutes later, the rescue boat from the Bankston plucked Ms. Fleytas and several others from the water. The crew of the small boat saw that a line attached to the life raft was still connected to the burning rig.
"Cut the line," yelled one Bankston crew member. Another passed over a knife, the raft was cut free, and the last survivors were towed away from the fire. All told, the Bankston rescued 115, including 16 who were seriously injured. A Transocean spokesman says that the fact that so many survived "is a testament to the leadership, training, and heroic actions" of crew members.
The crew of the Deepwater Horizon watched from the deck of the Bankston as the drilling platform burned through the night. More than 24 hours later, it sank in 5,000 feet of water.
