WASHINGTON – The agency that oversees offshore drilling will investigate the fire on an oil platform in the Gulf of Mexico.
Michael Bromwich, director of the Bureau of Ocean Energy Management, Regulation and Enforcement, says his agency will work with the Coast Guard to investigate the fire. The oil platform is owned by Houston-based Mariner Energy Inc.
Thursday’s fire came less than 5 months after the explosion of the Deepwater Horizon oil rig that killed 11 people and spurred the worst offshore oil spill in the nation’s history.
This time no one was killed and the Coast Guard said no crude was leaking.
And even though the Mariner platform was just 200 miles west of the site of the spill, everything from the structures to the operations to the safety devices were different.
Yet, when word spread of the latest mishap, Gulf Coast residents could only think of the 3-month BP spill that began after the drilling rig Deepwater Horizon exploded on April 20, killing 11 workers.
“It’s unbelievable,” said Sophie Esch, 28, a graduate student at Tulane who is from Berlin, Germany. “They should finally stop drilling in the Gulf. They should shut down all the drilling out there and not give permission to do any more. They’ve shown that it’s just unsafe.”
The Coast Guard initially reported that an oil sheen a mile long and 100 feet wide had begun to spread from the site of the blast, but hours later said crews were unable to find any spill. The company that owns the platform, Houston-based Mariner Energy, did not know what caused the fire.
Workers who were pulled from the water told rescuers that there was a blast on board, but Mariner’s Patrick Cassidy said he considered what happened a fire, not an explosion.
Platforms are vastly different from oil rigs like BP’s Deepwater Horizon. They are usually brought in after wells are already drilled and sealed.
“A production platform is much more stable,” said Andy Radford, an API expert on offshore oil drilling. “On a drilling rig, you’re actually drilling the well. You’re cutting. You’re pumping mud down the hole. You have a lot more activity on a drilling rig.”
In contrast, platforms are usually placed atop stable wells where the oil is flowing at a predictable pressure, he said. A majority of platforms in the Gulf do not require crews on board.
Many platforms, especially those in shallower water, stand on legs that are drilled into the sea floor. Like a giant octopus, they spread numerous pipelines and can tap into many wells at once.
The Deepwater Horizon was drilling a well a mile beneath the sea, which made trying to plug it after it blew out an incredible challenge, with BP trying techniques never tested. The platform was operating in 340 feet of water in a shallow area of the Gulf known as a major source of gas.
Responding to any oil spill in such shallow spots would be much easier than in deep water, where crews depend on remote-operated vehicles to access equipment on the sea floor.
Platforms do not have blowout preventers like deep water rigs that are supposed to shut down wells if there is problem. But they are usually equipped with a series of redundant valves that can shut off oil and gas at different points along the pipeline.
Mariner Energy officials said there were seven active production wells on its platform, and they were shut down shortly before the fire broke out. The Coast Guard said they would continue to monitor the platform to make sure no leaks.
Houston-based Mariner Energy said it did not know what caused the fire. The platform was still intact and a small portion appears burned, Cassidy said. Louisiana Gov. Bobby Jindal said the company told him the fire began in 100 barrels of light oil condensate.
Photos showed at least five ships floating near the platform. Three of them were shooting great plumes of water onto the machinery, an image similar to when the Deepwater Horizon exploded, Crews decided to let that blaze burn itself out, and the rig sank into the Gulf two days after the blast.
On the Mariner Energy platform, the fire was out less than 12 hours.
A Homeland Security update obtained by The Associated Press said the platform was producing 58,800 gallons of oil and 900,000 cubic feet of gas per day. The platform can store 4,200 gallons of oil.
All 13 workers aboard the platform were found huddled together, holding hands and all wearing life jackets when they were rescued from the water.
A captain of the Crystal Clear, a 110-foot boat that rescued them, said his craft was 25 miles away when it received a distress call.
When Capt. Dan Shaw arrived at the scene, the workers had been in the water for two hours and were thirsty and tired.
“We gave them soda and water, anything they wanted to drink,” Shaw said. “They were just glad to be on board with us.”
Shaw said workers told him the blast was so sudden that they did not have time to get into lifeboats. They did not mention what might have caused it.
“They just said there was an explosion, there was a fire,” Shaw said. “It happened very quick.”
Crew members were flown to a hospital and released by early Thursday evening.
Environmental groups and some lawmakers said the newest problem showed the dangers of offshore drilling, and urged the Obama administration to extend a temporary ban on deepwater drilling to shallow water.
“How many accidents are needed and how much environmental and economic damage must we suffer before we act to contain and control the source of the danger: offshore drilling?” said Rep. Frank Pallone, a New Jersey Democrat.
Mike Gravitz, oceans advocate for Environment America, said President Barack Obama “should need no further wake-up call to permanently ban new drilling.”
There are about 3,400 platforms operating in the Gulf, according to the American Petroleum Institute. Together they pump about a third of the America’s domestic oil, forming the backbone of the country’s petroleum industry.
Numerous platforms were damaged during hurricanes Katrina and Rita. The storms broke pipelines, and oil spilled into the Gulf. But the platforms successfully kept major spills from happening, Radford said.
“Those safety valves did their job,” he said.
Industry representatives sought to what happened Thursday and distance it from the well blowout in April.
“We have on these platforms on any given year roughly 100 fires,” said Allen Verret, executive director of the Offshore Operators Committee.
