NEW ORLEANS – BP took some of the blame for the Gulf oil disaster in an internal report issued Wednesday, acknowledging among other things that it misinterpreted a key pressure test of the well. But in a possible preview of its legal strategy, it also pointed the finger at its partners on the doomed rig.

The highly technical, 193-page report attributes the worst offshore oilspill in U.S. history and the rig explosion that set it off to a complex chain of failures both human and mechanical. Some of those problems have been made public over the past 4 1/2 months, such as the failureof the blowout preventer to clamp the well shut.

The report is far from the definitive ruling on the cause of the catastrophe. For one thing, government investigators have not yet begun to fully analyze the blowout preventer, which was raised from the bottom of the sea over Labor Day weekend.

But it provides an early look at the company's probable legal strategy — spreading the blame among itself, rig owner Transocean, and cement contractor Halliburton — as it deals with hundreds of lawsuits, billions of dollars in claims and possible criminal charges in the coming months and years.

Critics of BP called the report self-serving.

"This report is not BP's mea culpa," said Rep. Edward J. Markey, D-Mass., a member of a congressional panel investigating the spill. "Of their own eight key findings, they only explicitly take responsibility for half of one. BP is happy to slice up blame as long as they get the smallest piece."

The report's conclusions stand in contrast to a widely seen BP ad campaign in which the company casts no blame for the explosion and vows to clean up and restore the Gulf Coast.

"BP blaming others for the Gulf oil disaster is like Bernie Madoff blaming his accountant," said Robert Gordon, an attorney for fishermen, hotels and restaurants affected by the spill. Another plaintiff's lawyer, W. Mark Lanier, scoffed: "This is like the ringleader of a lynch mob saying, `Well, I didn't bring the rope; he did.'"

The disaster began when the Deepwater Horizon exploded off the coast of Louisiana on April 20, killing 11 workers. BP's well spewed more than 200 million gallons of oil into the Gulf before a temporary cap stopped it in mid-July.

Members of Congress, industry experts and workers who survived the blast have accused BP's engineers of cutting corners to save time and money on a project that was 43 days and more than $20 million behind schedule at the time of the blast.

Nearly 24 hours before the explosion, Halliburton was using cement to seal the gap between the well casing and the hole drilled in the seafloor. It was also cementing the bottom of the well shut until the day BP was ready to begin extracting oil and gas from it.

In its report, BP said that it was a bad cementing job that contributed to the blowout and that the design of the well was probably not to blame. It also said "more thorough review and testing by Halliburton" and "stronger quality assurance" by BP's well team might have identified weaknesses in the plan for cementing.

The report acknowledged, as investigators have previously suggested, that BP's engineers and employees of Transocean misinterpreted a pressure test of the well's integrity before the explosion.

"The Transocean rig crew and BP well site leaders reached the incorrect view that the test was successful and that well integrity had been established," the investigators said.

They also blamed employees on the rig from both companies for failing to respond to other warning signs that the well was in danger of blowing out.

The words "blame" and "mistake" never appear in the report. "Fault" shows up 20 times, but only once in the same sentence as the company's name.

"The team did not identify any single action or inaction that caused this accident," the investigators said. "Rather, a complex and interlinked series of mechanical failures, human judgments, engineering design, operational implementation and team interfaces came together to allow the initiation and escalation of the accident. Multiple companies, work teams and circumstances were involved over time."

Mark Bly, who as BP's safety chief led the internal investigation, said the report was a reconstruction of what happened on the rig based on the company's data and interviews with mostly BP employees and was not meant to focus on assigning blame. The six-person investigating panel had access to only a few workers from other companies, and samples of the actual cement used in the well were not released to BP.

Transocean blasted the report as a self-serving attempt to conceal what it called the real cause of the explosion — "BP's fatally flawed well design."

Halliburton said it found a number of omissions and inaccuracies in the report and is confident the work it completed on the well met BP's specifications. "Contractors do not specify well design or make decisions regarding testing procedures as that responsibility lies with the well owner," the company said.

White House press secretary Robert Gibbs noted "there is an active investigation into what went wrong" and said the administration's job is to find out what happened and hold those responsible accountable. Federal prosecutors are among those investigating.

In Wednesday trading in New York, BP stock rose $1.18, or 3.2 percent, to close at $38.37.

Investigators know the explosion was triggered by a bubble of methane gas that shot up the drill column and ignited. But they don't know exactly how and why the gas escaped. And they don't know for certain why the blowout preventer didn't work.

But in its report, BP said the blowout preventer didn't do its job because it was damaged in the explosion and because it had a bad valve and weak batteries. Transocean, which was responsible for maintaining the blowout preventer, has insisted the batteries were in working order.

BP also said:

• Its use of six centralizers during the cementing, instead of the 21 recommended by Halliburton, probably did not contribute to the cement's failure. Centralizers make sure the casing is running down the center of the well bore. If the casing is cemented off-center, there is a risk of an imperfect seal that could allow oil and gas to escape.

• Just before the blast, the flammable gas leaking from the well was directed onto the rig instead of being vented overboard. The rig's ventilation system may have allowed the gas to enter the engine rooms, where it may have ignited.

• Recommendations should be considered to improve offshore drilling practices. It suggested, among other things, that standards for reporting and investigating incidents be clarified and strengthened.

Separately on Wednesday, the Obama administration said it sent a sixth bill, for $128.5 million, to BP and others for costs associated with the spill. The first five bills, totaling $389.9 million, have been paid in full by BP, the government said.

The disaster has already cost BP roughly $8 billion, not including a $20 billion victims' compensation fund it has agreed to set up.

China uses oil-eating bacteria to clean up spill

China uses oil-eating bacteria to clean up spill

BEIJING (AFP) – Authorities in China are using over 23 tonnes of oil-eating bacteria to help clean up an oil spill in the Yellow Sea caused by a pipeline explosion and fire at the weekend, state media said Tuesday.

Yang Jiesen, head of the research and development division of a Beijing biotechnology company, said the Maritime Safety Administration had placed its order for the bacteria on Saturday, the official Xinhua news agency reported.

Dozens of oil-skimming vessels and hundreds of fishing boats were working to remove the slick off the northeastern port city of Dalian, after the accident on Friday that spilled an estimated 1,500 tonnes of crudeinto the sea.

"The use of the oil-eating bacteria at the Dalian spill is the first time China has made major use of biotechnology to solve an environmental pollution problem," the report said.

The process, known as bioremediation, uses microorganisms to break down some toxic hydrocarbons present in crude oil into less harmful compounds. It was used to help mitigate the 1989 Exxon Valdez oil spillin Alaska.

The Dalian incident has affected shipments of oil to southern China as the port has been partially closed, but refineries there are now processing inventories so oil prices are not expected to be impacted, Xinhua said.

Meanwhile, workers in Dalian are using oil barriers to prevent the slick from spreading, but are concerned wind and heavy rain could worsen the situation, it added.

So far, at least 460 tonnes of oil have been scooped up, according to the report, which gave no more details about the size of the spill.

According to previous news reports, the worst of the spill initially covered 50 square kilometres (19 square miles) but had been reduced to 45 square kilometres as of Monday.

But Xinhua reported then that a dark brown oil slick had stretched over at least 183 square kilometres of ocean.

China rushes to keep oil from international waters

BEIJING – China rushed to keep an oil spill from reaching international waters Tuesday, while an environmental group tried to assess if the country's largest reported spill was worse than has been disclosed.

Crude oil started pouring into the Yellow Sea off a busy northeastern port after a pipeline exploded late last week, sparking a massive 15-hour fire. The government says the slick has spread across a 70-square-mile (180-square-kilometer) stretch of ocean.

Images of 100-foot-high (30-meter-high) flames shooting up near part of China's strategic oil reserves drew the immediate attention of President Hu Jintao and other top leaders. Now the challenge is cleaning up the greasy brown plume floating off the shores of Dalian, once named China's most livable city.

The environmental group, Greenpeace China, shot several photographs at the scene Tuesday before their team was forced to leave. They showed oil-slicked rocky beaches, a man covered in thick black sludge up to his cheekbones, and workers carrying a colleague covered in oil away from the scene. His condition was not known.

Activists said it was too early to tell what impact the pollution might have on marine life.

In a stroke of awkward timing, meanwhile, Dalian's International Beach Culture Festival, which draws thousands of tourists every year, started over the weekend, but the state-run Xinhua News Agency said waters around the beach had not been affected by the slick.

Officials told Xinhua they did not yet know how much oil had leaked, but China Central Television reported that no more pollution, including oil and firefighting chemicals, had entered the sea Tuesday. It was not clear how far the spill was from China's closest neighbor in the region, North Korea.

Dalian's vice mayor, Dai Yulin, told Xinhua that 40 specialized oil-control boats would be on the scene by Tuesday evening, along with hundreds of fishing boats. Oil-eating bacteria were also being used in the cleanup.

"Our priority is to collect the spilled oil within five days to reduce the possibility of contaminating international waters," he said.

But an official with the State Oceanic Administration has warned the spill will be difficult to clean up even in twice that amount of time.

The Dalian port is China's second largest for crude oil imports, and last week's spill appears to be the country's largest in recent memory.

"In terms of what is known to the public, this is definitely the biggest," said Yang Ailun, spokeswoman for Greenpeace China.

"Government and business leaders have been telling the media that there's no environmental impact. From Greenpeace's perspective, that's very irresponsible," she added. "It's too early to tell. Oil is still floating around."

The cause of the blast was still not clear Tuesday. The pipeline is owned by China National Petroleum Corp., Asia's biggest oil and gas producer by volume.

Chinese media continued to report Tuesday on the initial explosion and the oil cleanup. The government is known to censor reporting when an issue becomes too sensitive.

While the Chinese public has not seized on the accident as its own version of the massive BP spill in the United States, warnings over the country's increasing dependence on oil were clear.

The International Energy Agency said Tuesday that China has overtaken the United States as the world's largest energy consumer, using the equivalent of 2.252 billion tons of oil last year. China immediately questioned the calculation.

"China was a spectator of the Gulf of Mexico incident, but suddenly it itself has attracted attention from the whole world," Sima Pingbang, the executive chief-editor of environmental protection website chinaepr, wrote Monday of the explosion and spill. "Chinese can no longer live above such things."

The slick of surface oil in the Gulf of Mexico spill was 2,700 square miles (7,000 sq. kilometers) late last week, far dwarfing the China spill.

But Yang worried that the scope of the Dalian spill was worse than reported so far.

"We need to send more independent voices out there," she said.
