 New BP chief called to testify in US Congress Washington (AFP) Oct 1, 2010 - US lawmakers asked new BP chief Bob Dudley, who officially took up his post Friday, to testify in Congress over the aftermath of the devastating Gulf of Mexico oil spill that began more than five months ago. "BP is responsible for the worst environmental disaster in US history," said Democratic Congressman Ed Markey, chairman of the House Energy and Environment Subcommittee. "Mr Dudley takes over the oil company at a critical point in the clean-up and compensation process and the American people are interested in hearing his plan to make the region's environment and economy whole once again." Nearly five million barrels of oil gushed into the Gulf after an April 20 explosion aboard the BP-leased Deepwater Horizon oil rig, putting a major dent in the region's multi-billion-dollar fishing and tourism industries, and destroying hundreds of miles of fragile coastlines. The House hearing will address "critical matters of safety in BP operations," Markey said. He had invited Dudley to testify before the panel in August, but the executive declined the invitation, saying he wanted to wait until he assumed his new functions as BP's chief executive, replacing Tony Hayward, a Briton who was criticized for his handling of the crisis. Dudley, a soft-spoken 55-year-old American, announced a powerful new safety division and overhauled BP's structure on Wednesday but said the move was not an admission of a previously weak safety culture. His arrival was welcomed by the markets, which saw BP shares rise 10 percent in three days, helping alleviate somewhat the company's massive losses over the spill. The British energy giant said it has already spent 11.2 billion dollars over the incident. BP on Thursday pledged to pay a record 15-million-dollar fine to the US government for releasing pollutants into the air at its Texas refinery. The penalty is the largest to date assessed for civil violations of the federal Clean Air Act's chemical accident prevention regulations. The settlement, which requires court approval, addresses violations during three incidents at the refinery: two fires, in March 2004 and July 2005, and a leak in August 2005. |
A team of scientists aboard the Greenpeace ship Arctic Sunrise reported results Thursday from 10 days of sampling around areas affected by the worst oil spill in history.
"From the measurements we've taken, we see clear signs of oxygen deficiency on a large transect starting at the Macondo wellhead, all the way 300 miles to the west," said Rainer Amon, a Texas A&M scientist who participated in the research.
"How much of oil and gas components are still in the water is something that we need to now investigate in the laboratory."
The expedition had four points plotted to the west of the well to investigate what is considered the main path of oil after the April accident that led to a massive release of crude oil.
They concluded that the dissolved oxygen level was not as low as scientists would have expected if a greater proportion of oil and gas had dissolved in the water.
This suggests that oil has not "disappeared" some have suggested, and that as much as three to four million barrels of crude from the disaster have still not been accounted for.
"Despite everything that BP and the government would like us to think, the truth is, the oil spill's impact is not over," said Greenpeace US research director Kert Davies.
"Scientists know better, fishermen know better, the people of the Gulf and certainly the clean up crews endlessly picking up tar balls know better. The government and BP need to be honest with everyone about the extent of the damage."
The researchers conducted a parallel study of sea lift, and obtained samples of sediment on the ocean floor at a depth of 1,300 meters (4,20 feet), eight kilometers (five miles) from the disaster site.
Some of the samples contained visible amounts of oil with a strong smell, said Greenpeace.
The samples have been sent to an independent laboratory for study and to determine the presence of chemical dispersants.
In October, other scientists will join the Greenpeace expedition, which used a submersible to dive to the ocean floor to study the effects of oil disaster in coral reef habitats and marine communities.
"What we want to do is to come up with a mass balance of how much oil was put in the water column, the sediment surface," Amon said.
"When we've analyzed all the samples we've collected for our work and that of our colleagues, we hope to come up with a pretty good estimate of how much of the oil and gas was put into the system. Hopefully we can then come up with good ideas of where that missing oil and gas has gone."
Some 205 million gallons of oil flowed into the Gulf after the April 20 explosion aboard the BP-leased Deepwater Horizon oil rig, impacting the crucial fishing and tourism industries and destroying hundreds of miles of the region's fragile coastal ecosystems.
