A spill of frozen bull semen bound for a breeder in the state of Texas triggered a scare on Tuesday that temporarily shut down a U.S. interstate highway during the morning rush hour.

The incident began when the driver of a Greyhound bus carrying the freight alerted the fire department he had lost a part of his load while negotiating the ramp on a highway near Nashville. “We didn’t know what it was, but we were told (the canisters) were non-toxic,” said Maggie Lawrence, a fire department spokeswoman.

When firefighters arrived on the ramp, they saw “four small propane-sized canisters (that) began to emit a light vapor,” Lawrence said. In addition to the vapor, the canisters also let off an unpleasant odor and the ramp was closed while emergency personnel tried to determine what was in the containers.

The bus driver turned around to retrieve the canisters. Once emergency personnel learned the smoking canisters were nothing hazardous and that they simply contained frozen bull semen that had been stored on dry ice, Tennessee Department of Transportation and fire department workers cleared the ramp.

There’s apparently no truth to the rumor the shipment was for Rick Perry’s weekly inoculation against brains and learnin’.

The blowout preventer that should have stopped the BP oil spill cold failed because of faulty design and a bent piece of pipe, a testing firm hired by the government said…in a report that appears to shift some blame for the disaster away from the oil giant and toward those who built and maintained the 300-ton safety device…

The report by the Norwegian firm Det Norske Veritas is not the final word on the Deepwater Horizon disaster last April that killed 11 workers and led to more than 200 million gallons of oil spewing from a BP well a mile beneath the Gulf of Mexico.

It helps answer one of the lingering mysteries nearly a year later: why the blowout preventer that sat at the wellhead and was supposed to prevent a spill in case of an explosion didn’t do its job.

The report cast blame on the blowout preventer’s blind shear rams, which are supposed to pinch a well shut in an emergency by shearing through the well’s drill pipe. In the BP crisis, the shear rams couldn’t do their job because the drill pipe had buckled, bowed and become stuck, according to the DNV report.

The 551-page report suggested that blowout preventers be designed or modified in such a way that the shear rams will completely cut through drill pipe regardless of the pipe’s position.

The blowout preventer was made by Cameron International and maintained by Transocean Ltd.

The report suggested that actions taken by the Transocean rig crew during its attempts to control the well around the time of the disaster may have contributed to the piece of drill pipe getting trapped.

“This is the first time in all of this that there has been a clear design flaw in the blowout preventer cited,” said Philip Johnson, a University of Alabama civil engineering professor who did not take part in the analysis. “My reaction is, ‘Holy smokes, every set of blind shear rams out there may have this problem…’”

Speculation on why the blowout preventer failed has persisted during the year since the disaster…

Johnson, the professor, said the report indicates that the blowout preventer had a design flaw that may have gone unnoticed by the entire industry, not just by Cameron.

RTFA if you feel you really need to know how each company’s lawyers attempts to pass the blame along to one or more of the other companies. Predictable.

The only item of substance – aside from laying the blame at the feet of Cameron International and Transocean – is that all the blowout preventers of this type may be potentially faulty. And that had better be changed real soon, folks.

Halliburton and BP knew weeks before the fatal explosion of the Macondo well in the Gulf of Mexico that the cement mixture they planned to use to seal the bottom of the well was unstable but still went ahead with the job…

In the first official finding of responsibility for the blowout, which killed 11 workers and led to the largest offshore oil spill in American history, the commission staff determined that Halliburton had conducted three laboratory tests that indicated that the cement mixture did not meet industry standards.

The result of at least one of those tests was given on March 8 to BP, which failed to act upon it, the panel’s lead investigator, Fred H. Bartlit Jr., said in a letter delivered to the commissioners…

Another Halliburton cement test, carried out about a week before the blowout of the well on April 20, also found the mixture to be unstable, yet those findings were never sent to BP, Mr. Bartlit found.

Although Mr. Bartlit does not specifically identify the cement failure as the sole or even primary cause of the blowout, he makes clear in his letter that if the cement had done its job and kept the highly pressured oil and gas out of the well bore, there would not have been an accident…

The failure of the cement set off a complex and ultimately deadly cascade of events as oil and gas exploded upward from the 18,000-foot-deep well. The blowout preventer, which sits on the ocean floor atop the well and is supposed to contain a well bore blowout, also failed…

The commission obtained from Halliburton samples of the same cement recipe used on the failed well, including the same proportion of nitrogen used as a leavening agent and a number of chemicals used to stabilize the mixture. The cement slurry was sent to a laboratory owned by Chevron for independent testing.

The mixture failed nine separate stability tests designed to reproduce conditions at the BP well and did not pass any, according to Chevron’s test results, which were returned to the commission this week.

Enough said. Now, we can look forward to years of politicians, pundits, pimps and lawyers delaying resolution of the disaster. Survivors be damned will be the rule of the day.

The sludge reservoir before it collapsed

The reservoir of an alumina plant in western Hungary burst on Monday, flooding several towns with towering waves of red sludge. Two people died, seven were missing and several dozen were injured, rescue services said.

The spill of an estimated 600,000-700,000 cubic meters of sludge affected seven localities near the Ajkai Timfoldgyar plant in the town of Ajka, 160 kilometers southwest of Budapest, the capital.

In Devecser, the sludge flooded some 400 homes, and 40 people had to be rescued in the neighboring town of Somlovasarhely. In Kolontar, the rushing sludge reached a height of two meters.

The sludge, a waste product in aluminum production, contains heavy metals and is toxic if ingested…

Some 120 people, including six who were seriously hurt, were treated by medical staff. Two of the injured were in life threatening condition. The most common injuries caused by the caustic sludge were burns on the skin and eyes, said Jozsef Czirner, the regional rescue service director.

What is there to say?

Give corporate creeps minimal standards and they will work very hard not to exceed them.

UPDATE: Death toll now up to 4.

BP was aware of equipment problems aboard the Deepwater Horizon rig hours before the explosion pumped millions of gallons of oil into the Gulf of Mexico, a congressional hearing was told yesterday .

In a second day of hearings, the House of Representatives’s energy and commerce committee said documents and company briefings suggested that BP, which owned the well; Transocean, which owned the rig; and Halliburton, which made the cement casing for the well, ignored tests in the hours before the 20 April explosion that indicated faulty safety equipment.

“Yet it appears the companies did not suspend operations, and now 11 workers are dead and the gulf faces an environmental catastrophe,” Henry Waxman, the chair of the energy and commerce committee, said, demanding to know why work was not stopped.

The committee heard testimony from oil executives suggesting multiple failures of safety systems that should have given advance warning of a blowout, or should have promptly cut off the flow of oil.

The failures included a dead battery in the blowout preventer, suggestions of a breach in the well casing, and failure in the shear ram, a device of last resort that was supposed to cut through and seal the drill pipe in the event of a blowout.

Nothing has changed since I worked in the offshore oil drilling industry, decades ago. Preventive technology has improved. The willingness of corporate bosses to take a position on the side of safety – still appears to be non-existent.

A bear gnawing on a fuel tank valve is suspected as the cause of a 1,000-gallon diesel fuel spill on British Columbia’s west coast. Sometime last weekend, a valve on the tank at a remote fishing camp in Rivers Inlet, 300 miles northwest of Vancouver, was opened, leading to a spill and creating an oil slick miles long.

Police found bite marks on a plastic bag placed over the valve, which Jacques Drisdelle, provincial coordinator for the Bear Aware advocacy group, told the newspaper isn’t unusual.

“A very hungry, desperate bear will go for fuel,” he said. “It has a sweet taste so they will consume fuel and oil.”

Life is like a box of chocolates – ain’t it?
