Loose serious mistakes of the BP oil rig explosion

A series of errors from the violation of the Windows operating system to interrupt hangs arbitrary alarm led to the explosion and sinking of the BP oil rig in late April last. The disaster caused the largest oil decade has been clarified through the hearing of the U.S. Congress.

blast rig Deepwater Horizon.

black death
On 04.20.2010 the world's deepest oil rig Deepwater Horizon is located 50 miles Louisiana coast has exploded and sank, 11 people died. According to current estimates there are about 700 million liters of crude oil spill into the sea. Three months after the explosion, the new BP leaks this course successfully. But nothing sure the leak will stop completely.
So far there are 43,100 people, with 6470 vehicles waterway, and dozens of aircraft took part in remedial work, the total cost could reach 70 billion dollars.
Michael Williams, one of the top engineers at the oil rig has testified before congressional committees investigating the United States said Friday, 23/07/2010. He had escaped death by jumping out promptly rigs are burning up as fireball. He said many important key system has been corrupted. One of the warning system was often confused alarms so the workers had been off work a year before the explosion. "They do not want to beef up at 3 am because a false alarm."
Alarm system if not interrupted will promptly warn workers about the amount of methane gas being put together. But if such a report, the staff rig can not handle well. System has its own duty to prevent methane gas entering the cavity-place machine is easy to explode. Williams recounts that once the door of the chamber system computer automatically lock and accidentally major attraction of the engine has launched a shock from the door hinges. So popular can not stop flow of methane gas. (This system has terminated operations five years ago under a separate regulation for the entire staff here)

Green Death
They all said "green death" signals the Microsoft operating system crashes. According to Mr. Williams, this is usually at fault rig Deepwater Horizon. One of the computers still used by the operating system in 1990, was suspended several times to the rig all employees are to call it green death.
Although no signs that the computer failure led to disaster, complete generally showed the weaknesses of operating rigs while still using outdated technologies so.
Another witness, chief engineer Steven Bertone also said that there are problems with computers that have replaced the hard drive before the explosion.
History rig error was made clear in an inspection report seven months before the explosion. Tháng 9/2009 BP personnel discovered that the manager directly Transocean rig 390 has no error-repair in which many serious errors. To correct these errors need 3500 hours of labor, and until the date the disaster is still unknown what bugs have been fixed.

Someone has said before?
One expert said a few hours before the explosion was a test run to test four times. It seems that someone has felt out of trouble. Only experiments are not done properly.
On the rig everyone has the right to interrupt system operation if feels wrong somewhere. But there is not anyone doing this at all. According to an independent investigation, not least the worry of labor trouble error.

This has happened
The experts recognized the link between disasters and explosions Gulf of Mexico oil tanker Exxon Valdez two decades ago. On 24/03/1989, 41 million liters of oil spills from ships into the Pacific Ocean 1500 miles Exxon contaminating coastal areas of Alaska. Hundreds of thousands of sea birds, otters, seals, fish, whales have died because of pollution.
The knowledge collected in Alaska had not been ignored in the Gulf of Mexico, even the disaster prevention and pollution-president Walter Parker committees investigating the disaster, Exxon said. Commission investigations that time not only outlines the causes, but then also mentioned in the final recommendations for the future. According to Parker, the near-shore oil drilling should be adjusted, "unable reclining back, the industry boasts that the work was completed in a good way."

The fishing deaths
People are looking for answers for the future of the Gulf of Mexico coast of Alaska. Exxon oil pollution cases most affected to the fishing community because many populations has not yet revived. For example, herring is the source of the local fishing industry has not come back.
The environmental damage caused economic issues, health, social, and spiritual. In Alaska after this catastrophe, many people went bankrupt, while the number of suicides, divorce and crime increase dramatically.

Former countries long-term, general manager of the travel
According to the BBC, BP scientists being accused used the money to buy the silence of the researchers and academics most prestigious academy for the purpose of the expert opinion does not undermine their BP's weak position in the compensation case.
"In fact, a large company trying to buy the silence of the scientists as a whole" - Professor Cary Nelson, president of the Association of American University professor told the BBC.

BBC also obtained a copy of which contract proposal with BP scientists attached conditions and results for the BP research data not be made public for at least three years, or until the recovery plan the consequences of their Gulf of Mexico are government approved.
Professor Bob Shipp, head of marine science at the University of South Alabama also said BP would like to rent the entire department to plan the rehabilitation of the bay.
"We have set out the basic rules: In any research which, we must control the data, the research must be transparent, the final data should be exchanged freely with the Other scientific and editing can make science. So that all disappeared and we never hear again "-The dean stressed.
Professor Cary Nelson of the BP for that job worrisome because "the silence of the scientists doing research tasks that affect the ability of the entire country in the assessment of disaster, as well as the make policies and decisions. " He added, "I think, to what extent the fact that BP is antagonistic to the American citizens."
According to BP's announcement, so far it has worked with dozens of researchers, scientists who have "specialized knowledge about the Gulf of Mexico resources" and they did not preclude the notification of data researchers.
BBC news said: Some scientists are invited to collaborate with $ 250 per hour
This particular case of oil pollution, BP faced more than 300 lawsuits.
General Director of BP, Tony Hayward, a month ago, two days after the committee questioned before U.S. congressional hearing, was removed by private boat sailing with his son, rather than return to the scene. This is one reason why he should resign in the next few days, despite the backing of the board of directors and senior management. According to observers, BP was "experimental" to save his reputation was partly his tear.
