What caused the BP Deepwater Horizon oil spill?

Answer 1

an explosion on board.
The oil line on the seafloor broke somehow. What happened exactly is still being determined.
The exact cause is unknown. There has been considerable speculation that the cement job performed prior to the blow out contributed to the blow out. Also, the blow out preventers (the "failsafe" measure) failed to actuate. It is still unknown if the accident was caused by human or mechanical reasons.

I have searched the internet for information, and believe the related link, from Wikipedia, has the best, unbiased, up-to-date information on events.

Answer 2

Looks like USA Halliburton 'screwed up'on the mud job and well capping, because well pressure not held.

USA Camerons' 'BOP' didn't work and in common with all other BOPs, was never fully tested at operating depth because USA MMS regulations do not require this.

All equipment was owned, operated and maintained by USA Transocean.

BP leased the rig and equipment for $500,000 a day.

Maybe BP will go to International Court and sue the above companies for compensation, only time will tell who's fault it was.

In the meantime BP are doing a great job covering all costs of spills and valid (?) claims, (by selling off assets), at the expense of their shareholders, mostly retired pensioners who need the dividend for their retirement.

Now shame on you Abama, US Senators and USA for disgracefully accusing BP of doing a business deal in return for maybe 'scapegoat' Lockerbie bombers release.

Answer 3

An explosion caused a fire aboard an offshore oil drilling rig. The explosion damaged the pipeline, causingpressurized oil to gush into the ocean.

Answer 4

Due to lack in BP oil drilling safety measures the oil rig exploded and when it collapsed it slammed into the pipe busting it and started this whole ordeal.

Answer 5

the oil spill WASNT IN bp. It was IN THE Gulf of Mexico.
