NEW YORK (CNNMoney.com) -- The three oil companies primarily involved in the Gulf of Mexico oil spill blamed each other Tuesday for the accident last month that left 11 workers dead and oil still spewing into the Gulf.
"Transocean's blowout preventer failed to operate," said Lamar McKay, chairman and president of BP America, according to prepared testimony. "Only seven of the 126 onboard the Deepwater Horizon were BP employees, so we have only some of the story."
Transocean (RIG) said the blowout preventer performed fine in tests just a week before the accident.
While it's still unclear why the blowout preventer did not work, Transocean chief executive Steven Newman said the preventer is not the ultimate cause the accident, and that it must have been a failure of the well's cementing or casing that holds the wells in place.
Either way, Transocean said it's the responsibility of the well's owner to set all specifications for the drilling process, including dictating how the well is drilled, how thick the steel walls will be, and the composition and timing of mud injections and cement injections.

"All offshore oil and gas production projects begin and end with the operator...in this case, BP," said Newman. "Here was a sudden, catastrophic failure of the cement, the casing, or both. Therein lies the root cause of this occurrence."
The well's cementing was done by Halliburton (HAL, Fortune 500). But Halliburton's chief safety and environmental officer, Tim Probert, said responsibility also lay with BP.
"Halliburton, as a service provider to the well owner, is contractually bound to comply with the well owner's instructions on all matters relating to the performance of all work-related activities," said Probert. "Halliburton is confident that the cementing work on the well was completed in accordance with the requirements of the well owner's well construction plan."
Senators were not impressed with the blame game.
We always want to blame the other guy. It's easier to pass the buck then to own up. Whether it's a marriage relationship, ministry relationship, or friendship - we'd rather sling mud then help clean.
Always been like this; thank you Adam & Eve.
But...that's no excuse.
The thing about the blame game is that just because we don't admit and claim our junk doesn't mean it just goes away. It's still exists. It's still a mess.
Where is our junk? It's in us. We still carry it around, and in doing so it becomes resentment, bitterness, and the basis for more future wrong justifications and blame passing.
Time to own up and start cleaning up.
Who do you need to acknowledge your wrong doings to?
Who have you blamed for wrongs that were really your own insecurities in action?
Who do you need to ask forgiveness of?
Who do you need to forgive?
No one wants to be a walking, breathing oil spill.
