BP (NYSE:BP) executive vice president Harry Thierens said in a hearing today that Deepwater Horizon owner Transocean (NYSE:RIG) changed a locking mechanism on the blowout preventer which caused up to 24 hourse of delay.
The blowout preventer is what is used to prevent oil from leaking from a well if something fails. It took a minimum of twelve hours, and up to a full day to figure out what changes Transocean had made to the device and to receive drawings of those changes.
Thierens testified he had been immersed in the efforts to shutdown the oil well after the April 20 explosion.
BP is now trying to secure the failed device at the well without damaging it so a determination as to why it failed can be made, along with who is liable for the failure.
Cameron International (NYSE:CAM) provided the blowout preventer for the oil rig.

Who came up with the idea of using "Shocker" in the headline for this article? Such a description should be reserved for something truly shocking. Otherwise you are crying wolf and lowering the credibility of your publishing.
