Oil spill containment efforts could be putting strain on damaged well, New Orleans Times-Picayune, June 18, 2010:
Meanwhile, observers monitoring the video feeds from the robotic vehicles working on the sea floor have noticed BP measuring a tilt in the 40-ton blowout preventer stack with a level and a device called an inclinometer.
Odone, the BP spokesman, confirmed that his company has been monitoring the lean of the blowout preventer, which BP believes began tilting when the Deepwater Horizon rig sank and the riser pipe got bent. ...
Bea said BP isn't sharing enough information for others to know. If there is oil and gas escaping from the sides of the well, it could erode the sediments around the well and eat away at the support for all the heavy equipment that sits above. Bea said reports that BP is using an inclinometer is significant news. "It tells me that they are also concerned," he said.
