BP announced Tuesday it is suspending work on the most critical piece of its $1.5 billion Liberty oil field development in the Beaufort Sea -- a massive drilling rig.
BP said it needs to begin a broad engineering review of the rig to address a number of problems that have arisen during the rig's construction on a man-made island.
"We've gotten to the point that we need to step back, take a time out and make sure that all of these systems, including some critical safety systems, are just like they need to be," said BP spokesman Steve Rinehart.
