Blah Blah Blah, I work in the industry, I know the plans they use as we had to implement them for our jobs for BP Thunderhawk. Probably some of the most strict rules I have EVER had to abide by. Had to reconfigure so much on our ship to make sure it was up to par for us to do the BP job.
I have read all the articles above already when they were released. Yes, maintenance should be vigorously checked at all times and that is being questioned for components on the rig, but it would have done nothing to keep that place afloat. You must not know how difficult to run/plan/create the safety plans for a disaster that sinks a 20,000 ton platform. (Very lightweight guess on poundage)
