I pretty much agree with LG’s analysis on this. Too many problems all at the same time. they might have trouble killing this thing from the bottom in fact.
As to putting a new BOP on top of the one already in place, I think they are afraid that the integrity of the topside well structure has been compromised too much for that. Remember that 5000’ of riser and the deepwater horizon itself were anchored to that pivot point for two days before and during the sinking. That well head has withstood many extreme loads already and, if it were me making the decisions, I sure wouldn’t want to put any more stress on it at this point.
Good point.
