Maybe, maybe not: Discovery of second pipe in Deepwater Horizon riser stirs debate among experts
T second pipe won’t affect the cap. Any problems now will be deep in the well string.
They CUT those two pipes out of the top of the BOP before ‘seating’ the TRANSITION SPOOL. It was ‘seated’ late last night, and it took until early this morning to finish tightening the bolts.
The seating of the CAP (which is actually a JUNIOR BOP with a sealable cap) is done at the TOP of the Transition Spool, which is at least 10’ away from where those ‘pipes’ used to stick out of the top flange of the BOP.
So... even if they were there, they would not interfere with installation of the NEW BOP assembly.
