Okay I think I understand you are referring to the crimp in the riser upstream of the BOP.

That crimp occurred as I understand it when the Deepwater Horizon vessel sank. The vessel had connected to it a 21" riser running some 5,000 feet or so to the top of the BOP. When the vessel sank this riser went to the seabed with the vessel and where it bent over at the BOP is where the crimp occurred. The vessel about 1,300 feet or so away from the BOP if I remember reading correctly. This is just my understanding.

Here is a schematic and the crimp would be on top of the BOP.

If we can weigh it down why hasn’t it been done, would be the next logical question. :) I still don’t see a self restricting blowout.

I would of refered to that damage as a “kink” not a crimp.
