pumpjack thank you for the reference to the GE H4 hydraulic connector that i believe performs the EDS function for drive off. I have taken the liberty to annotate a screen shot to assist those of us trying to learn the deepsea technology. Please anyone feel free to comment/re-annotate any errors.

I see that the H4 is rated for 15,000 psi. I am wondering if BP thinks they can release it after they get the bent riser off? If they can release the H4, then the DD II BOP with an other H4 on the bottom can mate to the stub that is sticking up out of what I think is the upper annular and you have high pressure containment capability on the stack, now only limited by the strength of the upper casings if there is a communication in that annular space.
If they can’t get the H4 to separate then they go with the modified beanie cap and seal with an LMRP perched above to provide some protection up the riser for kicks? This would have very little pressure capability.
Mudmat question. Perhaps they are like the Air Force uses for temporary runways near the line for like Harrier VTOL jets. It might be used to provide a solid landing spot for something heavy coming down. Something being staged to be ready at the seafloor. Perhaps like a BOP and perhaps a separate LMRP oh and perhaps a beanie cap… but I think that is already down?
Deep sea guy corrections appreciated from those that live this every day.
