No, the RIT was inserted way near the end of the riser.
You can’t just cut away the damaged riser at the BOP since it’s uncertain how much flow the kink in the riser is holding back.
They now think it’s only ~15-20% of the flow. So Plan B is to cut away the LMRP (lower marine riser package, atop the BOP to which the riser is attached with a swivel joint), and try to bolt another ram or valve onto the BOP. Then close that valve.
I think they should try to hook up to the choke and kill lines, then, instead of pumping mud in (top kill), pump oil and gas out as fast as they can. This might alleviate the pressure difference across the BOP allowing them to cut away the LMRP and attach a ram/valve without a lot of oil flowing out the BOP.
Ai-yi-yi. I’m way in over my head here, Royal.
So, do you think pumping in the top kill is essentially a fool’s errand?
