Ahhh... Gotcha. Sometimes it's good to get another person's perspective.
You are dead right: trying to undo all those bolts (even using crosspatterning) would very probably be a no-go right now. There'd be differential
forces and somewhere around the flange the thing would snag. Considering the mechanical work I've done over the last thirty-plus years I should've
realized that right away.
Just btw the device used for very quickly removing/tightening nuts is called a "rattle gun". They usually run on compressed air but they can also
Okay, so if they cut off the riser adapter completely then things should be pretty interesting for a while. If they don't and do welding instead,
it'll still be interesting, but on reflection I'm now leaning towards your option, namely they'll cut off the riser adapter.
It simply makes more sense. Far better to remove all that guff and create a clean work area and install a new LMRP cap (that they've doubtless been
working on for a while), than keep tagging bits on to what is a jury-rigged LMRP cap setup that's just getting bashed around 24/7 and is nowhere near
as efficient as it was in the first place.
Also I noticed some pretty substantial bracket-like parts that have been affixed to the sides of the section just below the bolted top. They could
lock-chain a new cap to them and get a pretty good seal if they run a double O-ring system -- one that would go around the outside of the inner,
newly-cut pipe and the second ring around its inner edge where it would seat outside the ring of nuts.
The thing is going to gush like crazy for a short while if they run the operation as you see it, but the long-term greater efficiency of a much
tighter LMRP cap would make it well worth doing the job.
