This is a 5x timelapse of the last few minutes of the install of the Flange Transition Spool on top of the BOP after the old riser flange had been removed by the Overshot Tool (see my last videos). The Transition Spool had a angled pipe at the bottom called a "Mule Shoe" to help wrangle the drill pipe sticking up above the riser flange. It also had cables on the points of its alignment pins to aid in pulling them into the proper location (using the 3" ports that old choke and kill lines went through) down the riser and through the flange).
It didn't seat fully on the first attempt, so they lifted it back up and set it down and got it on the 2nd try.
