Yes. Here is a recorded video of them working on the choke and kill flanges.

Dang! ROV pulled away before they could get that last bolt out. I think there was a big flare-up from the riser and they didn’t want to get slimed.
Wow. Watched the vid - I have to say that a lot of folks are bagging on the BP crew - but I am impressed.
And I am truly praying for their success.
