Necessity really is the mother of invention.

Still no excuse for not having some plan ready to go on day one.

Here’s a question: Why don’t they put a concentric reducer, or in this case, a concentric increaser, at the end of the 4” pipe and at least make the “gathering” end larger?

Instead of sticking a tube inside the riser, why not put a larger diameter tube outside of the riser. That should capture all leakage from the broken riser.

Then you still have the leaking blowout preventer to deal with.

Yikes...that sounds like something the Doctor would tell your wife after coming out of the OR.

Enterprise to the rescue! Go ahead and pat yourself on the back and proudly display your huge ATTABOY. You've earned it!

Another report indicates the cause of the “dislodgement” was a collision with one of the ROV’s. It shouldn’t take them too long to get it reinserted.

These initial results are encouraging!

I keep searching for some dresser couplings we used years ago. I am surprised that no thought was given prior to drilling of having a robotically installed coupler with a hot valve. Just a thought. The technology is there, but I suspect the cost for a worse case scenario was too high, or imagination for the worst case was too low.

All my experience was onshore, however the coupling and valve work should hold up well to the depths involved (and without the flames or risk of explosion). I suppose there may be robotic shortcomings.

I would be grateful to any Freepers who are familiar with current offshore drilling methods to bring me somewhat up to date. Thanks.
