looks like they whould move down, and get off the drill pipes tool joint.

Doesn't look like they have it in the shear deep enough. Might need to take another bite.

I would think that the curvature of the blades would force it deeper. Or are the blades straight?

The blade is curved. One of the Choke and kill lines is getting hung on the "tooth" of the clamp and may not completely shear it if it isn't deep enough in the shear.

For redstick: Shears did not cut the riser. Looks like they may go in perpendicular to where they crushed it and try again.

are they brining them to the surface now?

That's what it appears like, LEASTBAY.

Well that sucks.

shite.....the last 2 pages of this thread make me very unhappy.

so did they give up? shears?

I'd like to know the psi that those shears are putting out. I can't imagine how strong they need to be to shear a drilling riser.

is the rov surfacting too?
Posted on 6/1/10 at 1:21 pm to KappaSwig
maybe its just that rov surfacing
Posted on 6/1/10 at 1:27 pm to LEASTBAY
It is out of the water now

The claw is being taken to the surface to be reconfigured for a better cutting angle.

Copied this from another thread with no traffic. Why wouldn't this be tried when the riser is cut?
"IF there is room in the riser (after it's cut), I never understood why they can't just shove pipe straght down the hole (like they are drilling) and start the mud pumping "top kill" but actually already be 5000 to 10000 feet in the well?
At least that way they actually have the well "shut off" subsea. It also eliminates the well pressure being put on the BOP, which I know they are also trying to avoid. This LMRP is just a way of getting it to the surface but not ceasing the flow at all. Storms could jeopardize this setup easily."

Could they cut with a water jet cutter? Or a laser?
I've seen some of those water jet cutters do some amazing things to steel and concrete, but I have a feeling that the problem would be that they may not be as effective at depths like that. I haven't thought it all out, but being that the water from the jet has to be forced OUT at an enormous pressure, seems like the water pressure at 5K' would counteract a lot of it. Or maybe that is a simplistic analysis.
