They are just about to cut the oil well riser with a giant cutter. The center tube is ~21" diam.

Right now it looks like the circular blade is stuck and they are trying to get it unfucked.

I'm surprised the page isn't plastered with google ads to help pay for the mess that has been created.



Maybe they should put a little water and oil on the blade!:ph34r:

They had some problems this morning, but it looks like they are trying again now.

I read that the jaws will close pretty slowly because the hyd power pack they're using has less flow than the cutter normally uses. It's totally closed around the riser now.

In theory, the shear will pinch the pipe shut and the oil leaking out will slow or stop.

Make what harder to close? The shear will smash the pipe as it cuts it. Not sure how well it will pinch it shut though. It looks like it has been cut now.

Creating two weak points, and and eye shaped hole!

This is not mild steal, is isn;t going to bend like lead!

Now they have a eye sahped hole, with two rips at each corner...creating 3 problems instead of 1!

They don't care how much leaks out of the sheared portion. They just cut the riser off so they could use a wire saw to cut the riser close to the top of the BOP stack. The ROV is there now. They should start running the wire saw soon.

Now that makes sense, totally different kind of cut!

Absolutely amazing video feed! A lot will be learned from this accident.

Yeah. Those "little" pipes that were running along side the riser were removed today after the shear jaws didn't look like they'd close around them Those little pipes are 7" OD with 2"(!) walls.

I'm not completely sure about what I'm looking at, but it looks like the cutting tool device is "hung up" on one of the flange bolts and the hydraulic cylinders can't draw the cutter to the pipe. So they're cutting the bolt head off. ?? Idunno:S
