I don't know. I'm just thinking about sealing any hole.

It may just be a matter of terminology at this point, but I am separating them by function in my mind. The top hat design doesn't need the cleaner cut because it likely isn't fitted with sealing mechanisms. It would just be lowered as close as possible and would then pull suction. The cap design would benefit from a clean cut because it is actually fitted with sealing mechanisms - and as you note, you can make a seal to a generally flat surface much more easily.

At least, that's how I'm distinguishing between them in my head...

Probably right, but I struggle with suction being able to efficiently manage with the pressure levels and current flows. Can't seem to get that to work in my head, so I keep assuming a seal there too.

In my mind, it would work a lot like the insertion tube, but just hopefully capturing more oil because of the upside down funnel effect. I don't know what the cavitation pressure is for oil, but my guess is that there has to be a pumping station somewhere near the BOP that the captured oil is run through and then pumped up to the surface. As long as it can handle about 500 gallons/minute, it would seem possible. (Now my mind is off racing on the thought that oil is lighter than water and that the pressure in the ocean at that depth would be higher than the pressure exerted by a column of oil that high...so maybe they get some extra help from that pressure effect..not sure...too late to process that :) ).

I am with you on the problems of a non-sealed approach. They are probably going to pull a lot of water in with the oil they capture. The closer they get the top hat to the top of the LMRP, the more oil and less ocean water they pull in. They may try to put force down on the top hat to get it as close as they can, but it doesn't sound like there is any sort of gasket and the surface they will be mating to will be rougher since they aren't doing the diamond wire cut. It doesn't seem like there will really be a seal there.

If there are any huge sea beasts in the area, you are more likely to find them floating belly-up at the surface. Unfortunately.

actually I have seen fish swim by the camera a couple of times. Long (about a foot or so) and skinny fish.

here is an illustration of what could happen if it gets into Gulf stream, it was Tweeted by Jum Cramer about 5 minutes ago

YouTube - Ocean currents likely to carry oil to Atlantic

just heard CNN talking about the possibility that the water used in fighting the initial fire may have contributed to the demise of the above-water structure .....

It's difficult to tell how much is still spewing right now. Presumably less than it was an hour ago

Not so sure about that. The video that I seem to be getting right now shows the ROV holding the top of the top hat, with the hat still letting oil spew out of the top.

For a bit it looked like containment was mostly working, but I came back after a few minutes and it appears to be worse now.

Hard to tell when you are limited by camera angles, though.

I hope they aren't done, because it looks like a "fail" to my admittedly ignorant eye.

The first thing that should have happened after seeing how BP was handling the OIL SPILL, is control of the situation should have been turned over to military. Because all I have heard is that having the ability to work at that depth is tough, and BS. Well let me tell you that if there is one group/company/organization that does have the ability to work at those depths is the military. The only problem with letting them take control is the transparency fact. If control was to be handed over, it has to remain completly transparent.
I'm really thinking that nothing is going to be done, and they are just gonna let it blow it's self out.
