Oil Rig Explosion

With the domes they are pretty limited on how much liquid they can handle on the surface, are they not?

Actually, I think I was right even though I don't know what I'm talking about.

It seems it's important that they get the right volume of pipe so they can maintain a manageable pressure to keep the dome in the right place and the oil/gas/water flowing up.

What I meant with the last post is that they have to have enough tanker capacity to process what they bring to the surface.

OK...so they don't plan to use these domes as a cap, but instead as a new piping system to send the oil to the surface for collection? Interesting. In that case, they do have to size their dome/pipe to make sure they don't lose too much pressure going to the surface. Also, this is a mix of water/oil/gas, so it's probably nasty multi-phase flow. I am just surprised they aren't capping at this point and worrying about collecting later. Maybe they don't feel they can effectively cap it due to the pressures.

Maybe I should take 5 minutes to actually read about this rather than just assume I know what they are doing from looking at one picture :).

Yep...the dome is really just a collector to collect the oil and begin funneling it up to the pumping system. This answers the primary question I had in the back of my mind about the cap dome. How do you get a sufficient seal against the ocean floor? My guess is that you don't, you just get the best one you can get. You just try to pump it as fast as you can to try to limit the amount of oil that does leak out.

yeah they said it would only cap 80% of the flow. not exactly perfect by any means

This can't help.

"Hurricane Forecasters See Worst Looming in 2010 Atlantic Season"

Perhaps most significantly, sea temperatures from the Cape Verde Islands to the Caribbean, where the storms usually develop, are above normal and reaching records in some areas.

“We have only seen that in three previous seasons, 2005, 1958 and 1969, and all three of those years had five major hurricanes,” said Jeff Masters, co-founder of Weather Underground Inc. “I am definitely thinking that this is going to be a severe hurricane season.”

Correct, they don't have a way of sealing the dome to the soft ocean floor so that's why they have to get the pressure balance correct.

I am going to go out on a limb here and say that this oil spill IS NOT THAT BAD. So far at least. Yea some fisherman are going to be unemployed for a little while but they will be reimbursed by BP and yea I might have to skip that shrimp cocktail and oyster rockefeller for a couple of months, but so far we havent seen any massive fish/bird kills and the white beaches of Destin are still untouched along with the majority of the marshes.

That's because the full effects of this spill have yet to be felt. It's not going to be on the level of the Exxon Valdez in terms of environmental impact, but it's still going to be pretty bad.

it's going to be bad. particurally with the way media works now. back in the day with the exxon valdez every idiot with an iphone can't post pictures of dead birds.

The herring population has never recovered in prince William sound. It's way too early to consider this spill's impact, considering it is still leaking more oil even now, and hasn't even traced the coast really.

Its not going to be worse than Katrina and media was saying that the oil was supposed to reach the FL beaches on Saturday, well its Wednesday and the media is now saying it will reach the coast in a "couple more days".

My bet is that the cap is put in place tomorrow and works, they do some more skimming with the oil absorbent booms and by July the all clear is sounded.

Thats my "contrarian view"

The problem is not what is happening right now. Or at least not the big problem anyways. The problem lies in what is going to happen to the ecosystem and the Louisiana/Mississippi/Alabama coastal waters after all the oil is gone. How long is it going to take for the ecosystem to get back to normal, if it even does go back to normal.

Not to mention, what is going to happen to offshore drilling? Most likely nothing of note, but who knows.

it's not worse than the most expensive man-made disaster in our history? Ok. Ecologically, it's going to get brutal I'm afraid.

The more conservative members on here think the oil spill highlights the need for MORE drilling, and we aren't going to start consuming less anyway. Hopefully we can get another 60 years between spills.

The levies were and are inadequate. The flooding and destruction of new Orleans was completely preventable.

it's a flood plain. me thinks it would have flooded if humans weren't there too.

They have been dumping surfactants like crazy, and this will help the oil problem (don't know what the side effects are). Also, the injections at the well-head are stopping the oil from reaching the surface. A problem is that the oil is still there and could definitely affect bottom-feeding organisms (like shrimp) in a very big way. It isn't that the oil spill isn't bad - it's going to be bad. It is whether or not the response is sufficient to keep it from reaching the coast. That's why they want them fairly far off the coast. Apparently the winds have set up very nicely in the last day or two to keep the oil out at sea. If that doesn't shift, maybe they can keep most of the oil from reaching the beaches.

I've heard that those chemicals could potentially kill some fish, especially those who remain pretty close to the surface(obvious).
