In Summary, BP's first idea of putting a big funnel over the top of the leak was a good start, but they did not anticipate the amount of methane hydrate slush that would clog the funnel. A possible solution is to build a heat exchanger inside the funnel and pump warm Gulf water to prevent the slush from forming. However, this may still be subject to ice crystals. It is surprising that a large oil company like BP does not have a team of engineers to solve this issue. Currently, a well kill is being attempted with around 20,000 people working on the project. Some suggest using a valve and wedge clamping to stop the flow, but this may not be effective. Another suggestion is to use detonations

I was flying back from Ky. last week and realized that the best engineers to design the tube I described, would be the ones that design for airdome sports stadiums. Close to or more than 100,000 people enclosed inside a fabric dome should demostrate the potential of the material.
I still think it is a good and low cost possibility, also I have figured out how to hold the ring in a controlled manor, while making it self center over the location, even after moving a considerable distance in any direction.

I did submit to BP and also found a contact well up the chain of command with FEMA.

It breaks my heart to see what is happening and to think August or beyond, what a mess.:frown:

Ouch! Someone didn't like my last post - an annoyed reply to Topher925's unhelpful, innaccurate &, in my view, time and space...

I'm sorry. I didn't realize that you're not only an expert in combustion and an ecologist, but a marine biologist as well. I did read your entire PDF, including this part:

Also mentioned is that whilst the combustion products are none too desirable, that they would be almost infinitely less damaging than the unburnt crud (sic). CO2 would be the largest undesirable combustion product, but that’s how most of the crud was destined to end up anyway. Although from a Climate Change perspective it is much longer lived than CH4, the latter does exhibit 22 times the Global Warming forcing that CO2 does. If, as may be the case, we are anywhere close to a Climate Change “tipping point”, it may be that it would be wisest to try to prevent/reduce the vast emissions of CH4 from the GOD, and live with the much less active CO2. The Pelicans, Bitterns, Dolphins … &c … would undoubtedly have preferred it this way ...

And while you go on and on about how it won't significantly affect global warming, that was clearly not my point. My point was referring to the local effects on ocean life and the very delicate ecosystem that the ocean possesses. Introducing several hundred tons of CO2 into the ocean in such a high concentration isn't going to make the pelicans, "bitterns", and dolphins happy. It will actually most likely kill them due to ocean acidification. A problem that is already becoming a serious environmental problem that will only be exacerbated by your "solution".

Thanks Om,
Glad you gave it a try.
I will likely get the same letter, unless our presentations are different enough based on numbers and description of design.
I mentioned the air bubble curtain and gave the PBS.org article about the whales as my source of thought inspiration. Don't know if a company or individual, presented what they are trying, I couldn't find the mention of what I saw on Diane Sawyer's segment of the evening news.

I told my wife I'll keep trying as long as anyone makes the mistake of listening:biggrin:
I'm thankful you like the basic idea, that has been a big boost for my morale.

It might be good that I try to make some good drawings, they will have to be hand renderings as I'm not skilled with any of the drawing programs.

I have also worked with the idea that this entire design can work in a completely submerged condition, 100 or 200 feet below the surface. I'm still trying to figure out the separation of the natural gas so that it does not react like your balloons.:rolleyes::smile:
Being below the surface would almost if not completely remove the effects of weather and surface conditions (maybe even a hurricane) Think of an air-dome stadium under water.:rolleyes:

Radical disasters require radical thinking (right ?):blushing:

Yes. This does require some radical thinking. With the knowledge of the volume of gas and oil coming out of the well, I've gone back to one of my old ideas.

But without knowing anything about the internal structure of the well head device, the following may not be feasible:

Successively insert a set of triangular flow restrictors, fashioned similarly to mountain climbing cams.

[PLAIN]http://www.mumc.org.au/gear/climbing/cam_large.jpg

Design such cams that they can be shoved down the throat of the well head, and the flow of oil will cause the cams to expand, locking the teeth of the cams into the sides of the pipe wall. Each cam device would restrict the flow of oil only partially. Setting in place as many of these devices as possible may reduce the flow to the point where the Horizon crew could contain the remaining flow.

And I won't tell you about my idea to weld, end to end, 4 derelict aircraft carriers to create a makeshift Troll to drop over the leak.

That sounds good, a little like the junk shot they tried. The push frame would have to be mounted to the pipe in order to move against the flow pressure of 3,000 psi ?? or more.
At those pressures anything that has flex or compression properties will pass through small cracks or holes like toothpaste out of a tube.
Restricting the flow completely would likely cause a blowout somewhere else.

The pressure is the reason they have avoided using any methods like this. They have to protect the head of the well or they could lose what containment they do have.

How about this to stop the oil leak. I am omitting all the little details.
1.) Make a large pressure vessel that can hold the pressure and is large enough to contain the blow out preventer.
2.) Have no bottom on this pressure vessel(cylinder) and attach a heavy flange on the top side. The flange is to receive a valve which is connected last. The flange bore should be larger than the leaking pipe diameter.
3.) Weld rebar on the inside surface of the vessel as rings. Attach two ports on the vessel. One four feet from the bottom and the second, close to the top.
4.) Set the vessel over the blow out preventer. The oil should continue to flow out the top flange. Some site cleanup might be required.
5.) Pump hydraulic cement into the lower port to fill the bottom four feet of the vessel. Wait a day for the cement to cure.
6.) Pump hydraulic cement into the top port until the oil starts forcing cement out the top flange. Make sure no hydraulic cement bonds to the top flange. Wait a day.
7.) Connect a valve (open) to the top flange and bolt down using their deep sea robotics. Don't forget the gasket in the connection.
8.) Close the valve and pray the cement holds.

That's one idea, but I don't think that stopping the leak is part of the plan. Why do I think this;
1.) It's been leaking for 72 days.
2.) Specific information of the problem is not released to the public.
3.) There's huge money to be made and lost in an oil clean up.
4.) Gas prices are low.
5.) BP website won't accept solutions unless they are in english.
6.) BP website is not user friendly.
7.) This disaster will allow big brother to grab more power.
8.) BP is not equiped to handle this disaster.
9.) Legally BP can only be sued to some limit.
10.) It's been leaking for 72 days.

I have not seen the "dispersant" issue addressed.

For a few thousand gallons of oil in the gulf a dispersant used to cover the mistake is normally used.

BP blindly assumed that the use of a dispersant in such a large body of water would work until they could come up with a fix for the leak.

Well, dispersant was a bad idea and is still a bad idea if one wants to contain the crude so that it can be collected. Not to mention the environmental damage it may be causing.

After the initial disaster the priority should have been to contain the spill to as small an area as possible. Adding dispersant to the gushing crude made that impossible.

The flexible tube to contain and direct the crude to an area that will allow collection sounds like a idea that will work in conjunction with the system they are now using. The pipe that they are now using could be used to help with the control of the flexible tube which could be placed around the pipe and anchored to the sea floor.

But, use of dispersants needs to be halted and taken out of the tool bag for oil spills! If anything, a way to bind the crude together should be explored, making collection an easier task. As it is now, with the dispersant contaminated crude, the ability to collect is extremely difficult if not impossible outside of that which is piped directly from the well head.

Did i mention that i think using dispersants is a dumb idea?!:smile:

Control and capture has always been my main thought, sometimes first actions are not the best. Here is a link for anyone to have, that helps in the knowledge of how things are being looked at.
Hope it helps set aside some fears about how bad some things are and how well the disaster is being monitored.

Received a reply!

"Dear RonL
Thank you so much for taking the time to think about and submit your proposed solution regarding the Horizon incident. Your submission has been reviewed for its technical merits. A similar approach has already been considered or planned for possible implementation. All of us on the Horizon Support Team appreciate your thoughts and efforts.

Sincerely yours,
Horizon Support Team"

Close to the same as your's, Om:smile:

I wonder how well the big ship will work ? and if a boat of some kind might run far enough ahead dragging a deep submerged air bubbling system, helping to bring the oil up that lies in large quantities far below the surface.
Should be an interesting few weeks ahead:smile:

I agree and think any oil that hits the shore is a bad thing. I really don't like anything that creates more mass to handle.
Anything that can suck it up while it is in suspension or floating on top of the water, should be a top priority.

I highly doubt it was overpressure. The BOP is rated for 15,000 psi. They were drilling with 14 ppg mud weight if I recall correctly and the well was in check at 18,000-ft or so.

(snip)

15,000 for an 18,000 foot hole? Cased with what is probably Chinese steel? Somebody call the suicide hot line.

I think you are completely wrong, we all could clean up our driving habits a little, but that is such a small part of what petroleum means in our modern world, I would like to challenge you to make a list of all the good things that come out of this industry. For every bad thing you should have many times more good ones.

I feel very bad about what has happened and the magnitude of the spill, but the things that need to be changed are better safety and a rapid response system for keeping things in better control while repairs are being made.

I have a few ideas about keeping oil from getting to the shore and a design or two for separating oil from the water, all hand powered. I will chose my method of presentation and to whom, a little better in hopes that dumb logic is not passed over in search for brilliant solutions.

Just hope you don't load yourself with too much undeserved guilt.

Hi Om,

Are those the headlight covers for the car you showed before, the one that had solar panels covering the back? It was red before?

That looks like an interesting car club.:approve:

Nope. That red car was mine, and it was gas powered. I traded it in last May for a 2009 Ford Ranger. Like boats, trucks have lots of room for electro-mechanical can-tinkery.

Since BP won't consider your totally tubular idea, the next step is to not have another oil spill, which involves some retro-innovation. As in hybridizing my truck. :smile:

I did find this little blurb, at the bottom of the first page, they will change out the risers and replace them with something more flexable, after a bad weather disconnect the ends will remain in suspension about 300' below the surface.

That idea is actually very similar to yours. They simply used a different material.

The one problem that I see with such a system is that with the exit so close to the surface, all of the methane will be coming up and out of the ocean in a much more concentrated area whenever the ships are disconnected. This is going to create an extremely hazardous environment for the ships to work in once they go back.

I'm starting to understand the logic of your 100 mile diameter containment ring.

What a bloody mess.

Most industrial and commercial engines are CI. It has been suggested runaway diesel generators were implicated in the disaster.

Why they weren't fitted with choke valves is beyond me.

Well you're right of course, the magnitude of good things coming out of petroleum may actually surpass the magnitude of wars, economic downturns, spills and environmental damage. My responsibility for the Horizon incident is responsibility, not guilt.

I keep hearing about how an implosion at the site, on the ocean floor, might seal off the gusher and the entire deposit. Is this too risky to try? I don't mean a nuke. Just a well placed charge.

I once had an 8 cylinder Detroit diesel engine that locked full open, when I tripped the emergency kill lever the vacuum became so great it sucked the seals out of the bearings, this allowed enough air to pull through that the RPM kept climbing. I was lucky that someone was close to the fuel intake line, he pulled it out in time that the fuel cleared the line and filters and the engine died before it flew apart.

Not sure what happened on the rig, but I understand that the best fail-safe device will not always work like planned. My engine was old and had not been operated often, the seals were likely dried and brittle?

I have seen this proposed many times, my thought is when the moment of ignition and explosion takes place everything is in a plasma or liquid state, the oil, gas and saltwater from the well is under such high pressure it will blow right through the explosion, the cold water of the gulf would eliminate all but a small amount of glass fusion.

Might not be very technical of a description, but this is what my mind sees.

What a bloody mess.

That largest ring I mentioned was 10 miles, and when I calculated the box containers for a single row at 22,700 or there about, I backed off that size and when you came up with a 17 years to fill a 1 mile ring, the 500' started to make sense.

My newest thoughts are will they ever come to the thinking of putting a boat on each side of the A-Whale with a boom between the boats and the ship, the booms attach just behind the skimmer openings and funnel oil in. This rig could maybe cover a 1/4 mile wide or more on each pass.

Welll...?

there is noting wrong with "conspiracy theory" if facts are collected then an informed decision is made.
the fact that useful news and information are being blacked out makes it darn'd near impossible to rely on main stream news anymore.

and many "theories" have quite a bit of truth, and some have even been proven right with time

Well, the first clue would be that you are reading a source (helium.com) that has no standards for quality as it is completely open for anyone to post anything. So you know that no one has checked the postings for crackpottery/accuracy.

Anyone interested in mechanical or ocean engineering might be worthwhile to look at the BP ops taking place. They plan to have a new cap in place by Monday and their ROV's are covering a lot of work going on.

http://www.bp.com/genericarticle.do?categoryId=9033572&contentId=7062605

The link again.

I made a folder in my favorites and labeled it BP ROV's, then open anyone of the ones listed and add it to the folder, after you list all 12 you can then open one, then open a new page and bring up another one, I find two per computer can give almost a full view of each screen.
Thanks to a tolerant wife, I have watched almost the entire week of work.

Time well WASTED.:biggrin:
