UNH Coastal Response Research Center, NOAA, EPA and Coast Guard Convene Science Meeting to Study Dispersant Use and Ecosystem Impacts of Dispersed Oil in the Gulf of Mexico
May 28, 2010
Thursday, over 50 experts and practitioners from government, academia and industry finished a two-day meeting looking at the potential long-term impacts of the prolonged use of large volumes of dispersants in the Deepwater Horizon oil spill response efforts in the Gulf of Mexico.
This is the third time NOAA and EPA have gathered top scientists to discuss dispersant use since the spill began. EPA and NOAA scientists are conducting rigorous ongoing monitoring and analysis of the effectiveness and toxicity of the dispersants used.
Should data indicate that the dispersants are causing significant environmental damage that outweighs the benefits of their use, EPA and the Coast Guard reserve the right to discontinue use.
Although the crude oil is more toxic than the authorized dispersants, much is unknown about the long term environmental impacts of dispersants when used in these unprecedented volumes on the surface and in the subsea. Because of this and due to the effectiveness of subsea applications, EPA and the U.S. Coast Guard directed BP to significantly ramp down their use of dispersants. BP has complied and has significantly reduced dispersant use.
The purpose of the two-day meeting was to provide input to the Gulf of Mexico Regional Response Teams (4 and 6) on the use of dispersants and the effects of dispersed oil going forward in the Deepwater Horizon incident. The meeting also identified possible monitoring protocols to be used in the event of continued aerial applications to surface water and subsea use.
“This conference provided us with additional scientific information about potential impacts of prolonged dispersant use that can help guide decision-making as we continue to support the U.S. Coast Guard’s response to and clean up of this spill,” said Craig Carroll, EPA Co-Chair of the Region 6 Regional Response Team.
“It is the consensus of the group that up to this point, use of dispersants and the effects of dispersing oil into the water column has generally been less environmentally harmful than allowing the oil to migrate on the surface into the sensitive wetlands and near shore coastal habitats,” said Nancy Kinner, University of New Hampshire co-director of the Coastal Response Research Center.
“The meeting is adding to our knowledge, both in terms of helping identify key questions that should be asked and helping identifying new, quality sources of information and relevant expertise to draw on as we make these difficult decisions,” said Charlie Henry, NOAA’s Scientific Support Coordinator for the Unified Command Center in Roberts, La.
“The thoughtful scientific input from this meeting will prove valuable to responders as we continue to do everything possible to minimize damages caused by this unprecedented spill,” said Robert Pond of the US Coast Guard.
This was the third science summit in three weeks that builds on the unprecedented mobilization of science the federal government has brought to this incident. The Administration has engaged some of the world’s brightest scientific minds from the public and private sectors to mitigate the oil’s impact and ensure an effective response.
The results of the meeting will be presented in a report to the Regional Response Teams within the next week. The report will be available on the CRRC website at www.crrc.unh.edu.

As the nation’s leading scientific resource for oil spills, NOAA has been on the scene of the BP oil spill from the start, providing coordinated scientific weather and biological response services to federal, state and local organizations. More
Situation: May 28, 2010
BP’s efforts to kill the well continue. The initial efforts have been unsuccessful but BP restarted the “top kill” this afternoon and indicates that it may be another 24-48 hours before the operation can be evaluated. NOAA continues to prepare trajectories for the floating oil. A large amount of oil remains offshore of the Mississippi River Delta, but light and variable winds will reduce the potential for additional shoreline impacts over the weekend. The offshore trajectory for the tendril of sheen near the northern end of the loop current is also not expected to pose a threat for landfall through the forecast period.
NOAA’s Damage Assessment Remediation and Restoration Program is conducting a Natural Resource Damage Assessment. The focus currently is to assemble existing data on resources and their habitats and collect baseline (pre-spill impact) data. Data on oiled resources and habitats are also being collected.

- Underway on a SIP trawl cruise in western Louisiana waters to collect baseline samples.
Fishery closure update (effective May 28):
- NOAA Fisheries Service revised the fishery closure effective 6:00 p.m. EDT on Friday, May 28. The closure now encompasses approximately 25 percent of the federal waters in the Gulf of Mexico exclusive economic zone.
Marine mammals and turtles (effective May 27):
The total number of sea turtles verified from April 30 to May 27 within the designated spill area is 238. The 238 turtles verified include three entirely oiled sea turtles that were captured alive during dedicated on-water surveys last week: two small Kemp’s Ridley and a larger sub-adult Loggerhead turtle. They were taken to the Audubon Aquarium where they are undergoing de-oiling and care and are doing well.
In addition, 222 dead and 13 live stranded turtles (of which three subsequently died in rehab) have been verified. A total of 12 live turtles are now in rehabilitation. One of the live stranded turtles –caught in marine debris — was disentangled and released. One of the turtles that stranded dead – a Kemp’s Ridley – had visible evidence of external oil. All others that stranded dead and alive have not had visible external oil. Turtle strandings during this time period have been higher in Louisiana, Mississippi and Alabama than in previous years for this same time period. This may be due in part to increased detection and reporting, but this does not fully account for the increase.
From April 30 to May 27, there have been 24 dead dolphins verified within the designated spill area. So far, one of the 24 dolphins had evidence of external oil. It was found on an oiled beach. We are unable at this time to determine whether the animal was externally covered in oil prior to its death or after its death. The other 23 dolphins have had no visible evidence of external oil. Since April 30, the stranding
rate for dolphins in Louisiana has been higher than the historic numbers for the same time period in previous years. This may be due to increased detection and reporting and the lingering effects of the earlier observed spike in strandings.
*Strandings are defined as dead or debilitated animals that wash ashore

from my post on April 29, 2010 –
My Note about the oil spill from that day –
Those epic efforts out in the Gulf of Mexico to clean up the oil might have tried those pleated, white filters that are used on heaters – wired together in a long row, because water goes through them but oil does not. It would cost about $20 to get one and find out if it works or not, but it does which I accidentally discovered doing something else trying to filter cement dust out of the air at my parent’s house recently. Somebody needs to go out there and tell them, I’m not the one with a 600 mile wide oil spill, hundreds of people trying to manage it unsuccessfully and with crude oil heading towards the shore.
But, then I’ve been there and done that, so to speak. I’ve been to the beaches in California after an oil spill with the birds laying on the shore covered in black crude and brown gunk from the sand, flopping around with the sounds of dying. And, I’ve stepped over the blanket of tar laden kelp and smelled the fishes that lay dead and dying in the foam of the surf and along the beach.
I’ve used the Ajax powder to try and get the black petroleum off my shoes and off the carpets in the car after we all walked along that beach. I know the dread and horror of what that will be to the businesses and tourist industries along that entire gulf coast from Florida to Louisiana and Texas. But, then – you couldn’t tell them anything about drilling for oil out there in the Gulf – we need that oil – we need those revenues – we need those oil company leases paying off those rigs, etc., etc., etc.,
I can see those tourist brochures now – white sandy beaches covered in coal black mcnasty – oh well. Y’all come now, yah hear? Just like old Granny Clampett says – ya’ll just come on back and spend your money on vacation. And that’s going to be some shrimp jambalaya with a new kind of twang.
What were they thinking? Can I say that they can do as the Republicans suggest and tell each other it doesn’t exist, if they don’t agree with it? Maybe they can hire a pr firm and call it “black sand beaches” and “tar marsh nature lessons camp”. They are not going to like it when that stuff gets to shore, finishes getting to shore and then does what it always does once it is onshore.
Nope, they are not going to think much of the economic revenue that oil is at that point. But, then you just couldn’t tell them anything. Ask Haley Barbour – everything is fine . . .

From the first part of that post on the same day –
My Note – (earlier April 29, 2010) –
I am intelligent. I am intelligent enough to know this about myself and about the world in general, (see mantra below). It is, after considerable thought, what I can offer as my great contribution to this greater world. After reading pages and pages of US Code, International Law, Science, Economics, Business Finance and Wall Street lists of hedge funds, market makers and “deals” – I was reminded this morning, of something I wrote a long time ago when I lived with roommates who kept a war zone in our living room –
A mantra that I wrote during another troubled time in our history as a nation, (before 1990 something) –
It is called, “a mantra for the real world” –
It says –
I am an asshole. You are an asshole. We are all assholes. If we all shut down, shut up and don’t work together, the shit backs up and the world explodes. I am an asshole. You are an asshole . . . We are all assholes.
I think the original version was a little longer. It has been paraphrased by overuse.
– cricketdiane, 04-29-10
And then I forget that – and still find myself offended when I’m being an asshole or someone else is being an asshole or when some group of people or situation is intolerable and asinine.
The original version had something about “flow” in it – probably intended as a solution at the time beyond the recognition that we are the problem and therefore, the solutions as well.
Do you know, there are literally hundred of thousands upon thousands of pages of laws written precisely because humans, including me – are not inclined to play nice with one another on a regular basis? That is astounding.
It isn’t so astounding because we don’t play nice with each other some or even a lot of the time, it is astounding that someone thought enough of it to write it down, legislate it, take it to court, spend hours of their lives debating it, and academically, taught it, discussed it, intellectualized it, wrote about it, felt it necessary to review it, disseminate those reviews, alter it somewhat in how it was applied in case law somewhere at some time and for some reason along with paying thousands of lawyers and judges to adjudicate and consider it.
That is what is amazing.
I am literally dumbfounded by it.
There was a man who built a wall. His neighbor would have an advantage in having the wall along his property as well. The two had a talk over where the fence would be. The man who felt he could build the wall said he would and told the neighbor about his plans to do it.
So, ultimately when the wall was built, the man who put his time, labor and materials into building the wall that he wanted – sued the neighbor for payment for building the wall. Now, who would’ve thought that would take up pages and pages of written materials, discussion, thought, legal hours of representation for both sides and judges and orators and legislators and some of the brightest minds in our history to figure out?
But, aside from being an example intended to show a legal premise about rights, unspoken communication and commitments intended or otherwise, it is also an example of the massive consideration being given to the most trite of circumstances in human activities.
And it is the direct result of several very basic things – failure to recognize that the communication was not perceived nor received the same on both sides, failure to work together effectively – since both of the bastards should’ve been building the wall, and a massive failure by society to give these people the tools to work effectively together and play with one another appropriately at every stage of the event.
We have children and adults saying to one another, when they don’t like what was said or the way someone looked at them, that they’ll go get their gun. Well, that is no surprise reading the laws.
Apparently, that has been a problem which could’ve been solved a long time ago – with solutions that effect options for better resolutions and social tools in the hands of those people so that the only option on the menu wouldn’t be a gun or a bat or a weapon of permanent and irreparable harm.
That “beat the hell out of somebody” solution is always on the menu for any human being, but the tragedy and shame is for it to be the only solution on the menu for anybody, especially after this much of civilization has passed before us.
We have traders on Wall Street, money managers within investment firms and chief executive officers who were not even capable of hearing or understanding what the Senators on the investigative committee were saying to them.
It isn’t a failure of the Senators, their staff members and the general public to understand the language of Wall Street – it was the final analysis that shows, Wall Street is used to playing in a very isolated and rarefied atmosphere where everyone sees it the same way they do, where everything appears fine and wonderful, and where no one really knows what they are doing outside of that isolated and intellectually-biased sphere.
With the advent of the internet and resources of information broadly and immediately available, they failed to realize that everyone can know what they are doing and understand how they are doing it instantly. It isn’t hard to understand chicanery and con, there are pages and pages and pages of law devoted to it. Apparently, that is also a problem we could’ve solved a long time ago, by taking all those people and families whose trade involved finance and letting them sell to the “get a bat” people.
But, no . . . we wouldn’t do that.
I still agree with Chris Rock that the way to solve the problem of violence isn’t to outlaw guns – just raise the price of the bullets.
For $650 a bullet – it changes the idea of that solution. But, then we would have to outlaw 2 x 4′s.
(there is more on that post which doesn’t stop there obviously – but for what I want to bring forward today to remember and apply to the situation in the Gulf of Mexico that as of today, is 39 days after the explosion from the crude oil drilling accident that happened on the Deepwater Horizon and way out of hand to the extreme.)
– cricketdiane, from April 29, 2010 and the last note in parens – from today.
April 29, 2010
And then these –
April 30, 2010
My Note –
There have been news stories tonight on CNN about the oil spill and how they are expecting to fix it – I couldn’t believe that what they are suggesting will take 5 weeks of oil continuing to pump into the water. No – no – no – NO.
That is not acceptable.
I might not be down there helping with it but the least I can do is find something that will first work right now – faster than that. Then they can get along with whatever they’re doing.

Evening Buzz: Burning Gulf Oil Spill
Posted: 09:40 PM ET
“The slick stretches for about 100 miles across the north-central gulf and is about 30 miles wide at some points.
It’s within 16 miles of the mouth of the Mississippi, the U.S. Coast Guard reports.”
“Efforts to cap the well using remote-controlled submarines have failed. Louisiana officials fear the oil could reach the state’s shoreline late Friday or early Saturday and damage shellfish and wildlife.”
(NECN/CNN) – Officials say an oil spill in the Gulf of Mexico is much worse than originally thought.
“Wednesday night, the Coast Guard said about 5,000 barrels of oil — more than 200,000 gallons — are leaking each day. It is five-times worse than originally estimated.”
“Skimmers, barriers and oil absorbing booms are stacked ceiling high in a staging warehouse. They are the traditional means by which to fight an oil spill. But with an estimated total of 5,000 barrels leaking from three different areas per day, other methods are being tested — all in hopes of preventing massive damage to the coastline.”
Some authorities think this spill is getting worse, much worse. At first, the estimate was that the spill was leaking out about a thousand barrels of oil per day. Now, the Coast Guard is saying that’s increased to as many as 5,000 barrels. That’s more than 200,000 gallons per day.
(and – they knew the flimsy booms they were using were inappropriate at this point and didn’t get a better hard boom like the US Navy uses or other systems out to the area, my note today about the April 29 info from post)
AP Top News at 9:45 p.m. EDT
(AP) – 1 hour ago
VENICE, La. — An oil spill that threatened to eclipse even the Exxon Valdez disaster spread out of control and started washing ashore along the Gulf Coast Thursday night as fishermen rushed to scoop up shrimp and crews spread floating barriers around marshes. The spill was bigger than imagined — five times more than first estimated — and closer. Fingers of oily sheen were reaching the Mississippi River delta, lapping the Louisiana shoreline in long, thin lines.

The Coast Guard and the Minerals Management Service have launched an investigation on possible causes of the explosion. Production casing was being run and cemented at the time of the accident. Once the cementing was done, it was due to be tested for integrity and a cement plug set to abandon the well for later completion as a subsea producer. According to Transocean executive Adrian Rose “undoubtedly abnormal pressure” had accumulated inside the marine riser and as it came up it “expanded rapidly and ignited”, an event known as a blowout.
Due to potential oil spills which are likely during explosions, the Environmental Protection Agency’s teams were on a standby in Morgan City, Louisiana, to assess possible environmental damage as soon as the fire is put out. The Mineral Management Service officials said there have been 39 fires or explosions offshore in the Gulf of Mexico in the first five months of 2009, the last period with statistics available. Seventy-nine of the total 126 workers were Transocean employees, six were from BP and forty-one were contracted. BP spokesperson Darren Beaudo said all BP employees were safe.
This photo from a NASA satellite shows the oil slick in the Gulf of Mexico on April 25, 2010.
Although initially the undersea wellhead appeared to be contained, on April 24 it was found that the wellhead was damaged and was leaking oil into the Gulf. Coast Guard Rear Admiral Mary Landry described it as “a very serious spill, absolutely.” BP, which was leading the cleanup, employed remotely operated vehicles (ROVs), 700 workers, four airplanes and 32 vessels to contain the oil.
Up to 1,000 barrels of oil a day (1.84 litres/second) were originally estimated to be leaking from the wellhead according to BP, but they have since adjusted it to 5,000 (9.2 litres/second). Other sources using satellite imagery have put that number as high as 5,000 to 10,000 barrels a day (9.2 to 18.4 litres/second). Estimating the flow is very difficult, as there is no metering of the flow underwater.
However, the slick was estimated, as of April 29, to cover 4,700 square miles (12,000 km2), an area approximately equivalent to that of Jamaica.

What is the PSI at 400 feet below sea level?
In: Units of Measure
The pressure of liquid acting on a container or other body increases at the rate of 1 atmosphere or about 14.7 lbs. per square inch for every increase of 33 feet in depth. So doing the math results in: 400ft./33ft. = 12.121. Multiplying that by 14.7 lbs. per square inch yields about 178 lbs. per square inch at 400 feet deep.
2. Pressure at a certain depth in water
Scuba divers know that as you go down to greater depths, the water pressure increases. In fact, the increase in pressure is 14.7 psi for every 34 feet of additional depth. A diver that descends to a depth of 100 feet must withstand a pressure of …
( 100 ft / 34 ) x 14.7 = 43.24 psi
This pressure is in addition to the normal atmospheric pressure at the surface. The pressure limits the depth to which unprotected divers can go, and the pressure causes lots of problems.
The point is that as you descend deeper into a fluid, whether it be water or air or whatever, the pressure increases. And if you go upward toward the surface, the pressure becomes less.
(Now I know that the pressure at the depth of the Deepsea Horizon leaks is 2,000 pounds per square inch and the three leaks that BP admitted were there have been gushing explosively against that pressure at an incredible speed as seen in the videos.
As it turns out, since we’ve all seen the live feed videos of the top side of the failed blowout preventer – there were several leaks along its surface as well as the other leaks they had originally admitted. In one of the videos there were several plumes coming from another length of pipe as well, and one pipe laying sideways in the first 30-second video clip they released showed a pipe with explosively expelling volumes of crude oil from the 21″ or 22″ diameter pipe exit – my note, cricketdiane – added today, 05-28-10)
(We also know now that BP had this information from the outset and throughout the testimonies they gave and public briefings, etc. At some point and it has not been ascertained when, these live video feeds were also among the available information to the Unified Command which included the US Coast Guard command group, the EPA and other government officials involved.
State officials may or may not have been included in that information access, it hasn’t been discussed yet. Congressional oversight and investigative committees were not privy to that view of the volumes of oil coming into the Gulf of Mexico until 23 days after the explosion when they demanded it – or at what point earlier than that? It has also not been discussed but the major groups of visual information were denied to them throughout the process. – my note, also added today.)

My Note –
Found this banner on the Rigzone website today – Do you believe it after they caused the biggest oil spill in the gistory of mankind as well as the US?
It says they are steward of the environment?
After directly causing this disaster?
Are they out of touch with any sense of reality – or do they just think that if they say it enough times among their colleagues – it makes what has happened not touch them?
Oh yeah – found on the RigZone page – here –

Ocean thermal energy conversion (OTEC or OTE) uses the temperature difference that exists between deep and shallow waters to run a heat engine. As with any heat engine, the greatest efficiency and power is produced with the largest temperature difference. This temperature difference generally increases with decreasing latitude, i.e. near the equator, in the tropics. Historically, the main technical challenge of OTEC was to generate significant amounts of power efficiently from this very small temperature ratio. Changes in efficiency of heat exchange in modern designs allow performance approaching the theoretical maximum efficiency.
The Earth’s oceans are continually heated by the sun and cover over 70% of the Earth‘s surface; this temperature difference contains a vast amount of solar energy, which can potentially be harnessed for human use. If this extraction could be made cost effective on a large scale, it could provide a source of renewable energy needed to deal with energy shortages and other energy problems. The total energy available is one or two orders of magnitude higher than other ocean energy options such as wave power; but the small magnitude of the temperature difference makes energy extraction comparatively difficult and expensive, due to low thermal efficiency. Earlier OTEC systems had an overall efficiency of only 1 to 3% (the theoretical maximum efficiency lies between 6 and 7%). Current designs under review will operate closer to the theoretical maximum efficiency. The energy carrier, seawater, is free, though it has an access cost associated with the pumping materials and pump energy costs. Although an OTEC plant operates at a low overall efficiency, it can be configured to operate continuously as a Base load power generation system. Any thorough cost-benefit analysis should include these factors to provide an accurate assessment of performance, efficiency, operational, construction costs, and returns on investment.
The concept of a heat engine is very common in thermodynamics engineering, and much of the energy used by humans passes through a heat engine. A heat engine is a thermodynamic device placed between a high temperature reservoir and a low temperature reservoir. As heat flows from one to the other, the engine converts some of the heat energy to work energy. This principle is used in steam turbines and internal combustion engines, while refrigerators reverse the direction of flow of both the heat and work energy. Rather than using heat energy from the burning of fuel, OTEC power draws on temperature differences caused by the sun’s warming of the ocean surface.
The only heat cycle suitable for OTEC is the Rankine cycle using a low-pressure turbine. Systems may be either closed-cycle or open-cycle. Closed-cycle engines use working fluids that are typically thought of as refrigerants such as ammonia or R-134a. Open-cycle engines use the water heat source as the working fluid.

Tiber – drilling to new depths
This is reposted – and if you’ve already read it, then please forgive me for putting it here for the third time – but you never know – maybe it will help –
This is from my original post on April 30 – ten days after the April 20 explosion, the April 22 sinking of the Deepwater Horizon that killed 11 men and dispersed hazardous petroleum and toxic chemical dispersants throughout the Full breadth and depth of the waters in the Gulf of Mexico – and before it is over – maybe across parts of Florida Keys along with the full coast and saltwater marshes and estuaries of the state of Louisiana – no telling where all else. And that has now coated the sea floor and filled the water column with massive plumes of crude oil and oil mixed with dispersants as well as having coated the coastal areas in a hundred mile swath and filled well over 30 acres of marsh into a completely dead crude oil thick syrupy muck.

Here’s the point: the pressure at the bottom of the tank in psi is the same as the weight of the water supported by each square inch of the bottom surface of the tank.
My Notes –
I know the oil being pumped under the water is at approximately 5000 feet down, high pressure, irregular surface area likely, and they have been using robotic submersibles –
there are three pipes, they are leaking 210,000 gallons per day / more or less
CNN reported tonight that the pipes where it is leaking are about a foot diameter? is that correct? And, there is a blow-out protector on top of at least one – or what? was it 50 feet tall on that BOP or was that what they said?
on bloomberg last night’s ticker said the BOP was made by Cameron- which I looked up earlier today – no size immediately noticed – will have to go back to find it – (maybe not necessary)
the oil is getting swept by currents and due to its chemical and characteristic nature is floating quickly toward the surface – but, they also admit that they don’t know the degree to which it is coating undersea surfaces in the immediate area
strong current area?
what type of irregularities exist in the surface features?
how large is the flow are under the water – and how tall are the pipes and BOP together?
could something be designed for later after whatever will fix it now – yes, they are already doing that – and it will have to have some consideration in the immediate design.
get me a tanker, a boom rig and about four boats that can withstand the currents and winds without getting knocked around too bad (plus maybe the rover to check it after the actions.)
where could we get it and what industry has it – doesn’t have to be close by but that would be handier.
(I recognize that I didn’t say the “what” of that sentence but I’ve got an idea and I’m not sure if it would work or even be likely to work yet)

alrighty then – first, I need to find what the bottom of the ocean looks like right there and what the immediate ocean currents are in the area – which mean google map maybe and the NOAA satellite stuff or where?
According to GCAGS Transactions, it has an average width of 8 kilometers (km), and a length of 120 km.
From Wikipedia, the free encyclopedia
The Mississippi Canyon is an undersea canyon in the Central Gulf of Mexico, south of Louisiana. According to the U.S. Geological Survey GLORIA Mapping Program, it is the dominant feature of the north-central Gulf of Mexico. According to GCAGS Transactions, it has an average width of 8 kilometers (km), and a length of 120 km.
On April 20, 2010, the Deepwater Horizon oil platform, located in the Mississippi Canyon about 40 miles off the Louisiana coast, suffered a catastrophic explosion; it sank a day-and-a-half later. Although initial reports indicated that relatively little oil had leaked, by April 27 it was discovered that approximately 5000 barrels (208,000 gallons) of oil per day were issuing from the wellhead, a mile below the surface on the ocean floor. The resulting oil slick quickly expanded to cover hundreds of square miles of ocean surface, posing a threat to marine life and adjacent coastal wetlands.

From Wikipedia, the free encyclopedia
A mooring in oceanography is a collection of devices, connected to a wire and temporarily anchored on the sea floor. The devices are current meters to measure the direction and speed of ocean currents, sediment traps to catch settling particles from the water column or experimental chambers, e.g. to measure the solubility of certain substances in sea water. A mooring can be free floating or anchored for some days to weeks (short-time). Long-time moorings might be deployed for a maximum duration of two years. An acoustic release connects the mooring to an anchor weight on the sea floor. The weight is released by sending a coded acoustic command signal from a ship. The weight (e.g. old rail wheels) is unrecoverable. Floaters permit the mooring to come up to the surface to be recovered by a research vessel.
Okay, that would work –

The weight (e.g. old rail wheels) is unrecoverable. Floaters permit the mooring to come up to the surface to be recovered by a research vessel.
Now, to go find the other part – (my note)
I remember there was an accident where the practice field that was covered by a huge architectural fabric came down on the players – I was thinking that was the Dallas Cowboys stadium – but it was the practice field – that is what they need, then drop the architectural fabric like a tent over the pipes using the acoustic weight mooring system (e.g. old rail wheels). Then, they can take a pipe up under the “tent” and fill a tanker with the stuff to bleed off the oil until they can get the other thing built. (cricketdiane, 04-29-10)
(from the article below about the practice field – )
“The no-frills building was pretty much a 100-yard football field with a few more yards of clearance all the way around. The roof was 80 feet high, the equivalent of an eight-story building.”
IRVING, Texas — Whenever a storm hits while the Dallas Cowboys are inside their practice facility, the sound of rain pelting the tent-like structure can drown out conversation. No matter the noise, safety rarely was an issue — until Saturday.
Winds that were just shy of tornado strength, and perhaps stronger, ripped through the roof during a rookie minicamp practice, essentially popping the so-called bubble. Between the falling debris and the furor to get out, special teams coach Joe DeCamillis broke his back and 11 more people were hospitalized.
( . . . )
Just before the facility was flattened, winds were clocked at 64 mph, a single mph shy of the threshold for a weak tornado. However, National Weather Service meteorologist Gary Woodall said a “microburst” may have pushed the wind beyond 70 mph at the top of the structure. A microburst also was to blame for a 1985 Delta Airlines crash at nearby DFW airport that killed 137 people.
“The fact that there weren’t more injuries is rather miraculous,” Woodall said.
Also incredible: An Irving police spokesman said there was hardly any damage beyond the Cowboys’ facility.
“We checked and we can’t find any other damage than this particular location,” said David Tull, an Irving police spokesman. “The nearby area didn’t have any reports of structural damage.”
Before Bill Parcells was hired as coach in 2003, the Cowboys rarely practiced indoors, unless weather was bad enough for them to ride buses to a high school team’s bubble. Parcells suggested that owner Jones build one, and it was finished in time for Parcells’ first season at a cost of more than $4 million.
The no-frills building was pretty much a 100-yard football field with a few more yards of clearance all the way around. The roof was 80 feet high, the equivalent of an eight-story building.
On Saturday, there were 27 players — almost all drafted last weekend or signed as undrafted rookies — working out when the storm hit. Also in the building were coaches, support staff and media.
Overhead lights swayed violently, prompting players, coaches, staff members and reporters to vacate the building. Several people were trying to exit the facility as the roof came down at about 4:30 p.m. ET.
( . . . )
Eatman and colleague Josh Ellis tried freeing Archer but the structure wouldn’t budge. “It was like a car,” Eatman said. Then safety DeAngelo Smith and linebacker Brandon Williams managed to lift it just enough for Archer to squirm out.

My Note –
These architectural fabrics wouldn’t cost $4 million dollars for this function, since the Cowboys and other facilities that use it have to accommodate a structure for it besides and the safety of people must be considered. It is strong enough – it can stay put in the currents – the submersibles can tug on it to put it into place a little better if it is generally lined up right to being with and the pressures on the ocean floor at those depths won’t hurt it any.
It can also be weighted effectively with some number of weights and floater system without having a bunch of equipment having to be attached for nearly nothing and placed across an undulating and irregular ocean floor surface and still work.
– it can work – but somebody needs to tell them about it – how likely is that?
Engineers can then get the other programs done without this continuation of pumping 210,000 gallons of oil per day into the gulf for five weeks to three months or however long their programmed solutions will take
Now, let me see if I can figure out how to get the solution to anybody out there at BP or the whoever might do something with it.
Hmmm . . .
Doing it this way – by using architectural fabric such as the Cowboys practice field used, to tent the oil over the pipes where it is pouring out – the setting of the tent and weighted system for it could be accomplished in less than twenty-four hours. It would probably take a day or two to round up the doming fabric – preferably from some use where its pre-made size could be used intact and not manufactured specifically to this purpose.
Where could that be found along the coast somewhere – what about NASA or the NASA complex in Alabama?
(from the post I made on April 30, 2010 – and then there was a comment or two made on the post with some great additions, including that the idea had even been reposted by someone on the Huffington Post and I’ve placed it three times now – but apparently it still isn’t even on the menu of options that are available for possible containment solutions until the relief wells are drilled or the well is killed in some manner. They could’ve done it in the first place in less than 24 hours from the time it was offered – but there you go, my note today – cricketdiane, 05-28-10 and 04-29-10 reposted).

3 Responses to “Oil spill in the Gulf of Mexico – right now pumping 210,000 gallons per day”
Has anything of this scale been done before?
Look at this-
Someone else on Huffpost is thinking along the same lines:TENT IT!
From Huffington Post:

It is time to fix the problem. Weld together geotextile fabric, hexagonal shape, weighted at each corner with an outlet and flexible hose attached at the centre. The fabric should be several hundred metres across, drop it over the the blowout, with the weights guided to ensure the cloth covers the well. Oil floats, raising the centre of the fabric sheet containing the oil, where it can be syphoned off at the centre outlet via the attached flexible hose. This method means obstructions are covered over and access can still be gained to the well head around the perimeter of fabric which would be raised above the seabed due to the contained buoyancy of the oil (the weights need to be sufficient to fix the corners and hold it down).
Some internet resources on geotextile fabrics- which coincidentally are routinely used in oil spill cleanups.
May 5, 2010 at 4:02 am eI had not read that on the huffington post but it is certainly thinking along the same lines. My thoughts were more like those architectural fabric roofing structures with the strength and flexibility they have and yes, using the weighted lines to place it and hold it where the leaking oil can collect up under its “tent”.
Thankyou for letting me know of that post… It means that the idea could get to them in some reasonably close form from any of us out here in the real world working to create solutions. It matters that the decision-makers who are onsite to stop the oil flowing from the drilling accident get the ideas that we’ve had from somewhere somehow and use it already – because these ways we are talking about doing it could’ve been used already, solved a significant part of the problem already and kept from the extensive damage that is now going to be surely suffered across the Gulf of Mexico and throughout all the wildlife and marine life in the entire Gulf area.
Unfortunately, these ideas are not being used by the decision-makers in the Gulf of Mexico disaster. And, when they start lowering that tower of metal down into the sea, I’m sure they will believe it is done with very little risk as well. But, whether they knock it into the contraption already on the sea floor and tear it apart to make things worse or not – they are risking that it will happen at one mile down in strong currents and extreme sea conditions where they are doing it.
But, there isn’t to be a something else like what we are suggesting, both me and whoever it was on the huffington post and whoever else among all of us that has suggested anything else that could work with less risk involved in placing it.
I really don’t think anyone knows quite what can be done about that exclusionary thinking especially when the degree of a disaster is compounding and expanding by the minute and its consequences, life threatening and horrific. These people making the decisions for what to use in order to cap the oil gushing into the Gulf are doing the same things everywhere they go to fix one of these things. And not one of them live with the disaster they leave behind as a result.
Just don’t even get me started.
Thanks though – see if you can call them and explain how these designs work before they screw up using the other one made like a four-story metal tower. At least they would have another two options on the damn menu.
– Thanks for your comments,
Will look up the link info – thanks so much

My Note – Today – (05-28-10)
There are so many options available today that were not available in the original planning phases for the oil spill and oil disaster response, cleanup, containment and recovery plans that they’ve been using which were leftover from the earlier agency administrations of thirty years run by the Republican administrations and agency heads and serving the desires and interests of the short-term thinking of the oil industry they represented instead of regulating.
The number of copolymer and architectural / geotextiles / nanoparticles materials research and other things of a similar nature have skyrocketed in the last few years. And, none of these things and this information seem to be brought to bear on the current situation. I don’t know how anything could possibly get through to them that hasn’t already been designed or planned at some point for this possible scenario – none of which is working so far except to let the oil get past it, fail to mitigate the oil or contain it, fail to cap the leak and stop it, allow the oil to take over marsh fisheries, fail to prevent the oil from getting to beaches, and has killed massive numbers of animals, birds, marine mammals, marine animals, turtles, dolphins, macro and micro biotic creatures and food supplies for aquatic and shore wildlife. The things they’ve done so far sure has done those things effectively but nothing that they were considered to be in the plan to do.

How could the EPA yesterday say that the water samples on the shore they took indicated there was no problem for the animals? How could they not have samples with the oil that is in the marshes, on the coasts at every high tide and recleaned up again or left where it sits, in the shore waters where it has been found by reporters, journalists, state leaders, citizens, world class oceanographers and marine biologists? How could the EPA – our US specialists on the environment and hazardous chemicals not have told the fishermen and others going out into the ocean areas with high concentrations of oil and chemical dispersants that there are serious health hazards in it that require respirators and appropriate protective clothing and gear, including protection from the fumes?
How is it that on the NOAA site there is a list of a multitude of marine animals and wildlife that have been found dead or dying in a very, very short period of time and there continue to be right-wing pundits, oil industry representatives, oil men and Republican media organizations who act like just a couple birds had a bit of oil on their wings and they don’t know if it has really affected any other animals or marine wildlife? How the hell is that possible? What kind of evil is that?
– cricketdiane, today – just now – 11.44 pm ET
Going to get away from this awhile. I’m still having a hard time adjusting to the fact that our President was taken to a beach that didn’t have the massive crude oil thick and deep covering everything in the marshes and in other shore areas but was at a place with random small dime sized bits of oil in the sand with 300 people staged to appear behind him in pictures as if they had been there cleaning up all along.
Its pathetic that most of America is more concerned about their holiday Memorial Day plans than this and my guesstimate is that about 90% of America doesn’t give a damn nor understand that these are our national waters and our communities and our families and our nation that are as destroyed as a neutron bomb would’ve been on these areas for generations upon generations no matter what we do now. And, the idea that it is important despite it interrupting a holiday – as animals in these areas suffer horrible suffering and tremendously sadistic deaths – no, I’ll take a break before I say anymore.
(except for one thing – that Memorial Day and the blood that has been spilled for us did not give us a free pass to not be a participant in our country’s times of need – the whole thing about “of the people, by the people, for the people” actually does not dismiss our right and our responsibility as participants. Nowhere does it say in our Constitution that if our national industrial complex does something that gets in the way of a holiday – that the holiday takes precedence and priority over an unfolding national, international and historic disaster.)
Now – going to go take a bath for awhile.
