BP Prepares Complex "Top Kill" Bid To Plug Well
shmG excerpts from the International Business Times: "Government and BP officials are hopeful after extensive preparations, but are not guaranteeing that a complex attempt early this week to cap an uncontrolled underwater oil spill from a well in the Gulf of Mexico will be successful. The so-called 'top kill' procedure that oil major BP is tentatively scheduled to attempt on Tuesday involves plugging up the well by pumping thick 'drilling mud' and cement into it. While it had been attempted on above-ground wells, it has never been tried at the depths involved with this spill, nearly 5,000 feet below the surface."
Just nuke the damn thing, it's worked before and surely nothing can go wrong.
Admit nothing. Deny Everything. Make Counter-accusations.
At this point it's pretty obvious that BP is out of ideas - well, aside from a nuke - so maybe chewing gum is the next option?
You know, If I was drilling oil via a pipe that went 5000 ft straight down into the water I'd have made sure there was a pretty much foolproof way to shut the damned thing down before beginning.
Three Squirrels
What could go wrong? All that can happen is that it doesn't work, and then they'll not be much worse off than they are now, besides having exhausted yet another option. ... ...
Or in the case of success with the pipes actually plugged, all that might happen is that the part of the riser (or part of the pipe lower down even) NOT plugged could rupture from built up pressure lower down
Oh wait
Veni, Vidi, Velcro!
You know what I really can't understand ? Why wouldn't there at least be tested methods for this sort of thing? I can't believe that industries are allowed to do things like drill for oil underwater (which is complex and when failure can cost billions USD and human lives) without having set, tested plans in place in case of this sort of catastrophe.
i just want to see how long, or _if_, it's gonna take for the authorities to stick a huge, multi-billion dolar fine on BP.
but it's not going to happen, right ?
the way these corporations learned to manipulate the legal system, the way they're in bed with politicians, is just sickening.
What ? Me, worry ?
There is an oil spill in the Gulf?
does this seem really stupid? They should have smart people working on this kind of thing - the types of people who would be able to take the known variables, plug them into a computer, and predict the results. I'm guessing they didn't do this the first time because the government wasn't all over them, and they didn't want to lose a large reserve. However, this could make the leak much worse.
@This great guy... are you serious? You don't know about the oil leak in the gulf o mexico? If they don't stop it soon, its going to ravage the whole surrounding area.
Let's wish them luck.
The top kill procedure is well known in the oil fields. Pumping mud and cement is what oil drilling is all about.
Of course, at this depth, things may be more difficult. I read TFA and it makes sense except maybe for this part, which sound too much politically correct:
His agency has been working closely with BP staff to "ensure that procedures are conducted in a safe, environmentally sensitive manner and reduce any risk of additional impact," he told reporters in a conference call on Thursday.
Although he used the term "reduce the risk". There is always risk but this procedure seems the most logical one so far for all I know about oil well drilling. So I wouldn't say that "At this point it's pretty obvious that BP is out of ideas".
In fact, they probably tried to save money with the previous procedures they used ;-)
Everything I write is lies, read between the lines.

Then you do what you know how to do and you do it correctly
You keep your batteries charged in the BOP.
You tighten ALL the fittings and TEST them.
You double check everything and write it down, check it again. Stop when you find out you've missed something.
You don't send the crew with the test equipment home before they even start.
You have adequate mitigation strategies and you deploy them correctly.
You ask yourself 'whatcouldpossiblygowrong' and you try to answer the question. You keep the suits well away from engineering decisions.
Just like most man made disasters, multiple fuckups had to happen before the Shit Hits the Fan. This one is just another example of hubris.
Faster! Faster! Faster would be better!
And according to 60 Minutes, when broken pieces of rubber come up which are obviously pieces of the blowout preventer's seal, you don't ignore it and continue, hoping you'll never need your blowout preventer.
Peter predicted that you would "deliberately forget" creation 2000 years ago...
And just nuke the damn thing...
A smal tactical nuke should do the trick...
So what do you do at that point? Remember, the blowout preventer is 5,000 feet down in an evironment where people can't work and there is over 100,000 PSI of pressure on it. Changing it out for a new one is not an option. Neither is disassembling the blowout preventer when it is connected to the wellhead.
So what do you do? Pretty much what they did - cotinue and hope for the best. Because the alternatives are damned few at that point. There is no valve to turn off, mostly because the blowout preventer is the valve. When it was damaged about the only thing that could be hoped for was that a blowout didn't happen because that hope is about all you have.
Which it sounds like is what did happen.
So, are you suggesting we shove Paul Riser into the well head first?
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort.
The U.S. Navy used to have a research submarine that could go down to 2500 feet: NR-1 engineering and research submarine. This sub was recently deactivated, presumably because they've got something better, probably classified.
What kind of resources does the USN have that they could use in this situation? It's certainly more than what BP can call into service...
Leave BP in charge of drilling the relief well. The Navy should direct efforts to stop the gusher, and bill BP for the services rendered. BP will never be able to afford the total bill to New Orleans, Mississippi, Alabama, Florida and Cuba, so the company should be sent into receivership now.
Learn the rules so you know how to break them properly.

So what do you do? Pretty much what they did - cotinue and hope for the best.
Wrong. You stop drilling and eat the $10 million you've dropped on the well so far. If that's not acceptable to you, don't drill off my damn coast.
It should be illegal to say that freedom of speech should be limited.
How about instead of wasting resources giving the world a streaming feed of them polluting the ocean they spend that time and money on actually stopping it.
BTW, the feed for those that like to see loads of oil pumping into the ocean. http://www.bp.com/liveassets/bp_internet/globalbp/globalbp_uk_english/homepage/STAGING/local_assets/bp_homepage/html/rov_stream.html
Really? That's what you do? Ignore it all, continue and hope for the best? That must be why oil companies all over the place are now making emergency containment vessels to place over their undersea wellheads. Ignoring it was the wrong thing to do. It might be what YOU would do, but it's certainly not what I would do.
Pretty much everyone has condemned the way BP has tried to 'save' the well during their attempts to 'solve' the problem, instead of taking a more direct approach, but it cannot be stressed enough. The oil rig explosion was on the 20th April. It's now the 23rd of May. For a company which is in control of, basically a WMD, there should have been contingency after contingency lined up.
No dice on the blow off valve? Next day try the cap, next day try the plug, then the current 'top kill' method; we'd be at the current progress within a week. At the moment it seems BP is making it up as they go along, that may be all they can do at the moment, but it is unacceptable that there was no preparation or protocol for a worse case scenario, which even this isn't. A tanker full of cement and rubber could have been there within a few hours, this is a disgrace.
It's going to be a long time before new drilling is permitted in the Gulf of Mexico, I hope that time is spent drafting up legislation that sets up some sort of oil spill crisis management that has direct authority to intervene immediately when something like this happens. This sort of task absolutely should not be in the hands of people who have such a blatant conflict of interest.
They likely started work on the relief well (which is intended to cap it off) when it became clear that the blow out preventer had failed, a day or two after the explosion.
None of their other attempts have hindered that process, it just takes time to do it.
Nerd rage is the funniest rage.
You fucking plug the well and stop. The last thing you do is act like social psychopaths in search of money at any cost and continue. They KNEW what the consequences were to the environment, the economies of the coastal states in the US, not to mention other countries.
But what the fuck does a BP executive care about a hard working family in Texas, Louisiana, or Mississippi that depends on the ocean for their livelihood? That's right nothing. Saying that is not hyperbole either. If the executives knew of the fragile state of the BOP and continued, they should be put in Prison. Plain and Simple.
Dear God Almighty man. The last thing you do is hope for the best and continue when the consequences of your actions can affect so many many other lives for decades to come. Your plain assertion that they really had no choice in their actions is appallingly offensive.
Of course they had a choice. They could have stopped.
Rats, When I read they were going to "Top Kill", I thought maybe the US finally was serious about dealing with the BP execs. No such luck, alas.
Can you provide a citation for that? It sounds like you are saying they were trying to plug and abandon the well. From what I understand they were running completely different operations intended to prepare the well for production.
I can blame, and will blame, BP for their piss-poor cost saving, PR oriented, and stupid way that they have attempted containment of this problem, but if they really were capping it in response to problems noted in the BOP, then they are much less of the social psychopaths I thought they were.
So what do you do? Pretty much what they did - cotinue and hope for the best.
Umm, I have to say I work on all surface stacks, but if I was the company man in charge - and yes that is my current job for another major (... okay, fine, company person) - we'd shut the pipe rams, bleed the pressure above them, and fix the annular. Changing out an annular preventer on a surface stack is a relatively routine procedure. Close the pipe rams, bleed the pressure off, unbolt the top, remove the annular, cut a new one in half to go around the pipe, replace it, retighten the bolts, retest, and get on with it. I find it hard to believe that they don't have a way to replace the annular with an ROV. The blowout preventer is not a singular piece of equipment. The annular, the pipe rams, and the blinds can all be functioned and replaced separately. If your blinds are messed up, you have to get more complicated and start setting plugs, but anything above that you should be able to change fairly easily.
Apparently 'test well' is the wrong description (this is me being sloppy, I have seen such language in other forums and didn't verify it), but they were in the process of capping it off so that they could move the rig:
The cause of the explosion is not yet known, although Transocean executive Adrian Rose said production casing was being run and cemented at the time. The well had been drilled to a depth of 18,000 feet.
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.
From:
http://www.upstreamonline.com/live/article212769.ece
I think as much as anything, I said "They were trying their hardest to stop drilling" in reference to them wanting to move their expensive machine and you read it as a reference to them being concerned about the integrity of the undersea structure (which I did not mean to imply, but they would have had to do the "production casing was being run and cemented at the time" stuff in order to shut down the well, regardless of the reason behind the shut down, which is what I meant.).
Nerd rage is the funniest rage.
Will top kill work? I don't have the knowledge to know the answer, but http://www.dailykos.com/storyonly/2010/5/21/868490/-Fishgrease:-Booming-the-Top-Kill put an interesting perspective on it.

I've little to no idea of the procedures and parts you wrote of but I think it speaks eloquently to the Scientific American article that points out BP is the only entity with what is seen as viable technology and the know how to implement it. Any forced change over from BP to U.S. government control of the spill catastrophe might interfere with technical management and solution deployment. I would like to see BP made to comply with total transparency and openness as regards all information requirements necessary to fully understand the entire incident.
ideopath @ play
There's a few docs online from one of the oil field "auditors" (the ones that value reserves and help measure risk, advise on investing and so are familiar with the science) and it looks to me from those reports that there's a good chance that everyone knows why the well blew out. The BOPs failing is a separate subject. A BOP are like airbags in a car. They help mitigate the damage, and the BOPs didn't. What it looks like is that the cement job failed, and the design of the pipe in the hole didn't allow for a casing hanger. Start with this document: http://www.tudorpickering.com/pdfs/tph.well.slides.pdf Look at Schematic #3. You'll see the 7" x 9 7/8" (tapered) casing is run to surface, through the 9 7/8" lnr (not run to surface) There is a space and the possibility that the blowout happened from poor cement across the oil/gas formation and then between the 7" and 9 7/8" liner. It would have a free run all the way up to the base of the BOP. This also implies the 7" x 9 7/8" casing is still viable and still has cement plugs in place. If all true, then it also means that this well would have blown out with heavy mud in the casing. For the heavy mud to get down in a large 9 7/8" space with the oil flowing is one thing, as it's being engineered for. For that same heavy mud to get into a much smaller space , the space between the 9 7/8" pipe and the 16" casing (again, look at the red line/arrows in the diagram) with the oil and gas "jetting out" is going to be much tougher. What may happen is the heavy mud goes in, and gets rejected out, and _then_ the call goes out to put in the junk, stopping up the flow partially, and then trying more heavy mud. They've got plenty of mud, so they say, so they'll try this to see what happens.
At this point, and I am talking out of my ass here, I think it's time public funds were applied to fix this, once and for all. Prosecute any and every executive related to this incident, jail them, seize ALL their assets to recover the public expenses, and call it a day.
They fucked up, they neglected to install proper failsafes, and completely failed to plan and execute a proper cleanup. When you screw up this badly, you don't deserve to ever play the business game again. Do not pass go, do not start a new oil scam, go directly to jail and then die.
-Billco, Fnarg.com
The cleanup is always a fecking pain in the arse.
That is why you prevent it from happening in the first place... I also work in the oil and gas business and the whole pile of neglect in the current case pisses me off to no end.
Last week Statoil in Norway had a blowout situation at a rig and the first safety barrier failed. If this had been the system in the gulf of mexico we'd be fucked over here too.... BUT there was a -second- barrier which stopped the problem. They locked down the well and there was no spill.
It is causing all manner of hell for Statoil at the moment though... people are quite nervous ;)
The last thing you do is act like social psychopaths in search of money at any cost and continue.
Yes! I'd rather they acted like a good capitalist business in search of money at any cost and continue.

I devoutly hope this works so we can get to cleaning up the mess and preventing future accidents like this. As an engineer I know what a *bitch* of a job you've got in fixing this mess--good luck!
Sic gorgiamus allos subjectatos nunc
That's rather misleading. BP's failure to maintain proper a double barrier is no more routine in the GoM than it is in Norway. Best practices are best practices. I guarantee every well I've been on offshore has had a double barrier policy at all times. Onshore, in well understood fields, I've occasionally gotten variances to have a single barrier for limited duration completion operations, but it involved a several page written explanation of risk management that had to be signed off by my boss's boss. It would never have flown in an exploratory well like this. Then again, I don't work for BP.
The design of this well had two barriers at all times - the mud and the BOP at first, and the cement and casing and the BOP later. The problem comes in because the faulty cement job seems to have been known prior to removing the mud, generating the single barrier case. (For those not in the industry - the BOPs were a failed barrier, having presumably passed their last test, but the cement in this particular well cannot be considered a barrier at all because it never tested.)
Not to belittle the problem, but 5,000 ft of water is around 2,200 psi. Cold salty seawater would be heavier, but not "over 100,000 PSI".

You ask yourself 'whatcouldpossiblygowrong' and you try to answer the question. You keep the suits well away from engineering decisions.
Yeah, like NASA during the Apollo era.
The higher the technology, the sharper that two-edged sword.
So what do you do?
You stop drilling until you have found a way to get a new blowout preventer installed. That may require abandoning this well and drilling a new one.
Maybe that will teach them to take user interface issues more seriously, since the root cause seems to have been that billions of dollars could be lost by just touching a joystick the wrong way, without confirmation.
Pretty much what they did - cotinue and hope for the best.
Wrong answer.
Punishment should come in the form of criminal indictments against the persons responsible.
The fact that they are paying, however, isn't punishment (that would be ineffective), it's simply a reflection of the cost of doing this kind of exploration. If that raises the gas price and causes people to switch to other energy sources, then externalities have been accounted for and economics has done its job.
You pull the drill string out, you do a top-kill with thick mud, like they are trying to do now, you fix the fuck-up seal, and go back to work.
Apocalypse Cancelled, Sorry, No Ticket Refunds
They were preparing the well for production use by removing the drill and capping it. It's _COMPLETELY_ different from "trying their hardest to stop drilling".
Emergency shutdowns do not usually involve removing everything that keeps a well from blowing out, so your description isn't just badly phrased; it's also completely wrong.
Removing the heavy drill fluid is a dangerous operation that depends on the BOP for last defense. They did not have the last defense.
- These characters were randomly selected.
The first thing to do was a few steps before that, don't leave the joystick enabled when they are closing the valve for a test. Next is to come up with a way to not bet millions of dollars on a single failure. For something that important, shouldn't there be more than one valve? Then, if one fails, close the other and put in a replacement.
What you do not do is continue and hope for the best, look where that left them.
I listen to American 60 minutes through the podcast audio edition, a quick Search brought up this clip http://www.cbsnews.com/video/watch/?id=6503436n&tag=contentMain;contentBody
What an absolutely harrowing experience. The mention of light bulbs brightened before popping, computer screens blowing out, and then 3 inch thick steel "fire proof" door being blown off its SIX hinges by the sudden explosion...pinning one of the survivors. To escape from this situation, to jump into the water, and risk being burnt by burning oil on the surface...just awful.
It sounds like there were failures on multiple levels, but perhaps all caused by drilling through a rubber seal?
I wish the people working to fix this the best of luck

There's a word for people who think a corporation is some kind of bottomless pit from which you can plunder as much wealth as you want. I can't think what it is right now ... no, really ...
If you fine (or tax) a corporation, it just means the customers and stockholders get shafted. The corporation just passes the cost on. If it is a bad enough hit, or if they can't pass it on, they go bankrupt. That'll really help the situation ... NOT. And if you think stockholders mean a bunch of greedy billionaires, think again. There are countless little guys with 401K and IRA funds in that stock.
You can find individual corporate officers guilty of criminal negligence, however. This won't help all that much with paying for the damages, but will make a lot of us feel better.
But yes, the corruptocracy which is a collusion between government, bureaucracy, and megacorporations is sickening.

Shafted? That's nonsense. There's no easy way to say this, so I'm going to just lay it out for you. If you buy stock in murder, you are a murderer. Those who held IBM stock during the holocaust have to take their share of the blame, because IBM built the concentration camp management systems. Those who work for BP must take their share of the blame; every employee of BP shares in the profits, therefore all of them must share the blame. Why should BP's stockholders be any different?
If it is a bad enough hit, or if they can't pass it on, they go bankrupt.
Good.
That'll really help the situation ... NOT.
Your snarky sarcasm doesn't change the truth; permitting the same cast of characters to do the same nefarious shit again and again is the alternative. We must invoke the corporate death penalty on those corporations which deserve it. The people the corporations are made up of have a choice — they elected to go to work for a planet-raping corporations too irresponsible to even clean up its own messes, and they deserve no quarter from any right-thinking person. Every shareholder is just as guilty as every BP executive, no more, and no less.
And if you think stockholders mean a bunch of greedy billionaires, think again. There are countless little guys with 401K and IRA funds in that stock.
Greed is greed regardless of scale, and investing in a corporation known to do truly disgusting levels of damage to the ecosystem is just another expression of greed. There's plenty of nature-friendly investments they could make. Might they make less money? Sure. If that means they have to settle for a truck camper instead of a diesel pusher RV for their retirement, so be it. But if your argument is that people in rich countries should face no penalty for investing in the destruction of our ecosystem, you're making a morally bankrupt argument. When you invest, you're putting your money to work, and you have a responsibility to make that investment... responsibly.
But yes, the corruptocracy which is a collusion between government, bureaucracy, and megacorporations is sickening.
Corporations and governments are made up of people. Without those people they don't exist. Shareholders are critical to a public company and without them the corporation loses its ability to do evil. Ditto for employees. Therefore, the shareholders and employees of BP are evil. There's no two ways about it. If you work for big oil, you're fucking scum, even if you're one of the people who is there to contain spills, or prevent accidents. I don't care if you have to feed your family. If the price of your family's continuance is oil spills which have severe repercussions for the continuance of the entire human race, then it is both illogical and immoral to keep them going. You do not have an inherent right to life; we all die. Why should oil companies be permitted, however, to hasten that for all?

So you've killed a paper document. Burned it in effigy, perhaps. Great job. Now, total demand for product remains the same. Other companies are going to need to hire folks to handle the increased volume. Conveniently, there's a handy pool of experienced folks ready to start screwing up their new employer.
You plan has no real world effect whatsoever other than temporarily feeling good, rather like a drug. And some rich lawyers will get richer by shuffling some papers, but thats just business as usual.
Now if you personally ordered the death penalty for those whom were the cause (assuming they're not already dead from other causes, etc), then you'd at least have a measurable positive effect. But environmentalists never quite have the guts to pull the trigger, they always want someone else to do the shooting, and someone else to catch the bullets. Nothing but a call to arms for the nameless and faceless "other" (usually the government) to kill the nameless and faceless "other" (anybody other than me and mine). I'm unimpressed.

False. People will think twice about who they go to work for, creating a competitive advantage for more scrupulous companies. I don't think it's a complete solution; we also need to take the money needed for the cleanup away from the companies that made the mess. In this case that seems to mean Halliburton and BP. Make it unprofitable to make this kind of fuckup and the companies will stop doing it. I maintain that destroying corporations and forcing their employees to seek other employment will make employees of other, similar companies more scrupulous. It's the belief that "it can't happen to me" that encourages malfeasance.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
This about this for a second. The corporate executive officers at BP--even those at quite modest management levels--probably didn't(and still don't) know what a Blow out Preventer even was. I doubt they even really understood what oil is, apart from being a black liquid worth lots of money. If you tried to explain to them what a valve was or what it did, their heads would likely implode.
Ignorance is a great defence in the face of charges of negligence.
May the Maths Be with you!
Ummm, this was already tried.
Thats what the containment dome as all about.
Good post. If I had any mod points you'd go up.
You are right about multiple fuckups, a single failure isn't usually the problem.

I understand it is pointless to debate a fanatic, but I will just add this for the benefit of people who have an operating sense of proportion.
A guy with a 401K or an IRA is very unlikely to hold stock in BP directly. He holds XYZ mutual fund, which in turn is invested in BP and in dozens or hundreds of other corporations. The guy has better things to do with his time than investigate every one of these corporations in depth and find out which ones some fanatic regards as murderers, and then try to find a new mutual fund which his investment plan allows him access to which includes none of those. You should not be surprised at this.

You should not be surprised at this.
There are such things as socially responsible mutual funds, so this is a bullshit excuse. All it takes is the desire to go find one, and the ability to use a computer. I reiterate: if you hold stock in murder, you are party to murder, no matter how watered-down or abstracted. You are a financier of murder. Voting- or non-voting, whole or fractional, murder is murder. Or, you know, insert_offense_here. If you own Sony stock, you've financed rootkits. If you own Microsoft stock, you've financed anticompetitive practices. Pick your proven corporate offender and put their name into the sentence if you find these examples unpalatable or irrelevant.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Yes there are so called socially responsible mutual funds. One man's socially responsible is another man's irresponsible, or even pandering, but that's not the point.
The point is that with a 401K, you are limited to the firm your employer offers you, and the mutual funds that firm offers; and to a lesser extent IRAs are effectively limited too. I am more in tune with your feelings than you might imagine, but this rhetoric is so over the top as to be nonproductive or even counterproductive. Murder? How did we get from an oil well accident to murder?
But... But... there was an executive BONUS at stake - if the plugged up the well some poor BP exec wouldn't get his bonus! that is completely unacceptable, better to take their chances that everything would work out.....
My father worked 20 years for BP and is an oil safety expert - after a few conversations with him we come to the following - The only proven solution to a spill at this depth is to drill a secondary well to extract the oil. This unfortunately takes 8 to 9 months. Why not drill the secondary well prior to extracting any oil from the primary well. Then in the event of an accident such as this - you can switch to the secondary immediately and not have slicks for 9 months. The only reason is cost...
BP failed to do any kind of accurate risk assessment with this well, if they had done this they would never have drilled in this location at this depth, then they had a faulty blowout valve, that they knew about - they ignored the risks. They should pay in full. I have no sympathy for BP at all.
Next time they should consider placing two blow out preventers, one right after the other, just in case the first one fails.
Top Kill is the final culmination of research on what was previously known as Mud Bomb and was simulated using sophisticated software code named "Scorched Earth".
I think you underestimate just how much I just dont care.
Well, that's because no such technology exists. So you simply make failure impossible via paperwork. You need a perfect cement bond job, so you require one. You need a perfect and tested BOP so you require one. The odds of both failing at the same time are astronomical. Which, as you can see, does not mean its impossible, just very rare. I suspect we'll never see an identical failure, its just too unusual. Oh we'll see other failures, just not exactly like this.
vlm: You misunderstand how safety engineering should work. It does *not* depend on any one technique being "perfect". Proper engineering would anticipate almost every failure and have a way to deal with it (again not perfect, but maybe 99.9% reliable). I am an electrical engineer (not an expert in drilling), but here is what I would do:
1) Have multiple wellheads already in place in case everything goes wrong with the blowout preventer on the active wellhead. Have an extra riser pipe ready in a nearby warehouse, to connect an alternate wellhead, and relieve the pressure in the damaged wellhead. Note: this does not require drilling multiple wells, just extra piping to the alternate wellheads.
2) Have several emergency cutoff valves at various depths in the well casing. These should be of such simple design that failure is almost unthinkable, and they should be tested at least once a month to ensure that they will work.
3) Re-design the blowout preventer, so there is not a situation where a single failure could make all redundant systems fail simultaneously. That is my understanding of the current failure. It all happened because one bozo pulled the wrong lever at the wrong time and destroyed the one valve that would work with the drill pipe still in the bore.

This came from radio-canada, so no links, sorry.
