Concrete submarine

Dozen or hundred of order. The guy is completly delusional, and I realy hope he do not take money, it will be a bad wake up for the sucker who trust him.
You have dozen of these vacuum cleaner salesman around the word trying to sell there invention crap. They all end-up miserable in a little room with the wall full of their delirium drawing.
Cheers

I think the world will never notice even right now, just this forum. Don't to worry about that. The coffin still a coffin, Austria or Columbia, lost for ever since nobody ever will notice it.
As for his web-site, if he sell his crap, even with the lengthly warning, he will be in hot water.

Make sure you get a CEM I 42,5 (used to build a "white tank") quality. with a "Blaine" # above 4000. You otherwise have to build up a watertight "thick film layer" to prevent water intrusion.
Water pressure by the soil can be impressively high, btw.

Just a little update.
In 2007 our expert had already 30 years of submarine experience!!! Yeah....:idea:
So, what are we idiots questioning such a professional?

Doubts? Oh, it is written here:

http://www.psubs.org/webforum/Blah.pl?b-fabrication/m-1169910350/

And when it is written, it must be true.

 

Thank you Richard to direct us to the writting of this amazing man,
This is what I read from Wellmer:

"The by far cheapest way i found in my 30 years of submariner "

The guy is born 16.10.1962, in Hallstatt Austria. In 2007 when he wrote this piece of crap he was 45. So at age 15, after 4 years of medical school he went on submarine. So he started medical school at age 11!
He potty trained at what age exactly?

Wellmer you are such a fraud and a liar.
I don't cheer you

But for all the other
Cheers
Daniel

 

Daniel,

potty training still has to happen I assume. when you go through the links I posted above, you´ll see, he just had no time for that!

 

Hi there! me again!

Not for the weak at heart:

http://www.matweb.com/search/QuickText.aspx

Type in :

"Portland Cement with Treated Silica Fume"

1. Tensile strength 2 MPa
2. Compression; 77 MPa
3. Elongation at break 0,02%
   

1, and 3 is in my opinion pretty nasty, unless you're a perfect driver, with perfect equipment.... In a perfect world...

Well, how can a hull be made, without prestressing, in a way, so that there is no tensile stress (or close to none) anywhere in the hull? In any thinkable condition? (Grounding (submerged/ topside), dry docking (even though maintenance-free; scallops like to grow somewhere...)). To avoid the problem with close to no tensile stress, you got to plan for it, i.e prestress it, I believe...? Or not...?

To use Troll, as an exampel of the load a design like this can handle/ take;
well, Troll wasn't built with much prestressed areas, I believe. But reinforced... However; the project was scrutinized with an army of overpaid FEM engineers, post phase. The build phase; it was scrutinized by a little army of civil engineers, all with extencive experience in this game. The tow phase, an army of experienced tow boats/ skippers, crews... The mating phase, same crew... The final tow phase; that same army as last, with addition of all the best of all the former crewmembers....

Believe this;

Nothing was taken easily upon.... Nobody wanted a retake of Sleipner A1...
http://en.wikipedia.org/wiki/Sleipner_A_offshore_platform
http://en.wikipedia.org/wiki/Troll_A_platform

(Some mentioned that NOW, the Sleipner had 8 legs, just like in the myth...).

To compare one of the biggest engineering performances ever done by humans, with a ... eh well; structure that needed max 10-12 men to complete...? Not a too humble attitude? Not that anybody need that attitude, but anybody may be able to learn, something from others; first lesson; repeat this; "I don't know everything nor enough, yet..." Until it sticks. I often use that line... When I stop being curious, well; bury me before I start to smell...

Another thing to remember; even if Troll is strong, they not travelling around with it in a trouble free/ careless/ maintenance free manner...

 

Hey U!!;
Daniel!!!
Steamer!!!

Can you behave? I am a bit curious here, to what, how, etc, so UNTIL I get that info, could we please behave? I'll not place any bet here, but we could buy rounds if our paths cross somewhere down the line...?

Relax, enjoy:

I was delighted by the conclusion of the failure report on sleipner A (contributed by knut) that engineers did not properly understand the underlaying basics - there was sophisication in the methods, well paid egineering teams, but lack of basic understanding of the load case...

To understand properly the use of rebar, pretension, posttension, concrete quality and numbers that you need to put in for calculation, it is important to understand that tension loads and compression loads are very different forces with very different building strategies.

As most basic, in science we do simple experiments, to confirm or dismiss theories. The toilet paper rip-line theory belongs to the tension force behavior.

If you pull toilet paper it seperates - try to seperate it by pushing it - you will see that the theory is not that "valid" for the field it was presented here.

On this forum i see great abundance of "wild theories" that appearently predict all kind of wild things, without anybody making a minimum effort to test any of those theories for their validness in the field where they are postulated. What is needed is basic understanding.

For very little money you can build models of hulls and get a good overview what kind of theory applies and what not.

If you do that for 30 years (like me) you get a very sound "basic understanding" so you finally can have a relaxed idea what is "going on" instead of "seeing monsters lurking in the dark" everywhere.
In my case submarine building and handling "potty training" occured at the age of 15 when i dived my first self built sub at lake Hallstatt (a 1 tonner).

I was critiziced by people who hide behind a keyboard for having a wide experience and studies on fields so different as Physics, Chemistry, Biology, combined with mechanics, marketing, management, three languages, international market development, etc...

True is, exactly the privilege of this "broader education" provides me with tools for understanding things that go far beyond "specialist box engineering" and pull a project like that off. It has frequently be commented that today we tend to be so specialiced that we tend to know almost anything about almost nothing - basic understanding has become a rare good... generalist who can oversee and understand several fields of science, engineering and management are needed.

It has been questions like:

How much energy does a blue whale use for ocean crossing - can we simulate that in a yacht cruiser model?

Why is it, that no long distance surface swimming animal exists?

Is nautilus balesis a "submarine" how can this "shell material" work for 800m destruction depth?! Why does it NOT feature control surfaces.

...that have lead us where we stand today. These are questions that "military sub builders", "boat designers", and other specialists frequently just may not understand as "relevant" and well worth investigating.

This is a lot of "out of the box thinking" - highly apreciated in management and economics - "medival flamed" by traditional engineers, pure snakeoil for the bitter, suceptible of getting tangled in normative third party underwriting processes, - but finally fun and well worth doing it if you are able to perform somewhat in many different fields.

I have offered here many times to share somthing of the (easy understandable) concept part - without giving away too many details of R&D, so if this is a base we can have a relaxed and educated chat i am on...baseline is you can not "share ideas" with people that can not "socialize" properly - but that is "teambuilding" - a sub-discipline of "management" - so i will stop it here.

 

Wellmer since you don not know how to read let me post again your delilusional post.

This is what I read from Wellmer:

Wellmer you are such a fraud and a liar.


I will post this one everytime you will post your stupidity.

 

Ok Paps.

but have you seen the maniac posted only bubbles again.....toilet paper. Sure he understands a lot of that material, he has to wipe his mouth after every second sentence.
But have you seen only one of your questions answered Paps? Which concrete? You will ask that another thousand times, and he will blow bubbles another thousand times.
oh no Paps, no, not with the whip, ohhhh, outch

 

Willy is definitely a dreamer...

You'd think he'd at least get his stuff proof read before posting it to the

world.

 

It appears our friend Willy is quite a good copier too:

“Complex problems have simple, easy to understand, wrong answers.”
-Henry Louis Mencken-

The failure of the predecessor the Troll A platform should give you pause. Instead you are "delighted" that the engineering failed to understand the stringent demands of this service?

 

Submarine Tom, Wellemer is not a dreamer, but he is a copier for sure.
A dreamer don't have his kind of web site and don't try to attract investor. No, Willem is a.....................you know , these kind of people who try to get money with promesses.
A yes I forget, he is such a dreamer that he do not take any responasbility.
Yes he dream with a lawyer who wrote the web warning. Quite a dreamer.
By the way, did you read his last post? he seams under the influance of delirium. I didn't get any sense of whet he wrote. He is like a televangelist who just makes some noises in the mic in set of talking intelligently.
Farting will have the same effect.
Anyway in the wellmer case he invented to put the same noise in writing. That something.
This is a great idea for him. In concrete
