Diving bell boat: Walking down to the Rhine's riverbed
Vložit

- The diving bell boat "Carl Straat" patrols the stretch between Alsace and the Netherlands. Captain Thomas Bach keeps the riverbed clean. His ship features a steel diving bell that can be lowered, using overpressure to displace the water at the bottom of the Rhine. He can then stay dry while working below the water; retrieving lost anchors, for example.
For the crew, it is a seven-meter descent via the shaft pipe to the bottom of the Rhine. There they have to work in very harsh conditions, from compressed air to extreme heat in summer and cold in winter.

This thing is 50 years old and I had no idea of its existence. Incredible technology.
Makes you wonder how much technology the government is hiding
I'm 49 never heard of it,would lv to go down walk around
I had no idea this kind of thing existed, but it makes sense. It's essentially a mobile caisson. A great book to read is David McCullough's "The Great Bridge" about the construction of the Brooklyn Bridge. The foundations for the Brooklyn Bridge towers were made in a similar way, with caissons sunk to the bottom of the East River, pumped out with compressed air and men within them directly digging out the bottom of the river. Many died of compression sickness, which was not understood at the time.
@@cv990a4I wonder if they have to decompress coming up from this?
Is really no technology at all.
Turn a glass upside down and sink it into the water.
If someone had told me that such a craft existed I wouldn't have believed it.
You ought to see how they weld pipe underwater a different type of diving bell but pretty much the same principle
Right? there's a ship that lowers a tunnel in the water and pushes air in and the water is pushed out and you can go down the stairs in the tunnel at the bottom of the lake . Yeah right... sure...
Innit

What’s impressive is that this isn’t a new process either. They’ve been doing this since the 70s
This needs to be a tv show. This i'd watch
At least a CZcams channel documenting the stuff they find
Totally agree!
Absolute
Isn’t CZcams amazing? 💛
Same ❤
The fact to put your feets on a piece of Earth where no one before was, must be amazing every time.
Not necessarily, maps show that the romans settled there in 800 BC and between then and 1000 AD drained a lot of the peatlands. Its moved under human influence. Both the beginning and the tail.
@@Laura-wg7mgLook everyone it’s A FUCKIN NEEERD!
I do that in my backyard in Texas every day
@@Laura-wg7mgalways one. Any need ? You know what they were meaning but you couldn’t leave it at that. Wow. Its not a competition.
The path of rivers aren't constant. Of course, well-managed waterways like present Rhine changes very little, but before large permanent settlements, the river went where it wanted.
Am i the only one imagining how this would be if @tomscott did one of his legendary single take about things we might not have know.
Oh no, you don’t know do you?
I’m surprised he hasn’t actually, this boat is right up his alley. Too late now I suppose
@@xploration1437 I'm just lamenting... hope he is enjoying the long overdue Vacation!
Come back to us Tom!!!!
He's a racist. Why would you support a racist?
Thats why we like to watch CZcams, for genuinely interesting videos such as this. Fascinating.
EXACTLY! 💯
I can see how that job would never get old! Remarkable how the pressure changes cause fogs to suddenly develop. This could easily be a whole documentary following them for a year. ❤
This Thomas Bach is doing something useful - not like the other one....
It would be more interesting than all the other reality show garbage on TV, and therefore not very popular.
.
What a brilliant concept. I would have never believed the river bed would be so dry for walking on.
Table and chairs, sandwiches and beer. A picnic on the bed of the Rhine! A tourism opportunity. 😊
Except for the part where it makes you tired very fast.
If it was a glass bell, that would take off....
@@halberderdier8073the Rhine has zero visibility so there would be nothing to see.
@@teeanahera8949 -- Agreed... It would be like having a picnic in a round brown room...
@@TheNefastor Indeed, but so does having lunch up on top of Mt Titlis. 😀
Diving bell boat "Carl Straat" was retired Sep/2021 and replaced by its successor "ARCHIMEDES". You're welcome.
I hope, the "ARCHIMEDES" has some kind of air condition for the air in the bell. We could use a ship like that on the Danube river.
As a archaeologists this is a dream. Dam you could fill a museum with that tec..
Roman helmets, mp38s, Iron age coins the list is endless..
Mp3 players, old beer cans, lost keys, a ring...
They mentioned the abrasive effect of the tumbling rocks, it probably results in any ancient items being ground to dust.
I never imagined that the diving bell would so effectively displace the water. I figured there would be at least knee high water to contend with.
I think it has like a rubber seal and any of the water trapped inside the bell as it sets down simply flows away through the gravel
Compressed air is pretty strong. I think if the bell weren't pressurized some water would force its way in until the atmosphere was compressed enough to resist it, so by making that pressure beforehand no water gets in.
Use a hollow bottle with a big open wide mouth. You will be able to demonstrate this ability. Trust me as long as you maintain pressure inside without moving the bottle too much the water won't get in not even an ounce. Not a drop. The moment you lose pressure it goes in.
Tell us you didn't do well in science class without telling us.
Wow I would have imagined the bottom to be mud. Great video thumbs up.
Well the closer to the Netherlands you come the more mud will be on the bottom
That is fascinating-I've only seen it in rock strata and of course small shallow streams. In the study of Sedimentology (Geology) that part of the sediment in a stream is called the Traction Load, which bounces (through the process of "saltation"), and also rolls along the bottom along with the current. If the current is swift enough, smaller sized particles will remain in suspension as the Suspended Load until dropping out in slack water forming sand bars. Very fine (mud) particles are called the Wash Load and they don't settle out in the stream at all and will stay suspended until finally dropping out, well out into the sea.
Fast flow = no mud. All the sediments are being carried by the water. Even the stones on the ground are rolling.
Slow flow = sediments sink down and we get mud.
The interesting part is: Where's bed rock? Where are the edges that collect the big nuggets?
Very cool! I'm impressed at how steady that ship can keep itself in position.
Lived on the Rhine as a kid and had no idea this existed, so cool. What an interesting job to have!
Never seen anything like this. Amazing piece of machinery, genius engineering!
That's crazy, i never considered it would be possible to use a driving bell in this way...genius!
A mudlarkers dream job. The history you find while salvaging has to be one of a kind.
And the treasures
@@hugoagogo4324 -- Old corroded beer cans... Some of us can remember when beer cans were made from steel...
Wow! Do they have their own CZcams channel? I would love to watch every adventure. I bet they find such cool things. I want to know what they did with the bomb!
I guess these guys are the original "Rhine Stone Cowboys" ---- not my quote but I had to pass it on!
😅😂😂
Thank you for your service.
The Rhine has had humans crossing it for thousands of years so it would be fascinating to find ancient objects like swords and such. Incredible boat!
Who has came from Instagram reel 😅
I came from LinkedIn, where much instagram stuff is plagiarised these days, in the name of business!
No
Me lol
No.
Me
I would watch a full 8 hour shift of this boat quite frankly. Please make it so.
A rare video that is exactly what I hoped it would be from the title.
This is one of the best jobs I could possibly imagine.
Als direkter Rheinanwohner für mich ein absoluter Traumjob. Für andere vielleicht nicht nachvollziehbar aber immer wenn ich am Rhein bin frage ich mich was wohl gerade alles im Flussbett treibt. Selbst am Ufer finde ich immer wieder Dinge aus aller Welt. Faszinierend! Toller Beitrag Respekt an die SchiffsCrew❤
What a fabulous invention! What a unique occupation! Setting foot where no one has before...indeed!
Not a new invention, diving bells with air pumped down were used in the 1800s.
Now at last a decent yt recommendation. Thanks amazing
That is freaking amazing to see "dry" rocks at the bottom of the river like the Rhine. I'd be treasure hunting my @ss off if I owned that thing!
That is so interesting. I could watch this type of programming all the time. No garbage reality stuff, just things that educate you.
Wow ! What an amazing machine ... Its so cool that you can go and have a walk around on a river bed !
Mel fisher should have bought a ship like this ,for the treasure coast of Florida, to recover the 1715 treasure fleet ,beyond impressive, simply incredible, wow genius.
That is absolutely incredible. I would give almost anything to work on a boat like that.
wow.. i live near the rhine and never knew this existed. That's amazing 😊
I can’t believe they don’t use these for archeology.
Wonder how old that plate he picked up was
it said Ikea on the bottom. Late Viking I guess. @@onemoredeadman
They use a somewhat similar thing for archeology, where they drive a huge steel tube vertically into the water and several meters into the river/lake/sea bed, then pump all the water out. A couple years back the Dutch Navy did it in the middle of the IJsselmeer, during WWII a British bomber had gone down there and they wanted to recover as much of it as possible and give the airmen a proper burial. It's pretty crazy seeing the pictures of that bomber laying there in the mud, it's engines and propellers still clearly recognisable.
Probably not economically viable. This thing will cost thousands of euros per day to run.
Very clever Germany, awesome solution, well done.
Beautiful machine and beautiful science. I'm always at awe at the marvels of human ingenuity
A truly fascinating video! I’ve always been interested in the Rhine as an International Waterway and have travelled along several sections ….but I hadn’t heard about this special vessel! Are there others like it on the Rhine? Thanks for a truly informative programme. Rob in Bournemouth, England.
Extremely interesting. Thanks
If you marketed this to the super-rich as an exclusive experience of having a lunch on the bottom of a river or shallow sea, I bet it would catch on
It would have to be a very shallow sea, as spending enough time on the bottom to have lunch would require decompression stops on the way back up if it was too deep.
Don't give then ideas..... you know they will just suck more money out of everyone else to do this
@@delboy1727 Not unless they get wet! If the pressure is kept at around 15 psi they would be fine.
They seal that bell by keeping the air pressure inside slightly higher than the pressure of the water outside. Therefore the deeper they go, the higher the pressure inside the bell needs to be to keep the water out. 15psi is the pressure at 1atm, i.e. at the surface. If the bell went down to 20m, the pressure inside would need to be at about 45psi, otherwise the water pressure outside would be enough to flood the bell. I believe that bell only goes to a maximum of 10m so the pressure inside will only be about 30psi to keep the water out, but even so their work time is not infinite, as even breathing air at that relatively low pressure will still lead to a build up of nitrogen in the blood stream.
@@delboy1727 But decompressing with a high oxygen atmosphere works fairly fast for the pressures even from equilibrium: you can pretty much just give them 1 normal atmosphere of oxygen to let them breathe off the nitrogen, slowly dropping total pressure down to ambient, and give them a bit more of the high oxygen to deplete their nitrogen further. The oxygen bound to your red blood cells increases the maximum O2 partial pressure you can have without getting oxygen bubbles, so mild oxygen-only decompressing is actually totally safe.
Wow...that's incredible! Truly surreal.
Absolutely fascinating!
That is such a cool piece of engineering. Imagine the artefacts they must find, too !
Fascinating. Thank you!
That was an awesome video, thanks.
This is such a great design how have i not seen more of these around the world.
It only works in relatively shallow water 7 m in this case so it’s not suitable for anything much deeper. The workers would need decompression if it were deeper and therefore much higher air pressure.
Amazing video!
We see it! 😀 Fascinating too. I’d never heard of a diving bell before now. Keep up the good work Tomas Barh.
Thank you for posting. I can cross that off my bucket list without having to go down there.☑
How incredible is this.
Very interesting! Thanks for sharing!
Great work lads
This is one of the coolest things I've ever seen.
Super interesting! Never too old to learn 😊
Ok, hands down. That is the coolest job i have ever heard of.
This is awesome!
Spectacular technology, wonderful ability and truly amazing!
This is like pure science fiction 😮
Imagine what you could find around the world with this kind of boat.
probably the coolest thing I have ever seen.
Amazing, never dreamed of such a boat
Fantastic! I never knew that vessel existed.
This is amazing. Imagine going to work and walking on the river bed of the Rhine in ordinary clothes .
This must be the perfect Discovery series; Recovery at the Rhine.
Brilliant piece of Engineering.
This is so badass! I love it
Amazing piece of engineering 👍
That was amazing 👏🍀
Sehr beeindruckend!! Hab nie gewusst das es so etwas gab... Und ich leb schon fast mein ganzes Leben nah am (Niederländischen) Rhein! 😎👍
Der Shiff ist absolut interessant! Ich hatte keine Ahnung dass it existed. Learn something new everyday. 💯💯
Simply awesome 👍
I want one so bad. I thought maybe they'd be sloshing around ankle deep but no, as dry as the shore line, incredible.
I'm surprised at how undirtu the Rhein is here. I expected a mud bed down there, but you could almost have a picnic!
Very interesting, I wasn’t expecting a stoney bed!
Blowing my mind
Incredible machine.
That was very interesting. Thank for sharing this with us :):):)
this seems like it quite literally is the most dangerous job in the world
the ship was 60+ years in service without a single life lost on the job ... very far from the most dangerous job. statisticly its the safest job so far, lets see how well the replacement will do.
You are, quite literally, wrong. You also don’t know what the word ‘literally’ means. The divers at the bottom of an off shore oil well that got sucked through a 5cm hole would have disagreed with you too.
Fantastic!!
Such cool tech, like things we dreamt about as children!
wow this was really cool to see
Interesting AF. Thanks!!
I have worked with hard hat divers and saturation divers… but never even imagined such an operation as this. This is like a floating, mobile caisson. ¡Humans are awesome!
Sehr interresant! Very interesting,I would like to see more of their work!
That is such an amazing piece of technology.
Fascinating.
Amazing!
What amazes me is that the floor is so solid... not mucky or soft at all...
What a cool craft. Would love to experience that
This is so cool. I didn't even know it existed!
incredible!
great stuff
An important question remains unanswered: did they find Das Rheingold? Is it true that cam be forged into a powerful ring?
The Rheingold remains elusive. But you can see it twinkling in the sunlight at the Lorelei.
That's pretty cool! 👍🏼
what a trip
So cool didn't know you could walk down to the bottom of the river
Very cool, special case tool
That is so awesome.
I’d love to do this!!! Imagine the things they see and find.
What an amazing thing.
