Back in the 19 60’S my ship was cut in half to give it an extra hatch, this was preformed in John browns yard of Glasgow, the ship was the crystal sapphire a bulk sugar for Tate and Lyle, the owners ,Dagenham Dock London.
Such a clean cut.... Amazing !!!
Very impressive, large scale precision...
wow! From San Diego, CA USA, how VERY INTERESTING. I never knew this was possible. I am very impressed
Amazing feat of marine engineering.
Thank you for sharing. Good video. Excellent education and entertainment for a bunch of us who sit at home never to experience such challenging duties.
Great vid. Could you shoot a vid on the working of a draw bridge, the gears working as it raises and lowers?
Very good educational video.
Could they use laser shining one side to other to confirm separation, along wit visual inspections?
I highly recommend the diesel additive for cleaning called ‘Fuel Right’. Top product.
Amazing
Would it be possible to use strong electromagnets in numerous places to keep the joints tight together for welding
Unreal!
What i find even more remarkable is how they are able to find and disconnect all the pipes and cabling!
Yeah... because the entire structure is an absolute mystery.
@@Katchi_ Not so much that, there are detailed plans after all, but actually making sure you have found and checked everything! Imagine you forget ONE cable...
For sure.
Drinking game - take a shot each time they say "Jorg Palantin".
How about when anyone says ship or ship's?
I came up with a simple way to check if the original ship has been splitted into two pieces completely without being connected even a centimeter long. That is to check if a piece of string or wire can be moved through the entire cross section at the cut.
This is like a PBS documentary for 6 year old children in America.
Please do not discredit six year old children.
I take it you are a Know All
BC ferries have been doing this for years. Both length and height enhancements.
What an amazing video and such skill by all. I'm a little surprised at the lack of PPE and edge protection 😂
They don't need PPE, they're sensible, professional men who recognise danger.
Everyone looks like they are very well fed.
Fat one's 😊
That's why they need bigger boat / vessel. Video wobbles and even sound sails around, so it's like nightmare some point.
And they say only Americans are fat.
How do they weld underneath
Some job satisfaction there
I just cant imagine those welds being as strong as the old ship??
The entire vessel is already welded together like that from birth.🤷🏼
That used to be a problem with the old WWII 'Liberty' and 'Victory' cargo ships. Every so often one of them would snap in half, if we recall, in the same general area every time. Something, something, brittle steel. Was solved by attaching metal 'straps' to the sides of the hull to take up some of the stress.
How they built in the first place??? 🤦♂️🥴🥴🥴
A correctly welded joint will be stronger than the surrounding material, once welded the operator will have all of the welds checked with a electromagnet that with the use of a ferric spray, and after a detector will show any imperfections in the weld that can be investigated further. It’s not their first rodeo and won’t be their last either.
@@chezsnailez these were ships built in weeks so theres going to be defects and bad workmanship on some causing them to snap and fail. the Liberty class ships pretty much won the war as so many of the dam things were built. an absolute super human effort to build so many in such a short time
I, too would have preferred to have seen some of the actual work during the cutting and rewelding.
What a big job
2:02 Interviewer “Are you nervous? Project manager. “No.” Says the man with armpits so wet it looks like he’s been in the rainforest😂
I'm an Australian and can remember the pain of farmer's here in the 60's that lost their British market. I can't not appreciate the irony of what is now happening.
Merry Christmas everyone from Australia 🎄 🎅
Yes editing can make anything look easy however this speed of turnaround: shows impressive organisation and preparation. When a "stretch" is both horizontal and vertical the extra windage with the same power installation can (as experienced) challenge manoeuvrability in severe wind conditions.
35 days is very fast until I found out the South Koreans build an entire 800 foot bulk carrier in 34 days.
@@thereissomecoolstuff Building a vessel is actually simpler and faster because it requires less time in the drydock
@@alex9621 I agree with you. Dry docks on their own are amazing. Boeing is making 1.3 737 a day trying to get to 1.8 per day. We live in an amazing time.
@@thereissomecoolstuff New building is always faster than conversion !
@@IntheFishtank I agree. Imagine an entire modern ship from cutting steel to launched in 34 days. Until any modern country can do that we will be at the mercy of those that can.
What a pitty that a link to the original german Video is not in the description of the Video yet!
Astounding incompetence for both the ship's crew and the dock workers. Seems to me that emptying the diesel tanks would have been done if a sharper organizer was in charge.
Found the ignorant entitled ameritard...
It may look easy??? Nooooooo. It definitely doesn’t look easy!
I would think the hardest part is match the insert to the original ship. I would assume the blueprints would specify dimensions and spacings of the hundreds of stringers that make up the various deck floors and overall dimensions but I wonder if precision spacer blocks are used to help to position certain multiple members that are tacked to metal deck sheets to form various quite precise components.
I would like to know if they use a "C P T" ( Critical Path Technique) on this kind of job ?
Just me or does the video look "wavey" no door frame is straight, just looks strange
British Pedant Here. There is a difference between cutting a ship in half, and cutting a ship in two.
Fascinating heavy engineering excellence showed. Sad to see the chem-trailing overhead at 40.48. and other outside scenes.
Presumably, you mean aircraft condensation trails. Why is that a problem?
Ah, yes those mysterious condensation trails, indicating the unknown science behind Archimedes of Syracuse' steam engine.@@davidelliott5843
Are you implying that airlines are poisoning our atmosphere on purpose and to what end? Have you analysed those trails yourselves and found proof that they are full of detrimental chemicals.
Opening VO all about giant container ships. Actual vessel, a big car ferry and the work was all done years ago, and has already been gone over in at least two other docs. Has no other ship gone through this?
Too much of talking heads and contrived suspense and too little about technical details and the actual procedure. An interesting project video made boring!
Indeed al bla bla bla
Not only too much taking, the music is also unnecessary.
It’s probably a trade secret? I suspect not many companies in the world could tackle such feats🤷🏻♂️
Thanks for saving me an hour
The commenters, what a bunch of dorks. Yeah, if you were in a train or car wreck, would you be talking tecnical details. They are in survival mode. Being able to acquire fuel is an accomplishment. Trying to ascertain the "why" mid ocean is a wasteful activity. Getting to shore is the immediate concern. If any of you want an inspirational message...read the bible😅
In my 35 years in Ship repair, at Middle Dock Engineering, UK, we cut numerous Ships in half and lengthened them. It is not a big deal. The outstanding job for me was when we cut a Ship in half horizontally and heightened it by just over a metre. It was the first time it had been done in the World. British skill at its best.
How thick are the steel shells.
Are they hand welded, stick welded.
Cool!
😅
BK British Knowhow.😅😂a JOKE
Seeing the severed section at the base of the hull, that definitely was single skin, not double skin, as they mentioned in the video
Correct, it is nothing but single hull. Even the Class classify the vessel as single hull, so go figures.
I think they meant it had a double bottom.
Why extend a ship if the guy described it as unstable due to it's design?
What so they just completely skip over the welding process. That was the one bit I wanted to see.
Yes i arge
52:08 bit of scruffy welding on them butts
Carry extra flares.
‘those butts’
Damn ads.🤬
They done it to Bell ferry ships, they all foundered
I had serious anxiety when they were walking in-between the halves!
As much as it pains me to say, you have to admire their efficiency. There is no way on this earth that a British shipyard could complete this type of work in 5 weeks. They would spend longer than that just drinking tea!
I have seen KZhead videos of extended ships where the bow is flexing up and down in rough seas and one where the bow broke off. Not German shipyards though.
I sailed on this ship as a passanger from Ghent to Goteborg a few years ago.
Would that have been before or after the extension?
@@badad0166 After, in 2018. This video is over 10 years old.
@@Bob.martens Thanks! Sail On!
you only sailed on a part of this ship though....
Vraagje als je allen schepen op de wereld uit het water haalt, hoeveel cm zou dan de zeespiegel zakken?
We are talking about approximately 55,000 ships, of which approximately 770 are supertankers. A reasonable estimate is that all those ships together are comparable to 5,000 supertankers, each 300 meters long and 50 meters wide. This gives an area of 75 km2. These ships have pushed away water over this surface, with an average draft of about 20 meters. But if we spread that 20 meters over the entire ocean, it is 'diluted' by the ratio between the 75 km2 of the ships and the 360 million km2 of the oceans. This results in an increase of 4 x 10-6 m. So those are not centimeters, or even millimeters, but micrometers! For comparison, 4 micrometers is about one-tenth the thickness of a human hair.
Great show, very interesting, but at the same time SUPER ANNOYING that "rolling shutter" effect (the wavy lines when the camera moves) is driving me crazy. Looks like it was filmed on amateur cameras.
Ah, the final credit says "BohemiaMedia".... that mean "poor" right? So they did use amateur cameras. Hopefully they profited enough money from this nice production to afford pro-level cameras that won't make me seasick every time the camera pans or zooms!
Pretty amazing for 35’ of extension.
It's meters.
A little over 90 feet.
@@jamespayne8781 They said 35 meters? Makes more sense. It looked small due to the scale. Thanks
@@thereissomecoolstuff30 meters actually which is two additional trailers in length in 8 rows on 4 decks so it's quite a lot of exstra capacity. I have been 1st and 2nd Officer in DFDS (and 2nd Engineer) on these exact vessels.
@@jacobmygindpedersen1138 It is a lot. I enjoyed this but wanted to see more of the welding and wiring. That is back breaking work.
These details should have been worked out long before the ship showed up. Same way with shore power. If there are any delays due to the ship not being prepared then should be financially responsible for the delay
These details were worked out in advance, this is just TV drama at work.
No X raying of those welds? I can't believe that.
I (a marine engineer) cut a mostly complete superyacht in half and lengthened it because the owners wife complained the bathtub was too short!
Surely it would have been easier to shorten the wife
@@elelegidosf9707 ~ don't call her Shirley - her name's Audrey...
@@chezsnailez Ahhh, one of the lead jokes from the 1980 international smash hit movie Airplane rears its head once more. Nice to see it again; it's always a classic.
@@elelegidosf9707 ~ we'd often dreamed that Shirley Temple had gotten a role in that sprawling epic just to comeback that line with the addition of 'name's Audrey in this picture...'
Liar.
Adding just 30 m more simply don't worth it, but I guess the ships profile don't allow for bigger alterations.
Why not do a documentary on just how much just one ship pollutes compared to every vehicle in the world
the new section was made in just 6 weeks? It takes me 6 weeks to get to the toilet
They expanded their video very well 😂😂
If the most beautiful thing in the world to him is a metal ship....he's lost.
Big cut and shut, lets hope it doesn't invalidate there insurance.
Unlike this ship, cut-&-shut (C&S) cars are usually never done with this much attention to detail. A properly done C&S car will be just as strong as a new one. The reason C&S cars are the unroadworthy hazards they are, is because the work is done as cheaply as possible.
I would like to know what video camera was used to record all of this documentary. The reason being is that every time the camera panned, a distortion of vertical straight lines would be momentarily displayed. So it was a nice documentary recorded on a cheap consumer grade video camera.
the video are from 2007 and filmed on tape.
Ugh. Nobody noticed the wavy camera footage?
Why couldn't they make up their minds in the first place? I remember when they SHORTENED a container ship (the Galveston Bay). The wartime 'Frankenships' where more interesting though.
I wonder when we'll hear about this one breaking in half
Never. A stretched hull is just as strong as new construction.
How they've authorized something like that and with which safety assurance....??? 😥🤔
The cutter at 21 was not wearing safety glasses, unless his super speed was faster than a camera 🎥.
Well, you obviously did not see the other safety equipment covering his eyes... I mean cmon, eyes aren't that important anyway. But I certainly saw he had his company approved, OSHA certified "safety squints" on. 😅
safety contact lenses are the new thing these days!
He was wearing red welding goggles 🤦♂🤦♂🤦♂🤦♂🤦♂🤦♂
Im disapointed yous made a point of not covering the welding, cutting the thing apart etc... yeah you have to be careful - but is easy. Welding it back together is hard. As thick metal like that you can weld and no sooner you do - can get a crack in the weld straight away - as the metal so thick and strong as soon as it cools and contracts it can split like toilet paper - so I was keen to see how they did that. The rest of doco good / exellant but......
❤
German engineers show whats possible. I think only few ship yards are able for that and no one else so precise like German ship builders mechanics and engineers.
Lmao calm down your adulation! While it is a difficult job that requires lots of know how it certainly isn't a german prerogative. In fact, many other shipyards are able to perform that type of job on even more technically complex vessels like cruise ships
@@alex9621 I was going to post similar comment. 👍
Sorry to hurt your pride in German Shipyards but in the UK from 1970 to the nineties I worked on numerous Ship lengthening jobs. They were common place and not really hard to do. We cut a Ship in half horizontally and raised it by just over a metre, first time it had been done in the World. This was at Middle Docks Engineering at South Shields on the River Tyne, UK
Conversions like this is done all over the world - no worse and no better than in Germany.🤷🏼
But German engineering is definitely in general quality and high class!
That's a lot of work just to extend a ship 100 feet.
I want the chewing gum concession for this crew.
As long as I can have the sunflower seed concession.
Couldn't they just use a diamond rope to make the two parts?
Mega modifications
1:00:00 "By increasing the cargo space by 25%, the shipping company is saving one in four trips". Nope. It is saving one in _five_ trips, not four. Math is hard....
And 5/4 of people have trouble with fractions
The noise is way too loud
The amount of electrical line’s steam lines fuel lines are astronomical
tejus: A third world shit hole.
A little bit too much boring faces, but it is an interesting work indeed.
DFDS, De Forenede Dampskibs Selskaber/The United Steamship Companies.
It is interesting that the Germans and Danes communicate in English.
All that work then to catch fire and sink with all them Lamborghini, Ferrari, Range Rovers , Pagani , Mercedes Etc....
This was a good video.but WHY THE MOST ANNOYING HEAD BANGING MUSIC WHICH SPOILT IT
Let me show you my stretch lowrider ferry.
That is the most inept docking captain and crew I’ve ever seen. What a bunch of miss fits. What if the wind was blowing and there was a current.
Why not just have a fire ,collect insurance, then scrap it
The vessel is a money machine when it's in operation. DFDS is very profitable - a well managed company.
Stupid comment
@@jacobmygindpedersen1138 Ignore the ameritards.
I wouldn't want to sail in a re-constituted ship
Are you dumb or stupid?
I'm part Danish
I completely don't care.
Interesting video but voiceover is a stupid thing. Subtitles is much better.
What the DUCK I wanted to see the three pixels of ship come together and get welded. This 22 mm measurements then cut to finished and painted ready to float is bullship . It goes 49:00 minutes prepping for the welding yet you all show no welding. As far as I’m concerned this is a scam video. There was no ship build it’s all CGI pixels. I live next to a ship yard and there’s way more ppl working there then what’s in this not video. I hope my disappointment is clearly showing.
camara work was rubbish; filming their faces instead of the ship, rubbish.
Only German Engineers can carry out this type of complex work.
This work is not complex at all.
No. Conversions like this is done all over the world.🤷🏼 Currently the South Korean shipbuilding industry is king (even though China has overgrown it).
I was doing this in A & P Falmouth 30 years ago...P & O ferry : The Buffalo :
with crapp piiss poor welds. who ever made those weld should be canned. get welder(s) who know how weld.
The real mistake was ordering that ship from the begining. It was 6 years old. Delete on that time to built new extension, make plan for it, find the least expansive shipyard, a lot of talking in management, etc.... so how old was it when they found it wasn´t big enough ? It looks like management at first ordered a ship not large enough at the begining It would have been cheaper and less downtime. Somebody should be fired. The document was made in 2010. In 2024 it is 20 years old In 10 years it will be cut up as scrap metal.
I don't see why this can't be done in a shift or two... must be a government contract
What?? Are you high on something??? 🤣
@@jacobmygindpedersen1138 yes I am. Then and now. Why do you ask?
@billrowan1957 That explains I guess...😂 Do you know anything about ships? There are hundreds of cables, sensors and pipe systems that have to be rewired/connected/installed. It's not rocket science but it's a big project every time. That's why a conversion like this takes time no matter where in the world it is done. It's not like the ship yards are ineffective amateurs who don't know what they are doing - they are highly skilled experts. Why do you have the misconception that this can be done in a shift or three?
@@jacobmygindpedersen1138 it's called sarcasm. the use of irony to mock.
You sound like a UK government minister. With as much knowledge.
What is this 755 foot thing? Use rubbish measuring system throughout the video, or as done in the video, proper measuring system and only proper system, metrics.
".... 300 millimeters of paint ...." Really? REALLY? That's almost A FOOT of paint .... ! Is that a mistake, or is that really how much paint there's on the outer hull of these behemoths? Wouldn't it be easier to cover the ship in anechoic tiles, just like modern submarines? ya know, to make the ship "invisible" to sonar, thus creating a better stealthier ship in case it's gone under; or if a sub wants to ping and throw away its location so's it could get a better "fix" on the ship because visual is unavailable or something ..... ..... or if Sharknado becomes reality, and the soft steel needs to be protected by a thick layer of yucky rubber or paint or painted rubber.
Width not thickness. They remove paint left and right of the cut lines.
😱😱😱😱😱😱
Wow. So little detail of the process and too much drama and talking nonsense.
What ie so special about this? They've been doing it for 80 years
I don't miss television. The stupid ass theatrics, and self imposed time lines, the music.
