I had heard that they designed vessels to be flexible, so that they would bend, rather than break, but this is the first time to see it in action. So freaking weird.
Bridges, buildings, roller coaster and such. all flex. If they didnt. They would break or snap.
Same with wings on a aircraft.
So you guys are telling me most modern constructed items are made to flex’? How do make it so they can flex for example the concrete building, how can they make concrete flex, or does it naturally do so? Sorry, not the brightest star in the sky
@@brax300 It naturally bends, just if its built wrong it cant bend enough and it breaks.
Brax Farr if you ever drive over a bridge and feel like a flat speed hump, it’s an expansion joint. And walls where there is a gap filled with coloured silicone. It gives them the ability to move without cracking
Even though we know it's supposed to flex like that, it looks pretty unnerving.
In the fall of 1974 I was a deckhand on the Great Lakes on an ore boat built in 1908. We got caught in bad weather crossing Lake Superior downbound (fully loaded) and were contending with waves of 20+ feet. You could stand at one end and see the boat flexing up and down in the middle and twisting at the same time, with the steel screeching with every bend. Extremely unnerving.
I agree so unnerving especially that view from the engineers passageway! She was flexing a great deal in all directions, regardless the fact its supposed to do that I'd still be freaking a bit..

As an naval architect, you are pleased that such a phenomenon receives so much attention :)
Tirolekafi, I have been a mechanical engineer for 28 years. Designed a lot of different buildings in my time along with pipeline equipment. But a ship or airplane is a whole different animal. Would be fun learning the cross sectional loads that you guys design for in different ships. Keep up the good work. Bravo for Oklahoma, USA!!

Respect to you for building the world of tomorrow here and now
Wow - I always wondered how ships took these stresses, but I never saw it depicted this graphically. They must have to check for metal fatigue periodically, just like on an airliner. Great video!
while the interior shots looks scary you have to remember how long those vessels are. Sky scrapers flex in the wind in a similar manner.
Yes indeed in some cases the top floors can move as much as 5 feet.
The Empire State Building does not though.
Bridges too
@@NemeanLion- lol just lol
FuckYouWhosNext
They can be only 8 stories and you’ll see blinds sway in a mild wind storm. Actually, it’s the building swaying and the blinds hanging normally.
I joined the first big ship I was on , the Exxon North Slope in LA in Feb 1986. When I got up the next day after we were underway I looked out the port hole from my room which faced forward. The weather wasn't even bad just a blustery day really the deck was flexing sort of in waves.I remember thinking "I hope they know what they're doing".
Later when we were loading in Valdez, AK I was on watch out on deck. We had radios to communicate with the mate in the cargo control room . I was walking around the deck singing the one verse from SOMEWHERE OVER THE RAINBOW that I knew. As I walked aft in front of the control room the mate was pounding on the porthole . My radio was stuck in the transmit mode and they had been listening to me sing for about 10-15 min.I was mortified.Good days.Thanks for the video.
haha :D great!
ROTFL LOL

So it’s true. Most sailers are gay
@@johnsanders3492 lmfao
Like the wings on a commercial airliner. Amazing video, thank you very much for uploading.
Now just imagine if the passenger cabin flexed like that. Now that would be terrifying
@@TechNiVoltisgr3at seeing wings flex is terrifying enough for me.
@@TechNiVoltisgr3at Actually the passenger cabin does flex like that.....
@@alexanderfoelkel8316 I know. But not nearly as visibly as it is in this ship
1:40 - Wow, wasn't aware they flexed that much in that many directions.
I've seen other clips of ships flexing, but this one is one of the most impressive. Some great engineering and shipbuilding at work here.
I know it is doing exactly what it is supposed to do, but it does not make it any less unnerving!
I've never had a need to use the word "unnerving".
had no idea their was that much flex,wow
Torsion box runs the length of the ship, without it, it would break its back in five minutes.
Bas
www.marineinsight.com/naval-architecture/torsion-box-on-ships/
what it should be doing
It would be tremendous if you could film in a straight line from bow to stern.
And that’s why planes have curtains and short cabins
You can watch the wings flex on any jet you ride on. Same thing. The engineers just better know what they are doing.
Also why partially why planes have round and not square windows.
@@psychologicaltirefire8190 Because 90° angles induce cracks as a result of various pressurization cycles. Thus the angles are always rounded to avoid irreversible ruptures.
In weather like that, it makes you feel alive. I have stood at the helm and watched many a bow ploughing under the sea shaking up and down trying to break through the large waves to come back up. Being in the merchant navy was the happiest 28 years (1962-90) of my life...I still miss it.
That interior shot was scary to say the least.
SuperExcedrin add to that while you are walking there, the ship rolls 10 degrees side to side then the squeaks of metals grinding each other
@@meinfraulein380, the noise has to be crazy sounding & loud as heck
My Uncle worked freighters. In bad weather they lose containers easily. Once that happens the load distribution on the ship is normally lopsided at first and it makes it about 100 percent more difficult to control the ship. He was on ships that lost almost everything. Cars, 747 parts, whatever is in those containers goes into the ocean. It's actually safer for the ship to lose all its cargo. Loose cargo means containers smashing into ship on the deck. So many ways it can go wrong.
I’ve seen this on P&O Nedlloyd ships but never to this extent!!! Scary shit!!!
This is my favorite engineering video!
What more graphic example of designed and engineered in strength, flexibility and durability could one wish for than this marvellous, yet initially slightly unnerving video of a very large container vessel in rough seas?
That's an awful lot of stress to subject a hull to, year in, year out, yet every such hull has to be so rated in order to gain certification and be insurable.
This is so compelling to watch, and not something your average cruise ship passenger would want to see!
I have seen photographs of a cargo ship whose hull failed, splitting the ship lengthways in two, and those crew at the stern thought the approaching hull they could see was that of a rescue ship when it was actually the bow section of their own ship passing them. It was quite an eerie image to see in a book, I can't imagine how the crew felt!
As serving crew, I suppose it's best not to overthink about it too much, or go work ashore.
That's freaking amazing. My wife has an extreme dislike of sitting in traffic in a car on a bridge as trucks rumble by causing the bridge to flex and undulate.
Even though she bought and sold structural steel for 15 years and knows how strong and flexible it is, it's terrifying to her. I just think it's amazing.
Probably because it goes against our reptilian brain survival instinct. "If I stand on something solid, I won't fall. If I stand on something flexible, I will fall."
Might be normal flexing but I’d be waiting in the lifeboat till the storm passed.
Hans 😭😭😭😭😭
Save a seat for me, dude!
Nationof300 I know my luck, if I wait in a lifeboat, it’s gonna fall
Pussy
Hans, dunno... if a huge ship cannot survive in this weather, why would a tiny lifeboat be safer?
I don't know why but I love the videos of ships in the middle of rough sea. Also the videos of lighthouses with huge waves hitting them.
because it's man defying natures worst
Due to rolling, pitching and pounding; ships develop cracks
I'll take a ship ride any day, I just get in an airplane.
Aitor Tilla
Arrrr, ye have salt water in yer veins. Aye, that ye do, matey.
It makes me think of sex. All night long.
I remember the old Baltic wooden sailing ship I was on, in a storm would flex . Looking up at the deck beams from below I could see them bend a little . She was built in about 1909 and still going strong !
Great video. It makes me thinking back in 1977/1978 when i finished school and was waiting for my duty in the army. I worked via school at the office of Incotrans in Rotterdam and some colleagues (former Holland America Line crewmembers) advised me to go to sea for some time because sailing at sea gave at that time dispensation for the army-duty. I should sail on the lash carrier ms Bilderdijk from Incotrans and possible switch to the ms Munchen from Hapag Lloyd which were sisterships and sailing the same routes between North Europe and the USA. Shortly before going on board ms Bilderdijk the father of a friend offered me a job as freightforwarder for some time and i choose for this job and 14 months duty in the army. On Wikipedia you can read what happened with ms. Munchen end 1978 in a severe storm. This video remembers me what could happen with me when ............. It will allways be a big question to me but i'm still here and all the crewmembers of the ms. Munchen lost their lifes at sea.
I was on a cruise ship with waves bigger than that, didn't notice the flexing at all. It was one of Disney's, one of the bigger ones (139GT and 339m x 37m).
Very surreal see, especially with the mounted camera. Thanks for this!
That's because those disney boats are built with souls of small children
Thanks UA-cam for putting this BACK in my watch list after 3 years...........
Same here..... seen it before
It's really weird, was thinking the same thing
Very informative video. Shows again the extreme tolerances which must be designed into sea-going vessels and large airliners. Scary to watch, but quite normal. If as you say, the craft has been designed correctly. Thanks again for sharing.
Sonny Dean a
This video simply shows what happens to a flexible steel beam (a ship) when a fluctuating load (waves) are applied. The beam flexes like a spring. At leat 6 problems for the naval architect/structural engineer/ marine engineer to solve: 1. excessive loads leading to yielding and/or buckling of steel members, 2. extreme deflections leading to containers smashing together, 3. excessive accelerations of structure leading to uncomfortable living/working conditions for the crew. Add to this 4. roll, pitch and yaw accelerations/angles of the vessel due to the response of the ship to the waves, 5. local water pressure pulses on the steel plate grillages around the bow area (panting), 6. exposure of the prop in extreme pitching leading to over reving of the engines and potential engine shut down and you have a complex engineering problem to solve. Amazing that any of our Christmas presents from China ever arrive on time!
How about when 1/3 of the ship hangs free over a big wave, while the remaining of the ship has to support the 1/3 suspended weight.
Royale with cheese this is exactly what am I wondering sometimes watching this kind of videos: what force is working on the section connecting these two parts: hanging and supporting the rest of the ship. This is quite amazing, especially if you look at EMPTY ! cargo ship. Its structure seems so thin...
Lionel Playford or you could of just said...Yo that's dope!
You forgot to add in metal fatigue over time!
Lionel Playford iimmm
Great video, I work at a shipyard and can appreciate this
My truck trailer flexes like that to, the containers probably help with the rigidity and support.
I hope not. All the container ships that come to America go back to China empty
A single container mounted to a container frame provides rigidity. On a ship full of containers, they wouldn't add rigidity as they are individual units and move relative to each other.
There is a sort of diminishing returns effect because as you add more individual blocks and more weight infact the less ridgid the over all structure becomes, since the ' weight added ' serves no structual value past the first bottom row , i guess if you glued single rows of lego blocks to an inflated baloon its easier to think in those terms? The first layer would make it more ridged but the next and there after would un do that effect and slowly over come the base structure untill it became unstable. Iwatch youtube im an expert lolz

Those containers probably help with the weight and stress, you mean. Support? Come on...

This. Was. Incredible. Thank you for posting!
A rather good clip to show budding naval architects !
I know any large thing(sky-scraper, ship, airplane, bridge, etc.)flexes. Seeing it is cool. Thanx.
Except the Empire State Building.
NemeanLion fuck off with the Empire State Building, no one cares about that, of America.
This ship is doing exactly what it supposed to do. The ship is designed to flex. Without the flex the ship would break itself into pieces.
youandi06 yeah, we know - but it’s still impressive to watch
I was stating it because some people actually don't know its supposed to do that. You'd be surprised some people don't know
Might be design for it, but I'm sure the crew and designers would prefer a calm sea. Hard to make speed in that.
Thank you for shortening my list of things I didn't know, and adding to my list of amazing things I do know. Cheers mates.
I'm an engineer on a german shipyard, responsible for main cable routing in basic design. Since many year I have to discuss with some idiots here how important are expansion bends on cable ways. These guys have never been on a vessel in storm, only in their warm and quiet office. :-(
Now I have a very good help for my argumentation!;-) Thanks for sharing this video!
Weird flex, but ok.
The Captain of the ship I was on said the same thing and that is the ship needs to flex if it didn't it would buckle and split apart. We skirted two cyclones in the pacific and navigated the north sea flexing all the time. To the old salts it was normal but for the first timers it was scary as hell.
Thank you very much for the post! For years I was looking for something like that...
That’s absolutely amazing! I know a lot about land architecture, especially skyscraper architecture. I know that when you build a very tall building, it must be able to bend and sway with the wind, it does so to alleviate the stress on the higher stress points of the building. It’s kind of like a spring, but if they didn’t allow the buildings this way, and the winds were powerful enough, they could literally blow the building in half. Every single structure has a breaking point, I live here in Toronto, and while not an architect, I am a skyscraper enthusiast and amateur architect, haven taken many courses on skyscraper construction and industrial construction, I learned a lot about stress points and how they relate to the incredibly high winds we get here in the city. Look at the CN Tower, for so long and held the title of the worlds tallest freestanding structure, and to look at it you would never think in 1 million years that I could actually flex, but it does, and quite a bit too. When you walk up to it all you see is a massive concrete structure that you cannot see the top of, but in actuality in a very Highwinds the tower can sway up to 6 m in either direction. It takes a special type of concrete and rebar to maintain its shape while allowing flexibility to dissipate any stresses during heavy winds. If the building is not allowed the ability to dissipate that stress, overtime certain points of the building begin to weaken because of that stress building up, until you finally end up with a failure and a crack that could potentially lead to the buildings destruction. I’ve actually been in the CN Tower on a day the winds were gusting up to 120km/h, normally they close the tower during such high winds. Not because people would be in any danger, simply because many people would be absolutely terrified and get motion sickness, so to avoid that, they simply close the tower, but I had a friend at the time who worked in the tower, as one of the maintenance crew, and he let me in, because I always wanted to be in the tower on a really windy day to see what it feels like. He allowed me to go up to the sky pod, that’s the smaller pod above the main pod, you have to take a separate elevator to get to it, and even as we were going up in the elevator, the elevator cab was banging against the side of the shaft. Once you get up there, it’s not scary at all, unless you get seasick, because that’s exactly what it feels like, if you close your eyes it’s where are you were on a ship in the water in heavy waves. The only thing that disturbs me was the sound it makes, are you here is creaking and groaning and moaning the building makes as it sways 6 feet in either direction. It’s more psychological than anything else, because you’re convinced the building is going to break in half. I had to hang on to the railings along the wall to keep standing, but it was a fantastic experience, it’s a shame not many people get to experience it. Why am I saying all this? Because it’s the exact same situation with ships. During heavy swell conditions, especially if the ship is fully loaded, it must be able to flex and bend to alleviate the stress on the main structure. If it wasn’t able to, overtime the steel would literally start tearing itself apart, not something you want to happen in the Atlantic during a storm! I’ve never been on a ship at sea, but I’m assuming it feels exactly the same as being in a really high skyscraper during Highwinds, either way it’s a really fun experience, it’s not for the faint of heart, a lot of people have a major anxiety attack, throw up, or start panicking and sweating. Some even pass out, to which we of course laugh it because were just that mean! LOL! Thanks for posting this video!
Hearing the building groan beneath you would not be fun. Nothing to let you know if within expectations.
The quality of the steel is essential. The type used on these vessels you could bend in half before it would snap, not like the older, impure steel causal in many maritime disasters in the past .
Incredible footage dude.
You know it goes on but,
Damn its freaky to watch lol
Great upload. Thanks 👍
During WW2, there were ships of "Liberty" class. In order to produce them as quickly as possible, the body was welded and not riveted, as before. Unfortunately, many of them broke in two, at the beginning of the productions, because steel got harder, and stiffer having been welded, and that especially when exposed to low temperatures, in the ocean.
Simply an amazing video. And hats off to the designers who have allowed for vertical, horizontal, torsional, comprehensive and tensile stresses, keeping the combined stresses within the elastic limit of the steel.
Thanks for he video; i knew about this flexing og ships in high waves but seeing it as shown in the video is just amazing. Marvels of engineering indeed. Thanks for posting Claus.

Thanks for uploading this. I knew the bigger ships flexed, but seeing it like this was very educational.
There's so much flex there, it almost looks articulated. You'd think it'd spring a leak somewhere 🚢
Edmund Fitzgerald did just that. Broke in half.
Some type of flaw in the steel that the shipping yard which built it refused to admit....
@@brickpictureproductions3077 Really? I thought steel bends, not break. Buildings do this in the wind or in an earthquake.
@@hgjhgjhgification Steel bends until the breaking point. Even steel can not bend in an unlimited fashion. That is why the mixture of elements for any type of steel must be chosen carefully, as some bend better and some bend worse, some are more brittle, other are more flexible, each, again, with different structural characteristics. If the wrong type of steel is chosen or there was a fault during manufacturing, it will break or bend out of shape permanently.
@@Schnittertm1 looks like you know the nuts and bolts. Like wooden ships crack, steel ships flex, just wondering if you can hear it.
Very interesting. thanks for showing this
Just an amazing video. This is better and far more informative than any of the "above the waves" scary ships in storms videos I've seen.
Great video, real sound and no irritating music! Well done!
Don’t forget about the welders. They keep it glued together when the poop hits the deck.
That demands some serious welding skills to keep that togheter. Scary as f*ck to be on that vessel tho.
Tis why I respect Naval Architects so much, it,’s like building a metal house that has to float, and deal with earthquake, storm, tornado at the same time in a daily basis. Hats off.
Holy crap,, i have never seen the ocean nor have i ever seen a cargo ship up close,, now i got a small glimpse into reality and seen both on a almost or as close as you can get to personal with out being there and i have to say WOW, men and woman who work on these vessels deserve every penny they make and then some.
Of course it all makes sense but I'm still surprise about the extent of movement - great vid
Nice views and camera positions. Thanks for that idea.
That’s insane to see this kind of stress that really happens on a ship! Great idea of a video to share who ever shot this clip!
Rarely ever have I seen that's both terrifying and amazing at the same time.
Imagine a few cams like these on cruiseships, and then livefeed them to the cabins and restarants on big big screens ;)
Really nicely shot video, always nice seeing quality work, thanks!
(even if it's so creepy! lol)
Superb video which clearly marks the constraint of the ship at sea. This container carrier undergoes this
torsional effect. Which, without it, would break like a match.
It is not without reminding me of the course of storms off Durban in South Africa. Our ship, the Iraouaddy
was just 146 meters long. She was a bulk carrier of the Messageries Maritimes. The hollows there were over
50 feet. We weren't driving it wide with friends. And 17 years old, we were afraid.
I was a submariner for 8 yrs, but this made my hair stand on end. Great video, thanks a lot for uploading.
Stress makes strain.
Everything is a spring until it enters the plastic zone.
@Travis Bickle thanks man. I don't drink so feel free to offer it to the next attractive person you see.
When I was in the Navy I was assigned to an FFG, or fast frigate. I remember that occasionally when we were in sea's like this the screw would come out of the water and the blades would slap the water surface and send huge shockwaves throughout the ship.
+heffo and juff Have tried it several times, main engine sometimes would go on overspeed and shutdown....not funny in such weather
+heffo and juff
I used to work on oil tankers and often when we pitched the prop would leave the water, The housing used to rise smoothly then bounce downwards. Also the first time i saw the ship bend, from the bridge, i nearly crapped myself. I thought it was going to snap! I was young!!
+Mathew Reece I know what you mean! One time when I was on FFG-25 USS Copeland we were sailing in the sea of Japan in very rough sea's and I was walking towards the helo deck. The doors to the deck were open and we rolled so hard that I thought we were going over. l was scared to death that I thought we would roll over and capsize! Like you I nearly crapped my dungarees when I could see the horizon and the list we were taking. Some of the superstructure was damaged. I think the old FFG's were not really built very well. Cannon fodder.
I heard the same flapping on a tender. It took a lot more to bring our screw out of the water and ours was much bigger than a FF, but when it come out, a 500ft ship would shudder like it had hit something more solid.
My shop was on the O-3 level. When we rolled through some swells all we could see was water, then rolling back all we could see was sky. That's a tall ship to roll 30 degrees.
Liked how Lightfoot said it. "Does anyone know where the love of God goes when the waves turn minutes to hours?"
OMG YOU LEARN SOMETHING NEW EVERYDAY!!!! THANK YOU FOR THAT VIDEO!!!!!! I figured if it was stiff it would crack that open cause its important that that flexes.....I just didnt realize it was so much!!!!!!!!!!!! Thank you again 1000 thumbs up!!!!!!!!
Thank you. This is mind bending to observe.
Imagine being your time on ship and seeing the hallways flex like 2:30.
Bloody 'Ell, so much for 1/2 thou engineering tolerances/shaft alignment etc etc
Was an engineer on a trawler fir a nunber of years. The waves in this video are no bigger than I'd have in my bath tub. Real waves in the North eastern Athlantic are truly terrifying. Mountains of water.
Its one thing to be aware that structures and crafts flex and bend, its something else entirely to see it in action, like this. Fascinating and interesting. This effect is something a lot of games and their devs, etc, should take note of. Another layer of creepyness added to f.ex. horror genre's, on boats, long corridors and suchnots (of which there is a lot of) ^^
My father was a cargo ship electrical engineer for 22 years
At night he hid his key from his door in fear not to sleepwalk outside and fall overboard
But the cabin doors need key only for the outside. Inside the cabin, you can lock and unlock with a handle. Like the cars for example.
Yeah wouldn't make sense to lock yourself in a dark cabin and how do you hide something from yourself anyway ? In an emergency I would think it would be probably the stupidest thing a person could do.
@@MihalisNavara yes because it would be insane if everyone was locked in their cabin in the dark in an emergency with hidden keys all over . His father is either lying , insane or very very stupid 😉
I've seen entire horror franchises that were less scary!
Put this in a movie!
I would have expected some flexure but this is incredible. Amazing footage. Well done.
Witnessed this in person on two different ships while in the Navy. Very cool video!
Interesting video. The ship is designed to flex. Try to look at the wing of a B747 during take off, flying, turbulence and landing. You will see the tip moving a lot

Absolutely great video. Thanks.
I've head of sway factor, and even felt it's effects in the Empire State building, in NY. Seen it's effects on aircraft wings, too. Never seen it to this degree within a ship. This is excellent structural engineering reference video. Or at least, it should be. Those engineers really knew what they were doing, when they designed that ship. If she didn't bend like that, she'd break her keel, for sure. Thanks for sharing this.
Ships are flexible just like aircraft wings
Like others said. Done by design but so very freaky to see in video. I'm a pretty chill person but that'd get a NOPE from me.
Wow, that's nuts! Thanks for posting this!
I was aboard an US aircraft Carrier for 4 years and never saw anything like this. So amazing. It does make sense that the ship would need to flex. :) Thanks for the share!
My dad served on a Fletcher Class US Navy destroyer in WWII. They sailed through a Pacific typhoon in 1945. He said it was a bit un-nerving when he saw how the ship flexed when he looked through the compartments. Likely, very similar to this.
How cool to have served on a Fletcher in WWII!! It wasn't Johnston was it?
Yes what ship we must know!!
Im from Philippines and many Filipino are working as a cargo vessel crew coz the company pay them high salary.
Now I know why.
Wauw, I first saw this upload around 4 years ago, still amazing to watch, and still an awesome upload
incredible video of the stress and vibration of a vessel..well done
When you get off ship after a long long trip, it will take few days to get out that funny drunk state 😁
This is exactly the same when I sail with my Sevylor Caravelle over the Ammersee.
I’m amazed that the containers don’t fall off. Also how the drive shafts stay aliened.
Well, no matter what that is the most scary thing you can see there. It really needs a lots of gut to ignore it. It is just as in jetliner when she hits the storm and all of a sudden she is all over the place. You know that she has been designed to withstand that kind of punishment and yet it scares living daylight out of us. Great video and thanks for sharing it with us.

I guess the steel will flex this much for a very long time without work hardening, but in the end it will work harden. Perhaps that is when cracks happen and rust really gets going which seems to be the thing that retires most of the large vessels.
excellent comment
Yes and no. The steel flex never reaches the elastic limit so it doesn't work harden in the normal sense of work hardening. It does however fatigue over time, and that's when cracks set in. If it didn't flex it would be way overdesigned. Thank the engineers that work it all out.
Fatigue design life of ships = 20 years.
Hull checks for cracks = every 3 months.
The cost of updating electronics and fullfilling new regulations will be the major factors long before the hull has shown any damage, if it is taken care of properly.
You are welcome.
Similar principle to air-frame design, made to bend not snap. Watch out of your window at the tips of a 747 wings from stationary to take-off, they flex about 15-20 feet.
Fatigue, Stewart.
Thank you! So interesting to see how the ship as she moves through the sea.
Amazing video! It's something to see this vessel's backbone flex like that.
How often are those shipping containers lost during voyages?
Happens occasionally, not too often though.
I've always wanted to work on a container ship for some reason but not now . Great video
Come on don't be scared
+Sammy 750 I'm 73, and I would give my eye teeth to be working on a container ship, I can see the world, going from Asia to Europe via the ~Sues Canal, Then Gibraltar, to Southhampton, on to Germany and finally to the Americas. That would be the life.
