In 1969 I was in the Army and was on a Flying Tiger stretched DC-8 charter flight to Vietnam. Loaded to the max with GIs, there were no cabin dividers like all the regular airlines use for First Class, Business and Tourist sections. I was in an aisle seat in the very last row at the rear of the aircraft with a clear view all the way forward to the cockpit door. Without those dividers it was like looking down a long tube. Once airborne, I was surprised and shocked as to how much movement you could see at the far end, just like this ship!
You know the wings on aircrafts. They are flexable too. I remember first time abroad flying big aircraft for the first time. It was even Aeroflot. I had window seat. It was interesting to watch the wing moving up and down. Aeroflot didn't have the best reputation at the time, well, we were kids. We didn't know better. Some claimed that Soviet Aeroflot were safe but this flight went over Chernobyl the same week the nuclear accident happened which means at the end of the Soviet era. We know that The Soviet union broke down financially. But the flight went fine. It is just a digression on huge man made things that is designed to tolerate high pressure. it is all the same idea.
quite likely this is the very reason they close the curtains between sections after everyone's buckled in. last thing you need is passengers in the rear freaking out as they look up the isle and see the plane wobbling through the air like a javelin
You’d love Civil Engineering, and some of the things they need to do to make west coast buildings safe. During an earthquake, solid things are going to break; mailable things won’t. So try building a sturdy building with stuff that is meant to bend. I live in the Midwest, and we have the issue of buildings literally floating or sinking into the ground. Obviously over decades, but even things like the dirt around you moves and Mother Nature always wins. This is also why large concrete floor slabs are segments with grout in between them. The slabs can move independently, instead of fracturing causing cracks.
that's true, metal is elastic, but still... how much work hardening happens within that elastic deformation? how much does that work hardening bring the plastic deformation zone closer to the range of elastic movement the ship is subjected to... then you have welds, and all that is amplified along the length of the ship, sure, any single member, and joint is probably well within it's elastic deformation, and mechanical stress parameters, but amplified like that, it's still very impressive to the naked eye...
@@tylerufen There won't be any work-hardening if it's operating within the plastic elastic limit of steel. It would have to be designed against its low-cycle & high-cycle fatigue.
@@talk2thoran Euler buckling is a function of E, which is greatly reduced at flame temperatures. Of course, being a structural engineer you knew this already.
It is essential for the construction to be flexible thus it can sustain external forces. That not only applies to ships, but also cars, buses, air planes, road bridges, skyscrapers, rails, etc. This is the engineer's job to adjust flexibility according to expected work conditions. Cheers, 87
@@hyacinthbucket3803 well even rock when considered into a superstructure as a tectonic plate is fluid, especially seen during earthquakes. Everything is subject to fluid dynamics.
@@canismajoris6733 oh of course. It has to be like that to ensure good parts. I'm just saying engineering field in reality isn't as amazing for majority of positions as it would at first seem.
I'm not an engineer or anything like that, but I recently learned about how tall buildings require a certain amount of "give" for them to withstand heavy winds. The more I learn about the flexible but sturdy nature of large structures, the more appreciation I have for the thought, science and mathematics that go into making them, it's really impressive.
It's crazy that most large scale skyscrapers also need a huge counterweight at the top to add stability among other things! Some insane engineering. New York City is my favorite as I have no idea how that city is still building and still the way it is. That was all marsh land not too long ago. All that weight on top, not to mention the subways and underground, it's insanity to think it hasn't sunk too deep. I'm sure it's sunk a little, but you know what I mean. Flooding and canal sinking.
Rigid isn't ideal for large objects. It's like DUI crashes. The victim tends to get hurt or worse because they tense up. The driver sustains far fewer because he is looser. Same concept.
That looks like when you are in the last car of the subway train and observe the first one while in motion, zig zags all the way. Magnificent engineering.
I like subway trains. Amazing engineering, just like aircraft and ships. Sadly, my city doesn't have any subways (cough, cough, central USA). Also, I don't like crowds. Lol... But a nearly empty subway is fine. :)
@@thatguyalex2835 you should take them off peak hours, you'll enjoy those zig zags, dunno why, but there's some sorta magic to it, esp the bright lights of the cars when it's underground tunnel :)
Anon It would mean the metal would become brittle and crack easily, meaning higher maintenance costs and increase the potential for the boat to sink in high waves.
Hope someone at some point is collecting all this stuff. I remember walking around the ship at night on guard duty. When I got down to the lower decks I could feel a sine wave go forward and aft through the ship under my feet. We were in the Atlantic and I was so scared because of the forces on the ship. You are in the bottom deck of an almost 700 foot ship all alone in the middle of the Atlantic hearing noises you have never heard after living on the ship a couple of years. I'll never forget it.
Ive worked several years as a merchant mariner upon various ships. The reality is it can be stressful and very relaxing. It depends on you. Ive worked with those who can handle it and those who cant. One of my ships would routinely be in the bearing sea. -20degrees and 30+ft waves. And it SUCKED. Making your bed/rack into a taco so you don't get thrown out while sleeping. If your stateroom is against the hull near the water line it can sound like explosions every time a wave hits just right. Im a cook and you have to get real creative cooking for a crew in that kind of weather. If the ship is rolling like crazy that means the ovens, stoves, fryers, kettles are also rocking. But the other side of life is truly amazing. Comradery among your shipmates, being paid to travel the world. In the middle of the ocean there is no light pollution from cities etc, so you will get to see more stars than you could have even believed there to be. The color of the ocean over the Marianas trench will blow you mind. 2000+ miles away from the stresses of life. I wouldn't trade the experience for anything.
PlacentaJuan it must be really shitty to be so insecure by having such an unsatisfactory life making you feel the need to anonymously insult others on CZcams for a self esteem booster.
PlacentaJuan right, because vulgarity and insults prove superior intelligence every time. How idiotic of me not to realize this beforehand. We all have something to learn from the example you set.
It's a container ship. I have been to hundreds of these, I go to these areas when I perform maintenance on hull sensors like the speedlog and ecosounders. I love working in confined spaces. It's scary but fun at the same time.
@@harryflashman3141 anything that doesn't have give or flex would shear or snap on. All ships have engineered specs for how much "flex" is needed depending on the working load the ship is being designed for.
I was doing DD on a shipping company stock . Learned the average life of container ships is 25 - 30 year because of the bending shown in the video. The companies newest ship was 31 years old and just purchased a few ships that were 35 years old. This video puts that life span in perspective and good luck to anyone working for that shipping company
I was wondering what happens with all that constant fatigue building up in the steel. Also I don't know if ships have boilers or if theres much heat generated where the engines are, would there be anything transferring heat to the ship where it flexes like this? Most of the ships hull would be cold from ocean temps but theres any warm spots that cant be good either would it?
@@jamesharding3459 man i literally came here to say there are some pretty old ships working in the Military Sealift Command. Now i know of the ships you are talking about there are only 2 in seaworthy condition and they are both museum ships. There was one victory ship, another class from ww2, that served as an auxiliary right up to like 2004 before being retired and scrapped. So thats 60 years in active duty right there. I think the oldest vessel we have is from 1957. 67 years active duty service for the united states Navy. She carried rocket motors for the apollo program.
When I was onboard the USS Kitty Hawk we went through a typhoon of the coast of Japan. That ship would rear up out of the water at the top of the wave and when it hit the bottom of the wave it would almost stop us in our tracks the whole ship would shimmy like jello. All of a sudden that floating city felt like a tiny canoe! We lost life rafts and the racks they were attached to, as well as a huge rip under the starboard forward sponson. I think the rip was some ten to twelve feet long. I was so glad I was on that and not one of the support ships.
I have to ask, was that in 1979? I was on the cruiser Jouett (CG-29), one of Kitty Hawks escorts. It was October I think and we were pierside in Yokosuka as a typhoon approached. If we'd been on the other side of the pier, we'd have gone to sea with a lot of others. We rode it out with no damage. Went from there to Busan, S Korea where we learned about the embassy take over in Tehran. Returned to Subic to escort Kitty Hawk to the Arabian Sea until Nimitz relieved from the east coast.
1lIn 1951, dad was on a ship from Washington to Japan and then onward to the Korean War. He said they got into a storm where the propellers got into the air and shuddered the ship when they went back into the water.
When returning from a Med cruise on a troop ship, we went through the Strait of Gibraltar against 25-foot swells. When off duty, we would gather at the forward end of the galley, near the bow, where there would be games, movies, popcorn, etc. The bow was lurching so much, we decided we would see how high we could jump off the deck, if we timed it right. Back then I was in great shape, but not capable of jumping more than 18 inches. The bow would start up, I would jump at the peak; the bow would start down, and I would be five feet in the air. We Jarheads were never known for our brains.
So many people in the comment section are either old and experienced or learned enough to make lots of commentry on the structure of the boat and all, and then there's 16 year old me who's never even been on a large boat before..
Once a flight-engineer told me that the wings of an aerplane technically could be clapped together above or underneath the cabine. He might have boasted a bit, but I understood the idea and it helped me to lose my fear of flying. To see those movements in the ship, makes it more realistic! 💖👍💡
A few decades ago I served on a training voyage on a Navy LST. The well deck was in the middle of the hull and went literally from the bow to the stern, and you could look from one end to the other in it. In heavy seas that ship flexed, wiggled, hogged and sagged. Much more dramatically than this ship. Heavy seas were difficult for the sailors that got seasick.
The up-and-down bending, by the way, is called "hogging" when the ship is high amidships, and "sagging" when the ship is high at the ends. It's actually normal -- ships are designed to do this to dissipate the energy of the waves; more precisely, that flexing is going to happen no matter what and ships are designed to work with it. But it is wear and tear, and ship's engineers keep an informal but constant eye on the ship's flexing for increases in amplitude or any concentration of the flexure. If you're riding a mare, you know instantly when she's turned an ankle and started favoring one hoof; almost any driver will notice the change in feel of a tire going flat. Ship's engineers monitor the ship's flexure the same way. (Once you see that, it's right to start thinking about where your survival gear is. Don't ever let it be on the far side of that flex point from you.) With ships of particular lengths, the wavelength of the seas becomes very important; if the wavelength is too neat a ratio of the ship's length -- especially 1:1 -- then you get resonance and positive feedback that amplifies the bending and can break the ship apart. (This can be addressed by turning the ship at an angle to the seas to change the effective wavelength and break the resonance, at the cost of a more rugged ride.)
So how they can bend the metal like that? Coz I was in the other side thinking that is the same movement of a pencil when you move it up and down. Here is just a difference angle, but same movement. But what you just said is quite valuable. Is definitely worth to know where you need to be in case of, ideally. If the movement anyhow at the end can bend a ship is good to know where this will happen. Vital info. Thank you.
It's almost been 15 years since last I rode a ship. Wow the nostalgia. If I remember correctly these noises of the seas and the ships are less audible when you're inside the passenger rooms.
Ok, I know that this has nothing to do with anything, but I'm honestly surprised that there wasn't a Baghuul jumpscare at the end of this video. I probably would've shit my pants and screamed like a little girl.
Lewis Powers True! Titanic, however, went down for a very different reason... Even modern container ships would struggle with an iceberg, if hit the wrong way!
@@gooseknack Nobody hits icebergs anymore because there are: 1) Ice-patrol, 2) Radar and 3) Modern surveillance using night-vision, telescopic mirrors and modern optics. On top of that modern ships can turn much sharper than the Titanic, which had a tiny rudder for a ship her size and was outdated in designed even for 1912. Hitting other ships, monster waves or scraping underwater rock (by being slightly off position) is far more serious. Bad maintenance and old ships still sink ships all over the world. Usually those floating death traps are registered in Tuvalu or some obscure place where they're not so picky with what passes "inspection".
Quoting from the new international version of the bible, "so make yourself an ark of cypress wood; make rooms in it and coat it in pitch inside and out, and ffs dont forget to use titanium alloy rivets"
Event though it's specifically designed this way on purpose, it's scary to see the strength of the ocean and how it bends the strongest materials known to exist!
+AiNaKa there's 20 ft waves all the time in certain areas and at certain times. It's certainly not the norm for the Open Seas, especially not moving at 20 miles an hour, but it's by no means absurd.
the artist A cubic meter of water is one ton heavy. Let's just say that an average wave at sea is several thousands of cubic meters, ergo several thousands of tons. So yes, the ships need to be really sturdy to deal with waves.
Several years ago I was lucky enough to be on an 84,000 ton cruise ship that went around Cape Horn, Hornos Island, at the tip of South America. It was a rough passage with the wind gusting at 84 mph as we cleared the southernmost island. The intense, constant power of the sea, vibrating ship, howling wind, driving rain and spray were amazing. At no time on our passage did the sea calm. This was so different from the mountain storms I’d experienced skiing. There was no place to go for calm. No mountain lodge. No hole to burrow into. Lee side for shelter.
I used to be on the USS Michigan 727B. The A-Gangers had marked the ladder in machinery 2 on the bottom in accordance with certain depths and because of sea pressure, the ladder would move. We would mess with NUBs and tell them we could guess our depth because we were "attuned" and had our sea legs.
As ERUL/ERS on the 616 & 635 boats they used to send new guys back aft to get a bucket of steam, or a set of Fallopian tubes. We kept a contraption made of bent up gage tubing for just such occasions.🤣
Gatervision Videos Ha...my Aunt had a '79 Trans AM with T-Tops. Railroad tracks were scary. The whole car flexed to the point the T-Top panels visibly moved.
The Inuit kayak was made of seal hides, drift wood, and various bones. All parts were lashed together and wear partners lubricated with seal fat to form a boat that could handle heavy seas on a routine basis. Nothing was rigid and inflexible which made them amazing seagoing craft. Absorbing energy by transferring it throughout the craft. They were doing this before there even was an engineer on the planet. It just worked.
They WERE engineers; only difference is they didnt make money doing it. Humans have been building everything from massive, complex structures to small transportation made of light, flexible composites long before "science" came around to call them "impossible." And, no, aliens didnt help them.
@@Salamandra40k How can you be so sure they didn't get help? When you have great engineering feats happening independently across the world it begs the question of "Help from outside" theory. As for me, I am not sure but to discount alien interventions maybe premature.

@@randmayfield5695 ...No I'm pretty sure we know for certain that aliens did not, in fact, help native americans build boats. Nor did the vikings go to Alpha Centauri.

You tell me
It's a testament to the designers and builders that ships can withstand the forces placed on it from waves a rough sea. When large waves are at each end to a single large wave in the middle that bends the hull up and down as well as the waves twisting same the hull must be capible of absorbing. Seems like they'd just break in half. Bet some have.
Airplanes do the same thing; I was on a 747-200 in 1986 from and not long after departure from Mirabell in Montreal there was severe turbulence. The tour we were in had general seating in the large rear cabin and I was caught without a seat so I got in the jumper seat looking down the left isle and I could see the windows in the front cabin moving up and down as the enire lane was flexing. It's break if it didn't flex.
I’m an Aerospace Engineer and i can confirm that this is a fucking ship, a big wave hits the ship and now the ship is stil bending around the seven seas! That’s all
Agreed. I have no knowledge of marine engineering. Are they, as everyone suggests, designed like airplane wings to flex under stress? I would like a *real* answer to this question. Because without any doubt we know ships can snap in half when the bow or stern come out of the water, and only half the ship is supported beneath. So yeah. Wish somebody with conformed knowledge would come along and share some real expertise.
Cool. I spent a year on a 1000 foot LNG tanker with a passage like rhus that ran tbe whole length. During rough seas, you could see all floor decking bending up, then all ceiling bending down. Reminds me of that.
I've worked on cruise ships for over (20) years and they all twist and bend this way in rough seas. The worst danger on a ship is not breaking in half or even sinking, it's fire!
That's how they are designed. Lcdr, USN, retired. Many years ago I was on the tank deck of an old LST. While we were underway in heavy seas flexed the deck and the bulkheads.
Passeneger: excuse me, where is the restaurant? Crewman: just down the hallway and then turn left... no, right...no, left...i meant, right... damn storm!
charlie dee that's honestly my favorite thing to watch while flying on airliners lol, I think the new composite wings in the 787 flex like six and a half feet or something wild like that. As a mechanic its personally amazing to see the forces of flight acting on the airframe.
charlie dee Excellent point. I was in the US Air Force and they used to tell us that in flight, a B 52's wings flexed up and down 6 feet or more at the tips. I also learned that the wings were actually stronger when full of fuel as opposed to being empty. Pretty cool what strength and design engineers come up with.
Oldskool Funk...First, thank you for your service, I was also AF, 81-85. The U2's wings flexed so much they had little landing gear struts on the very end of the wings as not to strike the runway.. In everything flexibility is the key to longevity, whether dealing with a structure or people.
charlie dee Same to you Sir. I served from 84 - 92. I was an Aircraft Maintenance Officer and unfortunately got RIFed a year after Dessert Storm. Wish I could have hung in there and retired but those 8 1/2 years were some of the best times and I have no regrets. As a LT, in 1986 I was stationed at Shaw AFB, SC in an RF4C unit and we were TDY for 6 weeks in RAF Alconbury, England. The had Reccies also and a TR1 unit. The TR1 (or U2) ran a J79 engine just like the F4 and it was cool to watch them roll out for take off. As you mentioned, the wingtips would lift and take flight first, THEN a couple of seconds later, the main (centerline gear) and fuselage would unstick. This high tech glider would aggressively pitch up about 60 degrees, and it was out of there and through the ever present UK cloud deck in very short order. Landings we're fun to watch too because as the TR1 was slowing on landing roll out, a flight officer in a souped up El Camino "catch car" would chase it and get into position under a wingtip just in case the "pogo stick" wingtip gear failed. If you know military aircraft history, you probably will agree that those fellas at the Skunk Works definitely thought outside if the box when it came to aircraft design.
Oldskool Funk Kelly Johnson was way ahead of his time. Lots of records that SR 71 set before the turn of the century still stand. He designed aircraft nobody dreamed of in the days where a calculator was high tech.
I served in a frigate where if you watched along 2 deck all of the sections were twisting. Initially it was alarming but as a naval engineer it was pleasing to see the design working as planned.
I was an iron worker in college and remember sitting on the corner of a 20 story building looking straight down along the steel column all the way to the ground and seeing the building swaying as well as waves of motion going up and down the columns.
Yes you are correct. The Ships are indeed designed to have some flexibility to them. this is because do to the ship's being so massive they often reach crest to crest on a wave. The flexibility insures that the ship wont snap in half with a lower point under it. ( Father with around 20 years of sailing experience)

I sailed on a container ship that had two houses. The Bridge and Mates cabins were forward and the two saloons and the rest of the crew was in the aft house. The ship had low freeboard so any kind of seas would put water on the main deck. So us in the deck department when we had wheel watch, we used one of the two tunnels that ran fore and aft under the main deck. In heavy seas you could see the ship bend. Guys I knew who had sailed on the Great Lakes said that bending got so much it looked like the ship was going to break in two
This makes me miss being on the USS Carl Vinson CVN-70. That ship was so big that you could walk entire passageways like this and not see another sailor. You could go off and relax somewhere on the ship when not on duty and just chill. A quarter of the ship was off limits but most of it was able to be traversed.

Seen something similar on a cruise to Bermuda. We were following a hurricane down there so seas were pretty choppy. Best sleep I've ever had with those hurricane waves rocking me each night.
David Steer it’s designed to flex, otherwise it would break apart in heavy waves. The welds would break and the ship would literally come apart at the seams.

Stupid question but which side is experiencing more flexing? That is, are both sides flexing equally, or is this a feature limited to, say, the front of the ship to help with preventing the ship from snapping?
Mmm, 87, you must have been a bit bored and anxious during that voyage. Thanks for posting your scientific interests. Don't get in trouble from your boss, nor upset your shipmates ! . Bon Voyage ! o0o

Metal is elastic. When you understand this, the contemporary world makes so much sense. From machine screws to door springs to skyscrapers.

There won't be any work-hardening if it's operating within the plastic elastic limit of steel.

It is essential for the construction to be flexible thus it can sustain external forces. That not only applies to ships, but also cars, buses, air planes, road bridges, skyscrapers, rails, etc. This is the engineer's job to adjust flexibility according to expected work conditions.

True. It is the failure of the elastic limits of any material that you don't want, as that is " breakage". Even glass is elastic...up to a point
@@FlatlandMando That’s right, glass is considered an amorphous solid, somewhere between a solid and a liquid.

@@canismajoris6733 oh of course. It has to be like that to ensure good parts. I'm just saying engineering field in reality isn't as amazing for majority of positions as it would at first seem.
I'm not an engineer or anything like that, but I recently learned about how tall buildings require a certain amount of "give" for them to withstand heavy winds. The more I learn about the flexible but sturdy nature of large structures, the more appreciation I have for the thought, science and mathematics that go into making them, it's really impressive.
It's crazy that most large scale skyscrapers also need a huge counterweight at the top to add stability among other things! Some insane engineering. New York City is my favorite as I have no idea how that city is still building and still the way it is. That was all marsh land not too long ago. All that weight on top, not to mention the subways and underground, it's insanity to think it hasn't sunk too deep. I'm sure it's sunk a little, but you know what I mean. Flooding and canal sinking.
That say the water in the toilet bowls is always moving in super tall buildings like in NYC. Amazing and scary, but the engineering is incredible.

If it DIDN'T bend, that would be very poor engineering!!!
I don't think anyone is arguing against that.
Anon It would mean the metal would become brittle and crack easily, meaning higher maintenance costs and increase the potential for the boat to sink in high waves.
Anon well if it didn’t bend it would snap, Bridges do the same
karim lavji
That is a terrible analogy.
Daniel Girt well atleast it's easy to understand
Hope someone at some point is collecting all this stuff. I remember walking around the ship at night on guard duty. When I got down to the lower decks I could feel a sine wave go forward and aft through the ship under my feet. We were in the Atlantic and I was so scared because of the forces on the ship. You are in the bottom deck of an almost 700 foot ship all alone in the middle of the Atlantic hearing noises you have never heard after living on the ship a couple of years. I'll never forget it.
For those who don’t know, the metal bending is a good thing. Metal that bends is less likely to snap.
If they want it to bend they would make it out of rubber
@truthhurts3896 that is an ignorant comment. Metal is elastic. Engineers know this and design for it.

Always a white knight appears
Ive worked several years as a merchant mariner upon various ships. The reality is it can be stressful and very relaxing. It depends on you. Ive worked with those who can handle it and those who cant. One of my ships would routinely be in the bearing sea. -20degrees and 30+ft waves. And it SUCKED. Making your bed/rack into a taco so you don't get thrown out while sleeping. If your stateroom is against the hull near the water line it can sound like explosions every time a wave hits just right. Im a cook and you have to get real creative cooking for a crew in that kind of weather. If the ship is rolling like crazy that means the ovens, stoves, fryers, kettles are also rocking. But the other side of life is truly amazing. Comradery among your shipmates, being paid to travel the world. In the middle of the ocean there is no light pollution from cities etc, so you will get to see more stars than you could have even believed there to be. The color of the ocean over the Marianas trench will blow you mind. 2000+ miles away from the stresses of life. I wouldn't trade the experience for anything.

We all have something to learn from the example you set.
It's a container ship. I have been to hundreds of these, I go to these areas when I perform maintenance on hull sensors like the speedlog and ecosounders. I love working in confined spaces. It's scary but fun at the same time.
Is that flexing normal?
@@harryflashman3141 anything that doesn't have give or flex would shear or snap on. All ships have engineered specs for how much "flex" is needed depending on the working load the ship is being designed for.
That's interesting I had no idea that there would be so much movement. You would think it would lead to metal fatigue.
@@harryflashman3141 After many years, I would think so, too. I'm guessing inspections are required at regular intervals, just like in airplanes.

Man, not only is that cool to watch but the ambient noise is super atmospheric, it's messy and loud but atmospheric
I was doing DD on a shipping company stock . Learned the average life of container ships is 25 - 30 year because of the bending shown in the video. The companies newest ship was 31 years old and just purchased a few ships that were 35 years old. This video puts that life span in perspective and good luck to anyone working for that shipping company
Must be out somewhere by the black sea all those ships are past their prime
I was wondering what happens with all that constant fatigue building up in the steel. Also I don't know if ships have boilers or if theres much heat generated where the engines are, would there be anything transferring heat to the ship where it flexes like this? Most of the ships hull would be cold from ocean temps but theres any warm spots that cant be good either would it?
Probably why so many are lost at sea and never even reported on.
That lifespan varies wildly depending on how they were built and how hard they’ve been worked. There are a few Liberty Ships still kicking at 80.
@@jamesharding3459 man i literally came here to say there are some pretty old ships working in the Military Sealift Command.
Now i know of the ships you are talking about there are only 2 in seaworthy condition and they are both museum ships.
There was one victory ship, another class from ww2, that served as an auxiliary right up to like 2004 before being retired and scrapped. So thats 60 years in active duty right there.
I think the oldest vessel we have is from 1957. 67 years active duty service for the united states Navy. She carried rocket motors for the apollo program.
When I was onboard the USS Kitty Hawk we went through a typhoon of the coast of Japan. That ship would rear up out of the water at the top of the wave and when it hit the bottom of the wave it would almost stop us in our tracks the whole ship would shimmy like jello. All of a sudden that floating city felt like a tiny canoe! We lost life rafts and the racks they were attached to, as well as a huge rip under the starboard forward sponson. I think the rip was some ten to twelve feet long. I was so glad I was on that and not one of the support ships.
I have to ask, was that in 1979? I was on the cruiser Jouett (CG-29), one of Kitty Hawks escorts. It was October I think and we were pierside in Yokosuka as a typhoon approached. If we'd been on the other side of the pier, we'd have gone to sea with a lot of others. We rode it out with no damage.
Went from there to Busan, S Korea where we learned about the embassy take over in Tehran. Returned to Subic to escort Kitty Hawk to the Arabian Sea until Nimitz relieved from the east coast.
1lIn 1951, dad was on a ship from Washington to Japan and then onward to the Korean War. He said they got into a storm where the propellers got into the air and shuddered the ship when they went back into the water.
When returning from a Med cruise on a troop ship, we went through the Strait of Gibraltar against 25-foot swells. When off duty, we would gather at the forward end of the galley, near the bow, where there would be games, movies, popcorn, etc. The bow was lurching so much, we decided we would see how high we could jump off the deck, if we timed it right. Back then I was in great shape, but not capable of jumping more than 18 inches. The bow would start up, I would jump at the peak; the bow would start down, and I would be five feet in the air. We Jarheads were never known for our brains.
My old buddy used to serve on the USS kitty hawk. He said that the shitty hawk was one tough ship.

Where will this stop?
Mike Perth what about the fatigued welders fatigued welds??

The ship is bending! :3
🤣
truely amazing! Without this visual, its hard to understand the stress these amazing ships are under! thank you!
OH, that is fucking amazing. It reminds me of the way a jet airplane's aluminum wings flex and bend with turbulence -- a crucial adaptation!
Once a flight-engineer told me that the wings of an aerplane technically could be clapped together above or underneath the cabine. He might have boasted a bit, but I understood the idea and it helped me to lose my fear of flying.
To see those movements in the ship, makes it more realistic! 💖👍💡
A few decades ago I served on a training voyage on a Navy LST. The well deck was in the middle of the hull and went literally from the bow to the stern, and you could look from one end to the other in it. In heavy seas that ship flexed, wiggled, hogged and sagged. Much more dramatically than this ship. Heavy seas were difficult for the sailors that got seasick.
What does “hogged” mean?
@@ogadlogadl490 when the center of the ship is bent upwards (and the two ends of it are facing a lil downwards) - opposite of sagging
@@DeerJerky Ok got it! TY!
@@ogadlogadl490 no problem!
@@DeerJerky 👍🏼💋‼️
The up-and-down bending, by the way, is called "hogging" when the ship is high amidships, and "sagging" when the ship is high at the ends.
It's actually normal -- ships are designed to do this to dissipate the energy of the waves; more precisely, that flexing is going to happen no matter what and ships are designed to work with it. But it is wear and tear, and ship's engineers keep an informal but constant eye on the ship's flexing for increases in amplitude or any concentration of the flexure. If you're riding a mare, you know instantly when she's turned an ankle and started favoring one hoof; almost any driver will notice the change in feel of a tire going flat. Ship's engineers monitor the ship's flexure the same way.
(Once you see that, it's right to start thinking about where your survival gear is. Don't ever let it be on the far side of that flex point from you.)
With ships of particular lengths, the wavelength of the seas becomes very important; if the wavelength is too neat a ratio of the ship's length -- especially 1:1 -- then you get resonance and positive feedback that amplifies the bending and can break the ship apart. (This can be addressed by turning the ship at an angle to the seas to change the effective wavelength and break the resonance, at the cost of a more rugged ride.)
That's very well said!
As a horse rider in my youth, the riding analogy made perfect sense as I've experienced riding a horse with a healing hoof, thanks. 👍
Thanks for the info.
So how they can bend the metal like that? Coz I was in the other side thinking that is the same movement of a pencil when you move it up and down. Here is just a difference angle, but same movement. But what you just said is quite valuable. Is definitely worth to know where you need to be in case of, ideally. If the movement anyhow at the end can bend a ship is good to know where this will happen. Vital info. Thank you.
superb observation and so very well written, thank you for your explanation.
It's almost been 15 years since last I rode a ship. Wow the nostalgia.
If I remember correctly these noises of the seas and the ships are less audible when you're inside the passenger rooms.

Yeah, we don't want another Titanic
Lewis Powers True! Titanic, however, went down for a very different reason... Even modern container ships would struggle with an iceberg, if hit the wrong way!
@@gooseknack Nobody hits icebergs anymore because there are: 1) Ice-patrol, 2) Radar and 3) Modern surveillance using night-vision, telescopic mirrors and modern optics.
On top of that modern ships can turn much sharper than the Titanic, which had a tiny rudder for a ship her size and was outdated in designed even for 1912.
Hitting other ships, monster waves or scraping underwater rock (by being slightly off position) is far more serious. Bad maintenance and old ships still sink ships all over the world. Usually those floating death traps are registered in Tuvalu or some obscure place where they're not so picky with what passes "inspection".
I worked in a shipyard for 30 Years...this is why they use low carbon steel ..if they didn't flex they would snap like a twig
Noah’s ark was made of wood dude.

A cubic meter of water is one ton heavy. Let's just say that an average wave at sea is several thousands of cubic meters, ergo several thousands of tons. So yes, the ships need to be really sturdy to deal with waves.

Several years ago I was lucky enough to be on an 84,000 ton cruise ship that went around Cape Horn, Hornos Island, at the tip of South America. It was a rough passage with the wind gusting at 84 mph as we cleared the southernmost island. The intense, constant power of the sea, vibrating ship, howling wind, driving rain and spray were amazing. At no time on our passage did the sea calm. This was so different from the mountain storms I’d experienced skiing. There was no place to go for calm. No mountain lodge. No hole to burrow into. Lee side for shelter.

They were doing this before there even was an engineer on the planet. It just worked.

It's a testament to the designers and builders that ships can withstand the forces placed on it from waves a rough sea. When large waves are at each end to a single large wave in the middle that bends the hull up and down as well as the waves twisting same the hull must be capible of absorbing. Seems like they'd just break in half. Bet some have.
Airplanes do the same thing; I was on a 747-200 in 1986 from and not long after departure from Mirabell in Montreal there was severe turbulence. The tour we were in had general seating in the large rear cabin and I was caught without a seat so I got in the jumper seat looking down the left isle and I could see the windows in the front cabin moving up and down as the enire lane was flexing. It's break if it didn't flex.

Agreed. I have no knowledge of marine engineering. Are they, as everyone suggests, designed like airplane wings to flex under stress? I would like a *real* answer to this question. Because without any doubt we know ships can snap in half when the bow or stern come out of the water, and only half the ship is supported beneath. So yeah. Wish somebody with conformed knowledge would come along and share some real expertise.
I'm gay.
I know it's designed to sustain this just fine, but it's both tripy and creepy how much the ship can bend.
So quiet. So peaceful.
Cool. I spent a year on a 1000 foot LNG tanker with a passage like rhus that ran tbe whole length. During rough seas, you could see all floor decking bending up, then all ceiling bending down. Reminds me of that.
I've worked on cruise ships for over (20) years and they all twist and bend this way in rough seas. The worst danger on a ship is not breaking in half or even sinking, it's fire!
DARYL LOCKHART that is very ironic who would have thought that fire could kill you on the ocean but it can
Once all that metal catches fire, there is no saving it then
That's how they are designed. Lcdr, USN, retired. Many years ago I was on the tank deck of an old LST. While we were underway in heavy seas flexed the deck and the bulkheads.
I remember the first time I saw this video. I was very aware of the engineering involved, but it still freaked me out to see it! Very cool!

"If it bends it’s funny, if it breaks it’s not."
This felt like one of those eye exams where you have to look at the machine to see a barn or animal
It flexes by design, if it didn't it would break. If you knew how much an airliners wings flex while flying you would not step foot on one again.
charlie dee that's honestly my favorite thing to watch while flying on airliners lol, I think the new composite wings in the 787 flex like six and a half feet or something wild like that. As a mechanic its personally amazing to see the forces of flight acting on the airframe.
charlie dee Excellent point. I was in the US Air Force and they used to tell us that in flight, a B 52's wings flexed up and down 6 feet or more at the tips. I also learned that the wings were actually stronger when full of fuel as opposed to being empty. Pretty cool what strength and design engineers come up with.
Oldskool Funk...First, thank you for your service, I was also AF, 81-85. The U2's wings flexed so much they had little landing gear struts on the very end of the wings as not to strike the runway.. In everything flexibility is the key to longevity, whether dealing with a structure or people.
charlie dee Same to you Sir. I served from 84 - 92. I was an Aircraft Maintenance Officer and unfortunately got RIFed a year after Dessert Storm. Wish I could have hung in there and retired but those 8 1/2 years were some of the best times and I have no regrets.
As a LT, in 1986 I was stationed at Shaw AFB, SC in an RF4C unit and we were TDY for 6 weeks in RAF Alconbury, England. The had Reccies also and a TR1 unit. The TR1 (or U2) ran a J79 engine just like the F4 and it was cool to watch them roll out for take off. As you mentioned, the wingtips would lift and take flight first, THEN a couple of seconds later, the main (centerline gear) and fuselage would unstick. This high tech glider would aggressively pitch up about 60 degrees, and it was out of there and through the ever present UK cloud deck in very short order.
Landings we're fun to watch too because as the TR1 was slowing on landing roll out, a flight officer in a souped up El Camino "catch car" would chase it and get into position under a wingtip just in case the "pogo stick" wingtip gear failed.
If you know military aircraft history, you probably will agree that those fellas at the Skunk Works definitely thought outside if the box when it came to aircraft design.
Oldskool Funk Kelly Johnson was way ahead of his time. Lots of records that SR 71 set before the turn of the century still stand. He designed aircraft nobody dreamed of in the days where a calculator was high tech.
I remember witnessing this same effect when I was a passenger aboard on a large Alaskan-bound cruise liner in 2004.
Wow that's cool. I never thought about it, but it definitely makes sense that ships would flex like that.
Quite scary to see but less so when you remember that the ship was engineered with that flexibility in mind.
You act like ships are built from cold, hard steel!!
They’re made with LOVE!😍
Lol! 😲
More like wasting blood and sweat. It's a pain in the ass to work with.
Reminds me of the destroyer I was stationed on in the U.S. Navy. It flexed a lot going over those big Pacific swells.
That was a minute of my life I won't get back. I was waiting all that time for any bending to start
I served in a frigate where if you watched along 2 deck all of the sections were twisting. Initially it was alarming but as a naval engineer it was pleasing to see the design working as planned.

What's with these 10 years ago CZcams algorithm recommendation?
But yeah, this worth my time
Yes you are correct. The Ships are indeed designed to have some flexibility to them. this is because do to the ship's being so massive they often reach crest to crest on a wave. The flexibility insures that the ship wont snap in half with a lower point under it. ( Father with around 20 years of sailing experience)
This would be a great setting for a survival horror game.

Do you know about the game Monstrum? I don´t know if that is what you mean by a survival horror game on a container ship, but it comes very close.

As a mechanical engineer who doesn't know anything about how this boat was engineered, this shakes me to my very core.
It’s supposed to bend. If it didn’t the ship would snap due to the stress on the steel

1. *You* clicked and watched. 2. *You* admit to not even having the ability to look up things you like on your *own* but is lazy/spoiled/pampered/degenerate enough to follow the recommendations of a frickin' program. 3. *You* can't even take responsibility for that but scapegoats said program by whining here.
Generation algorithm whiner - the reason we should re-introduce eugenics.
Or are you one of those sheep lamenting how you lost precious time in your otherwise menial existence? What leads anybody to post something so utterly self-contradicting and useless?
I sailed on a container ship that had two houses. The Bridge and Mates cabins were forward and the two saloons and the rest of the crew was in the aft house. The ship had low freeboard so any kind of seas would put water on the main deck. So us in the deck department when we had wheel watch, we used one of the two tunnels that ran fore and aft under the main deck. In heavy seas you could see the ship bend. Guys I knew who had sailed on the Great Lakes said that bending got so much it looked like the ship was going to break in two
They say that this is what happened to the Edmund Fitzgerald.
This makes me miss being on the USS Carl Vinson CVN-70. That ship was so big that you could walk entire passageways like this and not see another sailor. You could go off and relax somewhere on the ship when not on duty and just chill. A quarter of the ship was off limits but most of it was able to be traversed.
My father used to recount how a sailor told him he would never stay on a ship that didn't flex.
That's so rad
Word...
Much respect for all the highly experienced 'Senior Welding Inspectors' (metallurgists) within the comments page 🤔😉😂
manos3790 self appointed experts you mean...
beatbasher YT is crammed packed with them 😢
Yeah, CZcams's got the foremost experts on every conceivable topic hanging out in the comments sections. It's incredible when you think about all the raw talent concentrated in one place. I suspect that governments, big businesses and research organizations throughout the world must spend all day scouring the CZcams comments to recruit new talent, rather than wasting their time with universities and wotnot. It's a head hunter's dream!
manos3790 enlighten the masses then.
nagualdesign Its bordering on an opinion fest for the ignoramus' within society. 🤔😉🤗😂
This is what a light mushroom trip looks like but imagine this in any hallway
10 years ago, wow! Well, thank you CZcams for finally recommending it to me.
Awesome! Thank you for including real audio! ;)
if i was on that ship i would bring loads of flex seal
That is too cool! Wish I would have thought about doing something like that when I was in the Navy!
Thank you for your service!
Seen something similar on a cruise to Bermuda. We were following a hurricane down there so seas were pretty choppy. Best sleep I've ever had with those hurricane waves rocking me each night.
Why the camera is not moving? It must be facing a lot of vibrations
SSC Sarathi maybe it is a self stabilizing camera
If the camera was moving, you would NOT be able to see the bending of the ship. It is securely mounted on this end so you can see it bend.
The only 2 words I can think of are metal and fatigue.
Peter Timowreef I agree..... and that probably why ships have an economical service life before scrapping, just like aircraft.
Given that this vessel is almost certainly made steel, I have two more words for you: endurance and limit.
Peter Timowreef 2 bad.
David Steer it’s designed to flex, otherwise it would break apart in heavy waves. The welds would break and the ship would literally come apart at the seams.
I was on a ship that flexed it was interesting. I use to call the ship. Shit. See what I did there
God, I just love how this comment section is 50 comments all repeating the same explanation about why this is necessary... I was worried I might have missed it...
It’s so bizzare,I can’t even imagine seeing it in person. Engineering is amazing man.
I wish I could flex like that!!!
+pkwentworth :)......try Yoga! I had a slipped disc, and a spine op, and had a spine like a plank of wood. But, tried a yoga class [beginners] and now my spine can flex again...I never thought it possible. My mum, aged 75, is flexible as a cat- you can regain flexibility. :)
who else here after watching that ship snapping in half video
Stupid question but which side is experiencing more flexing? That is, are both sides flexing equally, or is this a feature limited to, say, the front of the ship to help with preventing the ship from snapping?
Man, i get anxious just standing on a slightly wobbly stepstool, if i was on a ship like this I'd probably puke myself inside out
I presume a ship is designed with the metal flexing taken into consideration and also have some bearing on it's lifespan
Terrifying and beautiful at the same time
Like a coat hanger, a finite amount of bends until it breaks, kudos to the engineers who calculate the life expectancy of a ship.
ahhhh recommendations we meet again. See you in another 11 years. This is pretty cool though. Gives you full visual as to what’s happening
Mmm, 87, you must have been a bit bored and anxious during that voyage.
Thanks for posting your scientific interests.
Don't get in trouble from your boss, nor upset your shipmates !
.
Bon Voyage !

I thought they patch this glitch
