@r m You're preaching to the choir. I didn't get any more time in the rack as enlisted and in much more austere conditions. I understand the path and responsibility of a CO but living conditions were an order of magnitude above the berthing spaces and conditions the enlisted ranks endured.
@warsurplus CO staterooms are not that big. Mattress is usually a standard twin, or full size. Not plush. And the COs all have to earn their way up to that spot- you don't get to be CO of a billion dollar warship unless you step up through the ranks and make it there. Not easy, most officers never get there, they get out of the service after 5ish years. Those guys deserve a bit of comfort for the 4 or 5 hours of sleep they might be able to get in a day.
I actually have a very very very big fear of indoor oceans like this. I went to a coast guard base in North Carolina in 2013 when I was in the Boy Scouts, and inside they had a wave pool, and a replica helicopter for practicing getting out of a submerged helicopter. Anyways, they turned on the pool and it started moving and I just had a secret panic attack and I was terrified. That was the day my fear was born. Watching this video is so freaking terrifying
As a long time professional in this field, this is without question one of the best if not the best videos I have ever seen. I know many others in our company are geeking on this right now. Great work!
This is so rad!!! I'm a music producer and all these same principles apply to sound waves except sound waves are invisible to the eye. It's easy to hear standing waves in a room. If you play a constant low bass frequency and move around the room you can hear how certain parts of the room have boosted bass while others have nulls. So cool to actually see these principles visually!
same here, i´m a prod/dj, one of the biggest jumps in my sound quality came from learning and understanding the sound as a block of air moving through the room, into your ears, reflecting and absorbing onto surfaces, and also the bandwidth of sound. A beginner often boosts the eq to make it pop out, but with time you learn to cut, and the more useless frequencies you cut, the cleaner your sound gets. Very few colleagues understand this principle. Also made my sound system in my studio 4 db louder just by placing it in the right corner xD. Might not sound much for the non musicians out there, but 4db is more than double as loud.
I always heard my friend who produces say the same thing that they are almost identical with a few exceptions. That’s so cool that sound waves and water waves are basically the same thing in different forms
Very educational and informative! Also the calculations that they have to perform is amazing. I could imagine it has to be accurate in order to determine the waves. Engineers are geniuses.
This is such a fascinating video. I am a mariner in the Gulf of Mexico and it's true; you can really feel the difference in the waves between a smaller area like the gulf and the wide open Atlantic Ocean.
I have lived near this facility since the early 70s and have always wanted to take a tour, but never had an opportunity.. I even knew someone who worked there in the late 70s, but never made it in there. This was the most amazing video I have seen about the facility.. Thank you for this... And let me know when you film a followup... I'll carry your bags just to come along for the ride!! :-)
So cool, love Miguel 's reaction to that model "much bigger than this would terrify me". His ability to scale the pool to the real world is so second nature, what a unique and amazing job.
As an Amature Radio Operator this really help me visualize different radio frequencies.. I really liked the part from 5:10 to 6:15 as it really helped me visualize the importance of SWR calibration an how it can affect radio equipment and amplitude across frequencies. Maybe I had to much to drink but I'm sure other operators would understand what I'm saying. Thought this was awesome because on paper you can understand the principle but in water you can see the "Magic".
We had a very big wave pool at SERE but it was not quite this big. It was just really interesting how rough they could make the water in such a small space without it feeling cramped in any way. We had to get dumped in with our gear and be able to get up and onto a life raft, and then be able to call over radios.
I really loved this video! I'm an oceanography graduate, and watching this excited me at another level. Thanks for all this wonderful content, Derek 🙌🤝💙
I worked a summer internship at carderock and I’m hyped to see a video on this awesome machine since we weren’t allowed to take pictures while we were there 😉
Great video and learning experience. As an intermedia surfer, this really helps me understand how waves are born. Thank you, and keep up the excellent work.

Went here on a field trip in middle school! They also mentioned that they’ve tested airplane wings with this system because air is a fluid that actually behaves much like water.
@Jonas H. Uh, yes it is. I think the term you’re actually looking for there is “liquid,” not “fluid”. But even so, the fact that air is a different phase of matter from water is irrelevant. Water and air are both fluids, so fluid dynamics apply to both ships and aircraft.
Fascinating video. Thank You for working with Miguel to explain 'rogue waves' so clearly. Others could learn from that. The sound analogy is also very interesting. Great work and beautifully presented.👍
Fantastic video. Started bodysurfing (thanks Dad!) when I was about ten. I still don't know what it is that I learned to feel and see to know when the "right" wave is approaching, and how I know where to position myself to enter it. Feels like an art. But, those guys probably have developed a simple three-step brochure.
Well those swell waves are a useful early warning that a storm is coming, I was thinking that early on in the video before you mentioned swell. The different oceans having different wave characteristics is interesting. It might give lost sailors a clue about where they are! It would have been good to have more explanation of buoyancy and how the mass or density of the ship's materials makes it float and have a certain percentage of it above or below the water level.
Gavin and Dan from The Slow Mo Guys went to one of these in Scotland but it's a smaller circular design. It was able to make a 90ft vertical wave and was VERY cool to see.

This is right near my house! I was driving past it to a hiking spot and saw this incredibly huge, long building surrounded by government fences and wondered what in the heck it was.
Oh hi, neighbour! I live right by it too! I drive past it whenever I head to Potomac village or downtown Bethesda; known for awhile it was a Navy research facility, though. (Were you headed to Great Falls when you drove by it, or somewhere else? Just curious.)
Hi, my first question after this video is why the water currents (natural convection that happens because of temperature gradients under water) are not taken into account in the formation of waves ? it would seem obvious that they are, but maybe their impact is far smaller than the wind ? If anyone has an answer... Thanks :)
I loved seeing the mathematical equation for slowing down the video replay speed of the recordings. That was awesome to make it look so much more realistic
Your videos never feel like they’re 20 minutes long! There’s always so much research into topics that we would’ve never known if not for your videos. Love the content.
@Jacob Shirley The videos he made in which I know he did this are: "infinite rooms", "The riddle" and his advertisement for self-driving cars. I'm sure there are others.
I love how the navy does all this research and development on the ships and about how different waters will affect them and then designs a ship for the arctic and runs them in the arabian gulf. (Nimitz class Aircraft carriers)

I have a question (i know it's not related to this video): I'm really curious about our moon and its relationship to our Earth's ocean tides. Does the moon loses its energy everytime it drags our ocean around the world?
I remember visiting here when I was in high school engineering class. We were testing some mini underwater devices with servos for an assignment. I was blown away by how large the pool was. Very cool to see this place featured in your video!
Very cool.... Haven't really thought this through much, but can water viscosity remain constant with the scaling and still achieve accurate results? If not, how is this corrected?
Salt water has a higher density so it is more buoyant, you can change the load weight and hull displacement to compensate for that and achieve a good simulation.
Kelly Slater's wave pool is actually much larger than this, it's 700 meters(2296 feet) long, and 150 meters(492 feet) wide. Though it's only 9 feet deep. So even taking into account the extra depth of this one Kelly's is still much much larger than this and is used for surfing.
I’ve seen computer simulations of waves and how they interact, but it’s SO awesome and WAY more impressive and intriguing to see it in the real physical world.
Great video and immensely instructive to a Captain. Now I will at least know the terms and what I am facing when near coastal situations. As to the Navy it would seem that the hulls are great it's the mechanicals there that are failing.
Ok so I'm a ham radio guy. I find it interesting that the low frequency waves dissipate quickly and the low frequency go long distances. This phenomenon is the same for radio waves, where VHF/UHF are line of sight and HF reflect and will travel around the world.
i love learning in your channel and what a sick animation 2d waves and points dragging amazing animator u have! i would love to know how it was done my mind is blow up
0:49 the largest freestanding dome in the world is tropical Island in germany with 360 x 210m (1181 x 688ft) and a height of 107m. It used to be a Zeppelin Hangar ✈️
This just proves how little we know about everything, unless we are formally explaned that or taught. Different oceans need different ships?? What!? I love how complex the world is. It’s fun.

This video bring to my memories of Wet N' Wild (It's no longer exist, tho') in Florida. We had a huge pool that generates wave, but I don't recalled it's from the wall... I believe it was from the below floor that generates wave? It was fun and feel much more safe than the beach's waves.
I know i definitely have a very detailed understanding of waves when they start hitting the bottom, lots of very specific knowledge that is not usually covered in science classes. Especially with how small environmental changes can drastically change the final outcome of the wave.
I would guess that surfers have a better understanding of when the wave base interacts with the bottom, and less understanding of the dynamics where this isn't going on. I was wondering at the beginning if they'd be able to control the depth, but they probably just plan to avoid areas where it matters when the weather is bad.
millions of dollars and hundreds of thousands of man hours into designing and creating this thing.... and you throw a rubber ducky in it... What an absolute legend.
technology these days is crazy! my dad was in the Navy a while back - so this is especially special for me too. cheers to everyone who trained in that pool!!
Action Park used to have an attraction called the Wave pool where hundreds of people would swim in something just like this, but several people drowned because the “Grave Pool” as they call it was the most dangerous attraction.
We had a very big wave pool at SERE but it was not quite this big. It was just really interesting how rough they could make the water in such a small space without it feeling cramped in any way. We had to get dumped in with our gear and be able to get up and onto a life raft, and then be able to call over radios. Needless to say trying to sit under a tarp on rough waters in a fake storm and also hear anything is difficult
You can get into the general details about SERE without giving too many actual details of specifics. Like I can tell you about some stuff about the M1 Abrams tank but I can't give you the exact schematics and the nuances to it that isn't public knowledge
Hi Derek :) At 14:00 Minutes, does the salination of the water may also have impact on/to the Waves? Thanks for all your beautiful work, time & love you spend!

During WW2 a typhoon hit the allied fleet in the pacific. The US ships had a pretty decent list of damages and lost many of the aircraft which were parked on the deck of their aircraft carriers. After having received the full list of damages a US admiral radioed the british for their damage report from the storm. The british, who build their ships for rougher conditions (north sea) simply answered with "what storm?"
Overseeing it's potential energy to prove it's place to begin a visual of creative choice it's something of a study and impressive to view, I like how there is a simulated blueprint which would trace back to it's diamond backgrounds.
I did five years in the Marine Corps and was deployed on a ship in 2019 for 7 months. We crossed the Atlantic from Virginia to Gibraltar and then across the Mediterranean down through the Suez Canal. Nothing like 7 months on a giant ship to give you an appreciation for the force of nature that the ocean truly is. Never seen waves that big in my life and probably never will again. Now I have an appreciation for the engineers who kept us afloat 🫡
I would think this wave pool could be helpful in training Coast Guard Swimmers to train for rescues but they said they don’t let people swim in it. I wonder why they don’t allow it for a multipurpose use?
Nowhere NEAR as amazing- but for anyone looking to try anything similar? Oregon's North Clackamas Wave Pool - not half bad if ever in the area and looking for some fun +wave simulated pool action Wishing everyone out there calm waters otherwise and a pleasant continuing day/night!

I don't know if anyone else noticed, but the naval ship (791) in most of the video is one of five Singapore built Endurance class LPDs. This one is HTMS Angthong (LPD-791) of the Thai navy, the other four are Singaporean.
This is fascinating stuff to a guy who spent 20 years sailing in the Navy from the North Atlantic to the Arabian Gulf. I actually had a shore tour with the David Taylor Research Center working with surface effect ships at their Patuxent River facility. Amongst the cool stuff we did there we did get to tour the Carderock facility and see the tow basin where they can pull model hulls over a one mile long pool that, IIRC, follows the curvature of the earth. Neat place doing useful research for us squids. Thanks for that.
The Navy still has paints that we call DTRC because they were formulated there. Now that the official name is NSWC Carderock, the tow tank is the David Taylor Model Basin. It really is a cool place to work.

Very cool video! Nice to see ocean engineering getting more representation. I've been to a couple different wave basin facilities similar to this one (testing wave energy converts) I think one topic that could have been discussed here is the Dispersion Relation, which mathematically identifies the changes in wave speed with frequency, although it is usually only used with linear wave theory. Another topic could have been the Stokes Drift, essentially the net particle transport moving with the waves, and the reason your rubber duck took so long to get to the breaking wave.
@Greg Dame yeah essentially it's the net horizontal velocity of a surface water particle due to wave action. According to linear wave theory, this net transport should be zero. The particle should make a full circular rotation. Stokes theory accounts for nonlinearities that allow this net horizontal motion. There is a wiki page on stokes drift if you care for more info!
i am just curious, what is meant by free standing dome? Because i think 'tropical island' is way bigger than that by 1181 x 689 feet and it's also free standing.
Genuinely outstanding content. I appreciate your channel greatly. It's so well produced, truly interesting topics, and conveyed in a non-brow beating way. It's one of the first channels I think of when I think about CHclip.
Fascinating stuff. Would have appreciated if you had touched on Navier-Stokes and why we still need to build testing facilities as opposed to full simulations. How far do you get with numerical simulations alone? How is it integrated with real-world testing? What's the percentage of simulations vs. testing in modern ship design?
is the wear and tear between a tiny model and a huge ship really compareable? especially the immense forces working on the ships when being hit by a huge wave or being carried at one wave peak in the middle or 2 peaks on the ends of the ship?
I am mainly impressed that all of the wave makers are so snug together that there is zero leaking behind them, despite all that water pressure, and yet they can still move.
The most interesting takeaway for me was, that different oceans require different strategies/ships.
Until now, my perception of boat ranged from small to big, but not in the dimension of place of operation.

This is so rad!!! I'm a music producer and all these same principles apply to sound waves except sound waves are invisible to the eye. It's easy to hear standing waves in a room. If you play a constant low bass frequency and move around the room you can hear how certain parts of the room have boosted bass while others have nulls. So cool to actually see these principles visually!
same here, i´m a prod/dj, one of the biggest jumps in my sound quality came from learning and understanding the sound as a block of air moving through the room, into your ears, reflecting and absorbing onto surfaces, and also the bandwidth of sound. A beginner often boosts the eq to make it pop out, but with time you learn to cut, and the more useless frequencies you cut, the cleaner your sound gets. Very few colleagues understand this principle. Also made my sound system in my studio 4 db louder just by placing it in the right corner xD.

You can get into the general details about SERE without giving too many actual details of specifics. Like I can tell you about some stuff about the M1 Abrams tank but I can't give you the exact schematics and the nuances to it that isn't public knowledge
@Jacob R I would have assumed so.
SERE? Are you allowed to all about that lol isn’t there a nondisclosure agreement
Hi Derek :) At 14:00 Minutes, does the salination of the water may also have impact on/to the Waves? Thanks for all your beautiful work, time & love you spend!
Thanks for all your love and support ❤️

i think this answer i'snt from Derek? fraud?? But anyway i dont use telegram..
I love his reaction with the concert analogy, you can tell he is going to use that in the future. 😄

You can see how much he loves his job and how proud he is of it. I love that he decided to wear a shirt with waves on it. So cute !!
This was absolutely fascinating
This is amazing. I wouldn't swim in it tho looks crazy
Thank you! I've been wondering for YEARS what went on in there!!!
❤️Hey, congrats you've been choosen randomly for our today's Giveaway kindly follow the instructions above to acknowledge your prize 📩🎊🎉
This is incredible. Best regards from Germany 🙂
During WW2 a typhoon hit the allied fleet in the pacific. The US ships had a pretty decent list of damages and lost many of the aircraft which were parked on the deck of their aircraft carriers. After having received the full list of damages a US admiral radioed the british for their damage report from the storm. The british, who build their ships for rougher conditions (north sea) simply answered with "what storm?"
Do they scale the water density aswell as the surface tension?
My dad used to be in the navy but I never knew the navy had that
4:45 I have always thought about the concept of superposition but on gravity waves. Is that achievable?
Overseeing it's potential energy to prove it's place to begin a visual of creative choice it's something of a study and impressive to view, I like how there is a simulated blueprint which would trace back to it's diamond backgrounds.
im really surprised they dont use this facility for Navy diver or SEAL training, or any other training where an oceanic environment is desired.
And what a dream job for engineers, fluid dynamics, and, honestly, any one who likes science that is fun, yet extraordinarily important

Anyone else up at 2am rn fascinated by the different frequencies the US military are able to artificially recreate waves at
Excellent! Now do one on Froude Number and biomechanics regarding the work of Robert McNeill Alexander who died in 2016.
I did five years in the Marine Corps and was deployed on a ship in 2019 for 7 months. We crossed the Atlantic from Virginia to Gibraltar and then across the Mediterranean down through the Suez Canal. Nothing like 7 months on a giant ship to give you an appreciation for the force of nature that the ocean truly is. Never seen waves that big in my life and probably never will again. Now I have an appreciation for the engineers who kept us afloat 🫡
I would think this wave pool could be helpful in training Coast Guard Swimmers to train for rescues but they said they don’t let people swim in it. I wonder why they don’t allow it for a multipurpose use?
Thanks for commenting/
The animations were amazing!
This was way more interesting than I thought it was going to be
Wow that’s wicked insane ❤
I used to have nightmares about multiple indoor pools in one building like this.
Nowhere NEAR as amazing- but for anyone looking to try anything similar? Oregon's North Clackamas Wave Pool - not half bad if ever in the area and looking for some fun +wave simulated pool action
Wishing everyone out there calm waters otherwise and a pleasant continuing day/night!
Thanks for all your love and support ❤️

I don't know if anyone else noticed, but the naval ship (791) in most of the video is one of five Singapore built Endurance class LPDs. This one is HTMS Angthong (LPD-791) of the Thai navy, the other four are Singaporean.
This is fascinating stuff to a guy who spent 20 years sailing in the Navy from the North Atlantic to the Arabian Gulf. I actually had a shore tour with the David Taylor Research Center working with surface effect ships at their Patuxent River facility. Amongst the cool stuff we did there we did get to tour the Carderock facility and see the tow basin where they can pull model hulls over a one mile long pool that, IIRC, follows the curvature of the earth. Neat place doing useful research for us squids. Thanks for that.
It's Persian Gulf not Arabian Gulf
@Ranter06 i suggest you look into the history of bahrain itself. not that borders or names matter. but apparently it matters too much to some.
The Navy still has paints that we call DTRC because they were formulated there. Now that the official name is NSWC Carderock, the tow tank is the David Taylor Model Basin. It really is a cool place to work.
@Ranter06 Just because some use the name doesn't make it right. Any ancient map will tell you what's right
@Eunoia Spent 3 years running minesweepers out of Bahrain. Locals called it the Arabian Gulf. So did the folks in Qatar.
I would pay *ANYTHING* to swim in there!
So simple, yet completely complex.

Yes but how do they eat up the waves on the other side so that the reflections don't mess up the waves?
studying the motion of fluid is a great way of understanding space time and quantum physics!

Very cool video! Nice to see ocean engineering getting more representation. I've been to a couple different wave basin facilities similar to this one (testing wave energy converts) I think one topic that could have been discussed here is the Dispersion Relation, which mathematically identifies the changes in wave speed with frequency, although it is usually only used with linear wave theory. Another topic could have been the Stokes Drift, essentially the net particle transport moving with the waves, and the reason your rubber duck took so long to get to the breaking wave.
@Greg Dame yeah essentially it's the net horizontal velocity of a surface water particle due to wave action. According to linear wave theory, this net transport should be zero. The particle should make a full circular rotation. Stokes theory accounts for nonlinearities that allow this net horizontal motion. There is a wiki page on stokes drift if you care for more info!
Can you briefly explain stokes drift?
Wow a very intelligent person, so many words I can't understand

"It doesn't look like a swimming pool"
I want to swim in it
i am just curious, what is meant by free standing dome? Because i think 'tropical island' is way bigger than that by 1181 x 689 feet and it's also free standing.
Facts weren't involved in this video.
For a guy like me that jetski's every weekend, this looks like heaven to me
Do they ever use fans to generate whitecaps? Growing up at Greenwood Lake NY, I always looked for whitecaps which meant good sailing on my Sunfish.
Genuinely outstanding content. I appreciate your channel greatly. It's so well produced, truly interesting topics, and conveyed in a non-brow beating way. It's one of the first channels I think of when I think about CHclip.
*Dont_Read_My_Names* .😑

Could this research help predict rogue waves and help mariners avoid areas with dangerous wave activity?
There is one at N.A.S. Pensacola. However, it's not used for testing ships but for training special forces and search and rescue.
Thanks for commenting/
How common are some of these wave shapes? The quilt pattern, the from-all-sides cone? beyond this, how do you keep a pool like this clean?
Smart conversation this amazing presentation a engineering a lot knowledge
Thank you for great sharing
Full watched here friend
Fascinating stuff. Would have appreciated if you had touched on Navier-Stokes and why we still need to build testing facilities as opposed to full simulations. How far do you get with numerical simulations alone? How is it integrated with real-world testing? What's the percentage of simulations vs. testing in modern ship design?
is the wear and tear between a tiny model and a huge ship really compareable?
especially the immense forces working on the ships when being hit by a huge wave or being carried at one wave peak in the middle or 2 peaks on the ends of the ship?
I'm sure they've analyzed that
This is amazing. I never imagined that a wave pool could be so big!
"Stop trying to make fetch happen. It's not going to happen!"
Also, those straight waves are super cursed 😂
Hebat sekali lab yang besar
Mungkin ini bukan lab.. tapi mini trial di alam
I am mainly impressed that all of the wave makers are so snug together that there is zero leaking behind them, despite all that water pressure, and yet they can still move.
@Jose Rodriguez yep there is a rubber seal in between them.
@Vigilant Cosmic Penguin At its best.
That alone must have taken some clever engineering.
@AhrimanIt's visible at 1:53.
@Jose Rodriguez This. It's clearly visible at 1:53.
It is truly very interesting and amazing
Hello
He basically summarized a whole college physics semester in one video 😂, why am I even pay for classes…🥲
