This sounds like a very fragile setup. It didn't take much of an error for things to go hideously wrong.
The craziest thing about saturation diving to me, is the fact that it takes less time to get back to safety from the *moon* than from 265 feet down. Decompression is so tedious and takes so dang long. After they pulled him out, he still had a week of hanging out in the chamber. :-O
You know it's really amazing to think about how short a distance 265 feet is horizontally, but if you make it vertical and put water between your start and end points it's suddenly heroic levels of complicated lol.
That’s if you believe a man ever made it to the moon. Highly highly unlikely imo
In modern sat diving they do deco on the ship, so it takes not long to go back to the surface
We've never been to the moon so we have no clue how to get back "to safety" in that scenario. Just saying.
@@zariballard lmao
On the note of Chris surviving so long without oxygen and the fact it was so cold down where he was: I'm an ICU nurse,we use Therapeutic hypothermia to slow everything in the body to prevent more damage and buy us time to fix whatever the problem is. After we correct the problem we gradually rewarm the patient. It's great to see when a patient wakes up like nothing has happened, just asking for another blanket! Lol, they don't usually believe us when we fill them in on everything that occurred and why they were so cold when they woke up.
Modern medicine is amazing!
My very first military EMS patient was an advanced hypothermia patient. Conventional wisdom at the time was, he'd have zero memory of when his body was locked rigid in a continuous shiver.
He remembered me, what I did, an argument with some senior NCO's that I won, a MacGuyverism to warm him during nonstandard emergency transport and more.
As I learned when he thanked me at a unit Christmas party some years later.
Kind of embarrassing, as I was just doing my job. But, good to see he was not only OK, but still serving and his family had grown.
Had only mild hypothermia once, had severe hypoxia a few times, once to tunnel vision and gray out before I recognized what was going on and mitigated it. Neither was pleasant, to put it mildly.
The last hypoxia event being due to a form of CHF, due to a thyroid crisis - during the first big peak of COVID.
Uttered by me to the ED doctor, "Oh, thank God it's only CHF! Wait, did I just utter those words?"
Doctor gave a great belly laugh, hard won, "Yeah, but I understand".
A few days later, I rebounded due to new treatment, despite one endocrinologist considering iodine to shut down my thyroid. Driving the poor nursing staff to distraction. I am, by nature, a rather energetic person, so idleness isn't really in my nature.
a body even when asleep cannot survive without oxygen for more than 3 minutes even when asleep stop wanting to find a scientific explanation there is none even he said it in the documentary I have no explanation for how I could survive the only explanation is god who decided otherwise
@@mero7446 We're talking about someone whose breathing and heartbeat have stopped therefore making the best of little oxygen he has in his system. You know shit about diving and basic human anatomy. Keep grazing...
@@mero7446Your god can only do miracles like save one life but is fine with civilization ending conflicts and endless human suffering. Your god sucks.
@@mero7446 You are very wrong. I, like the writer of the original comment here, am an ICU nurse, for about 18 years now, and I have seen MANY many cases of patients going much longer than 3 minutes without oxygen, whether in a code blue situation, respiratory distress, or like the O.P. stated, when in therapeutic hypothermia, and come out fine in the end. Although many do not, many do as well. I am a Christian as well and believe in God, but you are giving bad information here. I do not know where you got your "3 minute" information, but you are sadly mistaken. Please do not spew scientific misinformation. It hurts the medical community as a whole when people see things like this and do not know any better and believe it. Misinformation then spreads and leads to a dumbing down of society in general, as many people believe whatever they read on the internet.
I worked as a commercial diver for many years. This was a great analysis of this accident, heroic work from the dive crew and the ROV techs. Terrifying experience for all involved, but as with anything subsea, you need to keep a cool head if there is to be any chance of survival. ⚓️
Well put
@@waterlinestories this whole story was horrifying watching on Netflix and you did it justice. It’s all pretty incredible thank you for doing this it’s a miracle they both survived.
Absolutely crazy what happens it’s a miracle he’s alive and I Watch the documentary it keeps your heart pumping so fast not knowing what will happen
A cool head also slows your metabolism and protects your brain from hypoxia!
Have u ever seen anything strange down there?
I have a friend who did this for awhile. It’s wild the things they do. He had his line severed by a casino once. They were under this giant floating casino in black water. His line was crushed and a friend found him in the dark and dragged him up. saved his life. They didn’t even make a huge deal of it. Wild people.
Crazy
You know, some days you beat the house, but usually the house comes for the very air in your lungs. Weird way to gamble, God bless them
@@animula6908In places where gambling like that is illegal or the casino can evade taxes and laws they have a casino ship in International Waters.
When you work in a hazardous environment, it's just the norm to do whatever you have to do to pull someone out of the shit. After all, the next time, it just might be you.
Hence, it's not a big deal, it's literally business as usual. Although, if it was preventable, all manner of hell gets raised over the excessive risk imposed.
And well, I'd be moving heaven and earth to help out too. Might be an old army dude, but long ago I learned, although we are mostly water, water vs human, water normally wins, so help a brotha out.
And the most infamous and common last words heard on radio typically are, "aw shit" and I'm damned tired of hearing those final words.
Out in Louisiana it was or still is illegal to gamble on land. So they built 3 foot pools and put big casino ships in them
I worked with these guys on the Topaz with our dredge spreads for a few projects. Such an unfortunate set of circumstances but so glad Chris survived this ordeal. Huge respect to Duncan, Dave and John and all the others on the vessel for bringing him back.
Brilliant. Terrible circumstances but great outcome.
So seriously how much do you make for this crazy ish?
When their umbilicals were snagging, why could they not go into the template (the big box resting on the ocean floor)? Why did they have to go into the bell instead?
The template is an open structure. It doesn't hold any form of gas pocket.
@@waterlinestories Oh wow. So the tiny bell is the only place they could find refuge. Man they don't pay those divers enough.
As a former USN saturation diver, this was an outstanding explanation of this event. Well done!
Thanks I appreciate that.
What kind of jobs did you do?
@@BlyGuy Guess we'll never know😉
@@BlyGuy Gotta join the Navy 😶! Probably some of the coolest work in the Navy.
@@Chironex_Fleckeri no thanks on ever being a sat diver, living in a tiny chamber for a month to prepare for work. Naval aviator on the other hand, that I can wrap my mind around haha. Too bad I'm an ancient 38 years old
My dad was operated on (10 years ago) using a technique based on cases like this. It is so well documented now that has been used in operating rooms for 10+years.
The original case that spurred the research was a girl falling into a cold river in Scandinavia that survived a great time of being submerged in cold water.
What they did to my dad is that they lowered his body temperature by many degrees (8 or so I seem to recall) during the operation. It was an operation for an embolism of the lung.
Interesting.
So wonderful to see medicine move that far.
I believe this isn't that uncommon for some types of surgery, especially open chest surgeries. Some forms of heart surgeries do this too afaik.
@@nexaentertainment2764that’s correct.
My daughter had a heart surgery when she was a baby and her temperature was lowered as well.
And in EMS, the now current saying, based upon that entire practice and former ordeal, "Nobody is dead until they're warm and oxygenated".
Ironically, my very first military EMS patient was an advanced hypothermia patient. At a stage where consciousness is largely considered absent.
Dude remembered me and my efforts, some involving some MacGuyverisms. Shocked the shit out of me and well, embarrassed me, "Just doing my job, man". Got a medal for it too, never wore the fucking thing. Didn't wear medals awarded for just doing my damned duty.
Besides, in peacetime, it's doubleplus ungood to wear more medals than one's commander has. ;)
The documentary on Netflix is amazing because they show actual footage of everything and it's just crazy that this guy is still alive
What's it called
@@Nurse876 last breath
I'm just glad that the crew as a whole acted as quickly as they did, especially with the quick launch of the ROV, if not for that ROV feed I'm afraid they would've assumed recovery procedure, pulled the bell, then waited who knows how long for the DPS to be properly diagnosed and most likely swapped divers or given the previous bell crew plenty of rest before attempting a recovery... This was an amazing achievement, even without the incredible story of Chris surviving for so long. Regardless of what possible crew related problems may or may not have caused the initial positional loss (im not aware of the details), the immediate actions afterwards certainly proved their dedication to the divers... Great work as always, the editing, scientific info, and general education info in this episode along with the extra visuals was absolutely top notch! (I'm sure this one only took what? 5 or 10 minutes to edit? 🤣) Thanks for all the effort on this one (and all of your work)! 🤙
That's a good point, the ROV feed surely motivated them.
Funny we actually edited this one twice. I rather naively thought off effort it using original footage and then realised there is no way Netflix would let it slide and they'd get CZcams to take it down. So I contacted the production company and asked for permission which they said is unlikely but they'd ask. Anyway, I edited it again, taking out all footage from the actual accident. Pity but don't mess with Netflix
They weren't able to diagnose the DPS. As a last resort, they shut everything down, then powered everything up again, essentially rebooting the system. Thankfully it worked.
yeah i cant help but disagree tbh the guys down below handled it as expected but up tops repair of the dps system was kind of horrible a hard reset should have been one of the top 5 things done they stalled like 20-31 minutes before doing it if they did it sooner they could have saved everyone a nice bit of valuable time and the rov I believe may have been in the water already to help with the job I may be mistaken
I mean I don't know why it took 30 minutes to disconintue the DPS recovery, and didn't just attempt to take the boat closer sooner. Surely they knew that Chris' tether was cut, surely at that point that should have said, okay let's take manual control and take it back. Not 30 minutes. Also why was there no anchor. Surely they could have anchored the boat near the struture?
@@PBMS123 from what I remember from the movie 1 the storm was raging really bad 2 they didnt do a hard reboot until they were sure they had to as theyd drift with no motors, away from the diver. 3 Im not sure at what point it snapped vs pulling him. 4 honestly they probably thought there was zero chance he'd survive.
It would be pretty difficult in water to have an anchor in that current and depth of water with a boat constantly moving.
Excellent video. Been in the dive industry for 30 years - albeit recreational, still lots of harrowing experiences, but nothing like being untethered 260 ft down in freezing water… kudos to the crews and teams that rescued this chap.
Cool. My background is also recreational scuba. Thanks for watching
That crew was amazing. Everyone kept their cool.
You'd love the film "Last Breath".
Saturation diver loses connection with bell and umbilical, exhausts emergency tank and suit, still is recovered alive.
Having gone through a malfunction in breathing supply that induced both tunnel vision and full gray out before I recognized and was able to recover, yeah, it resonates.
Eventually, I do want to explore scuba.
Already have the first emergency lesson down pat, shit yourself afterwards, not now, you're busy trying to survive.
Oops, was thinking of a different video when commenting.
Amazing crew - obviously take their training seriously. Under stress little details usually suffer under the desire to save a life. To give those 2 recovery breaths right when they took Chris’s helmet off - that is the 1st step in a drowning rescue. So amazing that after such a huge recovery effort they still thought to take care of that small but so important detail.
He hadn't drown. He actually ran out of gas AND had lost his hot water.. Big difference and yes I do know what I'm talking about as I am working HSE Closed Bell Mixed Gas Diver (sat diver) since 1994 and who has worked on Topaz.
He had not drown. No water went in. But helped
@@sja9836 The helium had lowered his temperature already and then losing the hot water lowered just enough to help lower his O2 needs. It was just a perfect recovery all around.
@@bluewaters3100 well, at those depths, helium is both a frenemy and a friend.
But yeah, totally imperfect perfection, which is how one recovers from a nascent disaster.
Is it me or does this man have a hella relaxing voice as a presenter? man alive, totally soothing
Ha ha. Thanks
Survival after 40 minutes is still stunning, regardless of the gas or temp variations helping. Many decades as EMT/acute care/trauma centers and ERs without seeing CPR do much ever. The drownings were body recoveries each time ... except for a WARM (pool) water drowning of a 12 year old girl. Pupils blown; hour of futile resuscitation efforts ... dead by all science. Then just ... popped up, crying for mom. Zero effects even from the brutal resus; visited a week later and still fine. Impossible. Scared hell out of all staff. So extreme conditions can assist but sometimes it just has to be God. (Olathe Med Center ER, Kansas, circa 1987 or 1988).
Wow that is something. True though, science can't explain everything.
@@waterlinestories Freelance writer now. Amazingly my last book based on a haunted 1880s cabin I rented and hoo-boy, what an epic. (Usually history). Regret not noting names, etc but recall most.
Rare reply bounce; trying to be concise but you know the science. Girl was found by mom in backyard pool at bottom. Warm summer. So likely bets off in time it took there. She screamed; off-duty cop next door hops fence, pulls girl out and starts CPR.
We had a radio link; unit was highly trained paras. If you've witnessed any of this you know the scoop in minutes usually. Zero response to anything. Pupils blown so I was taught that was brainstem death; a switch; no margins or negotiations.
We're busy as hell in the ER but I have desk duty so listening in on an easy 45 minutes at scene AFTER say, 15 since call. Got to point of adrenaline syringe push into heart. Insane effort beyond normal as little girl.
Never saw one since but when rolling her in, a firefighter was perched on gurney assisting a HORRIBLE hydraulic auto CPR thing designed to continue after all people tire. Never forget that. Mom had stumbled in crying minutes before; I nearly had to carry her to the "quiet room" and pastor.
?10-20? minutes with us? Both trauma rooms occupied so ran it in curtain bay. Doc finally pushed curtain aside and tells me to get mom. Last hold of baby. At time all crap left in place thinking would show parent everything was tried.
Mom devastated as imagined; nearly carried between me and pastor. Will never forget the doc then yanking aside the curtain to see this girl SITTING UP. Sees mother, "Mamma! Mamma!". I was RIGHT THERE, standing INCHES from mom as I watched her eyes widen, rush to daughter. Then I notice each nurse looking like they were just robbed or something. Frowns and shock.
3 year as unit sec before EMT but CLEAR on witness. Wow, this biz for me if THAT'S possible. Recall to doc: "Yes! Way to go! You guys SAVED her!" only to have him turn white, glare almost angrily: "That had NOTHING to do with us."
Manifesto ends but thought you'd like the details.
Yes thanks I do.
What's great is to hear scientific people like a doctor acknowledge that sometimes it's beyond them.
On another note, freelance writer? I'm trying to find a way to work with a writer.
Don't suppose you wanna find my email address on the about page and hit me up for a conversation about writing?
I'm looking for someone who can be precise and not mince their words. Would certainly help to work with someone who can wrap their head around the details.
@@waterlinestories Gee, I dunno. I'm so busy snowbound now! Always open to new things. Stand by.
No supernatural/deity behind those cases who do survive, just science. It's well known that young people have a much higher chance of a positive outcome after extended resuscitation than old people, and it's also well known that drowning in cold and especially (near) freezing water has much better outcomes compared to the same happening in warm water because the body goes into a sort of hibernation which helps to conserve oxygen. I know of a case where a Norwegian woman had been submerged for AN ENTIRE HOUR, yet did not only survive after CPR but actually managed a full recovery. She tried to pass a frozen river but fell throug the ice and was swept under it by the current, hence why it took so long before others were able to pull her out of the water. The submergence into zero degree water is the reason she survived.
One possible explanation for how he survived so long is something called the Mammalian Dive Response. Essentially, when your face is submerged in cold water, it slows your heart rate considerably. This could be, in part, how he survived, along with his diving experience and being able to stay calm. He didn't waste any oxygen with unnecessary movements.
That isn't mammalian diving response. Nowhere even close...... Muppet
That’s literally one of the two potential contributing factors mentioned at the end of the video.
@@OneBiasedOpinion Yes, he did mention the diving experience, but I didn't hear anything about the Mammalian Dive Response mentioned, hence my comment.
It's not just cold water that this effect happens in. It happens in any water at all when your face and ears submerge into the water. Every mammal experiences this effect automatically so it would be no different than what happens in any other typical drowning - the effect wouldn't be strong enough to cause this. You can experience the effect yourself by just dipping underwater in a pool. Yeah it lowers your heart rate and breathing rate, but not really by that noticeable of an amount.
Not to mention the fact that he most likely wouldn't even have been under the effects of the dive response due to the fact that his face and ears were not all submerged into the water. They said there was water pooled in his helmet, but that wouldn't be covering his entire face and both ears - so no dive response.
The dive response is very strong in marine mammals like seals though and is a major contributing factor in their ability to dive to such extreme depths for such long periods of time on a single breath.
@@lgnlintyeah for sure …. Like it helps but by like 30-60 secs 😅 nothing like this duration …. It’s probably something to do with the tri mix
Still an incredible case of survival
What an extraordinary story, and how amazing that Chris survived. Chris would have used his remaining heliox and energy climbing the template, as remaining heliox ran out it becomes harder to breathe, and reacting to cold, all would have acted to increase the heart rate and oxygen demand. So how amazing when the body tissue (muscles etc) are craving oxygen, that bodily function could reduce so quickly. I have heard of children being resuscitated successfully from cold inundation, but this is the first time I hear about it being successful in adults.
Yes it is incredible. Thanks for sharing your thoughts
There's a saying in the medical world.. 'You cant pronounce a cold body'.
@@dana102083I heard a similar variant: "you're not dead until you're warm and dead."
There was a female doctor who survived after falling in a stream while skiing and 'dying'. Remarkable.
Heard this multiple times. My uncle was a Naval underwater welder …. This is amazing!!! Thank You for the facts, truth, knowledge & empathy!!!
Most channels are shock value! I reallyreally appreciate you ! ! !!’
Thanks for saying so I appreciate that.
I grew up in Greece. I remember watching dad fishing underwater and feeling proud of him. I started diving at 8 and fishing at 14. Summer meant diving with the other kids. Sounds funny but now at 58 I can say that in my life, the most important things I learned them from the dive. There is a feeling of eternal calm and silence that I cannot live without for long. For me, people who work in such depths are not motivated by money. They are philosophers and lovers of the greatest beauty of them all
Whatever they pay these guys is not enough incredible video of having the knowledge and perseverance to survive of one man and an entire crew working to safe his life.
Well put
Being an instructor and dive rescue team member I find this story fascinating and so glad he made it. Great job all involved. That took a team and Gods hand.
I've always been extremely intrigued by deep sea diving; from the history to the notable stories and the modern methods. Your scientific analysis of these often chilling tales, coupled with a knack for telling stories is what keeps me coming back for more.
I could see myself being a sat. diver in a different path in the game of life. So I really can't get enough of this type of content.
Cheers, mate!
Thanks. I feel the same way.
@@waterlinestories The pleasure is mine - and like many others, I'll be excited for your new video releases for years to come!
Brilliant. That really means so much to me. It's honestly great to hear. I've had another channel about how to scuba dive that I've been building for years and it barely had a fraction of the viewers that this channel has. It makes me appreciate your comments and support even more.
@@waterlinestories Well, anyone who would say starting a CZcams channel is easy - probably haven't taken the endeavor themselves!
I know the work that goes into editing, writing and the collection of information that you must tackle, to bring these videos to us - so I am stoked that this channel is taking off.
I am wondering if you ever plan on doing episode on the history of diving? Because, I think that would pull in a lot of the documentary-type viewers. That's not to say that there aren't already a few notable CZcams videos of that category; But I think your perspective on it would be very unique.
What got me into diving was watching a random recommendation about an accomplished cave diver. He was tasked with going deep into a famous sunken cave to retrieve a colleague and as you know: the outcome was not good.
So I was curious: What are your thoughts about deep cave divers? I think they're nuts! But I can see why they take the plunge, regardless.
Yes possibly, I've got an open tab called history but I haven't started filling out just yet.
This had me at the edge of my seat. I spent 2 years as a deckhand for a salvage dive crew and 1 year with a charter dive boat (Sand Dollar) in San Pedro CA. Assisted in 2 tri-mixes for a barrel sponge dive. This senario is waaay beyond me. I kept a cool head in bad situations but this crew... wow. What a team! Everyone went home 🤙💪👏
Lier you were NOT a deckhand.
@@faizanrana2998 lol, nice grammar. Thanks for trolling ✌️
@@thatLongBeachguy keep dreaming
@@faizanrana2998 you exist only where you type. No one remebers cowards.
I could never. I have so much respect for people who neither panic nor shut down and can captain ships, pilot planes, etc. My dad was like that. He was a medic and i guess ot suited his cold as ice demeanor. I on the other passed clean out in the children's hosp triage room when my daughter needed 50 stitches in her big toe. She had a one team of doctors and I had another 😂.
Your explanation and story telling of this event is truly incredible. Thank you for another fantastic, heartwarming,episode
My pleasure, thanks for saying so.
Your narration and outline of the event is top notch! Even having seen a glimpse of the comments at the beginning and so knowing that Chris survived, I was still watching the entire time tensed with bated breath in awe of how he managed to hang in there. You really capture a perfect balance of vital interesting technical/scientific detail as well as a respectful and captivating account of the human side. I've been subscribed since your first video but thought to comment for the algorithm. Your work has the quality I'd expect from a big budget docuseries. Thank you and looking forward to the next one!
Thanks I really appreciate that. The algorithm god's also appreciated that.
Thanks for sticking around. Hopefully I can improve as we go.
The fact he survived is the only reason I did watch. But I hear you.
@@waterlinestories it would be really nice if you were able to show really clear visual cues of the people you were talking about a few times while we got accustomed to a face and a name, thus making it much easier to follow the action with those references well engrained in our mind. It’s a very complicated story made more complicated by math and trying to visualize these people who aren’t well described. It becomes like an SAT math problem that is almost intentionally confusing. It’s kind of an odd way to tell a story but others really seem to like it. I hope I’m not being overly critical I think it’s very high quality other than the swirling story.
Thanks for that feedback. As soon as you say it, I can see that being done in a documentary euch makes perfect sense.
My background is teaching scuba diving and sailing so I'm trying to impart done of the technical info. What I need to learn is to unfold a story carefully.
I really appreciate the feedback and I'll take it on board.
@@waterlinestories well you’re absolutely doing something right because the algorithm is loving it! Please don’t get me wrong, I think it’s absolutely fascinating material and done in a very interesting way. A little more clarity in the story telling and I would not be surprised to see this channel absolutely explode with views.
3:20 "eats an apple while...."
that sir, is definitely a sandwich :P
Yes. There is original footage which Netflix owns the rights to. I've used other footage to demonstrate the story but in the original footage he is actually eating an apple. I tried to get permission to use the actual footage but you can imagine that request was declined. I smiled have rewritten my script.
Maybe when this channels bigger Netflix will take my requests more seriously. 🤣
I was a dive tec for a company in the UK at the time of this accident.
Iv seen the raw rov footage, the stomach churning feeling I felt when seeing the diver laying on his side and seeing the face plate on his 37ss starts to fill with water replacing the air.
The company I worked for was only allowed to go 50mtrs deep on normal air.
I'm so lucky I never had any accidents on my watch.
Unless you have worked in this industry.....you will never know the bond that the divers and support team have when at work.
I didn't know about this when I watched the Netflix documentary, and the makers did a great job of maintaining tension by not mentioning the fact Chris survived until he appears near the end. I don't mind saying that it brought a massive lump to my throat.
Also, shout out to all involved for showing such calm competence. Everyone working together, acting decisively when they knew what to do and improvising brilliantly when faced with something new.
Loved your summary of it. Now I'm away to binge the rest of your videos 🙂
Thanks
Great explanation! Not usually into watching such videos as I find some can get sort of boring very quickly but yours captivated me from the start and kept me there until the end. Thanks 😃 what a fantastic crew these guys were ! Keeping their composure and doing exactly what they knew needed to be done. It’s so easy to panic but they kept it together for Chris.
Thanks for the explanation on such a complex dive/rescue almost recovery dive.This type of diving is not for the faint hearted.Glad it all worked out for everyone.
Such a stressful situation.
For someone who doesn’t dive, this video was awesome! It explained it so well, I think I actually understand what happened and how miraculous the end result was! Kudos to the guys for remaining calm and not leaving a man behind.
I spent 10 years as a mixed gas and sat diver in the Gulf of Mexico. These guys know how to handle situation.
@@NancyRodriguez-bj3rx no I live in the states now
Your stories are so gripping, that it’s somewhat hard to hit the like button; but thankfully this was a happy ending.
Thank you, excellent work.
As someone who took college chemistry and physics courses as part of a bio degree and was quite mystified by concepts like partial pressure, you really broke it down to an understandable level.
Thanks. That's what I'm aiming for
On a psychological level the reason u understand it now Is because he explained it to u in a way that interested u
Always thought Dave was quite an odd bloke watching the documentary. When Chris was left down there he essentially said shit happens and that he wasn’t exactly his best mate. There was no empathy towards Chris’s situation, he reminded me of a synthetic on board a space ship you see on films. One other thing they didn’t get the ship back to Chris manually, they rebooted the computers to get the DPS working again.
Absolutely nail biting delivery. Thank you for sharing this with us - I had no idea saturation diving was a thing before today, and I certainly didn't know about this case.
Well then I'm glad I could give you a glimpse
Watch the film then - Even when you know the outcome it's nail-biting!
I just wanted to say you did an absolute stellar job on retelling the story. All of your technical portions were spot on and you didn't leave anything out!
Thanks I appreciate that
This is SUCH an awesome channel and I wish you had FAR more subscribers! I have spent literal hours pouring over saturation dive science, different explanations, etc. And through it all, I never could really understand it until now! thank you
Thanks. I'm an ex recreational dive instructor and I had scourger channel about how to scuba but for me the missing link was 'what does it all look like in practice'.
Telling stories had helped me to find a way to explain the concepts and I really enjoy telling the stories too.
Thanks for watching
An experienced commercial diver almost never dies due to his own mistake. It is virtually always someone else's. The person who made the bad decision that killed the diver is usually warm, dry, and perfectly safe when that bad decision is made.
It's refreshing to watch one of these videos where everybody lives.
What an amazing story. So happy everyone survived.
It's still a miracle he survived.
True
I don’t (can’t😑) dive & I LOVE watching this channel! Your story telling & script writing abilities are fantastic🙌🏼
I ALWAYS learn something new & enjoy sharing these videos🎉
Thank you for what you do & spreading knowledge💜
As a dive instructor, I helped get my grandson into commercial diving over 20 yrs ago. Wow, I can relate and it is soooooo amazing that he made it.
Glad he did. I would like to say that most of the worst, biggest accidents happened in the '70s and '80's but its still one of the most dangerous jobs to do. Everything has to go right all the time and thats almost impossible. Thanks for sharing.
@@waterlinestories Yes, my grandson will not do sat. Diving. Too dangerous and hazardous to health in general.
@@NancyRodriguez-bj3rx No. I’m now retired.
My best friend does this work and I cannot have more respect and pride for him. The folks do incredible feats.
This is what we do for patients that have suffered a sudden cardiac arrest, and I’ve taken care of many that we had to induce therapeutic hypothermia. It doesn’t always work, but when it does it’s a wonderful sight. American Heart Association recommends it for any witnessed arrest where time without high quality compressions is minimal
I know nothing about diving but was fascinated by this story, because you told it so well 👍🏻 Clear, concise and scientifically explained. Thank you!
Thanks 🤜🏻
Glad to see he survived. Nothing short of a miracle
The complex chemistry involved here on so many levels is just astounding. God bless the brave men involved in such tasks.
Amazing. Thank you for summing it up so precisely in the end.
Just wanted to say that you are a damn good story teller, and the stories themselves are gripping! As a new subscriber, I’ve been really enjoying marathoning through your videos.
ps. Im an exploration geologist and I listen to audiobooks while I’m in the field, and I believe you have a great voice for it. Would love to listen to you do a more detailed long form of these and other tales of the sea. Cheers!
Wow you and my father would have been kindred spirits. My father was a geologist and loved exploring the world that geological world taking us kids with him but he was very careful he didn't take us where it was unsafe in his opinion for us. He was very humble about his life and had been an engineer having learned his trade with the Army Corps during the Korean conflict. My father was integral in some of the great dam building of the Northwest but he hated what he saw as disregard to indigenous peoples and history. They also didn't like that development was being done in areas that were unsafe like Seattle Los Angeles etcetera but you can't stop that he said he just asked us kids not to go to places that and I was born in Seattle. My father could read plans but he couldn't read books however he taught university-level courses under the auspices of other professors as there was no one around that could teach what he could. I guess when you take a man's lifetime and he's one of the few left alive that can tell you about it it's worth a semester. I miss him..
@@valiantsfelinesmccarty6678 your father does sound like an interesting guy! I was very lucky and grateful to have had men like him as mentors. Even today in my 50’s, I work with men and women, some 20 years my senior, who were smart, capable, and tough as a coffin nail. They always have lessons to teach me and crazy stories to tell that I never get tired of listening to.
Yeah, I’m damn sure I would have really enjoyed time with your father. 😊
I’ve watched others cover this story but i love how detailed your videos are!
Thanks
Great explanation and great teamwork. It shows again: never give up.
As a former and present saturation couch potato, this video was very well made. Thank you.
Thanks, I appreciate you taking a deep saturation dive into this one. 😁
Absolutely amazing story.
Yes it's a good one. Thanks for watching
This randomly showed up in my feed. Fascinating story, thank you for sharing
You did fantastic explaining and telling this. Thank you!
Sounds like everyone paid attention during training. Outstanding job to all.
This is beyond amazing wow. Hoping he is okay.
Incredible survival story. Thanks for clear narration.
Great job as always! Appreciate your hard work on these. 🖤
Thanks. This was a particularly challenging one but a lot of fun and I think it came out pretty well. Always a nerve racking time pressing upload. Makes it worth while when I get comments like this. Thanks for watching.
Like many others on this channel, it’s an amazing, and frankly, almost unbelievable story. And very well told.
Thanks, yes it's a story that draws you in.
@@waterlinestories or drags you under! :-)
🤣 Kicking and screaming
Sredni? You must be knocking on a bit now, - not many centenarian polecats running about these days, even deified ones.
@@philhughes3882 I might be getting on a bit, but my teeth are still white. As for my thoughts, however...
Somehow the OceanGate sub accident got me here.
Well I hope it was a good discovery
Incredible! What a crazy world those guys live and work in. Respect.
Yep
Very well explained, you are clearly a very knowledgeable chap. Delighted all turned out well.
Although I’m not a diving enthusiast of any kind, this is the second time I’ve visited your channel to be rewarded with brilliant and compelling story telling. You really do this so well, and I’m actually a little shocked that your subscription count hasn’t skyrocketed.
I’m pretty discerning about whom I subscribe to these days but you earned that from me on the very first occasion. I wish you ongoing success.
Thanks, I take that as the highest compliment. Welcome aboard
@@waterlinestories Absolutely agree! Compelling, succinct, captivating. Looking forward to your continued success!
Thanks
Wow, your storytelling skills are so amazing I'm on the edge of my seat while you're still explaining the gas mixtures.
May any diver that loses their life on the job rest in peace, and may fate bless and keep safe any diver out there right now.
Thanks. Fate blessed Chris on this one
@@waterlinestories Absolutely. I imagine he felt like he awoke from the dead when he came back to from this
Yeah. I think it must have taken a moment to sink in.
Absolutely top drawer narration!! Watched the original footage from bibby several times and you have completely nailed it for the better!
Thanks, I really appreciate that
Great condensed explanation!
Sucha great story, and such a great explanation! :)
Thanks. It is a great story
You mentioned temperature and breathing gas, but you didn’t mention the fact that all his tissues were fully saturated, which I believe played a big part in his survival.
Yes, they use a slightly O2 richer mix in the bailout for this reason. Seeing as it only lasts a few breaths at that depth. The diver has no risk of O2 toxicity.
Thank you for making this! After watching the documentary I wanted something much more in depth to explain the details that the movie glossed over.
This is absolutely incredible . I hope these divers are paid a fortune . what an enormous amount of knowledge is required to enable this enterprise to be successful . If I knew anyone engaged in this work I wouldn’t want all this information to prevent completely fearing for their survival .Wow , what incredible thing’s go on in this world that we know nothing about.
Yeah it's pretty incredible. I think they get paid pretty well. I'm not sure it's enough for me to do the job but if still love to do a saturation dive.
It’s nuts that you can survive on helilum and oxygen
There must be long term damage
Possibly. I'd be interested to see the stats.
Terrifying story, as if it's from an underwater horror movie. Glad Chris survived.
Yep. Thanks for watching
Excellent explanation of the "law of partial pressures"... makes me somewhat relieved that I didn't sign up for Commercial Diving way back in my post-RN diving days.
Thanks. But commercial diving could have been like a ships diver depths rather than saturation diving at seriously deep levels.
None the less probably a wise decision
Such a clear explanation. Thank you for your work!
Thanks for watching!
Oh Christ. I cannot even think about how scary it must be to be in total darkness. I was doing training in a high dive pool once and the instructor told me to sit and wait as I had already completed the training being undertaken, somehow I drifted off. When I woke, I was full on panic mode, no idea where I was and that was in the light at 10m. These guys must have trouble wedging their massive balls up into those diving bells.
Those balls are where they store the extra oxygen.
I was alone on a beach in Hawaii. I decided to swim out into the ocean to watch the sun go down. When it went down it was suddenly pitch dark and my heart was pumping. Then I remembered that I had started a small fire on the beach and I looked around, spotted it and started swimming. For Chris to find that cage and start climbing in the dark was incredible to me.
I'm just an open circuit diver but we're all about taking the right gases for a dive.
A partial pressure of 1.00 means you're breathing the same number of molecules of a gas per breath as you would breathing that gas (on its own) on the surface.
So on the surface a partial pressure of 1.00 means that the gas is pure eg. 100% Oxygen.
Air is 21% so each breath on the surface has 0.21x the molecules of breathing pure oxygen (PPO2 = 0.21).
At 5x the pressure (40m) air has a PP02 of 5x 0.21 = 1.05 so each breath of air at 40m has 1.05x the molecules of oxygen as a breath of pure oxygen on the surface.
Too much oxygen is toxic - we spasm eventually and with a conventional regulator it usually falls out and we drown - and since it's not an inert gas like nitrogen, our body burns it which helps.
At depth we try to stay under a PPO2 of 1.4 - it's far from instantly fatal and a hyperbaric chamber gives you about 2.4, but with air breaks.
At 22m (3.2 bar) and shallower we're okay on 50% O2 (PPO2 1.6), and at 6m (1.6 bar) on 100% we take air breaks on long stops.
That's the deepest we can use pure O2 and it's the best gas for encouraging saturated Nitrogen to come out of our cells cos there's no nitrogen in it, hence getting to 6m fairly quickly and staying there.
Yep good summary
Wow, thanks for the clear breakdown of the incident. I can only imagine the amount of work and Experience(!) necessary to communicate this so effectively. I wish more people understood the risks these brave people take, all in a day's work.
Yeah it's s fascinating profession.
Thanks for your kind comment.
As you said, normally we fill the bailout with a .55 to .7 ppo2 which helps a lot in scenarios like this
Ah interesting, so the bailout has a slightly higher ppo2. Thanks for sharing
@@waterlinestories love the videos. I'm currently half way through my training hours as an assistant life support technician, so hearing all the stories that wrote our rules in blood is kind of humbling
Oh wow. I'll have to come pick your brain.
I did surface oriented diving back 35 years ago. We would fill the bailouts with a gas that would support life right to the surface, and I was told by colleagues who did sat that they did the same. Which means a minimum of 16%. That's only PPO2 of 1.44 at this depth which is completely fine for hours. We worked at up to 1.26 breathing air, and up to 1.6 breathing nitrox.
I don't know what the modern divers do, but PPO2 of 1.44 would make a huge difference to survival times.
@@waterlinestories yea haha i dont mind if you want to talk on discord or something
Very informative. Thank you.
This is up there with the craziest survival stories/rescues. Blows my mind, happy he made it.
It'd be interesting to hear how they discovered and experimented with different gas mixtures. Seems like a very dangerous thing to figure out
I'll have to look for specific stories. A lot of the discovery is made by navy who the bottom to share too much per perhaps I just haven't found the right sources yet.
They discovered oxygen toxicity during training for the Royal Navy mini sub raid on the Tirpitz during WW2.
One died and another seriously affected during training when they dropped below around 60+ft.
So they were pushing the envelope in many areas at the same time. Very successful attack also. It never sailed again due to Main engines being dismounted. Good books available written by survivors. True hero's.
I know they're testing use of the ketogenic diet with divers and US Marines for this.
Hey, what’s your backstory? You have a real passion for these videos which is obvious by the good production value. How did you get so interested in these specific topics?
Thanks for asking.
I started out after school as a recreational scuba instructor and then I got into sailing so I've spent a lot of time on and under the water.
I moved from South Africa to London in the UK and I wanted to stay connected to the water so I started a CZcams channel about How To Scuba Dive called Waterline Academy.
Over the last few years that grew really slowly and I kept trying to find the best way to explain the theory about Scuba Diving.
If you ever watch anything about making videos the mantra is that Story is everything.
So I started making these videos on that channel. It was one of many test videos I've made over the last five years.
The first six videos on this channel I originally posted there and they did NOT do well at all.
So I took them down and put them up on this channel and forgot about them.
After a few weeks I started getting a few notifications about comments on the videos and within 3 weeks of putting them up, this channel outperformed my original channel ten fold.
I love telling these stories because I love the topics and I find the theory behind the accidents fascinating.
I also see these stories told by other channels who don't seem to understand the science very well and so I guess it's something I try to concentrate on communicating as best I can.
Thanks for your interest, I really appreciate it.
Paul
@@waterlinestories Dumb question, what’s a “channel”? (As you wrote: “The first six videos on I originally posted there and they did NOT do well at all. So I took them down and put them up on this channel .“ )
I happened into this video when I searched “diving accidents”. A whole bunch of videos came up. After watching a few, I found one other of your video and I liked the way you present it. So I watched this one ahead of the other.
I’m afraid I won’t subscribe (not a diver myself, but have friends who dive). But I wouldn’t mind looking for your video the next time I’m in the mood for a few more.
@@aprilt7080 I mean on another CZcams Channel.
Ill also do some other stories on Ships, Yachts and other Maritime Mishaps.
Like this one for instance czcams.com/video/GmT0SAMwDVI/video.html
The reason they didnt do well on my other CZcams channel is because the topics were too different and people who want to learn how to Scuba Dive (Scuba Skills etc) arent necessarily interested in diving accidents like yourself for instance who might be intrigued about a situation that got out of hand but arent interested in learning how to scuba dive.
I would imagine CZcams will now suggest some of my other videos to you regardless of whether you are subscribed or not.
I hope that helps. Thanks for watching and asking.
Honestly, one of the most incredible stories i have heard of in a while. Bloody amazing.
Yep. That's why they made a documentary about it. Its such a good story. Thanks for watching
This channel has thoughtful scriptwriters and an excellent narrator - facts presented without contrived dramatic sensationalism that less professional post-accident/incident analysts interject into their reporting. Good job!
Thanks
There is one thing that The Last Breath did go over that you didn't, however, and I am not sure if it was fictionalised or not. They said that to bring the Topaz back over the dive site required rebooting *all* the main computers at once in order to bring back the DPS - something never done and never tried before, but they had to do it because manual just wasn't precise enough in the huge swells and wind on the surface. And it worked! The comps had suffered a cascade failure, which brought down the DPS, but once they rebooted, they had full control.
Was this what happened or did they find another way to reposition over the dive site long enough to collect their stricken comrade?
As far as I understand, they had to reboot completely and then they went full manual because it was the only system they knew worked and could trust.
@@waterlinestories Intresting. The documentary actually asserted the reverse: That they went manual, were unable to get anywhere near the site due to the extreme swell and cross currents, then rebooted everything to try and bring back the DPS - a calculated gamble that suceeded and the computers then brought the Topaz back to the template. Documentaries can over-dramatize things but this is actually the reverse: Can you imagine how dramatic it would have been if the bridge crew had to fight tooth and nail to keep the Topaz above the template long enough for Chris to be recovered?
I have to do some research to see which actually happened.
A reboot would have been essential, and all computers and back ups require rebooting at the same time.
This sounds like deep hypothermic circulatory arrest, a procedure that can stop safely stop the heart for up to one hour, now used mainly to perform brain surgery, but the Soviets used it for heart surgery starting in the 50's.
Interesting. Thanks for sharing
Isn't/wasn't it also used for heart transplants in some countries, cooling the body and especially the heart untill cardiac arrest sets in, after which the transplant was carried out? I can't remember if the procedure was done on the donor, the recipient, or both.
Yes I believe it was although I don't know the specifics.
Fantastic presentation thank you
Man these guys are absolute mad men. Nothing but respect for divers in general but especially those who do it will preforming construction jobs man…. Balls of god damn steel.
3:20 That looked more like a roast-beaf sammich than it looked like a Apple, js.. 🤷🏻♂️🤔😁
Yeah. Im not aloud to use the actual footage so I found something similar. I should have said something to eat rather than being so specific. Live and Learn.
@@waterlinestories It’s all good! Was just something that caught the eye. Was told well either way!. 💯
But you're right to point it out. I looked at it several times when editing and then was too lazy to go back and film again.
@@waterlinestories 🤷🏻♂️😁🤣🤣 Good enough reason for me to have not fixed it either. Too much effort for not very much payoffs! Lol
Netflix provided the viewers with less information about his survival in a much longer film. Not sure why sensationalism gets in the way of fact. Thanks Waterline Stories.
😂
I'm so glad to hear he made it.
as someone who was not a us marine saturation diver this was a great analysis
Such an underrated channel
Thanks
Amazing story, so pleased at the outcome.
Binging your content mate. Freaking brilliant presentation in everyone I’ve watched. I’ve heard all of these stories before but feel like I’m learning way more in your videos then any others. Again, liked shared and subed. God speed !
Thanks. Welcome aboard
Absolutely incredible!!
This is one of your better videos. well done!
Former commercial diver and SCUBA instructor here.
Excellent video explanation.
Well written, edited and to the point.
