If you want to learn a bit more about deep diving and some of the incredible dangers involved, check out this video I made a little while back about a prominent cave diving accident: ruclips.net/video/kQljpMsyCaQ/видео.html
I spent 20 years as a commercial dive tender and hyperbaric chamber operator. This event is taught to every dive tender that has ever been trained since 1984.
You can die falling down the stairs, falling in your bath tub, accidentally setting your kitchen on fire, leaving your car running in your garage, etc. You can even die from just lying in bed too long..bed sores and pulmonary embolisms are nasty. Things can happen wherever. Just enjoy your life and stop worrying so much lol
I've read statements made by the tender that survived. He said he received NO assist from the company & was living at poverty level for 2 decades. The payout he received wasn't much considering the dangers & the horror of the accidents. I've worked night shift about 35 yrs. of my 41 yr. nursing career. 3a-4a is always Stupid Hour, which is when accidents happen & things go wrong.
@auntheidi9389 yup I was just talking to my fiance about how detrimental switching between days and nights for my 12s are. I've only been able to get about 4 hours of sleep in the last 48 hours since my last shift. It's not healthy. But the pay is good
As one would expect from corporate and political monkeys who rather sit on their banana piles than lift a finger to help their own mothers let alone grieving families of their workers.
@@wiretamer5710 Child abuse? You can't be serious. Most family names of European descent are bestowed upon a long forgotten ancestor and generally refers to their place in society, their physical location, or their occupation. Those designations then become adopted as surnames. Smith, for example, is an obvious reference to blacksmith. To have the last name "Coward," would imply that way back in his lineage, it's likely that an ancestor was just known for being cowardly or easily spooked. It's really not any deeper than that but you want to throw around "child abuse" for some reason.
The detail that has always stuck with me: part of Hellevik's SPINE was found on a ledge 50 feet away and 30 feet above the dive deck. That's how violent the explosive decompression was. The sole solace in this is that none of the divers felt a thing, this all happened in milliseconds. Physics is unforgiving.
8 atm is about 100 lbs/ sq inc. So 15000 pound per sq ft, so let’s say 30,000 pound of get out the door force. He’s 150 lbs, that 200 g accelerating force, so you’re dead without even hitting anything. After a blink, 100 ms, 1 g is 2 mph, so you’re doing 400 mph per blink, so if you hit anything, you’re mangled.
In forensics classes we studied the crime scene and horrendous doesn't come close to what happened. The three that weren't near the opening were turned completely inside out in less than a second.
My dad was an army diver in the 60s and 70s. He was an underwater mine sweeper. The stories he told, of accidents and people panicking during training.. Honestly, he gave me a fear of diving. He did not inspire me to follow in his footsteps.
Yeah, one of my mother's brothers was a professional diver who died of a horrific accident while working that my mother never told me the details about. But it was so traumatizing for her that even just the thought of me going scuba diving made her hyperventilate.
Yeah you've certainly got to be made of stearn stuff. Bet your dad had balls of steel. Whatever they earn they deserve it, not many people could do it, so I have tons of respect for them.
The only comfort anyone can take from such a horrific and shocking incident is that their deaths were instantaneous. Such a dreadful way to go, and so traumatic for the crew and those people charged with the grim task of retrieving their remains and cleaning up the disturbingly gory scene. The poor survivor though.
It's ridiculous that potential hazards were identified, regulations changed to prevent it from happening, and then exemptions were given to the very places it was designed for! It's disgraceful that it took so long for the families to receive compensation. The only 'bright' side is that the deaths were quick, they likely didn't have time to realise what was happening.
@@john1701q Obviously, one could argue some of the blame. But there's also the dangerous working conditions that make "idiot-proofing" necessary. That includes the newly required clamping mechanism that this particular rig was somehow exempted from having, as well as other features that could have also reduced the likelihood of accident (as pointed out here, pressure gauges and warning lights). If businesses can cut corners, they will, whatever the cost... that is, until someone gets killed or seriously injured, and they get slapped with an expensive lawsuit, which ends up costing them more than cutting corners anyway. If you expect people to do dangerous work, then it behooves you to spend accordingly. But since too many businesses end up skimping on safety, "nanny gubmint" regulations are necessary to make sure said businesses do everything possible to ensure safety, both to employees and consumers.
@jrneal1220 there's only so much you can be spoon fed in life, that was a critical part of the job and that person wasn't paying attention. It's that simple
@@23Butanedione They were being made to work until 3 am, in extreme conditions. They were all working overtime, exhausted, in a stressful, isolating location. The equipment for communication was sub-par. The idea that people are infallible, and that if a mistake is made when being put in such intense situations that it's on them is asinine. Especially since there had been developments that made such errors impossible to make. Individualistically, yes, the man who removed the clip was responsible. But the idea that that's as far as investigations go is genuinely just childish thinking. We should want things to improve. And when we have things that make that happen literally infront of us (I.E. significantly better equipment and processes), choosing to ignore them and shrug is a dereliction of responsibilities.
@@23Butanedionethere's several reasons listed in the video as to why the inner door wasn't closed in time, and why the outer one was assumed fine and opened, all in quite comparable ways people have occasional brain farts at any other job, or people get complacent about how things need to be done and what can be skipped etc because they've been doing the job years and haven't had a problem doing it a certain quicker way, *so far*. It's established here (and in other videos that have covered it, Well There's Your Problem goes into a lot more gory detail) that the company not bothering with/not being interested in putting money into safety features to match the potential risks meant it was inevitable, it just needed more than one small mistake to happen at once. People "not paying attention" happens several times a day for a second or two at a time when you're on autopilot from habit, or having just done a 12+ hour shift as they had, etc. It's fair to suggest the consequences for that don't mean you and your workmates are instantly killed.
Yes, the absolutely instantaneous rapid decompression and the damage done is a marvel of the power of the forces of physics and how fragile the human body is.
Thank you for giving so much detail. Before this I'd only heard versions that eliminated the extremely limited communication between the divers and the tenders made even worse by terrible weather and cacophonic noise. Those versions with such limited information left the impression that the tenders were reckless fools. Now I know they were very tired men doing a hard and hazardous job with insufficient communication and safetly equipment and under extreme environmental conditions. You do a great service to all the victims of this horrific accident, the tenders included.
I don't think I'd heard those details before either. I'm pretty sure other videos I'd seen on it did say it was likely a mistake from miscommunication, but they didn't really go into the conditions that would have contributed.
Yeah, lots of channels are more worried on describing in gruesome detail what happened to their bodies than give a proper context to the tragedy. RIP unfortunate divers.
It's always surreal to really think about how tiny mistakes can have such instantaneously catastrophic consequences. When you do a job, you are constantly aware of the simple things that are huge mistakes in context, but you never really think about how little and easy those the actual action of those mistakes are.
Yep, I've worked on the trains for 30yrs. When I was a young apprentice, I remember not putting the signal casing on correctly (basically rushing). Thankfully my supervisor noticed it, I got the biggest bollocking ever, it was probably the best thing to happen to me, since then I double check everything. It's often small mistakes that can have disastrous consequences.
Yeah, I find it weird to think about too. I feel like, psychologically speaking, it's kinda the same as forgetting to turn off the TV before you leave the house, a simple momentary slip, but the context has vastly different consequences.
@@artfulscruffif you are working an important job and you are going "la deda deda" not paying attention to critical components for the job and treating them the same as "forgetting to turn off the tv" then you are a liability
@@23Butanedione I think you misunderstand the point being made. It's the idea that it's something as small as that can lead to huge, disastrous consequences. If you leave your TV on, all you get is a slightly bigger energy bill. But in these extreme working conditions, something small LIKE that could lead to deadly results, depending on what it is you fail to do. Certain jobs require extreme levels of vigilance, and things that would look meaningless to laymen and outsiders, could be the difference between life and death to specialists.
Something that often gets left out is the fact that both the divers and tenders were at the tail end of a VERY long shift - they were fatigued and all wanted to get the process of transfer over with quickly. Add the noise, no good indicator system and no failsafe, this kind of tragedy was inevitable. The force of 9 atmospheres spontaneously decompressing is comparable to a shot from a 19th century artillery cannon. The diving bell didn't just fall away - it became a giant cannonball, and the tender that removed the clamp was right in the path of it. The three things they needed and completely lacked were interlocking failsafes, indicators, and checklists. They didn't even have a decent checklist to run through, and as the aviation industry can tell you, checklists are vital to operate complex equipment whose controls must be used in sequence. Even a checklist that told them to double-check the status of the inner hatch before unclamping might have prevented the accident. It never was the tender's fault, though he got most of the blame. The ultimate blame lay with the Dolphin company, for operating a rig out of code with no safety failsafes and pushing their diving crews for illegally long shifts. The divers, at least, passed away instantaneously, though the details of what happened to Hellevik are best left to the imagination. If you want a deeper look (no pun intended) into the world of saturation diving and its dangers, the excellent documentary "Last Breath" goes heavily into it, including a situation nearly as perilous as this one.
Fascinating Horror's concise and informative style of explaining these tragedies lends itself well to being shown in the workplace for safety lessons. It should be.
And they should be shown to shareholders and leadership to remind them that cutting costs and ignoring safety regs will result in them being featured on this channel.
Based on other stories on this very channel, that almost seems fast. There's so many where they're obviously owed something and they're either still fighting decades later, or they just got nothing.
@@hellomark1 That is usually in cases with hundreds of victims and a payout of either hundreds of millions, or even billions, it's actually very rare for a handful of families to have to wait a quarter of a century for closure.
And what’s even worse is that the “guy who got sucked out” got sucked through the door leading to the diving bell. Which is already bad enough but the door was NEARLY closed. There was only a sliver open. Just the mental image of a fully grown human being instantly sucked through a gap the size of a dinner plate
Pressure is a scary thing. You're better off in a decompressing spacecraft than a decompressing diving chamber. If a steamship has a steam leak the way to find it is by waving a broom handle around until it gets sliced off, by all accounts as effortlessly as a lightsaber through butter. These are the sort of workplace safety videos we need.
One of those avoidable disasters where best things you can say about it, outside of the sole survivor, is that everyone at least died instantly and that it's an excellent bad example.
This is by far the best description I've seen of this accident. Most pay short shrift to the technical details and focus instead on the shockingly gruesome nature of Hellevik's injuries.
This is by far the best explanation I have ever heard of this incident. I've researched this before, but I don't feel like any other source has adequately explained nitrogen saturation or decompression sickness and you explained the results of explosive decompression so much better than I've ever heard before, and I've had to learn this for work. Excellent video!
Thank you for NOT including any pictures of the poor diver who was forced through the open door. There are images out there but they are extremely graphic and gruesome. This incident revealed a strong need for a better system of handling diving bells like this. It’s absolutely ridiculous that it took over two DECADES for the families to be compensated by the government for such negligence.
Whilst in some senses it seems bad that such images are out there, graphic images of workplace accidents are sadly the only way to get the message through to some people. However, such images on the internet should always be behind a warning.
Thanks FH for tactfully and respectfully describing the physical devastation of those men. The reality was far more extreme and gruesome than you let on! Awful story but it taught some important lessons!
I love the respectful, unsensationalized way you present these stories. Tragic as they may be, I find it fascinating to examine precisely what happened in these situations, what the outcomes and lessons learned were, and appreciate the concise, factual analysis your documentaries provide without the use of unnecessary shock value or graphic imagery. Excellent work as always, FH.
Does not matter how many times you hear this story, it's still one of the most gruesome accidents ever and it never gets less impressive to hear the details and dangerous of sudden decompression. At least the guys were gone fast and instantly without suffering.
I’ve never looked favorably upon the use of robots to replace people in the workplace. In this instance, however, I see the wisdom of doing so. This was a terribly tragic accident.
Robots being used to do dangerous jobs is definitely one of the exemptions I give. Robots making my food at McDonald's? No. Robots performing bomb disposal? Yes.
The moment when Hellevik's body was ejected reminded me of a story of the most shocking event my dad seen in his 4 yrs of USAF service as an equipment mechanic (layman's terms, he fixed the machinery that helped fix the jets), There was this one crewmember who was high almost every day for work. The Chief mechanic (Superior officer) was about to get him dishonorably discharged for his drug use, well this stoner got too close to an intake vent of a jet.. and what was left of him was a long red streak down the tarmac and runway. This is why you keep a safe distance from active plane turbines kids.
Yeah Im friends with a former Air Force maintainace guy and I heard him tell a very similar story. He was a part of the cleanup detail and needless to say he did not go into great detail about it.
What an absolutely horrifying story. You had a lot of science to explain in this video, and you wove it in to the human story masterfully. Your selection of graphics and your editing are equally good. I don't know a better storyteller on YT. Thanks for your outstanding work.
Saturation diving seems like a pure nightmare fuel occupation. Not only this incident, but the story of Chris Lemons who got caught up in the North Sea and also Kazuta Harada who was saturation diving in Japan when he got attacked and eaten by a massive Great White Shark. Absolutely terrifying.
@@WillowWispFlame The issue with this is that Kazuta Harada was wearing saturation diving gear. Proper steel helmet and suit. No fins. The shark just saw an opportunity and took it.
Thanks for reminding me never to go diving i prefer to be on land than underwater if something potentially goes wrong at least i would have a better chance to escape from whatever predicament i may find myself in
Yeah, but 1000 bucks per day is kinda nice. Especially when you consider they work for a period, then they are free for the same amount or more. But yeah, its that much money for a reason...
Holy! I think I remember recommending this story to a community post you made years ago! This is such a terrifying and tragic accident. Puts the recent Titan submersible implosion into perspective. Byford Dolphin was a difference of 9 atmospheres, the titan submersible was a difference somewhere in the 350 - 400 atmospheres range!
My boyfriend works at a place that has a boat that had to get a special exemption to being found sea-worthy as it flips if more than one wave hits it. He luckily isn't assigned to that boat anymore (thank god!), and it hasn't gone out in a long time because things keep breaking on it (I suspect the employees are just constantly either claiming stuff is broken or actually breaking stuff to keep it in harbour because their employer has refused to retire the boat) but I always worry someday I'll hear it flipped. When it does, I'm sure you'll cover that they got an exemption to being sea-worthy...as a boat. Sometimes I wonder if anyone at the Byford Dolphin or any of these other places also knew someday there'd be an incident.
I'd forgotten the name of the company. When I heard the words "diving bell," I started thinking, "oh, no... oh, no..." What a scary profession. Even on land, sitting in the pressurized chamber, hoping nothing goes wrong with the mechanisms keeping it pressurized, because you might die painfully.
You should make a video on the Alexander Kielland oil rig disaster! Truly a fascinating horror story which had major implications for the then-future of oil drilling in the North Sea. The accident is fairly well documented on Wikipedia, and the accident report was released to the public.
I've largely given up on PD since he seems to have given up on editing the voice track or doing multiple takes. I'd definitely second Scary Interesting though and will have to check out Disasterthon sometime.
I remember reading about this but since I'm not familiar with the diving profession the details went right over my head. Your dialogue and visuals made it much clearer. Now I get it. A split second. That's all it took. I'm surprised even one person survived! I'm glad he did. Poor guy, the survivor's guilt must've been strong. Your viewership has always remained super strong! All due to your fantastic way of delivering content. I've subscribed to your channel for years (8?) and love it as much now as I did then. Shout out to you for being so popular, having a steady stream of subscribers, and being consistent in your greatness!🏆🏅 Take care of yourself!🙂
After multiple channels gleefully covering the Paria tragedy, it's nice to know I can learn about things here without worrying about gruesome "last moments" footage or pictures.
Your telling of events was extremely respectful of those involved. Some people covering this are quick to blame the crew for making “obvious” mistakes without thinking about how they’d react at the end of 12 hour shifts.
Man.......I gotta say, the things I learn from this channel about the dangerous stuff people do for a living and then of course the horrible consequences of a simple mistake or lapse of judgement just one time and how unforgiving it can be. RIP to those who passed from this accident. It is nice to see that improvements and other forms of technologies are providing a safer work environment......I'm pretty sure you couldn't pay me enough to do this kind of work.........matter of fact, I know you couldn't pay me enough to do this.......brave souls!
Thank you for not going into gory details. I’ve seen this story covered by other people who go in detail about the gore and will even show gory pictures. Which some people are into that but it’s nice having someone who covers tragedies without the gore
Thanks for this detailed and informative documentary about Byford Dolphin Accident. I've heard this workplace accident before but I didn't exactly understand how it happened.
This has freaked me out for decades and I have have tried to "unsee" it since the first time I learned about it. Every time I manage to forget, something somewhere mentions it. It's like losing The Game.
I think this video alone shows your main focus really is on lessons learned from these accidents. The other videos I've watched about this go into a lot of detail, sometimes too much detail, about what happened to Hellevik. Just seeing the animated recreations there are out there is such a horrific sight. I won't lie I do have some morbid curiosity like I think most people do, but sometimes the videos I get recommended are clearly just meant to grab your attention by shocking you with the most disturbing titles and thumbnails. I've been watching your videos for a few years now and they're always the most interesting and respectful. Keep up the great work!
Great episode! RiP the divers and the tender. All underwater stories affect me more than other incidents... absolutely terrifying. Hoping to see a "The Abyss" April's fools episode next year!
Yes, I am one of those people who had to find the photos. Astonishing, unbelievable, perturbing... don't begin to describe this nightmare event. I hope these men's brains truly had no time to register anything. Thanks, FH.
I heard about this event and have been trying to avoid seeing videos about it. It was such a horrific event. At least I knew you would cover more respectfully than must channels that have covered it.
There are three things in this world I never want to see - the full Station Nightclub fire video, the Tom Pryce F1 crash video, and the images of the aftermath of this. I've watched more than a few videos about this on RUclips over the years and it's still the most horrific accident I've ever come across.
Hard to watch some early F1 drivers caught in a fully loaded (fuel) unable to get out. Add in niceties like hay bales & magnesium body ensured a full burn
The Tom Pryce crash is insane. I wouldn't call myself squeamish by any means but a few months back, after watching a video that mentioned it but didn't show the full clip, I decided to look it up out of curiosity and jesus christ 💀 such an awful thing to happen to both of them but that marshal was only 19, poor kid
The design of the pressurized habit and diving bell were obviously inadequate for the transfer task. That system shouldn't have been allowed in 1983. That it took 26 years to resolve the lawsuit is also ridiculous, families that depended on the income were probably severely affected.
I work in a hospital with a hyperbaric chamber, and we treat divers with the bends fairly regularly. It's a fascinating bit of kit (came from the old Royal Navy hospital at Haslar when it closed) and is used for all sorts of other things as well. But having been involved with the treatment of afflicted divers it's something i never want to have to go through myself.
I first learned about this accident when I was in the navy, it was used as a warning for differential pressure, also known as Delta-p. This describes the phenomenon when water or air rushes through a narrow gap in order to equalise, because of the pressure is greater on one side versus the other, there's a well known video online of a crab, being sucked down fissure in a pipeline at 1828 metres (6,000 feet), it's a scary reminder of the danger of Delta-p. What happened on the Byford Dolphin was very much a freak accident, I cannot imagine how ghastly it must have been seeing human remains strewn all over the rig, never underestimate the danger of Delta-p.
Years ago I ran across some of the pathology photographs from the incident. It was more horrific than most people can comprehend. Closer to being squirted through an opening like a tube of toothpaste that was run over by a truck. The only mercy was that it was over so quickly for them.
To be perfectly honest, I think using robots in general to do dangerous work that humans normally do can save many lives across all industries that have dangerous work environments.
I find your videos to be very interesting and informative and you go the extra mile, visiting the locations, museums and animating the story. Wow so much work, but honestly it’s worth it as it’s fascinating. I knew nothing of the history of the things you cover now im subscribed to several channels covering similar stories but honestly yours are the best by far.
This is one that has always freaked me out as far as just what and how it happened, and just how fast it happened as well. It infuriates me about how the rig owners got an exemption, though I am glad post accident the exemptions were very swiftly rescinded however
even with all the other stories you've covered this one is still the most disturbing imo. I first learned about it when I was a kid and whenever I think about it I get a shiver up my spine. what an awful way to die.
Bless our men that do these insane jobs❤. They deserve $1k a day for this. I couldn't do this. RIP to these poor guys. How horrible to die this way😢 You are definitely one of the best disaster documentary channels. Thank you.
watched and read a good handful of pieces covering this incident, still absolutely love the organization and concise explanations and visuals you put together for these things. love to see it, in that peculiar way one learns from things that go wrong. thank you so much.
I've been a long-term fan of this channel, but this is the first I've seen based on saturation diving. Some great information is provided here, and diving is made understandable to those who aren't familiar with anything deeper than recreational diving... Dive talk would be proud
I was a commercial diver for 6 years. People always say, "Wow that's so dangerous." I always say that a lot of people had to die to make the industry as safe as it is today.
there are actual gruesome photos of Hellevik's body from the investigators as in his body is shredded to pieces like he went through a kitchen blender, dear god.
I'm so glad you covered this one, it's sort of a special interest of mine - mainly because the forces involved in pressure are absolutely fascinating to me. You wouldn't think a simple term like "depressurizing" could involve such violent physical forces.
For anyone interested, you can read an entry regarding the autopsy of those involved in this incident published in the American Journal of Forensic Medicine and Pathology (search "an explosive decompression accident"). FH also has a link to it in the description. Please note there are graphic photos of the bodies, including what remained of Hellevik. To say he "exploded" is accurate. It's absolutely wild that new safety measures weren't enforced retroactively. If something is identified as dangerous and/or a new measure put in place for new buildings or work practices etc etc it should apply to existing ones as well. This sort of accident would have happened sooner or later, it's really sad.

If businesses can cut corners, they will, whatever the cost... that is, until someone gets killed or seriously injured, and they get slapped with an expensive lawsuit, which ends up costing them more than cutting corners anyway. If you expect people to do dangerous work, then it behooves you to spend accordingly. But since too many businesses end up skimping on safety, "nanny gubmint" regulations are necessary to make sure said businesses do everything possible to ensure safety, both to employees and consumers.
@jrneal1220 there's only so much you can be spoon fed in life, that was a critical part of the job and that person wasn't paying attention. It's that simple
@@23Butanedione They were being made to work until 3 am, in extreme conditions. They were all working overtime, exhausted, in a stressful, isolating location. The equipment for communication was sub-par. The idea that people are infallible, and that if a mistake is made when being put in such intense situations that it's on them is asinine. Especially since there had been developments that made such errors impossible to make.
Individualistically, yes, the man who removed the clip was responsible. But the idea that that's as far as investigations go is genuinely just childish thinking. We should want things to improve. And when we have things that make that happen literally infront of us (I.E. significantly better equipment and processes), choosing to ignore them and shrug is a dereliction of responsibilities.
@@23Butanedionethere's several reasons listed in the video as to why the inner door wasn't closed in time, and why the outer one was assumed fine and opened, all in quite comparable ways people have occasional brain farts at any other job, or people get complacent about how things need to be done and what can be skipped etc because they've been doing the job years and haven't had a problem doing it a certain quicker way, *so far*. It's established here (and in other videos that have covered it, Well There's Your Problem goes into a lot more gory detail) that the company not bothering with/not being interested in putting money into safety features to match the potential risks meant it was inevitable, it just needed more than one small mistake to happen at once.
People "not paying attention" happens several times a day for a second or two at a time when you're on autopilot from habit, or having just done a 12+ hour shift as they had, etc. It's fair to suggest the consequences for that don't mean you and your workmates are instantly killed.
The details of this incident will always creep me tf out with how fast the incident happened.
Yes, the absolutely instantaneous rapid decompression and the damage done is a marvel of the power of the forces of physics and how fragile the human body is.
Yeah it’s hard to remember sometimes but the timing was literally “everything is fine no wait everyone is dead.”
they were under pressure to complete the job as cheaply as possible.
@@MarkJoseph81 the human body is also incredibly resilient. but it does take surprisingly little to make us unalive.
Sounds a bit like the diving apparatus (looking for Titanic) that imploded about a year ago.
Thank you for giving so much detail.
Before this I'd only heard versions that eliminated the extremely limited communication between the divers and the tenders made even worse by terrible weather and cacophonic noise.
Those versions with such limited information left the impression that the tenders were reckless fools. Now I know they were very tired men doing a hard and hazardous job with insufficient communication and safetly equipment and under extreme environmental conditions.
You do a great service to all the victims of this horrific accident, the tenders included.
I don't think I'd heard those details before either. I'm pretty sure other videos I'd seen on it did say it was likely a mistake from miscommunication, but they didn't really go into the conditions that would have contributed.
@@littlebear274 quite often fatigue from longs hours is the direct cause of industrial acidents
Yeah, lots of channels are more worried on describing in gruesome detail what happened to their bodies than give a proper context to the tragedy. RIP unfortunate divers.
Nothing like 10-15 minutes of disaster retelling to help me fall asleep
Meanwhile on the other side of the globe I'm listening to this while I'm getting ready to go to work
You and me both...
@@jacobboggs71at the end of your shift, I'll be getting ready for mine
Sweet dreams

It's always surreal to really think about how tiny mistakes can have such instantaneously catastrophic consequences. When you do a job, you are constantly aware of the simple things that are huge mistakes in context, but you never really think about how little and easy those the actual action of those mistakes are.
Yep, I've worked on the trains for 30yrs. When I was a young apprentice, I remember not putting the signal casing on correctly (basically rushing). Thankfully my supervisor noticed it, I got the biggest bollocking ever, it was probably the best thing to happen to me, since then I double check everything. It's often small mistakes that can have disastrous consequences.
Yeah, I find it weird to think about too. I feel like, psychologically speaking, it's kinda the same as forgetting to turn off the TV before you leave the house, a simple momentary slip, but the context has vastly different consequences.
@@artfulscruffabsolutely ridiculous comparison, it is NOTHING like forgetting to turn the tv off
@@artfulscruffif you are working an important job and you are going "la deda deda" not paying attention to critical components for the job and treating them the same as "forgetting to turn off the tv" then you are a liability
@@23Butanedione I think you misunderstand the point being made. It's the idea that it's something as small as that can lead to huge, disastrous consequences. If you leave your TV on, all you get is a slightly bigger energy bill. But in these extreme working conditions, something small LIKE that could lead to deadly results, depending on what it is you fail to do.
Certain jobs require extreme levels of vigilance, and things that would look meaningless to laymen and outsiders, could be the difference between life and death to specialists.
Something that often gets left out is the fact that both the divers and tenders were at the tail end of a VERY long shift - they were fatigued and all wanted to get the process of transfer over with quickly. Add the noise, no good indicator system and no failsafe, this kind of tragedy was inevitable. The force of 9 atmospheres spontaneously decompressing is comparable to a shot from a 19th century artillery cannon. The diving bell didn't just fall away - it became a giant cannonball, and the tender that removed the clamp was right in the path of it.
The three things they needed and completely lacked were interlocking failsafes, indicators, and checklists. They didn't even have a decent checklist to run through, and as the aviation industry can tell you, checklists are vital to operate complex equipment whose controls must be used in sequence. Even a checklist that told them to double-check the status of the inner hatch before unclamping might have prevented the accident.
It never was the tender's fault, though he got most of the blame. The ultimate blame lay with the Dolphin company, for operating a rig out of code with no safety failsafes and pushing their diving crews for illegally long shifts. The divers, at least, passed away instantaneously, though the details of what happened to Hellevik are best left to the imagination.
If you want a deeper look (no pun intended) into the world of saturation diving and its dangers, the excellent documentary "Last Breath" goes heavily into it, including a situation nearly as perilous as this one.
Fascinating Horror's concise and informative style of explaining these tragedies lends itself well to being shown in the workplace for safety lessons. It should be.
And they should be shown to shareholders and leadership to remind them that cutting costs and ignoring safety regs will result in them being featured on this channel.
@@gcopeland442 100% Agreed
YES!! How do we advocate for that??
Whenever I watch one of these videos I am in Health and Safety mode for several days
@martinhsl68hw Sometimes I hear the theme music in my head when I'm thinking of doing something stupid
It took 26 YEARS for the families to get a settlement?!! Ridiculous!!!!
Based on other stories on this very channel, that almost seems fast. There's so many where they're obviously owed something and they're either still fighting decades later, or they just got nothing.
There are glaciers that move faster than justice.
@@hellomark1 That is usually in cases with hundreds of victims and a payout of either hundreds of millions, or even billions, it's actually very rare for a handful of families to have to wait a quarter of a century for closure.
I was looking for this comment. That is the real tragedy here: the families got the settlement nearly 30 years later.
It’s a legal system, not justice 😍
That incident really gives me a hibby-jibby as they died from decompression and one forcibly sucked out after the Diving Bell blasted off.
And what’s even worse is that the “guy who got sucked out” got sucked through the door leading to the diving bell.
Which is already bad enough but the door was NEARLY closed. There was only a sliver open.
Just the mental image of a fully grown human being instantly sucked through a gap the size of a dinner plate
Yup that was the story alright
* heebie-jeebies
If you search in forbidden places on the internet, you can find pictures of the guy's guts floating in the water.
@@DustWolphy How would you ever possibly know if they were the same guy's?
Pressure is a scary thing. You're better off in a decompressing spacecraft than a decompressing diving chamber. If a steamship has a steam leak the way to find it is by waving a broom handle around until it gets sliced off, by all accounts as effortlessly as a lightsaber through butter. These are the sort of workplace safety videos we need.
One of those avoidable disasters where best things you can say about it, outside of the sole survivor, is that everyone at least died instantly and that it's an excellent bad example.
This is by far the best description I've seen of this accident. Most pay short shrift to the technical details and focus instead on the shockingly gruesome nature of Hellevik's injuries.
This is by far the best explanation I have ever heard of this incident. I've researched this before, but I don't feel like any other source has adequately explained nitrogen saturation or decompression sickness and you explained the results of explosive decompression so much better than I've ever heard before, and I've had to learn this for work. Excellent video!
Thank you for NOT including any pictures of the poor diver who was forced through the open door. There are images out there but they are extremely graphic and gruesome. This incident revealed a strong need for a better system of handling diving bells like this. It’s absolutely ridiculous that it took over two DECADES for the families to be compensated by the government for such negligence.
Just unfortunately saw one as I was googling the incident. I will never be the same again
@@sketchyskies8531 it’s awful. I’m just thankful it was instantaneous and he felt nothing.
Im glad they didnt share any pictures. The aftermath doesnt even look human
He never shows pictures of bodies and gore. It's one of the things that makes his channel so watchable.
Whilst in some senses it seems bad that such images are out there, graphic images of workplace accidents are sadly the only way to get the message through to some people. However, such images on the internet should always be behind a warning.
Thank you, FH, for always giving thorough rationale for correct procedure so we can understand what went wrong.
Thanks FH for tactfully and respectfully describing the physical devastation of those men. The reality was far more extreme and gruesome than you let on! Awful story but it taught some important lessons!
yes! if you google the accident, you'll find photos of what was left of the....um, victims.
One of those classic cases which just make you wince.
I love the respectful, unsensationalized way you present these stories. Tragic as they may be, I find it fascinating to examine precisely what happened in these situations, what the outcomes and lessons learned were, and appreciate the concise, factual analysis your documentaries provide without the use of unnecessary shock value or graphic imagery. Excellent work as always, FH.
Does not matter how many times you hear this story, it's still one of the most gruesome accidents ever and it never gets less impressive to hear the details and dangerous of sudden decompression. At least the guys were gone fast and instantly without suffering.
I’ve never looked favorably upon the use of robots to replace people in the workplace. In this instance, however, I see the wisdom of doing so. This was a terribly tragic accident.
Robots being used to do dangerous jobs is definitely one of the exemptions I give. Robots making my food at McDonald's? No. Robots performing bomb disposal? Yes.
What's wrong with robots making food at McDonald's? Low skill labor is prone to mistakes. Robots make less mistakes@@randomlyentertaining8287
The moment when Hellevik's body was ejected reminded me of a story of the most shocking event my dad seen in his 4 yrs of USAF service as an equipment mechanic (layman's terms, he fixed the machinery that helped fix the jets), There was this one crewmember who was high almost every day for work. The Chief mechanic (Superior officer) was about to get him dishonorably discharged for his drug use, well this stoner got too close to an intake vent of a jet.. and what was left of him was a long red streak down the tarmac and runway. This is why you keep a safe distance from active plane turbines kids.
"almost high"? So he was just buzzed?
Yeah Im friends with a former Air Force maintainace guy and I heard him tell a very similar story. He was a part of the cleanup detail and needless to say he did not go into great detail about it.
Thanks for sharing. I think....
As horrific as that is, all I can hear is Edna Mode going "no capes!!"
@@PaleHorseShabuShabu I meant high Almost every day
This is my favorite channel for this type of content. Many try to mimic your storytelling style, but none can match it.
What an absolutely horrifying story. You had a lot of science to explain in this video, and you wove it in to the human story masterfully. Your selection of graphics and your editing are equally good. I don't know a better storyteller on YT. Thanks for your outstanding work.
Saturation diving seems like a pure nightmare fuel occupation. Not only this incident, but the story of Chris Lemons who got caught up in the North Sea and also Kazuta Harada who was saturation diving in Japan when he got attacked and eaten by a massive Great White Shark. Absolutely terrifying.
Bro what, everything I've ever heard said sharks will not bother with unnatural prey and now I find this out? Nah man, nah
@@Beardqt the fins divers wear on their feet to move around faster look remarkably like the tail of a seal to a great white
@@WillowWispFlame oh no
@@WillowWispFlame The issue with this is that Kazuta Harada was wearing saturation diving gear. Proper steel helmet and suit. No fins. The shark just saw an opportunity and took it.
@@Beardqt It's unusual, but does occasionally happen. Great Whites are one of the species that are a little more likely to attack humans.
Thanks for reminding me never to go diving i prefer to be on land than underwater if something potentially goes wrong at least i would have a better chance to escape from whatever predicament i may find myself in
Yeah, but 1000 bucks per day is kinda nice. Especially when you consider they work for a period, then they are free for the same amount or more. But yeah, its that much money for a reason...
They were essentially 'on land' when this disaster happened tho...
Imagine thinking these men WANTED to go diving
@@GnosticAtheist$1000 is practically chump change
Add to that, stay on land and out of confined spaces. :)
Holy! I think I remember recommending this story to a community post you made years ago! This is such a terrifying and tragic accident.
Puts the recent Titan submersible implosion into perspective. Byford Dolphin was a difference of 9 atmospheres, the titan submersible was a difference somewhere in the 350 - 400 atmospheres range!
Ive heard this story told a hundred times. It never stops being terrifying.
My boyfriend works at a place that has a boat that had to get a special exemption to being found sea-worthy as it flips if more than one wave hits it. He luckily isn't assigned to that boat anymore (thank god!), and it hasn't gone out in a long time because things keep breaking on it (I suspect the employees are just constantly either claiming stuff is broken or actually breaking stuff to keep it in harbour because their employer has refused to retire the boat) but I always worry someday I'll hear it flipped. When it does, I'm sure you'll cover that they got an exemption to being sea-worthy...as a boat. Sometimes I wonder if anyone at the Byford Dolphin or any of these other places also knew someday there'd be an incident.
Thank you in your telling of this historic accident. Unfortunately, we learn more from our accidents than we do from our successes.
Been religiously watching your content every Tuesday morning for over a year now, and it is one of the highlights of my week
I'd forgotten the name of the company. When I heard the words "diving bell," I started thinking, "oh, no... oh, no..."
What a scary profession. Even on land, sitting in the pressurized chamber, hoping nothing goes wrong with the mechanisms keeping it pressurized, because you might die painfully.
That's why they earn the Big Money.
Well, in this case they died instantaneously, but in Hellevik's case they had to keep the casket closed at his funeral...
I don't think any amount of money could make me go into that death trap. Fuck all of that.
@@zurirobinson2749 Ditto.
You should make a video on the Alexander Kielland oil rig disaster! Truly a fascinating horror story which had major implications for the then-future of oil drilling in the North Sea. The accident is fairly well documented on Wikipedia, and the accident report was released to the public.
Yayy another video! You and John (Plainly Difficult) are amongst my favourite RUclipsrs
Disasterthon is pretty good too
I wonder if they have arranged to post on different days just to keep us from getting withdrawal symptoms.
So is Scary Interesting!
I've largely given up on PD since he seems to have given up on editing the voice track or doing multiple takes. I'd definitely second Scary Interesting though and will have to check out Disasterthon sometime.
I've heard this explained so many times, but your explanation was the best by far!
I remember reading about this but since I'm not familiar with the diving profession the details went right over my head. Your dialogue and visuals made it much clearer. Now I get it.
A split second. That's all it took. I'm surprised even one person survived! I'm glad he did. Poor guy, the survivor's guilt must've been strong.
Your viewership has always remained super strong! All due to your fantastic way of delivering content. I've subscribed to your channel for years (8?) and love it as much now as I did then. Shout out to you for being so popular, having a steady stream of subscribers, and being consistent in your greatness!🏆🏅 Take care of yourself!🙂
After multiple channels gleefully covering the Paria tragedy, it's nice to know I can learn about things here without worrying about gruesome "last moments" footage or pictures.
Your telling of events was extremely respectful of those involved. Some people covering this are quick to blame the crew for making “obvious” mistakes without thinking about how they’d react at the end of 12 hour shifts.
Man.......I gotta say, the things I learn from this channel about the dangerous stuff people do for a living and then of course the horrible consequences of a simple mistake or lapse of judgement just one time and how unforgiving it can be. RIP to those who passed from this accident. It is nice to see that improvements and other forms of technologies are providing a safer work environment......I'm pretty sure you couldn't pay me enough to do this kind of work.........matter of fact, I know you couldn't pay me enough to do this.......brave souls!
Thank you for not going into gory details. I’ve seen this story covered by other people who go in detail about the gore and will even show gory pictures. Which some people are into that but it’s nice having someone who covers tragedies without the gore
This is THE case to hear for anyone even beginning to think 🤔 “Hey, maybe all that decompression stuff is a bit unnecessary “ 🤦♂️
Thanks for this detailed and informative documentary about Byford Dolphin Accident. I've heard this workplace accident before but I didn't exactly understand how it happened.
This is the best video I've seen so far covering this incident. The illustrations really put it into perspective.
Indeed, and he also included more photos from the official report which is very helpful to the viewers.
This has freaked me out for decades and I have have tried to "unsee" it since the first time I learned about it. Every time I manage to forget, something somewhere mentions it. It's like losing The Game.
I think this video alone shows your main focus really is on lessons learned from these accidents. The other videos I've watched about this go into a lot of detail, sometimes too much detail, about what happened to Hellevik. Just seeing the animated recreations there are out there is such a horrific sight. I won't lie I do have some morbid curiosity like I think most people do, but sometimes the videos I get recommended are clearly just meant to grab your attention by shocking you with the most disturbing titles and thumbnails.
I've been watching your videos for a few years now and they're always the most interesting and respectful. Keep up the great work!
Great episode! RiP the divers and the tender.
All underwater stories affect me more than other incidents... absolutely terrifying.
Hoping to see a "The Abyss" April's fools episode next year!
Yes, I am one of those people who had to find the photos. Astonishing, unbelievable, perturbing... don't begin to describe this nightmare event. I hope these men's brains truly had no time to register anything. Thanks, FH.
I heard about this event and have been trying to avoid seeing videos about it. It was such a horrific event. At least I knew you would cover more respectfully than must channels that have covered it.
There are three things in this world I never want to see - the full Station Nightclub fire video, the Tom Pryce F1 crash video, and the images of the aftermath of this. I've watched more than a few videos about this on RUclips over the years and it's still the most horrific accident I've ever come across.
Jesus Christ, mate. Tom Pryce... Watched it on a sports recap TV show as a wee lad with my dad decades ago. The absolute stuff of nightmares.
Hard to watch some early F1 drivers caught in a fully loaded (fuel) unable to get out. Add in niceties like hay bales & magnesium body ensured a full burn
The Tom Pryce crash is insane. I wouldn't call myself squeamish by any means but a few months back, after watching a video that mentioned it but didn't show the full clip, I decided to look it up out of curiosity and jesus christ 💀 such an awful thing to happen to both of them but that marshal was only 19, poor kid
Your narration is so good!
The design of the pressurized habit and diving bell were obviously inadequate for the transfer task.
That system shouldn't have been allowed in 1983.
That it took 26 years to resolve the lawsuit is also ridiculous, families that depended on the income were probably severely affected.
as he said in the video, it WASNT allowed. just for some reason they were exempt from the law...
@@dyamonde9555 I'm saying it should not have been allowed to begin with.
I work in a hospital with a hyperbaric chamber, and we treat divers with the bends fairly regularly. It's a fascinating bit of kit (came from the old Royal Navy hospital at Haslar when it closed) and is used for all sorts of other things as well. But having been involved with the treatment of afflicted divers it's something i never want to have to go through myself.
I first learned about this accident when I was in the navy, it was used as a warning for differential pressure, also known as Delta-p. This describes the phenomenon when water or air rushes through a narrow gap in order to equalise, because of the pressure is greater on one side versus the other, there's a well known video online of a crab, being sucked down fissure in a pipeline at 1828 metres (6,000 feet), it's a scary reminder of the danger of Delta-p. What happened on the Byford Dolphin was very much a freak accident, I cannot imagine how ghastly it must have been seeing human remains strewn all over the rig, never underestimate the danger of Delta-p.
That crab video must have been the inspiration for the part in Aliens 3 where it gets sucked out of the spacecraft through a one inch hole
Delta P is utterly horrifying... literally the only blessing is at least it was quick.
When it's got you it's got you 😂
26 years?!?!? That’s longer than most prison sentences.
Thank you for your hard work on your videos , i learn so much watching them .
Years ago I ran across some of the pathology photographs from the incident. It was more horrific than most people can comprehend. Closer to being squirted through an opening like a tube of toothpaste that was run over by a truck. The only mercy was that it was over so quickly for them.
Even though the death toll here was much lower than in your other documentaries, this one feels especially grim for some reason.
Thank you for cleaning up what happened and putting it in a way gently enough for me to listen.😢
Tuesday mornings never disappoint
Thank you for not including the image of the aftermath, even blurred. I stumbled across it once on the interwebs and that shit haunts me to this day.
To be perfectly honest, I think using robots in general to do dangerous work that humans normally do can save many lives across all industries that have dangerous work environments.
I find your videos to be very interesting and informative and you go the extra mile, visiting the locations, museums and animating the story. Wow so much work, but honestly it’s worth it as it’s fascinating. I knew nothing of the history of the things you cover now im subscribed to several channels covering similar stories but honestly yours are the best by far.
This is one that has always freaked me out as far as just what and how it happened, and just how fast it happened as well. It infuriates me about how the rig owners got an exemption, though I am glad post accident the exemptions were very swiftly rescinded however
FIrst time hearing about saturation diving. Dangerous work, indeed! thank you for the content.

even with all the other stories you've covered this one is still the most disturbing imo. I first learned about it when I was a kid and whenever I think about it I get a shiver up my spine. what an awful way to die.

watched and read a good handful of pieces covering this incident, still absolutely love the organization and concise explanations and visuals you put together for these things. love to see it, in that peculiar way one learns from things that go wrong. thank you so much.
There was a Mythbusters episode that demonstrated what can happen with such a change in pressure ... disturbing!
Somewhat revealing like when a railroad tank car is depressurized and is literally crushed like a tin can by "simple" atmospheric pressure.
I’ve watched many vids on this incident and your vid is by far the easiest to understand exactly what went wrong. Thank you! 😊

The chart was much appreciated! Helped to "see" what happened.

As always thank you so much for such a wonderful video with so much detail and respect for those who it occurred to!
I recommend looking into the Alexander Kielland rig disaster too.
I was a commercial diver for 6 years. People always say, "Wow that's so dangerous." I always say that a lot of people had to die to make the industry as safe as it is today.
The pictures of the hyperbaric chambers have my claustrophobia going crazy...
You always had quality content. Plus, it's understandable and very well presented. Thank you.
there are actual gruesome photos of Hellevik's body from the investigators as in his body is shredded to pieces like he went through a kitchen blender, dear god.
Yeah I've seen them too, not pretty at all 😭
I've seen those. It takes a minute for your brain to process what you're seeing, then its like 😮
To anyone curious about the picture, I must implore you, it is NOT WORTH THE SEARCH. I AM ABSOLUTELY SERIOUS
Absolutely horrifying.
@christopherbartsch9390 I’ll definitely not be looking for the photos. The descriptions in the comments is graphic enough for me.
I'm so glad you covered this one, it's sort of a special interest of mine - mainly because the forces involved in pressure are absolutely fascinating to me. You wouldn't think a simple term like "depressurizing" could involve such violent physical forces.
Makes you realise how difficult it will be to adapt to conditions on other planets, if we ever get that far.
This is one of the most horrifying incidents you have ever covered, but as always, well done.
Delta P is an existential horror
When it's got you, it's got you.
For anyone interested, you can read an entry regarding the autopsy of those involved in this incident published in the American Journal of Forensic Medicine and Pathology (search "an explosive decompression accident"). FH also has a link to it in the description. Please note there are graphic photos of the bodies, including what remained of Hellevik. To say he "exploded" is accurate.
It's absolutely wild that new safety measures weren't enforced retroactively. If something is identified as dangerous and/or a new measure put in place for new buildings or work practices etc etc it should apply to existing ones as well. This sort of accident would have happened sooner or later, it's really sad.
I hit like before the video even started 😅
I felt an immense sense of dread as soon as I heard the words “diving bell.” Such a horrific way to go.
