indeed. My grandfather knew a couple who had an accident while loading produce that led to OSHA changing dock safety procedures nationwide. Driver Couple had gone to pickup lettuce, wife went missing during loading and wasnt found by the time they had to leave, So the husband delivered the load while the police searched for the wife. When he arrived they were unloading the produce when they found her. She was pressed up against the front pallet in the trailer. A forklift apparently was not aware she was in the trailer and drove a pallet of Lettuce into the trailer, killing her. Man drove 3 states with his wife in the back. Now they have a whole set of procedures in place to prevent another incident like that.

However, if you're mechanic or technician of some sort, and you're doing maintenance on (for example) the tower's, then it's a whole different ball game. The person moving the lift is communicating with you by radio (sometimes in a control room miles away). You may be clipped into a specialized chair hanging from the wire while simultaneously clipped to the tower that you are working on (in order to prevent a fall). If the lift moves during this point in the operation then you're harness will be pulled in two separate directions. Most lift tech's I know are extremely picky about who operates the lift when they are out on the wire. Luckily the mechanic that day unclipped before the wire moved. I was never put at the controls of a work chair again and I've since left the business.

I remember when this happened. I was in grade 11 at the age of 16. When it was first reported in the news, no details were given. It took some time before they told that it was massive depressurization that killed them. Since the average person knew next to nothing about diving bells, we just pictured what happens on a plane during cabin depressurization, so our imagination pictured something vient, but nothing like the reality of it. Not until my senior year in 1985 did my friends and me find out exactly what happened to these men. I remember how much it disturbed me because of how young and innocent I was. Now I'm 53 and have watched four people die in person in auto accidents, falls from great heights, and being crushed on a construction site. I am a Civil Engineer and so I'm routinely around huge structures being built. Bridges, dams, channel ways, water treatment plants, highway tunnels, etc., etc. Seeing all of what I've seen in my 35 years of adult life has maee me have a VERY healthy respect for just how fragile our bodies are in comparison to things we design and build. I've never designed anything that failed and killed people. I've never designed anything that failed, period. I hope and pray it stays that way. Those of you watching these videos at a very young age are learning things in an effective way because there's no better motivator to do things safely and to design things in a VERY careful and tested manner than seeing just what forces can do to our bodies in just a few seconds. Gruesomeness observed equals careful procedure and discipline in operations.

It’s important to note that it’s NOT the crew’s fault! Martin Saunders (the survivor) said himself that Crammond wouldn’t had unclamped the bell if he wasn’t certain it was pressurized. And even when it isn’t, the system should’ve locked and not opened. The crew was exhausted after working unethical and cruel hours (18 hours with 4 hours off, then 14 hours with 2 hours off, then 9 hours for the actual incident). It was entirely the company’s fault. They robbed the crew of their lives and Saunders of his sanity. Even after being disabled from the event, the Norwegian government treated it like it never happened and it took the British government 3 years to put Saunders on disability pension for only £200 a month. He then had to raise 2 kids with the oldest being a year old, a couple years later his wife fell very ill, forcing him to raise them alone (I’m not certain if his wife died or not). He went through hell because of that company, and they didn’t even care.

I guess that's why they have such a high salary.

I gotta clear something up because I went into a whole deep dive once I found out not everyone in this accident died: Martin Saunders, the man outside the bell chamber, sustained serious injuries and was found alive at the scene after the DP. Retrieval team hardly recognized him due to the injuries his face sustained, but he survived and was able to make a full recovery, and was able to clear up why Crammond opened the chamber door. Their company had been working these 6 men for days on 3 hours of sleep each 18 hour work day, numerous grueling hours of work each day spent reviewing equipment and undergoing pressurization. They were _tired,_ and Crammond and Saunders shared a look of confirmation with each other in order to communicate that yes the interior door was (believed) to be closed, as the timespan it normally took to close it had gone by. Yes, it was a problem with human error, but the reason why it happened was company greed. On numerous occasions their employers had even said if they weren’t up to the task they’d be let go and they didn’t want to lose their jobs despite the harsh conditions. Since then, the families of the victims have received compensation-but they had to form a committee that fought for 25 years for said compensation. Crazy corporate greed stuff

That was a pretty good explanation of the event, and I am glad you kept to a technical explanation rather than played up all the dramatic details. However.. at the time the guys inside the chambers were not decompressing, they were living at their holding depth which is about 10 meters less than the working depth. On this particular Comex system, after the dive, when the bell was locked on to the chambers, the divers put all the consumable items, like the sodasorbe canisters, silica gel canisters, old food and drink containers, along with their hot water suits and under suits into the trunking. The door of the bell was shut and the internal pressure of the bell slightly increased to hold it shut, then the divers in the transfer chamber shut their door. When they have confirmed the doors are shut, the dive supervisor bleeds the from the trunking. When the trunking is surfaced, the supervisor tells the deck crew to unclamp the bell and recover the gear in the trunking for cleaning or replacement. Notice that on this system, it is the dive supervisor who pressurises or depressurisation the trunking…and then tells the deck crew he has done so. On most sat systems of that time, there was a visible pressure gauge on the trunking, and it was the deck crew, who being able to physically see if there was pressure in the trunking, who controlled the pressure in the trunk by way of valves fitted to the trunking it’s self. You also miss the fact that the dive crew had already done one 18 hour dive with 4 hours off…followed by a 14 hour dive with 3 hours off and then the final dive of 9 hours after which the accident.. Everyone was completely exhausted.

Hi Martin, thanks for the explanation. I have seen many videos and articles on this and they all list 5 steps. Step 4 is that the pressure in the trunking is slowly lowered to 1 atm. However I don't understand why this is necessary because as we know detaching the diving bell immediately sends it to 1 atm. Can you explain? Everybody lists that step and I don't know if it is an error and everybody is copying each other. Sorry for what you had to experience. Hope you are doing well.

People who see aftermath photos of sudden decompression should take comfort in the fact that experts say the victims are dead in 2 milliseconds whereas it takes 4 milliseconds for the brain to comprehend pain or awareness.

What went through their minds?... In Crammond's case, the diving bell... In Hellevik's case, an awful lot of air... A relative of mine was on the Byford Dolphin that day. The diving bell was propelled across the decompression deck with such force that it was rendered inoperable and had to be scrapped. It also caused so much damage to the structure of the deck that the rig was out of service and in dry dock for many months having a major structural refurbishment. Had this happened on a diving support vessel, the ship would most likely have had to be scrapped due to the level of damage wreaked on the hull. The 4 unfortunate divers basically exploded, but death was so quick for them that their brains very likely didn't even have time to start registering pain... My relative left diving support work and moved to working on oil rig support vessels, being among one of the first crews to arrive on the scene of the Piper-Alpha disaster. Despite his qualifications in regard to deep sea diving he has no interest in ever returning to that field...

@Curiosity Huh.

Thank you for giving the names of those who lost their lives in the incident. They weren't nameless victims, they were people who put their lives on the line for their work. Industrial safety is usually paid in blood. If you're diving without a hard shell, the air you breathe has to be at the same pressure as the water pushing down on you or it won't be able to get into your lungs. At extreme depths you could have a few atmospheres of dissolved gas in your bloodstream. A slow ascent lets that dissolved gas equalize to the surrounding pressure in stages until the diver reaches the surface. In the Byford Dolphin incident, the ascent was instantaneous - the other divers further away from the trunk hatch died when gas instantly bubbled out of their blood, rupturing blood vessels and destroying internal organs.

I know nothing about Truls Hellevik, but I'm sure that he had his own journey like all of us did. He had his kindergarten friends, his loving family, his favorite music, his best friend, maybe even his lover or soulmate. He had his own story, he accomplished so many things in his life. I can imagine his first steps, his first words, his first day at school - and Truls' parents would be proud of him of how much his son has achieved. Every moment was a treasure for his parents. And something happened which Truls' nor his parents or friends have expected. His body destroyed completely in a matter of seconds, hence his beautiful life ended. What would they expect on that day? Maybe in the morning, Truls' would quickly say "bye mom" and quickly shut the door without giving her a kiss or a hug. His mom never knew, neither did he, that it was his last moment in his entire life. He was a living person who had his own story and journey, who had a family, who had everything what he could wish for. Because all we know is that we're living creatures on a floating rock somewhere. We don't know what, when or why the universe was created and what happened before. Our life is simply meaningless in the eyes of the big, big universe but our purpose is to live for ourselves. The little moments in our life, such as eating out with your family, the nights where you have a fun sleepover with your friends, the moment where you meet your first love ever and the bittersweet feeling of happiness and nostalgia. All of these moments our an impact of every single event of our universe, wether it was the big bang or your great-grand parents decidikg to have a child or your parents meeting that day. Every single choice which every human decides has an impact on everyone - the butterfly effect. Our life has so much potential, yet it is so fragile. A human body, or a human body could shatter and end in a short phase of seconds. Once that occurs, everything disappears. All the memories you had with them, are fully gone - whether it was listening their soothing voice, having fun with them or spending time with them. All of those little moments will never return and you won‘t experience them, no matter how hard you try. And if you didn‘t take a picture at that moment, then the memory will forever fade away into the nothing. So enjoy every second of your life, because you‘ll never know what will happen in the next seconds, minutes, days or months. No matter if you're Muslim, Christian, Atheist or Buddhist - you should accept that life is the biggest gift you received in your life, a once-in-a-lifetime gift which you can't give or receive again.

At least it was instantaneous. Back in my hometown, several children (in seperate incidents) were sucked through a tube at an outdoor pool that was only several inches in diameter - and one of those survived the incident with severe lacerations caused by organic growth on the inside of the pipe removing her skin (she was ejected onto a nearby beach and was taken to hospital and survived).

This is a partial list of the commercial diving fatalities over the past 15 years. All have one common cause, Delta P. Two out of three commercial diving fatalities involve Delta P. It is invisible to a diver and it strikes suddenly without warning there is almost no way to escape once it grabs you. Knowing what it is, where it lurks, and how to avoid its grasp is the subject of this video. Delta P stands for differential pressure. Our discussion refers to situations where the pressures between two bodies of water are dramatically different. In a situation like this, the bodies of water continuously seek to equalize themselves. In this example the body of water on the right wants to rush to the body of water on the left by means of the pipe between them. The pressure exerted on the valve stopping this water transfer can be enormous, depending on the difference in the depths of the water, and the diameter of the pipe. If the difference between the depth of water is 50 feet, and the diameter of the pipe is 10 inches, the force of water exerted on the valve is nearly 1,700 pounds. If the valve was suddenly opened, and your arm was near, it would be sucked into the hole instantly. Trying to remove your arm would be like trying to lift a car completely off the ground, with one hand. You could only remove your arm if the pressures between the two bodies became nearly equalized, but at the pressure in this example your body makes a perfect seal, stopping the bodies of water from equalizing. The formula for calculating the force of water through a hole at a particular depth is, the area of the hole multiplied by the difference in water depth multiplied by the PSI per foot of water depth. Or in the situation just described, the 10 inch hole equals 78 square inches times 50 feet of water depth times 0.432 psi per foot of fresh water depth, equals 1685 pounds of water pressure. If you are diving in salt water be sure to use 0.445 psi in your formula instead. You can't see or feel a Delta P situation as you dive near it. It grabs you suddenly and it doesn't let go until the pressure is equalized. When it's got you, it's got you. As you watch the following recreations of actual Delta P incidents, ask yourself if you have on occasion ventured into situations without being thoroughly prepared. Diver one enters the water behind the dam structure in order to clean the strainer of the dams drain. When the drain is cleared, the tremendous force of rushing water through the drain grabs hold of diver one, sucks him partially inside and traps him. Diver two enters the water to help divert one and becomes trapped also. Diver three enters the water to rescue divers one and two and after 40 minutes returns to the surface with both divers. They are dead. Diver three was hospitalized for injuries suffered in the rescue attempts. A scuba diver was repairing a pool bottom at a depth of 10 feet and he came close to the open pool drain and was drawn against it. His body made a perfect seal against the drain. He was diving alone, and had no tender at the surface. No one knew he was trapped. He ran out of air and drowned. Two scuba divers entered a water tower to unclog a drain. Using a fire hose to blast away the silt and mud that was clogging the drain, the drain suddenly opened. A great suction immediately occurred. Diver one was pulled into the drain. Visibility was zero. Diver two did not know that this had occurred. Diver two surfaced, thinking diver one had already come up. Diver two made repeated but unsuccessful attempts to find him. Diver one ran out of air and died. Neither diver was tethered to the surface, had communication with the surface, or with each other. A surface supplied diver was working offshore in 86 feet of water on a well reentry project. He was using a drill string to hook a trash cap, inside of a 13 inch well casing. The first attempt failed to catch the cap. The diver was asked to stand by the hole to make sure the string caught the cap. He reported when he saw the cap was hooked and began to leave. The drill string was pulled to the surface rapidly because the camp was nearly the size of the casing, a great suction developed. As the cap came free, the rushing water grabbed the diver and forced one leg into the hole up to the pelvis. The diver was killed. Diver one enters the water at a hydroelectric generation plant. His assignment is to seal off leaks in a large gate valve. The three-person dive team is assured by the plants operating personnel that the gate valve is closed. Diver one surfaces and reports that he thinks the valves are open. The winch is started and closes the valve. A 30 inch sluice gate is manually crank shut. The dive team questions the plant personnel. The valve indicator shows the valve not fully closed. Plant personnel replied that the indicator is never correct and typically the valve is cranked until tight Diver one re-enters the water, convinced that everything is okay. In a few moments he begins to scream. The dive supervisor tries to contact diver one on the intercom. The tender and supervisor pulled the lifeline and umbilical. Both have broken from their attached points. The gates are cycled open while waiting for the rescue divers. Two attempts by the company diver failed to locate diver one. 12 hours later, diver one's body is recovered. When you accept a new job, make sure you take part in a free job meeting. Be sure that you understand the layout of the site, and how the piping and valve systems work together. The diving supervisor should have a simplified, but site-specific schematic of the site and a diving checklist to make sure nothing is on or open that shouldn't be. Your client also needs to know about Delta P. If they take your concerns lightly, make sure they understand the life-threatening hazards. Always practice lockout-tagout procedures. These are tried-and-true methods that can eliminate machinery and valve accidents if practiced religiously. Make sure to consider the potential delta p hazards of your new assignment when choosing your equipment. Make sure others in the water and on the surface can tell exactly where you are. They should be able to communicate with you at all times and be able to get you out if you're stuck. Make sure your equipment won't interfere or become fouled if you must be near a delta P situation. There are certain techniques that you can use to help reduce and even eliminate delta p hazards. The first step is to recognize the potential forces working on each other in your environment. Learn the layout of the site and how the system functions. Calculate the force of water at the depth you're working based on the size of the openings at that depth. Instead of cutting holes to drain water or relieve pressure, cut slots. If your body or equipment can't make a good seal against the flow of water, you can't get stuck. Fabricate a cover for the drain that has a screen or make a cover that has more than one hole a good distance away from the other. The idea is the water can still get through even if your body gets in the way. The goal of this video is to make you aware of the potential for differential pressure situations. The key is to recognize them beforehand, and make sure you're prepared to deal with them. Because when it's gotcha, its gotcha. Don't add your name to this list.

KZread suggested this video because I’ve been watching videos about the Titan sub.

That is horrifying. I can't imagine there not being some kind of fail safe on that door.

It was an illegal diving operation, the government required a failsafe on all diving equipment for over a year, and the company did not comply, also they tried to shift the blame on the operators.

I like how well you explained what happened and the respectful tone given that multiple people died in a horrific way.

3:24 The most unfortunate last name

One of the finest and most well-produced accounts of this incident I have ever seen - straight to the point, an accurate description of the event, and no BS. Great job. As for the men who lost their lives, all we can be thankful for is that their deaths were probably very quick. I feel for their families.

After searching for a better explanation/understandable in layman's term, your video showed up exactly as needed. Nice!

ive read this case many times and couldnt get my head around the procedures, you made understanding this so much easier

didn't even watch yet, just love this series; hope to see more, just love the research & way you go over the topics at hand ! [ this happens to be a case i've always been eerily curious of; but unnerved deeply by ]

I heard the description of the aftermath, just chunks. The best way to describe what I've heard from my own thoughts would probably be 'tomato sauce', fine red paste with the occasional chunk. Horrific.

Beautifully explained and illustrated to easier understand what happened in this case. May those men RIP.

I remember reading this years ago and seeing the remains scarred me for life... just awful in a split second do go in that way in a place like that... just pure grim Great video!
