The Titan Tragedy

Oceangate Expedition lost communication with its deep diving 5-person submarine on June 18th 2023 while transiting submerged to the Titanic wreck site. 5 people onboard were: Stockton Rush, PH Nargeolet, Shahzada Dawood, Suleman Dawood, and Hamish Harding.
In this video I describe the incident in detail. I review the construction, design and system onboard the Titan. I catalog my concerns about the design and operation of this submarine. This video is my personal opinion with the limited information available to me at the time of this recording. A follow up video will be published when more facts from the investigation surface.
Titan is a Cyclops-class manned submersible designed to take five people to depths of 4,000 meters (13,123 feet) for site survey and inspection, research and data collection, film and media production, and deep sea testing of hardware and software. Through the innovative use of modern materials, Titan is lighter in weight and more cost efficient to mobilize than any other deep diving submersible. A combination of ground-breaking engineering and off-the-shelf technology gives Titan a unique advantage over other deep diving subs; the proprietary Real Time Hull Health Monitoring (RTM) systems provides an unparalleled safety feature that assesses the integrity of the hull throughout every dive. The use off-the-shelf components helped to streamline the construction, and makes it simple to operate and replace parts in the field.
Paired with a patented, integrated launch and recovery platform, Titan is easy to operate in varying sea states using a local appropriately sized ship for the project. In coastal waters this means we do not need a large support ship with a crane or A-frame.
Sourced from Oceangate.com and Teledyne interviews with the CEO Stockton Rush. This video is intended to provide my opinion on this event with the information available to me at the time of recording.

The more I read about this, the more I feel that this is basically deep sea Theranos. Look at the parallels: -both have a charismatic CEO who considers themselves an innovator but doesn’t have expertise in the field that they are trying to revolutionize (medical science and deep sea diving) -both are a start-up company with a ramshackle, “move fast and break things” atmosphere, even while working in a field that is complicated, dangerous, and where mistakes can actually jeopardize people’s lives -both ignored warnings from veterans in their field, claiming they were just threatened by newcomers and stifling innovation -both hired mostly younger engineers who were recent college grads, while firing employees who had concerns or wanted to take a more conservative approach -both threatened whistleblowers with legal action, claiming that they were sharing proprietary information about their new technology (when in reality they did not HAVE any new technology) -both claimed that they weren’t certified by regulators because their technology was too new and innovative so the usual testing methods were irrelevant for their machines -both used partnerships with legit companies to give validity to their technology, when in reality these claims were either entirely made up or very misleading (Pfiezer and St. John’s Hospital for Theranos, Boeing, NASA and University of Washington for Oceangate) -both overpromised on their tech and underestimated the time and expense it would take to actually make it workable, leading to delays, funding running out, and cutting corners (my opinion based on the fact that the original price for this trip was $80,000, and the couple who tried to sue for a refund after their 2018 trip was delayed 3 years in a row because the sub wasn’t ready, and how hard Stockton tried to get that Las Vegas financier and his son to go on the trip, right down to the last minute and even offered them a $100,000 discount) -both had a CEO who genuinely believed in their product and was capable of convincing others of their idealistic vision, but both were also so confident, over-ambitious and ego-driven that they wouldn’t hear opinions that conflicted with that vision Even their website reminded me of Theranos’s: flashy, full of marketing jargon and grand claims, but vague on details and no citations or scientific references to back up their supposedly groundbreaking technological advances. Elizabeth Holmes might not think so, but she was extremely lucky that she got busted before their shoddy blood tests actually killed someone. Unfortunately, Stockton Rush wasn’t, and instead he paid the ultimate price and took four others with him.

I hope St. Peter asks Stockton Rush "Was it worth it? Was it?!"

But being underwater thousands of feet you don't have a gas station you can go to and grab supplies.

[@raymondrobbins698]

I was a submariner, got out in 1986 as a chief of the boat. You are spot on regarding everything you said, I was thinking all of the same things you did plus a little bit more. Was there any pre dive procedure or checklist? What about post dive inspection procedure? How about scheduled maintenance? What about an emergency blow system or at least an ability to drop ballast? Did they ever conduct casualty drills or at least write procedures? It is clear that from the CEO on down they did not understand the complexity and dangers associated with diving in a marine environment. There is no rescue vehicle (DSRV), that could be on station before the air runs out, there is no DSRV that can mate with this thing due to the location of the 17 bolt door, and you would probably need some type of mechanical arm to remove the bolts. No such thing exists. As you mentioned, how did they know their air supply was adequate for 96 hours; was hyperventilation due to panic considered in that number? They will not be saved and most likely the submersible will never be recovered. It is ridiculous to believe the Coast Guard will find this thing with their sonar, it is too small a feature to be distinguished from the bottom profile with active sonar and there is not enough machinery noise (if any) to be heard passively above the surface background noise. (I am a sonar systems expert and was an instructor in the tactical training department at the Sub base in Groton, CT) One final thing, the media and just about everyone else are calling this vessel a submarine, it is not a submarine. Submarines are autonomous, this vessel is a submersible and requires a support ship to function. The ocean does not forgive.

The story of Stockton Rush is tragic, and poetically ironic. For some, it's completely outrageous and for others it's entirely comedic, but at least it ends with timeless lessons to reflect on. He forewent safety and the wisdom of expertise, knowledge, and caution, all for the sake of a childish dream, to cut corners, and mitigate costs. When one of his own people brought up the idea of valuing life, Mr. Rush allowed OceanGate to fire him. Then they sued the man and forced a settlement. They had previously advertised the Titan as meeting or exceeding the safety standard of DNV certification, despite never receiving, or even intending to receive, such a license. Over three dozen field experts expressed their safety concerns, and they were ignored. In a supposed attempt to foster the next generation of expert submariners and engineers, he blocked off the likes of people who may have learned something from the Kursk disaster. People who may have been taught by those who investigated the Thresher. He ignored an entire generation of people who could realize his own dream because he didn't like hearing how downright negligent and dangerous his approach was. He didn't learn a thing from space and aerospace. These fields are written and forged in the blood of dead men and women, and Mr. Rush chose to ignore the dead and let them go on in vain. I just cannot understand the arrogance and idiocy needed to throw out voice communication just because you don't like checking-in while performing one of the most dangerous activities ever conceived. To have no method of escape if you managed to surface. Thank you, Stockton Rush, for reminding and teaching people that safety and lives have no cost. That the new generation must be guided by the people that have been there and done that. I have no doubt Mr. Rush has succinctly implanted the concept of safety into his team now. You got to live your dream, pilot your little sub, and go down with your ship. As much as the man infuriates me, I respect that he put himself through the same reckless adventure as his passengers. The man had no fear of the deep in his little pillsub. I have no doubt he wholly believed The Titan was the next step in deepsea exploration and was revolutionary. Somehow that's scarier than if he knew how ridiculous The Titan was. Rest In Peace to the 4 people he brought down with him. I unapologetically wish OceanGate never recovers.

Check out the lawsuit from David Lochridge, former director of maritime operations for OceanGate who was fired for reporting safety issues. This sub wasn't just a deathtrap. It was practically intentionally designed to violently implode at those depths. The lawsuit (alleged) that the viewport was rated for a depth of 1,300 meters, while the sub planned to go down to 4,000 meters. That would definitely cause an implosion. He cites several other safety concerns in the lawsuit, like the inability to inspect carbon fiber for fatigue stress, which could have been the other likely cause of the implosion. The sub was a death trap.

[@lpr5269]

The thing was that Stockton's company was not insured and could never be insured. Every person who went on his sub assumed a risk that if something happens, your family will have no recourse. They knew this and went anyway. They had to sign a waiver of liability. So the fact that David Lochridge had concerns really didn't matter because Stockton classified his passengers as mission specialists. Lochridge actually voiced his concerns to OSHA in 2019 and they did nothing. So long story short. There was really nothing anyone could do.

[@messupfreq550]

Additionally, carbon fiber is great for aircraft pressurization hulls because the fiber is in tension (higher inside pressure than outside). The biggest problem with the Titan design is the fiber is in compression which is its worst strength direction thus the epoxy is providing most of the resistance, and from what I understand it was not autoclaved to eliminate voids between CF layers and was wound over top of itself. The choice of using a tube also means the greatest deformation occurs in the center of the longitudinal axis which adds a pulling strain vector from the titanium ends where it is glued toward the center of the tube. Probably Stockton thought the pressure on the titanium ends would compress enough to counteract the pulling, however the area of the tube is much greater than the end 'caps' area so the force is not balanced out, resulting in a 'tearing' vector at the titanium 'socket' / glue interface over time.

[@charliekelly735]

Great video! One mistake: The Titan DID previously make it to the Titanic several times (albeit with a replaced hull at one point) so it wasn't just a blind test using customers. Stockton's luck ran out. Still, he maintains full blame and is a fool for not listening to the experts.

Carbon fibre is great, until the moment it cracks. It also 'ages' a lot with every load cycle. Titanium is known for 'rot'. The window was not rated for the depht at all. The controller is from Logitech. Logitech had a long standing problem with their wireless unified receivers: after 30 connection events, the receiver died. And they did not thoroughly check the submersible after each dive. No x-raying for example. Just some 'knock&listen' tests. Some time ago a huge patch of the carbon fibre hull delaminated. You can't get out, without outside help. This thing is a death trap. but it gets worse: in previous tours they touched down on Titanic's decks and moved around between superstructure elements. In a carbon fibre hull under lots of stress. So... what happens if the deck gives away? What happens if some sharp edge is bumped? They used a death trap AND did idiotic stuff.

[@voltsoftruthBSbuster]

When they announced that they found the pressure hull of the sub in pieces that was the first clue that something was very different about this sub and there were probably flaws in the design. Then I saw them fabricate the hull I was shocked. Let me be frank and admit I'm not a structural, or naval engineer, however I do know a lot about how materials behave and fail under loads, excessive pressures, stresses and sudden forces. And even though you could create a much worse shape for the subs pressure hull, the shape they chose and material was not ideal and was perhaps flawed. Cylindrical shapes are strong but not strong enough for the pressures you are going to be exposed to 2 and a half miles under water. Every deep diving submersible like Alvin, Trieste, that was not military in nature have always utilized a spherical shaped pressure hull constructed out of Titanium or hardened steel sandwiched between two layers of Titanium and were typically 5-7 inch thick. Now a spherical shape is much stronger than cylindrical shape since it distributes the pressure equally around the circular shape, and yet even those pressure chambres were created from solid machined Titanium 5-7inch thick. This should immediately tell you a cylindrical shape made from the same thickness wouldn't be strong enough. Despite being the second best choice for preasure hulls, they are not ideal for extreme depth where there is no margin for error. One could argue it was made from carbon fiber which is stronger than Titanium and steel, however carbon fiber has its own flaws. First off if the fiber was not woven properly with upmost tight tolerance it will be defective and much weaker than even steel. Secondly Titanium and some medium carbon steels, are very ductile, extremely flexible, and can flex and deform quite a bit before rupturing. Titanium doesn't snap but almost tears like rubber and extremely tough, ductile metal. It will start to flex, bend and deform long before it completely fails, giving ample warning that the structural integrity of the vessel is jeopardized. Carbon fiber has non of those attributes. It will remain stiff and solid right up to the mili Second it fails and is crushed, never giving you any indication that your vessel is in trouble. Im sure the vessel had preasure guages and sensors monitoring the pressure exerted on the vessel, but those could, fail, give you false readings, or malfunction. There should always be a visual gadgets that are fail proof. The best technique is used by submariners maybe if he had a 50 year old male who served on a sub he could have implemented a simple device that perhaps could have saved their lives. Its a simple yet ingenious method of determining how much force is being exerted on your craft. A simple string (fishing line) or tight rope is secured to one side of the vessels wall and run to the other side of the wall. The string is tighten as tight as you can. Once the sub starts to dive, and the pressure of the water starts to crush or squeeze the vessel the hull will literally start to get smaller, this could be easily verified by seing how much play you have in the string that was tight when the vessel was at surface preasure. Its not uncommon for the string to gain as much as an inch or two in the slag as the hull gets pushed tighter and tighter. If the string starts to exceed normal compression and become even looser, you would have a early warning that something is not right and the vessel is being pushed beyond its structural capabilities. One final suggestion would have been to split up the cylindrical preasure hull into 3 sections by inserting separation walls 5inch thick circular in shape at equal distances from each other. This in effect would have turned one long cylinder into 3 smaller ones greatly increasing the amount of compressive force the cylinder shape could withstand. When you are dealing with those types of pressures and forces you should never design the vessel to be good enough. It has to be made to withstand double the pressure you expect. The Trieste was created to wistand several times the force of the pressure it was going to encounter, and still the glass window cracked on the way down. If it was made just to the specs, it would have been crushed like a soda can. I believe this is where the flaw in the design doomed that Vessel. I haven't even addressed the horrible flawed design of bonding titanium rings to the outside of the carbon fiber body. Did no one see the disastrous flaw in that design. By doing that you now allowing the pressure to attack the carbon fiber vessel separately from the rings that are bonded on the outside. What happens if the pressure chamber compresses at a different rate than the Titanium ring. You have now created a gap which will tear the bonding agent, force the water in, and you can imagine the rest. The ring should have been designed in such a way where it fit or part of it fit inside the cylindrical body. Why did no one catch these potentially deadly flaws. Again I'm not an expert, and I'm not suggesting or implying that's what failed, but if I saw that design for my sub, I would have never dived even 10 feet in it, its still a flawed design. In the end this is a tragic situation, and I'm not blaming anyone, its not my place, the people ended up paying the ultimate price. I'm sure everyone had good intentions and no one purposely designs a faulty and dangerous vessel that they would have to entrust with their life. All im saying this should be a learning experience no matter how tragic. If I was going to design a sub, I would reach out to every design bureau that has ever constructed a deep diving submersible and seek their advice, ask for their opinions, and would pay them to assess and evaluate my vessel and let me know what concerns or flaws that need to be addressed, not to mention test it multiple times diving to the maximum depth the sub was designed for and evaluate its performance, before I let anyone board and dive that vessel. RIP to all that perished.

those rings could have been attached with Lepages paper glue they were in compression. The largest issue here is that carbon fiber is not a very good material to be used to withstand compression. great for tension but not for compression. They should have used a titanium based sphere similar to the Trieste design right down to using gasoline for ascent. And the way to prevent a view port failure is to use cameras instead. That's what Cameron did when he visited Challenger Deep.

So folks with personality disorders (such as Narcissistic Personality Disorder) are stuck in a holding pattern their whole adult life where they experience zero emotional growth and, unfortunately, end up hurting (or in some cases killing) folks who they manage to suck into their holding pattern (to use an aviation metaphor, since Stockton originally wanted to be a fighter pilot).

I'm a CNC machine operator so here my perspective. They have something calculated for 4000m. The Titanic is 3,800m deep. I think ISO (or NCEES or one of those) requires a 150% minimum buffer for engineered loads (meaning for diving 3,800m the sub would have to be engineered for 5,700m to be "save"). They're literally running at 95% at the Titanic. . . At that depth even temperature changes could have changed the water density enough to surpass the haul strength and crush the sub. Update : I'm right, this is exactly what happened. If it's any consolation they died almost instantly. The hull imploded, followed by their skulls, torsos, even their femurs because the center is filled with marrow. . . They basically turned into like a fine mist. Maybe their hands and feet were left but that probably quickly became fish food. The lesson here is to keep accountants out of the engineering room. . . . And also to hire professionals and not inexperienced people out of some sort of misplaced self-entitled wokeism. (That was very stupid.)

I worked briefly on a research vessel for an internship, and distinctly remember a conversation with various crew about this guy, Stockton Rush and Oceangate. They all said he was going to kill himself and others with his ideas -- this was quite a while ago when he was merely discussing the idea of taking people down to the Titanic, and hadn't actually built anything yet. I'm no expert myself, but seeing this now and the information coming out, it seems as though they were spot on. The fact that he once answered that his submersible was "too high tech" to warrant basic safety evaluations that most manned craft must go through, for example, was a big red flag -- and he said that about a year ago I believe. Having nice cameras or a custom-built cabin doesn't make your vessel particularly innovative, but especially when it comes to basic safety -- most of which was learned through decades of various catastrophes, as you pointed out here. There's a reason why captains and engineers are so stern about safety -- it can become a life or death matter within a split second. There are always risks involved, even just on a ship, but safety is not really something you want to dismiss entirely for the sake of innovation.

[@jhershy1381]

sad situation. But yea using ling time experienced people to build anything highly technical would be a best idea in my opinion.

[@MaschinenMusik]

What I really don't like about the design: - I assume the carbon fibre pressure hull was fabricated by winding monofilament around a cylindrical core (seen in the video), then it gets wrapped in a vacuum bag and then put in an autoclave. It's a good technique, but you still can have micro cracks and channels as a result that can be a starting point to fatigue cracking. - Combination of carbon fibre and titanium: You have a huge mismatch of the coefficient of thermal expansion of a factor 5 to 6 (cfk 50-60 x 10^-6/K vs 10 x 10^-6/K for Titanium) So when that thing cools down, the titanium will shrink much more than the carbon fibre hull putting allot of strain on the glued join. Thermal cycling -> fatigue cracking - There is a mismatch in elastic modulus of carbon fibre and titanium which will lead to a mismatch in elastic deformation when exposed to high pressure (only 1 atm in planes, 450 atm at Titanic level) --> again fatigue issues at the joints One can mitigate some of that by proper engineering, but combinations of fibre reinforced plastic and metal are tricky especially when cycled through pressure and temperature gradients.

[@razoraz]

Yes. I've spent hours reading this thread and there are many SMEs contributing here including CF, titanium, and sub building experts. This guy hired wildly unqualified engineers out of college and fired the expert who criticized the designs. I'm definitely checking out your musik!

[@horacewonghy]

And there’s are no reinforcement frame. Even the joints is ok, the CF tube would deformed easily after cycles, just like you said fatigue.

[@christianpatton9364]

Very good points. I remember when Grumman tried to upgrade the A-6 intruder with a composite wing. They had trouble with composite wing mating with the metal fuselage , gave them unexpected stress and fatigue problems.

[@kevinthomas5364]

Good points on the coefficient of expansion of various materials and accompanying fatigue failure - basic elements of engineering design for components subject to these conditions. The glue too becomes a big piece of this puzzle as it is part of the seal keeping the pressure out. Typically, dried glue tends to be more on the brittle scale with little plastic deformation upon failure. It appears that the joint design encapsulated the Titanium over the carbon fiber hull on both sides. This would put tremendous pressure upon decent on the Titanium joint squeezing the carbon it is glued too. The thermal and pressure stresses would be additive too as both would tend to squeeze the Titanium upon descent and move outward during ascents. This is a perfect storm forcumulative

I am not an engineer but the fact alone that this thing was designed to withstand the water pressure for up to 4000 meters and they were planning to dive to a depth of 3800 meters would make me feel unsafe.

And the latter is the actual real world performance - as exhibited in this case, it was not able to withstand it on repeated dives. So that's the problem.

As an engineer, here is what I see wrong at 4:50-4:59 : they are not wearing protective suits, it looks like open air factory, no particulate control of any kind, no masks, no hairnets. Once something is stuck to the adhesive it can provide a path for seawater to creep in, combined with vibrations and settling of the materials, steel and titanium being more prone to shrinkage with dropping temperatures at depth, there is a lot of mismatching of materials. I can see cracks forming due to internal stresses in tension, yes titanium is very strong so is carbon in tension but dust and rust on the adhesive can cause sheering and punctures... just too sloppy for experimental assembly of something that has to be perfectly smooth and free of debris.

Direct comms should've been left in, failure in deep waters of the passive comms used, shouldve been dealt with before guests were taken down. The sub should've been pushed to 4000 in test dives before guests were taken down to the Titanic's depth. Controls shouldve been hard wired and not off the shelf. Emergency O2 and mask should've been in place for the driver at least, so he could remain effwctive and save all the crew in an emergency. So many failures, and most of them easily avoided with patience, more testing, and use of input from more experienced personnel.

Man, exactly! That’s the real tragedy is the father and son. Why did the father bring his son?! Ohh man. 😞

They heard banging from what might be the sub, unfortunately it looks like the second scenario happened.

[@MockeryManor]

@@notjimmy6822 I hate to say it, but that’s just cope. The media is tempering the public’s expectations. The noises they heard are just ocean sounds. This submersible was not equipped with enough communication protocols. Sadly.

[@sheepyracing2774]

Yes that was a very risky idea for the father . I have a feeling it was instant death . Carbon fibre shrinks faster than titanium. Titanium will sheer off the carbon fibre like a bottle opening

[@notjimmy6822]

@@MockeryManor I dont see how thats cope, id rather hear that they died instantly in an implosion than be stuck in a tomb suffocating to death. The noises heard every 30 minutes from what could be the sub, which is evidence that they might have suffocated, the worst case scenario and the opposite of cope. But im not apart of the search team, and didnt hear the sounds. There will be an investigation to determine what caused their deaths, and whether or not the noises came from the sub.

Hearing the CEO's interview felt like being in one of those coach/motivational speaker's talks. I just couldn't take it seriously. Thank you for sharing those details and expert insights. What a tragic and seemingly avoidable loss of life.

Absolutely agree.

I've worked with some of the older military personnel. It's understood no two people are the same, but I've found these guys to be awesome to work with! I learned so much from working with them! I understand why military personnel are given priority for hiring. The logical problem solving, team working applications the ability to stay calm, because they've seen it all. This company would've only benefitted even if one was hired just to consult!

[@leecowell8165]

Military people are given priority because they do not question authority and do what they're told without a buncha lip. Tell you what though to become a submariner in the states you ain't stupid.

This isn’t a tragedy, this was entirely preventable and negligent. It’s criminal not a tragedy.

[@redmage777]

Why does being criminal preclude it from being a tragedy? Its all those things.

[@keenanmoore264]

They signed a waiver though. So any criminal charges would be negated, I think.

@@keenanmoore264 no waiver can save you from gross negligence. But the responsible is dead too.

@@keenanmoore264 most waviers like those "any injury is my fault" often fall through in court and don't actually make it the person who signed fault. its more of a deterant to sue than anything
