How Titan was Built, Lost and Found: An Analysis

[@iwannaratrod]

A couple of potentially key aspects that weren't mentioned in this video: A - The viewport was only rated for EDIT: 1300m. That's 1/3 of the depth to the Titanic. That was a flagrant, known danger point. Russian roulette on every dive with a negative safety margin. B - The engineering spec for the carbon fiber thickness was 7". They built it to 5". C - Preface: I used to work at Boeing on the 787 program, both post-cure and pre-cure. The 787 is mostly made of carbon fiber. Pre-cure was basically a low-level clean room. Not an open warehouse where people were at working areas with loafers and polo shirts. Every single large co-cured part underwent ultrasonic inspection and any defects fixed, and checked again for verification. The submersible did not get any testing for voids, inclusions, nor delamination after it was built. Any small one of those SIGNIFICANTLY weakens a co-cured composite structure by a significant amount. For them claiming to be primarily interested in scientific pursuits, they intentionally disregarded science, engineering, and safety standards, then claimed they got in the way of innovation. I'm fine with innovation, but when innovating, you put no lives or only put your life on the line...... not putting several uninformed lives on the line. In my opinion, the passenger's deaths are akin to homicide. Rules were intentionally disregarded, then lives knowingly put in significant danger. Edit: I'm in no way meaning to imply the video missed points intentionally. The stream of information about the disaster comes and goes, and I'm certain there was no ill intent, intentional misinformation, nor deliberate skipping of information.

Can’t speak for the weapons system aboard USS Colorado, but as a former submariner, there is a very big difference between the Titan being completely controlled by a game controller, and a game controller literally only controlling the periscope. Not to mention that the control surfaces (at least on board a 688i) have several redundancies and other places they can be controlled even if the ships control panel is damaged.

[@Pilot_405]

Great video! I gotta add, I was one of the CP-140 pilots, I flew the search over the 96th hour and was leaving the scene as the wreckage was discovered. As an ASW aircraft, acoustics is our bread and butter. We know the difference between biological, background noise, surface vessels, and subsurface sounds. The entire time the “banging” we heard was unlike anything we’ve heard before. It was to a cadence and we located it to a very small area of probability on the sea floor. It seemed to respond when we dropped Mk84 eSUS, or used active to Ping as a mode of communication. This is why we believed they were alive. As more ships arrived on scene, background noise drowned out the banging we heard, but we could still hear it on occasion and easily differentiate noises. The area we triangulated the banging to come from, in part using the echos through a passive sono grid and strategically positioning surface vessels to block certain echos, is where the wreckage was found. At the moment, we don’t know what the banging was, but could have been wreckage tumbling in the strong currents or small implosions from life support equipment as it settled. It’s a tragic ending and all assets on scene really gave it their all. Thanks for making a great video that lays it out nicely.

[@Lissbirds]

Could it have been possible that they didn't implode when they lost power but were instead still alive and banging on the hull for a few days? And then them banging on the hull caused it to crack and then implode? I'm just wondering how the banging fits into all this. I can't find a source, but other comments have said the emergency ballast was released, meaning they were on their way back up. So I'm wondering if they realized they were lost, tried to ascend, started banging, and the hull cracked as a result of the banging.

[@Pilot_405]

@@Lissbirds it’s very difficult to speculate, but the US Navy underwater hydrophone picking up the implosion sound around the same time the sub went quiet, sounds like it was all within rapid succession. The automated “ping” the sub had every 15 minutes was an isolated, separate system. So for that to go quiet at the same time as the implosion sound, doesn’t sound like there was any actual human banging. I will say, aircrew had that theory as well, of knocking which compromised the hull, but we don’t believe that any longer. We are still very puzzled by the banging though and hope for answers. As for the release of their emergency weights, we still have to wait for the exact sequence of events to be reported, but we did hear the mothership received a short text they were in an ascent briefly.

It's commendable you defended the OceanGate project, both its design, and its reason for existence - science. But I'd dispute that, as a scientist who has been professionally involved in studying and mapping the seabed, and I've made digital photogrammetric 3-D imagery. There isn't any science that this submerisible could do that couldn't be done as well, or better, by remote vehicles mapping the Titanic in detail. Which has already been done and which you pointed out. In fact the Titanic has now been mapped in incredible detail. Taking with them a man and his young son, both of whom had no scientific background, or reason to be there (apart from sightseeing) does not suggest any genuine science. Ok perhaps we could justify their presence by saying the company needed paying customers (with a high ticket price) to fund the project. But if doing genuine science, skip the need to make the vessel big enough for fee-paying passengers, and just build a smaller one (to take only genuine scientists), made from titanium as a sphere - as you showed in your excellent breakdown of Alvin. Finally, if this was all about science, why did Stockton Rush do the exact opposite of that? i.e. ignored the science that showed what materials you could and couldn't build with, ignored the necessary certification (which all genuine scientists would adhere to), and ignored what other experienced experts were telling him. It smacks at best of massive overconfidence in his own abilities, at worst of extreme arrogance.

EDIT JUNE 26: Hijacking this top comment to answer to claims that I am being an OceanGate "apologist". I'm sorry if my intention wasn't clear on this video; I am in no way affiliated with the organisation nor commenting on whether it was right or wrong to use this submersible. I only mentioned OceanGate's MISSION STATEMENT and pointing out that, at their core, OceanGate is an organisation with a scientific purpose with many operations not just related to Titanic dives. For Titanic specifically their science missions did the following; - Film Titanic in high definition from many angles to track deterioration and try to capture, on camera and in high definition, undersea organisms - Take water samples and use DNA analysis to identify organisms and try to match this with the footage taken from that specific dive Whether this is correct scientific method is beyond me; I just wanted to point out that OceanGate, the entire company, is not a sightseeing organisation as a whole based the above information. What is clear is that their business model then relied on public backers to keep these missions going and that those backers were given the opportunity to join the dives as assistants. Whether this is a pure "tourist" operation is open to interpretation by the viewer - I think it is a part of the business model but not the entire thing. I have not made any comment on whether the methodology or design doctrine was right or wrong - I have merely outlined what that design doctrine was. A CORRECTION: In referring to Titan’s wall thickness I mentioned 7” when I actually meant to say 5”, 127mm. Apologies for this misspeak! ANOTHER CORRECTION: Some of you have pointed out that my De Havilland Comet metaphor is based on outdated information.

The titanium caps were essentially glued with epoxy to the carbon fiber composite hull, and rather than the adhesives being applied in clean room conditions, they were done in an open air building by people in street clothes. Due to their design, the seams formed by the epoxy-joined composite and titanium segments would have been impossible to scan for damage even had Stockton Rush ever wanted to. Moreover, experts in carbon fiber such as advanced bicycle part engineers have fully known for years that carbon fiber composites degrade progressively with use under stress, can fail catastrophically at the worst possible moments, and that even with careful examination may only be known to be at risk only after they have already failed. Every one of the many cracks heard by passengers, as reported on earlier trips, was damage, accruing incrementally over time. Stockton Rush was not going to retire Titan any time soon, could never have detected its growing faults, and reacted bitterly to experts suggesting that he was putting lives in danger. So, Titan's eventual destruction was all but guaranteed. I don't expect any pieces of the composite hull or the bodies to ever be found; the immense pressure and energy of an implosion occurring at hundreds of atmospheres of pressure is hard to comprehend, but it would literally be over in milliseconds, superheating the air inside momentarily and turning the entire hull and its contents into small particles before the unfortunate occupants could even register the collapse. Stockton Rush made claims about NASA, Boeing, and the University of Washington being involved with the sub's engineering, which are now known to be greatly overstated. His victims, yes I say HIS victims, may have been considered crew members rather than tourists, but I struggle to see how a Pakistani billionaire father and his unwilling teenage son, whom he had to heavily coerce to overcome his initial refusal to join him, can be considered anything but unwitting clients, being given so many false assurances after paying hundreds of thousands of dollars.

Paragraphs, man, please use your return key! That having been said, I actually will take issue with the game controller. Not "because it's a game controller," but because: 1. The use of a _wireless_ controller introduces two additional, _unnecessary_ points-of-failure to a mission-critical component, that being power supply and wireless connectivity, when wired controllers work just fine and have neither problem; 2. Did they have a backup? The Navy uses the damn things because they're cheap, ergonomically tested far better than anything they ever could do, and you can send a sailor out with a rented van and a "company" card and return with a hundred of the things new-in-box in an hour and a half. So if the one they're using then breaks, they just toss it in the trash and pull out another one. Did Rush have a spare aboard? Probably not, knowing him.

Small correction about the comet, it didn't exploded because of the square windows, it didn't had square windows, they were rounded on the corners, the real reason was metal fatigue on the suboptimal aluminum alloy it was used, it wasn't good enough to withstand the pressure on the new altitudes it was supposed to go, also the rivets left microscopic cracks that eventually made the structure to be torn apart, and unlike modern aircraft, instead of tearing apart the skin and keep flying, it just couldn't hold on the structure and the plane broke apart almost instantly.

[@Papinak2]

Also, IIRC, they didn't test the entire hull, but only parts for cyclic fatigue and the number of tests was too small to properly assess the number of cycles the hull could withstand. Which is actually quite close to what happened with Titan.

Thank you, I came to the comments to add the same correction. The square windows, had they actually been squares, would of course have acted exactly as Mike described.

[@robertfolkner9253]

On top of the airframe, directly over the flight engineer’s station, were two small, square windows. These were used in conjunction with the radio equipment, guaranteeing good signals. They were supposed to be glued-in, but instead they were punch riveted, forming tiny cracks. After so many flights these cracks expanded and grew down the hull to the windows. It was at this point that failure occurred. Also, the aluminum used in the airframe was the thickness of two pennies.

[@emty9668]

They took a Comet Aircraft hull, placed it in a tank of water then filled the hull with water to what the pressurised hull would be. They then cycled this to represent take offs and landings. They also recovered a lot of one of the aircraft from the Mediterranean seabed and rebuilt it around a frame in a hanger. The hull that was being pressurised failed unexpectedly and suddenly. A crack emanated from the corner of a window. Airframe fatigue was a new science at the time and a lot of this was unknown. When the Comet 2 was put into operation the windows were small and rounded. The RAF Nimrod was a variation of this aircraft and flew successfully until 2011 and then retired. There were a couple of airframe losses, one over Afghanistan unrelated to the original problem.

[@onemoremisfit]

As a complete layman it seems to me the acoustic warning system that drops the weights if the pressure vessel makes telltale noises of impending breakup was worthless because once you hear those noises you have seconds to react, and the ship can't change its depth significantly in seconds. It took hours for it to free fall to the target depth of ~12000 feet. Lets say the cracking noises happened at 10000 feet, they took action and dropped the weights, but then the momentum of the ship still continued downward for a second, then slowed to a stop, then reversed to begin accelerating upward, and all that action took say 5 to 10 seconds before the ship attained any significant upward speed. It may have managed to reduce its depth by a couple hundred feet before BOOM, it imploded at say 9800 feet, which was not enough pressure reduction in time to save them. Like the Titanic was unable to make enough course correction in the time it had to react to the sighting of the iceberg.

[@isleofthanet]

If Titanic has carried on instead of turning it probably wouldnt have been so catastrophic.

[@onemoremisfit]

@@isleofthanet Yes, I have read that assessment by experts decades ago, that if Titanic had rammed the iceberg head on then it would not have breached as many watertight compartments and would have not sunk, or at least would have stayed afloat a lot longer and would have still been afloat when help arrived. The trade off would have been that potentially hundreds of people in the front of the ship would have died in the impact of such a collision, and the officer commanding the ship would have to answer for that. There was no way the commanding officer with seconds to react would order the ship to ram the iceberg, sacrificing the lives of some to save the rest of those on the ship. There just was no realistic opportunity to consider options like that in the seconds of time allowed to react. There was also no time to consider ship engineering outcomes of say 3 compartments breached vs 5 compartments breached, etc. It was all or nothing, he had to try to steer around the iceberg.

[@gailmcn]

@stephernoodle. so far all the interviewed passengers have verified that Rush made it clear to them that this was an experimental vessel. What he did was make that a 'reason' for why they could ignore that it was an uncertified, unclassified vessel (can't be certified yet, too innovative). He also used it as an emotional hook for his targets, which were of two main types: Prospective paying passengers who were attracted to unusual and risky adventures. Also, prospective discount/sponsored passengers who had huge media/KZbin followings, who could be depended on to provide free publicity to millions for Oceangate Titan. He did this by connecting 'experimental' with "ahead of the pack", nobody else is doing this, "you'll actually be Crew participating in groundbreaking science", etc. A Supersalesman is what he was, who was basically making a bug appear to be a feature.

[@dogood1785]

He may have informed them that the vessel was experimental, but I highly doubt that he disclosed "all" the problems that the Titan had to "paying/potential" customers ("mission specialists"), and just how cheap and experimental the vehicle really was. Did they fully know and understand all the issues with that submersible, such as thrusters and computer/control systems problems they were having just days prior to Mission V, which he stated, was like "life support"? Were all the problems fully resolved, considering they had to sign waivers? It was his responsibility to fully disclose everything, as they had to sign waivers -- speaking in terms of the paying customers, not the guest, because I believe, PH fully knew what was going on. Honestly, Rush was not a "supersalesman," but an extremely dangerous and delusional man, who double talked (a liar/deceiver). He went on record saying, "safety is pure waste," but apparently, he made those people feel the vessel was safe to some degree. According to a news source, the wife of the Pakistani billionaire reported, SR and his wife flew to London and met with them some months prior to Mission V, where he discussed the mission and reassured them the Titan was safe.

Mike, a quick note on how the titanium rings were attached: they were bonded using an epoxy (in layman's terms--they were glued together). It is concerning that this was done in a warehouse (as seen in your video). Any dust or particulates could have gotten in and created a potential source of weakness in the epoxy. In addition to the many other shortcomings of this design, the building practices also fell short. Given the tolerances involved, this step should have been performed in a controlled clean room.

​@@exasperatedWhen I initially viewed the video of the sub's end cap to carbon fibre tube joining process, I saw the handwriting on the wall. Critical processes were being done under contaminated conditions, epoxy was applied using a paint brush with no control of the amount or precise location, the physical joining of the elements was done using no stable alignment mechanism (a k.a. the "we got lucky this time" process control system) that leads to momentary canting of the end caps as they are inserted into the tube (causing irregular distribution of the epoxy in the interface area.) These potentially seriously degraded bonds are then subjected in use to the effect of the greatly differing coefficients of thermal expansion between the carbon fibre tube and the titanium end caps when the sub cools at depth in frigid ocean water. All of the preceding could have easily contributed to a separation of the thermally shrunken end caps' OD's from the tube ID's, creating stresses at depth that the carbon fibre tube ends could not withstand. Even the smallest crack or delamination in the tube would have led to the total failure of the tube at depth. The science of what I wrote is sound. It may not have been the cause of the catastrophic failure; but in my gut, I have to believe it almost certainly was.

The material choice of carbon fibre over a proven metal pressure vessel baffles me. Everything I'm learning about this disaster just makes me wonder how Titan was ever meant to reach the depths of Titanic without risking failure

[@ShadowDragon8685]

Probably a combination of hubris and "oh, engineers _always_ build in a huge margin of unnecessary safety so they don't get sued." The use of a carbon-fiber pressure vessel may not _inherently_ be a fatal objection, but at the bare minimum it needed to be _thicker._ Five inches sounds like a lot, and if you're making an aeroplane to fly up high in the sky, or a racing car or whip around the track at Le Mans, it's insane. At 3,800m of North Atlantic, it's insanely thin.

[@irieite9666]

Because with Titanium it would only fit 1 or 2 passengers. They wanted more. Its a story of a company in red and continuing to lose money cutting corners to try and squeeze a profit.

[@methylene5]

The Titan cost around $370,000. For a metal hull that can only carry two people, will set you back $37 million. 100 times the cost. The carbon fibre hull should have been thicker, and even at 5" thickness it had completed 13 prior successful trips to the Titanic. It's a no brainer why they were tempted to use carbon fibre.

[@michaelsteffensen6844]

A lot of the talk around OceanGate and Stockton Rush is pretty damning. His refusal to get third party certification on an experimental submersible AND take tourist on board is simply inexcusable. Stockton Rush has said in interviews he believes certifications would slow down progress and stifle innovation. The real kicker, though, is he claimed all these certifications were overkill because almost all issues experienced in deep sea submersible vehicles were human errors during operation, a fact which only serves to prove how essential and effective these testing methods are. He even refused an ultrasonic hull integrity test to find any imperceptible stress damage to the carbon composite material, which was the likely the cause of this tragedy.

[@Karl-mw5li]

Agreed - yet instead he went with a more expensive, entirely pointless 'safety' system. "He even refused an ultrasonic hull integrity test to find any imperceptible stress damage to the carbon composite material, which was the likely the cause of this tragedy." - even more bafflingly, he installed a sonic/strain-gauge based hull monitoring system to the submersible... which would give essentially zero warning and would only tell you once the damage has already happened. It's like fitting a smoke alarm that can only work once your entire house is on fire. Having it tested like you say would have potentially highlighted issues ahead of time.

[@ShadowDragon8685]

Not necessarily. The hull was quite simply too _thin_ for the job. A vehicle can pass every imaginable certification and then catastrophically fail when put to a purpose its design is inadequate for. Even the legendarily indestructible Toyota Hilux pickup truck, after all, is only used as a vehicle in warfare by the desperate.

[@methylene5]

Everyone keeps saying the same thing, but it would never be certified, even if it were 100% safe because the technology is new and there are unknowns. Simple as.

It's crazy to me that after 111 years, the Titanic is still claiming lives, and for largely similar reasons. The hubris and ignorance of safety measures of both the White Star line and Oceangate staff is what led to this tragedy

[@AHHHHHHHH21]

The staff just did what they were told, the ones who spoke out were fired

[@ShadowDragon8685]

White Star didn't have a willfully negligent approach to safety though. They implemented safety measures that were higher than to the required regulatory standard at the time. In the grand scheme of things insufficient, of course - the gold standard of oceangoing safety being William Francis Gibbs, whose vessel Malolo in fact survived the very same type of collision that doomed _Empress of Ireland_ and _Andrea Doria,_ and which - along with _United States_ - would have easily survived the impact that felled _Titanic._ But they were not _negligent._ Stockton Rush, on the other hand, was _openly, and vocally opposed,_ to any kind of safety requirements being imposed on him. That's why the _Titan_ was not only uncertified, it had a waiver that mentioned 'death' like ten times, and tried to bypass liability by classifying paying passengers as "mission specialists." OceanGate, unlike White Star, was willfully negligent, and they are probably about to be sued out of existence.

11:25 In that video of the *actual* carbon fiber being wound, that activity probably should have taken place within a clean room. Because there were people within several inches of the carbon fiber being wound, particles of dust and other debris may have contaminated the carbon mesh, creating points of weakness. Over several dives, these points of weakness or delamination may have grown. Also, microscopic air bubbles in the carbon fabric could have produced a similar effect.

Good video, with a lot of useful information. I want to comment on Carbon Fiber as a material. Carbon Fiber is one of the strongest materials known. It's commonly used in aviation for the pressure hulls and fairings. However, it is a FIBER... a THREAD... When you pull on it, it's incredibly strong. But when you push on it... Well, take a length of dental floss and pull on it. Then push the two ends together. That gives you an idea for how Carbon Fiber works. Make a bottle of carbon fiber and fill it with something and it can withstand massive amounts of internal pressure. However, that same bottle can be crushed with a fraction of that from outside. Using carbon fiber to make a submarine was a very strange decision.

[@globalcitizenn]

Stockton was an aerospace engineer who forte was making aircraft where carbon fibre is used for pressure hulls as you said. Maybe he just didn’t have enough deep ocean engineering knowledge and didn’t listen to the experts

[@pradnyachoukekar]

thank you for dumbing it down

[@nevem5010]

I do appreciate you trying to be nice, but there's a fine line between kindness and apologism, and imo you crossed it here. Rush's lack of respect for basic safety is on public record, in his own words; it's both undeniable and inexcusable. The people who've died as a result of his behaviour deserve better.

[@lizziewalker7844]

Maybe he will make another video about that when more time has passed. There is no excuse for Stockton Rush though, especially now we know a 19 year old boy did not want to go and is now lost.

[@dannyfowler7055]

Interesting explanation of the methods used. I spent 23 years in the US Navy, many of those with the ASW Community and spent many hours flying in the Great P-3 Orion. The P-3C can find you underwater using a number of methods, not the least of which are sonobouy’s and the MAD Boom (Magnetic Anomaly Detection). I was friends with many of the Technicians who operated this equipment, and believe me they are a talented group. Just ask any Soviet Navy Submarine Skipper who was chased by them. 😊Enjoyed your presentation, thanks!

[@maranscandy9350]

It was said elsewhere that the submersible’s carbon fiber hull was wound in a warehouse type environment that wasn’t dust-free and was not temperature controlled.

[@Spamhard]

You can see that in the footage on this video. it's got loads of people wandering around with cameras and stuff just watching as it's being wound. They also glued it in the same environment, and placed it together with a winch and a few people eye balling it as it was lowered down.

[@Nelay_Lee]

It was cured at 137° C for 7 days and it was wound properly . Thank you for your.. I heard this from the internet false statements

Why don’t you mention that apparently the viewing port hole was only rated down to 1300m -WAY LESS than the required 4000m depths it was traveling to. You even go so far as to refute that the port hole would be viewed as a weak point. Maybe not usually, but THIS ONE definitely was

I greatly admire your restraint and choice to wait before posting a video of the events surrounding the Titan submersible. I have thoroughly enjoyed this channel and the intelligence and dignity brought to these subjects. When the submersible was first announced as being lost last Sunday, the authority I wanted to hear from on this subject was this channel, but I also knew that speculation was not going to be helpful, so thank you so much for the brave choice to wait before significant facts were in, and in sharing the information about the technical details of both the submersible and the technology used in the search.

[@TybJim]

Somebody must have paid this channel money to defend Oceangate. I watched the original Ballard expedition documentary as a kid on VHS. Back then as a child I understood why there was so much pressure and why the sub such a small and round crew compartment. When I saw Stockton Rush climb into his 'sub' during a news interview and my blood ran cold! It is widely publicised that many people warned Oceangate about the dangers of their Titan sub, and it was ignored. This isn't like Titanic's metal quality, where they didn't know any better how it would react in cold, they did know better when it came to the Titan sub!

[@AvonleaMontague]

From what I've been reading, the coast guard did not hear the implosion in real-time but instead were given information that the sub went missing, may have imploded, and were directed to listen through their recordings and see if there was anything.

[@nukamolly]

i think it was the navy that was peeping their communications, noticed the comms went down, and reported to the coast guard. that’s my understanding of it at least.

[@artemisameretsu6905]

Regardless, can you imagine listening to the recording and just hearing the death of five people instantaneously 😰

[@steakthedoggaming5333]

I will note something on the SOUSUS Net track from the Titan Implosion, the big reason it was kept in house until confirmation that the vessel was lost is that they weren't sure the sound actually was the Titan imploding, as identifying sounds from under water can be quite difficult, as noted, so the thought was that it could of been some other underwater activity that happened to sound like an implosion. With hindsight it's easy to see it as a potential wrong choice, but at that point it wasn't even public that the vessel had been lost.

[@StLProgressive]

I’ve been waiting for your take on this tragedy. I can’t help but feel the similarities between Rush knowingly cutting corners and ignoring safety regulations and Captain Smith rushing full steam ahead, ignoring the ice warnings. Both men thought they knew better. Both were wrong. James Cameron was right, now we have 2 wrecks for the same reason. My heart breaks for the loss of those souls, especially the 19 year old kid. I’m glad it was quick, and they weren’t stranded waiting for the O2 to run out. May they Rest In Peace.

[@martymcpeak4748]

he was quoted as saying he broke a lot of rules to make the submersible happen.

[@callummclachlan4771]

Yeah. As much as the loss of Paul-Henri Nargeolet hurts. He had a long and successful life. Same can't be said for the 19 year old who still had his whole life ahead of him. Certifications and standards exist to stop (or at least reduce the chance of) this happening. Unfortunately the history of the company shows this was a tragedy in the making.

I don’t understand why people keep focusing on the “off the shelf” parts. There’s nothing wrong with that and in most cases it makes total sense to use off the shelf when appropriate or beneficial. They weren’t cutting corners by using off the shelf. There’s no need to design and engineer a super complicated mouse trap when the tried and tested basic mouse trap works perfectly. As mentioned in this very video the US Navy now uses off the shelf game controllers to control their new submarines. Game controllers are used for a lot of military applications.
