I've watched about 30 videos on this subject. This is the most concise, informative of them all. Excellent presentation.

You are right about the issues with carbon fiber. My father worked in aerospace, and most of what he designed is still classified so I've heard about very little of it aside from a few satellites as they were declassified and parts he worked on for the shuttle. He mentioned the issue with carbon fiber after the roof of several airplanes tore free in Hawaii. Carbon fiber cracks from the inside out and is incredibly difficult to examine unless you have the proper equipment Metal tends to show signs of surface deterioration, so one can often determine that there is an issue. When power to weight is crucial (military aircraft, etc.) the risk is worthwhile, but otherwise carbon fiber is taking a huge risk. This is especially true for a craft that will get compressed to this extent. Each pressure cycle could be doing serious damage without the company being aware.

@standbytogo123

11 ай бұрын

It was mentioned in another video, that the construction was a carbon fibre composite, ie a sandwich construction with another material being the meat between the carbon fibre layup on either side. This type of construction is stronger than say pure carbon fibre panels. However the strength relies on the bond between the sandwiched material and the carbon fibre being one hundred percent. Any voids in the bond would weaken the construction. The only way of knowing that it was one hundred percent would be to carry out NDT (None destructive testing). As has been mentioned this was never done following construction or after any dives.

I don't doubt the discussion came up prompted by the Hawaiian incident, but that was aluminum. That said, it's a great illustration of how a rigorous testing & cert regime can help solve problems & prevent failures. Metal fatigue is better understood than carbon fiber fatigue & so they were able to take the findings from that incident & quickly pinpoint areas to look at on other 737s - my recollection is that a number of planes were found to have similar issues & then either repaired or taken out of service.

The Hawaiian passenger jet being mentioned was hundreds of cycles over the required limit; in other words, it was an old aircraft that was supposed to be decommissioned, but was extended I suppose for other reasons.

Old retired Engineer here, mostly worked in Aerospace. I think you covered this very well. I would like to touch on 2 points if I may. First off is redundancy. When we build experimental aircraft, we try to figure in back up systems. You touched on this with the inability to navigate, locate, and exit the craft. Unlike most airliners flying today that have a whole backup system for comm, hydraulics, navigation, even the artificial horizon, this craft had little to no backup systems, from what I have seen. Second is the fact that Engineers get constantly surprised even on the simple things. I recall that the Galaxy C-5 Starlifter was found to have the main supports turned to powder on the inside, showing no signs of stress on the outside. The only way to determinate this was through a destructive test. While Carbon Fiber is a remarkable material, it is not a "one size fits all" material. The people probably never knew what hit them. From what I was told, the implosion took 2 nanoseconds, and it takes 4 nanoseconds for your brain to register pain from your nerves. Thank you your thought out presentation, I think you covered it very well. Also for letting me put my 2 cents in. Smiles.

A slight correction, I think you meant to say milliseconds and not nanoseconds. The implosion of the sub (given the dimensions of 670cm x 280cm x 250cm), and assuming they were at 13,000 feet under water, the estimated implosion time would take about ~4.50 milliseconds. Depending on the type of nerves, the human body would feel pain after about ~30 milliseconds. Given this information, they should have not felt any pain and died almost instantly.

I've spent 17 years in the NDT industry and find it amazing that a vessel with human lives aboard could be sent to such incredible depths without undergoing a process like NDT. Whether or not it was in aid of protecting the lives of anyone aboard, it would have given Stockton Rush peace of mind in the security of his asset let alone abating some of his risk. There are methods such as acoustic emissions testing or Ultrasonic flaw detection that would have allowed monitoring of the hulls integrity before and after missions, and detection of fatigue stress cracking or potential delamination in the hulls materials that could have given hima clear indicator of the vessels integrity. Not only would they have saved lives (including the founder's), but they would have protected his asset and at a fraction of the cost of this tragic outcome.

Since you indicated that you were in the NDT industry; wouldn't it be prudent to perform some destructive testing to determine the failure point (this would be after all other testing and fixes implemented to resolve the issues uncovered)? Take notes from that and institute fixes? When I was in middle school, I built a bridge using popsicle sticks and Elmers glue. The initial design of the bridge was to run a bunch of matchbox or hotwheels cars through it. The destructive test that I subjected it to was to put a weight on it. My teacher had a weight which we could tighten by turning a knob. The thing started to crack at about 70lbs (you could hear it, but not see it). As I kept turning it the cracking got louder and louder, then started to show, eventually by almost 80lbs, it collapsed. Note I wasn't going to build a new bridge. I just wanted to see how good (or bad) the bridge would be. I would have been happy if it supported 10-20lbs. It was made out of regular popsicle sticks and children's glue.

@@crazybrainos good question and yes, destructive testing is normally a part of the pre build design like tensile testing (destroying an item to determine its failure point then giving a strength rating based on that), as is NDT (Radiography and Ultrasonic testing of welds and materials to examine for defects). However where I work in NDT it is used as a preventative maintenance and asset care tool for assets already in service, ie looking for and monitoring corrosion in gas pipes, detection and monitoring of cracks due to cyclic conditions (pressure, temperature or load bearing cycles) as well as due to vibration and age fatigue (cracking due to vibration or time). There are several industries in this area utilised by engineers as their 'eyes and ears on the ground' to certify a product to ensure its reliability and safety. All the industries (destructive testing, non-destructive testing, condition monitoring, in service inspection) work hand in hand at all stages of a products life cycle right through from initial design, to service lifetime to decommissioning.

I should probably elate... Usually, on a solid material, ultrasonic sound waves would be passed through the material to search for defects such as delamination, cracking, pores or loss of material. This is done by bouncing the ultrasonic sound waves off the back wall of the material. Unfortunately in laminated materials, built by bonding several layers together with a glue, the sound will only travel through one medium (ie the glue) so would be interrupted by the layers of carbon fibre which would disrupt the sound path. However other methods could be used in conjunction for testing laminates such as acoustic emission testing (placing microphones on the surface then forcing the material to listen for disbonding or cracking) and radiographic testing which could be used for volumetric defects like air bubbles or possible cracking in the material, but not good for finding planar defects like debonding between the laminated sections. Using several of these methods together, along with destructive testing and cyclic testing would paint a pretty clear picture, however would have been expensive as a customised one of inspection plan would have to have been created specifically for this submarine. However, despite the cost, it would have not just saved 5 lives but also the company's fate.

The more I hear, the more shocked I am that it survived as many dives as it did before this happened. As the phrase goes, "Regulations are written in blood." So many corners cut, so many lessons from the past ignored, and so much ego on Rush. Sadly, this ended in a predictable fashion and it cost the lives of five people. At least I take some solace in knowing that they all died instantly and without pain.

Yes. However, they almost certainly must have known that they were in mortal danger prior to their instantaneous death by implosion. According to James Cameron, pressure sensors would have gone off before the event. He also said that members of the diving community related that the Titan had dropped its weights in order to begin to ascend. That would certainly have been absolutely terrifying especially for the kid whose aunt said he did not want to go down there because he was afraid, but he went because his father wanted him to go with him on Father's Day.

When the hull actually imploded, none of the passengers knew a thing. Death was faster than their brains could register what was happening.

He over engineered his challenger craft and made sure it was safe and he said himself he never once worried about his hull integrity while making the titanic dives or even the Mariana Trench dive. You worry about things not working like robotic arms and lights or ballast removal systems and coms but you never worry about your hull because you over engineered it to withstand much deeper depths.

I'm not sure how this could or would be regulated, though common sense says that it should have been. Perhaps going forward it will be, but James Cameron interjecting would, sadly, likely not have prevented this tragedy. Hard to say. Shoulda, woulda, coulda. Maybe he didn't feel it was right to engage the authorities against a private citizen exercising his own free will? Having said that, creating the illusion that the craft was safe, accepting sizeable fees to take civilians on these dives could arguably be considered criminal. There were certainly concerted efforts to present the operation as legitimate and scientifically sound & safe, which is why billionaires would entrust their lives (and that of their son) to this effort. Once you begin accepting money from private citizens, the stakes have been raised. Though, what's the difference between this and Bezos going into space, taking an 18 year old paying customer aboard Blue Origin? What if that had gone wrong? Not sure there are good answers, but one thing is for certain, this was a horrific end to what began as a neat idea, and it's too bad the poor folks who perished put their trust in a man who's arrogance, delusion or ambition was more important than their safety.

I work in carbon fiber manufacturing. I am not an enginerd, I'm just the guy that takes the plan and lays the carbon up, and actually makes the parts... As soon as I found out how this was built I was shocked. The coefficient of thermal expansion and the compressibility of the Carbon tube and the TI end caps was a recipe for disaster under these kinds of pressures. It's just bad engineering. If we get to look I suspect we will see that the failure happened at the joint where the carbon and TI met up with each other. The sub was obviously robust enough to survive a few dives but really they should have been taking X-rays of the vessel for failures after every dive.

Honestly don't think anyone would have stopped to check the submersible in any case. The headline reason would have been " tourists go radio silent for x hours in exotic submersible"...and would have resulted in investigation of communication equipment. Unfortunately, in this case, not taking extreme caution when engineering the vessel, and lax regulatory oversight. But, that would have been expected if the company over promised capabilities. So, do the mega containerships that sit heavily in the water require rigorous tests of their hull integrity over x operational hours per design engineering? Is that an oversight or unwarranted concern?

The fundamental design flaw for this vessel is that the designers forgot that "You can't push a rope." All fiber composites have their greatest strength in pure tension. Such materials are ideal for pressure tanks, which have a hoop stress of pure tension. The Titan, however, was not a pressure tank, it was a type of vacuum chamber, where the hoop stress is pure compression, and depended on the integrity of the resin matrix for its strength. Repeated cyclic compression along the fiber axis will cause microscopic separations to accumulate between the fibers and the matrix, eventually leading to microscopic fiber buckling. Fiber composites are highly anisotropic materials, and the designers did not take this property adequately into account. Failure in tension is radically different from failure in compression for these materials. Metals are almost completely isotropic in their mechanical properties and do not have this problem. Metals also have some ductility and will get stronger by work hardening before they ultimately fail. Fiber composites behave more like brittle materials and their fatigue life is not well characterized, especially under cyclic axial compression conditions. They fail suddenly and without warning, even when their application loads them mostly in tension. When the Titan hull suddenly failed, it was crushed by an immensely powerful water hammer powered by enormous momentum which probably turned most of the fiber composite mass into fine dust which will never be found. The underwater implosion of the Titan could conceptually be compared to the implosion of a plutonium nuclear bomb pit like the Trinity 'gadget' (without a subsequent nuclear fission reaction).

SPOT ON! The day after they went missing, a video showed how this craft was built. When I saw that and knowing that communication had just stopped abruptly close to the bottom, I commented that I was sure the craft had failed. That was at least a couple of days before they found the debris. I was absolutely shocked when I saw how they made that thing. I am a physicist and an aerospace engineer, and although not a materials engineer per say, I have a very good appreciation of such things. Carbon fiber has tremendous tensile strength, which is why we make rocket boosters out of it, since the pressure is on the inside, producing tensile hoop, stress, that the carbon fiber is very good at handling. But in compression, carbon fiber is nothing more than a wet noodle! It is insane to have made such a submersible from this material. Steel, titanium, and glass All have tremendous compression strength, which is why they are used on every other submersible. Heck, he might’ve been better off, making the darn thing out of concrete, since concrete has high compression strength as well. Just to be clear, I am jesting when I suggest making it out of concrete (just so some fool doesn’t take off with that ridiculous idea). But almost seriously, one could at least argue that concrete would’ve been a better material than carbon fiber for this application. This just shows how a combination of ignorance, and not understanding true physics and mother nature, combined with hubris, is always a prescription for disaster.

The tragedy we spent the most time on was the Challenger, and it sounds eerily familiar to what happened with the Titan: Safety procedures weren’t thoroughly carried out, material deterioration wasn’t taken as seriously as it needed to be, focus was placed more on publicity than caution, and those who raised concerns were silenced and punished. It’s heartbreaking to see disasters like this repeat themselves throughout history. People are incredibly curious, and it is a worthy endeavor to explore, but we need to remember why we do it in the first place. It’s important that we understand the need for caution, listen to each other when improvements can be made, and learn when it’s best to hold back and learn a bit more before someone gets hurt.

That's really interesting, thank you. History is there to be learnt from and let's hope this can be learnt from so we don't repeat the same mistakes again. I should imagine there will be some interesting discussions in the coming weeks, months and years in the engineering academic institutions around the world!

This feels like the Space Shuttle but where all the risk factor dials were turned up to 11. The Shuttle feels like one of those engineering case studies where fixing just one of the faults could have prevented the catastrophe. If it wasn't so cold, if the pressure to launch wasn't so great, if the materials science was better understood, etc. OceanGate feels like any of the systemic failures could have caused the catastrophe. Using an Xbox controller? Coulda. Losing comms for 4 hours at a time? Coulda. Hatch openable only from the outside? Coulda. Carbon fiber? Coulda. So many opportunities for catastrophic failure, loss of crew and vehicle. You would have to fix all of them to make it a safe vehicle.

Teachable moment: don't use composite materials when designing a vessel that is going to be subjected to insane pressure. Also, don't use half assed parts for a vessel that is going to be subjected to insane pressure. Look at the cost and the time and engineering and the materials and testing that went into the submersibles that Ballard and James Cameron used, as well as those used by the Navy and legitimate deep sea rescue companies. They all have one thing in common-they all came back to the surface in one piece.

According to the movie which James Cameron said his research team did a pretty good job to provide as accurate information as possible. One of the wealthy tycoons wanted the captain to lit the last set of boilers for the engine despite they have not been 'run in'so the ship could reach New York a day ahead and make news headlines, so they were traveling too fast for the rudder to make quick turns to evade the iceberg. Another point was the Titanic didn't carry enough lifeboats because the boats created too much clutter on the deck and wasn't deemed aesthetically pleasing.

This was very insightful and extraordinarily well-done. My father was an engineer. A few things he told me stuck with me, one of which was single materials are much stronger and more reliable than composites. He worked for an aviation corporation and resigned, after they refused to listen to his caution about a design flaw. Two test pilots were killed in the inaugural run. Even though he had tried to prevent the accident to the point of resigning, it always haunted him that two good men were killed for no good reason other than corporate greed.

@MacNerfer

I don't agree that single materials are stronger. The opposite is often true, for instance car windshields are made of several layers, plywood is made of several layers, and that is done specifically for increased strength. It all depends on how it is assembled and the how the materials relate to each other.

Just like composite armour plating was NEVER as resistive as homogenous armour plate. Ply wood sheets as a function of area and depth are not even close to a single equivalent fblock of wood. Its just easier and cheaper to make larger areas of wood from ply. Ply uses cheap woods glued together. See above composite armour.

James Cameron had a pretty good point about the carbon-fiber hull, pointing out that carbon fiber's strength applies when it is under tension, but deep ocean diving puts it instead under compression. This probably caused more damage and degradation to the hull than expected. He even posited the pressures at extreme depths could cause water to infiltrate the mesh and start delaminating it.

@@iloveaviation-burgerclub-a8145 Yeah I'm of the mind that carbon fiber is an incredible material but it isn't a Solution To Everything, it has to be used _correctly._ Would be excellent on aircraft and spacecraft, because containing pressure inside a vessel puts the fibers under tension, where they're strongest. Containing a low-pressure environment against a high pressure exterior is the exact opposite of what carbon fiber is good at.
