It's supposed to float to the top on its own in an emergency, so I thinking some sort of explosive decompression and they're all dead. I have thought it would have some sort of emergency sonar location beacon also:

For only $250k you can go visit the historic site of the Titanic. You can also join the historic wreckage for the price of COST INCLUDED.

Yup, not gonna end well. They have 7 different ways to get to the surface, some are automatic if the power cuts out and other safety measures. That none of them deployed, they're done for:

Oh sure, some rich folk die while doing something crazy dangerous without any benefit and it's global news coverage, but Uncle Jed dies doing something equally dangerous that cost his entire bonus, and where's the news coverage for that?

Not for nothing, I won't be surprised to see this with 'space tourism,' either. There are reasons those environments--12,000 feet deep or 130 miles high--have had so few visitors.

They would go down in a Bathosphere for long stretches. He said it was great money but scarey as hell, he told me about a hammerhead that kept circling him one day, he said it look as big as a Bus from his point of view.

Both we will see more of no doubt. I'd be happy as chit to be a space tourist if that kinda $ was no big deal to me, no interest in being in a tiny sub with one tiny window to see boring ship at 13k ft down. No idea why the fascination with that ship.

More like rapid implosive compression….

That they don’t even have a ping from it is weird…. You’d think that it would have some kind of dead man or other kind of self deploying signaling system…

How far could the thing get? Wouldn’t you follow it on active sonar?

Someone, somewhere must have heard something, if it imploded.
Will anyone admit to listening, or having that technology?

I recall the Scorpion was heard on a passive array at the time it went missing.

I could think of a hell of a lot better ways to blow 250k. You could take a killer cruise on the QM 2 or Seabourne with that. Or, any number of better things than a dodgy ride in a steel coffin down to 12000 feet to look at a bigger steel coffin.

Yeah, with lots of things you need to accept that you might not come back, but seems not everyone gets the memo. There are lots of things I'd like to do, but good reasons I've never tried them. I've weighed the "wish I could do that" benefit against the "this could easily happen" outcome and concluded that I get enough excitement paying my mortgage every month.

I'm thankfully past the point where I feel compelled to prove things to myself or others and I have too many responsibilities to engage in antics for the entertainment of others.

Among those paid passengers was British businessman Hamish Harding, according to a statement from Action Aviation, a company where Harding works as chairman.

Harding holds three Guinness World Records, including the longest duration (4 hours, 15 minutes) at a full ocean depth (2.88 miles) by a crewed vessel. He has also trekked to the South Pole, circumnavigated the Earth in less than 48 hours and visited space in Blue Origin's New Shepard rocket.

A fourth person on board is Paul-Henri Nargeolet, a French expert on the Titanic, his agent has confirmed to several outlets, including The New York Times. Nargeolet serves as director for RMS Titanic Inc., the U.S. company that owns the salvage rights to the Titanic site. The Times reports that Nargeolet has completed over 35 dives to the wreckage, including a previous Titan expedition.

Aparently you "Float" to the bottom without power, then power up to position the Sub toward the Titanic. They never powered up, if they have a loss of power, they are already dead.
You would no longer be able to scrub the CO2 out of the system.

Banging sounds picked up on sonar

“Crews searching for the Titan submersible heard banging sounds every 30 minutes Tuesday, according to an internal government memo update on the search.

Four hours later, after additional sonar devices were deployed, banging was still heard, the memo said. It was unclear when the banging was heard Tuesday or for how long, based on the memo.”

Fox interviewed a guy who had been on the sub and seemed to know a lot about it. Said that in the case of losing power there were backups for scrubbing C02 and multiple methods for getting back to the surface. He leaned toward a loss of pressure (catastrophic) or the sub getting snagged on something preventing it from surfacing.

99% of the time when such things happen, it's always traced back to human failures of one sort or another. Space Shuttle, most plane crashes, etc, etc. There's always a history that leaves one to conclude it was just a matter of time. Post (avoidable) tragedy, changes get made, but people always have to die first for anyone to wake the F up.

That's significant, the PSI at 1,300m is about 1,900; 4,000 meters is about 5,800 PSI. That ain't a small difference.

If the above is correct, there's no hope for those people and that sub. It probably looks like shredded soda can right now and the human remains ... well .. I hate to imagine.

The question is why did the company even thought of diving past the sub's capability? That's a huge negligent suit coming.

See my post #38. I listened to an interview yesterday, the way this thing was put together and maintained was pure sketch. My question is, is it 'certified' or regulated? I am no fat, at all, of government interference in business because, well, government, but I am curious if the .gov signed off on it (whatever government jurisdiction in which it was built or the company is based).

StainlessSteelRat

If that's true, wow, just wow. There was at least one highly experienced person there. I wonder if he was aware of that? We will never know as he's be crushed into oblivion no doubt. If true, that's gonna be one massive lawsuit and the end of that company. Perhaps even criminal charges for the owner.

He was on that sub. It also appears it's been down to the ship before and survived fine. It may of course been the case of the repeated stress beyond its design, it finally failed:

Read this from some German who went on this shitbucket years ago. This operation makes the NASA space shuttles look like solid performers!


It was a suicide mission back then!” exclaimed the Bavarian entrepreneur, recalling his own journey into the abyss. “The first submarine didn’t work, then a diveat 1,600 meters had to be abandoned.”

Loibl explained that they ended up launching five hours late due to electrical issues — which he suspects is to blame for the Titan crews’ current predicament.

Not only that but right before the voyage, the bracket of the stabilization tube — which balances the sub — tore and had to be “reattached with zip ties,” he said.

Several years ago I was looking to do something similar, but waaaaaaay cheaper and simpler. After finding out my life insurance policy would not pay out if I died doing something stupid my wife put her foot down and said no.

Implosion, as harsh as it sounds, would probably be the best outcome. Suffocating at the bottom of the ocean would be a terrible way to go.

Even worse, though, is if they somehow surfaced and are simply not found. From what I read it’s sealed from the outside. Can you imagine surfacing and looking out the window to the outside world only to suffocate because you can’t open the hatch? Really, really feel for these guys and hope it ends well, but that’s unlikely.

The Kursk had such a beacon... it catastrophically failed, almost exactly as Tom Clancy depicted with Politovsky, one of the fictional Alfas hunting Red October.

Me, I wouldn't take a dive like that without a hard cable tether to the ship topside and standing directions that "unless directed otherwise, you yoink us back at time X; from that point again you yoink us at time Y UNODIR; after two extensions you yoink us period barring compelling reason not to."

Never said they weren't, just noting "single safety = single point of failure." (And the irony of fact playing out precisely as fiction, as if Clancy had actual Russkie crews or systems guys tell them their personal waking-nightmare scenarios and put those to paper.) When Grandpa was wrenching on BUFFs, on Huns in Germany and then Sixes at McChord and Osan, each of the nukes on those birds had six separate independent safety systems that if any ONE of them failed to release, the Physics Package wouldn't do its work and you'd just have a very expensive dirty-bomb rather than a fission or fusion reaction.

The sub was supposed to have 7 back up systems to get back to the surface, some which didn't require power as I understand it, which is why I suspect there was a catastrophic hull breach. It would be a real chit deal if they did get back to the surface, but their emergency beacon didn't function. Possible no doubts. Anything in the marine environment has to be meticulously kept up and tested.

Yeah, there have been similar musings among us WWII historians about the Japanese kaiten suicide-minisubs. If they didn't hit the target and detonate (VERY difficult to guide with the limited periscope view) there was no way to return to the mother sub or even to open the hatch from inside and get out so your choices were either suffocate or blow yourself up.

I've stood next to a Kaiten in a museum and the damn thing made my skin crawl... kinda like the schmuck at RAF who wanted to combine Avro Vulcans and Folland Gnat minijets with nukes installed in their noses as a Cold War revival of the Mitsubishi Betty/Yokosuka Ohka "piloted ALCM."

Sometimes it's nice to have someone with several decades of actually doing the job working with you as you go.

Upon further review, my understanding is this thing was designed to gently fall to the near bottom of the ocean and then power up.
If you dont power up you drift.
Now they wanted to slowly fall near the wreck, now add in drift.

You know "room air" is ~ 21% oxygen. You can survive at less; hell, CPR (which I will grant you is right on the edge of life) delivers 17%. Maybe dial down the % (if it's even possible) to make it last slightly longer?

I'm sure it's a very expensive thing to do, but at $250,000 a head, which adds up to a million per trip, they could have survived if they put a little more money into the operational end of things. Anyone alive who is still an investor has seen the end of this business venture.

Honestly, even if it was FREE, I wouldn't do it. I think the Titanic is interesting, but the existing footage is enough for me.

I'd really love to travel to outer space, but even if it was FREE, I still wouldn't do it. I understand risk vs. reward. Now if I were closer to what I think are the end of my days and I have all of my responsibilities tended to, then if it was FREE...I might want to do it.

Definitely seems like implosion was very likely, especially considering the damning info coming from the ex employee who stated it was only truly rated to 1,400 meters. Not surprised if the debris field is from the submersible. Quick way to go I guess. Better than them suffocating to death after 4 days in a feces filled tin can.

Not sure about implosion, the only debris identified were the landing gear and the tail cone, the landing gear and possibly the tail were designed to be jettisoned in an emergency. Hull failure would be a mercy, if the emergency safeguards didn't bring them to the surface and they drifted until running out of air, that would be a bad way to go.

Honestly, the implosion would be as merciful as you can get given the circumstances. Pretty much over before you know what happens. Well in theory anyway. Better than sitting around in a coffin waiting to freeze and suffocate.

Coast Guard guy said the debris were consistent with the pressure tube of the vessel. He also said that they would've picked up the sound of the implosion on their listening devices so it must have happened before they got out there and started listening. Most likely they imploded right at the moment when contact was lost. It's not a surprise considering what we've learned about the construction of the vessel.

Seems like they had a system in place to warn them that there was a problem with the pressure hull.

My guess is that:

They were alerted to this problem, aborted the dive (thus jettisoning this equipment) but the problem persisted and the sub imploded on the way back up to the surface. They never made it to the bottom if they lost comms around 1:45 into a 2+ hour dive.

Ironic that the Titanic herself was a half-ass build in a number of ways despite having many of the world's top minds contribute to her design and construction... what's the point of watertight compartments if water can get OVER the partitions because the compartments either don't go all the way to the uppermost deck or there's no way to seal things off between decks?

Hopefully this generation learns from the hubris and loss on this the way the ones a hundred years ago did from Ismay and Andrews' hubris that fateful April night in 1912.

The Navy passed on that information to the Coast Guard which continued its search because the Navy did not consider the data to be definitive.

"While not definitive, this information was immediately shared with the Incident Commander to assist with the ongoing search and rescue mission," the official said in a statement to Fox News Digital.

Victor Vescovo spent 37 Million dollars to build, test and CERTIFY the DSV Limiting Factor. Cameron and Ballard also mentioned that this is the first fatal accident involving a deep submergence vehicle since man first began exploring ultra deep waters with the Trieste in the 60’s. Cameron himself spent 3 years alone CAD modeling the pressure vessel for his DSV Deepsea Challenger. Sounds like properly built and certified submersibles are very safe to me.

As I said a few pages ago, 99% of the time such events happen, it's due to human arrogance, stupidity and greed. The safety improvements only happen after tragedy, and then the slow process of not keeping up with best practices happens and cycle repeats. At least make it required to have third party testing done as the owner of that sub refused to do apparently.

Truth is, statistically it's been a safe thing, but as more come on line and go deeper and deeper, risks go up too.

The quote from either owner J. Bruce Ismay (survivor), Edward J. Smith or designer Andrews was "God Himself could not sink this ship."

That quote was actually stated by an unknown crew member to embarking passenger, Mrs. Sylvia Caldwell.

However, "There is no danger that Titanic will sink. The boat is unsinkable and nothing but inconvenience will be suffered by the passengers." Was stated to newspapers by Phillip Franklin, White Star Line vice-president…after the Titanic was already on the ocean floor.

There was also WSL literature that said it was “designed to be unsinkable” so pretty close, but not exactly. I would guess this is where the wording changed.

In 1911, Shipbuilder magazine published an article on the White Star Line’s sister ships Titanic and Olympic. The article described the construction of the ship and concluded that Titanic was practically unsinkable.

In my mind the most likely failure point would be the landing gear attachment points and the shock of hitting the sea bed triggered the implosion.

Carbon fiber is strong in tension (good for tanks with high internal pressure), but not in compression, so I'm just in disbelief that they'd think it was a good application for a deep-sea submersible.
Also, the failure modes of carbon fiber are more catastrophic due to their stiffness, vs. metals with some yield before failing. They used the wrong material for the wrong application.

And then refused to have it third party tested so no one could raise any flags and fired the guy who said it was not designed to operate at those depths. It's always a series of humans screw up that leads to these types of events that in retrospect it's hard to believe could happen at all, yet they do over and over.

IIRC carbon fiber also has a spectacular Torsion failure-mode too. Back in the early 2000s a buddy who was hotrodding his Trans Am put in a carbon-fiber driveline that failed, and when it did it abraded itself into oblivion against his transmission-tunnel where a steel one breaking the same way would've shoved a big hunk of metal bar right through that tunnel and directly up his ass. According to him the inside of the TT looked like it had been sandblasted.

The sub story remained headline news for days because of the search drama racing against time before O2 ran out and all that. If on day one it was announced that the sub’s implosion was detected it would have effectively killed the drama that fueled headline news.

So yeah, it makes sense if you subscribe to the notion that the detection of implosion was withheld to keep the sub story in the headlines and drown out (no pun intended) Hunter related news.

As an esoteric exercise I ran a Boyle's law calculation on the change in volume of the air in the sub at implosion

Assuming the inside of the sub was 5 feet in diameter and 15 feet long the interior volume would have been 785 cubic feet. Pressure in the sub was 14.7 psi ( normal atmospheric pressure).

If implosion depth was 11,500 feet, sea water pressure was about 5100 psi.

At the instant of implosion the internal air volume (785 cu/ft @14.7 psi) would have been compressed to 2.8 cubic feet at 5500 psi.
Not a lot of room for 5 bodies in 2.8 cubic feet. That is equal to a box about 17" x 17" x 17".

Interesting. Of course, we are actually bags of water with some air pockets and I’m not sure the exact ratio and the water in our bodies is not as compressible as the air. The other thing is the kinetic energy of the stuff moving around.

I’m surprise no one has done a simulation with a carbon fiber tube and a couple of end caps with some chicken nuggets on the inside.

Wasn’t there some north Atlantic deep diver, decompression accident that happened in the past 20 years were a hatch or some thing failed and a guy got basically extruded out?

Eew. That nasty.

Yep, I think that’s the one. And that was 9 bars what was the pressure delta on the sub?

And an excerpt:


Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.

And that was at a 9 bar differential, the Titan was at 300-400 Bar? Of course, the opposite way, decompression rather than compression.

It is amazing to me how resilient the human body is, but when when you start dealing with industrial sized forces and objects, we don’t stand a chance.

As a teenager I was hit in the head by a rock thrown through the wind shield.

I thought I heard that they think the shovel was headed back up right before it blew in, so maybe they had an inkling. A bad thing would’ve been if the hole had a needle sized hole in it, and the pressure started ramping up before the final crunch. Will never know.

Kick-ass analysis. As James Cameron said in his Deepsea Challenge documentary, the PV on his DSV (Deep Challenger) is made of Maraging Steel, and shrank by 2” during the course of the full ocean depth (36K ft.) dive!! Thus, it was mounted to the sub with straps. A common design I’ve seen across multiple DSV systems.

It really seemed like it should have been obvious from the get-go. Carbon Fiber composites do not react well to outside (compression) stress, and aren’t malleable or ductile..

I’m sure people will speculate that it (porthole) was the weakest link since there are reports that it was only rated for 1300M.

Who knows, could have been blown off in the implosion when the CF failed, or maybe it failed?

Yeah, that's my thinking as well. Titanium endcaps glued to the carbon fiber cylinder. The bond between two different materials under extreme stress would be an obvious point of weakness.

The sub made the trip a few times, the joints could have weakened from repeated extreme change in pressure, repeated extreme load on the joints due to the flexing of two dissimilar materials could've caused them to fail.

Well, anybody here ever seen a truck tire blow up? Those things are filled to around 100 PSI and can go off like a grenade. Or how about one of those oxygen welding tanks falling over and losing it's valve stem, those are about 2000 PSI and can go shooting off with enough force to penetrate through a building. Now think of the destruction those pressures that I just mentioned can generate, and realize that the inside of this sub had 6000 PSI coming in on it! It's difficult to find words that are strong enough to describe the absolute violence and obliteration that must have happened inside there. That's why there's nothing left of the human remains but jelly.

That's interesting. Outside of the actual event, these implosions, at these energies, are really rare in normal life. Explosions, meh. Implosions... You really need a column of water to get a pressure difference like that all around an object.

Take an empty plastic soda bottle on a plane and put a cap on it at altitude and see it crumple when landing... and that is a fraction of an ATM.

Other than deep sea events, can't think of humans experiencing highly energetic implosions naturally or otherwise. I think it's hard to really fathom the energies involved at such depths due to again, it being totally outside of human experience so nothing to really reference there to explain it. Reverse explosion is closest I can think of there.

When I worked in dive medicine/hyperbarics we'd do the plastic bottle thing. Impressed the patients, and most of our treatment profiles were 2-4 ATM. When I worked on the research side some of our dives were 6-8 ATM. The bottle would be squashed flat like a pancake.

One book, they take a nose from a B29 and make a home-built sub out of it. Spoiler, they live. Don’t remember what crime/thing that they solved. Good series of books for a science nerd.
