Sub Update Catastrophic Structural Failure.

Dr Molé said: 'The pressure hull is the chamber where the occupants reside. It sounds as though they had reached the bottom when the pressure vessel imploded, and usually, when it gives way, it gives way all at once.

'It sounds like it was the carbon fiber cylinder that gave way and resulted in the implosion.'

How the pressure chamber was breached remains unclear. But such an implosion could be due to a leak, power failure, or small fire from an electrical short circuit.

What would have resulted would have been a violent and instantaneous implosion as the high pressure water outside flooded in, wrenching away the rear cover, landing frame, and ripping apart the sub’s hull, crushing those inside.

While I understand not wanting to divulge the sensor, I don't understand the delay in reporting. It's not like Titan was on a mission to blow up the Nordstream II pipeline. Between the navy and Cameron's revelation that Titan had dropped ballast and was returning to the surface, it's pretty clear on Sunday people knew this was a recovery operation, not a rescue operation.

Sub passengers died in implosion

The five men onboard the missing submersible in the North Atlantic died in a catastrophic implosion, the U.S. Coast Guard said, after searchers found debris from the craft near the Titanic shipwreck that ended a desperate search to find them alive.


US Navy detected Titan sub implosion days ago

WASHINGTON—A top secret U.S. Navy acoustic detection system designed to spot enemy submarines first heard the Titan sub implosion hours after the submersible began its mission, officials involved in the search said.

The Navy began listening for the Titan almost as soon as the sub lost communications, according to a U.S. defense official. Shortly after its disappearance, the U.S. system detected what it suspected was the sound of an implosion near the debris site discovered Thursday and reported its findings to the commander on site, U.S. defense officials said.

“The U.S. Navy conducted an analysis of acoustic data and detected an anomaly consistent with an implosion or explosion in the general vicinity of where the Titan submersible was operating when communications were lost,” a senior U.S. Navy official told The Wall Street Journal in a statement. “While not definitive, this information was immediately shared with the Incident Commander to assist with the ongoing search and rescue mission.”

The Navy asked that the specific system used not be named, citing national security concerns.

Wouldn't the domes press against the hull underwater, effectively self sealing making the adhesive only relevant at low pressure near the surface?  I doubt the glue is structurally relevant at the depth at which the beer can failed.

If you have two different materials that expand or compress at different rates, a sealant/glue is going to have to be chosen very carefully to keep it from detaching from the part/piece that has the less adhesive surface.

Exactly what glue or epoxy resins can withstand the pressure involved?
With the differing rates of compression between the two different materials of titanium and carbon fiber I cannot imagine that there is any glue or epoxy resin on earth that could withstand the compressive forces once lowered to that depth and then being able to expand back to its natural state once it's brought back to the surface.

Completely ridiculous. It's my guess the bonded joints failed and within the millisecond that water entered the failing bond between the dissimilar materials.
The adhesion between the titanium and carbon fiber gave way. I'm surprised it actually held up for more than one cycle.

Saw the video on the construction. The vessels were glued on to the outer ring of the carbon tube. Saw nothing about the inner surface. Seems like a titanium inner ring would have strengthened against stretch and compression vs the outer vessel

Or, the mother ship didn't disclose everything to the press, but did to the Coast Guard, that they had received a message from the sub that they had dumped ballast & were ascending just before comms were lost.  In which case, it doesn't make much sense they'd wait hours & hours before notifying the Coast Guard.


Seriously. They knew there was an emergency going on and waited several hours to tell anyone else?


Given the previous communication failures, if the emergency occurred after comms loss, the mothership could just be expecting their risk-taking CEO to go down on the normal dive, & they'd regain comms a few hours later as normal.

It may be they made a quick call to the US Navy, who then picked up the implosion on SOSUS (or whatever they call it today), as that information has apparently been published.  So everyone at the top of the search has pretty much known since the beginning there was no chance.

Damning is exactly how I'd describe that interview. Criminally negligent CEO and likely others.

Others in the industry wrote letters to Oceangate telling them it was too experimental for passengers and needed to be certified.

US Navy heard it

“The US Navy detected an acoustic signature consistent with an implosion on Sunday in the general area where the Titanic-bound submersible was diving when it lost communication with its mother ship, a senior Navy official told CNN.

The Navy then immediately relayed that information to the on-scene commanders leading the search effort, and it was used to narrow down the area of the search, the official said.”

I'm seeing a lot of people are making this same mistake (not just here).  If it was a true "crush" event, the issue is that there are two things going on at the exact same moment.

1. Yes, it is water and it is under pressure (a genuine triple metric shit ton of pressure).  But, lots of people are forgetting that the water itself has mass.  Imagine if you will, you're in a 6'x6'x6' box, and sitting on top of the box is a 6'x6'x2.5 miles high column of water.  And suddenly, the roof just gives way.  The entire column of water above you is going to instantly slam down on you to fill the void.  You will be completely pulverized, not just crushed or slammed against the other wall, pulverized into paste.  No intact bones, no meat, just a compressed glob of water soluble goo.  Similar to a shipping container being dropped onto a tomato.  Squash, "damn, that don't look like no tomato I ever saw."  There may be chunks of flesh and fragments of bone floating around, but no recognizable corpse or peices that could be identified as part of such.

2. Now the triple metric shit ton of pressure issue.  This is where lots of us are using the term "Dieseled".  The worst case ambient pressure is (more or less) 5550 psi.  Divide that by 14.7 and you get an increase of pressure that is a factor of 377.55 times what is inside the container.  Air follows the "Ideal Gas Law" and volume is a direct inverse of the pressure, double the pressure, the volume is reduced to 1/2, triple the pressure, volume reduced to 1/3.  So, when things went to shit, all of the gasses (air) inside the sub got crushed into a volume 1/377.55th of the original volume. (If you know the actual internal volume of the cylinder, that ratio will tell you the volume of the resulting "combustion chamber").  Normal diesel engines operate at between 300 and 400 psi because that is what it takes to make enough heat for the diesel liquid spray to ignite.  For a brief moment, our cylinder reached an operating pressure of 5550 psi.  At that pressure, the heat was enough that things that don't normally combust, suddenly do, an explosion.  But only for a brief moment, then the volume of water flooded the space and put the fire out.

And, all of this happened in a very small fraction of a second.  They were dead before they could recognize that it was happening.

So, recovering the bodies?  No, there really aren't any to recover.

In theory, the bodies might be intact but pulverized internally? Sank to the floor and were carried away by currents or are the bodies just floating in slow motion neutral buoyancy


I'm seeing a lot of people are making this same mistake (not just here).  If it was a true "crush" event, the issue is that there are two things going on at the exact same moment.

1. Yes, it is water and it is under pressure (a genuine triple metric shit ton of pressure).  But, lots of people are forgetting that the water itself has mass.  Imagine if you will, you're in a 6'x6'x6' box, and sitting on top of the box is a 6'x6'x2.5 miles high column of water.  And suddenly, the roof just gives way.  The entire column of water above you is going to instantly slam down on you to fill the void.  You will be completely pulverized, not just crushed or slammed against the other wall, pulverized into paste.  No intact bones, no meat, just a compressed glob of water soluble goo.  Similar to a shipping container being dropped onto a tomato.  Squash, "damn, that don't look like no tomato I ever saw."  There may be chunks of flesh and fragments of bone floating around, but no recognizable corpse or peices that could be identified as part of such.

2. Now the triple metric shit ton of pressure issue.  This is where lots of us are using the term "Dieseled".  The worst case ambient pressure is (more or less) 5550 psi.  Divide that by 14.7 and you get an increase of pressure that is a factor of 377.55 times what is inside the container.  Air follows the "Ideal Gas Law" and volume is a direct inverse of the pressure, double the pressure, the volume is reduced to 1/2, triple the pressure, volume reduced to 1/3.  So, when things went to shit, all of the gasses (air) inside the sub got crushed into a volume 1/377.55th of the original volume. (If you know the actual internal volume of the cylinder, that ratio will tell you the volume of the resulting "combustion chamber").  Normal diesel engines operate at between 300 and 400 psi because that is what it takes to make enough heat for the diesel liquid spray to ignite.  For a brief moment, our cylinder reached an operating pressure of 5550 psi.  At that pressure, the heat was enough that things that don't normally combust, suddenly do, an explosion.  But only for a brief moment, then the volume of water flooded the space and put the fire out.

And, all of this happened in a very small fraction of a second.  They were dead before they could recognize that it was happening.

So, recovering the bodies?  No, there really aren't any to recover.



Can you run a quick ideal gas law calc to see what kind of theoretical temperature it might've gotten to?

My guess is both titanium end caps and flanges are intact

Well, obviously they were intact enough to recognize them in the debris field.  It's looking more to me like the CF tube imploded, blasting off the end caps.

Are there plans to bring the wreck to the surface and cut it open to drain the people out?

Probably not as this thing is probably a small debris field and there’s not much left of the occupants between getting crushed by implosion and then all the sea critters having a snack.

In fairness, the article(s) prey on the idea that he knew what we do- that all indicators point to this being  a sketchy operation. I’d be terrified of going down that far in a vessel that had 1000 successful missions- and I’ll bet most people would be as well.

The sad irony is that they went to visit a gravesite and now they’re a part of it
