Titan submarine accident

Also, just to be clear this was it's 14th excursion to the Titanic wreckage. RIP.

 

14??? And probably never re-checked for any damage after the first couple, then it was "proven"

 

They are not going to find any bodies or even remains. Suppose the pressure was 5,000 PSI. Put a wall to your left. one to your right. Call the area of your body 5 square feet = 720 sq in. Those two walls propelled by 5 000 PSI would hit you with a combined force of 3,600,000 lbs = 1,800 tons. Squish! Nothing but jelly.

 

Not trying to be crass.
One of the "benefits" to this fiasco, is the great number of people that did not pay attention in science class in school, or partied to hard in college, are doing some research and learning a good bit about physics, physiology, and other topics.

 

Yea, I figured they probably didn't even register the implosion. Which is a blessing of course.

 

If they want to go down with a chicken wire & bubble gum machine fine , taking the teenager is beyond reprehensible .

Again, I am not going to bash anybody. It has been mentioned here that hull designs are calculated for a specific number of cycles. An example would be the Aloha Airlines 737 that blew a significant part of it's fuselage off in a flight over Hawaii. The pressurization life of that 727 was 75,000 cycles. When the fuselage finally failed, the airplane was at about 94,000 cycles. There was still enough of the airplane to land it under control. In the case of the Titan, obviously the cycle life of the vessel had not been correctly calculated. Hopefully, the takeaway from this is that things like cycle-life will have to be established before we do this kind of thing again. We learn from our mistakes. Sadly, some of those mistakes result in the loss of life.

 

Per my previous post, we DID learn something.

Have you ever seen the implosion/collapse of a tanker trailer? Imagine it being made of carbon fiber. Instead of a violent collapse of metal smashing them, it would have likely shattered around them, shards of CF hitting them, razor sharp from all directions. It's a good thing they were already dead.

My question is, did they hear it starting to give? It collapsed so quickly, I wonder if they had a moment to ponder their demise or if the CEO said it was normal?

I have never designed a submarine, but if that is the pressure hull...

 

You are not wrong. But subs normally have a double hull.

 

I’m sure they put some Permatex on the threads…

At 9000 feet below the surface, the implosion would have had structure moving at the 2000 feet per second. Think rifle shot, or Mach 2 or 1500MPH. These folks would have been dead in a couple of nanoseconds and far faster then they could even receive a signal to the brain that anything even happened. Not to mention, the extreme heat and pressure spike would have resulted in a spontaneous detonation/combustion. Over before they knew anything.

And the entire time the vessel is descending, it is experiencing continual noises from the pressure exerted and popping, creaking, groaning. So, they "never heard" the one that got them.

Think lighting hammer hitting an ant on an anvil. Just, gone in an instant.
When you hear people talking about "they died instantly", this is a literal reality in this case.

Retired USAF, I know a thing about pressurization, negative pressure effects and catastrophic failure of quite a number of components. I have experienced/seen things.

My cousin was a Navy Bubble head (Nuke guy), we talked about a lot of this stuff.

He feared a Kursk situation and welcomed the implosion if anything ever went wrong.

 

Based on the photos of its construction I have seen, that seems unlikely. How many hulls capable of over 5000 psi can one fit there anyway?

 

I read a article that sharks that had tracking devices on them started to head to the site.

 

Those are actually frickin' laser beams attached to their heads!

 

Well that would be incredibly stupid. But from what I have read the owner did not take safety super seriously.

 

When one of the news channel showed the names and pics of the deceased it mentioned the teenager was petrified of going but his Father wanted a bonding moment.
