News & Events Missing Titanic tourist submarine

[Saint]

Would be like me trying to climb Mt Everest in a t-shirt freezing to death, and then an investigation into how I died

And then family complaining that they haven't sent up 6 sherpas and multiple helicopters to bring you home.

it was an absolute P.O.S design, which in addition was over seen with extreme hubris bordering on blatant disregard for safety.
All in the name of "diversity"
C.E.O didn't want to employ "50 year old white men"..
Because they might actually challenge him and tell him he can't do something or it isn't safe to do something a particular way.
And he would also have to pay them a s**t load, compared to a 22 year old.
There...no need to waste millions.
Denial, is not just a river in Egypt.
In summary, that thing made Homers car look good.

A 50yo white guy did challenge him and was fired.

Also didn't this CEO say something like safety is overrated?

looks like they rarely had a successful test either, utter madness that anyone would go on this thing

more like telling everyone they too can climb everest in a tshirt if they pay $250k for you to go with them with your patent pending special am I cold software

and they you convince a few other people to freeze with you and they investigate it but yes

 

[ElectricG]

Why?

I find it interesting and I wanna know everything.

Patent-pending carbon-fibre self-heating and drone-installed t-shirt.

Did Stockton get the design for the sub by taking a dump? Snapped one off and thought, yeah that's got a good taper and sunk real nice, pretty nuggety too, I'll call it a titan.

if humans get effectively vaporised at that depth, how are fish just chillin down there?

Remember the fish have evolved for that environment with a range of adaptions for extreme pressure. They won't survive lower pressure. The real deep dwelling organisms, > 3000m, have no gas containing structures like swim bladders or lungs, so everything in their body is at the same pressure with no pressure differential. They have special molecules (piezolytes) to prevent proteins collapsing and high levels of TMAO helps also stabilize structural proteins. Small bodies and specific shapes help.

Other than the pressure, the environment is literally freezing cold, completely dark and has very low oxygen tension in the water, another reason they tend to be small and slow.

What is really amazing are the mammals that can go down to 2500-3000m, because they have to do it with lungs, an even more difficult problem for them to handle. But that's another story.

The Conversation has an interesting article talking about the problem of hull materials

What was the ‘catastrophic implosion’ of the Titan submersible? An expert explains

Deep underwater, the Titan submersible would have been crushed in less than a second once a defect cracked the hull.

theconversation.com

Carbon fibre while very hard is brittle and lacks the ductility of metals and the article suggests it may be the difference in behaviour, between carbon fibre and the titanium, especially over time with repeated dives. Composite materials also risk delamination if poorly made, any one with a 3D printer will know about the problems of delamination. I'm not an engineer but one of the things that strikes me is that there is no history of using these materials over the long term in this hostile environment. The metals used in subs have long histories, with known properties and understanding of how they fatigue over time. None of this exists for the material used in the Titan. From reporting in the public domain it appears they didn't even test them. Like the late CEO said, can't let safety get in the way of innovation!

Added - this is a BBC article that talks about adaptions to the very deep.

How do fish survive in the deep ocean?

Scientists have recorded the deepest fish ever on camera. How have animals adapted to survive in the dark, crushing depths of our oceans?

Right, but spending millions of dollars because it's "interesting" is pretty dumb, no?

 

[Gralin]

I find it interesting and I wanna know everything.

You can't work out why it imploded?

Seriously carbon fiber isn't designed for this, they never certified it, they used it multiple times for something it was never tested for, with a viewing portal that was 100% not rated for the depths the were going to.

It was literally just a matter of time.

Improving standards for what? For other crazy millionaires who wanna use untested unsafe homemade submarines ??

 

[Gough]

In the end it was pretty much the same effect as dropping a brick on a wine glass.

 

[peternorth]

Wowwwwww
I was trying to explain the implosion to my son this morning and the psi bits and bobs were difficult for me to communicate. Might show him some of these videos so he can visualise it.

If there's one positive to come from the brave sacrifice of the Titan passengers, it's that this may unearth budding and future scientists, engineers and marine biologists.

The only less productive week I've ever had was during the Thai cave rescue.

I'll never forget the day and days thereafter when Timmy O'Toole fell down the well.

 

[Toump Ass]

Yeah well, maybe we charge Hamish MoneyBags' estate for it?

I want to know grisly details, I want to see re-enactments. I need exact figures on how many pieces they blew up into.
"For science"

Interesting to read that a single little bubble in the carbon fibre could have caused a catastrophic failure and this clown was refusing to do the standard hull checks during testing. Clearly a narcissistic arseh*le who would not listen to anyone or anything, it’s a pity his attitude has taken the lives of innocent people.

Not sure if linked previously;



This is a railway car with a ~ 15psi vacuum.

The pressure at 3500m is closer to 5500 psi.

Would recommend listening to James Cameron's interview with CNN.

To paraphrase, he heard from sources in the deep diving community that a loud explosion was heard around the time of the accident. That the only thing he could think of which would cause 2 separate system failures was that the sub failed. He also said that because they used an "alloy", every time they went down, the significantly weaker the material got. That it would have been difficult to tell this was happening.

 

[faible]

That it would have been different to tell as well.

AFAIK from aviation / cycling the only way to check the structural integrity of carbon fibre shells are with an xray, which Rush told the engineer he fired, that such an xray doesn't exist for carbon fibre of that thickness.

Play stupid games, win stupid prizes. Unfortunately, whilst Rush probably got the fate he deserved given he actively made the decisions that created a submersible that was a ticking time bomb, the others (especially that 19yo who sounds like he only did it for his old man) really likely had no idea just how dangerous it was.

The only small solace is that given the list of shitty ways to die they had available to them, instant death by implosion was the best.
