News Titanic Tours Submersible missing in atlantic ocean

[Doughie99]

I just ran some quick calcs to estimate the "atmospheric" pressure at their depth, which I think is 13,000 ft.

Learned that every 33 ft you descend below the water adds an atmosphere of pressure.

Pressure surrounding them is over twice as high as a full size high pressure gas cylinder. High 5,000s in psi, and they decided to trust that jalopy that doesn't even have half a dozen dives in it's history

yup I ran it thru a calculator and at 3821meters in seawater (official depth of titanic) it comes out at 2500kgs per square inch or 380atm or (like you said) about 5500psi. will crush almost anything at that pressure.

Good. Let it be no more and leave the area alone. A lot of people died for hubris and I think it for the best that it only be a faded memory. I know weirdos think it's cool but it's the marker of a mass grave and no one should be down there fuckin with it in the first place.

What about Gettysburg? 40k people died there. Or Auchwitz

Are there risk of death by visiting these areas?

So if the sub is floating on the surface, is there any way for them to get air or would they still suffocate?

CEO of that company reminds me of a submarine version of Steve Jobs. Just dumber and less competent.

no the only way in and out is the titanium end-cap which is hinged and that's the seal. It is bolted shut from the OUTSIDE so the crew cannot exit on their own even if they're on the surface. But even IF they could open it from the inside the water pressure even on the surface would stop them opening it up (bit like trying to open your car door if you drove into a lake etc), PLUS even if they did, the whole thing would be flooded in 2secs and it'd sink immediately and so they'd all drown.

It's designed to have the mothership crew open and close it once the sub is lifted. It has to be lifted out of the water enough so the titanium end-cap is clear of the water for ingress / egress.

Here's a (timestamped) video where you can see the hinged metal end-cap which is the only way in or out :

Yeah the sound thing is pretty believable, sound travels incredibly well underwater, sonar is how they map the sea floor and whales can be heard thousands of miles away. Especially sound coming up from below the thermocline layer, the water is so dense that the sound travels much faster and further through it.

They started the project in 2017, managed to get to the Titanic a couple years later, I think they had 18 trips planned in 2022, less in 2023 because of weather they say.

I think they’ve said that the sonar buoys could be picking up sound from a variety of metal objects that are down there. I think it’s more a hope that it’s from the sub

Not the same. Both of those also have a lot of historical relevance and there's a perspective to be gained and a thing or 2 to learn . The titanic is just gawking at a car crash turned up to the max.

if it was me inside the sub banging on the metal end-cap, I'd definitely do the signal for S.O.S. which is dit-dit-dit-dahhh-dahhhh-dahhh-dit-dit-dit (Morse code, 3 short signals for "S", 3 longer ones for "O" then 3 short signals).
Any search and rescue mariner should know basic morse code and by tapping out S.O.S. that sends a message it's PEOPLE requesting help, not some random piece of metal banging on some random hard surface.

I'd probably do that "S.O.S." every 10seconds for 5mins, then rest, then repeat every 10mins and just keep at it or handover to another person to continue. Sonar buoys should pick it up and be able to tell direction of the sound (more or less).

Not unless they're rescued. They're bolted in from the outside. It's really their only chance at surviving, though. Even if they found them on the ocean floor, it's not like they can get a tow to the surface. I'd rather not find them there, if I'm the rescue team, because all you're gonna be able to do is tell them that they're fucked.

 

[squeezewax]

Imagine 5 people all crammed in this thing.
Crying and screaming, as well as all 5 having to poo and urinate, the stench!

 

[Ruprecht]

Yeah right, apparently the ballast releases automatically after enough time with the clamps dissolving or some such.

It's going to be really annoying if we don't get closure!

It took a year to find that missing Argentinian sub right? ...But that was obviously a lot bigger.

 

[Brom Bones]

So it goes.

Wasn't that precisely the plan?
I thought the yanks had sent the FADOSS winches etc last night, and the French were sending the Victor 6000?
Still unlikely to be able to find it and recover it while there's any hope of any of them still being alive.

There's tens of millions of cars on the road just in America. Hundreds of millions throughout the developed world.

A yacht large enough to also contain a deep-sea submarine could only be afforded by a relatively few very wealthy people, and it'd have to be located within a certain distance away from the Titanic location.

And that entire area is easily monitored via satalite & radar.

In other words if that 'strict law' was to be enforced, it'd be very easily enforced.

The wreck in international waters. So which country would foot the bill for monitoring and enforcing and under what world wide international treaty would grant jurisdiction?

Frankly I'd rather our coastal defense forces be used to prevent detect/prevent actual crime.

 

[RedBeard_]

Anyway, hopefully some laws will be put into place to avoid any more extremely dangerous deep sea tourist expeditions.
.

Disagree. Besides the people in the sub, no one else is hurt by this so I support letting people do what they want in accordance with their own personal risk tolerance. A small % of people are wired for adventure and just because it's not for you does not mean there should necessarily be a law against it.

Outright banning deep sea tourist expeditions would not be the right thing to do. People should have the right to explore.

However, some regulations that would minimize the risk of this type of catastrophic failure would be a good idea. I get the impression this particular company took some liberties, and that should be addressed with regulations in the future.

Is it even ethical to spend all that money on a rescue effort? That money could go a lot further for other people who need it. Especially with such a small chance of success. Not sure who is paying for it.

Even when there's no hope of rescue, I believe the money still gets spent.
It's not like the year long search for the Argentinian sub or the ongoing search for flight 370 were cost effective.

Is it ethical to not even try and let them for sure die?

So who gets to decide who deserves to live more and who doesn't?

That looks like it was a military operation though. This was a private company operating in a thrill seeking endeavor.

Law of the sea says you assist unless absolutely unsafe to do so.

It will be a search and rescue operation until it's deemed zero chance of survival based on things like remaining air, water temp, ect.
