This tiny submarine 2.4 miles under the sea, visiting the relics of RMS Titanic. Can it be found and the crew saved before the air runs out?

The United States District Court for the Eastern District of Virginia have the rights over the Titanic site and can decide who dives there and who can take salvage from the Titanic.

I believe that agreement was only ratified by the US and the UK.

It's in International waters - so there's not a lot they can do.

I doubt anyone is going to be taking tourists there in the next 20 years or so anyway.

I predict foul play. Billionaires with WEF links. Suspicious.

What exactly is suspicious about an unapproved sub disaster like this ? Looks very unsuspicious to me.

And are the WEF behind it ? Or someone against the WEF ?

An angry squid ?

But do you take tourists, when pushing boundaries with unproven designs?

Lemme see. How much are they willing to pay?

Ah, OK. Then yes.

 

[T4tomo]

Yes of course he has....

well yes it does appear that he has....

Listen, i'm not saying this was a good, well-designed mission, but it is a fact that you learn something every time you push the boundaries.

I suggest more to learn from the submersibles that have been to the Titanic and lower depths and come back up safely, than this one to be frank. Titan wasn't pushing boundaries, except in cost cutting when making a Deep sea submersible.

I feel sorry for the son who was coerced on by his dad and his poor mother.

The Halibut Mafia. Cross them and you swim with the fishes.

I don’t think posters are taking issues with pushing boundaries, and innovation, just the way the CEO went about it.

That is not what I was responding to, and I think that was very very clear. I have not* said it was OK to take tourist money to do this, merely that out of disaster there would be some - possibly tiny - gains in knowledge.

It's unusual to have unlimited funds. Every project wants to save money where it can [see also: Shuttle O-rings]

"On 15 April 2012, the Titanic wreck, which lies in international waters, automatically became protected by UNESCO, under the 2001 Convention on the Protection of the Underwater Cultural Heritage, which protects cultural, historical, or archaeological objects that have been underwater for 100 years."

Having worked in submarine systems design many years ago, it always seemed a forlorn hope from the moment I heard about the loss of contact.

At those depths, even a minor flaw could be catastophic.

Very much so... Some 300 atm down there, which equates to around 4500 psi. The maths shows just how uncompromising an environment it is.

 

[Reynard]

Stretching my memory back to when I was a marine engineer on subs; and only estimating the dimensions of Titan from published photos, I estimate that to get to the depths required, a cylinder with hemispherical ends would need to be of good alloy steel about 150mm thick.

That would be in the right ballpark, I'd think.

And of course, steel (as do most metals) has the ability to deform without taking damage. To a certain level. Fibre composites have far less wiggle room in this respect - they're strong, sure, but brittle. And cyclic loading is the bugbear of everything everywhere.

A different application I know, but Concorde used to get several centimetres longer during supersonic flight due to the heat and stresses involved.

 

[Reynard]

I wonder why he went with 5 inch thick carbon fibre ?

Lighter for sure, easier to manufacture to a certain extent, as you just keep building up the layers around a mould.

Working with the required thickness and of steel alloys is a much more specialised business.

 

[PaulSB]

What's the biggest design challenge with a sub? The vast pressure differential between a bubble of compressible gas and the outside environment. Why do we have this pesky gas? So that people can breathe.

Solution. Don't take the gas. Don't take people. I've just made your physical design challenge an order of magnitude or two easier. The software challenges are still pretty big, but hey - we like a challenge don't we.

Of course that cuts off a stream of funding from bored billionnaires who have run out of useful things to do.

Spot on.

A Mandrel (fishing rod knowledge )

Is there anything else that lays up 5 inches of CF, and then puts it under compression we know of? (Genuine Q - I don't know)

At least the steel bit is well-proven and tested and tried and safe.

DSV limiting factor

The pressure hull is a 1500 mm inside diameter by 90 mm thick grade 23 titanium (Ti-6Al-4V ELI) alloy sphere machined to within 99.933% of spherical (for enhanced buckling stability). The structure is certified for repeated dives to full ocean depth.[2][8]The hydrodynamic fairing of the outer surface shell is non-structural and removable for access to equipment.
