Missing Sub

[SIRandyraven]

What caught my eye was cost of 8 day holiday/trip at £195,000.
Hope they are all recovered ok.

well the knocking is encouraging, the weights for coming up are on the frame beneath the 'cabin'.....

I don’t think rising to the surface involves weights, DTC. They’ll have ballast tanks I think that allow water in and out. Take water in, the sub sinks - pump it out the sub rises.

//I don’t think rising to the surface involves weights, DTC.//

The vessel has weights which can be jettisoned in the event of an emergency, providing it with sufficient buoyancy to surface without power. The problem is that the vessel is sealed from the outside and the occupants have no way of opening the hatch if they do get to the surface.

In an emergency, yes, Nj - but not in normal circumstances.

[naomi24]

If they managed to get to the surface hopefully the thing would float until spotted - but they’d still be out of oxygen I guess.

anyone reminded of the Kursk disaster from 20 y ago?

Naomi majored in submarine/submersible design ? wonders on AB never cease !

The Kursk was mentioned on page 1 of this thread, PP.

I hope they come out alive, regardless of how much money they have (the latter seemingly being a problem for some people).

It’s all relative, them spending a quarter of a million dollars each could be the equivalent of us spending a couple of hundred quid.

I used to be quite a technical diver, and about 20 years ago I dived on trimix to 100 metres, and getting down is piece of cake, but surfacing took 4 hours including a change from trimix to oxygen. I paid about £500 for this experience (which included a shed load of additional training and gradually deeper dives), because I wanted to try the experience of going that deep on tanks. So to criticise people who have the wherewithal to try something that 99.99999% of us will never have the opportunity to experience is, I feel, a little unfair.

Some people like to push boundaries. If we didn’t, we’d never have landed on the moon.

Military submersibles do have an escape hatch that a rescue submersible can lock on to. However they do not operate at the depth this sub was attempting. No sealed rescue hatch. No underwater recovery especially as there are several bolts secured from the outside on their one and only access or egress hatch. Unless the position is located and they can be bought to the surface, very unlikely at depth, then I believe they are toast. I hope I am wrong.

[LadyCG]

The outlook now is indeed very bleak. We can only hope for a miracle.

I cannot imagine what they're going through mentally. :-(

[naomi24]

DD, that’s what I was talking about. It took you hours to surface because, as a diver, you were exposed to pressure. They are not. They’re in a pressurised vessel so there’s no stopping on the way up to equalise.

[Tilly2]

If they are dead, I hope that they all died shortly after it went missing.

[Deskdiary]

Indeed Naomi, thats why freedivers, which looks terrifying to me, can go to great depths without having to hang around for hours to surface.

[naomi24]

Me too, DD. All about the air in their lungs. Amazing.

[DTCwordfan]

that's why I said the incoming robot would lok to pop the weights out.....assuming that they find the tub in the next two or three hours.....

[naomi24]

PP, to answer your question, no, I didn’t major in submarine/submersible design.

[retrocop]

Sorry to sound like Uncle Albert but when I was a Blue water sailor we carried a EPIRB in our sailing jackets. Electric Positioning Indicator Radio Beacon. Looks like this is a Mickey Mouse operation . :-(

^^^although he appears to have majored in everything.

Funny that.
