Titan Submersible

It does annoy me when others take risks and others have to risk their lives to save them.

 

Apparently people who go on it are under no illusions of the risks and sign multiple disclaimers to go(according to guy who has been on it)

 

Have you been down that far WITHOUT coming up for air ?

 

Having watched this clip I wouldn’t be anywhere near this sub.

 

The answer to this is on the tip of your tongue

Obviously you are just learning the trade SD
Us older men have learnt with experience to breathe through our earholes..so need to come up for air...cough lol

 

I think the ‘add a little extra for currents’ is the bit you are underestimating.

 

Jesus Christ. How the **** were they even allowed to take it into the water is incredible. It seems that serious safety concerns were raised back in 2018 but ignored / dismissed.

 

My claustrophobia kicked in just watching that video

 

No.I used go Diving and was BSAC open water qualified so familiar with how current can affect underwater navigation.
Two points . It has already been stated by experts in the field that it unlikely that the craft is mid water. It is most likely either on the bottom or surfaced. Given the extent of the search and also the fact they would have a good idea of the currents at the time they lost contact and subsequent period, they would factor that into the search patterns.2 If it had surfaced they would almost certainly have spotted it by now. If it is on the bottom it is unlikely to have taken all this time to end up there so current is unlikely to have been an influence for most of the interim period. The main problem is GPS and comms don't work underwater and the amount of metal spread over a large area from the wreckage from the Titanic makes Sonar searching harder. As one expert stated it is like looking for a specific mine in a minefield . I have no evidence to back it up and I may be completely wrong but I would not be surprised that if the submersible is ultimately found intact or, hopefully not, they find wreckage of it, it will not be that far from its intended location. Having once cave dived it is difficult to describe how dark it is beyond the scope of the light beams and different from how light behaves in air reflecting off surfaces. The Viz zones are very narrow.

 

All very interesting, thanks.

I'm not a submarine designer but is there any reason why you wouldn't have the weights tethered to the tin can by some form of dissolvable fixing that would give out after say a day of being submerged in water as a failsafe?

 

I assumed that was the surface search. Passive sonar listens for sound although cannot detect range or direction but 3 or more could triangulate in a search. Active sonar can ping outwards like a ball and . It has a range of around 100 miles. Also sounds can travel underwater up to 300 miles. Therefore surface sonar should easily detect a sound only 2.5 miles down. So the 3D element you describe doesn't really IMO enter into it
The whole situation,whilst tragic, is rather odd affect but then using gaming controller to manage life critical systems in an incredibly hostile environment (something like 14 p.s.i on the hull)
seems pretty odd in itself.

 

See #49. That explains why currents are not as significant as you may think.

 

I believe the nearestthis gets is rack weights like a gutter running along both sides with cylindrical weights resting in them . If for any reason the craft tiltsb beyond a certain number of degrees the weights fall off on one side . The craft then tilts the other way and the weights fall off at that side. The craft then gains buoyancy and surfaces. ( In theory) it needs no manual intervention to function but it does need the craft to tilt through loss of stability control due to external factors.

 

Awful to imagine spending potential final hours trapped inside that with knowledge of impending demise.

 

I'm assuming they didn't take much in the way of food and water if the trip was just 12 hours either?

 

It must be awful for them, I can’t imagine to think what will be going through their minds right now

 

I find the way you booked your comments with ‘I’m no expert’, but still felt the need to enlighten us with an essay- absolutely precious..

 

First world, armchair underestimation of the forces of nature..? Impossible. We have the internet.!!

 

I think the oxygen supply takes precedent on such occasions. & I doubt there’s an on board lavvy..

 

After Pearl Harbour, 3 sailors (Ronald Endicott, Clifford Olds and Louis Costin) were trapped in the wreckage of one of the ships (USS West Virginia) - and were heard knocking in the ship. Due to where it had settled and the damage it was impossible to get to them - cutting through the hull was likely to either start a fire/explosion or flood the ship. When they eventually got to the bodies (six months later), there was a calendar in the space with 16 days marked off...
