Hopefully a good outcome ahead.
Sub named Titan.
What an amazing feat by search teams if they have indeed found it so quick.
A the start of this earlier this week, it was being reported that he was 15. This may have been corrected since. I.don't know.
Testing it under pressure is a hugely difficult exercise for anyone, not just this crowd. You would need to construct a high pressure enclosure into which you could put the submersible, box it all up and then pressurise the enclosure to 200-400 bar. Bear in mid that the subs have small hatches, view ports etc because of the difficulties of sealing openings, but your test enclosure would need a door large enough to fit a sub through. Such test chamber do exist - there's one in Scotland - but they don't go to the pressures that the Titan experienced, only about 100 bar / 1000m in this case.
True enough, your suggestion of lowering it, unmanned, on a tether to a suitable depth has a certain practicality to it but it's not infallible. The Titan had dived to the Titanic previously so simply submerging it was no guarantee against failure
Bear in mind that every big military submarine in existence was not pressure tested before it went into sea trials. Non-destructive testing of all the fabrication, pressure testing of particular components can be carried out but the tests of the entire assembly are carried out "live", at sea.
Regarding carbon fibre being a "no-no" - that's not a given. Submarines constructed of what we might regard as "proper" materials such as steel or even titanium that have failed catastrophically at shallower depths in the past . And there are composite vessels in the LNG industry rated to 3000 bar internal pressure, so it is possible to construct for high strength applications.
There was a 15 year old on it? I knew of a 19 year old.
it lost comms all the time and seemed to have a very patchy record of actually finding the titanic, a lot of luck in finding it
going by the video they were able to monitor its position though
I doubt very much any remains will be recovered. If they didn't vanish with the initial implosion, I can imagine the marine life will see to the rest.
Logically given it was only 15 mins away from the Titanic when communication was lost and implosion was greatly the most likely scenario it was the best place to start.
And it was. Given it was an implosion rather than an explosion nothing's going to go too far, the tube and the occupants are sadly probably in a million tiny pieces though.
Its also a bit ridiculous that the Polar Prince did not have its own ROV.
has this been posted?
unreal
Impressed how quick the ROV who only set off this morning US time found debris. Only a matter before debris from the hull is located.
My heart goes out to the mother & family of the 15 year old boy. He would never be able to compute the risk involved or understand the lack of regulation / oversight relating to the craft or the company itself.
sure you have answered your own question
Yes it could have been pressure tested. Apparently to cut on the costs of regular scanning the hull was monitored sonically for stress detection. This is used for the likes of Forth Bridge where it is obviously impractical to scan, but for a vessel the size of a van it was just cost-cutting.
Do we think there is any chance of recovery of the bodies, since the implosion would have more than likely completely destroyed the bodies.
We must remember that this was not like a leak and it filling up with water and they drowning. This is more akin to them sitting on one of Daisycutter bombs the US used in vietnam, and setting it off. The power and force of an implosion at those depths is difficult to comprehend.
My prediction is that there will be no "bodies" recovered, perhaps a few bits and scraps and some twisted scraps of wreckage, but nothing recognisable.
I expect not much chance of recovery of remains in this scenario?
So this will be their graveyard. RIP.
And the design seems to be mostly done by Stockton Rush.
it is, they didn't gave a clue where it was, it must have imploded right by the titanic and not budged, like even with the implosion it still has ballast that would detach and it could float off, maybe those sections have
No.
Boeing and the University of Washington have denied having anything to do with it. Oceangate claimed they 'worked with partners at Nasa' to design the hull. Nasa has not commented yet.
There is a video of the sub being constructed. A lot of it seems to be in OceanGate's own workshop. Some parts were made externally.
Not really in fairness…. Today is the 1st day they had ROV’s on the seabed near the Titanic, so they were bound to find something…. And will no doubt find the rest of it in due course
RIP.
Yeah, most likely the crew didn’t even feel it or know it was happening…
At best they might have sensed a flash, but before they could even process that it was already all over.
its amazing they found anything
At those depths and pressures, it would be like an egg versus a hand grenade.
The implosion would be absolutely instanteous, totally catastrophic, and the occupants would not only be killed instataneously, but their bodies would be utterly pulverised by the massive implosion.
The mind boggles. Rip to all.
Is there no way of testing it under serious pressure? Was it done?
Before men go down in it why wasnt it attached to a tether and sent down on its own. Jesus christ. Amateur hour. Simple mistakes get you killed. Carbon fibre is a no no at those depths.
A lot of people thinking they are being very funny on Twitter atm.
These guys too were known to be sanguine, they knew there was significant risk and even if they briefly knew their fate was sealed they very likely would have thought “que será”.
Yeah.
I think the Coast Guard were pretty sure anyway. Of course that area is littered with debris, but the debris is covered in 110 years of coral and algae. Fresh, clean, white debris is pretty conclusive.
The tail cone & landing frame
Theres a legal dispute atm over who is responsible for what. It was quite evidently not fit for purpose it was used for. I’m quite sure NASA & Boeing would refrain from offering flight crew a Bluetooth device for control.
Its confirmed. It is the titan.
'The only saving grace is that it would have been immediate - milliseconds', says friend of passengers and rescue expert A rescue expert who knows two of the passengers on board Titan says "they don't use phrases like debris field unless there's no chance of a recovery of the men alive".
David Mearns told Sky News that the coast guard doesn't use phrases like debris field "unless there's no chance of a recovery of the men alive".
"A debris field implies there's a break up of the submersible and at that depth, because we know that they lost communications at around 3,300m… so that really indicates what is the worst case scenario which is a catastrophe failure, an implosion," he said.
Speaking about if there has been an implosion, he said: "The only saving grace is that it would have been immediate, literally in milliseconds and the men would have no idea what was happening".
He added that that was his "fear" on Monday morning when he heard Hamish Harding, one of the five men on board Titan, was missing in a submersible.
Mr Mearns said: "They told me it was the dive on Titanic, that it was the first dive, that's a bad sign. That it was on ascent, that was a bad sign and where comms were lost. So my worst fears have now been realised."
Mr Mearns says he knows both British billionaire Hamish Harding and the French sub pilot Paul-Henri Nargeolet.
