Submersible wreckage brought to surface.

[thastinger]

I figured it would be because of human remains/blood.

There aren't any "remains" at that depth, not even fillings for teeth.
Have to remember that the vessel was filled with air, when you compress air it gets hot, it was a mini star inside that thing for a couple of nanoseconds.

Isn’t it interesting how that there was not one peep about this expedition submersible before the tragedy? Most people didn’t even know it existed yet afterwards there are loads of experts and pundits talking about how unsafe it was. Where were all these people a month ago?

My guess is, the Titan sub tragedy gained attention because we did not know if the people were alive. It spanned days... Human nature makes us hope some super human rescue mission, miracle, whatever, would occur. The Titan was not have have a Hollywood ending.

Just my 2 cents.

Most of the real experts in this field tend to involved with competing operations, so they may have been dismissed as trying to stifle competition. Regulations should apply to any vessel when it is in buisness carrying passengers for hire though.

Even if they were, this company was warned directly about the design of this vehicle by several people. They decided (they being the CEO Mr Rush) to ignore the pleas and warnings and go forward because in their mind innovation is stifled by regulations. And while a good argument can be made for that, carbon fiber has known limitations that require much more attention and care be paid to construction, maintenance, and repairs than either steel or titanium. He ignored all of that knowledge.

Oh yeah absolutely.

I heard one expert say the pressure would have hit at about 1,500 MPH. The occupants never felt or knew anything; their minds would take longer to recognise the event. They were, in effect, vaporized. So sad.

Any structural vessel, be it a submersible or an aircraft, has to be limited to so many compression/decompression cycles.

This vessel may have exceeded those cycles.

Not sure if ghoulish but maybe in bad taste for the Washington Post to run this full page ad today from Omega for their Planet Ocean Ultra Deep watch good down to 20,000 feet.

Sounds like they are saying that even though the passengers didn't make it, their watches survived.

Both notions are utter nonsense. Should carmakers pull car ads because people die in car accidents every day? No watch can survive essentially simultaneously occurring combustion and rapid compression.

The water resistance of a watch is based on static pressure - that means if you as much as jump into the water, if you flail your arm underwater, or if you use a scuba scooter, pressure increases dramatically. That's why a watch has to be 100 meters/330 feet water resistant to be suitable for surface swimming and snorkeling while proper dive watches not only have to be at least 200 m/660 feet water resistant but they should also be ISO 6425 or DIN 8306 certified which means each individual watch has undergone rigorous testing and certification. Anything >200 m WR is about redundancy. If you buy a watch with an uncertified water resistance rating and get it wet you have chosen poorly if this particular watch is part of the kit you rely on.

From what I understand carbon fiber grows cracks as it is subjected to compression cycles, and has to be replaced far sooner. And the CEO told someone he knew he had also used fiber that was expired / beyond its use date in the construction of the pressure hull. Kind of sounds like a recipe for disaster to me.

 

[alarmguy]

Ho hum I’ll say.
It’s a media event for advertising dollars.
Who cares? It’s a day in the life of being human.
Over 1000 Americans die every day do to medical mistakes and car accidents.
5 people on an Expedition in international waters didn’t make it on an adventure much less than even deaths on Mount Everest this year.
Don’t waste our tax money please!
It’s nuts!

And beyond that, what material was the frame ribs composed of and how many cycles can they withstand?

 

[billt460]

That's what I thought. OTOH I doubt there would be any traces of that considering the wreckage had to travel about 12,500' to get back to the surface.

12,500 ft. through seawater is one hell of a rinse cycle.

But how do you regulate someone working in the middle of an ocean in international waters? I have no idea about maritime laws though, maybe the country of origin can regulate?

What tax money was wasted?

 

[TCL]

Imagine finding one?

Good advertising...if they find one!

Am I the only one surprised there is a ship with 4 miles of heavy cable just ready to go to haul this junk up?

 

[demarpaint]

I think carbon fibre tube will be a shredded tangled mess with maybe no large pieces at all, as it imploded and then probably the compressed air in the vessel exploded with the 300 to 1 compression ratio... The titanium end caps may be in one piece and dented a little...
I don't think they are searching for bodies, maybe teeth would be recognizable?

I was thinking along those lines as well. Teeth, maybe. May they RIP.

Not sure when it’s considered waste - (all hands on deck) - but there are always knock on effects of emergencies at sea - like whomever needs that vessel back …

A rather costly way to hit Mach 2 I'd say...

I saw an interview with James Cameron. He has been down to the Titanic wreckage a total of 33 times. And to the bottom of the Marianas Trench. He said he wishes he had spoken up sooner about what a total (edit-Mod) that thing was.

The only one I feel sorry for, was the 19 year old kid. His grandmother said he didn't want to go on it. And was in fact terrified to make the trip. She said he only went to please his father. The others were culled by Darwinism, and extreme arrogance.

100% feel the same way.

There's a need for it all the time in scientific research, exploring / salvaging wrecks, working on undersea telephone cables, etc.

Don't hear much about it since it is rare to have a manned mission and when they do there are a lot more safety precautions.
