Titanic tourist sub goes missing in Atlantic Ocean, June 2023 #3

[arielilane]

The wife of the OceanGate CEO who was piloting the submersible that disappeared during its voyage to the Titanic wreckage is related to a first-class couple that perished the night the famous ship sank in 1912.

And, one more link about Cameron.

Obviously, I found the info fascinating (as I was unaware)

So does that mean above or next to?

1600 ft off the bow of the Titanic.

If you mean were the passengers able to see the Titanic before the implosion, napkin math tells me it was a couple of football fields away … and I assume (but don’t know) that the sub’s lighting wasn’t strong enough for that, just for a start.

The debris was found on the ocean floor. Don’t have a source handy, definitely read it, I think that came from the coast guard.

That’s a shame.

I’d like to learn about those other vessels. I really didn’t understand much of anything about this prior to this tragedy.

I recommend reading about Robert Ballard and how he discovered and filmed the Titanic and other ship wrecks, and the things that happened after his finding.
I recommend his Nat Geo. videos and books.

Do we know they were trapped down there for days, alive? I was under the impression the implosion happened when they reached the depth of the Titanic.

I think you might have misread me, I said essentially it COULD have been worse, thank goodness they weren't trapped down there for days alive, when that kid would have rather been anywhere else.

MOO

I do not know much about subs or pressure, but have any of the experts or people on here said if the passengers would have been aware that they were about to face a catastrophic failure moments before the implosion? And if the implosion would have been "very loud," wouldn't the Mothership have heard it when it happened? Especially if it happened in the mid-depth water column; not at the very bottom?

In all probability they were dead before they knew anything had gone wrong, which can be considered a blessing. The implosion would have been loud compared to the normal background noise of the ocean, but it probably wouldn't be loud enough to be heard at the surface without specialist equipment.

If anyone has seen the movie Raise the Titanic, a submersible implodes in that movie. They show water rushing in as the crew battle to save the sub at about 11,000ft. Totally unrealistic. In reality, even a slight leak would cause water to rush in at 6000psi, slicing through like a jet cutter. The inrush of water would be so sudden and ferocious that the occupants of the vessel would almost certainly never know it had happened.

Just about everyone can visualize an explosion and the damage it does, because explosions are common. An implosion is the same thing in reverse. Just as sudden, just as destructive, but instead of everything expanding outwards it's crushed inwards.

I've defended some aspects of Titan's design, but one thing I'll never defend is the tubular shape of the pressure hull, which I can only think was done to fit more paying "crew members" on board.

Normally subs designed for this kind of depth use a perfectly spherical pressure hull. The sphere is inherently much stronger than other shapes because the force applies equally in all directions; there's no inherent weak spot. Spherical hulls have been used successfully on pretty much all previous deep sea vessels, and up to now none of them have had a catastrophic failure.

IMO, by making Titan's pressure hull tubular, it was always going to be much weaker than it should have been.

I'm guessing CEO Rush did not know any of this. And he fired the one guy who was trained in such matters (and who wanted NDT and different designs).

The loss of two super bright minds in the deep sea exploration world is huge, I imagine, for everyone in that scientific community. So much information, experience and potential from them is lost to their community.

I know he designed and built a submersible.


Here's an article from 2012

Mr Cameron has spent the past few years working in secret with his team of engineers to design and build the craft, which weighs 11 tonnes and is more than 7m (23ft) long.
He describes it as a "vertical torpedo" that slices through the water allowing him a speedy descent.

Whoa. Thanks!!

“Crushed inwards”

Can you please elaborate, would that mean it’s contained?

Statement from our Principal | University of Strathclyde

www.strath.ac.uk

"I feel disbelief," Azmeh said, speaking through sobs. "It's an unreal situation."

"I feel like I've been caught in a really bad film, with a countdown, but you didn't know what you're counting down to," she said. "I personally have found it kind of difficult to breathe thinking of them."

"I never thought I would have an issue with drawing breath," she added. "It's been unlike any experience I've ever had."

Azmeh and Shahzada are scions of one of the most prominent corporate dynasties in Pakistan. The family’s namesake business empire, Dawood Hercules Corp., has investments in agriculture, the health sector and other industries.

Shahzada was the vice chairman of the Karachi-based Engro Corporation and an adviser to Prince’s Trust International, a charitable organization founded by King Charles III.

In recent years, Azmeh had fallen out of touch with Shahzada. ​

She was diagnosed with primary progressive multiple sclerosis in 2014 and "reduced to being in a wheelchair." She and her husband decided to move from England to Amsterdam so she would have easier access to medicinal cannabis.

Azmeh Dawood, the older sister of Pakistani businessman Shahzada Dawood, said her nephew was reluctant to go on the Titan expedition.

I've found this a difficult one to process and rationalise.

sbm and same here, I've had a stomach ache for days and now I will not be able to eat for a month at least.
I still have that young boy in my head, just hoping they just went poof, no scary thoughts in their minds =*(

 

[CrimeDawg123]

I think there's probably a lot of important or scientific and engineering data that can be gleaned from this crash by analyzing the surviving wreckage.

Just as the NTSB does post-crash investigations which make air travel safer, I hope one good thing to come out of this will be that the knowledge gained will help build better, safer DSVs.

Really? Why? Air travel is a necessity in modern life. Travelling to the depths of the ocean is a luxury that taxpayers need not fund IMO.

Titanic sub passengers died instantly in ‘catastrophic implosion’; wreckage from doomed vessel is discovered on ocean floor

A remotely operated vehicle discovered a debris field while searching the site of the Titanic’s wreckage for the missing OceanGate submersible, the US Coast Guard said.

The implosion happened well before the Coast Guard got there, IMO.

No sound monitoring from the CG at that time.

IMO.

I've only read the first couple of paragraphs but I wonder if all of these people voiced their concerns at the time they took their submersible excursions (or was it only Pogue that did so?) ?? If so, who did they speak with about these dangers?

 

[cuffem]

Whoa. Thanks!!

Dr. Ballard/Woods Hole was the first with Alvin. to be fair Cameron was making a movie.

I think from what's been said it imploded some distance above and to the side of the original wreck, but I've also seen it said somewhere that it may have descended too quickly and impacted the sea floor. At this stage, I think it more likely it imploded some distance above the wreck because of the time they lost communications.

MOO

Yes, I believe the admiral mentioned something about within the water column.
