Titanic Tour Submarine Missing.

i don’t think they thought that this would happen, think about essentials, food, water. And the bathroom!

I wonder if Harbor Freight will replace those bad components?

Only if they paid for the extended warranty at checkout

I think this is the harsh reality. If they are alive they are suffering from dehydration, there’s piss and shit in that make shift toilet or worse on the “floor”.

Odds are someone panicked and god only knows how that was handled.

Cabin fever is a whole another level 12,000ft below in a tin can.

Hull taping - proper Morse Code wouldn’t be needed. Any taping would help. But, it sure doesn’t seem like it’s going to be a factor.

It’s far too early and totally inappropriate, but I’ll say it before another inmate does - perhaps “Wipe Out” by the Surfaris would be best to tap out on the side of that hull. . . . .

 

[Dr Rob]

In all honesty, what do you think the chances are that anyone aboard the sub actually knows Morse Code? 250k to go down in a sub...not easily afforded by most I'd think.

If it wasn't on a tether, there are a multitude of issues that could have arisen. Battery failure, drive malfunction and life support...even a faulty regulator. Even if structurally sound, the points of failure are numerous.

A lithium battery fire on that thing would be serious. I imagine that and the oxygen in that thing it would be instantaneous.

 

[pronstar]

Mental anguish and sheer panic can cause people to do very harmful things.

If someone (or several people) completely flips-out inside that thing, some hard decisions would have to be made assuming anyone still has their sanity.

 

[Taboma]

I wonder why there’s not a tether on it? I realize the short answer is length. But if you had a 1” line attached would you be able to raise it? Assuming the “splices” are rated higher than the rope/cable.

I'm sure you've fished, even light monofilament line has enough resistance to be pushed around by the waves or current. Now imagine a tether of the diameter sufficient to lift that sub and the weight of itself and how much 13,000' of it is going to be affected by ocean currents ?

All to familiar with 100lb and Tuna .

But even if they only ran a “small” line just so that a robot sub had a path to follow down.

I’m just at a loss on how you take people that far below with no secondary safety measures. Let’s say you do find them on the bottom, then what? Only thing that can go get them is a drone sub right? And maybe it hooks this imaginary cable we are talking about.

should have named the sub 50/50 lol

Seems like all their backup cards are several redundant systems that are supposed to bring it to the surface. Like you, I'd think they'd have some kind of small robotic submersible on the mother ship to possibly follow them or at least be able to locate and cut them free perhaps ??

 

[Bpracing1127]

Its twice the depth of the grand canyon and a bazillion psi and dark with current. After an hour and half decent who knows where it is, gps doesn't work under water

On many of the subs previous trips it failed to even relocate the Titanic.

It sure does. I know cuz we make it for the subs we build. Plus radio communication works too now. Cutting edge stuff really.

This is for navy sun depths not sure about these extreme depths

[stephenkatsea]

Morse Code SOS. Maybe known by many, but it’s worthy of mentioning here. SOS is simply 3 shorts followed by 3 longs. This can be performed in many ways, hull taps, flash light, head lights, horn honks, timely keying a radio microphone etc. They all are meant to let others know you need help.

 

[stephenkatsea]

Prior to my retirement, 10 yrs ago, underwater coms were conducted via an “Aucoustic Data Link”. Voice coms were not usually possible. And definitely not for long distances. It was data only. Call it texting, if you want. It is low freq coms conducted via submerged hydrophones. The very best at it were/is the whales. Seriously. And we were/are learning from them. I do hope there’s been tremendous advancement in coms and gps capabilities. I’m only speaking of our abilities 10 yrs ago.

Interesting, but how deep do those subs go?

The sub supposedly has seven safety features that allow emergency surfacing, three of them automatic. That these contingencies didn't surface the sub, the obvious conclusion is that an implosion occurred.

This is the third time the sub was diving on the Titanic. Any weakness that was exacerbated by the first two trips could have caused a failure.

It has just come out that a safety engineer for the company was fired when he discovered the manufacturer of the viewing porthole would only certify it to 1330 meters, while the Titanic lies at 4000 meters. He has sued the company, alleging his protests caused his firing, and he was fired "ten minutes" after the protest.

 

[stephenkatsea]

There are 2 types of underwater, both UNMANNED drones - ROVs and AUVs. ROVs ( Remotely Operated Vehicles) are tethered. The operator is in contact with the vehicle and operates it via the tether. AUVs (Autonomous Underwater Vehicles) have no tether. They are pre programmed via installed software. Changes can be made, at times, at times, during operation. But, it depends on distances and water conditions.

Some of the comments here have me scratching my head. Hopefully they come out of it alive. After watching some specials about the Kursk a month ago it settles in that they are in a shitty situation, something to not really make fun of. Just like the Kursk they set off on an adventure/event expecting to return to the surface... shit happened and some suffered for awhile before dying a painful, scary, and hopeless death.

I think the jokes (rough, including my own) come from how “spit and glue” this sub was.

Obviously being a billionaire doesn’t make you an engineer but at 250k a seat I would hope the customers would accept a certain level of professionalism. The same people wouldn’t dare board a G7 that looked like a 1950s Cessna (nothing against older Cessnas).

And then you can say that the big money people didn’t know any better. And maybe they didn’t. But the guy cashing their $250k checks sure as shit did. Talking about camping world parts on a vehicle that is arguably pushing the limits of all “earthly travel” just shows the level of professionalism.

 

[havasujeeper]

You're correct. It is indeed a tragedy. I couldn't imagine their family's feelings, or whether they are alive or not. I, like many others, are quick with the "one liners" and jokes, but for many, this is how we cope with the tragedy of it all. My prayers sincerely go out to all, especially the five inside this tin can.

 

[Not Sure]

Maybe they need to try a different prop!

 

[boatpi]

These folks are r.I.p.

 

[Runs2rch]

These folks are r.I.p.

Most likely.

 

[C-Ya]

This submersible might be built on the cheap, but then again, the first astronauts went into space in vehicles built by the lowest bidder. Both scenarios lack a certain sense of security, right out of the gates. Lol

BBC Quote :

“What emergency measures does the sub have?”​

“A submersible vessel is different from a submarine. According to the National Oceanic and Atmospheric Administration, a submarine can launch itself into the ocean from a port independently, while a submersible has very limited power reserves so needs a mother ship that can launch it and recover it.”

I thought about that but thought more along the lines of a high jack and use the sub for some sort of an attack

Regardless of the outcome, it blows my mind that people would pay 250k let alone go for free to get in this thing and travel to the bottom of the ocean knowing that it was built with random parts from "Camping World" and "off the shelf" components being controlled by a game controller, the valves even marked with tape and a sharpie. In the video the builder was actually laughing at how the thing was slapped together. I mean, what could possibly go wrong?

Exactly, especially if I'm filthy rich, why would you take that risk!

 

[HST4ME]

I'mma going down to whatever depth in a windowless coffin because I'm a rich fucking idiot. Fuck them. Not a dollar or threat of a life of a rescuer should be spent.

 

[QC22]

That’s what I need: A self launching submarine!! Just show up with your cooler, “take me to the Titanic, bitch”, and boom! Maybe boom isn’t quite right.

On what? The fukin thing sinks and rises, it has no propulsion?

The submarine's pressure hull is a carbon fiber structure.

I'm gonna quote myself. Fatique failures are a well known phenomenon, and I based my earlier comment from knowledge of carbon fiber component fractures or failures due to repeated stresses in IndyCar.

This is the third time the sub was diving on the Titanic. Any weakness that was exacerbated by the first two trips could have caused a failure.

This is a quote from Clarence's link:

In January 2020, Rush gave an interview to GeekWire in which he admitted that the Titan’s hull “showed signs of cyclic fatigue.”

"Cyclic fatigue" being repeated dives in which damage occurred. To my knowledge it had only been to Titanic depth three previous times, twice on the wreck and once in the Bahamas.

The hull was supposedly repaired by aerospace companies that no doubt had autoclaves large enough to properly fuse the resin on the repairs. But carbon fiber's strength relies on an uninterrupted matrix embedded in resin. If the repairs were even a tiny bit incorrect, the pressure at depth would have found it.

The sub stopped communicating after an hour and forty five minutes, and would have descended about halfway to the wreck. The pressure at that depth would "only" have been about 2,750 PSI.

I went to a 5 day deal at MIT for tech leaders …..lol low man on the totem pole there.

Anyway, one of the guys in my study group was the Director at NASA for refurbishing the shuttles after they came back. He “owned it“ from landing to relaunch. He said they literally bought parts for 386 computers off eBay as it was the only place left to get certain parts for the shuttle.

 

[HST4ME]

You do not "fix" compromised carbon fiber.

 

[4Waters]

It's got something, a reporter that has been on it said top side relays what direction they need to go to find the Titanic once they reach the bottom. The interview is in this thread somewhere.

Now, my thought is really out there for sure but....

 

[rrrr]

The gamepad was simply a man-machine interface, or MMI. it sent simple decisions and rate changes to a microprocessor, and pretty much the only things controllable on the sub were lights, propulsion motors, and the method used to increase bouyancy and rise to the surface, probably by dropping some weights attached to the sub.

Game controllers undergo millions of cycles without failure at the hands of gamers, so I don't see the choice to use it for control of the submarine as a big deal or a risk. It's kind of silly to point to that as an example of shoddiness.

Operating at the pressures of 12,500' underwater is undoubtedly what caused the loss of the sub. Anyway, I think so.

 

[rrrr]

It can be repaired. We sent a tub back to Dallara in Italy after it was damaged in a crash. It was set back certified as new. Same with aircraft structures. It's done all the time.

But going around a race track isn't done 2½ miles under the surface of the ocean, and that's where the problem lies.
