Tourist submarine exploring Titanic wreckage disappears in Atlantic Ocean

So.... If you were concerned on Oxygen, would you go ahead and Clinton the weakest one or would it be the biggest one, because he is using more O2??

I mean the bigger one would require more initial energy to take out, but would it be worth the exsertion>

You take out who is panicking the most. Scared people breathe faster and use more oxygen

note to self. don't go on any potentially life and death adventures with these 2. they have put a lot of thought into how they are going to out-survive me
 
That thing should have had a few of bags of rope on the outside with 8000 feet of 1/8 amsteel connected to something that floats, and some manual mechanism to release from inside (magnets? small release charge that can be set off with battery?). Obviously they should have been located on different sides of the sub.

Bobber floats up and has transponder gizmo, rescue vessel connects grappling hook with guide ring onto the 1/8 amsteel, then drops it down to the vessel. Vessel has mess of cable/rings at attachment point of 1/8 amsteel. grappling hook snags it and hoists it up.

2. Hypothermia - I doubt it. It would've probably already gotten them by now if they weren't properly dressed. Five people in that little sub are gonna create quite a bit of heat.

3. Floated to just under the surface - I doubt it. If the banging is them which authorities have pretty much confirmed then they didn't get baked in the sun. I would also think the aircraft overhead would've likely spotted them if they were just under the surface (then again, 100 feet deep is relatively speaking "just under the surface" in 12,000 feet of water). Suspended somewhere well above the ocean floor is possible but I would assume they would've drifted a pretty far distance by now and they've said the banging is "near" the Titanic for whatever that means. Either way, my bet is that they're on the bottom. They lost touch with the vessel on it's descent. If it was disabled there would be nothing to halt that descent.

4. Vessel ruptured - violent implosion was my initial bet but that's out if that banging sound is them banging on the hull.

5. Ran out of O2 - it hasn't happened yet if they're still banging but that's my current bet on how this goes.

6. Dehydration - lack of O2 will get them well before this.

7. Never recovered - that was my initial bet but if my current hunch is correct that they're on the seafloor near the dive site/Titanic then they'll probably locate it eventually.

Lots of stuff bangs, i'm not putting a lot of faith in that.. There are shipping containers, and all kind of trash, fish, debris, you name floating in the ocean.

With the vastness of the ocean, seeing an object so small, is a BIG ask. I'm not convinced they would see it, even if it was close to the top, especially because the orientation isn't guaranteed

You can only live 3 days without water. It was a short tour, I think that running out of water before air is very possible.




Personally, I think I read where they were 15 minutes from the titanic on last communication. I think they took a hard landing and bumped the bottom and it imploded.
They got the 3rd class ticket on the Titanic and got the full experience.

I doubt there's anything that bangs once every 30 minutes like clockwork though.

You can last quite a bit longer than 3 days if all you're doing is sitting aroundh.in a cool place.

Yeah, the ocean is vast but if it's near the surface they would have a pretty decent idea of where it is given current conditions, etc. It's not like they would be just randomly looking in the entire ocean. Surface conditions would play a significant factor if it was choppy though.

They can go all Bear Grylls or however you spell it and drink each other's pee, or suck on poops for water, etc. :flipoff2:
 
There’s a ridiculously long thread on arfcom where I read about this first, a lot of interesting info over there but a bunch of shit to wade through too.

As said, hull rupturing would be best case scenario. Crazy to think what that entails, the compressing air in front of the pressurized water would theoretically incinerate them before they drowned…like being diesel mist in a cylinder

Damn that would make make for an interesting chat in the afterlife
"How'd you end up here?"
"Well I was just minding my own business about 3km down in the ocean when I got crushed, incinerated, vaporized and frozen all at the same time. For .000001 of a second I thought I was going to drown but turns out that wasn't a problem at all"

Wouldn't it be something if they are stuck in the mud, powerless, in the shadow of the ship?

I just looked up Alvin the sub that found the Titanic. Its still kicking and has over 5000 dives under its belt. It's rated for something like 4 miles deep.

No idea where it's at currently but I doubt it can get back to the titanic in time.

www.whoi.edu

HOV Alvin - Woods Hole Oceanographic Institution

Since its launch in 1964, Alvin has taken more than 3,000 scientists, engineers, and observers to the deep sea, including visits to the Titanic and the discovery of hydrothermal vents.

There's nothing Alvin can do that any of the hundreds (or thousands) of work class ROV's can't do. I'd go as far to say that most any work class ROV is better suited to the task. The guys that fly these things do it every single day. Rigging and derigging heavy lifts is their job.

The hull of a sub slowly getting ready to implode maybe?:flipoff2:

What's interesting? Can you copy paste the article?
It wants people to create an account to read it. I assume you have one or got around it.
Click to expand...
I don't have an account I could just read it. Oddly enough that link did not take me to what I read/posted yesterday. But I scrolled and found it. Said they had 40 hours of air left. It was posted yesterday at 9:30 am so they might be still good today?

Holy fucking shit! One of those articles claims the sub has NO hard external attachment points. NONE! Who the fuck designs and builds something like that? If true, ROVs would have to net or belt it, I guess.

8000 feet isn’t doing them any good.

Yeah I was blown away by that. I guess they have an answer, but I thought most of these small subs/ROVs were hooked up to a crane and lifted onto/from the deck of the support ship as part of the standard operation. I wonder how they handle the logistics on this thing with no attachments

I have self rescuer training every quarter. They literally tell us that panicking uses more air, so stay calm and you'll live longer

I'm guessing how it's launched and recovered:

Betcha it has something to do with the cf hull.

Sorry, 15000 feet then.

Other than that, would something like what I mentioned be a viable option?

1/8 amsteel is 1/2 lbs/100 feet, so it would be 60 lbs of rope (but the rope floats....so.....).

Wouldn't take much to float that to surface, assuming it payed out ok like from a properly loaded stuff sack or bucket.

Ahh, so that platform submerges, the craft floats on or off, then it pumps the water out and floats itself? Then the craft just chills on that thing and gets towed around (or dragged onboard the support vessel?). I hadn't searched for pics, super interesting.

Good point. I think I read that front section (with the window) is titanium, but that's nowhere near the COG so attachment points up there would be pretty useless
