Strap through that acrylic viewport hole. But they might have removed it for lifting.

My take is they mobilized all these folks anyway, might as well get the wreckage and bodies if possible. I'm sure the same people paying for the trillions in PPP loans are paying for this (you and me!)

Damage on that presumably carbon fiber or fiberglass piece.

And it looks like they've taped over a section with plastic shrink-wrap for some reason.

Makes sense. Essentially a RW training exercise.

Real question: The temp rise would have been in milliseconds along with 34F water entry being in milliseconds. I'm wondering if that's enough time/exposure to said temps to truly incinerate human composition? I mean, you can cross your finger through an open flame and not burn it due to lack of time exposure.

Pressure collapse of all our membranes and nonsense is assured; however, I'm not fully convinced of true incineration given the timeframe....but I could be totally off on the thought process here.


No. Heat transfer takes time.

Looks like the mechanical bay at the back of the sub.

So they got the two titanium end cap mating surfaces, the titanium dome, the machinery space, two bags of unknown parts and the fiberglass facade.

And after all that you got two people touching a suspended load.

Five countries are investigating so it'd make sense to recover what they can.

Will remnants of their clothes still remain or all gone?

That was probably already on there. CEO was using it to keep water out.

All of hose covered up parts….are they stained with human splatter? Don't get while some of the debris is under wraps.

I know it's morbid, but I would like to know what a presumed human remains consists of.

So the interior didn't reach sun-hot temperature, as we were told earlier?

Not sun hot. I've seen a couple of people run the numbers and come up with 3000 - 3200 F.

The adiabatic temperature rise could have definitely generated air temperatures in that order of magnitude, however, the mass of the air compressed doesn't contain enough energy to actually combust anything before the water contacted the individuals.

This is similar to how you can grab a piece of aluminum foil from the oven and not get burned. Even though the foil may be 400 degrees there isn't enough mass to store enough energy to burn your hands.

This thing was built like a Pringles can.

Theres too much mating surface area exposed to high pressure.

Any imperfection in that mating surface and you are going to have a problem.

I don't understand how the thing sealed.

Just looking at it as a layman, i'm surprised it worked as much as it did. I'm surprised the thing worked at all.
Stat Monitor Repairman

This thing had to be split every time to get people in and out of the sub.

When they put people in the sub they had to flange it back up and torque it down to some exact spec.

It seems like that would take a good hour or two of highly skilled people to do right.

And you are doing it on an open barge exposed to the wind and sea.

Theres no way you can torque down to exact specs if you are heaving with the sea and trying to ****around on a small barge like that.

It would be extremely difficult. And extremely dangerous for the people trying to do it.

I'm curious as to how they did it.

I hope the deck workers on that barge are paid what they are worth. That seems like an extremely dangerous job.

Clutch type wrench.

Sometimes there's a reason they don't do it that way.

And that s a hard lesson to learn.

When something seems easier or cheaper. And you think you've got a great idea. You've got to keep in mind that there's a good chance that there's 'a reason they don't do it that way.'

I wonder if theres a video of the people climbing in the sub and the deck workers sealing them up.

It's extremely difficult to work on the deck of a small barge like that.

I can't imagine doing the work it took to seal up the sub on that barge. And doing it absolutely perfectly every time. When wou are dealing with 6000 psi. Thats what it would take. I don't think you got any room for error.

Maybe they sealed them up on the support vessel and then launched the barge.

Who knows how they did it.

Seems like the slightest imperfection in that metal-to-metal mating surface and you are gonna have a problem.

Any sort of debris that gets on the mating surface and you are gonna have a problem.

If bolts not torqued down equally and you are gonna have a problem.

Mess around and damage threads you are gonna have problem.

You forget to torque something and you are gonna have a problem.

Seems like they closed it up and there wasn't much more to it.

I don't see how that setup was supposed to work for 6000psi. I don't see very many bolt holes in that end cap. I still don't understand how it was supposed to work.

Looks like they bolt them in while on the support vessel then launch the barge. End cap secured by 17 bolts.

CBS reporter in 2nd video above said there are 17 bolts, but they only tightened 16 of them, cause one wasn't really needed.

6000 psi and they leave a bolt loose. I believe this was on last years Titanic dive, but he didn't say for sure which dive they told him that on.

That looks like an old Tidewater vessel. You can see the light blue paint on the stern ramp.
Stat Monitor Repairman

That seems dangerous from the stand point that there's got to be a maximum sea state to recover that sub.

So if the sub is down for an extended period of time and resurfaces to a heightened sea state, the submersible could become unrecoverable and the people trapped inside. They might not be able to get it back on deck. They'd have to send people onto the barge to unbolt the end cap in an emergency situation.

I could see people getting trapped in the sub due to deteriorating weather on the surface.

Just launching and recovering the sub seems really dangerous. You'd have to really confident in your weather window. Seems like they'd have been better off chartering a vessel with a moon pool. some sort of dive support vessel specially designed for that.
Stat Monitor Repairman

Even in a very modest sea state you could have the stern of the support vessel come down on top of that barge causing it to capsize with the people trapped in the sub.

Or the stern of the support vessel could come down on top of the sub and damage it with the people inside.

Not to mention the possibility of puncturing the underside hull plating of the support vessel.

Launching and recovering that sub seems like a serious operation.

You know. From a layman's perspective and all.

I think the more they look into not just the subs construction but the entire process they are going to find that this guy (now dead) cut a lot of corners and was a good enough bull****ter to get people to believe he knew what he was doing. This entire barge contraption launch seems like a really really u safe way to launch a vessel ..

I don't know anything about how this little tin can works, so forgive me if this sounds like a dumb question.

How do they "tighten the bolts"? With a wrench? Because that's what I am envisioning.

And if they went to the trouble to tighten 16, why not just do the last one?

They used cordless drills in the videos. I would hope that they used a torque wrench in the final tightening....

The videos I have seen is using a torque wrench and hand tools
