Collymore Posted 22 June 2023 Posted 22 June 2023 Presume the bodies would be crushed into a state that resembles the thickness of paper. Doubt there's much they can recover... 1

Jattdogg Posted 22 June 2023 Posted 22 June 2023 Bit of a sad story if this is the end. What a way to go. The irony of going down at the site of the titanic which appears to be the case based on the latest news. Hoping there is a miracle of course.

Sol thewall Bamba Posted 22 June 2023 Posted 22 June 2023 The favourable outcome for them frankly. Rather instantaneous than 5 days marooned on the bottom of the ocean. 1

Leeds Fox Posted 22 June 2023 Posted 22 June 2023 1 minute ago, yorkie1999 said: Sonar. I know sonar is a form of communication, but it doesn’t offer much more than aiding navigation or potentially being able to send a ping or distress signal (similar to an aircraft transponder/SSR). When I read that there had been a comms failure, I assumed it meant a duplex system to transfer data or voice comms.

It also sounds like it didn’t work very well in the past. This reminds me of book I once read once a guy called Donald crowhurst who built a boat for the round the world boat race which was full of things that either didn’t work or were just made up, like a navigation computer that didn’t have any electronics in it, basically a dreamer who convinced people that he knew what he was doing.

stripeyfox Posted 22 June 2023 Posted 22 June 2023 A rescue was always practically impossible if the craft had become stranded at depth. Of course they had to try and they might have been able to recover it - given enough time. An instantaneous death for the occupants is probably the kinder way to go. Very sad for all those concerned. 2
Legend_in_blue Posted 22 June 2023 Posted 22 June 2023 I found it odd the other day with one of the guys who's been down there on the TV going into detail about how he took his selfie with the Titanic in the background. Doesn't sit right with me that. Weird behaviour.

Yeah, it’s obvious that nothing was going to work with the vessel imploding. I wasn’t looking for information on why it had failed, just what type of system it was and what lines or comms they could’ve had available. All irrelevant now. I just wondered if the type of comms system that was used had been specified (in a very boring sense, it interested me due to my line of work). Sounded like the company were a proper s**t show.
Popular Post Zear0 Posted 22 June 2023 Popular Post Posted 22 June 2023 3 minutes ago, Unabomber said: So the thing just imploded? Why? My guess... Safe working loads are a very crude assumption for vessel integrity. When you commission a vessel, you subject it to a pressure test usually at 1.25 design pressure (usually higher than operating pressure). Even after proof testing objects to loads beyond what they see, they still fail due to fatigue loading and fatigue crack growth. Media have reported on a letter from a regulator expressing concerns. Firstly, there was no prototypes so this bloke was mucking about with design changes and then sending crews down. Secondly, the carbon fibre construction is frankly daft. Carbon fibre has strong uniaxial strength which, generally, makes it only strong in particular orientations. Assuming they had engaged brain and strengthened in the axial planes to negate hoop stress (think how sausages burst open), that would be good, but it would also mean it was weak for failure in other orientations. Basically if it was being pulled lengthwise (stuck) it wouldn't be particularly strong and could have failed that way. Carbon fibre is also absolute shit for inspecting for defects. Defects are everywhere so on metal vessels, you deploy ultrasonics to identify defects and see if they're growing as you operate. This isn't really possible on carbon fibre so there could have been a defect growing with each dive until it grew and then made the entire craft go pop. That's what I suspect happened. I don't know the exact method of construction, but if the above defects were growing through the titanium it could have arrested the crack causing a leak, killing the crew but not involving a sudden crush. What they were doing with that craft is criminal and the poor souls that man dragged into his deathtrap paid for it with their lives. 10

The Titanic I think you’ll find that everything we do regarding any form of transport has always been done by corner cutting and then learning from what went wrong and then putting regulations in place to stop it happening again. In a hundred years, people will be diving to the deepest parts of the oceans seeking thrills in complete safety. We only learn through failures and then eliminating them. 1

I'd imagine the sensitivity and the amount of equipment they had down there it would have been very noisy even on a quiet day. 1
Collymore Posted 22 June 2023 Posted 22 June 2023 Surely a cable connected from the surface that would give comms, air and also a tether is a sensible and fairly cost effective choice? Seems a crazy design.

Seems a crazy design. Whether that’s feasible or not, it would have made no difference to survival of the occupants on this occasion as the catastrophic failure was irrespective of air supply and comms it would have saved a lot of money on the rescue op though

Sadly, it's human nature to cut corners and not learn from the mistakes of the past. That will never change, particularly where money is involved. People forget pain too easily.
