Sub goes Missing
Re: Sub goes Missing
Might be difficult for families to sue the sub operator as it seems they signed detailed disclaimers warning that things could go wrong including death. Not sure how much certification was needed to allow passengers on board though.

Re: Sub goes Missing
So they've been officially out of oxygen for a few hours
Re: Sub goes Missing
The US coast guard said that they would be out of oxygen at 12:08pm (uk time) That's pretty specific.
According to one expert it all depends on the temperature, the co2 content of the air and the oxygen consumption of the individuals. I know when I go diving I use almost twice as much as the mrs does for the same dive.
The oxygen doesn't just run out and then everyone dies, the oxygen content of the air will start to drop and the co2 will start to rise. Some people have better tolerance than others to co2 so they could survive slightly longer.
The water temperature at that depth is close to 0. If it's really cold inside then they may be suffering with hypothermia in which case their bodies will shut down and they may lose consciousness which in turn would mean their oxygen consumption will drop. It's a dreadful scenario to be stuck in that little tube with no means of escape, in some ways it would be a blessing if they've become unconscious because of the cold. That could also give rescuers a few more hours to find them.
If they find it and they can bring it to the surface the journey back up is likely to take 2 hours or more. The only scenario I can imagine that would mean they are still alive is if Titan got stuck on something and couldn't come back up even after dropping its ballast or inflating its balloons.
If that's the case the only solution is going to be assistance from the Victor 6000.

I think the sub imploding pretty much when they lost contact is the most plausible scenario.Rick_Muller wrote: ↑Thu Jun 22, 2023 4:57 pmBreaking news on BBC - debris found in sub search area.

I hope that this catastrophe at least reinforces the need for proper procedure in Enginnering… Cutting corners and trying to be cost effective to the detriment of everything else never works out (see Boeing 737-Max fiasco for another example)
Some of the comments I’ve read from the CEO Stockton Rush are quiet frankly disgusting - and I feel massively undermined the process behind Engineering… an attitude that I see with a lot of people in positions of power (normally coming from non-technical backgrounds)
Flaunting standards and skirting around legislation via waiver is beyond madness, if honest.
Some real poetic irony here regarding the fact that he sacked and then tried to sue one of the design engineers/consultants for expressing concern about the design of the Sub.
It’s a tragedy of course and I sympathise with people on board…
I also hope that we understand the importance of collaborative ‘government’ organisations that have spearheaded the rescue effort (you know, with tax payers/collective money) instead of constantly undermining them to praise the private sector instead ….
One of the guests Piers Morgan had on was seriously hellbent on crapping on gov agencies and praising Ocean Gate for being ‘pioneers’ & ‘daring to do what people say cannot be done’ - again, the irony not lost on me whatsoever

Re: Sub goes Missing
Going on the (admittedly grisly) assumption that they weren't going to make it whatever happened, the sight of debris would at least initially suggest it was an implosion of the submarine, therefore a pretty quick process, rather than the horrifying prospect of slowly suffocating due to lack of oxygen. I mean, neither scenario is great, but then it seems like an unbelievably risky endeavour for which they've unfortunately paid the ultimate price.
Re: Sub goes Missing
I'm still amazed that there wasn't anything that stayed on the surface while the submersible went down - such as a second submersible, that could immediately go down to rescue if anything went wrong.

The complete lack of a rescue plan smacks of amateurs playing around in dangerous territory.
The other thing is 34 successful previous trips can lead to complacency .
Hopefully the sub will be recovered and an investigation will find what went wrong.
Hopefully people will not be so fast to jump in an experimental craft in the future.
RIP those on board.

Re: Sub goes Missing
It seems strange that there is now a possibility that the submarine broke up, unless it happened later on.
Were they not confident that the sounds heard were likely from the sub because they were happening at regular intervals?
I suppose there’s the possibility that being down for so long, the pressure could have become too much.
Whatever the cause, an awful event.

Re: Sub goes Missing
I was reading a salvage expert yesterday who was saying once they find the sub it may still be easier to rescue someone stuck on the moon as at the depth they could be. Another expert suggesting there may be secret military kit that could be employed… but nothing in standard salvage operations is designed for such depth. Another commentator pointing out all the coverage because the passengers were billionaires and asking how much resource is being put into finding the hundreds missing off Greece. It sounds like the attitude was changing last night from a rescue to a salvage operation in order to tighten up submarine standards.Lowbankclaret wrote: ↑Thu Jun 22, 2023 5:50 pmThe complete lack of a rescue plan smacks of amateurs playing around in dangerous territory.

Though the time line for air supply is only estimated and they may have more air than is generally thought (or less).

There's bit lots of uncertainty and inconsistency about the source and regularity of the noise. I guess it will transpire that it imploded early on. I've been fascinated by this incident.

The sounds were spurious apparently. Was obviously an implosion as they have found the debris. It would’ve happened immediately when they lost contact.DCWat wrote: ↑Thu Jun 22, 2023 6:08 pmIt seems strange that there is now a possibility that the submarine broke up, unless it happened later on.

Having worked on Aircraft for 26 years I find it incredible that these companies are allowed to stray away from the regulatory boards. Watching the news at the moment and a man who is friends of two of the passengers is talking. He mentioned Stockton Rush felt that the regulators were holding them back. Scary! I guess it was an accident waiting to happen.

Debris found. Landing frame and rear cover. The only good news from that is that it would have been quick.
Re: Sub goes Missing
Im not sure why - it’s not as if we aren’t fed news of awful events throughout the world on a regular basis - but this story has for reasons I don’t know, been one that’s played on my mind every day.
As awful as it sounds, I do hope that it did implode at the outset. Better to go quickly with little, if any awareness, than to sit there for days waiting for the inevitable.

Re: Sub goes Missing
This has been a fascinating news story of mankind’s need and want for adventure, technology and engineering (good and awful), of hope, and of the natural wonders of the world, showing that they are never to be abused.
The vastness of the ocean and the peril that it poses…. I’m still not quite sure that the human race can comprehend its true scale, just like that of outer space, yet so much closer to home!
The one thing that brings comfort now, several days on, is that it’s looking like death will have occurred instantly on the fact that the five people on board will unlikely have suffered at all, is a good thing. The thought of them having panicked four days and died slowly, one-by-one, is tough to comprehend.
Let’s hope that we learn a lot from this experience.

Re: Sub goes Missing
111 in cricket is an unlucky score and 111 years post the Titanic sinking another five victims-very sad. From the outset once there were problems reading the news pieces there was no way they could have been rescued. Assuming it imploded soon after communication was lost better to die that way than spending four days waiting to die.

Re: Sub goes Missing
As much as the story may represent man’s quest for adventure and knowledge it is only billionaires that can afford to pay for such excursions, to the very depths of the ocean floor and flights into space. If this mode of transport was more accessible to others I am sure that it would have been far better regulated to ensure that all submersibles meet strict safety criteria. When we learn that the pressure on the craft would have been the equivalent of the weight of the Eiffel Tower then it puts into context the risk of the submersible imploding.

Re: Sub goes Missing
As I understand it this machine descended and ascended thirty times without imploding so it must have had something going for it. Clearly an issue occurred and perhaps there are maintenance records that might give a clue. Whether the authorities are able to recover any relevant debris hasn't been mentioned yet.
Remember the experiment in school physics to show atmospheric pressure:
https://www.youtube.com/watch?v=j0TQxYemrgg
That's one Atmosphere of pressure. The sea pressure at Titanic's depth is apparently around 380 Atmospheres.
A passenger aircraft has a pressurised cabin (the pressure pushing outwards) so when flying at 35,000 feet were the pressure is less then one Atmosphere it doesn't explode. The same presumably applies to the Space Shuttle.
The conditions in the abyss are way beyond every day understanding.

Re: Sub goes Missing
Titanic director James Cameron believes authorities knew all along about implosion and location of the sub, just heard a slightly longer version of this interview on the radio where he said many organisations had picked the sound up of an implosion at the time.

Re: Sub goes Missing
I thought pressurised cabins in aircraft were about getting enough oxygen to breath, the air outside being significantly thinner/less pressure and therefore containing less oxygen.Hipper wrote: ↑Fri Jun 23, 2023 9:16 amAs I understand it this machine descended and ascended thirty times without imploding so it must have had something going for it.

Re: Sub goes Missing
I think aircraft are pressurised to atmospheric pressure at 10000 feet an altitude where you can fly without needing additional oxygen.

Or you could rent a private sub and go and look at what's left of the migrant boat that sank in the Med. Is that OK?
And if it was OK to send fee paying passengers down to the Titanic last week, then presumably it's OK next week to do the same and take in the new debris field?
Re: Sub goes Missing
That’s just the way the media has always worked. Case in point, three people are murdered in the streets of Nottingham gets wall to wall coverage because of the drama and potential links to terrorism. A couple of days later four people found stabbed to death in a flat in London and it barely gets a mention. Both tragic events but one makes for ‘better’ news coverage.

They are indeed hence the reason passengers only have a few minutes of oxygen supply in the drop down masks.
If there's an issue with depressurisation, the Captain will get you down from the cruising altitude to under 10,000 very quickly..

Re: Sub goes Missing
They are (both for oxygen and temperature) but they still have to be structurally able to cope with this including allowances for movement of the structure and metal fatigue problems. In the early days of jet passenger planes it was an issue, notably the De Havilland Comet.
https://www.bbc.com/future/article/2014 ... ane-design
In WW2 bomber crew flew at around 20,000 feet but didn't have a pressurised cabin. Instead they wore oxygen masks above 10,000 feet and froze their nuts off. How on earth the Zeppelins of WW1 and the fighters that went up to shoot them down coped I don't know.
