Read this recently; posting it here purely out of scientific and academic curiosity.

A US Navy salvage system has arrived in St. John’s, Newfoundland, a Navy official said Wednesday, as crews prepare it for mobilization to the site of the ongoing search for a missing submersible.

The Flyaway Deep Ocean Salvage System (FADOSS) is capable of retrieving objects or vessels off the bottom of the ocean floor up to a depth of 20,000 feet, more than enough to reach the wreckage of the Titanic.

But before the FADOSS system can be used, it must be welded to the deck of a ship, a process which can take a full day, the official said.

The FADOSS was most recently used to recover a F/A-18 Super Hornet fighter jet from the Mediterranean Sea last July. Its deepest recovery to date was at 19,075 feet, the Navy official said.

This might not be common knowledge but there has been a new type of hobby that some have started indulging in of late: wreckage tourism. Essentially, you dive to wreckages (typically of ships from the World Wars) on the ocean floor.

This incident is going to bring tremendous focus on this unregulated activity, and rightfully so.

Thank you for pointing out the truth of the emperor's new clothes. Western vs Asian + super rich vs the super poor and of course the vicarious pleasure of a reality TV sort of experience. There is so much of unfairness in our world where we worship Mammon, the Greek God of wealth while ignoring the suffering of the needy. 5.4 million children die of child mortality each year. 24 million women live with complete or severe blindness across the world, 1000 million children do not get enough to eat in a day but the billionaires of our world, by and large, are not interested in using their wealth for these real issues. Frankly, I did not want to say it so openly on the forum but these are super-duper rich who consciously chose a seriously life threatening adventure and now the US, Canadian and French tax payers are funding this rescue attempt!

I would not ride in that thing even if THEY paid me 250k dollars.

But one doubt. That vessel is mentioned as a submersible, not a submarine. In which case it should have been connected to a mother ship by means of an umbilical cord or something. Then it would be a matter of just pulling it in. In this case it seems to have been not so connected and moving freely on it's own. Which makes it a small submarine and not a submersible craft.

I hope all of them make it out safely. After which the cost of rescue should be recovered from the said billionaires. Why should public money be spent for their foolish escapades? And the CEO/Pilot of the craft should be put away for fifty years.

A tragic and creepy co-incidence, if true



What Narayan Sir said earlier about the sub imploding might be the sad reality:

US Coast Guard says debris field has been discovered within the Titanic submersible search area

The US Coast Guard says a debris field was discovered by a remotely operated vehicle near the Titanic submersible search area, and authorities are “evaluating the information,” officials tweeted Thursday.

It is unclear if this debris field is connected to the missing submersible.

Very few people have expertise on these sort of craft, which are all effectively experimental craft to start with.

So apparently , the craft does not carry any insurance whatsoever. Everybody that wants to ride it is required to sign a very long and elaborate waiver.

It maybe true, but does seem seriously wrong.

Unregulated personal adventures like sailboats etc may be fine, but how is registering a company in a given country (US in this case?), and commencing risky, commercial operations without certification allowed, in US of all places?

Even so, why are the US maritime regulators and this company not being asked a few tough questions?

[Gansan]

^^ Even rides in an amusement park are subject to regulations and require certain certifications.

It is a different matter if only the employees of this company and their scientists alone take the rides, at least for a certain period of time and test it. But operating commercially and carrying fare paying passengers? That can not be swept under the carpet saying "scientific research" or "pushing the envelopes of human endeavour". That is pure nonsense.

RMS Titanic still claims 5 more lives 111 years after sinking.I think people should leave the big ship alone and let she rest in peace before becoming one with the sea, 1500 people died that night and they were all looking forward towards their new lives with many dreams and hopes shattered on that fateful voyage…not getting supernatural here instead of the facts but visiting such a place for amusement sometimes strikes karma…and these people in the submersible were rich they could have visited space instead or a good VR and a 8k Tv, they could have watched the videos of the remains of the ship like it was in real life.
Also there’s a news which someone shared on the forum too that stated that the wife of the submarine pilot was a descendant of a couple that died on the Titanic.The Titan had successfully went down and saw the Titanic multiple times, maybe this time they pushed its limits or maybe a mechanical failure, anyway the US coast guard has declared that the submersible imploded near the Titanic wreckage ...may god give strength to their family members and may the souls rest in peace.

The larger issue is that of safety in adventurous activity. When is it research for those willing to push the envelope, and when is it recreation? When do we allow such companies to take in unsuspecting passengers? In this case OceanGate had taken waivers that were 500 pages long. They have had submersibles explore many other areas for various purposes. If not the Titanic, they will explore other sunk treasures, caves, creatures, etc. As long as they are taking passengers there needs to be regulations, and regular tests.

Some diving enthusiast, declaring a tube driven with a game controller as safe to passengers, should have been stopped. I am sure this will be end of OceanGate expeditions in its current form.

Disclaimer: I am certainly not qualified about the technicality for any underwater activity, I am only asking for regulations framed by people who are experts in this domain.

Is it not possible they couldn't afford the tooling for a spherical hull? Cost-cutting seems to be a major consideration for this company.

You have given no argument in favour of a cylinder (in this case).

[Old_Salt]

Takes me back to the actual Titanic incident, The extended media coverage back then and the subsequent worldwide shock, due to the huge death toll, led to major improvements in maritime safety. The most prevalent one was the establishment of the International Convention for the Safety of Life at Sea (SOLAS) in 1914, which still governs maritime safety.

Probably need a XVth Chapter in Solas 2 now.

The US Navy had heard a sound that is consistent with an implosion, a few hours after the Titan had begun its dive -

Sounds like there was never really any hope.

Very sad news, I just hope that their last moment was swift and not the long drawn out scenario as imagined. Except for the poor 19 year old boy, they knew the risks.

My condolences to the families who must have been in agony.

May their souls rest in peace

And one of the passengers was a 19 year old boy. Did he give informed consent? Poor fellow.
