Tourist submersible visting the Titanic is missing 101

they are talking about it needing to go to Newfoundland to then get choppered out.

Sounds like a logistics issue, tha navy/coast guard only wants to deal with so many different entities. Magellan is definitely the real deal, oceangate should consider having them on standby during their next tour.

 

[stevenal]

Carbon, titanium, and seawater form a galvanic cell leading to corrosion. Galvanic series. The time below water may be short, but I suspect when out of water it is on the deck of the transport vessel and subject to salt spray.

 

[SWComposites]

Nope. Carbon fiber composite structures for aircraft (including Navy aircraft that are exposed to a lot of salt spray) specifically use titanium for metal fittings to avoid corrosion.

 

[Alistair_Heaton]

if they are hearing noises its more likely its not a failure otherwise they would have be dead by now.

Its more likely now its survived this long to be hooked on something that means the ballast release escape option isn't working.

Hence the reason why they want a 4000m capable ROV with cutting arms down there instead of a 3000M certified one with no tools.... But the coastguard seem to be determined thats what its going to be.

from another engineer...

"Yeah I heard that too! The hull was carbon fiber, and there are reports that the Director of the corp was fired because he whistleblew the fact there were serious safety concerns over their craft.

The CEO was reportedly complaining about over-safe regulations, and how it was killing industry."

Following: CEO of OceanGate, the missing Titanic tourist submarine, says didn’t want to hire experienced “50 year old white guys” because they weren’t “inspirational.”

Five people, who each paid $250k, were on board the Titan submersible when it lost contact with its support ship during a dive to the Titanic wreckage site in the North Atlantic on Sunday.

Each of those passengers are now trapped at the bottom of the ocean. They are slowly running out of air by Thursday morning. Horrific.

"We can train anyone to operate the sub with a game controller", says the CEO.

Besides being discriminatory, this is where being woke can destroy lives.

A "50 year old white-guy ex-Navy submarine operator" who has proven experience, especially under emergency scenarious, just might have done a better job.

Employing someone younger with little to no experience, especially in emergency operations, over someone that has rigorous military training and can act calmly under duress was a huge mistake.

Did not even have a safety beacon

Former OceanGate director of Maine Operations, David Lochridge (one of those 50 year old white guys with experience), was fired by the CEO in 2018 for whistleblowing about safety concerns regarding the vessels unique carbon fibre hull design -- and the lack of a basic safety beacon for distress calls

The deepest known ocean rescue was performed by the South African Navy in 1983.

It was a submarine rescue mission, known as the SAS President Kruger incident, which took place at a depth of approximately 1500 meters.

However, it's worth mentioning that the rescue was not of human lives, but of the submarine itself.

The deepest successful rescue of humans from a submerged submarine was performed during the USS Squalus incident in 1939, where the submarine was 243 feet (about 74 meters) under water.

The wreck of the Titanic is located approximately 2.37 miles (3.81 kilometers) beneath the surface of the North Atlantic Ocean. This equates to about 12,415 feet or 3,784 meters deep.

This is significantly deeper than any known ocean rescue mission.

More just posted by Mr. Premo.... on LINKEDIN:

"In this case the CEO was actually piloting the submarine, with zero navy or formal sub career experience.

Stockton Rush is the founder and chief executive of OceanGate Expeditions, the company that operates the missing submersible. He was piloting the vehicle.

Mr. Rush is a descendant of two signers of the Declaration of Independence, Benjamin Rush and Richard Stockton

He obtained his BSE in Aerospace Engineering from Princeton University in 1984, and his MBA from the U.C. Berkeley Haas School of Business in 1989.

Rush is an experienced pilot.

Rush became the youngest jet transport rated pilot in the world when he obtained his DC-8 Type/Captain’s rating at the United Airlines Jet Training Institute in 1981 at the age of 19. He served as a DC-8 first officer during college summers,

Rush had ZERO naval or even commercial submarine experience prior to founding OceanGate.

The missing submersible that was on its way to view the wreckage from the Titanic relies on a number of "off-the-shelf parts" including a video game controller to steer it

CBS Sunday Morning correspondent David Pogue went on the OceanGate Titan in November for an assignment, and said it was like being in a "minivan without seats.""

Complete Stockton Quote:

“When I started business, one of the things you’ll find for other sub operators out there, they typically have people who are ex-military submariners and you’ll see a whole bunch of 50-year-old white guys. I wanted our team to be younger, to be inspirational,” Rush says in a recording, which is circulating on social media. “And I’m not gonna inspire a 16-year-old to go pursue marine technology, but a 25-year-old who’s a sub pilot or a platform operator or one of our techs can be inspirational. So we’ve really tried to get very intelligent, motivated younger individuals to get involved.”

Any comments out there ???... Sub pilots and platform operators are OBVIOUSLY more qualified than experienced naval engineers...

Any Comments from a "whole bunch of 50-year-old white guys." ....

It will be interesting to wait and see when (or if) we learn just what happened, and then make judgements about whether corporate culture, hubris, video game controllers or what else may have contributed to the accident.

[thebard3]

The Coast Guard Captain who gave the daily briefing today said he was not aware of the claims of sounds 'every 30 minutes', only unidentified noises that are still being evaluated. I saw a report somewhere today that Morse code SOS was detected. I'm really not believing much that I hear right now as pretty much everything is just speculation. rumor, and unsubstantiated allegations.

I suspect that any of the waivers the occupants signed aren't worth the 'powder to blow them to...". Too many holes and the sub company looks to be real flakey...

[Alistair_Heaton]

if they are still banging on things it means that the thing hasn't imploded. Even a water leak with more than 300 bar delta P will have driven the N2 well into nitrogen narcosis levels and oxygen PP over over 1.6 bar would have killed them anyway.

I suspect they have it hooked on some wreckage.

 

[Murph 9000]

Yeah, if the internal pressure exceeds around 5 to 10 bar, the air becomes toxic without an advanced gas scrubbing and mixing system. This vessel certainly does not have the necessary equipment to maintain a safe breathable environment under significant internal pressure, as it's designed to remain at somewhere close to 1 bar. Beyond 5 bar is going to be troublesome with prolonged exposure, and beyond 10 bar the normally safe gases will be rapidly toxic.

 

[Alistair_Heaton]

And total pressure over 3bar on normal air mix and steadily getting worse as it increases will have them utterly narcosis on nitrogen in the mix. they are way beyond the depth that helium narcosis starts.

 

[stevenal]

Nope. Carbon fiber composite structures for aircraft (including Navy aircraft that are exposed to a lot of salt spray) specifically use titanium for metal fittings to avoid corrosion.

Not quite the same pressures in an aircraft. Titanium is closer to carbon in potential than other metals, but there is still a difference in potential.
