New missing submersible thread...

[Tidewater]

Pretty good segment here with a 20 year Navy submariner giving his take.

Especially interesting at the 5 minute mark with Ocean Gate's CEO Stockton Rush discussing hiring practices......to EXCLUDE 50 year old white ex-military sub veterans.

Well, to his credit, it does seem like they are doing something new.

It's just not the same thing though as "Old dog...new tricks"....

I was at Walmart today picking up my new prescriptions and in line ahead of me was an older sailor. We chatted a bit about the missing submersible and one of the things he commented on was the fact they were launching out of Canada and that right there told you they were trying to circumvent regulations that were in place here in the US.

I don't know how much of that is true. But wouldn't surprise me.

Had he looked at the geography? 380 miles from St. Johns, 900 miles from Boston? Besides, my understanding was that these vessels are basically unregulated, so launching from the US wouldn't make any difference...

And apparently not doing it very well...

It goes without saying, I agree with you.

Not sure, Earle.

BTW...a guest tonight on News Nation who was in submarine service said that banging noise that was picked up in no way came from the submersible. His reasoning was no sounds were heard until more recovery ships arrived. He said it could have been for example someone banging on a stubborn oil filter they were trying to remove while doing maintenance on one of the ships.

He said the problem here is the ships in process of scanning in other areas all of a sudden are re-directed to where the banging came from. So a false alarm sorta.

Made a lot of sense to me.

Other than the whole regular 30 minute interval thing

Yes. 30 minute timed intervals, resuming the next day sounds more like a signal, assuming there was something to bang on other than the carbon fiber/titanium hull. The hatch looks to be steel, so that would work...

Modern sonar techs (especially with state-of-the-art gear) can detect any number of sounds regardless of frequency. The low frequency energy of something banging the inside of the chamber will resonate through the hull and dense water quite easily.

IOW, I think you might be surprised at how well carbon fiber can transmit energy, especially surrounded by dense water. Carbon fiber actually has many acoustical properties similar to wood:

Acoustic coefficient values, calculated from Eq. 6, are also given in Table 1. Generally, the wood specimens show higher values than the polymeric ones. Among the polymeric composites, only the carbon fiber-polyester composite possesses an acoustic coefficient value (238.56) approximately close to that of walnut and beach wood specimens.



The glass fiber-reinforced composites show an acoustic performance similar to what walnut wood does. The results also reveal that the carbon fiber-reinforced composite could be used as an improved tailored high performance alternative to be substituted with wood in making musical instruments showing exceptional acoustical properties.

The submersible coverage has been the perfect example of news media chasing eyeballs instead of trying to present real news to the people.

Interesting story? Absolutely.
Will it impact anyone (outside of family members) watching it? Nope.

We got the bubble-headed bleached-blonde, comes on at five
She can tell you 'bout the plane crash with a gleam in her eye
It's interesting when people die
Give us dirty laundry
Can we film the operation? Is the head dead yet?
You know, the boys in the newsroom got a running bet
Get the widow on the set!
We need dirty laundry

I should have thought about the acoustic properties of carbon fiber since I’ve been wanting a carbon fiber acoustic for a while now. You can play them in the rain. They make great travel guitars.

My wife won’t let me have any more guitars though so I’ll have to do without.

An interesting admission.
Mrs. Tidewater discourages me from buying any more books. In her view, I have enough.

And as we all know, the ONLY reason for regulations is to crush innovation and limit profits and because bureaucrats. What possibly could go wrong?

Wonder if there are any “50-year-old white guys” in the rescue effort?

Of course, I’m sure their efforts are wholly unimaginative.

Can you imagine if he had said, “We don’t hire women, minorities, or anyone under 30….they’re spoiled, emotionally unreliable, lazy, entitled and honestly not that smart.”

Sounds like the 61 year-old CEO's mind is as or more closed as the 50 year old people he thinks he shouldn't hire. Anyone can innovate given the right circumstances, regardless of their age and experience.

And you're far less likely to spend copious amounts of time and money reinventing the wheel if you have experience.

Yeah in the documentary I posted above they went with a titanium sphere for DSV Limiting Factor because it was tried and true design. Guess which sub has dove to the deepest point in all 5 oceans and which one probably just imploded due to hull stress.

Debris from OceanGate sub found 1,600 feet from Titanic after "catastrophic implosion," U.S. Coast Guard says

The U.S. Coast Guard said the sub experienced a "catastrophic loss of the pressure chamber," and confirmed that a debris field found on the sea floor was pieces of the missing sub.

Debris field discovered....

Titanic Five died instantly when craft had 'catastrophic implosion'

The search for the Titan, a 21ft submersible operated by OceanGate Expeditions, drew to a close when a remote sub found debris on the ocean floor.
