Titanic tourist sub goes missing

Instant death. Milliseconds. I don't know if crushed is the right way to describe their final moment though.
Nope. Headed straight to Chapter 7. Liquidation.
Might as well have the filing ready.
I wonder if an ex-employee would put this job on their resume?
Chief engineer on the Oceangate sub that imploded.
Dress up the job description a little better than I did of course
I'm no engineer, but I'm aware that properly designed machines or machine parts come with safety factors. Wire cable, slings, shackles, pins, bolts, etc. used for cranes are a good example. They all come tagged with a stated capacity. This capacity is well under what they're actually capable of handling. Safety is thus factored in. The Titan was designed to be able to go down 13,000 feet to the Titanic. Yet, it failed to do this. Structurally failed. I don't see how it's possible to see this accident as anything other than foolish trust placed on an improper design.
It leaves chunks. There was a reddit thread yesterday with photos from a explosive decompression. I'm not happy I saw the results.
It had already went to the titanic and back three times prior to this expedition.
That doesn't mean the design wasn't faulty or that it was properly maintained.
If you want to parse words, he said it failed to go down 13,000 feet to the Titanic, not that it failed to go down 13,000 feet to the Titanic every time. I read his post to express the thought that such an apparatus should have a robust design capable of its intended repeated use, and that parts with an expired anticipated useful life would be replaced. It would appear that in this case, the hull needed to replaced because the carbon fibers were weakened and ruptured. You don't get to bat 750 with submarine hulls.
When a submarine hull collapses, it moves inward at about 1,500 miles per hour - that’s 2,200 feet per second. A modern nuclear submarine’s hull radius is about 20 feet. So the time required for complete collapse is 20 / 2,200 seconds = about 1 millisecond.
A human brain responds instinctually to stimulus at about 25 milliseconds. Human rational response (sense→reason→act) is at best 150 milliseconds.
The air inside a sub has a fairly high concentration of hydrocarbon vapors. When the hull collapses it behaves like a very large piston on a very large Diesel engine. The air auto-ignites and an explosion follows the initial rapid implosion. Large blobs of fat (that would be humans) incinerate and are turned to ash and dust quicker than you can blink your eye.
Sounds gruesome but as a submariner I always wished for a quick hull-collapse death over a lengthy one like some of the crew on Kursk endured.
There are several sources of hydrocarbons inside a sub. Hydraulic oil, diesel oil from the auxiliary Diesel engine, kitchen oils, grease, rubber, plastics, etc. This stuff sublimes to make its way into the sub’s atmosphere. It permeates the crew’s clothing.
What happens to the human body when a submarine implodes?
Answer (1 of 4): In short, the body is reduced to fish food, since not much of the hull remains unless it’s a section already flooded. Of course that surmises that the entire boat is affected; in fact, (to an extent) human remains were found during the highly classified Project Azorian, which rai...
I get that, but going to the Titanic shouldn't have been anything extraordinary for the Titan had it been designed properly. The implosion proves that no safety factor existed for it whatsoever. It failed within its stated specs! That's something that can't ever happen. And doesn't with proper engineering.
Stating the obvious, but there needs to be an investigation into the silencing of the whistleblowers, and its previously reported problems which were not publicly disclosed or apparently vetted.
Yet, it may not have been engineered to undergo cyclic stresses to that level.
Cyclic testing is a thing
NDE is a thing.
Did they do either with their "composite vessel"?
Yes, if the merry-go-round was located under a 6,000 pound anvil with a loose bolt holding it above...
I experience an explosive decompression every Thursday morning after "wings Wednesday."
My version of heaven has the billionaires who inherited their wealth explaining that this what they did with it.
I heard that they only did the initial stress test where it applied that level of pressure to the vessel for an extended period of time and it did pass. However, as you mentioned, they did not do any testing for repeated exposures. Since carbon fiber had never been used to build this kind of vessel, there was no real world indicator of how many repeated exposures it could handle. Well, now we know.
I fear we’ll never know now what was making those tapping sounds.
Not saying these guys deserved this outcome, but ..........
Unless they were hoping to somehow bring back souvenirs, why would one want to do what that they did? Other than proving that $250K means absolutely nothing to you, why would you want to be tightly packed into a sardine can - that could go 'boom!' in the right conditions - to go look at something that looks just as good on TV through underwater cameras in hi-def??
Why? Just ... why?!

The oceans are extremely noisy with all natures of sound. Given the Titan was destroyed by a hull failure, I don't believe the tapping sounds that were detected well after the sub went missing were of any relevance.
It’s like waiting your whole damn life to take that underwater journey, and while the sub implodes you think “well isn’t this nice”, isn’t it ironic, don’t ya think?
ITS LIKE RAIIAIIAIAAIIAIAINANNNNNNNNN ON YOUR WEDDING DAY!!!!!!!!!!!
