So, y’all remember that twitter profile “Shit My Dad Says”?
One of them was “when people start talking about sick size, don’t whip out a ruler; keep your mouth shut, stuff your crotch and keep your pants on.”
(Or something like that.)
The more they insist that their nukes … whelp. The more we think we should let them whip one out.
They’re being sued my 2 millionaire estates, a liability waiver is not enough, and I’m guessing Nargeolet (the explorer,) wasn’t exactly broke.
Usually liability waivers only apply to “reasonable “ risks that are known to both parties. “We might implode because we cheated out and aren’t doing the inspections and were using materials basic material science says we shouldn’t,” likely isn’t covered- it’s reasonable to assume they’re operating a safe sub when it blatantly wasn’t.
had me giggling in the first half, since I knew where it was going. Had me snorting by the end.
Grand Old Pricks
It really is basic engineering.
Like.
Probably not even 101. We’re talking about material selection…. And the properties aren’t exactly unknown and the necessary capabilities aren’t unknown.
The only think that was really unknown is how many dived it had. (CF can be fickle. It’s almost certain there were Minor defects. That’s just something you engineer around, sure, but you never know how close those defects are to becoming not-minor, and it really doesn’t take much. A single micro crack in the wrong place and… well, it probably happened fast enough that they didn’t even know.)
You, know that you’re supposed to replace the frame if you crash because of similar issues (specifically delaminating being hard to identify without destructive testing )
Just saying.
Though I do believe it’s never imploded….hehe.
That’s the problem with the carbon fiber.
Composites like that have a limited lifespan, and they’re very hard to model- there’s a lot of assumptions going into the modeling like “the fibers are all laid perfectly” and “the resin-to-fiber ratio is perfect” and similar. It’s also super hard to check for defects.
Normally, a lot of this is worked around by increasing the amount of CFC to provide a margin if error.
The problem is that you eat up that margin of error as defects expand under the cyclic stress of going down and coming back up.
Worse, they were not inspecting the pressure hull in a way that could detect the nano- and -micro-cracks so they could tell when it was time to take it out of service.
(That kind of inspection is ridiculously expensive. Like. Yeah.)
Well.
Normally this is avoided by using (very expensive) materials like titanium alloys that are “strong” enough to not fatigue after a few trips. (Strong isn’t quite the right word.
Or extremely expensive (to make) acrylic (PMMA,). It’s expensive to make because of some extremely exacting tolerances.
Incidentally, one of the reasons acrylic is used a lot is its transparency makes it super easy to see defects like cracks. (Literally you can see them with no special equipment.)
In any case while CF isn’t exactly cheap, it was less expensive than a titanium hull, or the acrylic bubble hull you see on the Triton subs; but the whole inspection thing got nixed because of greed.
Fun fact; the only reason this hearing is happening is because two of the passengers were rich. Normal people don’t get this dog and pony show.
Other fun fact: they signed liability waivers. Which makes this a very fun dog and pony show.
Greed. not “explorer passion”.
The risks weren’t unknown. People have been building submersibles capable of reaching that depth for quite some time, most of the people involved are very willing to share their lessons learned and give feedback. They were consulting with NASA and Boeing, both dropped it (I suspect because of a distinct unwillingness to heed their advice and warnings.).
OceanGate willfully ignored the risks, and the warnings, cut corners and found out. unfortunately four others found out, too. Though I only really feel bad for the kid.
It at least half will complain about the couch porn to Mike… or at least to the chat bit…
So it’s meant to annoy Mike even more.
And as far as I’m concerned… he can’t be punished enough.
I smell bullshit. Maybe unintentional… but yeah. No way he felt a shudder.
lets start with the communication system.
The Titan used an acoustic link system to communicate with the support ship. basically, it’s like Sonar. only the sonar has been modulated to carry data. at the best of times, it can carry HD video in a somewhat live stream. but that’s the best of times, and the Titan sub would have had to passed below the thermocline, which plays merry hell with sound. (military subs use it to hide, for example, because it significantly dampens their signature; or out right blocks it.)
this means their communications would have been spotty and sporadic, and basically limited to text updates. There’s no reason to believe the sub imploded at the time of the last transmission. How much time passed… I can’t say… though.
Secondly, it’s almost impossible for them to have felt the implosion. Maybe hydrophones picked up the implosion, but that’s about it. at more than a few thousand feet, it would have had to been a massive implosion to be felt on the surface. Sure locally, it was quite energetic, to say the least (things flashed into plasma under the adiabatic effects,)
Finally, they didn’t know what happened. It wasn’t until weeks later that the Navy came out saying they heard the implosion. If the support ship had felt the shudder, it would have been heard by it’s hydrophones, and they would have had a much easier time learning what happened.
Slow the redirect down, and show people ads for fake couch porn sites, too
Of course she did.
Because there’s no other way that trump would lose a debate, amirite?
(/s. Trump is the kind of idiot who makes morons look brilliant.)
I’m sure Ukraine could find a use. Maybe we tow it to a port of their choosing?
Where’s the Black Sea fleet hiding again?
I won a porterhouse from a steakhouse over Hilary losing.
I’d rather I hadn’t won. The bet was made in primary season, and that Hilary would get the nomination and lose the election. (There was a second part that said if Bernie won the nomination he’d be POTUS)
Pretty sure any overt act against a nato member is going to lead to all of nato jumping Russia.
That’s kinda the point of the alliance.
My guess? They used the pandemic as an excuse and noped out after interacting with them and getting that “hey these guys are going to kill some one.” Feeling.
Specifically because OceanGate was cheating out every way they could- including on validating their design with full scale pressure tests.
They also didn’t have any sort of inspection on the pressure hull- which there are very, very few materials that can take cyclic loading and not fatigue over time (even if it’s still only elastic deformation, most materials will fatigue and fail,).
Doing so under these extreme conditions? Yeah. It’ll fatigue and fail sooner rather than later.
“You want to use CF and not do testing for fatigue? And you want to put people inside this thing? NOPE!”
Which, Boeing also dropped them…
He couldn’t know that.
This is at least election interference. And attempted ballot theft.
Also interference in government processes.
Basically all medication has side effects.
Aspirin works by blocking production of cyclooxygenase, which, causes platelets not to produce thromboxane A2, effectively permanently rendering affected platelets useless.
COX also reduces productions of prostaglandins which mediates pain- basically, causing your nerves to pay attention to pain signals. (I’m sure some one who’s actually a doctor or nurse is swearing at me by now…) and also triggers more inflammation.
COX also increases production of PGE2 (another prostaglandin,) which is what triggers the fever response.
This is how most NSAIDs work, though they each have other side effects, that are different from the others.
I vote he get charged with the appropriate crime of stealing ballots and the drop box.
data brokerage is a multi-billion dollar industry with entire armies of lobyists from Google, Apple, Tesla (probably) and who knows who else.
just in case you were wondering why it’s not already done.
