Titanic tourist sub goes missing sparking search

I'm hoping I can contain myself and not post the memes I've been laughing at all day... yeah, I'm a terrible person.

JFYI, you're not alone

I posted some they were removed. I thought there were on topic. Maybe should have posted them in the meme thread instead lol

This isn’t the Pub.

Anyone cruising the internet can see your tasteless BS.

You’re lucky you didn’t get a thread ban, some have.

Missing Titan sub likely intact but out of power, says expert who designed deepest-diving submersible

Engineer Ron Allum says missing tourist sub unlikely to have suffered a ‘catastrophic implosion’ but partial flooding could be preventing it from resurfacing

Not sure if this guys understands how this works.
At depth, they can't be sitting in a 'half flooded hull'. If there is as much as a tiny pinhole, the inside of the hull would fill up even if the thing doesn't implode.

“It also means that if the occupants are sitting in a half-flooded pressure hull, that could also be catastrophic. They could become hypothermic. I don’t know how well the CO2 scrubber systems would work if they’re wet.”

So who pays for all the private commercial vessels roped in for the search and rescue effort? Surely it must be expensive with the fuel cost, energy, time and man-hours of private enterprises…

Depends on who called them. If Oceangate did, they will be on the hook. If the coast guard did, you and I.

I have not read this thread, however. I have a US Coast Guard submersible pilots' license (Only for a sub that goes to 300 feet deep). I say this because the submersibles I piloted, which carry 48 passengers and 3 crew had an emergency drop weight. This weight weighs 2-tons and when released made the sub buoyant and it would float to the surface.

This weight was mechanically released by the pilot or co-pilot from the cockpit and did not rely on electronics. It was a manually activated lever that if cycled a few times pushed a pin holding the weight and the weight dropped.

This weight was drop tested annually at the dock and was an requirement by the American Bureau of shipping and the USCG before she was certified to carry passengers. I am quite certain this Oceangate submersible is required to have the same thing.

The submersibles I piloted also had the capability for voice coms with the surface and we routinely talked back and forth to the surface support craft.

This is a journalist quoting an engineer, so we know how accurate that usually is. Plus this an engineer from the team that built the Deepsea Challenger, so I think he probably knows more about it than you or I do.

Those suits along with the simple $400 EPIRB I keep onboard could make the difference in any surface rescue scenario...

The lack of some form of EPIRB (can't find confirmation or not of whether the vessel has on anywhere) would be criminal negligence in my mind. If the sub ends up being found intact on the surface days (or weeks) later it would be unbelievably tragic.

I think the most likely scenarios are probably total hull integrity failure during initial descent (60%), the vessel either becoming entrapped or the drop-weight system failing (30%), or having surfaced after some sort of systems failure and lost at sea (10%).
