Sometimes during our monthly SSMG clean and inspect, when we would get cycled twice with 6 hours of maintenance after watch in a row, I would shut my eyes with my arm deep in the machine and pass out for a moment or two. I'd also skip my after watch meal to sleep for 20 minutes in my rack prior to cleanup because of how tired I was.

Skipping food for more sleep is a true Navy tradition.

I'm not the type to nod off easily, but I have stood between the condensers so I would hit my head when I passed out on my feet when I was standing port and stbd ERLL, with 9 hours on, 12 hours of ORSE workup drills, and the last 6 hours back on watch, with a continually worsening hernia. I also used to make sure that guys who spent their offgoing and oncoming doing maintenance snuck off to the rack before the coner chiefs came back aft for afterwatch when I stood EWS.

I always made an effort to be in the front of the chow line at lunch. Ten minutes eating, fifty minutes rack time.

The compression of the air within the submarine is an adiabatic event, similar to a diesel engine, and internal temperature of the submarine very quickly reaches temperatures at or above 1,000 degrees. These events occur faster than a person could "experience" them, so while there would likely be some very fraught last minutes as they attempt to save the ship, no one would be aware of the final event.

I'm aware. This is a better outcome than coming to rest on a shallow part of the ocean and running out of O2. Still sucks that it happened.

I became an ASTAC so I could hunt subs, because subs scare the poo poo out me. Both because of what they can do and also in general. gently caress submarines.

We've come a long way since that kinda thing - you couldn't do anything like that to any hyperbaric equipment the Navy operates if you tried. Speaking of... I'm about to run a recompression chamber on a carrier deployment, any tips besides "bring a hard drive with every piece of media you can get your hands on?"

Yeah, I am sure that we have numerous interlocks in place that would prevent the wrong order of operations now. Hard to imagine they did not include any on that vessel.

The environmental control system on the F/A-18 has had a bit of a thing for trying to kill pilots lately, and one of the ways involves massive pressure fluctuations. Treatment for that involves getting put in a hyperbaric chamber for a while to alleviate decompression effects.

We treat it the same way we would with normal decompression sickness, but symptoms tend to present differently in altitude induced dcs - a lot more brain involvement and less spine for severe cases. Most common symptom is still simple joint pain, though Plus, we can dive ourselves or the EOD det if we need to (or even just want to). You gotta have a NAVSEA approved chamber within 8 hrs to do any dives (sometimes closer depending on your table and schedule), and getting foreign chambers approved is a hassle.

FrozenVent posted:The gently caress does a carrier need with a decompression chamber? A carrier isn't just a platform for launching planes, but is a mobile logistics hub for all sorts of stuff including medical. Decompression tanks are probably pretty useful, especially for SEALS/EOD. An available decompression chamber would reduce risk to divers if they have to bug out of a dive or suffer an equipment casualty, but may not be available off the coast of hostile nation fushia. If you're going to pay for the weight somewhere in the strike group, the nuclear powered super vessel probably the most economic place to put it.

Well I’m all done out here. Last day on the ship and awards/going away finished. Managed to get a Nam, a ridiculously high eval and snagged the EP. Still won’t be home until a year a day after I left due to ROM. gently caress.

Flying out I ran into a 40 year civmar employee on the USS Hershel Woody Williams. https://en.m.wikipedia.org/wiki/USS_Hershel_%22Woody%22_Williams Had high praise. Said it was single worse ship he’s ever been on because they don’t keep the tanks full so it rides really high, Top heavy from the deck bolted on and rolled like a drunk pig. He literally retired instead of being stuck on the ship one day longer than his bare minimum. It’s ugly as sin too but that’s not really relevant.

     Injector blew fuel onto the exhaust while on MDO. Heard they attempted entry before dumping CO2. Most of the automation is gone. Manulani also had a dg fire same day.

Henry did the same thing. Fire in a steel box is going to melt any wiring/cable above it and warp the steel. Think she is under tow, probably headed back to LA/LB.
