Jarmak posted:The Baltic in that region is like 50m deep, that's within recreational diving depth. 50m is a little beyond rec limits (recreational diving typically stops at 40m/130ft, per PADI/NAUI/SDI). The no-decompression limits at that depth get so short (according to those agencies) that it’s assumed to be a decompression dive if you’re beyond that. You’re probably looking at rebreathers and decompression procedures, if you want any amount of bottom time down there. The alternative is taking like 4 tanks down with you, one as a travel-gas, 2 for working at depth, and the last one as a bailout if something goes wrong on the others. Would make it harder to carry any other things (like explosives). Open-circuit deep dives are extremely gear-intensive, rebreathers make things more streamlined. Your larger point still stands, though: I know divers in the recreational world that have the gear to make a dive to that depth and return safely. A diver propulsion vehicle would extend their deployment/escape range as well, these are also available for civilians to pick up (I know a diving quarry that rents out big ones).

Grip it and rip it posted:That's exactly my point with respect to whether the US government had ever named the names of the individuals Snowden's leaks are supposed to have killed But its a lovely argument, you cant disprove the statement that snowdens leaks got spies killed because the government wont name their spies. Snowden released a lot of documents about spy programs and was responsible for shuttering the spy program in Afghanistan. You think the taliban are going to say "well, they shut the program down, better not look any further into it!"?? If you do, youre dumber than your argument.

Madurai posted:One of the persistent tribal lore stories on the CGN I served on was that there were explosive bolts that held on the upper parts of the superstructure, controlled by some means of mercury switches or gyros or something, that would cut the topworks of the ship off if the roll angle exceeded some predetermined amount, to keep the ship from capsizing. It was dramatic as hell and obviously bullshit, because any system like that would have accidentally fired at some point in the years of service, maintenance processes being what they are. I'm going to assume they served on a Virginia class (not the sub) Comedy option: they served on a Kirov

My understanding is that's not how the pigs work. They are pushed forward by the gas normally flowing in the pipes. Since the pipes weren't operational and there was no gas flow the pig wouldn't have gone anywhere.

That Works posted:If that's the case then why is visible gas bubbling up from underwater? The pipeline has to be pressurized with something even if its shutdown. So its filled with 1.1m3 per meter of pipeline thats in that segment. Thats a massive volume that will be filling with water and bubbling for a while. Like 230 million liters of whatever the purge gas was.

The pipeline was pressurized to 105 bar with methane.quote:Nord Stream 2's operator said pressure in the pipeline, which had contained some gas sealed inside despite never becoming operational, dropped from 105 to 7 bars overnight. That's over 100 atmospheres pressure. There's lots of methane to come out. The remaining 7 bar is just water pressure from being 50m underwater. Ed: google says 300 million m3 capacity in the pipeline. There *have* to be valves somewhere but if not, at 100 atmospheres, 30 billion cubic metres of methane in there at STP. gently caress. Ed2: at 105 bar, it's supercritical fluid to boot. Rust Martialis fucked around with this message at 22:17 on Sep 27, 2022 |

Fair enough, my thought process here was this is in the margin of error for people pushing safety rules (not outlandish for people blowing up an international pipeline). In reality I can't imagine you wouldn't use someone who isn't trained for technical diving, was mostly emphasizing the point that this isn't landing people on the moon.

Since the pipes weren't operational and there was no gas flow the pig wouldn't have gone anywhere. If youre going to blow the line anyway, its not inconceivable they pressurized the line with water. Close off anything upstream of the pig launcher, and just pump water into that s.o.b. or maybe they used pipeline inspection robbits to drag the payload there. Theres a lot of ways to skin this particular cat.
