The Ultimate Bad Example
Salt water is fatal to even saltwater fish you would have to so a suit swap about 210 days into the deco just due to corrosion but after that diving wet shouldn't be a problem.

A person couldn't dive the titanic....too cold, too much pressure.
Today I was trying to convince a coworker to try diving and mentioned to him I was diving a local wreck this weekend in 100ft. He jokingly mentioned he wanted to dive the Titanic and after both googling it we found it sits in 12,000ft depth. He also asked me what the world record was for the deepest dive and such and it got me thinking...assuming someone linked together several tanks from the surface all the way to the floor would it even be possible? And if so what would the deco time look like? And if its not possible what the deepest someone could go?
Are you sure you've got enough significant digits in those figures? You don't think you need higher precision?when we take in account the depths of decostops and so on that you need to carry 20411037.9 liters of air, if you dive with tanks that can hold 450 bars that means you need to have access to 45357 liters of compressed air
Yup, and water is fatal to all living beings, in a multitude of ways.Salt water is fatal to even saltwater fish
Impossible without a rigid container exposure system like a submarine. But as a thought experiment:
First off you need tanks that can hold greater pressure than 380 bars and a second stage capable to deliver 380 bars per breath,
that, in extension, means you uses 5*380 l air on each breath ( 1900 liter of air) on the bottom, that means ,when we take in account the depths of decostops and so on that you need to carry 20411037.9 liters of air, if you dive with tanks that can hold 450 bars that means you need to have access to 45357 liters of compressed air, lets say you dive this as a square profile with a bottom time of 5min, descend rate of 10 meter per min and an ascent rate of 9 meter per min, making the total dive time, excluding the insane deco stops, to a 13.45 hour dive. The decostops required for this theoretical dive is, according to v-planner, a total of 14856 hours ( 619 days ~ 1.7 years) whit a total of 980 deco stops, this is assuming you are using air, and nitrox 31 as deco gas. Of course you can't do this dive on air, to avoid oxygen toxicity syndrome, you need to dive with a mixture containing no more than 0.4% oxygen, and to avoid getting the king of all narc you need to have 0% nitrogen in your breathing gas leaving you whit a heliox mix of 0.4% o2 and 99.6% He, and my best guess is that breathing 99.6% He at 381 bars pressure opens up a whole new set of physiological effects. Of course this doesn't matter since, even if you can avoid oxtox and passing out from being super-narced, have OC equipment that can deliver the pressure needed and withstand the outer pressure of those depths, you will be killed either by the pressure of those depths or by one or more of the effects, from the long list of physiological effects you will encounter long before you even see the bottom, if you somehow survives all this, 1.7 years submerged in salt water is probably not good for you, even in a drysuit.
You forgot the rule of thirds.... You would be CRAZY :crazyeye: to try this dive without the extra gas.....
