I Suffered Through Building Subnautica’s Deepest Ever Air Pipe

See behind the scene's by taking a look at my Patreon! ➡️ / aletho
Today my mission is to funnel the surfaces abundance of oxygen down to those in need at the primary containment facility using only Subnautica's Air Pipes. All I have to do is not drown or get eaten in the process, how hard can it be?

A few thoughts from an engineer -- no consulting fee required. 😁 You''d need a pump that could generate high pressure, to overcome the water pressure at the outlet end. At 1450 meters that would be about 2100 psi (assuming Earth-like conditions on 4546B). We have pumps that will do that, so Alterra certainly will. You'll need pressure-regulators at all the outlet points, so the work crew can breathe the air. No different from what a scuba diver puts in his mouth. You'd need some extra pump capacity to overcome the resistance of moving through that long pipe -- I'm not going to calculate that, but a second 2100-psi pump should be more than enough. I would start on the beach of Space-Gun Island and just follow the terrain all the way down, anchoring the pipe to the terrain with braces all the way. This would protect the pipe from collisions with Reefbacks and bending due to cumulative current forces. It would be easier for the work crews, too, having a solid surface to stand on at all times. Since the giant red moon would actually produce insane tidal fluctuations, it might be necessary to start at the TOP of Space-Gun Island -- without numbers I can't calculate, but the intake needs to be high enough to collect air even during high-tide, unless you want to build storage tanks and a control system to switch between supply sources depending on whether the inlet is under water. For long-term robustness, I'd go with the simple system, which means putting the inlet as high as it needs to be. You'll need more pump capacity because the pressure at the bottom will be higher at high tide. It might also be wise to run TWO complete pipe systems along different paths, so if one is damaged, the other will still carry air until repairs can be performed. We DO have leviathans and volcanic activity to worry about, after all. Building inside the containment facility is an unknown -- would the maintenance droids see the pipe as a foreign object and try to dismantle it? A defense system might be necessary. We also might need to change our attachment method, if the alien alloy can't be drilled for bolt holes. Would adhesive stick to the alloy? We might need to lay a concrete footing. Would having a pipe constantly there compromise the water-exclusion forcefield? Filling the facility with water won't harm our pipe, but it might not be great for the facility. This would be expensive, of course, but an insane man living alone in a titanium-rich environment with a universal fabricator has a different notion of economics than you and I do. Notice the assumption that we can't just build a FAR shorter pipe through the teleport gateway -- he's trying to keep busy, after all.

[@Cathowl]

This is the kind of brilliant comment I live for in fan communities. You do a serious breakdown of the problem but you also don't take it so seriously that you dismiss the whole idea as dumb. You commit to the bit and work out what it would actually take to do. I love it. :3

My guess is the pipes either have limited range of building in some way, perhaps a bubble projected from the pump or base attachment, and then once you hit the end of it it won't build that way, or the pipes after a certain length cause the game to get confused

[@kathydina3646]

I wonder if the pipes have an unintentional connection limit or build limit since the problem reared its head three times.

[@iAletho]

I did have a play with them after this and the issue seems to be present on the surface to if you take them into caves, so maybe it's something to do with how the game renders terrain? Not sure though!

[@SeedlingNL]

@@iAletho I suspect it has to do with horizontal distance from the floating air pump. The game is designed with verticality in mind, after all. Distant bases aren't simulated as detailed as the one you are near, and it's possible that the air pump is now located in the outer simulation shell, which is not accessible from the inner simulation shell you are in. It can't detect the pump, probably throws a hidden error, which is caught in the general exception handling for collisions and stuff, and your attempt to build is rejected.

[@midnight4685]

@@SeedlingNLHm, interesting idea, but at the same time, why would that stop him from building a vertical pipe but allow him to build a horizontal one? It seemed that down was the specific direction it didn’t want him to go.

Pro tip for both games when you use prawn suit: The drill arm plus the propulsion cannon arm is a good combo, The propulsion cannon arm being used to fling smaller creatures the hell away from you or bringing them in closer so you can absolutely grind them with the drill arm, its a pretty good offensive and defensive combo not forgetting that the 2 arms together are very useful in mining too

I am pretty sure the pipes have no limits but that there are invisible walls preventing pipes from passing for some reason. But, after experimenting at the jellyshroom cave, this wall isnt perfect and there are some spots you can squeeze a pipe through by gluing it as close as possible against the walls. There surely is a similar solution for the other caves.

I've been playing Subnautica for a while, and somehow I missed that there's a chasm leading directly from the surface to the lava zone.

I do know that you can go straight down with the C button, though, which is quite useful when piping oxygen or making vertical corridors on a base.

The challenge world itself is sat at 5 hours, although that doesn't include extra recording I did for story telling purposes and stuff like that. Overall the video took about 30 ish hours to make, everything included, I'd say about 10/15 hrs of that were direct recording (but it could also be more). I record most of my shots individually which makes things take even longer, every camera change is normally a new recording (except in this case the challenge footage). Hopefully that helps! :)

“The creatures living in the depths don’t need air” Actually they do, and since deep water tends to be fairly low in oxygen (due to plants needing sunlight and the deep sea having none of that) they probably got some benefit from the oxygen.
