How do i properly depressurize a ship?

[Ranayna]

I think because i am playing on Open Shift, i may have missed some tutorial. At least stuff that i have seen explained in Let's Plays have not been explained to me when i encountered them for the first time.

I have trouble understanding how to properly depressurize ships that have more than just a single room beyond the airlock.
Getting in through the airlock is simple. Finding the Regulator as well. But the last ship i tried, a Javelin, has a door leading to the outer area of the ship where all the cutpoints are.
The regulator is right next to that door.

If i use the regulator, the door closes, and the other room stays pressurized. If i break the door, the regulator becomes inactive. I tried blocking the door, but anything i put into the doorframe is pushed out once the door closes. I tried ripping the doorpanels off, but the door closes anyway. I assume that when i cut power, the regulator becomes inactive as well?
I tried to cut out the airfilter on the opposite side of the airlock, but the cutting beam is too wide, it cut something on the outer hull, leading to explosive decompression.
The effects of that decompression waries wildly: Sometimes it outright kills me, sometimes i get money subtracted, sometimes just nothing happens except that scary soundeffect.

What am i missing, or is depressurizing a ship properly without gambling with explosive decompression just not possible?

So generally I go in through the airlock and find a regulator then click it, then open all the airlocks I can while using the hud to find out if any rooms are still pressurized. Its just a problem of opening the airlocks then while maglocked to the wall, sure sometimes a few of them will toss some stuff around but its not usually a problem. I never kill the power until after its all depressurized and the hull pulled off.

It's about "volume" of air that's being "decompressed".

In a Jav, you're dealing with TWO areas, technically four. Fore (front), inner and outer, and after (inner and outer).

Generally speaking, even a room full of air is not going to affect the whole ship much, so much of the time, if there's nothing that'll fly around and mess up the pipes, you may as wel air out the air locks by lasering half of the door, or pop the cockpit (if you want to risk losing stuff from there) via the windshield.

But it's usually better to go inside, scout out the place, THEN plan your decompression.

Generally, you want to establish one area that won't be damaged much (usually as close to outer hull as you can, a single room with out much stuff that will spark, break, leak, and so on)), then open the door, which will force the next air area to rush in (and objects flying into your area), then repeat until all areas you want are depressurized.

If you have a door you MAY be able to use it as a shield so nothing will impact you directly (having a terminal hit you in the helmet is NOT conducive to survival)

You cut the door open and see how bad the damage is. If it's acceptable, continue, if not, abandon shift and choose a different ship.

a good way to depressurize with atmospheric regulators is to work from the inside out. find the innermost room and depressurize it with the regulator. (just find a room with a working one.). Then you'll cut the sealed door and depressurize the room next to you. It'll break the walls anyway so cut at an angle where it's as far away from you as you can get it. AND HIDE YOUR HEAD AMAP. Keep doing this room by room until you get to the airlocks and hull. the idea is you want to violently depressurize within the safety of the hull so that objects don't go careening into the void of space.

With NO functioning regulators, the opposite is better. Use big aimed cuts from the outside in. depressurizing things into the bay walls and not the void of space or the the furnace. I'd recommend doing depressurization first so that if it fails catastrophically, you can abandon shift and try again with minimal time loss.

I just went into a fully pressurized ship that I can only depressurize one room at a time for no reason. Went to largest space, I thought I'd cut/burn the door to one of the two smaller compartments and be able to depressurize the main AND the second space.

Nope. For some reason burning the door broke all air control units in the ship. Which sucks and is not fun.

Air pressure is one of the big areas that has been broken since forever and is still broken at launch. They've fixed a ton of stuff, but for whatever reason this ridiculous, unworkable atmosphere system remains. I have to assume it's a difficult issue in the game; they don't seem like lazy devs.

In a sane world you'd be able to disable doors (cut them, I mean) and then use an atmospheric regulator to pressurize/depressurize the connected areas. If you do that the regulators are inoperable. You also can't separate the power supplies. The doors opening and closing is always tied to regulator function - there's no way to make it work in a sensible fashion. Most larger ships (javelins and geckos) are impossible to depressurize completely using the regulators.

As a result you generally have to try to work around it. Always depressurize from the vacuum side rather than the pressurized side (Why does that matter? No idea, but it does. Things in the room, or the room itself, will often break if you cut the door from the pressurized side.) Clean up any loose material, then work your way from room to room depressurizing one at a time. Destroy half of the door with your stinger and then catch the other half with your grapple and hold it in the doorway to keep any debris somewhat contained. Hope that nothing particularly important explodes.

very carefully

The best 'advice' I have for this, and god knows if its actually accurate.. is to minimize the amount of volume you depressurize at once.

So I enter the ship, close every door I can, depressurize the room I'm in (or at least one with a working regulator), and then start opening doors (via door controls) to depressurize room/section by room/section.

On top of that; I gather any floating objects into the room I intend to depressurize via atmo control. This includes ALL OTHER atmo controls (broken or working) into the room I'll start with. The reason for gathering all the atmos together is they ALWAYS break off the wall and fly around on violent depressurization.

Lastly; I have found that it helps to 'start' in a room with the most computers or other expensive equipment, as it'll be the only room you depressurize 'safely'. This depends on doorway facings.. eg; if the violent depressurization coming from the door, aims directly at the computers, then those computers ARE NOT SAFE, and may get killed/blow up from flying objects coming through the doorway.

Good luck!

Just posted this in another thread

Best way to depressurize anything in this game, is to depressurize it *into* the ship. Because if one cabin is vacuum, it will eat the pressure of anything you open into it. Even if the pressurized area is larger.

Do this room by room, and you can *mostly* safely depressurize any ship. You just need a 'seed' vacuum.

Hang onto something and try to not do it to a room with a bunch of, say, fuel tanks, or biolabs. Try to pull those out first. Tuck 'em away into an already depressurized area, or finagle them out the airlock, because they *will* fly around the place and slam into stuff and explode.

there are 3 ways to depressurize room

1. Use Air Regulator, safest, but you many not find one in the room you want to depressurize
2. Force open door between pressurized and depressurized room, safe if you cleaned up loose or weak attached objects in the pressurized room first. Any air regulator, attached storage bin (usually in cockpit) or spared oxygen/fuel tank will be detached and flushed out, so make sure you moved them to a safe place first
3. Breach the hull/wall, only safe if you know where to breach. I never breach between rooms, will use method 2 if I can. I only use breach on exterior hull. It's better to find the biggest exterior hull plate without object behind it, then place the C4 on the edge of the plate to cause minimum damage. Sometimes the cut crack can depressurize the entire external space without even shattered the hull plate

More tips
Sometimes air regulators can be found in connected rooms, but if you use air regulator to depressurize one room, the other room will have to be opened with method 2, even there is another one air regulator there
But if you play with shift time limit, you can wait until a shift is almost over, then go to the deepest room and use the air regulator. Stay there and wait for shift over
Your next shift will spawn you at the hub so you can move the the next room with air regulator without forcing open the door of the depressurized room in last shift

I guess i was just too timid then :D
For the two Javelins i did after this post, i depressurized everything i could with regulators and airlocks, and then just opened the door between the inner and outer hull. This places me next to the door, not in the path of anything loose, and worked well now.

I also got the first proper mandatory training mission: For extracting Class 2 reactors. No idea why no other training missions came up.

If you click the skip training button when about to put the thumbprint for your contract, you get no trainings until you reach that point in the story. It skips the tutorial, tether, Cl1 reactor and pressure training. The CL2 training is part of the storyline, so you get it whatever.

[Ranayna]

Ooooh, i see. Yes, since my first attempt was on normal, i skipped training on the open shift run. I did not think the training would be more than the very first mission.

I just went through the tutorial in Standard Career mode. They specifically said there may be times when depressurizing using an atmospheric regulator isn't possible. The ship they used had a pressurized hull in addition to the interior. Unfortunately there was no door connecting the hull spaces to the interior of the ship, which is what they were probably referencing when they said it wasn't always possible. The method I used was to open all the interior doors and then use the atmospheric regulator to completely depressurize the interior. I cut off the drive nozzle and ejected the thruster using the panel. I cut out the roof and floor section from somewhere in the middle of the ship and removed almost everything from inside. Not knowing what to expect from the explosive decompression of the hull sections, I wanted to ensure all the valuable stuff was out. From there I cut the four points that connected the rear of the ship that originally contained the nozzle and thruster. The pressure in the hull section combined with the significant weight of the drive section limited the effect of the depressurization. It did eject it with enough force that I was then able to remove the fuel tanks that were connected to the rear section with plenty of clearance.

In hindsight, I probably could have left the interior pressurized, cut a small section of the interior ship wall so that the interior and hull spaces were connected and then depressurized the entire thing with the atmospheric regulator, which would then mean no explosive decompression. The problem with that is you don't know what's behind that wall that you're cutting. I'll probably try that next time though and see how it goes.

When it comes to controlled depressurisation, its best to do it one room at a time, that will prevent explosive decompression from destroying any panel walls.
