I built a simple base with a base platform, a room, a solar panel, and a hatch. The base seems to be powered, but it is full of water. (the same water level as outside the base.) How do you fill it with air?

@Mark Ripley's answer has all the suggestions I was going to make.

It's possible this is still a bug: https://trello.com/c/xHLuc8cM/1443-23037-water-surface-effect-inside-your-base-when-built-on-sea-level


Even though another answer was the solution, I wanted to post since there is another possible reason why your base is full of water -- you have a breach. When you add onto your base, you should get a little message about hull integrity or strength or something. The lower that number is, the more likely you can get a rupture in your base, causing water to spill in. It fills up in relatively real time, so if you're gone for a while, the base could be completely full, or if it ruptures while you're there, you might see what looks like an inch of water or so on the floor. I keep a charged welder with me at all times for these cases, and it's happened several times so far.

    Just wanted to add, I believe it'll only spring a leak if the hull integrity is negative.

  • This is not the case (at least not any longer) I've had several instances of ruptures with water pouring in where my hull integrity was between 1 and 10, definitely positive.

  • Hull breaches with a positive hull integrity can occur from Tiger Plants shooting at you. ( I once had a set of planters with every kind of plant and wondered why my base kept getting leaks - I uprooted the Tiger and no more leaks) Jumping on the base with the Prawn or bad driving (crashing) with the Seamoth or Cyclops will also put holes in your base.

You seem to have the basics down, but be aware that the level of power delivered by a solar panel is dependent on light levels (night/day and ocean depth), and if your base is underpowered it will stop making oxygen/air. You might want to install a more reliable power source at your base.

Also, the distance (between power source and base) can cause problems, so best to avoid this problem by building your power source directly onto your base foundation.

    Yep. did all of that. It's definitely day time and the panel is on the base. Jun 30, 2016 at 11:29
