Seabases

Seabases are installations created by the player through the use of the Habitat Builder tool.

Many different modules are available to allow the creation of unique Seabases. One of their primary applications is to provide an area where the player can return for Oxygen and serve as an alternative to the Escape Pod as a base of operations.

Seabases can be customized in the same way as the Cyclops through the installation of Lockers, Wall Lockers, Fabricators, Specimen Analyzers, Benches, Signs, and Aquariums.

Abandoned Seabases can be found at the center and on the tops of the mountains of the Floater Island. Another is located in the Jelly Shroom Caves. All of them have fallen into disarray and cannot be interacted with.

Hull Integrity


Hull Integrity refers the ability of your Seabase to withstand the pressure of the surrounding water. The majority of the Seabase modules will lower the integrity once added but the amount will vary by module. As Seabases are built at a greater depth the integrity reduction caused by each module will increase. Hull integrity can be increased by constructing Reinforcement panels, placing your Seabase on a Foundation, or installing Bulkheads.

When the hull integrity of a Seabase reaches zero, it will begin to form hull breaches. Any corridor or room that is connected to the breach will fill but Bulkheads allow the player to compartmentalize the base and prevent floodwaters from moving between compartments. However, if the integrity remains below zero then eventually every compartment will develop a leak and the base will fill completely with water. To avoid this, quickly increase the integrity and fix all hull breaches in the base using a Welder.

Energy Usage
Energy can be provided to a Seabase by building various types of generators near the Seabase. Placeable Items such as the Fabricator will drain energy from the Seabase.

Seabases do not require energy to operate devices in Freedom Mode. A notable exception to this is the ability to dock a Seamoth in a Moon Pool, which does require power.

Oxygen
Seabases produce Oxygen naturally, but requires power to do so. If the power is depleted, the Seabase will slowly lose oxygen, until it is completely gone.

How to Build a Seabase

 * 1) Find a suitable flat piece of land, or terraform the environment with the Terraformer. Placing a Foundation also flattens the terrain.
 * 2) Equip the Habitat Builder, click the RMB to bring up a crafting menu.
 * 3) Select the desired module.
 * 4) Look at the desired building place (the outline of the module will become green if the location is valid).
 * 5) Adjust the rotation by pressing Q or E or by scrolling the mouse wheel.
 * 6) Place the module by clicking the LMB.
 * 7) Once placed, hold the LMB to finish the building process.
 * 8) Go to Step 2 and repeat.

If you want to deconstruct a Seabase module, equip the Habitat Builder and hold "E" while facing the module. The materials used to create the module will be returned to your Inventory.

Sounds
The Seabase's AI makes two different sounds. Those are:

Welcome message
This message will play upon entering your seabase or seamoth.

Power restoration
When the power to the Seabase is restored, the AI informs you about it.

Available Modules

 * Please note that negative changes to Hull Integrity do increase with depth. For more information see Hull Integrity.
