This article is about Bulkhead in Subnautica. For the related article on the Below Zero Wiki, see Bulkhead.

The Bulkhead is a Seabase module. It is constructed with the Habitat Builder and can be placed inside seabases at the ends of Basic Compartments.

The Bulkhead increases the Seabase's hull integrity level by 3. The Bulkhead can be opened and closed to stop flooding from going into another section of a base. Note that this is only a temporary solution if the Seabase's hull integrity is too low, because breaches can just as likely appear on the other side of the sealed-off passageway. However, they are completely effective at preventing flooding caused by damage to a single room (for example, from a Cyclops collision).

How to use

  • Open Builder menu (RMB) and select Bulkhead.
  • Place it (Green ghost model will confirm placement).
  • Click on the door to open and close.

Bulkheads can only be built in "compartment" sections: they cannot be placed in the automatically generated corridor sections some room types create when placed in proximity to each other.

Data Bank Entry

The bulkhead door is designed to separate compartments while reinforcing structural integrity with its solid titanium frame. The door can be opened and closed to seal off compartments in the event of fire or flooding, or simply for privacy.
