Bulkhead (Subnautica)
Overview
The Bulkhead is a Seabase module constructed with the Habitat Builder. It is placed at the ends of I Compartments to provide structural support and prevent flooding. When closed, it seals off sections of the base.
Key Statistics
- Category: Seabase Module / Interior Piece
- Hull Integrity: +3 Units
- Acquisition: Fragments (Found in [Degasi Seabases](/wiki/degasi-seabases) and on the Floating Island)
- Construction: Requires Blueprint and Habitat Builder
Description
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.
Using a Bulkhead is a temporary solution if the Seabase's hull integrity is too low, because breaches can 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 the Builder menu (RMB) and select the Bulkhead.
- Place it where a green ghost model confirms valid placement.
- Click on the door to open and close it.
Note: Bulkheads can only be built in "compartment" sections. They cannot be placed in automatically generated corridor sections created when certain room types are placed in proximity to each other.
