Hull Integrity

Hull Integrity is a feature that currently affects Seabases. When the player is building their seabase they should pay attention to the hull strength, as it drops each time the player adds a module to their seabase. Once the seabase's hull strength, or Hull Integrity reaches 0 the seabase will flood with water, much in the same way as the Cyclops floods.

A seabase starts with a base integrity of 10, however, this does not include the additional +2.0 the foundation adds. The depth of your seabase influences how quickly Hull Integrity is reduced, and a seabase above water does not influence Hull Integrity. There is no Hull Integrity in Creative Mode.

Module Integrity Values

Each module in a seabase changes the value of the hull strength. Here is a list of current modules and their base changes (x1.0 depth multiplier) to seabase Hull Integrity:

Seabase element	Change to hull integrity	Notes
Foundation	+2.0
Corridor	-1.0
L-Corridor	-1.0
T-Corridor	-1.0
X-Corridor	-1.0
Hatch	-1.0
Bulkhead	+2.0
Ladder	N/A
Reinforcement	+7.0	+14.0 when built on the North, South, East, or West side of a room. This may be a glitch.
Window	-1.0
I-Corridor Glass	-2.0
L-Corridor Glass	-2.0
Room	-1.25	The game rounds the displayed number up to -1.3, but it is functionally -1.25
Observatory	-3.0
Moon Pool	-5.0
Water Filtration Machine	-2.0

Depth Multiplier

As you build deeper underwater, negative influences on Hull Integrity are multiplied.

• Negative changes are multiplied by the depth multiplier: a window that is built with a x1.5 depth multiplier will give -1.5 Hull Integrity (instead of -1.0).
• Positive changes to Hull Integrity do not vary by depth: a foundation will always give +2.0 Hull Integrity no matter how deep it is built.
• Anything above 100 meters does not affect the depth multiplier.

Formula for depth multiplier:

M = Depth Multiplier d = Depth

if d <= 0, M = 0 (There is no change to Hull Integrity above the water)

if 100 > d > 0, M = 1.0

if d >= 100, M = ((d - 100)/1000) + 1.0

What this actually means: Every meter after 100 will add .001 to the depth multiplier.

Depth Multiplier Chart:

Please note that the depth multiplier changes every meter, not just at the increments in the table. For example, a depth of 276m would have a depth multiplier of x1.176.

Depth	Depth Multiplier
<= 100m	x1.0
200m	x1.1
300m	x1.2
400m	x1.3
500m	x1.4
600m	x1.5
700m	x1.6
800m	x1.7
900m	x1.8
1000m	x1.9
1100m	x2.0
1600m	x2.5
2100m	x3.0
2600m	x3.5
3040m	x3.94 (Max Depth)
