Hull Integrity

Hull Integrity is a feature inherent to a Seabase.

An arbitrary number of habitable modules directly connected to each other constitute one Seabase.

A Seabase always has a base integrity of 10. Each module that is part of the seabase adds or subtracts to this base value. Additionally, there is a Depth Multiplier. Modules located above sea level are exempt from the hull integrity system: modules will not subtract from integrity, and reinforcements will not add to it.

The hull integrity is only displayed when adding a module to, or removing a module from the seabase.

Example: a seabase at a depth between 0 and 100m, constituted out of one I Compartment and one hatch has a hull integrity of 8 (10 - 1 - 1). If the player builds another I Compartment in parallel to the first one (near enough to it), it will be part of the same seabase and further reduce its hull integrity by -1 to a total of 7.

Once the seabase's hull integrity reaches zero, hull breaches will appear randomly, and the modules will start to flood. A closed bulkhead between modules will keep the flooded area sealed off, but as more breaches will appear randomly over the entire seabase, the only mitigation is to raise the hull integrity above zero. Breaches must be repaired with the Repair Tool.

Hull Integrity is disabled in Creative Mode.

Module Integrity Values
Each module of a seabase affects its hull integrity. Here is a list of current modules and their base changes (x1.0 depth multiplier):

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 between 0 and 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 0 < d < 100, M = 1.0

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

What this actually means: Every meter after 100 will add 0.001 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.
