Damage can be manually repaired with the Repair Tool or automatically in the Seatruck Dock. Seatruck modules have individual health meters, though at present the game can only display the health of a maximum of five modules in the main cab display. The Seatruck Cabin can take damage from being below its crush depth, being attacked by hostile fauna, or by colliding with terrain or objects. The Seatruck Cabin has a health meter, and reaching zero will cause the cabin to explode, but leaves any connected modules unaffected.

The player can also manually detach the modules at any time by either going to the roof of a module and pulling it away, or pulling the lever on the left-hand side of the cab. When docking with a moonpool, all modules automatically detach to allow the cabin to enter the Moonpool. The Seatruck Cabin can be docked in either the Moonpool or the Seatruck Dock to recharge. The vehicle has its own Oxygen supply, and will replenish the player's oxygen unless the power has been depleted. It requires Energy to function, with sockets for two Power Cells on the top of the cab module. It is ideal for exploring the deeper biomes and for getting to places quickly and safely. With the ability to detach its front section, it allows the player to haul resources and equipment to an area of interest and then conduct exploration of even fairly narrow spaces without worrying about air supply. The Seatruck is an adaptable vehicle that can serve as anything from an agile mini-sub to a mobile seabase.
