Unit Module (S)

T1

Cargo Depot module for transferring unit materials (such as Wood). It can be built in any empty slot of a Cargo Depot.

The Unit Module (S) is a small-capacity storage for unit products which automatically unloads Cargo Ships. It features storage for 180 units and two output connections for Flat Conveyors (or their variants).

Unloading the compartment of a Cargo Ship with this module takes 40 days which equates to 135 units /60s. This rate is almost an exact match to the throughput of the Flat Conveyor II. It should be noted that the round trip ship transit time (from one docking to the next) is exactly 3 months. At 130 days per cycle, this equates to an average throughput of 62 units /60s or almost exactly the throughput of one first-tier Flat Conveyor.

Resource selection

After construction, Cargo Dock modules require the desired cargo to be set in the module's UI window. However, as of Beta 0.3.10 (2022-01-15) there is only one unit product cargo available, Wood, so it is automatically selected for the player once the Sawmill has been discovered, repaired, and staffed with Workers.

The cargo selection of adjacent modules, and even the types of modules themselves, can be mixed-and-matched as desired. It should be noted that modules which share a Cargo Dock are frequently built in identical pairs for ease of Cargo Ship management. As a Cargo Ship will wait idle for several months before venturing back out if not fully unloaded, mixing of module types can result in a situation where the ship waits for extended periods for the less-utilized cargo type to be empty before departing, causing reduced throughput or shortages of the more-utilized cargo type.

Module throughput vs resource extraction

Given the average throughput with the Cargo Ship round trip time factored in is 62 units /60s, the following comparisons can be made:

• One small Cargo Dock module can continuously outpace production from a 1-shift outpost (at 43.5% duty cycle)
• One small Cargo Dock module can continuously outpace production from a 2-shift outpost (at 87.1% duty cycle)
• Two small Cargo Dock modules can continuously outpace production from a 3-shift outpost (at 65.3% duty cycle)
