Cargo Depot (4)
The Cargo Depot (4) is a large auxiliary dock which allows for a Cargo Ship to dock at the island once one has been discovered and repaired. It features a flat dock space with connection slots for the addition of four (4) Cargo Depot modules, a 120 unit Diesel tank for refueling Cargo Ships, and an accompanying Pipe connection to replenish itself.
In order for the Cargo Ship to arrive and be able to unload cargo, the player must attach and build at least one Unit Module (M), Unit Module (M), or Fluid Module (M). While there are also lower-capacity (S) variants of each of these modules, the larger side modules are unlocked by the same Cargo Depot II research which unlock the Cargo Depot (4) itself. As a result, pairing of the (4)-size dock with the (S)-size modules is uncommon.

Cargo Depot spacing and placement
Placement of Cargo Docks on uneven shorelines is often tricky. The player can ease placement through strategic dumping of excess materials, such as Slag or Rock to create a straighter and more level shoreline.
To prevent blockage (assuming they are placed along a parallel shoreline) a minimum of 50 tiles of space is required between the structural part of the depots.
