PlanetsCentral

Using the colonize mission, ships can land on planets, be unloaded and disassembled, to start a new colony. You use that only if you want to get rid of a ship, normally, it suffices to unload colonists to start a colony.

Colonist_clans_on_planet =
   Colonist_clans_on_ship + Trunc(Ship_crew / 100) + 1

Neutronium_added_to_planet =
   Neutronium_on_ship

Money_added_to_planet =
   Money_on_ship

Tritanium_added_to_planet =
   Tritanium_on_ship + Trunc(RecycleRate * Tritanium_built_into_ship / 100)
   ...with
      Tritanium_built_into_ship =
         Hull_tritanium_cost
         + Engine_tritanium_cost * Num_engines
         + Beam_tritanium_cost * Num_beams
         + Torp_launcher_tritanium_cost * Num_torp_launchers

Duranium and Molybdenum are recycled according to the same formula as Tritanium.

Note that ammunition on the ship is not recycled, and does not yield minerals for the colony.
