Centralized Shipyards Stellaris

Centralized Shipyards Stellaris

Simple:
Activate “Central Shipyard” edict on your shipbuilding planet.
Activate “Supporting Shipyard” edict on other planets with spaceports.
Profit!

Detailed:
You can set every planet a “Supporting Shipyard” which reduces their shipbuilding speed by 50% and creates a “One Supporting Shipyard” modifier which increases shipbuilding speed by 33% provided it has a Spaceport. So even without a “Central Shipyard” it decreasses its shipbuilding speed by 17%.

You can set one planet as “Central Shipyard”, if you enable the edict on another planet the old one becomes a “Supporting Shipyard”. If you have a “Central Shipyard” it will get all “One Supporting Shipyard” modifiers provided it has a Spaceport.

You can automate the Centralization of Shipyards with a policy which will make all planets “Supporting Shipyard”, you will still be able to change which planet is the “Central Shipyard”. Be aware that you have to wait 10 years before you can change the policiy again!
