Modding multiple shipyards per planet?

[ELN-Gustyboy]

Hi !
I am so sorry...
Thanks a lot for all this details....
But...i have a few more questions

The thing i don't understand is how the facility "gives" some resources to the SY without any ability...
is it the resources cost of the expansion facility which is gave to the SY during the construction of this expansion facility or something totally different(and in this case i think i am definitly lost...and i will have no choice...stop trying to understand...)

thanks a lot and sorry an other time...
Maybe someone who speak french and understand youre explaination will be able to translate all this to me...

bye !
