Release the shipments

I'm a greedy eco player, but has to settle for a supremacy deck with a lot of unit shipments. This deck has a potential to send 36 shipments before age 5. My aim is to send as many as I can before the end of the game, and still gather most resources without long term eco cards. Looks like it can be done....what is the most number of shipments you sent in a sub 40 min supremacy game?
