This is by far the best barge creation I've ever seen. It allows you to strike from anywhere on the ocean while letting you control the barge above the fumes. Credit for this creation goes to SteamG0D.
I've created a mothership, carrying 14 condensers, 2 tanks, an upgrade station, an artillery, an anchor (need it for the shield generator), a shield generator, an automechanic, a fabricator, a distributor, and an arsenal
Then i created another ship, with 8 tanks, and an ssim with tons of distributor caps (you get what i was trying to do)
i've created many versions of them, but they are usually the same, a huge platform, lots of condenser, tanks, and an artillery
