Landfill - A must have. The new mods section made the download near impossible to find. Here it is to spare you time: https://forums.factorio.com/forum/vie ... 91&t=4973&
Ore Processing

A fairly standard setup for ore processing. You can also see my steel production on the left. It feeds into my piercing ammo and engine production. On the right is a stone deposit. I'm making landfills and stone bricks.

Red and Green Science

I thought staggering the red science was cool. I also put some chests so I could get circuits, transport belts, and inserters easier. I also snuck in some ammo and engine crafting.
After I made the image I added some more science labs, and it could probably handle more.

Power and Defense

The turrets are loaded with piercing ammo. I probably have way to many burners. I haven't researched gates yet, but it will go between the left turrets. Off to the right is a big oil area that I'm going to start drilling.

Map

Overall the base is easily defend-able and the pollution will go over the ocean so its not a problem. The is lots of oil and ores close to the start area which is good.
The download is all yours

NOTE: The download is a little ahead of the pictures. I just added some oil stuff and defeated that south base.
