Hello, It seems no terrestial pole can connect to the integrated pole that the Oil Platform has from Cargo Ships, meaning the pumps that fill up the ships done work. For now it can be avoided by going Oil pole -> Floating Pole - > Big - > Medium->Small, but maybe since the oil platforms use the medium pole sprite, make the same rules as the terrestial medium version?
After using this mod I have to say its brilliant, it makes the grid design and the small poles relevant again, when past early game you just plop the best you have and forget about it.
