From: The Big Nowhere
Easier to set up a bunch of convoys to do the 'milk runs'.
Send a major task force from your home port loaded with fuel, set it to computer CS and let it repeat the trip over and over to a forward supply dump. Then from that forward dump make a bunch of small task forces the same way, hauling the fuel from the forward supply dump to places you need it again on repeating CS convoys.
As the IJN, I run a big tanker (or AK loaded with fuel) convoy out of Tokyo using my 10k plus tankers and/or large AKs. I send this one to either Saipan or Truk, and from their I use smaller AKs or singles of those 1200 load tankers to take the fuel to places like Palau, Kavieng, Rabaul, etc.
In other words, you make a convoy supply chain, instead of depending on one ship to do all the work, you use several ships to handle the job (its also not as devastating to the supply situation when you lose a single ship to subs). Another advantage of this is you do not have to babysit it like you would using the single ship method of go here, unload one turn, send it to the next stop, etc.
