Thanks for sharing this topic. I've been slurping information off this forum for over three years and I continue to learn new things all the time. I play Allies against the Japanese AI (I'm just not a good PBEM candidate). Santa brought me a new tablet & mobile hotspot for the holidays and I've resolved to begin participating in these topics).
Somehow I've managed to overlook the refineries in Australia. My current game is dated Oct 15th, 1942 and I now need to shift some tankers to hauling oil from LA to Sydney. I'm thinking I'll split one tanker from the TF at LA upon arrival, load it with Oil, then transfer it back into the convoy upon departure for Sydney.
With all the tanker capacity the Allies have, it's usually not a problem to keep the fuel flowing to Australia. My set up is very similar to wdolson's comments, I also run some 12000 endurance tankers from Abadan to Perth (using waypoints that hug the eastern map edge, and refueling at Perth for the return trip).
One lesson learned, after a large amphibious landing at Milne Bay, upon returning to Townsville the transports and AK's sucked up all available fuel. Going forward I need to remember to include some loaded AO's in the staging area.... all the little things about this game keeps me addicted.
Loading oil at LA will take forever. There just isn't the quantity in excess of local refinery demand. It will do it after a time, but it's a misuse of a good TK IMO. The amount of supply generated by the Oz refineries is tiny and not worth hauling oil. It just isn't. Give Sydney the same fuel--right now--and the HI machine will crank out supply in six-figures.
There's another Perth/fuel option I don't think I've ever seen in the forums. Works well from mid-42 until it doesn't matter anymore. As I've long advocated, move huge numbers of refugee xAKs off-map to CT as soon as possible at war's start. Run a couple of EC-to-CT cycles with them on fuel to get over the initial CT hump. At the same time run TKs from Abadan to Karachi. This will flow mostly to Bombay. Don't know why, but it does. By the summer Bombay often has 800,000 or more fuel to run its HI. Far in excess of reqs. At the same time CT has gotten many free convoys in full of mostly supply, and you need supply in Burma. If you set the spinners right supply will easily flow to Calcutta and be available for distribution into Burma during the monsoon. You can pull Bombay dry of supplies easily while it sits on close to a million fuel.
So. By mid-1942 shift off-cycle xAKs from the EC run, and load them with supply at CT. Run them to Bombay to fill that pipe for Burma. And backload them with FUEL (Abadan fuel originally) to haul BACK to CT. At CT re-load this fuel for Perth with dedicated CT-to-Perth xAKs. Big and fast ones.
What's the advantage? Running map edge to Bombay is a low submarine enviro. Running Abadan to Karachi is the same. Running CT to Perth is much safer than running Abadan to Perth and back. In general there is an IO Rule: go E-W as much as possible. Avoid N-S. This scheme minimizes exposure time to subs, and gets work out of the Bombay-to-CT backhaul route.
