Crushed stone ring foundation
(OP)
I am involved in the design of a oil farm tanks. this IS my first involvement in such project. Does anyone guide me with the design of the ring crushed stone below the tank shell? The inside of the ring is filled with compacted sand.

For my one petro tank project years ago, the geotech report (provided by the client) even included a recommended gravel foundation design. If you commission a geotech report, ask the geotech engineer to do the same.
Most of my tanks have been for potable water and used concrete ringwall foundations. The gravel foundation was a new one for me. IIRC, we had two 60,000 bbl and two 80,000 bbl tanks, 40 feet tall, and the gravel foundations in decent soil were something like 3 feet deep over the entire footprint of each tank and extending 5 feet outside the shell....something like that.

Years ago, before "oil" became a frightening word to environmental engineers, we used to thoroughly mix sand with oil to make the base pad for the tank bottom. That probably saved the lives of a lot of tanks from an early corrosion death!
