What are the relevant book standards that can be referred to for the design of the zero-level tank used when unloading heavy oil by train?

Dear sea friends, when unloading heavy oil trains, how are the zero-level tanks designed? Do they all need to be buried underground? If it is buried, will the oil transfer pump be underwater or above ground? If it’s on the ground, the tank cannot be buried too deep, otherwise cavitation will occur. With a capacity of 800 cubic meters, is it reasonable to design a tank with a diameter of 19 meters and a height of 3.5 meters? Additionally, what are the reference book standards? Seeking advice.
Typically, the oil transfer pump is located below the floor level.
The elevation of the pump room is the same as that of the oil tank; when a zero-level tank is built, a zero-level pump room is also constructed at the same time. Furthermore, if the required effective volume is 800 cubic units, then the designed volume will be much larger than 800 cubic units. The liquid guide pipe for unloading must be below the floor level. If you set the height at 3.5 meters, the entrance of the liquid guide pipe into the tank will be much lower than 3.5 meters, which means the effective volume available will not be sufficient
Why is the inlet for the liquid guide pipe much lower than 3.5 meters?
