Typical Deisel Generator Oil Storage Systems
(OP)
I am having a tough time rounding up info. on how to best approach designing a Deisel Oil Generator Storage system. I have 2 larg storage tanks needed for a 3 day supply that will feed 5 day tanks each feeding a gen-set. The gen-set needs 500 l/hr. I have selected the tanks and generator but have not determined the pipe size or the pump size yet. I think the day tanks will be batch filled, but I haven't decided on a rate of filling. I concerned with the system going from the storage tanks to the day tanks. Does anyone have any suggestions as to some of the particulars that I will need to concider for this system?

They are also often set up so they can be run continuously to 'polish' the fuel in any tank, running it through a water separator and filter and back to the tank, to remove the junk from a bad batch of fuel.
Beyond that, I know nothing.

RE: Typical Deisel Generator Oil Storage Systems
Look at how many hours you want to spend filling up all the day tanks (from zero), while all gen sets are running. That will give you the minimum pump rate.
So, (pump_rate - 500 l/hr)* pump_hrs = 40000
4000/pump_hrs = pump_rate - 500 l/hr
pump_rate = 4000/pump_hrs + 500
Say 1/2 a shift = 4 hours,
pump_rate = 4000L/4hrs + 500L/h = 1500L/hr
Note, as you increase the hours needed to fill, the flowrate drops by a power function approximating
(4000+500)^(4000-500)/(4000+500)
If you plot that and draw the tangets, you get a rough intersection at 2000 L/h, which I always thought was a reasonable (optimum?) max. So somewhere between 1500 and 2000.
Size the line for 2 m/s velocity.

Anyway, I assume you get the idea. Base it on a reasonable refill time with all tanks hitting empty at the same time. It will happen.

RE: Typical Deisel Generator Oil Storage Systems
We design our main pumps to empty the tanker in maximum 1 hour and thus it is 12cu.mtr/hr. If you go with that capacity and start pumping into day tanks when the level is 1000 liters then you require about one and half hour.
It doesn't matter much, with respect to total power consumption, whether you take a small pump and run for many hours or take a big pump and run for lesser hours.

The head engineers here are insisting that I use double walled piping. They are super concerned with spilage. Do you have any extra comments regarding this. I'm not sure that I mentioned that this system is for a Mine. I don't know if that makes much difference but I just thought I would mention it.
RE: Typical Deisel Generator Oil Storage Systems
I would be much more concerned about spillages in the storage tank area. Otherwise its just a matter of keeping excavation or other machinery away from the line in some effective manner.
