loss of oil during transportation

loss of oil during transportation

(OP)
Can anyone help me to give information regarding the acceptable level of oil loss during transportation (by sea tanker)? Currently we use "magic number" of 0.5 % but I dont know where the number comes from. Is there any international standard or any reference on that matter?

Thanks

RE: loss of oil during transportation

The 0.5% has nothing to do with acceptable loss. Imagine from a 500.000 barrels tanker, you cannot throw 250 barrels in the sea or in a US port.

It has to do with differences in inventory transfer. If you were transferring discrete units (coconuts, tractors) the "acceptable loss" would be 0. Bulk tranfers (barrels, kg, tonne, liters) have a lot of inherent factors that reduce exact measurement.

RE: loss of oil during transportation

Oil volume depends on temperature.
If temperature increased you could get a + change. The volume received would be more than the volume shiped.
For transformer oil, the expansion is

Thermal Expansion, 68-158degF ml/ml/degF  0.0004

For 20degF change in temperature, I calculate a 0.8% change in volume.
