I am a non-seafarer; but fortunate to be trained under Master Mariners/ Chief Engineer/Naval Architect and shaped up as a Marine Surveyor. I passed Associate Exam of Federation of Insurance Institutes , .Mumbai ( presently called as Indian Institute of In
ASTM Table 54 stands for evaluating VCF (Volume Correction Factor). On vertical side Tank Temperatures are given and horiontally Density @ 15 Deg C are given. Corresponding value for Tank Temperature and Density @ 15 Deg C is VCF.
Now it comes to one mind, as to how to calculate Density @ 15 Deg C. You have to draw a composite sample of crude or product and measure the sample for Temperature and Density and use ASTM Table 53, to evaluate Density @ 15 Deg C. In Table 53, Vertical side you have Sample Temperature and horiontally Sample Density and the corresponding value is Density @ 15 Deg C. Having calculated Density @15 Deg C and VCF, calculation of quantity is as under-
Gross Volume (A) -Unit in KL
Less : Water Volume (B) Unit in KL
Nett Volume @ NT (A-B) - C Unit in KL
Tank Temp Unit in Centigrade
Density @ 15 Deg -- D - Unit in Kg/L
VCF (using Table 54) E - Factor
Volume at 15 Deg C - C * E - F Unit in KL
WRF ( Density @ 15 Deg C- 0.0011 ) - G - Factor
Quantity in Air F * G Unit in Metric Tonnes
Quantity in Vac F* D Unit in Metric Tonnes
N.B : When softwares available to calculate VCF and calculations, I am afraid if anyone resort to basics.
