Pre 1980
If a volume correction method with the 1980 designation is selected. The following
formula is used to calculate Gross Volume:
Where:
Japanese correction methods
If a volume correction method with the 'Japan' designation is selected. The
following additional options are available:
Where:
VCF = Volume Correction Factor
NSV = [(GOV - FW) x (1.0-%BS&W/100.0)) x VCF]
NSV = Net Standard Volume
FW = Free water + Tank Bottom Solids (if any)
FRA = Floating Roof Adjustment
%BSW = Percentage of bottoms, sediment and water impurities
VCF = Volume Correction Factor
NSV = [(GOV - FW) x (1.0-%BS&W/100.0)) x VCF]
NSV = Net Standard Volume
GOV = Gross Observed Volume
FW = Free water + Tank Bottom Solids (if any)
%BSW = Percentage of bottoms, sediment and water impurities
VCF = Volume Correction Factor
Water not subtracted
The value of FW in the net volume calculation is
always zero
Water Subtracted from
Net Volume
The FW value is subtracted from the TOV as
defined above
Water Subtracted from
Gross Volume
The FW is zero in the net volume calculation, it
is subtracted from the Gross Volume (see
above)
VSW not subtracted
The value of %BSW in the net volume
calculation is always zero
NSV = Net Standard Volume
