Welcome To Shore Tank, LACT meter Oil quantity and Alpha60 calculations
By GSS Ops Team
Oil Calc EU is a unique oil calculator with "three-in-one” capability for the calculation of
• Alpha60 factor used for the quantity calculation of special liquids by the Table 54C and the density conversion by the Table53C,
• Shore tank quantity calculation using Tables 54A, B, C, D and
• LACT meter quantity calculation using Tables 54A, B, C, D.
Shore Tank oil calculations
You can either manually fill in required input data for the calculation of the Shore tank quantity or you can download earlier saved Data
File in Excel format as shown on the below pictures:
The input data will be downloaded, and you only need to click “Calculate” button and, the program will calculate all volumes and tons:
You can select the standard of the calculation of CTL using option buttons:
either by the Table 54A (for Crude Oil or Gas Condensate), or by the Table 54B (for Refined Petroleum Products), or by the Table 54C
(for Special Liquids by means of the Thermal Expansion Factor alpha60 at 60°F per 1°C), or by the Table 54D (for Lube Oil):
The conversion of the test density at the test temperature of the shore tank sample into the density at 15°C will be carried out correspond-
ingly by means of either by the Table 54A (for Crude Oil or Gas Condensate), or by the Table 54B (for Refined Petroleum Products), or
by the Table 54C (for Special Liquids by means of the Thermal Expansion Factor alpha60 at 60°F per 1°C), or by the Table 54D (for Lube Oil).
You can also select several other options such as “Insulated or not” tank shell, calculation with or without a “Roof correction”, measure-
ments by the TankRadar or by the Tape measure, you can also select the material of the tank shell and the material of the tape measure to calculate properly shell correction.
The shell correction factor will be calculated differently for the upright cylindrical and for the horizontal cylindrical shore tanks. You just
need to select to tick or untick the option “Horizontal shore tank” as shown on the below pictures:
You can interpolate volumes of the product or the free water using a built-in interpolator:
You can save your input data and calculated results in the Data File in Excel format, you need to click on the submenu “Save Data File” of
the “File” menu as shown on the screenshot shown below::
Then your Data File will be saved in the Excel format as shown below:
You can jump to the Meter Report or to the Calculation of the Alpha 60 using the menu “Go To”:
LACT meter oil calculations
In the Meter Report calculations you can change the Table 54A, B, C, or D, the pressure units: bar, kg/cm2, kPa, or psi (pounds per square inch) and the source for the density used for the density calculation:
The above example of the calculation illustrates an option of calculations based on the test results of the in-line autosample (“the analysis of the in-line autosample”).
The second example of the calculation based on the observed average density measured by the in-line density meter (“the observed density by the in-line density meter”), the average observed temperature and the average observed pressure.
You can save your input data and calculated results in you Meter Data Report in Excel format and later you can download this data file to restore your calculations.
Calculations of alpha60 at 60°F per 1°F or per 1°C, the density at 15°C from test results
In your Alpha60 calculation report you need to fill in the all required input data obtained from the laboratory test results for up to 20 densities measured at different temperatures or to download such data from the Alpha60 Data File, then you just click on the “Calculate” button and, the program will calculate The Thermal Expansion Factor alpha60 at 60°F per 1°F or per 1°C, the density at 15°C, the density at 20°C, the density at 60°F using formulas from the API MPMS Chapter 11.1, the item 11.1.5.2 “Method to Calculate Thermal Expansion Factor from Density Measurements”:
You can use then calculated alpha60 at 60°F per 1°F or per 1°C and the density at 15°C for your shore tank or meter calculations. Of course, you can also save the input data and the results of your calculations in the Data file in the Excel format.
