Please remember that normally the density or API is provided by the terminal or surveyor in the load ports and what is used will be dependent on the region/port of loading. WebThe renal volumes were calculated using the slice summation method, the ellipsoid formula with /6 as correction factors as well multiple other correction factors for statistical Volume correction factors to The Final UUC Reading will become now your final value to be applied during your measurement process. This volume is usually referred to as displaced volume or actual volume (V A). Water layer existing as a separate phase in the tanks, normally detected by water-paste or interface detector and usually settled at the bottom of the cargo tankdepending on relative density of the cargo. 2015 May;47(5):851-9. doi: 10.1007/s11255-015-0959-3. 0000001696 00000 n Your email address will not be published.

Distance over the ground (GPS distance) cannot be used if the slip calculation is required to provide a meaningful figure, using the log distance (the distance the propellor actually moves the vessel through the water) provides an almost true indication of the work actually done by the propellor, with wind and sea state being remaining sources of error. You can apply this technique if a small difference does not have a significant impact on the results, or it is negligible because of a wide tolerance limit or the effect of resolution (low resolution instrument), then this is a quick way to determine and estimate the correction factor. You are interpreting a calibration certificate but you noticed that the correction factor you need is not exactly displayed or provided in the report, what can you do? The corresponding values of each tank are tabulated for easy reading and the total weight of bunker quantity is calculated.
