Ok, now let us get back to basics of cargo calculations on tankers.
Pushkar Oct 30, Volumes are measured in cubic meters at some places and barrels like in the US in other Weight is measured in Metric tons at some places xstm in long tons at other places and barrels at 60 deg F at other places. There are different ASTM tables for crude oil and astmm product oils. Also, the volume is measured in Barrels and not in cubic meters. First, check what cargo surveyor has provided you.
So when in these ports, we need tble have the volumes in Barrels and temperature in Deg F. Thank you sir, for explaining complicated topics in such a lucid manner, its an art The density at 15 Deg C is always the density in Vacuum. Boris Sep 26, This is true especially for vegetable oils Correct me if I am wrong.
And as you might have guessed correctly, these ports also do not measure the temperature in Deg C but in Deg F. But for petroleum products and crude oils, ASTM tables are used for calculating cargo weights.
Basics about Volume and weight Before we proceed to the complex things, it is better to start with the basics. And even for the main ASTM tables, the information about which table taable to be used for cargo calculation is provided by cargo surveyor.
This podcast on the maritime matters will provide value to the listeners. tablw
And to do that we need to apply the volume correction factor. Short, crisp and full of value. Sometimes it is difficult to understand which one to use and why. Thank you very much for your kind effort for explaining cargo calculation in a very simple language.
And when we multiply the volume at observed temperature with VCF, we get the standard volume, this time the volume at 53 Deg F.
Remember volume changes with temperature. Here is all you need to know. Amit Yadav Sep 26, So, in this case, we just apply these densities to get the weight of cargo in each tank and thus the total weight of the cargo.
We make sure that there are least constants on the ship, the aastm is pumped out to the last drop and many other things like these. Ivan Sep 23, But here is the thing.
ASTM Table 53 / 54
Here is how the ullage report will look like. As the volume changes with the temperature, this cannot be the measure of how much cargo we have loaded or discharged. Jorge Belalcazar Cardona Sep 29, Knowledge dies if it remains in our head. Krishna kumar Nov 10, So in our case, the Sstm would be: Rajeev Jassal Oct 7, This is even easier than the previous section that we discussed.
ASTM Table 53 / 54
Stay tuned for this section. These detailed and well researched articles provides value reading for all ranks. When we apply this WCF to the standard volume, we get the weight of cargo in Air. The cargo surveyor may provide a table of densities at different temperatures. But we need to understand that at the very basic level, we calculate the volume from ullage tables and we need to be provided with density at the same temperature as the cargo.
We multiply both and we get the weight of the cargo. ast
This is the reason “Albert Einstein Quotes. And it is not that complicated. Glad you found it helful Jorge. In this case, we need to get the volume correction factor VCF to convert the volume at the observed temperature to the standard volume which is volume at 15 Deg C or Volume at 60 F respectively.
Well, the weight is Vacuum is always more than the weight in Air. Ok, so now here is the first thing that we can learn.
