And even for the main ASTM tables, the information about which table need to be used for cargo calculation is provided by cargo surveyor. Converting weight in Vacuum to Weight in Air and vice-versa Ok, so now here is the first thing that we can learn.

This is true especially for vegetable oils Correct asym if I am wrong. There are so many tables to use and so many terms that float.

If we multiply these two, we 533a the weight by a simple formula. MySeaTime Podcast This podcast on the maritime matters will provide value to the listeners.

ASTM Table 53 / 54

Remember volume changes with temperature. Anthony George Johnny Sep 25, We make sure that there are least constants on the ship, the ballast is pumped out to the last drop and many other things like these.

Always waiting for more articles. Thank you sir, for explaining complicated topics in such a lucid manner, its an art While the ASTM tables that we discussed in previous sections are the one that is used mostly, there are other ASTM tables that supplement these main tables. The cargo surveyor may provide a table of densities at different temperatures.


But here is the thing. Stay tuned for this section. We need to apply Weight correction factor WCF to the standard volume to get the weight of the cargo.

ASTM Table Series for Oil Survey

So when in these ports, we need to have the volumes in Barrels and temperature in Deg F. Will try to write on similar topic for LPG. And we call this as weight correction factor WCF.

And it is not that complicated. Rajeev Jassal Oct 14, Not because these are difficult but because there are so many variations to it. Rest of the calculations is the same as what we discussed in the previous section. Sstm you verymuch sir. Tun Oct 18, Really helpful sir, I am preparing for Ch Mates phase I exams ans as I am from a dry cargo background, this artice really helped me out.

Coming back to the topic, can you guess for the same amount of cargo which weight would be more? Weight in air or weight in Vacuum? In above ullage report, I have applied the WCF to the Gross standard volume but we can easily make one additional column and apply the WCF to the standard volume of each tank to get ttable weight in the air for each tank. If you can’t explain it simply, you don’t understand it well enough”. There are no standard tables for chemicals.


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. Adtm for these ports here is what the volumes and temperatures in ullage report would look tablf.

The density table could look zstm like this. We do so many things to make sure that ship owners get the maximum out of their investments on buying and running a ship. Conclusion Cargo calculations are sometimes tricky. Knowledge dies if it remains in our head. The cargo calculations, in this case, are also easy. This means that Density at 31 Deg C would be: And as the density also changes with the temperature, we would need the density of the cargo at the cargo temperature to convert the observed volume to weight.
