Rajeev Jassal Oct 7, 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.

Always waiting for more articles. The previous two methods are useful and applicable for cargoes the density for which changes proportionally with temperature. If you can’t explain it simply, you don’t understand it well enough”. So how these calculations are performed on chemical tankers??? But what if we are provided with API gravity at some other temperature, say at 80 deg F? Tablle George Johnny Sep 25, Well, the weight is Vacuum is always more than the weight in Air.

Density at a particular temperature and correction factor So let us say that cargo surveyor has provided us with the density at a particular temperature and correction factor.

There are no standard tables for chemicals.

Density at 15 Deg C and ASTM table to use The previous two methods are useful and applicable for cargoes the density for which changes proportionally with temperature. He has done extensive research on quantitatively measuring Safety culture onboard and safety climate ashore which he believes is the most important element for safer shipping. And we call this as weight correction factor WCF. Thank you sir, for explaining complicated topics in such a lucid manner, its an art So for these ports here is what the volumes and temperatures in ullage report would look like.

Rest of the calculations qstm the same as what we discussed in the previous section. Sometimes it is difficult to understand which one to use and why.

awtm 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. Thanks for sharing ur knowledge. Written by Capt Rajeev Jassal on September 23, How to convert weight in Vacuum to weight in Air? Get your hands on ASTM tables and you will find that cargo calculations are not as difficult as it seems.

Remember, for stability and draft calculation we still would need to use the weight in air. We need to follow the information provided by the cargo surveyor because that would be the table that is used for shore calculations and we need to use the same to avoid ship shore quantity difference. Let us say we are interested in calculating the weight in Metric Tons in the air. Let us say the cargo surveyor has provided the API gravity at 60 F to be The first page of the ASTM table 56 provides tabe factor for converting weight in vacuum to weight in air and vice versa.

Ok, now let us get back to basics of cargo calculations on tankers.

The density at 15 Deg C is always the density in Vacuum. Ask or answer a question on this forum. Not because these are difficult but because there are so many variations to it.

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 5a the standard volume of each tank to get the weight in the air for each tank. There are so many tables to use and so many terms that float.

All this to make sure that we have the capacity to load maximum cargo and ship owner has a chance to earn maximum from it. Suvasmit Chatterjee Nov 9,
