Hello, How are you?

In the vacuum, there is no buoyancy and hence the weight is more than the same weight when measured 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 the provided values are Density at 25 Deg C: Things as simple as cargo calculations. Written by Capt Rajeev Jassal on September 23, Just wanted to know one thing how calculations are performed on chemical tankers.

These methods are mostly used for calculation of chemical cargoes. Volumes are measured in cubic meters at some places and barrels like in the US in other Weight is asstm in Metric tons at some places and in long tons at other places and barrels at 60 deg F at other places. We wstm the volume at 15 Deg C and we have the density at 15 Deg C. There is a simple formula asrm convert these. If that was not enough, humans on this planet earth have managed to confuse it further.

We just take the density of the cargo to the corresponding cargo temperature that we measured. Basics of cargo calculations Ok, now let us get back to basics of cargo calculations on tankers. 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. We multiply both and we get the weight of the cargo.

Let us say we are interested in calculating the weight in Metric Tons in the air. In this case, we need to get the tabel 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.

Different manufacturer may have different densities for same chemical. Getting the weight from standard volume is simple. This is even easier than the previous section that we discussed. Thank you sir, for asfm complicated topics in such a lucid manner, its taable art Krishna kumar Nov 10, 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.

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. Conclusion Cargo calculations are sometimes tricky. So here is what we have.

Short, crisp and full of value. Follow us Today on our social network. Suvasmit Chatterjee Nov rable, And when we multiply the volume at observed temperature with VCF, we get the standard volume, this time the volume at 60 Deg F.

But in any case, we still need the weight asm the cargo as the stability calculations need the weight of the cargo in each tank and not the standard volume. If you can’t explain it simply, you don’t understand it well enough”.

ASTM Table 53 / 54

We need to convert the volumes to the weight of gable cargo in each tank. Unit of weight What is the unit of this weight? Very nicely explained sir.

First, check what cargo surveyor has provided you. A Table of densities at different temperatures The cargo surveyor may provide a table of densities at different temperatures. Tablf, the weight is Vacuum is always more than the weight in Air. Ask or answer a question on this forum.

Pushkar Oct 30, Your work is greatly appreciated, Sir! Go to myseatime blogs.

Boris Sep 26, Basics about Volume and weight Before we proceed to the complex things, it is better to start with the basics. It is sometimes difficult to get a hang of these calculations.

ASTM tables tzble any letter are common for both crude oils and product oils. Now the final ullage report will look like this. Ok, now let us get back to basics of cargo calculations on tankers.
