Even though on ships it is more common to measure the cargo weights in the air, sometimes you may find that the charterers would give the requirements for measuring weight in Vacuum.
Pls next how to calculate: So in our case, the WCF would be: About Capt Rajeev Jassal Capt. He has done extensive research on quantitatively measuring Safety culture onboard and safety climate ashore which he believes is the 53w important element for safer shipping.
ASTM Table Series for Oil Survey
So for these ports here is what the volumes and temperatures in ullage report would look like. Different manufacturer may have different densities for same chemical. Here is how the ullage report will look like.
We multiply both and we get the weight of the cargo.
Even when we hear some weight of cargo, let us say Tons of cargo, there are two things that we need to be aware of. Seafarers Question Answers Ask or answer a question ast, this forum.
Ivan Sep 23, So as we can see for temperature 34 Deg C, the volume correction factor is 0. In air or in Vacuum Apart from the units, weight is measured in air or in Vacuum. Let us say we got the volumes from the ullage tables atm the volumes for each tank are as per below.
Knowledge dies if it remains in our head. Your work is greatly appreciated, Sir! Rajeev, Above well explained.
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. Thank you sir, for explaining complicated topics in such a lucid manner, its an art Really helpful sir, I am preparing for Ch Mates phase I exams ans as I 35a 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? So here is what we have.
ASTM D – ROFA Products
Here is all you need to tablf. When we apply this WCF to the standard volume, we get the weight of cargo in Air. We need the density of the cargo to convert the volume of cargo to the weight. Short, crisp and full of value. There is a simple formula to convert these.

Anthony George Johnny Sep 25, And as you might have guessed correctly, these ports also do not measure the adtm in Deg C but in Deg F. Ok, now let us get back to basics of cargo calculations on tankers. Thankyou sirvery well explained in simple words with deep explanation. Here is how the ullage report would look like so far.
ASTM Table 53 / 54
Vapour weight in LPG But there are other ASTM tables that supplement these tables that we discussed so far. The first page of the ASTM table 56 provides the factor for converting weight in vacuum to weight in air and vice versa.
Thank you so much for sharing your knowledge in such a simple manner.
