The news and information for marine surveyor, ship surveyors, cargo surveyors, marine cargo inspector, and the steps to conduct survey for draft survey, petroleum survey, bunker survey, includes marine survey software
A bunker quantity survey is taking measurements on board the delivery barge or at the shore tank and on the receiving vessel before and after transferring of oil takes place by involves an approved marine surveyors.
– Surveyor measurements the bunker tanks to determine the quantity of oil delivered.

What is VNET in Terms of Bunker Survey?
Remembered that unanswered question about Bunker Survey VNET by Surveyor on this site. We have collected two similar information to solve it.
QUESTION: Recently, many Chinese built vessels using the VNET calibration table for calculation of the bunker received on board and many a time, ended with dispute. What is VNET?
Even though the procedure has been tightened, we may see some bunker tanker are still trying to play their tricks, therefore it is very important for Chief Engineer, Vessel’s Crew and Surveyor to know well their tricks.
Below are the Tricks of Bunker Supply, trust that most of our Chief Engineers might known the trick very well, or even know more other tricks. Hopefully by knowing these tricks we can do some prevention, counteract or countermeasure to protect our interest:
1. Manipulating the sounding result
It is very easy for the bunker barge operator to manipulate the sounding result.
Counteract/Countermeasure: Chief Engineer or bunker surveyor appointed should sound the bunker barge tanks himself

I have added some software relate to oil calculation. The software are:
1. BunkerCal
A Bunker Tank Sounding calculation program. Bunker survey calculation for tank sounding report based on ASTM Table 54B .
Follow this link to know more http://www.sevensurveyor.com/software/surveysoft-marine-surveyor-software/
2. OilCal
A Petroleum calculation program. For shipboard survey with calculation and ullage report based on ASTM Table 6A, 6B, 54A and Table 54B.

Hope the software is useful. Please try it and drop your comment here.

The bunker calculation is simple and needs the following:
– Tank Sounding data and Tank Capacity Table. The Corrected Sounding means below is the sounding after correcting with vessel’s trim and list.
– Temperature of Oil on Tanks,
– Oil Density @15*C,
– Table ASTM 54B (VCF) and Table ASTM 56 (WCF).
Now we could go with sample of 1 tank to test the calculation.
What is Bunker Survey? The survey is carried out to measure and ascertain the quantity of Bunker on board at the specific time. This survey is produced the report that states the amount of bunker, usually Fuel Oil (FO) and Diesel Oil (DO), and sometimes Lubricating Oil (LO) is included.
