In my last post How To Conduct Bunker Survey, I have explained the general step for Bunker Survey conducts. Now, the topic is about the way to calculate ship bunker that we have found on the ship tanks. It is suggested to read the last post to become familiar with calculation.
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.
