Bunker Survey Calculation

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.

Bunker Survey

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 @15C,

– Table ASTM 54B (VCF) and Table ASTM 56 (WCF).

Now we could go with sample of 1 tank to test the calculation.

How to Conduct Bunker Survey

What is Bunker Survey? The survey is carried out to measure and ascertain the quantity of Bunker onboard 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.

Commonly this is done prior to and after a time charter period than mentions as On Hire Bunker (prior) and Off Hire Bunker (after), the Bunker Survey is required to check the amount Bunker transferred or supplied onto the Ship’s Tanks. This job is associated with Ship’s Chief Engineer, the Person who responsible for bunker onboard.
