How are Bunker Consumption and Cost Calculated?

Consumption

Fuel Oil

• FO ballast * days ballast
• + FO loaded * days loaded
• + FO in port working * days loading in ports tagged as working
• + FO in port idle * days loading in ports tagged as non-working
• + FO in port idle * days waiting
• + FO in port idle * days extra in port
• + FO in port working * days discharging
• + FO in port idle * days canal
• + FO cleaning * days cleaning
• + FO heating * days heating  

Diesel Oil

• DO at sea * days ballast
• + DO at sea * days loaded
• + DO in port working * days loading in ports tagged as working
• + DO in port idle * days loading in ports tagged as non-working
• + DO in port idle * days waiting
• + DO in port idle * days extra in port
• + DO in port working * days discharging
• + DO in port idle * days canal 

Cost

• Cost for each bunker type is simply calculated as total consumption * estimated price

Consumption

The consumption for each bunker type is calculated like an estimate. However, as actual ROBs are keyed in at arrival and departure, the VMS will use a combination of estimates and actual consumption based on the ROB figures. Once all ROB figures are entered the VMS will ONLY uses the ROB figures to calculate the consumption. 

Cost

• All Bunker Types: 
  • Total consumption * actual price based on FIFO
  • - total offhire consumption deductible owner * agreed price
  • +/- loss / profit on bunkers against owner

Consumption

Fuel Oil

• FO ballast * days ballast (prior to delivery/after redelivery)
• + FO in port idle * days total in port (prior to delivery/after redelivery)  
• + FO in port idle * days canal (prior to delivery/after redelivery)

Diesel Oil

• DO consumption = DO at sea * days ballast (prior to delivery/after redelivery)
• + DO in port idle * days total in port (prior to delivery/after redelivery)
• + DO in port idle * days canal
