IMOS - Fuel Grades

On the Data Center menu … > under Vessels > click Fuel Grades.

In the Fuel Grades screen you can specify common fuel blends purchased and used during voyage operations.

The Fuel Grades table supports working with Biofuels, specifically within the Compliance Breakeven Calculation and IMOS - Lifting Level Emissions Workflow.

Below is a guide for the additional fields found in the Fuel Grades table:

In this table, specify common Biofuel blends that may be considered for purchase, for example, B24 and B30. There will be a TtW CO2, WtT CO2eq, TtW CO2eq, and LCV for Product (represents the total lifting value), Fossil component (fossil portion only), and Bio component (biofuel portion only) in this table.

WtT CO2 eq -
- Product - Well to Tank CO2 equivalent emissions per unit of energy for the Fuel Type (gCO2eq/MJ)
- Biofuel - Well to Tank CO2 equivalent emissions per unit of energy for the Biofuel Component of the Fuel Type (gCO2eq/MJ)
- Fossil - Well to Tank CO2 equivalent emissions per unit of energy for the Fossil Component of the Fuel Type (gCO2eq/MJ)
TtW CO2 eq -
- Product - Tank to Wake CO2 equivalent emissions per unit of energy for the Fuel Type (gCO2eq/gFuel)
- Biofuel - Tank to Wake CO2 equivalent emissions per unit of energy for the Biofuel Component of the Fuel Type (gCO2eq/gFuel)
- Fossil - Tank to Wake CO2 equivalent emissions per unit of energy for the Fossil Component of the Fuel Type (gCO2eq/gFuel)
TtW CO2 -
- Product - Tank to Wake CO2 emissions factor for the Fuel Type (gCO2/gFuel)
- Biofuel - Tank to Wake CO2 emissions factor for the Biofuel Component of the Fuel Type (gCO2/gFuel)
- Fossil - Tank to Wake CO2 emissions factor for the Fossil Component of the Fuel Type (gCO2/gFuel)
LCV -
- Product - Lower Calorific Value for the Fuel Type (MJ/g)
- Biofuel - Lower Calorific Value for the Biofuel Component of the Fuel Type (MJ/g)
- Fossil - Lower Calorific Value for the Fossil Component of the Fuel Type (MJ/g)
Bio%
- Percentage of Biofuel for the Fuel Grade
