Hello all,

There is a point that I canβt find solution for the CII Correction Factors and more specifically for the FCelectrical for Reefer Container ships.

For those that do not remember the Regulation by heart:

For ships equipped with reefer electrical consumption monitoring, they can calculate reefer container kWh. However, for ships without this capability, the calculation for reefer kWh consumption is as follows:

Where:

- πΆπ₯ represents the default reefer consumption of 2.75 kW.
- π πππππ_πππ¦π π ππ & π πππππ_πππ¦π πππt represent the number of in-use reefer-days over the declared period.
- ππΉππΆππ£π represents the specific fuel consumption in g/kWh. It is a weighted average of the engines used to provide electrical power, as specified in the EEDI/EEXI Technical File or NOx Technical File. If your ship does not have a Technical File, you can use default values of 175 g/kWh for 2-stroke engines and 200 g/kWh for 4-stroke engines.

My question is about the fuel deduction (*FCelectrical_reefer*) when using a Main Engine shaft generator with Heavy Fuel Oil (HFO) and Auxiliary engines with Marine Gas/Diesel Oil (MGO/MDO), where the formula calculates the Fuel Deduction based on ππΉππΆππ£π.

How can I calculate how much mass of HFO and MGO/MDO (that can be translated into grams of CO2) I can deduct from the formula for my ship?
