Regulation (EU) 2023/1805 of the European Parliament and of the Council of 13 September 2023 on the use of renewable and low-carbon fuels in maritime transport, and amending Directive 2009/16/EC (Text with EEA relevance) article annex_V CELEX: 32023R1805 Calculation of adjusted mass of fuel for ice navigation
This Annex describes how to calculate:
— the additional energy consumption due to technical characteristics of a ship having the ice class IA or IA Super or an equivalent ice class
— the additional energy consumption of a ship having the ice class IC, IB, IA or IA Super or an equivalent ice class due to sailing in ice conditions
— the adjusted mass [Mi A] after the deduction of the additional energy, allocated to each fuel i
Additional energy due to ice class
The additional energy consumption due to the technical characteristics of a ship having the ice class IA or IA Super or an equivalent ice class is calculated as follows:
Where:
Evoyages, total denotes the total energy consumed for all voyages and; Eadditional due to ice conditions denotes the additional energy consumption due to sailing in ice conditions.
The total energy consumed for all voyages is calculated as follows:
Where:
Mi, voyages, total denotes the mass of fuel i consumed for all voyages within the scope of this Regulation and; LCVi the lower calorific value of fuel i.
Additional energy due to sailing in ice conditions |
Regulation (EU) 2023/1805 of the European Parliament and of the Council of 13 September 2023 on the use of renewable and low-carbon fuels in maritime transport, and amending Directive 2009/16/EC (Text with EEA relevance) article annex_V CELEX: 32023R1805 The additional energy consumption of a ship having the ice class IC, IB, IA or IA Super or an equivalent ice class due to sailing in ice conditions is calculated as follows:
Where:
Evoyages,open water denotes the energy consumed on voyages in open water and; Evoyages,ice conditions, adjusted denotes the adjusted energy consumed in ice conditions. Eadditional due to ice conditions cannot be higher than
The energy consumed for voyages that include sailing in open water only is calculated as follows:
Where:
Evoyages,ice conditions denotes energy consumed for sailing in ice conditions, which is calculated as follows:
Where:
Mi,voyages,ice conditions denotes the mass of fuel i consumed for sailing in ice conditions, within the scope of this Regulation.
The adjusted energy consumed in ice conditions is calculated as follows:
Where:
Dice conditions denotes the aggregated distance travelled when sailing in ice conditions within the scope of this Regulation. is the energy consumption per distance travelled in open water calculated as follows:

Total additional ice energy due to ice class and sailing in ice conditions
Adjusted mass [Mi,A]
The company shall allocate the total additional ice energy E i additional ice to the different fuels i used during the year, with the following conditions:
Σ E i additional ice = E additional ice
For each fuel i,
The [Mi,A] adjusted mass of fuel is calculated as follows: |
