ANNEX V
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: Eadditional due to ice class ¼ 0; 05×ðEvoyages;total – Eadditional due to ice conditions Þ 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: Evoyages;total ¼ ∑Mi;voyages;total ×LCVi 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 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: Eadditional due to ice conditions ¼ Evoyages;total – Evoyages;open water – Evoyages;ice conditions;adjusted 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 1; 3×Evoyages;open water
The energy consumed for voyages that include sailing in open water only is calculated as follows: Evoyages; open water ¼ Evoyages;total – Evoyages;ice conditions Where: Evoyages,ice conditions
denotes energy consumed for sailing in ice conditions, which is calculated as follows: Evoyages;ice conditions ¼ ∑Mi;voyages;ice conditions ×LCVi
