MVS： CMm=CMa×Tm/Ta
ASVS： CMa
- Insurance costs; costs are charged per year (CIa). In one voyage simulation, multiply CIa by the ratio of voyage days(Tm) to operation days per year(Ta).
MVS：CLm=CIa×Tm/Ta
ASVS ： CIa
Escort costs： costs related to icebreaker escort, icebreaker fees(Tariff) and ice pilot fees are considered.
‐Tariff； calculate to every one voyage(CTRv).
MVS： CTRm, it is CTRv in m-month of certain year.
ASVS： CTRa=ΣjCTRj
where, CTRj is tariff of voyage for the j-time of voyage.
‐Ice pilot fee; depends on the navigation days in the NSR. Multiply ice pilot charge par day(CIPd) by the navigation days(Te).
MVS： CIPm=CIPd×Te
ASVS： CIPa=ΣjCIPj
where, CIPj is ice pilot fee for the j-time of voyage.
Fuel costs： fuel consumption at a route segment(QFi) is calculated by multiplying a fuel consumption rate by a voyage time and a required power froml speed-power curve, which meets the ice condition of a segment. Costs for one voyage(CFv) are estimated by multiplying the entire fuel consumption totaling the QFi over the route by a bunker price(cf).
CFv=cf×ΣiQFi, QFi is fuel consumption for I-segment
MVS： CFm, it is CFv for m-month of certain year
ASVS： CFa=ΣjCFj, CFj is CFv for the j-time of voyage.
Port costs： a different port cost(CP) is required at every stop of port to use of equipment and so on. For one voyage simulation, a cost(CPDi) related to loading and preparing departure at departure port(i-port),a cost(CPAj) at arrival port (j-port) related to entering port and unloading are considered.
MVS： CPm=CPDi+CPAj
ASVS： CPa=Σk(CPDik+CPAjk)
where, CPDik is CPD at departure port of the k-time of voyage.
CPAjk is CPA at arival port of the k-time of voyage.
