Global assessment of shipping emissions in 2015 on a high spatial and temporal resolution

Model for Estimation of Fuel Consumption of Cruise Ships

“…Boiler tonnes−pr−minute = Boiler tonnes−pr−hour 60 (27) Fuel consumption for boilers over a given time span is then found by calculating consumption per minute shown in Equation (27) and multiplying by number of minutes from Equations (1) and (2). Fuel for boiler consumption is added to fuel for hotel functions for non diesel-eletric ships in port.…”

“…Fuel consumption per minute is multiplied by the number of minutes found in Equations (1) and (2). Equation (24) …”

“…A linear interpolation according to Equation (9) is implemented where the symbol TS is the target speed at interpolation end point, BS is the base speed at the interpolation start point, t is the number of minutes from interpolation start point, S t is interpolated speed at time t and totMin are minutes taken from calculations above in Equation (1) or Equation (2). The linear interpolation is defined as follows:…”

“…This factor represents the expected increase (or decrease) for every minute. The number of minutes is calculated as described above in Equations (1) and (2). Interpolation factor for exponential interpolation is defined as follows:…”

“…The most recent model suggests emissions of 831 Mt CO2 in 2015 [2]. The shipping sector is projected to grow by 50-250% by 2050 [1], where emissions from all other sectors except aviation are expected to fall under the Paris Agreement.…”
