Sažetak
One of the short-term operational measures for reducing CO2 emission is speed reduction, i.e. slow steaming. In this paper, the benefits of slow steaming approach are investigated on the example of a container ship on typical sailing route for the Mediterranean Sea. Thus, the reduction of fuel consumption and CO2 emission is estimated in calm water and in waves for slow steaming and design speeds. Resistance and propulsion characteristics in calm water are calculated by means of Computational Fluid Dynamics (CFD) based on the viscous flow theory at full-scale. The added resistance in waves is assessed by the potential flow theory. The propeller operating point is estimated for design and slow steaming speeds and sea states with the highest probability of occurrence. Afterwards, the fuel consumption and CO2 emission are calculated. The obtained results provide a valuable contribution to important environmental issue of pollution reduction in the marine protected areas.
