Speeding optimization considering the fuel consumption in the mooring period

Abstract

This paper aims to establish a nonlinear speeding optimizing model for minimizing the fuel consumption. Considering the fuel consumption of the vessel both in sailing and mooring, the traditional speeding optimizing model with fuel consumption only in sailing consideration is improved. Not only the relationship between fuel consumption and speed in sailing is fitted by a power function, but also a linear function was used to fit the relationship between fuel consumption and time in mooring. Based on the two functions above, a new speeding calculating formula which is more practical is proposed. The simulation experiments prove the speeding optimizing model and formula proposed can reduce the fuel consumption and emission more effectively.
