Estimation and Optimization of Vessel Fuel Consmnption

Vessels with diesel electric power generation enable efficient, and flexible operation of the power plant. In order to make sure that the power plant runs at the optimum operation point, at all times, this paper proposes a method for on-line estimation of the specific fuel consumption of individual generators to enable tracking the true efficiency of each power generation unit, and a method for on-line optimization of the power plant, using the estimated specific fuel consumption. Lased on the results calculated using measured operation profiles from a large cruise ship, fuel savings of 4-6% call he achieved.
