Ship Trim Optimization for the Reduction of Fuel Consumption

Greenhouse gas emissions and atmospheric pollutants, economic savings, as well as alignment with the new rules of the shipping industry's leading is a new concern. In order to meet and achieve these goals, many efforts have been made. In this paper, some methods for reducing fuel consumption, including optimization of floating trim, have been considered in design draught. In this regard, the body resistance of model of the KCS container ship is calculated in design draught; This analysis was performed by numerical solution and experimental test for -0.1 to +0.1 trim range. And the results of ship model analysis was generalized to the main body. In this regard, the mathematical model of ship propulsion system is implemented in the MATLAB-Simulink software; and by using this model for different trims, rates of ship specific fuel consumption presented. According to the results of modeling and simulation of the floating body, a reduction of 1.5% of fuel consumption has been achieved due to optimization of the trim.
