外文摘要：Due to fuel price fluctuations and greenhouse gas emissions caused by international shipping, the reduction of ship fuel consumption is important. In this paper, a ship energy consumption prediction model is established based on the BP neural network optimized by the Levenberg-Marquardt (LM) algorithm to predict ship energy consumption. Firstly, the ship navigation data are analyzed. Ship speed, draught and current speed are selected as the main factors affecting ship energy consumption and their weights are determined by the spearman and regression analysis. Then, the ship energy consumption model is established based on the LM-BP algorithm. Finally, ship speed, draught and current velocity are used as the input and ship energy consumption is considered as output for the model to validate the model. The predicted results is compared with the real energy comsumption and the final RMSE is approximately 259.74 kW. For ships sailing with power ranging from 6000 kW to 8500 kW, the model prediction error is 3.06 %. The results of this study could be used to optimize ship operational plans to improve the economics of waterway transport.
