Evaluation of the energy consumption of container diesel trucks in a container terminal: A case study at Klaipeda port

Abstract

Introduction: In the paper, we examine the energy consumption efficiency of specialized con tainer diesel trucks engaged in container transportation at a seaport terminal. Objectives: Using the container terminal at Klaipeda in Lithuania as the background for the research, _ we produced an improved energy consumption model for measuring the theoretical energy consump tion and regeneration of diesel trucks at the terminal and provide a comparative analysis. Methods: We created a mathematical model which describes the instantaneous energy con sumption of the diesel trucks, taking into account their dynamic properties and the overall geome try of their routes—‘‘Ship-Truck-Stack-Ship’’—using the superposition principle. We investigated other critical parameters relevant to the model and provide a statistical evaluation of the transpor tation process using data from a case study of Klaipeda port, where we collected measurements _ of container transportation parameters using georeferenced movement detection and logs from wireless equipment positioned on the diesel-powered container trucks. Results: The modeling results showed that an instantaneous evaluation of energy consumption can reveal areas in the container transportation process which have the highest energy loss and require the introduction of new management and process control initiatives to address the regu lations which are designed to decrease harmful industrial emissions and encourage novel technol ogies and thereby increase the eco-friendliness of existing systems.
