RESEARCH ON EEOI PARAMETRIC CONNECTION OF A SHIP DURING THE REAL VOYAGE CONDUCTION

open access: yesRussian Journal of Water Transport, 2020
The round-the-world transition of m/v Katherine ship is considered. The aim of this work is to minimize the Energy Efficiency Operational Indicator (EEOI) of the vessel, and, accordingly, to minimize the ship's fuel consumption and carbon dioxide emission depending on the parameters of sea transition: Vs, mass of transported cargo, and the distance of ...
