The requirements to reduce emissions of carbon dioxide and other greenhouse gases from maritime transport require taking actions aimed at increasing the overall efficiency of the propulsion system, optimal and rational use of electricity and heat. Taking such actions is necessary in order to demonstrate the improvement of the energy efficiency index of a ship in operation or an already existing one (EEOI and EEXI), which will allow to obtain category A or B emissions for a given ship. Obtaining similar energy efficiency effects is also possible after switching to fuels containing less carbon in the molecule and the use of renewable energy. Attempts are made to create new configurations of combined energy systems so as to obtain maximum benefits related to the use of various energy sources in order to ensure the production of energy in quantities consistent with the current demand of the ship in the operating condition.
