摘要:In recent years,there has been a significant development in “green” and energy efficient propulsion systems,which fits into the general trend of environmentally friendly “green shipping”.The pursued goal is to construct a safe passenger ship that is low in energy demand and equipped with a highly energy efficient,emission-free propulsion system.The paper presents main problems encountered by designers of a small,hybrid-powered ferry powered lithium batteries.The conducted research allowed to create a design of an energy efficient hull shape,which decreases the demand for energy.Completed remote control model tests resulted in a proposal of an energy efficient and safe propulsion system with good manoeuvring capabilities.Measurements completed on an existing ferry permitted completing energy balance and forming an energy management policy.The paper contains the emission calculations computed for the existing ferry that are necessary for the environmental impact analysis.The soon to be constructed,newly designed vessel will provide a valuable contribution to hybrid-propulsion,energy management and unmanned technologies research.
