SAŽETAK /ABSTRACT:

Environmental concerns and pollution reduction are common research topics. In line with this trend, most members of the Department of Marine Engineering at the Maritime Faculty in Split are involved in the EnEMar (Energy Efficiency and Reduction of Harmful Gas Emissions in Maritime Transport) project, which investigates and compares measures for the decarbonisation of maritime transport. As a result of this research, greater emphasis is placed in classes on demonstrating these measures and their effects, initially through conventional teaching and then using an engine-room simulator. This paper describes the use of a simulator exercise to show students the effect of reduced engine load and ship speed on fuel consumption and emissions, as well as the behaviour of the carbon footprint at different loads of a ship’s propulsion system. Despite the sophisticated term, optimisation in this context simply means reducing the ship’s speed, that is, reducing fuel consumption. Students first learn in theory that a ship’s speed and power are related cubically, and this relationship is then demonstrated on the simulator, where they can observe and calculate, in virtual reality, the exact effect of speed “optimisation” and its consequences.
