Abstract

The article deals with a simulation approach to the representation of the ship motions in waves, interacting with the propulsion system behaviour (diesel engine and propeller). The final goal is the development of a simulator, as complete as possible, that allows the analysis of the main engine thermodynamics in different sea conditions and the correct management of the other propulsion components. This latter aspect is particularly interesting in some of the last new energy solutions for decarbonisation of ships, concerning for example auxiliary electric motors, powered by batteries, to support the traditional diesel mechanical propulsion (especially in heavy weather conditions). From this point of view, a proper analysis of the engine dynamic performance, affected by particular sea states, is fundamental for a smart management and control of shaft generators/auxiliary electric motors, batteries, etc... To this end, the work presents and highlights the main features of a ship simulator, suitable for the study of the new propulsion solutions that are emerging in the maritime transport. Some representative results are also reported to assess the potential of the conceived simulation approach.
