Abstract. Energy storage has the potential to reduce the fuel consumption of ships by loading the engine (s) more efficiently. The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy. Previous research in this area consists of detailed

Hybrid (or all-electric) ships that consider multiple forms of energy storage and clean energy have the potential of energy saving which have been widely studied. Energy management as a key technology for coordinating the efficient working of all energy sources on board ships has become a focus of research.

Considering the ship design process, if high energy efficiency is one of the goals for the project, one of the most important issues is to start early. In practice, this means that the ship energy modeling and KPI-follow up process should be started already at early conceptual design stage, as indicated in Fig. 12.1.
