“…Most of this consumed energy is invested in overcoming i) the inertia to the motion and ii) the resistance exerted by the external forces acting on the vehicle. In the case of boats, the reaction exerted by the water must be overcome, while the boat is moving at a defined speed (Giraldo-Pérez et al, 2020). When designing a vessel, cruising speed and the demand for cargo and/or passenger transport capacity are taken as a starting point to dimension and define the shape of the hull, which must allow to act safely and stably in the different static and dynamic situations.…”

“…The context of use and design requirements were analyzed in Mira et al (2020b). From those requirements and a conceptual design phase (Giraldo- Pérez et al, 2020;Giraldo Pérez et al, 2021), the general parameters of the boat, which will be a Catamaran with Outboard architecture, as well as a energy storage unit (composed of NCM-type lithium battery cells) are presented in Table 4.1.…”

“…With these alternatives, what is the most suitable design combination to improve PS's efficiencies?. The starting point is to know: i) the hydrodynamic resistance (extracted by Savitsky's method (Savitsky et al, 1964;Giraldo-Pérez et al, 2020)), and ii) the electric motors' power and efficiency curves. With this information, the methodology proposed in this work (See Sec.…”

“…An estimation of the hydrodynamic resistance of the vessel is performed by implementing the method presented in Giraldo- Pérez et al (2020). This method is based on the statistical model of resistance estimation proposed by Savitsky et al (1964) with the vessel parameters presented in Table 4.1.…”

Boats have historically been an important mean of transportation, both for passengers and cargo, mainly in water-rich countries. Today, the electrification of transportation includes fluvial navigation, but energy efficiency remains a key issue. Energy consumption, in electrically powered vessels, is strongly influenced by several technical systems (e.g. hydrodynamics, battery, propulsion, etc.). While advances in some of those main systems are found in the literature, this research work focuses on the design and optimization of the "propulsion system (PS)" (Motor-Transmission-Propeller). By implementing an electric motor, the interaction of the mechanical components can be analyzed to find the optimal variables that will govern the performance of the vessel and that allow the optimal Motor-Transmission-Propeller combination. This manuscript presents the development of a multivariable optimization methodology to maximize the overall efficiency of a propulsion system and, therefore, the autonomy of an electrically powered river vessel. The methodology starts with the analysis of the physical variables that define the performance of the propulsion unit components, and establish an optimality problem and an exhaustive search model that considers all possible values of the key design parameters. A case study is presented for the design of an electrically powered river boat, for the transport of people, within the framework of the ENERGETICA 2030 project. This methodology enabled the choice of the PS's components, while optimizing the energy consumption.
