“…This approach is flexible for adjustments to other system-level cases. Abrougui et al [15] used MATLAB/Simulink to solve the ordinary differential equations for the propulsion components of an electric boat. The equations of the electrical machine were simplified, and it was demonstrated fast and accurately that there was no overshooting in ship's forward speed and electric motor's rotational speed.…”

This paper presents a comprehensive literature review of the state-of-the art modeling and optimization methods for the power and propulsion systems of ships. Modeling is a tool to investigate the performance of actual systems by running simulations in the virtual world. There are two main approaches in modeling: physics-based and data-driven, which are both covered in detail in this survey paper. The output from the simulations might not be optimal in terms of certain performance criteria such as energy consumption, fuel cost etc. Hence, it is vital to optimize the systems considering the efficient interaction between the components, to yield the optimal performance for the integrated vessel's powertrain. In this paper, the optimization case studies, for the ship energy systems, will be divided in terms of a) optimal design (topology and sizing), b) optimal control and energy management strategies, c) combined optimal design and control. Tables that summarize the literature review outcomes will also be presented at the end of each section. The main outcome is that limited literature is available for optimizations of ship powertrains using datadriven models, especially surrogate models. Surrogate-assisted optimizations for integrated ship energy systems can yield optimal solutions at fast computational speeds, with sufficient accuracy, even for complex, nested, multi-level, multi-objective optimizations.

“…The most interesting approach is to considerer both dynamics and propose constitutive equations for guaranteeing a robust coupling on the model. Some modeled systems with this approach include coupling among synchronous machine, propeller, and hull [7] and coupling between mobile propulsor and the ship dynamics [5]. However, the current models do not include couplings between the hull dynamics and propulsion system based on brushless direct current motors (BLDC).…”

The objective of this research is to provide a tool that allows to quantify the power requirements, energy consumption and the efficiency of the propulsion system of a catamaran with two degrees of freedom according to its speed. Furthermore, it seeks to improve the design process from a phenomenological perspective that gives rise to a better reliability of the result. To achieve this, an electromechanical model is being developed by using the methodology for obtaining phenomenological-based semi-physical models. This model couples the dynamics of a geometry-known ship with its propulsion system, which is constituted by a propeller and a brushless direct current (BLDC) electric motor; at the same time, it uses data from computational simulations related to the hydrodynamics of the submerged components. Finally, the results of using the model with parameters of a specific catamaran and motor are presented. This model allows to properly couple the dynamics of a boat with two degrees of freedom.
