“…Therefore, the authors propose to use hybrid propulsion with a hybrid power supply, to replace the mechanical propulsion with a PTO to generate auxiliary power. For a small coastal research vessel [49], the mission consists of maneuvering with low speed in waters with a small water depth, or navigating at open sea, which results in a power profile with high loads for high vessel speeds, and low loads for low vessel speeds. The vessel is required to have zero-emission modes, so the power plant of this vessel supports hybrid propulsion and a hybrid power supply.…”

Dear reader,This thesis is the last step towards completing my Master of Science in Mechanical Engineering at the University of Technology in Delft. It has been quite the journey, which started with the track Multi-Machine Engineering. During the second year of my masters, I did a literature study under the supervision of Vasso Reppa and Nikos Kougiatsos, where I reviewed the state-of-the-art of the propulsion control in marine vessels. I found that, although there is a great variety in propulsion control systems, no literature considered modular use of the equipment in the power plant. To this end, in collaboration with Vasso, Nikos, and Royal IHC, the main idea for this thesis was proposed.Soon after the initial proposal the main course of the thesis was set, and after the approval of Rudy Negenborn, the journey began. In this work, you may find information about different missions of ships, how these missions dictate the required power, and also how this affects the power plants and the control systems found in various marine vessels. It is shown how this leads to a mission-oriented design of the control system, where equipment can be added, replaced, or removed. Although I did not specialize in control engineering, my skills with MATLAB, developed during the master, greatly helped to resolve most problems, and I am proud to present you my work.I want to start by thanking Vasso and Nikos for their daily supervision and assistance. Nikos is a PhD researcher, and his field of work is very closely related to the topic of this thesis, so he was always able to provide insightful comments and detailed explanations when I found some obstacles. Vasso's input was aimed more towards the presentation and design of the control systems, and was also very helpful with maintaining the right course, and keeping track of the main goal of the thesis. Also, I want to thank Rudy, who was able to provide good feedback during meetings, as he knows a great deal about this topic, and a lot of his work is used in this thesis.Finally, I want to thank my parents, friends and my girlfriend for their support, motivation, and guidance, not only during this thesis, but also during my entire studies at the TU Delft. This journey would not have been the same without you. I wish you a pleasant reading,

“…Ferries are also analyzed, but only the authors of [33,107] provided useful data. Research vessels also have been found, and limited information for the power requirements for each operational mode is provided by [49], but no useful data for a clear division between propulsion power and auxiliary power has been found.…”

“…Often, especially during measurements, the ship is required to follow strictly a predefined route. Hence, research vessels are usually equipped with DGPS devices and dynamic positioning systems [8]. Moreover, during research activities requiring the adoption of hydrophones or other acoustic devices, it is required to limit the noise emission from the propulsion system.…”

Nowadays specific ships are used to train students as sailors. As historical vessels are conveniently employed to this aim, the average age of these ships is usually high. In order to amortize operating and maintenance costs, the training ships' ownership (except for naval ones) is shared among multiple entities and schools. Moreover, generally these vessels are used in coastal navigation. The consequent operational profile imposes the need to rearrange the ship internal spaces according to the shipowner who will use it. Considering all these reasons, a modular design approach can be adopted in the refitting process, while reverse engineering techniques and integrated design tools should be used for the reconstruction when the original technical documentation is not available. In this context, hybrid-electric propulsion systems can be proposed as effective to enable the Zero Emission Mode, thus reducing the vessel's environmental impact during the training. By doing this, three goals are achieved to extend the ship operational life: ease of rearrangement of the internal spaces for different uses, reduction of operating/maintenance costs and eco-sustainability in coastal navigation. In this paper, after a description about modular design and hybrid electric technologies, the refitting project of the M/N "Umberto d'Ancona" is discussed. The latter is the training ship of "Tomaso di Savoia Duke of Genoa", the nautical institute in Trieste, Italy.

“…The second option is to install onboard equipment dedicated to the exhaust gas treatment. The third option is to rely on the vessel's electrification [9][10][11][12]. In this context, the INTERREG project METRO (Maritime Environment-friendly TRanspOrt systems) analyzes innovative solutions to improve the North Adriatic maritime transport environmental sustainability.…”

The increasing sensibility to the environment protection and emission reduction in the atmosphere is also influencing the maritime shipping. The more restrictive regulations on pollutants suggest the adoption of alternative onboard propulsion and energy generation systems. To this end, electrification is a promising solution for pollution reduction, giving some flexibility on the strategy to use for the onboard system. Moreover, a hybrid-electric system can be combined with the exploitation of green fuel, increasing the potential reduction of total emissions. However, the final efficiency, both in term of emission reduction and expected operative expenditure, is strongly influenced by the operative profile of the vessel. This is of utmost importance both in case of a newly designed vessel and in the retrofitting of an existing one. In the present work, the impact of electrification on a double-ended ferry is presented, taking into consideration the operative profile of the vessel derived from real navigation data.
