Goals and competencies

Objectives: The fundamental goal of this course is to acquaint the students with the entire spectra of energy conversion and energy use in maritime applications with a special emphasis on energy conversion and energy storage devices in vessel’s power-plants. Reaching this objective relies on the knowledge of processes and characteristics of these devices, which enables understanding operating principles and optimisation of integrated propulsion systems on vessels and optimisation on the larger scale of energy use in maritime transport.   

Competences: Students will acquire systematic and logic knowledge on all relevant scale ranging from nano-sale phenomena in specific devices over macro-scale understanding of operating principles and characteristics of devices up to the knowledge of integrated systems on the system level. These competences will enable autonomous evaluation of processes and topologies of propulsion systems with respect to their characteristics and environmental as well as energy efficiency constraints. Additionally, students will be capable of using basic knowledge to design and optimise processes in real systems and they will also be capable of evaluating the influence of the individual processes and technological improvements on performance of the propulsion system. Broad knowledge basis, which also includes emerging technologies, will equip students with future proof knowledge and therefore enable them to competently evaluate these future trends.
