Model-Based System Engineering Design Approach for Marine Application

In response to global efforts to combat climate change and achieve emis- sion reduction goals, the maritime industry is undergoing a transformation towards electrification. This shift is driving the development of All-Electric Ships (AES), which are characterized by complex Shipboard Power Systems (SPSs) incorporating Energy Storage Systems (ESSs) with a diverse range of energy carriers. As AES becomes more prevalent, port infrastructure is evolv- ing to accommodate shore connection solutions that enable power transfer be- tween ships and the power grid, with the aim of reducing emissions in coastal areas. This transition towards electrification poses new challenges for ship and port design, with a comprehensive and modular approach. Model-Based System Engineering (MBSE) has emerged as a promising technique for ad- dressing these challenges, providing a digitalized framework for designing marine microgrids. This thesis focuses on the modeling of marine microgrids within the con- text of an MBSE approach, encompassing a wide range of case studies, such as Integrated Power Systems, Platform Supply Vessels, and Naval Shipboard Power Systems, across different design phases. Since the transition towards electrification poses new questions on the ports grid, the approach has been extended to the shore connection infrastructure. In this thesis the port grid has been studied through the use of models, with the goal to integrate these insights into an MBSE approach.
