Co-simulation enhances the efficient simulation development even for complex systems reducing time to market and computational effort. This work aims to develop a marine hybrid power system simulator using a co-simulation approach. The subsystems are packed as Functional mock-up units (FMUs) with the standard interface called functional mock-up interface (FMI). The FMUs for major subsystems are generated from the previously developed dynamic system model. However, FMUs developed by the partners are also compatible for the implementation. These FMUs are implemented in an open simulation platform's (OSP's) software Kopl and Co-Sim App to develop a system simulator. The use of a co-simulation framework for realtime virtual testing and various model fidelity implementation is studied. The developed simulator is used for testing the functionalities and operational capabilities of the studied system. It can simulate faster than real-time, thereby enhancing its use for real-time virtual testing applications. Implementing various fidelity FMUs enhances modularity. It also increases the flexibility in an FMU selection based on the simulation objectives, accuracy, and computational effort.
