To enhance the design and verification level of marine power system and address the issues of high verification costs and difficulties in debugging complex fluid conveyance designs, this paper proposes a system architecture model design method based on Model-Based Systems Engineering (MBSE). The research follows the MBSE design philosophy and the RFLP modeling methodology, utilizing domestic modeling platforms such as M-Design, and combines SysML and Modelica languages to establish the architecture of complex fluid conveyance systems for ships. This architecture includes modules such as requirement analysis, functional analysis, logical architecture, physical model, and interfaces. It comprehensively covers the needs of fluid users and internal and external environments, allowing for rapid verification of key indicators. It drives the deepening of physical models for co-simulation before physical debugging, completes the calculation and verification of system tuning strategies in the virtual space ahead of time, and verifies fluid conveyance flow distribution technology and operational plans. The study demonstrates that the architecture design of fluid conveyance systems based on MBSE is scientific, efficient, and strongly traceable, necessitating further promotion in the design of marine power systems.
