The transition toward LNG, hydrogen, and ammonia propulsion systems represents a transformative shift in maritime decarbonization, introducing new technical, safety, and operational complexities. This study critically examines the effectiveness of Internet of Things (IoT) monitoring systems in enhancing propulsion efficiency, safety assurance, and regulatory compliance within alternative fuel vessels. Using a qualitative comparative design, data were collected from industry experts, maritime lecturers, and maritime graduates through structured thematic analysis. The findings indicate very high overall effectiveness, with safety assurance scoring highest, followed closely by propulsion efficiency and operational compliance. Cross-group analysis reveals strong consensus regarding IoT’s role in real-time leak detection, predictive engine diagnostics, and emission monitoring transparency. The study contributes by bridging propulsion engineering, digital monitoring technologies, and maritime governance perspectives, highlighting the importance of competency development for deck officers in interpreting IoT-generated data. The research demonstrates that IoT systems are foundational enablers of safe, efficient, and sustainable alternative fuel operations, supporting maritime economic resilience and long-term decarbonization strategies.
