The Economic and Regulatory Challenges of Implementing Digital Twins and Autonomous Vessels in U.S. Maritime Fleet Modernization

The modernization of the U.S. maritime fleet is crucial to maintaining competitiveness in an evolving global landscape. This review examines the economic and regulatory challenges of implementing digital twins and autonomous vessels within this sector. Digital twins provide a virtual replica of vessels, enabling real-time monitoring, predictive maintenance, and operational efficiency, while autonomous vessels promise cost savings and enhanced safety by minimizing human error. However, adopting these technologies poses significant challenges, including high initial investment, integration with legacy systems, and regulatory gaps. This paper discusses the current limitations within U.S. regulatory frameworks, economic impacts, and international standards that impact fleet modernization efforts. It further discusses collaborative approaches to overcome funding and technical barriers, emphasizing the need for dynamic, adaptive regulations to balance innovation with safety and compliance in an increasingly automated maritime industry.
