Fully Autonomous Vessel Framework Gets Key Approval

Classification society ABS and Monohakobi Technology Institute (MTI) have successfully collaborated on the development of fully autonomous vessels, receiving approval in principle (AiP) for the maritime autonomy framework. The approval was granted for MTI’s Action Planning and Execution System (APExS-auto), which utilizes the System-Theoretic Process Analysis (STPA) method. This operational framework for fully autonomous vessels was developed by MTI, NYK, and Japan Marine Science Inc. as part of the MEGURI 2040 fully autonomous ship program, with the classification society evaluating it under the ABS Requirements for Autonomous and Remote-Control Functions.

ABS Senior Vice President, Global Engineering Gareth Burton highlighted the importance of the STPA technique for autonomous vessel applications and complex systems found on board fully electric and highly sophisticated ships. MTI Director Hideyuki Ando expressed that the approval from ABS provides a solid foundation for future installations, emphasizing the flexibility of the framework to adapt to operational and design changes. ABS noted that the collaboration with MTI comes at a crucial time as the International Maritime Organization progresses with regulations for Maritime Autonomous Surface Ships (MASS).

The successful application of STPA within the APExS-auto framework represents a significant advancement in realizing the potential of autonomous shipping, according to ABS. This collaboration between ABS and MTI demonstrates forward-thinking approaches in supporting clients and integrating advanced systems in autonomous functions within the maritime industry. The approval from ABS marks a milestone in the development of autonomous vessels and aligns with ongoing efforts to establish regulations for Maritime Autonomous Surface Ships.
