DNV Launches New Class Notations for Autonomous Ships

Norway-based classification society DNV has introduced a groundbreaking family of class notations designed to ensure the safety of remote/autonomous ships, surpassing that of conventional vessels.

The Autonomous and Remotely Operated Ships (AROS) notations, launched in December 2024 and made available since January 1, 2025, provide a comprehensive framework covering navigation, engineering, operational, and safety functions for autonomous vessels. The classification system aims to categorize autonomous ships based on their level of autonomy and control location.

DNV’s AROS notations offer the maritime industry a structured approach to the development of autonomous shipping technologies. Collaboration with flag and coastal states is emphasized to ensure approval and compliance with regulatory standards.

Autonomous shipping presents numerous advantages, including enhanced safety, improved logistics, increased cargo capacity, fuel efficiency, emission reduction, and cost savings. However, challenges such as cybersecurity vulnerabilities in autonomous operations have also been highlighted by industry experts.

The International Maritime Organization (IMO) and other regulatory bodies are working on cybersecurity requirements, with the IMO developing a Maritime Autonomous Surface Ships (MASS) code. DNV’s AROS definitions align with the MASS code’s objectives, aiming to enhance safety and reliability in autonomous operations.

Geir Dugstad, Technical Director, Classification at DNV Maritime, emphasized the importance of autonomous shipping in the industry’s future development. The AROS notations build on DNV’s existing guidelines for autonomous vessels, offering flexibility for innovation while maintaining safety standards.

Recent advancements in autonomous shipping include ABS approving a fully autonomous ship framework developed by Japanese companies in the MEGURI 2040 program. BIMCO also introduced the AUTOSHIPMAN agreement to support the operation of remote-controlled and autonomous vessels.

Overall, DNV’s new class notations for autonomous ships signify a significant step towards the safe and efficient implementation of autonomous technologies in the maritime industry.
