DNV Introduces AROS Framework Creating Clear Pathway for Autonomous Vessel Certification

Classification society DNV introduced the Autonomous and Remotely Operated Ships (AROS) class notations in January 2025, providing a structured framework for the safe development and operation of autonomous shipping technologies and removing a critical regulatory barrier that has prevented widespread commercial deployment of unmanned and remotely controlled vessels. The AROS framework addresses the maritime industry's longstanding challenge of developing autonomous systems without clear certification standards, creating a defined pathway for shipbuilders, technology providers, and operators to achieve class approval while maintaining insurance coverage and port access rights essential for commercial operations. Regulatory gap solution: The maritime industry has been developing autonomous technologies for over a decade, but the absence of clear classification standards created significant commercial risk. Ships require class certification to obtain insurance coverage and port access, yet classification societies lacked frameworks to evaluate autonomous systems against traditional maritime safety standards. DNV's AROS notations fill this gap by establishing specific technical and operational requirements that autonomous vessels must meet, providing objective criteria for safety assessment and creating certainty for companies investing in autonomous shipping technology. This regulatory clarity accelerates investment and deployment decisions that were previously stalled by certification uncertainty. Framework structure: The AROS framework provides structured progression through different levels of autonomy, corresponding to IMO's autonomous ship definitions. Level 2 autonomy, which allows for remotely controlled ships with seafarers on board, now has defined certification pathways that companies like Avikus have successfully navigated for commercial deployment. Higher levels of autonomy—including fully unmanned vessels—can now pursue certification with clear understanding of technical requirements, safety systems, and operational procedures that DNV will evaluate. This tiered approach allows the industry to progressively advance autonomous capabilities while maintaining safety standards appropriate to each autonomy level. Industry validation: The American Bureau of Shipping (ABS) has also approved a pioneering maritime autonomy framework developed by Maritime Technologies Inc. (MTI), demonstrating that multiple classification societies are converging on similar approaches to autonomous ship certification. This parallel development by major classification societies validates the industry's readiness to support autonomous shipping at scale and reduces concern about certification becoming a bottleneck. The frameworks facilitate integration of autonomous systems into maritime operations by providing clear technical guidance, safety requirements, and testing protocols that technology providers can design against from early development stages. Commercial implications: With certification pathways established, autonomous shipping transitions from experimental to commercially viable. Insurance companies can now underwrite autonomous vessel operations based on class certification rather than case-by-case risk assessment. Port authorities gain confidence accepting autonomous vessels certified under recognized frameworks. Technology providers can develop products against defined standards rather than attempting to anticipate future requirements. Most importantly, shipping companies can make investment decisions about autonomous systems with clear understanding of certification costs, timelines, and requirements—removing the regulatory uncertainty that previously made autonomous shipping business cases impossible to justify despite proven technical capabilities and operational benefits.
