DNV has developed a qualification process for autonomous and remotely operated vessels and systems to ensure an equivalent level of safety as for conventional vessels. This is applied in the new DNV AROS class notations. As the novel technologies and concepts create new and different risks, DNV employs a risk-based verification process, considering human factors and remote operations centers among other aspects, including new verification methods. As technologies mature and experience is gathered, rules and standards will develop and become more detailed and specific. Going forward, collaboration across the maritime industry is essential to achieve the safety objectives for autonomous ships.
