DNV, a leading classification society, announced updates to its rules for ships and offshore structures, effective from January 1, 2025, to boost the adoption of decarbonization technologies in the maritime industry. The revisions aim to address the diverse challenges faced by customers, spanning new fuels, operational efficiencies, vessel innovation, and advanced technologies like onboard carbon capture. Notable additions include in-operation class notations that delineate responsibilities between yards and owners/operators, supporting safety and efficiency. DNV also introduced Gas fueled hydrogen and OCCS notations to guide the use of hydrogen as a zero-carbon fuel and onboard carbon capture systems. The updated rules encompass various new class notations such as BOG for boil-off gas systems, live fish transport, stability pontoons for heavy lifts, and hatchcoverless vessels. Additionally, the framework covers floating spaceports, fire safety measures for vessels carrying electric vehicles, and requirements for diving systems aligned with the IMO 2023 code. DNV's initiative signifies a positive step towards sustainability and regulatory compliance in the maritime sector. By offering tailored solutions for emerging challenges like decarbonization and operational efficiency, the updated rules are set to drive innovation and environmental stewardship in shipbuilding and offshore operations.
