DNV updates seismic design guidance as wind expands into earthquake-prone regions. DNV has published an updated edition of its recommended practice DNV-RP-0585 Seismic design of wind power plants, providing enhanced guidance for the design of onshore and offshore wind assets exposed to earthquake loading. As wind power deployment expands into seismically active markets, particularly across Asia-Pacific, earthquake loading is increasingly becoming a key design consideration. Seismic events can significantly affect wind turbines, foundations, offshore substations, power cables and installation vessels, creating engineering challenges beyond those addressed by conventional wind and wave design approaches. The updated recommended practice provides harmonized guidance for assessing and managing seismic risks throughout the design process. It complements existing DNV standards for wind turbines, support structures and offshore substations, while supporting projects designed in accordance with the IEC 61400 series. "Wind power projects are increasingly being developed in regions where earthquake loading is a primary design driver rather than a secondary consideration," says Mette Redanz, Vice President for Renewables Certification at DNV. "The updated recommended practice provides the industry with consistent and transparent methodologies for seismic design, enabling safer and more reliable wind power projects in some of the world's most demanding environments." The 2026 edition incorporates lessons learned from recent projects and from the ACE 2-EVOLUTION joint industry project (JIP), which brings together more than 20 companies from across the offshore wind value chain. Key updates in the new edition include: * Enhanced guidance on seismic analysis methodologies and modelling requirements * Updated recommendations for soil-structure interaction and foundation damping * Clarifications on seismic loading, ground motion selection and post-processing requirements * Guidance for identifying critical design positions within large wind power plants * New recommendations for installation vessels operating in seismic regions * An informative appendix summarizing local seismic design requirements in Japan "Effective seismic design requires close alignment between turbine, foundation and geotechnical disciplines," explains Marcus Klose, Project manager for the ACE joint industry project and Head of Section Offshore Technology and Innovation at DNV. "This update reflects insights gained through international collaboration and practical project experience, providing engineers with clearer guidance while supporting consistency and confidence across the industry." Applicable to both onshore and offshore projects, DNV-RP-0585 provides guidance on seismic hazard assessment, design load cases, geotechnical considerations, analysis methods and post-earthquake actions. The recommended practice supports designers, developers, suppliers, purchasers, regulators and certification bodies involved in wind projects in seismically active regions worldwide.

DNV launches first standardized framework for onboard carbon capture. June 22, 2026 Classification society DNV has published a landmark recommended practice (RP) establishing a standardized framework to measure and verify the performance of onboard carbon capture and storage (OCCS) systems. The new guideline, DNV-RP-0698, arrives as the maritime industry searches for immediate decarbonization solutions, providing a critical technical foundation for the scaling of onboard captured carbon technologies. With roughly 90% of the global operational fleet still entirely dependent on conventional fossil fuels, OCCS is rapidly emerging as a vital transitional pathway. It offers a practical emission-reduction strategy for existing vessels that cannot easily or economically retrofitted to run on low-greenhouse gas fuels. This industry push is mirrored on the regulatory front, where the International Maritime Organization (IMO) has already initiated development on formal OCCS guidelines, targeted for completion by 2028. Establishing a shared technical language for maritime CCS. Built around rigorous mass balance principles, the DNV framework defines a harmonized set of key performance metrics. These include absolute capture rates, the specific quantity of captured CO2, remaining atmospheric emissions, and gross capture efficiency. Crucially, the framework remains entirely technology-neutral, accommodating pre-combustion, post-combustion, oxy-fuel, and alternative capture architectures. To ensure market trust, the RP introduces a structured, third-party verification process. This protocol encompasses comprehensive system documentation, measurement setup evaluation, performance calculations, and strict uncertainty assessments. According to DNV, establishing this shared technical language is essential for mitigating investment risks early in the design phase. The initiative highlights a growing reality for the maritime sector: long vessel lifespans mean the existing fleet requires immediate, bolt-on environmental solutions. By providing a clear methodology to account for the full performance picture, rather than just raw capture volumes, the new practice enables shipyards, manufacturers, and shipowners to make highly informed deployment decisions for both newbuild and retrofit projects worldwide.

DNV has made a strategic minority investment in Vind AI through DNV Ventures and will take an observer seat on the company's board. The investment supports Vind AI's platform development and international expansion. Vind AI operates a digital platform for renewable energy project development. As part of the deal, DNV's CFD-ML wind modelling technology will be integrated directly into the Vind AI platform. The funding round included participation from existing investors Norrsken VC and Arkwright X, plus Vind AI employees, who retain approximately 70% ownership as the largest shareholder group. Vind AI will continue operating independently and collaborating with data and technology partners across the sector.
