DNV revisa prática recomendada para projeto sísmico de eólicas offshore
Atualização do DNV-RP-0585 reflete a expansão da eólica offshore para regiões sismicamente ativas — um tema ainda periférico para o Brasil, mas relevante para o setor globalmente.
THE NEWS
According to Marine Technology News, the classification society DNV has updated its recommended practice for the seismic design of onshore and offshore wind power plants. The revision to DNV-RP-0585 introduces enhanced guidance aimed at addressing the engineering challenges that arise as wind energy development expands into earthquake-prone regions.
The update responds to a structural shift in where wind projects are being developed. As the most accessible sites in seismically stable areas are progressively occupied, developers are moving into territories where seismic loading must be treated as a primary design consideration rather than a secondary one.
DNV's recommended practices, while not mandatory regulations, function as de facto technical benchmarks across the offshore energy sector. Updates of this nature typically influence procurement specifications, lender requirements, and certification pathways for projects worldwide.
WHY IT MATTERS
For readers focused exclusively on Brazil's offshore oil and gas sector, the immediate operational relevance of this update is limited. Brazil's offshore wind development is still in early stages, and the country's Atlantic coastline — where offshore wind concessions are being assessed — does not present the same seismic risk profile as, for example, the Pacific Rim or parts of the Mediterranean. On that narrow reading, DNV-RP-0585 is a document to file rather than act on today.
However, the update carries a broader signal worth tracking: classification societies are actively building the technical infrastructure for offshore wind at scale. DNV's decision to invest in seismic-specific guidance reflects the pace at which offshore wind is maturing as an engineered discipline — one that is now complex enough to warrant the same granular recommended-practice architecture that governs floating production systems, mooring integrity, and subsea pipelines in the oil and gas world.
This matters for Brazilian professionals in at least two respects. First, Brazil's energy planning agencies and the nascent offshore wind licensing framework will eventually need to decide which technical standards apply to local projects. DNV's recommended practices are among the most widely referenced globally, and Brazilian regulators — including ANEEL and any future offshore wind oversight body — are likely to look to this ecosystem of standards when drafting technical requirements. Understanding the direction DNV is moving helps anticipate where Brazilian technical requirements may land.
Second, the engineering and project management workforce that Brazil is beginning to develop for offshore wind will need familiarity with these standards. Many of the professionals who will staff Brazil's offshore wind projects in the coming years are currently working in oil and gas — on FPSOs, subsea systems, or marine operations. The transition pathway for that workforce runs directly through documents like DNV-RP-0585. Firms investing in workforce development for the energy transition would do well to track the evolving standards landscape, even where immediate applicability is low.
There is also a supply chain dimension. Brazilian fabricators, engineering consultancies, and offshore service companies exploring diversification into wind are competing — or will compete — for work on international projects where seismic design compliance may be a contract requirement. A Brazilian EPC firm bidding on a wind project in a seismically active jurisdiction will need to demonstrate fluency with the updated DNV guidance. That is a capability-building consideration, not a distant abstraction.
Finally, the update is a reminder that the offshore wind sector is not waiting for oil and gas incumbents to engage on their timeline. The standards ecosystem is advancing, certification pathways are being defined, and the technical expectations for project developers and their contractors are rising. Brazilian companies evaluating when and how to enter the offshore wind market will find that the entry bar is being set — with or without their input.
CONTEXT
DNV has been systematically expanding its recommended practice library for offshore wind over the past several years, covering areas from floating foundation design to cable systems and environmental loading. The seismic update to DNV-RP-0585 fits within that broader pattern of standards maturation. Comparable work is underway at other bodies, including the IEC and ISO, reflecting a sector-wide effort to give offshore wind the same engineering rigour that underpins oil and gas certification.
For Brazil specifically, the offshore wind regulatory and licensing framework remains a work in progress. The pace at which international standards like DNV-RP-0585 become relevant locally will depend significantly on how quickly that framework advances and which technical references Brazilian authorities choose to adopt or adapt.
