Key findings from a DNV‑led research initiative have been written into the international standard that guides station keeping for floating offshore structures, the changes confirmed in a report published on 15 October 2026 by reports.
The research, carried out under the NorMoor joint industry project and led by DNV with backing from a range of offshore industry partners, has been incorporated into the third edition of ISO 19901-7. The change brings the JIP's technical work into the formal standard used for mooring and station keeping systems.
The update to ISO 19901-7 concerns station keeping systems for floating offshore structures and mobile offshore units. The revision incorporates NorMoor results to deliver a more consistent reliability-based framework for assessing and designing mooring arrangements.
What the revision introduces
According to the report, the third edition adopts the NorMoor JIP's key outcomes so that operators and designers share a common approach to reliability. The change is intended to align practices across projects by providing clearer guidance on how reliability should be evaluated for station keeping systems.
Industry collaboration and scope
NorMoor was executed as a joint industry project under DNV leadership and supported by offshore industry partners. The incorporation of its findings into an international standard reflects the collaborative route the industry has used to reconcile differing practices in mooring assessment.
The revised standard applies to floating production units and mobile offshore units where station keeping is a critical safety and operational consideration. The report stresses that the update is focused on establishing consistent, reliability-based principles rather than prescribing a single technical solution.
The move to embed research outcomes into ISO 19901-7 is likely to influence how owners, designers and contractors frame technical requirements and acceptance criteria for mooring systems. By providing a shared reliability framework, the standard aims to reduce variation in design assumptions and assessments between projects.
Adoption of the third edition will depend on how quickly industry stakeholders and regulators align project specifications and approval processes with the revised text. The report published on 15 October 2026 by reports records the change but does not set an implementation timetable, leaving the pace of uptake to be determined by individual jurisdictions and contracting parties.
The practical effect of the revision will become apparent as operators and their advisers apply the revised standard in procurement, engineering and certification work. The incorporation of NorMoor findings into ISO 19901-7 marks a step towards greater technical harmonisation in the offshore sector and signals the value placed on collaborative research to resolve common engineering challenges.
The reports item provides the account of the standard revision and the background of the NorMoor joint industry project led by DNV. The industry will now watch how the new edition shapes project practice and whether it prompts further research or future updates to related guidance.
