Breakfast seminar: Introducing the revision of Offshore Norge’s guideline for cybersecurity in operational technology (OT) systems, NOG 104

Offshore Norge is currently developing a new revision of its guideline for cyber security in OT systems, formerly known as NOG 104 and now renamed Offshore Norge 104 (ON 104).

ON 104 Revision 7 is planned for release towards the beginning of June 2026. To introduce the upcoming revision to the industry, DNV is hosting this breakfast seminar in Bergen.  

In addition, DNV will introduce a new recommended practice on cyber security barrier management (DNV‑RP‑G110), providing practical guidance on how to apply barrier management principles to OT cyber security. 

Join us for a clear, practical introduction to how ON 104 will shape OT cyber security on the Norwegian Continental Shelf – and how barrier management can be used to operationalise and strengthen cyber security in practice. 

Who should join: 

Whether you work in cyber, operations, risk, or governance, this seminar will help you understand what ON 104 means for your organisation—and how to move forward with clarity and confidence.
