Breakfast seminar: Offshore Norge’s revised Guideline 104 – Cybersecurity baseline requirements for Operational Technology (OT) systems

Offshore Norge is currently developing a new revision of its guideline for cybersecurity 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 end of May 2026. To introduce the upcoming revision to the industry, DNV is hosting this breakfast seminar on behalf of Offshore Norge.

Join us for a clear, practical look at how ON 104 will shape OT cybersecurity on the Norwegian Continental Shelf. Together with Havtil and Aker BP, we will walk through what the update means for operators, regulators, and suppliers across the petroleum sector.

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.
