The audit was conducted from 7 to 10 November 2022.


The objective of the audit was to monitor how Equinor is working to reduce the risk of major accidents, with a focus on preventing losses of containment. We also wanted to monitor how the company handles integrity and barrier management of corrosion under insulation (CUI) and flexible risers, as well as the interaction of float and riser movements at Troll B, and ensure that operations comply with internal requirements and the regulations.


No non-conformities were identified during the audit.

Two improvement points were observed. These concerned:

  • Follow-up of maintenance of emergency shutdown valves for risers
  • Follow-up of policy documents

What happens now?

We have asked Equinor for their assessment of the improvement points observed. The deadline for reply is set at 15 January 2023.
