The audit was conducted on 29 and 30 January 2024.


The objective was to audit the operation, maintenance and barriers associated with the internal condition of the pipelines in the trunkline system from Norne via Åsgard Transport to Heidrun and via Haltenpipe to Tjeldbergodden and how the companies work to prevent loss of containment.

We also wanted to verify the requirements defined for barriers, condition monitoring and maintenance in respect of this function.


No non-conformities were identified during this audit.

Two improvement points were identified. These concerned:

  • Learning and continuous improvement
  • Follow-up and verifications

What happens now?

We have asked Gassco and Equinor to provide us with an assessment of the improvement points observed by 15 April 2024.
