The audit was conducted from 15 to 23 August 2023.


The objective of the audit was to carry out an audit of Equinor's application of experience from the start-up and operation of Johan Sverdrup phase 2 for learning purposes, so as to reduce the probability of failure, hazard and accident situations linked to HC leaks.


Three non-conformities were identified, concerning:

  • Deficient follow-up of the alarm systems
  • Deficient notification or reporting of incidents
  • Shortages of temporary containers

In addition, five improvement points were identified, concerning:

  • Barrier management
  • Collection of maintenance history
  • Start-up and operation of facilities
  • Follow-up
  • Planning the insulation work

What happens next?

We have asked Equinor to report by 23 October 2023 on how the non-conformities will be addressed and for their assessment of the improvement points observed.
