The audit was conducted between 5 and 9 December 2022.


The objective of the audit was to ensure that Equinor has established systems for condition monitoring, maintenance and repairs of concrete structures and tension legs on the Heidrun TLP so as to ensure its safety.


One non-conformity was identified relating to the follow-up of manning and competence.

Three areas with potential for improvement were also identified. These concerned:

  • Overall plan for performance of the maintenance programme
  • Use of data for marine fouling on tension legs
  • Reporting of damage in CODAM

What happens next?

We have asked Equinor to report to us by 17 February 2023 on how the non-conformity will be addressed, and for their assessment of the improvement points observed.
