The Petroleum Safety Authority Norway (PSA) has carried out an audit of Equinor’s follow-up of the maintenance of concrete structures and tension legs on the Heidrun TLP, between 5 and 9 December 2022.
Objective
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 to ensure its safety.
Result
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:
- The overall plan for performance of the maintenance program
- Use of data for marine fouling on tension legs
- Reporting of damage in CODAM
PSA Norway asked Equinor to report by 17 February 2023 on how the non-conformity will be addressed, and for their assessment of the improvement points observed.
