The audit was conducted from 28 March to 14 April 2023. 


The objective of the audit was to monitor that the work of the business unit (RE – Norne, Snøhvit, Aasta Hansteen) to evaluate and improve the maintenance of Aasta Hansteen, including following up the effects of changes to maintenance, is contributing to the improvement of HSE. 

We also sought to verify how the work to improve maintenance management was ensuring that the causes of HSE risk/uncertainty are identified and followed up. 


We identified eight non-conformities in this audit. These concerned: 

  • Classification 
  • Planning and prioritisation 
  • Maintenance programme 
  • Follow-up 
  • The manning of planned maintenance 
  • Breach of the working hours provisions 
  • Organisation of the work, risk assessment and measures 
  • Arrangements for employee participation 

We also identified one improvement point concerning regulatory competence in respect of working hours provisions and requirements for adaptations. 

What happens next? 

We have asked Equinor to report by 25 August 2023 on how the non-conformities will be addressed, and for their assessment of the improvement point observed.
