The audit was conducted from 31 May to 18 June 2021. 


The objective of the audit was to assess how Equinor ensures compliance with the authorities’ regulations relating to barrier management at Sleipner A, R and T, and how the Sleipner organisation is working to reduce the risk of hydrocarbon leakage. We also sought to assess whether the personnel were enabled to handle hydrocarbon leakage at Sleipner through their instruction, training and drills.


Seven non-conformities were identified in the following areas:

  • Barrier management
  • Process safety
  • Maintenance of fire doors
  • Training and verification of performance requirements for operational and organisational barrier elements
  • Mapping and analyses of the working environment, including workload analyses
  • Working hours management
  • Non-conformity handling


In addition, four improvement points were identified relating to:

  • Risk reduction
  • Follow-up of risk management system
  • Assessment of the assumptions in the total risk analysis (TRA)
  • Basis for changing the fire door maintenance programme at Equinor

What happens now?

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

The reply deadline is set at 28 January 2022.
