The audit was conducted between 29 January and 13 February 2020.


The background to the audit concerns previous follow-up activities involving Equinor relating to flexible risers, previous incidents and the potential risk entailed by the weakened integrity of flexible risers.


The objective of the audit was to follow-up Equinor’s integrity, risk and barrier management of flexible risers and the safety system at Snorre B and verify that operations are compliant with internal and regulatory requirements, including continuous improvement and risk reduction.


Six non-conformities were identified, relating to:

  • Assessment of the consequences of the worst credible process fire
  • Planning and prioritisation of observations in the TIMP tool
  • Operation of flexible risers
  • Systematic follow-up of emergency shutdown valves
  • Competence management
  • Maintenance management of flexible flowlines

Three improvement points were identified, relating to:

  • Regular assessment of the assumptions in the total risk analysis (TRA)
  • Follow-up of MiS Risk
  • Alarms in central control room

What happens next?

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

The deadline for replying is set at 15 April 2020.
