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