The audit was conducted from 11 to 15 March 2024.
Objective
The objective of the audit was to verify how Gassco handles SIL in operations, with a focus on safety systems, and the company’s follow-up of performance requirements, so that the safety level is maintained and improvement measures are implemented where necessary.
Result
The audit identified non-conformities concerning the following:
- Classification of safety-critical equipment – gas detectors
- Knowledge of weaknesses in safety-critical equipment – emergency shut-off valves for the pipelines
We also observed three factors that we have chosen to categorise as improvement points. These concerned:
- Collection, processing and use of data
- Relationship between assumptions made and results achieved
- Securing the performance of safety functions
What happens now?
We have asked Gassco to report to us by 24 May 2024 on how the non-conformities will be addressed, and to give us their assessment of the improvement points observed.
