The audit was conducted as a meeting where Shell presented its work on risk analyses, and the PSA had the opportunity to request verifications and question relevant personnel.
Background for the audit
The HSE regulations are function-based and assume that the players aim at the lowest possible risk.
The development, implementation, use and follow-up of quantative risk analyses in a systematic and traceable manner is an important contribution towards managing risks throughout all stages of a facility's lifetime.
The requirement basis for this activity is mainly stipulated in Section 15 of the Management Regulations relating to quantitative risk analyses, as well as other relevant requirements in Chapters I, II, IV and VI of the Management Regulations, in addition to requirements in Section 9 of the Framework Regulations regarding principles for risk reduction.
Purpose of the audit
The purpose of the audit was to assess whether Shell has established internal requirements and work processes to ensure that the assumptions, restrictions and recommendations in the risk analyses are safeguarded.
In our notification letter we asked Shell to present its requirements and guidelines along with practical examples, as well as experiences from Draugen and Nyhamna.
Furthermore, we asked Shell to give an account of any areas of improvement which they had identified.
Result of the audit
Our general impression is that Shell conducts many important activities related to the implementation and use of quantitative analyses of risk on Draugen and Nyhamna.
We have also established that there are important improvement areas, to a large extent identified by Shell itself, and particularly related to deficient systematising and formalising of requirements and guidelines.
