scope:

This NORSOK standard describes risk and emergency preparedness assessments for offshore and onshore facilities for production of oil and gas. Where applicable, this NORSOK standard may also be used for mobile offshore drilling units.

This NORSOK standard covers the process of planning and execution of risk and emergency preparedness assessments, including how to establish the risk picture and the assessment of potential risk reducing measures. Risk treatment, i.e. the process and decisions related to how to deal with identified risks (e.g. acceptance, the need for modifications and/or implementation of risk reducing measures) are, however, not covered by this standard. Nor is the establishment of risk acceptance criteria covered by this NORSOK standard.

This NORSOK standard covers risk for major accidents. Analysis of occupational fatalities and injuries are not covered in this NORSOK standard although this risk contribution from occupational fatalities often is included in risk calculations. Nor does the standard cover occupational health risk aspects, including physical and psychological working environment, working environment mapping and analysis.

This NORSOK standard covers requirements related to the risk assessment processes which include a quantitative risk analysis.

NOTE Requirements related to qualitative risk analysis are only briefly addressed.

This NORSOK standard does not cover security aspects, except from some implications for the emergency preparedness analyses.
