Risk level - the Norwegian continental shelf (NCS)

This project is intended to provide an overview of the level of risk on the NCS, the present status and trends.

The risk level NCS project (RNNS) was initiated by the Norwegian Petroleum Directorate in 2000, and has been continued by the Petroleum Safety Authority Norway since 2004.

It measures the effect of health, safety and environmental work by the industry as the basis for identifying areas critical to HSE.
The project provides a basis for decision-making by the industry and the authorities on preventive safety and contingency planning.
Focused on the risk to people, it covers major incidents, accidents at work and working environment factors. Both qualitative and quantitative risk indicators are applied.

The UiS has played a key role in developing the methods used in the RNNS project. Its researchers are now working to develop methods for land-based plants and to transfer the approach from offshore activities to other sectors.

Reference is made to the PhD study being pursued by Bjørnar H Knudsen.

Methodology for risk assessment
Bjørnar H Knudsen is working on a PhD which aims to develop a suitable methodology for risk assessment at national level.

This study starts from the principles, methods and models developed by the RNNS project to assess the status of and trends in the safety level on the NCS.

A similar approach can be taken in other industries and sectors, and provides the basis for a national system of risk assessment.
The project will help to give such thinking a scientific platform and to shape important building blocks for an assessment system at national level.
