Trends in risk level in the petroleum activity (RNNP)

The trends in risk level in the petroleum activity (RNNP) process aims to measure and improve health, safety and environmental conditions in this industry.

It was initiated in 1999-2000 to develop and apply a measuring tool which illustrates the development in risk level on the Norwegian continental shelf (NCS). The process plays an important role in the industry by contributing to a shared understanding of risk development by companies, unions and government agencies.

RNNP has become an important management tool for all participants in the petroleum sector. Its findings are valuable for our planning of supervision activities and development of the regulations.

The results of the process are presented in annual reports.

The main report is published every April. Totalling more than 400 pages, this comprehensive document comprises two sections in Norwegian covering the NCS and the land-based plants respectively. A summary report of almost 50 pages is published for the NCS in both Norwegian and English.

RNNP risk data related to acute oil and chemical spills are provided in a separate report in Norwegian every autumn.

Qualitative and quantitative methods
The RNNP process is based on two methods which complement each other.

  • Describing defined hazard and accident conditions (DFUs) – indicators which are critical for safety and the working environment – has permitted a set of measuring tools to be developed. These provide information about trends in risk level on the NCS.
  • Questionnaire surveys, interviews, fieldwork and other studies also form the basis for social science analyses.

Personal risk and environmental factors
The project focuses on personal risk and includes

  • major accidents
  • work accidents
  • selected working environment factors
  • acute discharges.

The studies are confined to our area of authority, with the exception of helicopter transport of personnel. The latter is covered in cooperation with the Norwegian Civil Aviation Authority and helicopter operators on the NCS.

Work covers:

  • all permanent and mobile facilities on the NCS
  • transport of personnel by helicopter between departure from/arrival at the heliports to landing on/departure from the facilities
  • the use of vessels within the safety zone around the facilities
  • eight land-based plants.

Continuous Improvement
In order to describe developments in risk level as well as possible,  continuous efforts have been made to identify new methods, risk areas and other key parameters. These can provide further understanding of which risk factors are the most important to track over time.

  • 2001: the first questionnaire survey is implemented. The objective is to get employees on the NCS to describe how they perceive HSE conditions at their workplace. This survey has been carried out every second year.
  • 2004: field work is carried out for the first time at selected facilities which have shown positive development. Fieldwork aims to identify which factors or measures might have contributed to this
  • 2006: eight land-based facilities are incorporated in the process.
  • 2010: The risk of acute discharges is integrated in the RNNP process. A separate report is published every autumn.
