HSE research under the direction of the PSA

As part of the HSE research in the Oil and Gas Project, the PSA has secured earmarked funds to implement its own research and development projects.


List of PSA's main research projects:

  1. Trends in risk levels on the Norwegian continental shelf, Torleif Husebø
  2. HSE culture, Elisabeth Lootz
  3. Development of new principles in the control room, Trond Sigurd Eskedal
  4. Heat exposure of process equipment, Harald Olstad

Description of the research projects

Trends in risk levels on the Norwegian continental shelf

The purpose of the project is to:

  • measure the impact of safety-related measures in the petroleum industry.
  • help to identify areas which are critical for safety and in which priority must be given to identifying causes in order to prevent unplanned events and situations.
  • improve understanding of the possible causes of accidents and unplanned situations together with their relative significance in the context of risk, in order to create a reliable decision-making platform for the industry and authorities which will enable them to direct their efforts towards improving conditions of health, safety and the environment.

The work will also help to identify potential areas for making regulatory changes and for conducting research and development.

The project is based on two complementary evaluation processes:

  • The registration, analysis and evaluation of data relation to defined situations of hazard and accident and the efficiency of barriers
  • The performance of sociological analyses using free text analysis of questionnaires, workshops and interviews

The project focuses on risk to personnel and covers major accidents, occupational accidents, work environ¬ment factors and a number of minor accidental events

Health, Environment and Safety culture

  • The project is headed by Petroleum Safety Authority Norway and has been run over a period of 3 years (2002-2004). The goals of the project have been:
  • Clarify how to understand the concept of HSE-culture
  • Develop a dialogue with the industry and research environments - nationally and internationally
  • Integrate this thinking in the PSAs supervision activities
  • Internal and external competance development through seminars and national conferences
  • Compose a written HSE-culture guideline (link)

Heat exposure of process equipment

About the project:
Comparison between different standards on recommmended heat loads from flames shows great variation. In general, heat loads from flames do vary in space and is dependent on fuel and surrounding conditions. Heat exposure in standards should be a carracteristic heat load representing the average exposure of an object. It is difficult to identify a carracteristic heat load by measuring heat flux in local points in a flame.

The project startet in 2002, and the objective was to answer the question:'What is a relevant heat load, and how should it be modeled'. Key issues in the 2003 project was heat transfer between materials, liquids and gas.
