BORA – barrier analysis

The barrier and operational risk analysis (BORA) project aims to develop a method for conducting such assessments in the operational phase.

This method involves modelling barriers, and takes account of operational conditions as well as human and organisational factors.

The quantitative analysis embraces not only barriers designed to prevent the occurrence of undesirable incidents, but also those meant to limit the consequences of any incident which does occur.

It provides a framework for identifying critical factors, failures and combinations of failures causing risk, and for studying the effect of risk reducing measures.

Work in the project has focused on the risk of fire and explosion in the process area.

The analysis will help to give the barrier overview and insights required of the industry by regulations (Safety management regulations), and which have been judged insufficient by the risk level (RNNS) project.

This project has been and continues to be pursued in close cooperation with the industry.

Funding and partners
Funding is provided by the Research Council of Norway, the Petroleum Safety Authority Norway, the UK Health and Safety Executive (HSE), the Norwegian Oil Industry Association (OLF) and Statoil.

The work is being carried out jointly by the UiS, the Norwegian University of Science and Technology (NTNU), Safetec and the Norwegian Institute for Energy Technology (IFE).
