PDS Research Projects
Since 1986, SINTEF Technology and Society, Dept. of Safety Research (previous Safety and Reliability) has had a major activity on theory, techniques and tools for the design, validation, operation and evaluation of computer-based control and safety systems in the process industry. Some of the main deliverables from the research projects are the PDS-method and associated data handbook which have gained a widespread use in the Norwegian petroleum industry. The research has been sponsored by the Research Council of Norway and PDS members.

PDS project 2012-2016

"Tools and guidelines for overall barrier management and reduction of major accident risk in the petroleum industry"

The project included the following main activities:

  • Development of an overall method for barrier management
  • Development of improved methods and data for modelling of dependencies between barriers and barrier elements
  • Evaluation of how new technology – and wireless technology in particular – may affect the performance of the barriers
  • Development of industry guidance for overall barrier management including technical, operational and organisational barrier elements for all relevant lifecycle phases


PDS project 2010-2012

"Development of barriers and indicators to prevent and limit pollutants to sea"

This PDS project focused on barriers and indicators for preventing and limiting accidental releases of hycrocarbons to sea. The project was sponsored by Research Council of Norway and the PDS participants.


PDS project 2007-2009

"Managing and follow-ut the integrity of safety instrumented systems"

This PDS project focused on how to practically implement IEC 61508/61511 and how to follow-up the integrity of SIS in the operational phase. The project was sponsored by the Research Council of Norway and the PDS members and included the following main activities:

Updating the PDS data and method handbook (new versions were issued in January 2010)

Using the method for practical SIL implementation and SIL follow-up in the operational phase

Developing an example collection on how to use the method on practical projects


PDS project 2006

"Secure Safety (SeSa)"

In this project a systematic and methodological approach to assess whether a given technological solution for remote access to SIS is acceptable was described in a separate SeSa project report.


PDS project 2003-2005

"User friendly analysis tool for safety instrumented systems"

The project was sponsored by the Research Council of Norway and the PDS participants, and included an update of the model for common cause failures, revised modelling of systematic failures as well as an update of some definitions and terminology to be in line with the IEC 61508 taxonomy.


PDS project 1992-1993

"Control and Safety Systems Reliability (PDS II)"

The project analysed the reliability, maintainability and maintenance support of process control and safety systems in offshore oil and gas production. It provided guidelines for improving the design and operation of the control and safety systems, and methods were developed for assessing the overall control and safety system reliability, considering human as well as technical safety barriers. Various methods for task analysis and human reliability analysis of control and safety systems were also described, and specific requirements on how to reduce human errors during maintenance of control and safety systems were obtained.


PDS project 1987-1990

"Reliability and Availability of Computer Based Process Safety Systems (PDS)"

In this project analytical models and methods were developed for assessing the overall reliability and Life Cycle Cost (LCC) of computer based process safety systems. Safety system configurations that maintain high production regularity (low LCC) and at the same time fulfill the safety requirements were identified. This initial PDS project mainly considered Emergency Shutdown (ESD) systems.
