PDS Research Projects
Since 1986, SINTEF has had a major activity on developing theory, techniques and tools for the design, validation, operation and follow-up of industrial control and safety systems in the petroleum 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 Norwegian Research Council and PDS forum members.

Automatized follow-up of safety instrumented systems (2019-2022)

The project will develop specifications that simplify and automate design and operation of safety systems in the petroleum industry. The industry partners will, based on the R&D activities in the project, develop new solutions for collecting, analyzing and sharing failure data of safety systems during design and operation.

Tools and guidelines for overall barrier management and reduction of major accident risk in the petroleum industry (2012-2016)

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

Development of barriers and indicators to prevent and limit pollutants to sea (2010-2012)

This project focused on barriers and indicators for preventing and limiting accidental releases of hydrocarbons to sea.

Managing and follow-up the integrity of safety instrumented systems (2007-2009)

This project focused on how to practically implement IEC 61508/61511 and follow-up the integrity of SIS in the operational phase.

Secure Safety (SeSa) (2006)

The project presented a systematic and methodological approach to assess whether a given technological solution for remote access to SIS is acceptable.

User friendly analysis tool for safety instrumented systems (2003-2005)

The project provided an improved model of systematic failures and common cause failures, as well as an update of definitions and terminology in the PDS method to be in line with the IEC 61508 taxonomy.

Control and Safety Systems Reliability (1992-94)

The project analyzed 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.

Reliability and Availability of Computer Based Process Safety Systems (PDS) (1987-1990)

The project developed analytical models and methods 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.
