New report on the status of technology for non-metallic materials, including joining

The Petroleum Safety Authority Norway has conducted a study with Sintef, the purpose of which has included summing up the status of the technology and clarifying the concept of robustness in relation to the use of non-metallic materials and their properties.


The petroleum industry wants to employ new technical solutions to satisfy the needs created by
aggressive chemicals and longer lifetime, as well as requirements for low weight and high performance.

Knowledge about the use of non-metallic materials and their properties is key to choosing the right solutions.

On the basis of this, the Petroleum Safety Authority Norway has conducted a study with Sintef in 2006, with the purpose of

  • summing up the status of the technology for non-metallic materials and the joining of these, both in offshore applications and in petroleum facilities on land,
  • contributing to clarification of the concept of robustness in relation to the use of non-metallic materials and their joining, including evaluation of ageing effects in materials.

The report from this study, ?State of the art: non-metallic materials, including joining? - gives a summary of the status of the technology for the use of polymers and plastics-based composite materials in the oil and gas industry.

The report discusses selected applications with respect to status, aspects which are critical for safety, testing methods and factors which influence reliability and robustness.

Three factors which limit the use of composites in major load-bearing structural constructions are highlighted:

  • the lack of available materials data and standards and guidelines for design og dimensioning
  • limited knowledge of, and familiarity with these materials in user communities and among engineers who are used to working with traditional materials
  • generally higher costs in connection with materials and production techniques.

The report is only available in Norwegian.

The report ?State of the art: non-metallic ? ? is based on the project/report "Robust material selection", also conducted by Sintef in the period 2002-2004 as a contribution to undersanding the concept of robustness which is used in Section 9 of the Facilities Regulations.
