Project objectives

The main goal of the project is to establish criteria and solutions for safe and cost-effective application of materials for hydrocarbon exploration and production in arctic regions.

Sub goals:

  • Extend the application range for structural steels by characterisation of brittle fracture resistance in welded steel structures including the effects of geometry constraint and local variation of material properties
  • Define criteria for low temperature application for steel and weldments including safety factors (design temperatures down to -60°C)
  • Develop specifications for qualification testing of materials to be applied down to -60°C
  • Define materials criteria for safe application under large deformation (strains > 5%) of pipelines and other structures including safety factors
  • Develop requirements for polymer coatings to be used down to -60°C, and under large temperature variations
  • Develop basis for application of light weight structures using materials like high strength steel, composites, and hybrid solutions
