Materials testing

DNV GL has specialized materials laboratories located in Norway (Oslo and Bergen), UK (Loughborough), Singapore and the US (Columbus, OH). 

Some of our specialities are:

  • Advanced fatigue and fracture mechanics testing
  • Testing in realistic corrosion environments
  • Qualification of composites, rubber materials and fibre ropes
  • Qualification testing of coatings
  • Mechanical testing.

Value added through tests we do

The quality of materials is crucial to the quality of products and the safety of systems. 

Whether you run a production facility, operate complex technical equipment or supply raw materials efficient and reliable materials testing and qualification improves safety and technical performance, and reduces risks and costs. Defining the appropriate method of materials testing requires expertise in both materials and systems.

The aim of corrosion testing is to understand resistance to degradation by corrosion mechanisms or hydrogen-induced stress cracking (HISC), and to select appropriate actions to reduce the risk of failure. We carry out qualification testing to meet requirements, to sour service, coatings, anode testing and others, and run specific materials test setups to simulate operational environments, including corrosion in seawater, microbiological influenced corrosion (MIC), and stress corrosion cracking

Our materials testing laboratories contribute to quality assurance during production by carrying out a broad range of destructive and non-destructive testing (NDT) using the latest technical equipment. 

Areas where we combine testing and system knowledge

Our customers cover the entire oil and gas value chain, and we also serve other industries such as maritime, renewables and automotive. 

A materials testing and qualification will typically verify material properties according to a specification, code or standard or as part of a customized fitness for service assessment.
