Information about myself
After receiving a Dr.ing. degree from NTH in 1984, I joined Statoil Research Centre in
In 1991 I joined CorrOcean in a combined management/technical position to develop the company from a small national company to be a leading international company within “Corrosion monitoring and corrosion management”. During my 13 years with CorrOcean the company grew from 30 people to 350 people with activities in all the major oil regions in the world. I also got the opportunity to visit the most important regions with oil activities in the world including Asia,
After 20 years in oil industry I accepted an offer to be a Professor within “Corrosion and Surface Technology” at IPM in 2004. I still have good contact with the industry and use my contact and experience to develop my courses and to get interesting industrial related projects both for master students and for PhD candidates.
I am present manager for the Strategic Area Materials (Tematisk Satsingsområde Materialer) at NTNU.
Fields of interest
- Material technology for the oil industry
- Corrosion of metallic materials for the process industry
- Corrosion protection by cathodic protection and/or coating
- Corrosion, erosion and wear resistant materials and surfaces
- Tribology (including tribo-corrosion)
- Integrity management of production systems
- Hydrogen embrittlement of metals
