About us

Dr.techn. Olav Olsen AS provides services in the fields of structural engineering, marine engineering, geotechnical and environmental engineering and hydrology.  The volume of assignments is mainly related to all types of buildings, transport, industry and ports, dams, marine and offshore structures, including aquaculture and renewable energy. We work with all phases of a project, such as concept studies, detailed design, verification, follow-up in the construction phase, condition assessments, lifetime extensions, reconstruction and rehabilitation.

The company was founded in 1962 by Olav Olsen. He was a very skilled student and famous for his theory: "Continuous Shells" ® In short, one can say that the company is built on his doctoral thesis on concrete shell structures. 

60 years of resilient and socially beneficial structures have given us a substantial competence bank. From the early 1970s, the company played a significant role in the development and engineering of the Condeep platforms in the North Sea, which has made major contributions to the development of modern Norway.  We are now applying this core competence to a wide range of tasks such as fjord crossings, urban development, fixed and floating foundations for offshore wind and other structures in and by the sea.

Our three values - COMPETENCE - VALUE CREATION - COMMITMENT is strongly rooted in our company’s profile and important in all our projects. We take the environment seriously and are eco-lighthouse certified. 

Dr.techn. Olav Olsen AS today, has 120 employees at Lysaker outside Oslo and in Trondheim.  In 2020, we became part of Artelia Group, an engineering company with a presence in 40 countries, more than 6,000 employees and headquarter in France.  Artelia also owns the Danish advisory company MOE.  As a natural development of the collaboration, MOE's advisors in Norway will be included in day-to-day operations and thereby expand Olav Olsen's services with technical engineering.  Read more about our projects under business areas.
