Olav Erik Hagen AS is a diving company established in 1991 with headquarters located in Stryn, and now also located with branches in Bergen and Kristiansand. We have during these years built extensive experience with complex diving operations in challenging environments from coast to inland and mountains. With mobile equipment and personnel, we have easy access to the whole country.

Our diving operations are done according to laws and regulations stated by The Norwegian Labour Inspection Authority. We also do operations according to Norsok U-103, and are pre-qualified to DNV-GL Veritas, Sellicha, StartBank and Nexans. Our divers are experienced professionals certified for underwater blasting, and inspection of steel and concrete constructions.

We have for many years utilized ROVs (Remotely Operated Vehicles) for inspection and construction support and made investments in 2017 in ROV-systems and sensors for inspection of flooded tunnels and pipelines, and operations inshore and offshore. Inspection of tunnels are done in cooperation with Norconsult AS with delivery of complete 3D models.
