Norwegian Tunnel Inspection AS was founded back in 2016 with the purpose of exploring the untapped marked of long excursion tunnel inspections connected to hydroelectric powerplants.

During many years of working in offshore, inshore ROV, diving and subsea-industry, there has been requests from owners, entrepeneurs and consulting companies who have been concerned about the integrity and condition of various flooded tunnels.

During the evaluation of these requests, we came to the same conclusion every time; the scope of work represent to high of a risk for divers and the ROV-systems used in offshore operations requires to much infrastructure, are to heavy, has to high operating costs and simply can not take on many of the requested tunnel lengths due to operational limitations.
