ROV - underwater inspection with "Remotely Operated Vehicle"
Inspection with ROV is a special service in Norconsult for inspection of submerged objects. This offers great advantages when draining is expensive or not feasible. In other cases, consideration of HSE can be crucial. Norconsult has used micro-ROV (Videoray) since 2001 and has completed more than 200 assignments in Norway and internationally. Especially in connection with condition control in hydropower, but also in other contexts.
The equipment has a range of up to 600 meters with a depth of 300 meters. The ROV is equipped with light, video, laser, sonar, thickness gauge, and a positioning system. This enables good documentation and measurement of objects, even where visibility is very poor. The equipment is compact and can be transported by car or helicopter.
Norconsult is also a partner with the diving company O.E. Hagen for inspection of longer water-filled tunnels. O.E. Hagen operates a larger ROV, while Norconsult is responsible for data collection, post-processing, assessment and presentation of collected data. The ROV has a maximum range of 6 km from the entry point, i.e. up to 12 km, and is equipped with multi-beam sonar for 3D scanning. The result can be used independently or for integration in BIM engineering. The equipment is divided into several modules for possible helicopter transport.
