Multiconsult is reassessing hydropower plants with underwater ROVs to prevent dam failure

According to NVE, 625 dams in Norway are vulnerable to increased flooding due to climate change. Over 1,000 bridges have damage of a significant nature that threatens their load-bearing capacity (NRK). A few weeks ago, we also witnessed a bridge collapse in Tretten; fortunately, no lives were taken.
Bridges, dams, hydropower plants, quays, and other similar infrastructure are affected by the sea and weather. They need supervision and follow-up to ensure that the necessary maintenance is carried out. Wearing and damage are quite easily detected on the upper side of these structures, but it's important not to forget the parts located underwater.
Several of Multiconsults engineers carry out annual reassessments of hydropower plants. Ensuring that Norway's hydropower plants are in a safe condition to supply electricity has not become less important with increased prices and the war in Ukraine. It is important to have reassessments carried out to prevent dam failures. We chatted with Anders Tørklep from Multiconsult to learn more about how they use ROVs as part of their service offering to the hydropower plants in Norway.
Both biologists and engineers at Multiconsult use underwater ROVs from Blueye
Multiconsult is a Norwegian engineering and architecture company. With over 3,000 employees in various fields, they offer services in planning, design, environmental studies, project management, and the like.
Since 2019, Multiconsult has enriched its service offering with the Blueye ROV to be able to take pictures and videos during assessments and inspections of underwater objects. Today, ROVs are used by biologists as well for various observations, and engineers put the ROVs to work at dams and hydropower plants. The ROVs enable inspections without draining dam facilities, which is both expensive and time-consuming.
