As your partner, we ensure that structural damage or changes won't cause you costly surprises.

 What we will deliver to you:

1. Underwater surveys: We perform underwater inspections for bridges, ports, pipelines, oil terminals, offshore wind farms and hydropower plants using multibeam sonar below the surface and laser scanner for structures above the surface.
2. Post-processed 3D data: You get an easy access to the 3D point cloud inspection data processed by us. Our licensed marine inspectors make interpretations and observations of the data to help you create detailed maintenance plans.
3. Gisgro online-report & written inspection report: You receive the high quality 3D data through our Gisgro online-service and a written inspection report with expert interpretations. Gisgro enables easy management, communication and utilisation of collected survey data. All data can be stored, compared and analyzed in one place, without any additional softwares, only with a web browser.
4. We help you to utilise the inspection results smartly in predictive maintenance and asset integrity management in all phases of the structures’ life-cycle.

What our customers say about us

We have helped hundreds of customers since 2010 in the Nordic countries, Germany, the Netherlands and UK to receive a combined digitized view of underwater assets with multibeam sonar inspections. Here are some examples of  our services.

“We would recommend every port to do this kind of surveys, and VRT has delivered to the fullest of our expectations. When we do another survey in 2019 or 2020 we will then have a history and can compare the reports one to the other. By using the same company, we will get a perfect overview and can easily see any changes in the conditions.” Svein Tore Nordhagen, Harbourmaster, Port of Mo i Rana

“We regularly examine the area of foundations at river bridges to determine if there are any sinkholes or other damage below the water surface. Our cooperation with VRT aims for long-term monitoring as the 3D data is saved to compare the possible structural changes with future surveys.” Gregor Walter, Construction Manager & Head of Bridge Construction Department, City of Regensburg

“Compared to more traditional inspection methods, such as diving, VRT’s multibeam sonar underwater inspections allow investigating longer dam structures and perceiving the condition more accurately. VRT’s clear 3D point cloud data helps us to efficiently improve dam safety in the long-term.” Tomi Mäki, Specialist, Water Resources Engineering, ELY Centre for Southern Ostrobothnia
