VRT’s 3D surveys produce georeferenced data of the surveyed assets or areas. Every single point of the point cloud has its XYZ coordinates in a defined coordinate system. The combination of RTK (Real Time Kinematics) and PPK (Post-Processing Kinematics) ensures that the data is accurate enough to be used in various asset management operations. Continue reading…

3D surveys of underwater assets have been the core business for VRT already for a decade. We have inspected hundreds of ports, bridges, hydropower plants and pipelines during those years. In the beginning we had a challenge to deliver the gathered 3D data to our clients, as very few of them had the software or skills to use the data. We printed out booklets of visualization pictures and sent them to our clients by post with the inspection report also on paper. Not a very high-tech approach! Continue reading…

When you need to have data from underwater structures, most often the situation is that you need someone to a) gather, b) process, c) analyse and d) utilise the data. You can search for a different service provider for each phase or order the whole survey process as a service. Continue reading…

The discussion about condition of freshwater and wastewater pipelines has been in Finnish news lately. In Finland, many of the pipelines date back to the 1960’s, some being even hundred years old, and similar numbers are also reported in other Nordic countries. It is easy to predict that the need for repairs is going to accelerate in the coming years. How can we prioritise the coming work? Continue reading…

VRT has been involved in hydropower safety development since 2015; co-operating with Finnish dam safety authorities in validating new methods for underwater surveys and serving energy utilities in Northern Europe in underwater structural inspections. Continue reading…
