VRT inspected a newly build oil jetty and its adjacent seabed. The purpose was to check the quality of the construction and to monitor sediment shift around the jetty.
VRT Finland surveyed the hydropower plants of Edenforsen and Degerforsen for Uniper, a large international energy company. The inspections included the examination of underwater dam structures, earthfill dams and the topography of the water reservoir basin floor.
VRT's sonar scanning offered Lempäälä Water Utility precise 3D data for pipeline maintenance and planning purposes.
VRT Finland helped City of Regensburg manage their underwater assets by inspecting the bridge structures and the riverbed of a 12th-century bridge, the Stone Bridge (Steinerne Brücke), in Germany. The City of Regensburg needed a method for underwater inspections, which could provide more details compared to traditional inspections methods for monitoring the condition of bridge infrastructure.
Because time matters - Port of Turku and VRT continue their co-operation in underwater inspections and 3D data management.
As part of ongoing asset management programme and commitment to maximising the operational life of its assets the Port of Dover employed VRT to survey over 3km of quay wall infrastructure and seabed topography to aid in the detailed inspection of these assets.
VRT Finland surveyed the dam structures of a former flood retention basin, which has later been harnessed also for electricity production, for the Centre for Economic Development, Transport and the Environment for Southern Ostrobothnia in Finland. During the inspection in murky waters, two different dam structures were extensively measured.
VRT Finland inspected the port structures, including two quays and the seabed topography, for Port of Mo i Rana in Norway. The Port of Mo i Rana was planning dredging in the port area, and it was important to investigate the underwater conditions before starting the project. As the survey results provide important baseline information and allow long-term data comparisons, VRT’s service helps the Port of Mo i Rana in different phases of the port’s life-cycle: construction, maintenance and asset management.
VRT has studied the condition of Finnish waterways together with The Finnish transport agency (FTA), since 2012. FTA has been a pioneer in using sonar inspection to facilitate asset management of underwater structures, and the results from VRT are used to schedule future inspection, plan maintenance regimes and reduce the risk related to waterways traffic.
The planned inspection performed in every third year was this time a multibeam sonar survey instead of diving inspection in Port of Oxelösund. The results aid the future maintenance planning and monitoring of changes.
VRT surveyed 10-km of underwater pipelines for Finnish electricity, water and district heat provider Jyväskylä Energy Group. Lasting for four working days, the inspection provides an accurate map of the location and condition of the pipes as well as facilitates future repair work and investments into the network.
A 15-km quay wall inspection utilising VRTs sonar 3D imaging technology for one of Europe's largest inland port operator. And a recent inspection to understand the changes in the underwater assets as well as to ensure sufficient navigational depth.
