The Monitoring product informs managers continuously about shape changes happening throughout their infrastructure. In one view, the manager can decide where stability and integrity are likely to need inspection with the highest priority. This new generation of infrastructure measurement provides managers with a new level of efficiency and accuracy in their inspection workflow.
Because of their high coverage and their frequency of repeat measurements, these shape change data enable a new level of insight in the dynamics of these objects.
Monitoring: decision support in inspection
The periodic monitoring report provides the user with complete updates of all assets under management. The frequency of the updates depends on the type of satellite data used but is always with an accuracy of millimeters.
The Monitoring product allows for changes on a millimeter scale to be detected. These small changes are often not visible with the naked eye and are thus not easily found by visual inspection, especially not if they occur slowly over long time periods. Nevertheless these slow deformation process can also cause significant damage. Supported by Hansje Brinker’s Monitoring capability, the infrastructure manager can now get an early warning of problems that remain latent otherwise.
Known problem sites: acceleration or not?
By determining the rate of deformation at all locations, Hansje Brinker can track and alert when deformation rates accelerate or exceed pre-defined thresholds. This type of monitoring can also serve as a fast and low cost complement to conventional measurement techniques: problem sites that are already known from in-situ inspection can be characterized and monitored with unprecedented accuracy and much improved coverage.
Identifying new problem sites
Additional problem sites, not previously known – but with deformation patterns analogous to known problem sites – can be readily identified in a timely manner. These sites can then be monitored for known analogous failure modes. This way the periodic monitoring updates provided by Hansje Brinker become an integral part of the inspection and asset management workflow.
