6th European Workshop on Structural Health Monitoring. Dresden. Germany. 2012. Report. Cooling towers are essential for the performance and availability of industrial production units. Always higher, they are made up of a fine and light reinforced concrete shell. Their preventive and predictive maintenance is necessary to extend their lifespan but their accessibility remains difficult. Issued directly from SITES 25- year experience in the implementation of remote methods of investigation based on the follow-up of visual and dimensional defects on these structures, SCANSITES 3D® is now the tool of reference for the diagnosis, follow-up and monitoring of cooling tower using current technologies.
