The Great Belt Bridge, Storebæltsbroen, connects Sealand and Funen across the Storebælt, and comprises two bridges and a tunnel.
The West Bridge, linking Sprogø to Funen, consists of two separate and parallel bridges, one for the road and one for the railway. The bridge which is approx. 6.6 km long comprises 63 bridge spans placed on 62 bridge piers, all elements constructed in concrete.
In the early days, a monitoring system was installed on the West Bridge for recording longitudinal and transversal displacements of the bridge sections, and further to monitor inclinations of the bridge piers carrying the rail bridge and send warning signals in case of a ship collision.
A complete new Structural Health Monitoring (SHM) system, including sensors, data-loggers and back-end software, was designed, produced and installed.
Krabbenhøft and Ingolfsson was hired as main contractor to carry out the project from concept to final installation for Storebælt A/S.
Design, produce and install a complete, new and modern, SHM system for the West Bridge.
The project was started in early 2015 and scheduled for completion late 2015.
