Long Term Monitoring of an All-Composite Water Lock Using Fibre Optics
In the work, we discuss on the use of FBGs to monitor the behavior of an allcomposite water lock which is installed in the Wilhelmina canal in Tilburg, The Netherlands. To our knowledge this is one of the tallest composite water lock in the world and is produced by FiberCore Europe, the main contractor is Heijmans. Main advantages of composite water locks are that they are as light as water, so when submersed no extra force is acting on the hinges and they are durable, corrosion resistant and maintenance free. It is shown that a fibre optic sensor network was successfully embedded in an real all-composite water lock fabricated using a resin infusion technique, with 100% of the sensor lines working after installation. It is shown that fibre optic sensing technology offers the possibility of monitoring the (in-situ) response of composite materials during production, factory testing (validation) and the composite structural response during operation.
