Spring 2016, At the offshore wind farm Nobelwind in Belgian waters, a scientific condition monitoring system was installed to measure the bending curves in four axes on three monopiles as well as earth pressures and pore water pressures in the direction of the main soil reaction during operation. IGB-TUBS installed earth pressure transducers, pore water pressure transducers and inclinometers in different measuring sections on outside of the monopile. The Belgian company Com&Sens installed fiber optical strain gauges on the inside of the monopiles.

Com&Sens used their robuust optical fibre sensor technology for quick and reliable installation (integrated in a composite). 

 All sensors and sensor cables were covered by steel profiles on the part of the pile which was afterwards hammered into the seebed.
