Summary
Dynamic cables connected to floating platforms undergo repeated bending variations during their lifetime, imposed by platform movement, waves and currents. These bending variations lead to stress variations in the internal components of the cable, which could lead to fatigue failure if the loads over time are too large.
Read more Read lessA curvature sensor has previously been presented [2] and used for successful monitoring of curvature variations in a full-scale fatigue test on a dynamic cable during load conditions representative for operation. Results were found to be in good agreement with expected curvature ranges calculated prior to the tests, as well as measurements from curvature sensors mounted on the outside of the test object.
In this paper results from a similar curvature sensor are presented, now for the first time mounted inside a dynamic cable connected to a floating platform. Results are presented in the form of curvature time series and XY scatter plots, and compared to weather data obtained from the area around the specific floating platform. In addition, a statistical analysis is performed on the sensor data to make a first assessment on the effects of curvature variations, which could be used to calculate fatigue life of the cable.
