Investigation of power cable fatigue issues on offshore wind farms

Lead Research Organisation: University of Cambridge
Department Name: Engineering

Abstract

The proposed study will firstly investigate and compare the existing fatigue assessment models and explore the
sensitivity of the estimates to the defining parameters of each model. Specific consideration will be given to
integrated flow-seabed-structure interaction and the fundamental scour problem. Especially, the understanding of
marine scour processes in complex hydrodynamic conditions is important for evaluating design considerations and
estimating structural performance. The study will likely focus on the static cable parts that are not buried on the
seabed, such as the transition pieces between the offshore foundations and substations and the embedment as
well as the dynamic cable parts that touch the seabed. The project will also include an experimental investigation
of the scouring effect on cable fatigue, as well as numerical analysis validated by the experimental results. Finally,
the project may touch upon cable monitoring techniques that could be deployed to give field measurements for
the actual fatigue conditions.
