Scour Damage at Subsea Cable Crossings
Offshore Wind Consultants Limited (OWC) have witnessed severe scour damage at subsea cable crossings on a number of offshore wind projects and the results can be costly to rectify and also potentially expose cables to high risk until remediation is complete.
The rock berm is designed to minimise risk to the cable by specific selection of rock size and berm side slopes. If the rock berm is designed with a high profile and perpendicular to the main tidal flows, this can lead to uncharacteristic eddies forming on the far side of the rock berm which can potentially create a scour hole. This may result in cable exposure and cable free spans. OWC will present lessons learnt and also outlines methods and details they have used to successfully stabilise these situations.
