Offshore Wind Accelerator Tender: Subsea Cable Design Study


Call for entries from companies and consortia interested in undertaking a study looking into improved cable designs for bottom-fixed offshore wind farms (OWF) that are fit-for-purpose and optimised for their operating environments.

The key objective of this study is to evaluate and recommend potential improvements to subsea cable designs for bottom-fixed OWF and develop specifications of possible future cables.

Subsea cables for bottom-fixed OWF are generally optimised for static operating environments. Although sections of these cables are laid in dynamic applications; such as cables laid on the seabed subject to movement from currents, and sections of cable between the seabed and the entry to the offshore substation, monopile or J-tube. Improved cable designs could lead to reduced life-cycle costs due to improved reliability and fewer mechanical failures.

This study will also investigate the technical feasibility of surface-laid subsea cables and develop relevant standards and best practice guidelines for improved cable handling.
