33kV Inner Array Grid Cable System

Seaway Offshore Cables was awarded the contract for the turnkey engineering, procurement, installation and commissioning (EPIC) works related to the inner array grid cable system of the Beatrice Offshore Wind Farm (OWF) project as package contractor for Beatrice Offshore Windfarm.

The Beatrice OWF is located approx. 13km of the Caithness coast line in the “Outer” Moray Firth on the north-western point of the Smith Bank within the UK sector of the North Sea. The OWF consists of 84 wind turbine generators, each with a capacity of 7.0 MW and is based on an inner array grid of 91 medium voltage copper core submarine composite cables with a total length of up to 161 km.

The submarine composite cables were manufactured and supplied by JDR Cable Systems and were subsequently installed by Seaway Offshore Cables utilising dedicated in-house resources such as the CLV Seaway Aimery and ISV Seaway Moxie.
