Orsted to replace Cable Protection System on WOW04
cable protection system (CPS) has failed on an inter-array cable at WOW04
B16, at the Walney
Extension offshore wind farm.
Ørsted has secured a marine license to replace the faulty CPS.
The new CPS will be installed on top of existing scour protection. The
work details include: the vessel will position itself next to failed CPS
and divers will make their way via an umbilical to the affected array cable,
the existing CPS will be inspected for any loose or recoverable parts,
a tripod will be used to lift the cable for the repair works, ~1 m long
shells will be added around the cable, diver will return to vessel after
completing the repair work.
In its Q1-2021 report, Walney Extension’s developer, Ørsted mentioned
a cable protection system issue on array cables, which impacted up to 10
offshore wind farms across the UK and continental Europe. The issue occurs
when the CPS moves across the scour, abrading the CPS and in the worst-case
scenario causing the cables to fail.
a 659 MW offshore wind farm, located in the Irish sea. The project is a
shared ownership project between Ørsted, PFA and PKA. Walney Extensions
consists 87 turbines, 190 km array cables, and 2 export cables, each 68.3
km long. The wind farm entered full operations in 2018.
