Description
CWind, part of the Global Marine Group, was contracted by Western Power Distribution (WPD) to repair the in‑service 33 kV power cable linking the Isles of Scilly to the mainland. Using the specialist cable installation vessel C.S. Sovereign, CWind’s team of cable engineers deployed ROVs to survey the seabed, locate the anchor‑damaged section, recover the cable ends and complete a subsea joint. The repaired section was re‑laid on a shorter, more direct route at around 70 m water depth. The project restored the islands’ grid connection within about a month and included plans for follow‑up surveys and additional protection works on the repaired and re‑laid cable segment.
