N-Sea Group have successfully completed a pre-emptive repair to SSEC3. SSEC3 is one of four 132,000 volt export circuits owned and operated by the Gwynt y Môr OFTO, providing the export connection between the Gwynt y Môr Wind Farm and the onshore UK transmission system. The pre-emptive repair was the second stage of a repair to SSEC3 that saw circa 7.5km of submarine cable replaced.

Gwynt y Môr is a 576-Megawatt offshore wind farm located off the coast of North Wales. The wind farm has 160 wind turbines of 150 meters tip height above mean sea level.
