N-Sea Group has successfully completed a pre-emptive repair to subsea cabling forming part of the transmission infrastructure owned by the offshore transmission owner (OFTO) for the Gwynt y Môr wind farm.
The repair was made to subsea cable export 3 (SSEC3), which is one of four 132,000 volt export wires, owned and operated by the Gwynt y Môr OFTO.
It forms part of the subsea electrical infrastructure providing the export connection between the 576MW Gwynt y Môr offshore wind farm, off North Wales, and the onshore UK transmission system.
The pre-emptive repair was the second stage of a repair to SSEC3 that saw circa 7.5 km of submarine cable replaced.
The repair was executed with the Neptune NP459, a versatile, multi-purpose pontoon of 82.5 metres in length, a beam of 27 metres and a depth of six metres.
“We are very proud that we achieved this great milestone.
“We would like to thank our client and the entire team involved in this great team effort to complete the project in a prudent, efficient and safe way.,” said Rick van Bruggen, Commercial Director Subsea Cables, at N-Sea.
The Gwynt-y-Môr OFTO stated: “We are pleased that this second stage of the repair to SSEC3 has been completed and the circuit returned to full availability.”
