NKT will be carrying out an ROV cable survey of the East-West Interconnector (EWIC) cable on behalf of EirGrid to determine the condition of the cable laid 10 years ago.

The EWIC runs between Deeside in north Wales and Woodland in Co Meath, the marine segment being 187km in length with landfall at North Beach in Rush, Co Dublin.

This survey will run the entire length of the marine cable, with a small section of beach survey, from the beach in Ireland to the beach in Wales. The Irish side of the operation is expected to be completed between this Saturday 26 and Wednesday 30 November, subject to weather and operational constraints.

The geophysical condition survey will comprise a standard multi-beam echo sounder and side-scan sonar survey. Note that no ground truthing, sub-bottom profiling or magnetometry is taking place during this survey.

Works will be conducted by the cable installation vessel NKT Victoria (callsign LAWV7) which will display appropriate lights and signals. It will be supported in the near-shore area by the AMS Adventure and an underwater ROV (within two miles of the coast)/

As the vessel will be limited in its ability to manoeuvre at times when undertaking operations, other vessels are kindly requested to keep a wide berth.

Coordinates and a map of the survey area as well as contact details can be found in Marine Notice No 80 of 2022, attached below.
