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.

This story was updated on Friday 25 November with details of support vessels.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
