Marine Notices No 37 of 2021 and No 44 of 2021 advised of the deployment of two wave buoys and one floating LiDAR buoy at the Dublin Array offshore wind farm on the Bray and Kish Banks.

The two wave buoys were recovered from site in June 2022. Now the Department of Transport has now been advised by Partrac Ltd that the floating LiDAR buoy on Bray Bank is scheduled to be recovered in the period between Thursday 5 and Thursday 19 January 2023, subject to weather and operational constraints.

The floating LiDAR buoy at Latitude 53° 10.645’ N, Longitude 005° 55.785' W has a square footprint with an area of 4 sqm and height of around 4m above the water line. It is yellow in colour and has a St Andrew cross on top.

It also contains a yellow light which emits five flashes every 20 seconds and is visible for up to three nautical miles.

The vessel CT Barnston (callsign MUZU5) will recover the buoy and tow it back to Wicklow Harbour for demobilisation. Dublin Port will be contacted in advance regarding the operations with estimated timings. The buoy will be towed some 30m astern of the CT Branston at a maximum speed of 3.5 knots.

During recovery of the floating LiDAR buoy on Bray Bank, the vessel will be restricted in its ability to manoeuvre. All other vessels are requested to leave a wide berth during the recovery and towing operations. Radio transmissions will be conducted with VTS and other seafarers to notify them of the buoy operations.

Contact details can be found in Marine Notice No 85 of 2022, attached below.

More works are scheduled for the Codling Wind Park project, with the deployment of two lidar buoys to characterise the wind park area from this week.

Weather permitting, the Voe Vanguard (callsign MBEN9) will deploy the buoys in the Irish Sea off Co Wicklow between tomorrow, Tuesday 27 April and Friday 14 May.

Deployment operations will be conducted on a 12-hour basis. The Voe Vanguard will be restricted in ability to manoeuvre, so all vessels operating within its work area are requested to keep their distance, maintaining a safety zone around the survey vessel and pass at minimum speed to reduce vessel wash.

Throughout survey operations, the Voe Vanguard will be displaying appropriate lights and shapes. The lantern on the buoys will give out five yellow flashes every 20 seconds, visible for up to three nautical miles.

Further details including the relevant coordinates are included in Marine Notice No 29 of 2021, which is available to download below.

The latest notice follows previous advisories for geophysical surveys and geotechnical surveys over the next number of weeks for the wind farm scheme at the Codling Bank.

Published in Coastal Notes

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.
