The Department of Transport advises that Hydromaster will undertake a geophysical survey campaign in relation to the Clogherhead Offshore Wind Farm off the coast of Co Louth.

The survey is expected to run from Monday 11 September to Saturday 18 November, subject to operational and weather constraints.

Works will be conducted by the Ros Áine (callsign EIZG5) using multi-beam echo sounders, sub-bottom profilers, side-scan sonars, magnetometers and ultra-high-resolution survey equipment.

Geophysical equipment will be both hull-mounted and towed. Typically, the towed cable lengths will be approximately four times the water depth that the vessel is working in while acquiring survey data.

The work will be conducted during daylight hours only. Throughout operations, the vessel will display the appropriate lights and shapes and will also be restricted in its ability to manoeuvre. Therefore, passing vessels are requested to leave a wide berth.

Radio transmissions will be conducted with other seafarers to notify them of ongoing operations. Mariners are advised to keep continuous watch on VHF radio channel 16 when navigating the area. The survey vessel shall monitor this channel continuously for safety purposes.

Coordinates and a map of the survey area as well as contact details can be found in Marine Notice No 57 of 2023, attached below.

Techworks Marine is deploying three surface buoys with single-point moorings for a metocean survey campaign at the site of the proposed Clogherhead Offshore Wind Farm.

It follows a geophysical survey campaign conducted by Alpha Marine this past summer, as previously reported on Afloat.ie.

These deployments are expected to be completed over a two-day period, at the next available weather window from Sunday 6 November, subject to weather and operational constraints.

Once deployed, the met ocean devices will remain on site for a period of up to 12 months.

The survey campaign will be undertaken within the proposed Clogherhead Offshore Wind Farm site, located some 10km from the Co Louth coast. Detailed coordinates and a map of the survey area are included in Marine Notice No 76 of 2022, attached below.

Three yellow buoys will be deployed, each with a hull diameter of 1.2m and a nominal freeboard of 0.7m. The buoys will display a St Andrew’s Cross day mark, and are fitted with a radar reflector and navigation light with a three nautical mile range, flashing a sequence of five flashes every 20 seconds.

Deployment operations will be conducted by the twin-hulled multi-cat work vessel MPV Skua (callsign 2GDE3).

During works, the vessel will be restricted in its ability to manoeuvre so all other vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations.

Alpha Marine will undertake a geophysical survey campaign in relation to the Clogherhead Offshore Wind Farm off the coast of Co Louth from next Thursday 25 May to Wednesday 27 July.

The survey will be conducted by the Baltic Explorer (callsign LYBW) utilising multibeam echo sounders, sub-bottom profilers, side-scan sonars, magnetometers and ultra-high-resolution survey equipment.

Geophysical equipment will be both hull-mounted and towed. Typically, the towed cable lengths will be about four times the water depth while acquiring survey data.

The work will be conducted on a 24-hour basis and the work vessel will display appropriate lights and signals. Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

All other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Mariners are also asked to note that the start date and the duration of the activity are dependent on weather and work progress.

Coordinates of the survey area and contact details can be found in Marine Notice No 26 of 2022, attached below.
