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.
