Following survey works earlier this year, Lir Offshore Array will be completing geophysical survey works in the Irish Sea off counties Louth, Meath and Dublin as part of a scientific data-gathering exercise over the next six weeks.

Survey company Ondine will be carrying out these survey works on a 24/7 basis from Friday 1 July to Monday 15 August 2022, subject to weather.

Operations will be conducted by the research vessels DP1 Kommandor Iona (callsign GAAK) and DP1 Ondine Jule (callsign EIZH4), the latter of which will start work later in the campaign.

These work vessels will be towing geophysical equipment during operations at the offshore wind farm site and they will be restricted in their ability to manoeuvre.

All other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash. Radio transmissions will be conducted with other seafarers to notify them of the operations.

Contact details, coordinates and a map of the survey area can be found in Marine Notice No 43 of 2022, attached below.

Geophysical survey works as part of a scientific data-gathering exercise for the Lir Offshore Array are set to begin this week.

A research vessel, DP1 Kommandor Iona (callsign GAAK) will be used to carry out the work on a 24/7 basis. The vessel will be towing geophysical equipment during operations and the vessel will be restricted in its ability to manoeuvre.

Coordinates and maps of the survey area are included in Marine Notice No 09 of 2022, which can be found attached below.
