Greenlink Interconnector Ltd (GIL) is proposing to develop an electricity interconnector between the southeast of Ireland, from Great Island in Co Wexford, to southwest Wales at Pembroke.

As part of these proposals, a pre-construction survey is expected to be carried out from today, Saturday 16 July to Tuesday 2 August, weather permitting.

The survey works will be conducted by the Geo Ocean V (callsign: 5BWE3), a multi-disciplined offshore survey vessel with hybrid propulsion fitted for geophysical and geotechnical survey work.

The vessel will have stern deployed equipment and will be restricted in manoeuvrability. All other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Throughout operations the Geo Ocean V will display all appropriate lights and shapes and will be listening to VHF Channel 16 but can set any other channel as required.

For coordinates and a map of the survey location as well as contact details, see Marine Notice No 45 of 2022 attached below.
