Next Geosolutions will perform a detailed marine, geotechnical and UXO survey on behalf of Nexans for CIDAC as part of the Celtic Interconnector project.
These surveys will follow the planned route of the Celtic Interconnector offshore power cable route between the South East Coast of Ireland and the coast of France.
Works will begin on Saturday 29 April (subject to weather and operational constraints) and will take approximately 169 days, of which 26 will be within Irish waters.
The surveys will be conducted by two vessels for both offshore and nearshore operations. The OSV Relume (callsign C6TR4) will be conducting the detailed marine, geotechnical and UXO survey works in the offshore areas and operations will be conducted on a 24-hour basis. Nearshore operations will be conducted by the vessel Deep Volans (callsign PETL) on a 12-hours basis.
Both vessels will display the relevant lights and shapes during periods of restricted manoeuvrability and adhere to COLREGS and all licensing requirements.
During operations both vessels will be running survey lines, and all other vessels operating in the area are requested to leave a wide berth. Both survey vessels will keep a listening watch on VHF Channel 16 and will actively transmit an AIS signal. A listening watch will also be maintained on VTS VHF channels as appropriate.
Maps and coordinates of the survey areas as well as contact details can be found in Marine Notice No 29 of 2023 attached below.
