#MarineNotice - The survey vessel VOS Sweet (Callsign PCPE) is currently conducting offshore geotechnical and environmental survey operations associated with the proposed Celtic Interconnector on behalf of EirGrid.
The VOS Sweet was set to commence operations yesterday, Monday 18 June, and will operate on a 24-hour daily basis for approximately two weeks in two main corridors off East Cork to three landfall points: Ballinwilling Strand (Ballycotton Bay); Redbarn Beach and Claycastle Beach (Youghal Bay).
The survey is to collect geotechnical data utilising a Vibrocorer (VC) and Cone Penetration Test (CPT) spread and environmental (benthic) data utilising Grab Sampler spread. The survey will be conducted under Foreshore Licence FS006811. Common frequency VHF Channel 16 shall be used throughout the project.
Details of the route centreline co-ordinates as well as intended locations for the VC, CPT and benthic sampling are included in Marine Notice No 26 of 2018, a PDF of which is available to read or download HERE.
Meanwhile, Providence Resources is carrying out a site survey on its FEL 6/14 licence, called Newgrange, situated between the Southern Porcupine and Goban Spur Basins some 260km off the South West Coast.
The eight-day geophysical survey by the MV Kommandor (Callsign MCJO2), was scheduled to commence on Monday, is using dual-frequency side scan sonar, single-beam and multi‐beam echosounders, side scan sonar, sub‐bottom profilers and magnetometer.
Seabed (benthic) samples will also be taken using a box corer or grab as appropriate, and geotechnical sampling will be undertaken with a piston corer to a minimum target depth of 6m below the seabed.
In addition to the above, and to accurately determine potential future drilling hazards over the Newgrange location, the proposed survey will also include a high resolution 2D seismic which is not expected to exceed two days.
Survey operations will be conducted on a 24-hour basis. The MV Kommandor will be displaying shapes and lights prescribed in the International Rules for the Prevention of Collisions at Sea (COLREGS) Rule 27, to indicate that the survey vessel is restricted in its ability to manoeuvre. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.
Co-ordinates and a map of the expected working area are outlined in Marine Notice No 25 of 2018, a PDF of which is available to read or download HERE.
