Marine Notices: Survey Operations In The Celtic Sea, Off Southwest Coast

11th September 2014
Marine Notices: Survey Operations In The Celtic Sea, Off Southwest Coast

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport advises that Osiris Projects will be carrying out two survey operations along the proposed interconnector route between Ireland and France.

The surveys will extend from the Shoreline at two locations in Co Cork (Ballinwilling Strand main route and Ballycroneen Beach alternative route) across the Celtic Sea to the shoreline at two locations in Northern France (Roscoff main route and Pontusval alternative route).

The first survey operation started on 17 August and is expected to run until 30 September, weather permitting. Survey works will be undertaken on the survey vessel RRS Ernest Shackleton (Callsign ZDLSI).

The vessel will operate on a 24-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The RRS Ernest Shackleton will be towing survey equipment below the surface up to 600m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The second survey operation was expected to start on the Irish side yesterday (10 September) and will run until 20 September, weather permitting. Survey works will be undertaken on the survey vessel MV Proteus (Callsign 2HBL7).

The vessel will operate on a 12-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The corridor width for each landing will be 250 metres from the high water mark to the 10-metre contour, then the corridor will widen to 500 metres as the route moves to France.

The survey vessel may be found running both along the corridor and in the general vicinity of the survey corridor. The vessel will be working between high water and 20 metre contour and in daylight hours only.

The MV Proteus will be towing survey equipment on and below the water surface up to 300m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

Both vessels will be listening on VHF Channel 16 throughout the works. Full details of co-ordinates of the work areas are included in Marine Notice No 55 of 2014, a PDF of which is available to read or download HERE.

Meanwhile, a hydrographic and geophysical survey operation is presently being undertaken by INFOMAR on the RV Celtic Voyager off the southwest coast of Ireland, continuing till 17 September.

The vessel is towing a magnetometer sensor with a single cable of up to 100m in length. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The vessel will display appropriate lights and markers, and will be listening on VHF Channel 16 throughout the project.

Co-ordinates for the bounding box of the survey area are detailed in Marine Notice No 54 of 2014, a PDF of which is available to read or download HERE.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.
