Marine Notice: 3D Seismic Survey In Porcupine Basin

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that PGS Geophysical AS, on behalf of Woodside Energy (Ireland) Pty Ltd, is scheduled to carry out a 3D Seismic survey in the Porcupine Basin.

This survey, under Licensing Option 16/14 and named Granuaile, will cover 1,579 sq km and is anticipated to commence in the third week of May. The expected duration is around 35 days, subject to weather.

The survey vessel RV Ramform Vanguard (Callsign C6TU8) is scheduled to carry out the work. The vessel will tow 12 long solid streamers of 7,050m in length, with a separation of 120m and at depth of 20m below the surface of the water.

Active radar transponders and flashing navigation lights will be on the outer streamer tail buoys. The seismic vessel and equipment will traverse along pre-determined lines east-west across the operations area at a speed of approximately 4.5kts.

The seismic vessel will be accompanied by support vessel MV Thor Magni (Callsign C6BH9) and guard vessel MV Thor Chaser (Callsign J8B2384). Fishery liaison officers (FLOs) will be onboard the RV Ramform Vanguard to ensure communications with fishermen are clear and timely.

All vessels engaged on this survey will be listening on VHF Channel 16 at all times throughout the project. All other vessels, particularly those engaged in fishing, are requested to give the RV Ramform Vanguard and her towed equipment a wide berth and keep a sharp lookout in the relevant areas.

Full details of co-ordinates are included in Marine Notice No 20 of 2016, 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.
