Marine Notice: 3D Seismic Survey In Porcupine Basin, September 2014

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DDTTAS) advises that Polarcus DMCC is scheduled to carry out a 3D seismic survey in the Porcupine Basin, southwest coast of Ireland, in early September.

The survey will cover 633 sq km and is is expected to last for around 20 days, subject to weather.

The seismic vessel M/V Polarcus Amani (Call sign C6ZD3) is scheduled to carry out the work. The vessel will be towing 10 cables, each 8.1km long with 150m separation at depth of 14 metres, with a total array width of 1.35km.

A buoy equipped with a radar reflector and navigation strobe light will be deployed at the end of each cable.

The seismic vessel will be accompanied by support vessel M/V Bravo Sapphire (Call sign ZDJY8) and chase vessel M/V Nomad (Call sign EI5298). All work vessels will be listening on VHF Channels 16 and 67.

The seismic vessel in particular will be restricted in its ability to manoeuvre while carrying out the survey so all vessels, particularly those engaged in fishing, are requested to give the M/V Polarcus Amani, her towed equipment, the M/V Bravo Sapphire and the M/V Nomad a wide berth and keep a sharp lookout in the relevant areas.

Co-ordinates for the proposed seismic 3D survey are included in Marine Notice No 52 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.
