Marine Notice: 3D Seismic Survey In South Porcupine Basin

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

The survey, similar to the 2D survey in the Porcupine Basin that continues till October, will cover 7,270 km2 and is anticipated to commence in early July with an expected duration of 121 days, subject to weather.

Co-ordinates for the proposed seismic 3D survey are included in Marine Notice No 36 of 2014, a PDF of which is available to read or download HERE.

The seismic vessel M/V Polarcus Amani (Call sign C6ZD3) is scheduled to carry out the work. The vessel will be towing an array of 10 cables, each 8.1km long, with 150m separation for a total width of 1,350m, at a depth of 14 metres.

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 vessels M/V Nomad (Call sign EI5298) and M/V Ocean Guardian (Call sign EIVX). All vessels will be listening on VHF Channel 16 & 67.

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