#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that ENI Ireland BV, in conjunction with DCENR/PAD, is scheduled to conduct a 2D seismic survey in the Atlantic waters of the Irish Designated Continental Shelf (as defined under Part VI of UNCLOS).

The planned start of the survey is early June and, weather permitting, will continue until mid-October 2013. The seismic acquisition will be carried out by the seismic vessel M/V BGP Explorer (Call sign HP4919) and will be accompanied at all times by guard vessel M/V South (Call sign PJKE).

This proposed survey consists of 18,000km of a full fold 2D seismic survey in offshore waters beyond the 12-nautical-mile limit, and extends into international (high seas) waters.

The M/V BGP Explorer will travel at a speed of 4-5 knots, towing a single solid 10km streamer located approximately 10m below the surface. Both work vessels will be listening on VHF Channel 16 throughout the project.

All vessels, particularly those engaged in fishing, are requested to give the M/V BGP Explorer and the M/V South a wide berth and keep a sharp lookout in the relevant areas.

For co-ordinates of the seismic survey areas see Marine Notice No 25 of 2013, a PDF of which is available to read or download HERE.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport advises mariners that ENI Ireland BV is scheduled to conduct a 2D seismic survey in the Atlantic waters of the Irish Designated Continental Shelf.

The planned start of the survey is mid-April 2013 and, weather permitting, will continue until mid-October 2013.

The proposed survey consists of 18,000km of a full-fold 2D seismic survey in offshore waters beyond the 12-nautical-mile limit, and extends into international (high seas) waters.

The seismic acquisition will be carried out by the seismic vessel M/V BGP Explorer (Call sign HP4919), which will be accompanied at all times by guard vessel M/V Alk Explorer (Call sign HO2639). In addition, M/V De Vrouw Marie (Call sign HP9974) will act as a supply vessel for the re-supply of materials.

M/V BGP Explorer will tow a single solid 10km streamer. The vessel will travel at 4–5 knots and the streamer will be located approximately 10 metres below the surface. All vessels will be listening on VHF Channel 16 throughout the project.

The notice requests all vessels, particularly those engaged in fishing, to give the M/V BGP Explorer, the M/V Alk Explorer and the supply vessel a wide berth, and keep a sharp lookout in the relevant areas.

Details of co-ordinates for the seismic survey are included in Marine Notice No 13 of 2013, a PDF of which is available to read or download HERE.

Notice of this latest seismic survey comes after the news that the European Commission has sought an explanation from the Government over why it has not conducted environmental impact assessments for such operations in Irish waters, which are a designated whale and dolphin sanctuary.

Meanwhile, another recent Marine Notice advises passenger ship operators of the requirements for vessels engaged in the tendering of passengers between ship and shore.

Full details on the relevant provisions of the Merchant Shipping Acts are included in Marine Notice No 12 of 2013 available HERE.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
