Energia intends to deploy marine acoustic monitoring equipment off the coasts of Co Waterford and Co Wexford between now and 24 February, subject to weather and operational constraints.

The deployments are part of works for Energia’s North Celtic Sea and South Irish Sea offshore wind projects in these respective areas.

The North Celtic Sea is a renewable energy project proposed to be located a minimum of 10km and up to 25km off the Co Waterford Coast. The South Irish Sea project, meanwhile, is proposed to be located a minimum of 10km and up to 25km off the coasts of Wexford and south Wicklow.

Acoustic monitoring equipment will remain on site for a period of three to four months, weather window permitting. After this period the devices will be retrieved and redeployed at new locations, that will continue to cover a 12-month period.

The equipment consists of four acoustic devices and their moorings, which will be used to monitor for marine mammal activity in the proposed wind park areas.

Deployments in both areas will be conducted by the MV Sharp Shooter (callsign EI5069). As this vessel will be deploying survey equipment, it will be restricted in its ability to manoeuvre. All other vessels are requested to leave a wide berth during the operations and pass at minimum speed to reduce vessel wash.

The MV Sharp Shooter will be monitoring VHF Channel 16 and Working on VHF Channel 6. All operations will be during the hours of daylight only. Throughout survey operations, the vessels will be displaying the appropriate lights and shapes.

For more on the acoustic devices, their planned locations, relevant maps and contact details, see Marine Notice No 5 of 2023 and Marine Notice No 6 of 2023, attached below.

Ocean Infinity is undertaking a geophysical site survey campaign for the South Irish Sea offshore wind farm from today, Thursday 14 July to 30 August 2022, weather allowing.

The survey works will be conducted on a 24-hour basis by the Northern Maria (callsign OZAV2) using a hull-mounted multi-beam sonar and sub bottom profiler, along with a towed side-scan sonar and piggy-backed magnetometer (tow max 320m) and ultra high resolution survey equipment.

During operations, the Northern Maria will be restricted in its ability to manoeuvre and will display the appropriate day shapes and lights. All other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Coordinates of the survey area and further details can be found in Marine Notice No 46 of 2022, attached below.

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
