#MarineWildlife - The RV Celtic Voyager departed the Port of Cork yesterday (Wednesday 24 October) for ‘Operation Orca’, a 12-day survey of an offshore killer whale community associated with the Northeast Atlantic mackerel fishery.

A team of marine scientists from University College Cork is on board the research vessel that’s headed to waters east of the Orkneys, to study the orcas that feed on mackerel between October and February each year.

“This is the first time a dedicated research vessel will be heading up to study these killer whales and we are hopeful to come back with a lot of data,” said PhD researcher and chief scientist Róisín Pinfield in her introductory blog for the survey.

“We will have cameras, GoPros, drones, underwater hydrophones collecting acoustic data so we can hear the killer whales and a RIB so we can get in close if weather conditions allow. Time to pray to the weather gods to keep the storms away!”

The Scientists@Sea blog will be regularly updated by the Celtic Voyager team once they reach the fishing grounds and begin their survey, which runs till Sunday 4 November.

The crew of sailors, artists, musicians and historians on board Ar Seachrán - who are retracing the famous voyage of St Brendan - were refused permission to land on Skellig Michael, it has emerged.
The Kerryman reports that though some visitors are understood to have landed on the island in recent weeks, the OPW refused the Brendan's Voyage crew on health and safety grounds.
A spokesperson for the OPW said it requires at least 10 days notice to make preparations for any visitors and repair damage to pathways and buildings occurring over the winter months.
Dr Breandán Ó Ciobhán of the voyage party described the news as "very disappointing".

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
