As strollers take in the fresh conditions along Dun Laoghaire Harbour's East Pier today they will see the state's first purpose built oceanographic research vessel RV Celtic Voyager moored alongside at the jetty, writes Jehan Ashmore.
With her distinctive 31m green-painted hull, the 340 gross registerd tonnes (grt) vessel built by the Dutch Damen Shipyard in 1997, was commissioned for the Marine Institute, whose headquarters are based outside Galway city at Oranmore.

RV Celtic Voyager is an inshore RV and she can accommodate 6 - 8 scientists with a maximum endurance of 14 days. According to her intensive survey schedule she is currently conducting hydography work for this month entirely. To read her complete survey programme click HERE.

In 2002 she was joined by a second though considerably larger vessel the 65m RV Celtic Explorer, which is six times larger than her fleetmate in terms of tonnage, which is 2,425grt. Apart from all the scientific and deck machinery she can also handle seven 20-foot containerised laboratories.She has accommodates for 35 personnel, including 19-21 scientists and has an endurance window of 30 days.

The vessel was also built by the same Dutch shipyard and both are owned by the Marine Institute. Ship management of the Galway based pair is provided by P&O Maritime Services (Ireland) Ltd.

In addition the ROV Holland I a deepwater Remotely Operated Vehicle is operated on board the RV Celtic Explorer. The ROV is named after John Phillip Holland from Liscannor, Co. Clare who was an early inventor and builder of submarines. For more information about the ROV which forms as part of tonight's 'Sea2Sky' event in Salthill, Galway, as previously reported on Afloat.ie click HERE.

Today is European Researchers Night, where the ROV will be on display in Galway

During the weekend call of L.E. Eithne to Galway Harbour, the Naval Service flagship shared the mid-west port with a Spanish oceanographic research vessel (RV) and a cargoship,writes Jehan Ashmore.
The port consists of a single basin named the Dún Aengus Dock where the Vigo registered RV Vizconde de Eza (2000/1,401grt) was berthed. The 53m vessel is run by the 'Secrataria General del Mer' (MARM) which is on an assignment to asses the abundance, estimation and distribution patterns of demersal-benthic species in the Porcupine Abyssal Plain. The port is of also the homeport to the Marine Institute RV vessels and their headquarters based in nearby Oranmore.

Also sharing the basin but located closer to the dock gates was Arklow Shipping Ltd's Dutch registered dry-cargo vessel Arklow Surf (2000/2,316grt). The dock is capable of handling more vessels simultaneously and of course used as a host-port of the high-profile Volvo Ocean Race which is due to return next year.

Galway and neighbouring Limerick City with its Ted Russell Dock, are the only dock-gate accessed ports on the island of Ireland. In the case of Galway there is an exception as freight operations are also available from an outer pier on the seaward side of Dún Aengus Dock though only for domestic purposes. From this pier the dedicated Aran Islands freight service is operated by Lasta Mara TEO's Blath na Mara (1983/330grt). As for Limerick, vessels can also berth outside the dock but they tend to be small port-work related craft that use the outer berth on the Shannon Estuary.

The Galway Harbour Company in recent years have proposed plans for a new outer port, to be built in four stages with a completion date set for 2017. This would enable larger deeper drafted vessels such as tankers and cruiseships to dock in the new port. In the meantime cruiseships anchor off Mutton Island. In addition a freight rail-link, berthing for an inshore fishing fleet and a 216 berth marina are proposed.

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.

  • Capacity for 3 x 20ft Containers

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
