The intention to purchase a new Multi Role Vessel (MRV) for the Naval Service has been confirmed by the Department of Defence.

This could see the vessel be used as a hospital ship and capable of carrying troops and helicopters for amphibious in addition airborne landings.

A spokeswoman for the department said planning is "underway on this project".

It is envisaged that the MRV (as Afloat reported in 2018) will replace the ageing LÉ Eithne as the Naval Service flagship, and could cost up to €200m.

The new ship is likely to be designed to allow it the capability to carry out numerous different types of missions, not just sea fishery patrols.

Military sources have indicated that it could be used to provide humanitarian aid in times of emergency in Ireland and in other countries where conflicts or climate disaster threaten civilian populations.

It could also be used by gardaí, customs, or the coastguard, where required.

The MRV project is being managed by a civil-military project team and work is ongoing on preparing detailed specification requirements for the ship.

Dublin Port-Douglas sailings in the winter months are operated by Ben-My-Chree, a conventional ferry that only calls to the Irish capital on a handful of sailings during this period, writes Jehan Ashmore.
The Isle of Man Steam Packet Company (IOMSPCo) ferry docked just after midnight at the multi-user ferryport (terminal 1) and departed at around 02.30hrs. She returns to Dublin on the 22 October,17 December and the final sailing for this year is 26 December.

Following this mornings Irish route sailing, she resumed on her regular Douglas-Heysham route and she also serves Douglas-Birkenhead (Liverpool) during the winter months.

During the summer Dublin-Douglas sailings are served by fast-ferry catamaran Manannan (1998/5,743grt). The 96m InCAT built in Hobart,Tasmania had also operated Douglas-Belfast high-season crossings. Her roster is now confined to a Douglas-Liverpool sailing schedule.

Ben-My-Chree (photo) is Manx for 'Girl of my heart' and her island owners commissioned the 12,504grt ro-pax from Dutch shipbuilders Van de Giessen-de Noord. The 125m ferry was launched in 1998 and she can accommodate 630 passengers,275 vehicles and 1,235 freight lane-metres.

This particular ro-pax design has also been built for Channel Islands operator Commodore Ferries with their Commodore Clipper and a Scandinavian ferry operator. In addition another Dutch shipbuilder, Merwede built a multi-support vessel (MRV) derived from the design of Ben-My-Chree for the Royal New Zealand Navy when they commissioned HMNZS Canterbury (L421).

Incidentally the Manannan prior to entering service last year for the IOMSPCo. was for five years chartered initially to the United States Navy but transferred to the United States Army Forces. To read more click 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
