Tarmonbarry’s lifting bridge on the Shannon Navigaton has finally reopened after an extended closure for essential maintenance, Waterways Ireland has confirmed.

Diversions had been in place since early February when the bridge in Co Roscommon was closed for works that eventually required procuring specialist parts from abroad.

The news will come as a relief to southern Shannon boaters who say they have been prevented from participating in rallies in northern reaches due to the closure.

“This has had disastrous consequences for boating on the Shannon so far this season,” one boater told Afloat.ie in recent days. “To date [there has been] very little activity on Lough Ree as boats cannot get down from Carrick, etc, nor can the southern boats make it up north.”

Elsewhere on the inland waterways, Levitstown lifting bridge in Co Kildare on the Barrow Navigation has also reopened following maintenance works.

Waterways Ireland advises masters of vessels on and users of the Shannon Navigation that the closure of Tarmonbarry Bridge will be extended until at least Monday 27 May.

This further delay is due to additional repair works requiring specialist components being manufactured and delivered from international suppliers.

The cross-border body for Ireland’s inland waterways says the parts required are essential to the safe operation of the bridge.

A diversion route remains available via the Camlin River with additional staff being deployed to Clondra Lock to aid vessel movements along the Camlin.

Waterways Ireland advises masters of vessels on and users of the Shannon Navigation that the lifting bridge at Tarmonbarry in Co Roscommon will now reopen on Friday 3 May.

This extension of the bridge’s closure since February is a result of additional repair works required following a bridge strike.

The cross-border body for Ireland’s inland waterways says it apologises for extending this closure “but the additional work is essential to ensure the bridge is safely operational in advance of the bank holiday weekend”.

A diversion route remains available via the Camlin River.

Waterways Ireland advises masters of vessels on the Shannon Navigation that in-river works for the construction of the Killaloe Bypass upper bridge superstructure are progressing as planned and will continue until October 2024.

As previously reported on Afloat.ie, the bridge is being constructed around 1km downstream of the current Killaloe–Ballina bridge.

A buoyed navigational channel continues to be provided for 100 metres either side of the in-river works.

The following plant and equipment will be operating on or overhead the navigation during the upper bridge works:

  • 600t crawler crane set up on the east shore
  • Stabilising crane barge (30m x 23m x 1.88m)
  • 100t crawler crane
  • Tugboat/pusher boat
  • Dumb barge (23m x 9m) and mobile elevated work platforms
  • Safety boat
  • Landing pontoon and gangways

From next Tuesday 2 to Friday 19 April, the final steel girders will be lifted into position in the central spans of the bridge.

This is a heavy lift operation and deemed high-risk work, requiring calm waters for operation of mobile elevated work platforms (MEWP) on barges.

Masters of vessels are requested to proceed at slow speed (5 knots, no wash) with additional caution in the vicinity of the works, and to follow the instructions of the safety boat crew as there are hazards such as bridge piers, steel piles and mooring lines to navigate.

The cross-border body for Ireland’s inland waterways thanks its customers for their cooperation in relation to these works.

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
