Works to repair damage at the East Pier, Dun Laoghaire Harbour in Dublin Bay, that began last year on coastal defences should be completed in the coming weeks, writes Jehan Ashmore.

According to Dun Laoghaire-Rathdown County Council the works to replenish rock-armour from the damage caused by Storm Emma in 2018 should be completed by the end of March.

As Afloat previously reported a barge laden with 1,700 tonnes of Cornish granite boulders are being used to repair the outside of the East Pier.

Such work to position the rocks where required to shore-up coastal defences, is clearly evident when seen from the shores of Scotsman Bay as the new rocks are grey in colour compared to the surrounding slopes along the East Pier.

It is almost a fortnight since the barge towed by tug, Vanguard, departed Dun Laoghaire Harbour and back to the UK. DLRCoCo also confirmed to Afloat that this was the only shipment used in the project where contractors hired by the council are using heavy machinery.

The machinery involving digger/grabbers had to be tranported by sea (landing craft, James) from within the harbour to the outside of the East Pier due to accessiblility reasons.

#MARITIME MUSEUM-The much awaited re-opening of the Maritime Museum in Dun Laoghaire, Co. Dublin is to take place in April, writes Jehan Ashmore.

The museum which is near to Dun Laoghaire Harbour's East Pier, is to reopen on Tuesday 3rd April between 11am t- 5pm. Throughout the season, these same visiting hours apply Tuesdays to Sundays, though the museum will be closed on Mondays.

To read more about the initial exhibits on display (click HERE) in the apt surroundings of the former Mariners Church, where major and essentail renovation work took place over several years. The museum which is run by the Maritime Institute of Ireland (M.I.I.) celebrated its 70th anniversary last year and with the reopening they can now look forward to a new and exciting era.

Located on High Terrace,  a Cul-de-Sac that links the town's main shopping thoroughfare on Georges Street Upper to The Metals, the pedestrian walkway –is only minutes away from the Dun Laoghaire DART station.

Car parking is limited in the immediate vicinity though there are car-parking facilities nearby in the Pavilion which is accessed along the harbour waterfront (Queens Road) and the Dun Laoghaire Shopping Centre approached from Marine Road.

In addition to visiting the museum the M.I.I. also welcome members and volunteers to assist in hosting lectures, producing newsletters, journals, a library, hosting and supporting commemorations in addition to conducting research and highlighting Irelands maritime heritage.

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
