In a recent reconnoitre carried out by members of the Heritage Boat Association (HBA) and the Portlaw Heritage Group, long lost structures of our boating heritage were located and identified.

Four boats of the Heritage Boat Association, including Heritage Barges 68M and 72M, navigated the Clodiagh to Portlaw recently, the first time that barges have moored at the old Quay in 75 years.

They discovered the Portlaw Graving Docks at the Quay and based on the information in some of the historical documents at the Heritage Centre, these may date from as early as the 1820s and been built before the town. On the same site are the remains of a stone workshop and behind the cut stone quay, they found an old cobbled yard and track.

These structures are close to the old Lock Gate, whose design is reputed to be unique in the British Isles. The gate formed the entrance to the Portlaw Canal where raw materials were carried by barge into the Cotton Mill and the finished product was sent from here on the first stage of the journey to countries all over the world.

All concerned were excited about finding these structures which may pre-date the building of the town of Portlaw. Gerry Burke of the Heritage Boat Association stated "Finds like these are not only important to our boating heritage but give us insights into the social aspects of our ancestors and their amazing skills in creating innovative industrial artefacts by hand. It is important they are preserved for both their tourism value and for future generations to appreciate."

Brian Goggin, who writes about Irish Waterways' history, said "Portlaw's foundation as an industrial town is intimately linked with the use of the River Clodiagh, but there is little published information about the navigation or about how boats used it. These new discoveries add an extra dimension to our understanding and extend the boundaries of the area that should be conserved."

The Heritage Boat Association's aspiration is to protect, promote and celebrate the floating heritage on the inland waterways of Ireland. Our floating heritage provides us with a direct link to the past and includes both commercial and pleasure craft that plied the inland waterways.

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
