With just over a fortnight to go to resumption of Stena Line's Dun Laoghaire-Holyhead fast-craft sailings on 1 April, the route to Wales is to see the larger HSS Stena Explorer return instead of Stena Lynx III, writes Jehan Ashmore.
It was originally planned that the 4,113grt 'Lynx' craft would start the season while the 19,638grt HSS (High Speed Service) fast-craft would take over in June for the summer months.

According to Stena Line over 70% of its passengers business is carried by the HSS Stena Explorer in the high season. It is felt that the 1996 Finnish built fast-craft is better suited for the service due to a loyal customer base which was reflected by repeat bookings and their preference of the HSS craft on the 120 minute (2 hour) route.

A daily single round trip is scheduled with sailings from Dun Laoghaire to Holyhead departing at 13:15hrs. The corresponding sailing from the Anglesey port departs at 10.00hrs and arrives at the Irish port at 12 noon. Sailings will operate through the summer until 13 September.

From there on Stena will make a decision as to its continuing schedule, though it is widely believed that the prospects of the fuel-thirsty, expensive to run HSS fast-craft service are likely to be at an end of an era.

Last month negotiations over the core issue of harbour fees were held between Stena Line and Dun Laoghaire Harbour Company. It is understood that the annual fee of €6.5m was dropped to €2m. The board of the harbour company has given a 'conditional green light' of a new ferry contract to Stena Line to run the service for the next two years with an option of a third year.

The service closed for its seasonal break earlier this year on 5 January with the 'Lynx' going into temporary lay-up at Holyhead's inner harbour to join the HSS Stena Explorer. The HSS had been 'wintering' at the port since September sailings were taken over by the Lynx.

Earlier this month the Stena Lynx III came to Dun Laoghaire to continue her lay-up period. The 1996 Tasmanian built craft will stay there before resuming seasonal sailings between Rosslare-Fishguard in tandem with the conventional ferry Stena Europe.

In the meantime the craft is berthed at the harbour's two-berth ferry terminal at St. Michaels Wharf. The HSS berth is only designed for this type of fast-craft whereas the other berth now occupied by the Lynx was built originally for conventional ferries but was re-configured last year to suit the fast-craft.

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
