Stena Line’s Rosslare-Fishguard route, which was abandoned altogether for nearly six weeks, is still facing difficulties maintaining its southern corridor service between the Irish and Welsh ports.

As the Irish Independent reports, maintenance work at the Welsh port's linkspan berth has meant that the ropax Stena Nordica, which was announced as the “permanent” ferry on the Rosslare-Fishguard route last year, is unable to berth at the port at the moment.

In the meantime, Afloat adds that the ‘Nordica’ is running Dublin-Holyhead sailings, allowing the route’s routine ferries to go for an annual overhaul. The service on the St. George’s Channel was suspended for a number of weeks while the ferry operator carried out a reshuffle, which culminated in a return for the 1981-built Stena Europe. The veteran vessel, which had operated on the route for 21 years after replacing cruiseferry Koningin Beatrix in March 2002, served the Ireland-Wales route up until last July.

There were also mechanical issues, which meant that the suspension of the Rosslare-Fishguard crossing went on for nearly six weeks while the ageing ferry went for repairs at Cammell Laird on Merseyside. On completion of works at the facility’s Tranmere Wet Basin, Afloat tracked the ferry to nearby Liverpool Docks where it remained for short period.

Stena Europe, however, was eventually able to resume service last month. Among recent passengers including those on 'foot' were enthusiastic Welsh rugby fans that travelled the Irish Sea route to enjoy the Wexford pubs for their Six Nations clash with Ireland.

The resumption of the service is welcomed by many; however, there have again been a number of issues that have resulted in major delays and the cancellation of some sailings.

A Clydeside shipyard has new technical problems including issues with 125 miles of cables are posing a further threat to a project to deliver one of the vessels at the centre of Scotland's ferry fiasco.

New nationalised Ferguson Marine analysis reveals that there remains a concern that the number of faults outstanding are a risk to the acceptance of the two vessels currently languishing at their shipyard.

There had been past concerns that a spiralling catalogue of faults with vessels to serious shipyard concerns over whether they will ever see service.

In May, internal documents from nationalised shipyard firm Ferguson Marine admitted a serious risk that minister-controlled ferry owners and procurers Caledonian Maritime Assets Limited may not accept the vessels for the ferry operator CalMac’s lifeline services to Scotland’s island communities. Those concerns remain.

Officially, Glen Sannox and Hull 802, which are due to serve the Clyde and Hebrides ferry network will be delayed until at least next year – over five years later than planned while costs have at least doubled from £97m to £250m.

But a July CMAL update raised further concerns about delivery, saying that a Ferguson Marine project report from May "did not consider the significant threats posed by the continued risk of late able installation".

It said that consideration is only given to the reinstatement of nearly 17 miles of cables removed from Glen Sannox in February.

But it said "no consideration" was given to the main body of cable installation that extended ship-wide totalling 125 miles.

The Herald has much more here on the challenges of the project.

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
