Workers at a Merseyside shipyard which built the UK polar research ship, RRS Sir David Attenborough, have voted to strike in a row over pay and conditions.

Electricians, pipe-fitters and welders and others at Cammell Laird shipyard on Birkenhead, are building submarines and ships for the UK’s Royal Navy.

Of those workers which voted to walk-out, this was around 96%, which represents 75% of the more than 400 union members of the unions, Unite and the GMB which are taking part in the ballot.

More on the story from the Independent.

A recent caller to one of the shipyard’s dry-docks, as Afloat previously reported, was the newly introduced UK-Channel Islands ropax Conder Islander which went for repairs. The ferry has returned to Conder Ferries service and at time of writing is sailing from St. Helier, Jersey to Portsmouth.

It is from the English Channel port where the RRS Sir David Attenborough last month departed on its first Antarctica science mission to study the impact of environmental changes on ecosystems and sea ice.

#DublinSwift- Jonathan Swift, Irish Ferries fastferry returned fresh to the Dublin-Holyhead service this week, following annual drydocking maintenance in Birkenhead, writes Jehan Ashmore.

The central corridor route, which is a distance of 60 nautical miles (111 Kms) takes Jonathan Swift only 1 hour 49 minutes while running at up to 40 knots (80kph). So with each crossing, the Dublin Swift, (her marketing name), consumes 15 tonnes of marine diesel oil and in every year she clocks up an impressive total of 162,000 kms.

As previously reported, the Irish Ferrries fleet took in turn annual dry-docking at Cammel Laird, Birkenhead, where the Austal Auto-Express 86m built catamaran craft completed in Fremantle, western Australia, became the last vessel to receive work out of the company's other Irish Sea vessels, flagship Ulysses and cruiseferry Isle of Inishmore.

Now that Isle of Inishmore is back running Rosslare-Pembroke Dock sailings, previously covered by French routes cruiseferry, Oscar Wilde, which is currently undergoing overhaul in Birkenhead.

Oscar Wilde, a former Scandinavian overnight ferry, is scheduled to launch 2013 sailings, firstly Rosslare-Cherbourg on 27 February followed by the peak-season Rosslare-Roscoff route on 10 May.

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
