A Norwegian naval architect consultancy that has designed the Marine Institute's new research vessel, Afloat.ie reveals is to be named RV Tom Crean after the Irish seaman and polar explorer in Antarctica, writes Jehan Ashmore.

The name chosen for the 52.80m marine research vessel by the M.I. will honour and recognise the famous Co. Kerry born native from Annascaul who was a member of three major expeditions to Antarctica that took place more than century ago. To read more of these considerable achievements they can be read here.

Also the news of the vessel's name breaks away from the M.I's traditional naming nomenclature using the prefix 'Celtic' as used by a pair of existing research vessels.

As Afloat previously reported, €25m has been allocated in the 2021 budget to progress the construction of the vessel which will form a critical part of the Irish State’s maritime infrastructure, and the strategic importance positioned on the edge of the Atlantic Ocean.

RV Tom Crean is to replace the 23 year old RV Celtic Voyager with the newbuild scheduled to be completed in 2022 and be based in Galway Harbour where the port comprises a dock basin. Also in Co. Galway on the outskirts of the mid-west city, is where the Marine Institute has its headquarters based in Oranmore.

Minister for the Marine, Charlie McConalogue commented that the modern research vessel will enable Ireland to address considerable challenges faced by Brexit and the Common Fisheries Policy and climate-induced impacts on our oceans. The research ship will be able to operate in rougher seas and have the use of technology with 'green' credentials. Surveys will be up to 21 days duration and exploration depths down to 3,000m.

The newbuild designated as ST-366 by designers, Skipsteknisk AS based in Ålesund in western Norway, were awarded the work following a EU tender process. The above GCI image visual of the modern yet elegant appearance of RV Tom Crean arises from Afloat consulting the naval designer website, which displays other newbuild projects from the company founded in 1976. Norway, which is rich in fishing grounds has not surprisingly seen Skipsteknisk develop over the decades in designing ice-strengthened factory trawlers as a speciality. 

As also to be seen in the image, the newbuild RV Tom Crean continues to retain the M.I. colours of a green hull and white superstructure of the current Galway based reseach vessel pair, Celtic Voyager and Celtic Explorer. 

As for the accommodation of the RV Tom Crean this will provide for 12 crew and up to 14 scientists. In addition an on board hospital.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilies 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

It is more than a year since the Marine Institute announced the ship's order in December 2019. The new research vessel which is to replace the older 31.40m RV Celtic Voyager (1997) while the larger 65.50m RV Celtic Explorer (2003) remains in service complete with the 'Holland I' deep-water ROV. It should be noted as part of this ship's equipment is a tender craft called Tom Crean.

Both of these M.I research vessels were custom built, with the Celtic Voyager from the Netherlands from where outfitting took place for the Celtic Explorer having been built in Romania. 

This time the order for RV Tom Crean was contracted to the Spanish shipyard of Astilleros Armon Vigo S.A. The north-western Iberian yard is to build Ireland’s new state-of-the-art marine research vessel, which marks a significant milestone with the construction process expected to be completed next year.

In addition to RV Tom Crean's role mentioned above, the newbuild will also be supporting the Government’s national integrated marine plan, Harnessing Our Ocean Wealth, and the national Marine Research and Innovation Strategy.

Asides the Marine Institute headquarters, Galway is also home to P&O Maritime Services which over the years, provides the M.I. research vessels with crewing along with shore staff based in the coastal city.

Cammell Laird a UK shipbuilder on Merseyside, has achieved its final milestone for the RRS Sir David Attenborough by formally handing over the new polar ship to Britain's Natural Environment Research Council (NERC).

The royal research ship (RRS) to be operated by British Antarctic Survey (BAS) will transform UK research in the polar regions. Its missions will be critical for understanding and making sense of our changing climate.

Crews from BAS will spend the next 50 days undergoing intensive training at Holyhead Port, familiarising themselves with the ship and its equipment.

The 15,000 tonne ship will then embark on further operational and scientific trials where the team will test anchoring, manoeuvring, dynamic positioning and helideck landing. Early next year the ship will undertake ice trials in the Arctic, and in November 2021 make its maiden voyage to Antarctica.

As Afloat reported in October RRS Sir David Attenborough began sea trials having departed Cammell Laird’s Birkenhead facility. This stage had marked the culmination of a complex four year build programme that involved more than 1300 local personnel, 70 apprentices and many hundreds of specialist subcontractors and suppliers.

David McGinley, CEO of Cammell Laird Shiprepairers, Shipbuilders, Atlantic & Peninsula Services said: “This handover is the final milestone in what has been the most ambitious project in Cammell Laird’s recent history and we are proud that a vessel built here in the UK will contribute so much to our understanding of climate change.

“It’s also an important opportunity to reflect on the amount of collective expertise, commitment and sheer tenacity that has gone into this build. We’ve worked closely with NERC and BAS throughout and have shown that Cammell Laird is at the forefront of the global shipbuilding industry and ready to deliver future shipbuilding projects here on the River Mersey. We wish RRS Sir David Attenborough good luck and bid her a very, very fond farewell.”

Nigel Bird, Director of Major Programmes at NERC said: “The handover of the RRS Sir David Attenborough marks the end of the beginning. Seven years on from when the design process began, we have the keys to one of the most advanced polar research vessels in the world, and I want every person who has contributed to this extraordinary ship to know how proud UKRI-NERC are.”

Professor Dame Jane Francis, Director of BAS, said: “This exciting moment is a major milestone for us, and a big moment for all those who have spent the past four years working tirelessly to build this incredible vessel. We’ve seen it evolve from a pile of steel into this amazing state-of-the-art ship that’s going to allow us to do science that we’ve never done before.”

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
