Mainport Edge, the name of the Cork-based Irish Mainport Holdings (IMH) newly acquired survey support ship from a shipyard in China last year and since relocated to Europe, is where further upgrade works continue, writes Jehan Ashmore.

As Afloat previously reported the 60m ship was to make a repositioning voyage from Asia to Turkey to undergo further works required by Mainport for its role in the international offshore energy sector. At the end of the year, IMH announced that it had agreed to a multi-million euro equity investment from MML Growth Capital Partners Ireland Limited (“MML”) into Mainport Shipping Limited.

Such investment sees MML become a significant minority shareholder in Mainport alongside IMH, in addition to the funding to initially support the purchase of the newly acquired Mainport Edge for around €16 million.

To recap when Afloat contacted Mainport they said after acquiring the vessel which was 90% completed in 2015, that the remainder of the works were completed by Fujian Mawei Shipbuilding Ltd., and as such, the Mainport Edge will be classified as a 2023 newbuild.

In order to make the new survey support vessel suitable for the offshore wind survey sector, improvements have been made and include planned upgrade works in Turkey, where the latest update from the company, has seen the initial construction of new online and offline survey rooms, have been completed.

Also the construction of a new crane and A-frame has also been completed, and the delivery logistics are now being finalized. All this was conducted in a week, and the fact that the company had three prospective customers visit the ship is an indicator of the charter market from global geo-data specialists in the offshore energy sector.

In the forthcoming weeks a new support base for a remotely operated vessel (ROV) is also to be fitted on board Mainport Edge.

When these works are completed, Mainport will be able to add the vessel to the existing fleet of three survey support vessels that operate on the global charter market. The trio consists of Mainport Cedar, Mainport Pine, and Mainport Geo. The latter 50m vessel was the company’s previous new addition, albeit second-hand, as the former offshore supply ship Oya in 2021 was converted at Cork Dockyard into a survey/scientific vessel specifically to suit the requirements of the offshore renewables sector.

In addition, the holdings group, through a subsidiary, Celtic Tugs Ltd, has three tugs, albeit in the domestic market, based in Cork Harbour and at Foynes on the Shannon Estuary. The Celtic Rebel is currently at the Port of Cork's city-centre quays, whereas the Celtic Fergus and Celtic Treaty provide towage duties at terminals along the Shannon Estuary.

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
