A former US Navy vessel USS Joint Venture (HSV-XI) is set to return for a second season operating Douglas-Dublin Port sailings this Friday, writes Jehan Ashmore.
The first sailing of the year from the Isle of Man sees the use of the fast-ferry catamaran craft now renamed Manannan running on the 2-hour 55 minute crossing to the capital.

Manannan's chequered career included a five year charter initially to the United States Navy but transferred to the United States Army Forces between 2001-2006. The 5,029grt craft (see photo) was used for various trials and demonstrations and in which saw service in the Persian Gulf in support of 'Operation Iraqi Freedom' and in 2003 'Operation Enduring Freedom' in the Horn of Africa.

An engine plant of 4 x Caterpillars diesel generates a speed of over 40 knots / 46 mph which provided logistical solutions by the High-Speed Vessel (HSV) to transport troops and supplies covering long distances in support of the Combined Joint Task Force.

Other tasks required by the force included the roles of operating as a mobile command centre which entailed working closely inshore and operating as a helicopter carrier. Helicopters landed at the craft's stern positioned helicopter landing deck.

The military role of the craft is in stark contrast compared to when the 96m ferry was launched in 1998 for civilian purposes as the Incat 050, the number representing the number of pioneering wave-piercing craft built by InCat in Hobart, Tasmania.

Asides her military days the 800-passenger / 200 vehicle fast-ferry has served the Hobart-Melbourne route, between New Zealand's north and south island and in European waters in the Mediterrean and to the Canary Islands.

Manannan (see photo) entered service last May after the Isle of Man Steam Packet Company (IOMSPco) purchased the vessel which was laid-up in Hobart. She made the long delivery to the northern hemisphere and was re-converted for ferry usesage during a refit in Portsmouth.

The 181 year-old company is the only sea-based passenger operator to the island on services linking Dublin, Belfast, Heysham, Liverpool and (Birkenhead) in the winter months.

There are rival companies such as the Ramsey Steamship Company but they are freight-only operators mostly running to Belfast and Liverpool using short-sea coastal traders and to other small Irish Sea ports.

An annual round island cruise is held and like last year the Manannan will be serving the cruise on Sunday 1 May departing Douglas at 11am for a journey of around 2 hours. The route closely circumnavigates the spectacular Manx coastline. For information on the island cruise and fares click here.

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
