A Sandown-class minehunter of the UK’s Royal Navy, HMS Penzance (M1O6) which departed Oban in west Scotland is on a visit to Dublin Port having arrived this morning, writes Jehan Ashmore.

During the week the 500 displacement tonnes HMS Penzance had been offshore of Newcastle, Co. Down and Afloat continued to track the vessel that reached Lambay Island yesterday.

An overnight anchorage took place off the west side of the island and offshore of Rush in north, Co. Dublin. This morning the 52m minehunter was off Howth Peninsula waiting for a pilot cutter from the port which took place at around 0900hrs, before proceeding into Dublin Bay.

A crew of 40 operate the minehunter which berthed at the North Quay Wall Extension, one of the port’s areas where foreign naval vessels are allocated berths. As routine, the port of call will enable crew rest and recreation. 

HMS Penzance is named after the seaside town of Penzance in Cornwall and was commissioned by the Royal Navy in 1998. Also in service are more of the Sandown-class, HMS Pembroke and HMS Bangor, where the harbour-town on Belfast Lough was visited by HMS Penzance in June as part of the Sea Bangor Festival.

The primary role of HMS Penzance, as part of the First Mine Counter Measures Squadron (MCM1) is to work along the UK coastline, clearing mines to allow safe passage for larger forces. The minehunters also provide an additional layer of protection thanks to their firepower and conduct NATO exercises with other nations.

In 2000 the minehunter was deployed to the Middle East for three years as part of a Mine Countermeasures Squadron based out of Bahrain.

On completion of the call to the Irish capital, a departure on Monday and it is understood HMS Penzance is to return to Oban.

Harland & Wolff shipyard has acquired the former UK Royal Navy HMS Atherstone from the Ministry of Defence (MOD).

HMS Atherstone was launched in 1986 as the Hunt-class Mine Counter-Measures Vessel (MCMV), that is no longer in service.

The acquisition by Harland & Wolff of the vessel is with a view to refurbishing it for non-military uses, discussions for which have already commenced with interested parties.

Harland & Wolff is involved in a competition run by the MOD regeneration programme for the former HMS Quorn (M55). It believes that the acquisition of the former

HMS Atherstone will significantly de-risk the M55 regeneration programme given that the two vessels share a number of spare parts and components.

Should Harland & Wolff be awarded the regeneration programme for the M55, such spare parts and components on the HMS Atherstone will be utilised during the regeneration programme of the M55. It expects negotiations with the MOD on the M55 regeneration programme to be completed in the next few weeks with an announcement to be made thereafter, should an award be made in Harland & Wolff’s favour.

Harland & Wolff, group CEO John Wood, commented: “I am delighted that we have acquired the former HMS Atherstone.

“The benefits of this acquisition are two-fold; we now can significantly de-risk the M55 regeneration programme by utilising spares and component parts common to the two vessels, which has been recognised by MOD and will certainly help in closing out the negotiations over the next few weeks.

“Secondly, we also can utilise this platform as the basis for other clients’ projects, which will be a valuable revenue stream for 2023.

“I am pleased that we have generated a lot of interest for the repurposing of the former HMS Atherstone, and I expect to make announcements in this regard as soon as we have executed a refurbishment contract with a counterparty.”

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.

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

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
