Once again, a Spanish Navy presence in Irish waters occurred as two vessels arrived at Dublin Port this afternoon, following a previous visit over the weekend, writes Jehan Ashmore.

The naval visitors comprise the frigate SPS Almirante Juan de Borbón (F102), commissioned in 2003, and the auxiliary replenishment oiler, SPS Patiño (A14), dating to 1995. The frigate was the first to enter Dublin Bay via the Kish Bank, from where it reached the South Burford buoy at mid-afternoon, having picked up a pilot from the pilot boat, DPC Tolka. At the time of writing, the SPS Patiño remained off the Kish Bank, as the ship's scheduled arrival into the bay is 1700. 

Both vessels were built by the Spanish state-owned shipbuilder Navantia (owner of Harland & Wolff) at their Ferrol yard, Galicia, located on the Atlantic of north-west Spain. 

SPS Almirante Juan de Borbón is named after Infante Juan de Borbón, Count of Barcelona, father of the former King of Spain, Juan Carlos I. The frigate is part of the 31st Surface Squadron at Ferrol, an 18th-century compound that continues to serve and provide logistical support to the navy’s 21st-century units. 

The 5,800 displacement ton Álvaro de Bazán class frigate, also known as the F100 class, is a class of Aegis combat system-equipped air defense frigates, of which the 146 m Almirante Juan de Borbón is the second of five, though originally six were planned. It has helicopter capability and has a crew of 201.   

As for the 17,045-ton auxiliary SPS Patiño, it is named after the Spanish navy minister José Patiño Rosales, who reorganised the fleet on the orders of Philip V of Spain. The 166m vessel, also homeported at Ferrol, is a joint design developed with the Royal Netherlands Navy and is similar to HNLMS Amsterdam.  The ship supplies solid stores and fuel for aircraft, has related maintenance workshops, and is equipped with medical facilities.  

A crew complement of 148, 19 aircrew members, and another 20 personnel can be accommodated.

It was last weekend when the frigate SPS Santa María (F81) had called to Dublin at the South Bank Quay, berth 47, where, likewise, today’s frigate arrived with towage assistance. At neighbouring berth 46, this is being allocated to the auxiliary.

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
