The flagship of a NATO maritime group is on a courtesy call to Dublin Port along with a German Navy frigate, which Afloat reported also arrived at the capital on Friday, writes Jehan Ashmore.

The Royal Netherlands Navy’s 16,500-displacement-tonne HNLMS Johan de Witt (L801), a Landing Platform Dock (LPD) amphibious warfare ship since September, is serving as the flagship of Standing NATO Maritime Group 1 (SNMG1). The ‘Rotterdam’ class LPD is the second largest vessel of the Dutch Navy, which last month departed Den Helder to fulfill its role for two and a half months for the NATO task force operating in the Baltic Sea and around Western Europe.

However, this afternoon it carried out a charter cruise within the port, having earlier sailed from its winter layover berth in Dun Laoghaire Harbour.Little & large: Towering above the waterline at Dublin Port are HNLMS Johan de Witt and the excursion vessel, St. Bridget, which ceased its seasonal excursions.

Prior to arrival at Dublin, the German Navy’s FGS Hamburg (F220), a ‘Sachsen’-class frigate, recently took part in NATO operations. This is in response to drone incursions over Denmark as part of Operation Baltic Sentry, which aims to counter rising aerial threats in the region.

The day before their Dublin calls, both vessels were in the Irish Sea north of Anglesey, Wales, with the HNLMS Johan de Witt arriving first to the capital, docking close to the Tom Clarke (East-Link) toll bridge. Downriver, the FGS Hamburg had berthed on the south bank of the port.

With more than 170 crew members, HNLMS Johan de Witt is also a most versatile vessel; it can transport army troops along with associated vehicles and dispatch landing craft from the stern-located landing well-dock. (As pictured) are helicopters, which can also be deployed from a hangar and use two landing spots.

HNLMS Johann de Witt was constructed overseas in 2007 on the banks of the Danube in Galati, Romania (likewise the Irish Lights aids to navigation vessel, ILV Granuaile). Whereas the leadship's namesake, HNLMS Rotterdam, was built in 1998 by Damen Schelde Naval Shipyards and is smaller at 12,750 displacement tonnes.

As for the largest vessel of the Dutch Navy, the accolade goes to HNLMS Karel Doorman (A833), an auxiliary replenishment logistic support vessel of 27,800 tons built by the naval division of the Dutch Damen Shipyards Group. It was commissioned in 2015, and as Afloat reported early last year, the 204 m auxiliary called to Belfast and Cork harbours.

Over the years, both amphibious platform landing dock vessels have called at Irish ports. On this latest call, HNLMS Johann de Witt will remain in port over the weekend before departing on Monday. The Dutch LPD is to set off in the morning and be followed by the German frigate at 12 noon.

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.
