Naval Vessels from Home and Abroad Visit Dublin Bay’s Port and Harbour

Two naval vessels were in Dublin Bay’s neighbouring ports during the St. Patrick’s Day Bank Holiday Weekend, where one was quietly on a courtesy call while the other was open to public tours, writes Jehan Ashmore.

Visiting Dublin Port was a German Navy auxiliary replenishment vessel, FGS Main (A515), which arrived in the capital last week after meeting the pilot cutter Dodder near the North Burford Bouy off Howth Peninsula. This involved transferring a pilot on board the fifth of the ‘Elbe’ class replenishment vessels, which support units of the navy while deployed away from home ports.

At just over 100m length overall, FGS Main can carry fuel, provisions, ammunition, and other materials; carry containers; and provide medical services. In addition to featuring an aft heli-pad. A crew of around 40 can increase to almost double when squadron personnel join the auxiliary. The class, each of around 3,586 displacement tons, is named after German rivers where parliaments are located.

On entering the port’s channel fairway, a Dublin Port Company tug, Beaufort, assisted the FGS Main at the bow, while Purple Water Towing’s escort tug, Giano, handled it at the stern. The latter double-ended tug of 60 tons bollard pull (btp) is operated by the Mary’s Abbey-based company in Dublin 7.

Berthing took place at the North Wall Quay Extension, which is familiar to numerous motorist commuters traveling across the Liffey at the Tomas Clarke (East-Link) toll-lift bridge, which separates the working port from the ‘Docklands’ quarter. Lining this stretch of the Liffey is predominantly featuring financial services offices, apartment blocks, hotels and retail facilities near the capital's centre. 

Across the bay at Dun Laoghaire Harbour took place the second year of reviving the St. Patrick’s Day parade held at the coastal town, where berthed at the Carlisle Pier was a Naval Service 90m offshore patrol vessel, OPV90 P60 class LÉ William Butler Yeats (P63).

As the pennant number (P63) would indicate, this OPV represents the third of the P60 class, of which a quartet were built by Backcock Marine & Technology’s Appledore shipyard, Bideford, in North Devon, England.

As Afloat earlier reported, hundreds gathered to queue at the harbour’s Carlisle Pier to take tours of the LÉ William Butler Yeats, which is an updated and lengthened version of the original OPV80 P50 class. They are otherwise known as the ‘Róisín’ class, of which this is the name of the first of the 80m pair, the other being the LÉ Niamh (P52). 

The P60 class was built and fitted out to the highest international standards in terms of safety, equipment fit, technological innovation, and crew comfort, and each of the quartet has a 44-member crew, including 6 officers.

In addition, for enhanced sea-keeping qualities, they have a longer hull to cope with the rigours of the North-east Atlantic Ocean along Ireland’s rugged western seaboard.

Likewise of the P60, the Róisín’ twins were built at the same UK shipyard on the River Torridge estuary, downriver of Bideford but under different owners, Appledore Shipbuilders Ltd. They were succeeded by Babcock International, and in more recent years the dry dock and its covered building hall at Bidna were acquired by the Harland & Wolff Group.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
