#DublinPort - Planning permission has been granted for a major dredging scheme at Dublin Port, clearing the final hurdle before works on the proposed new cruise liner terminal for the city.

The application, given the go-ahead by the Environmental Protection Agency (EPA) on Tuesday 13 September, provides for dredging from the North Wall Quay Extension to the -10m Chart Datum contour in Dublin Bay.

It also permits the disposal of dredged material at the existing licensed site west of the Burford Bank – a matter of much controversy this summer due to its location within the special are of conservation from Rockabill to Dalkey Island.

The subsequent Alexandra Basin Redevelopment Project comprises the infilling of the basin at current berths 52 and 53, a deepening of the fairway and a marina protection structure, intended to future-proof the port to accommodate the next generation of cruise liners of more than 300m in length.

Dublin Port's plans advance as Dun Laoghaire awaits the next step in its own harbour masterplan proposals for a modern cruise terminal.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises of the of the dredging of soft material and disposal at sea, drilling and blasting and removal of bedrock, construction of breakwater and revetment and other associated works at Rossaveal Fishery Harbour Centre.

The works by Cronin Millar Consulting Engineers at the Galway Bay fishing harbour will commence on tomorrow Monday 22 August and continue till January 2017.

The first phase of the works, commencing tomorrow, will comprise the construction of a temporary causeway on the foreshore within the dredge site to facilitate excavation of seabed and disposal at a licensed on-shore site.

The second phase of the works, will commence in the coming weeks and will involve a jack-up barge, floating barge, safety boat, personnel boat, split barge and work boats. This will be advised under a second marine notice.

Maps and co-ordinates of the work areas are detailed in Marine Notice No 34 of 2016, a PDF of which is available to read or download HERE.

#LoughNeagh - Environmentalists have branded Northern Ireland a laughing stock for its failure to stop sand dredging in Lough Neagh, as the News Letter reports.

The issue is currently before the High Court after dredging firms appealed NI Environment Minister Mark Durkan's 2015 enforcement notice against the removal of as much as 1.8 million tonnes of sand from Ireland's largest lake.

And the practice has continued unabated, despite planning permission never being granted for sand dredging on the lough, a protected area for wildlife, said Gregory Jones QC on opening the application for judicial review by Friends of the Earth.

“This issue is bringing the planning system in Northern Ireland into ridicule," the charity's counsel told the court. “This is something one would not expect of the most primitive dictatorship.”

#HYC - Howth Yacht Club has posted a draft letter for all club members and harbour users to send to their public representatives highlighting the urgent need to dredge Howth Harbour.

As previously reported on Afloat.ie, levels of silt build-up in the North Co Dublin harbour have accumulated to around 1.5 metres, rendering low-water spring-tide launches impossible.

The Harbour Users Action Group claims that various Governments since the 1980s have passed the buck for responsibility.

As such, the issue should be a priority among Howth voters heading into the General Election later this month.

In other HYC news, the club will host the ISA Cruising Conference on 20 February (more details HERE) a week before the club's race management team attends the ISA Race Officials Conference the at the Green Isle Hotel on 28 February.

The club is also hosting a prizegiving dinner for all Class 3 racing teams tomorrow evening Friday 12 February (contact the office for reservations) and another dinner next month in honour of the club's first commodore WH Boyd on Saturday 12 March, with a talk by Brian Turvey and Afloat.ie's own WM Nixon.

#IrishHarbours - Concerns over rising silt levels in Howth Harbour have made the pages of the Swords Gazette, which quotes the Harbour Users Action Group as saying launches at low water on a spring tide are now impossible.

Not only is the harbour's busy fishing industry under threat, but coastguard and lifeboat rescues – the harbour is home to Howth RNLI – could also be affected.

"The potential for that is very serious," said the group's Brian Turvey, who claims that various Governments have passed the buck for responsibility since the harbour was last dredged in the early 1980s.

"We've got to the stage now where we have about a metre and a half of silt accumulated," he added, noting the problems that poses for boats with deeper keels.

His comments echo a recent statement by local TD Tommy Broughan, who said it is "critical that the harbour does not become unworkable as a result of the build-up of silt".

#IrishHarbours - Concerns expressed by a number of readers to Afloat.ie over fishing activity in Dun Laoghaire's inner harbour have been assuaged by the Dun Laoghaire Harbour Company.

Two trawlers were spotted around noon last Friday (4 December) dragging a full-sized fishing net between them around the inner harbour.

But Dun Laoghaire's acting harbour master Simon Coate has since confirmed to Afloat.ie that the boats in question were fishing with permission for sprat.

Coate added that the forage fish species comes into the harbour in large numbers on a regular basis at this time of year.

Harbour concerns of a different kind have been heard in Howth, with local TD Tommy Broughan taking the Department of the Marine to task over the lack of any timetable or specific funding for dredging the harbour area - where local yacht club users have found conditions getting worse.

In a post on his website, Deputy Broughan said he was "contacted by members of the Howth Harbour Users Action Group who are very concerned about the build-up of silt in the harbour and the damaging effect this is having on all aspects of this important harbour.

"Howth Harbour has not been dredged for decades. I understand it was last dredged in 1981 or 1982 and I do not recall a dredging programme in the harbour in many years representing the area.

"The action group reports that this neglect has led to almost 6ft of silt building up in the harbour and an operational crisis for all the fishing and leisure craft which use it."

While welcoming investment in infrastructural works at the fishery harbour centre, Deputy Broughan underlines that it is "critical that the harbour does not become unworkable as a result of the build-up of silt".

#sligoharbour – Utilising Sligo Harbour to the best affect is the vexed question confronting Sligo County Council who face dredging costs 'in the region of €5m'. The problem is that if the council invested that figure, there is doubt if they could recover that from the Harbour, according to a report of a Council meeting carried by the Sligo Champion.

Councillors were told that the money required for the next stage of Sligo Harbour acquiring its Dumping at Sea Licence was not available. Earlier this year, the Department of the Environment granted a licence under the Foreshore Act to allow the council to undertake dredging works at Sligo Harbour.

The following phase requires the harbour getting a Dumping at Sea Licence from the Environmental Protection Agency.

However, at last week's budget meeting, it became clear that the €12,000 for this phase was not available.

#RosslareDredging - Sospan Dau a Dutch dredger has recently started work in Rosslare Europort where as previously reported, sand of around 100,000m3 is to be removed from the breakwater, writes Jehan Ashmore.

The harbour's port authority in Rosslare Europort, Iarnród Éireann was allocated funding of €1.4m to contract out the works and is to take some three weeks to complete. Previous sand accumulation at the breakwater has normally been just 11,000m3.

The 1978 built Sospan Dau is transferring the dredged sand to an area just outside the low-water off Rosslare Strand. The sand is understood to be expected to be naturally carried ashore and replenish the beach.

The accumulated sand built up at the Wexford port arose due to severe storms within a fortnight during January and February. A buoy was positioned to mark off this restricted area, for photo click here.

Accompanying the 1,546 tonnes trailing suction hopper dredger is the Irish flagged workboat tug Trojan which has carried out many projects among them the construction of the new Kilronan Harbour on Inishmore, Aran Islands.

#CitySmell - Strong smells affecting Cork city for the past four days are being blamed due to dredging works near the city quays.

The Environmental Protection Agency (EPA), which monitors air quality in the city, said the disturbance of marine sediments could give rise to a release of hydrogen sulphide, which would explain the sulphur or rotten eggs odour.

Shoppers, business owners and visitors to Cork have all reported a foul smell at various locations since Saturday. For more on this the Evening Echo has a report.

#ArklowHarbour - Arklow Harbour is set to be dredged for the first time in 15 years this June after a €2.2 million contract for the job with Clare-based L&M Keating Ltd was officially signed earlier this month.

Wicklow News reports that the works were finally approved after a permit from the Environmental Protection Agency (EPA) for dumping an expected 60,000 tonnes of dredged soil from the harbour out at sea.

Arklow mayor Tommy Annesley said the dredging plans, which follow similar works in Wicklow Harbour, showed a “great commitment to the future of Arklow Port”.

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 FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

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.
