Monday 12 November is the final date for receipt of tenders for engineering services for the long-awaited dredging of Howth Harbour.

Howth Yacht Club Commodore Joe McPeake has confirmed the date after contact with the Department of Transport, Tourism and Sport.

It is believed that consultants will be appointed within two weeks of tender closing date, and that they will engage with harbour stakeholders early in the new year to discuss issues such as minimising disruption to harbour operations, including the moorings and marina.

While no clear timeframe is available as yet, Commodore McPeake expects the initial stage towards securing licensing and planning permission to take 12 to 15 months, pending any potential challenges.

Following that, dredging works could take up to 18 months to complete, including works at both piers in Howth.

“As soon as the engineers have been appointed we will seek to meet with them to scope out their plan to methodology and review its implications for us,” said Commodore McPeake, who expects to further update Howth Yacht Club members in February.

#Ports&Shipping - The second largest port in Northern Ireland, Warrenpoint Port, is inviting members of the public and other key stakeholders to comment on proposed changes to how dredged material from the harbour is dealt with.

The Co. Down port currently carries out a major dredging programme every two to five years with material disposed of in the Irish Sea.

However, new plans have been put forward to carry out dredging on a more regular but smaller scale, with material placed at a site in the mouth of Carlingford Lough between Cranfield Point and Greencastle.

Clare Guinness, CEO, Warrenpoint Port said: “In order for the Port to continue to support maritime trade successfully, it must ensure a sufficient water depth is maintained to allow for the safe berthing of vessels, which it does through dredging.

“In anticipation of a rise in trade over the coming years, and to ensure the Port continues to thrive as an economic driver to the local region, a new site for the disposal of dredged material is being proposed within the mouth of Carlingford Lough.

“This is also in line with current thinking that dredged material should be deposited as close as possible to source.

“In our role as a custodian of the marine environment, we want to hear the views of all stakeholders, including members of the public, before any plans are put into action.”

A number of surveys, studies and assessments will be undertaken to determine the suitability of the location between Cranfield Point and Greencastle, including marine ecology and sediment surveys, geophysical surveys, and hydrodynamic and sediment transport modelling.

A public drop-in consultation event will take place at Warrenpoint Town Hall on Wednesday 19th September from 4pm to 7pm. There will be an opportunity to discuss the proposed disposal site and the environmental assessment process with Port staff and its consultants Royal HaskoningDHV.

#DublinBay - The dumping of sewage sludge in deeper waters beyond the Kish Bank “might well serve as a model” for the current dredging of Dublin Port.

In a letter to The Irish Times earlier this week, Cormac F Lowth, a diver and member of the Maritime Institute of Ireland, responds to the claims of Dublin Port Company’s chief regarding the effects of recent dredging operations.

Dublin Port CEO Eamonn O’Reilly defended the dredging operations in the port, citing “the science available to measure its impact” in response to discontent among diving groups over the state of the water in Dublin Bay.

Divers concerned that the dredging is to blame for murky waters, which have seen all planned dives cancelled due to poor visibility, have however “ignored the obvious” and might now look further east for a potential answer to a question that’s left the bay’s crabs and lobsters with ‘an overcoat of silt on their backs’.

Lowth explains that dredging spoil such as that dumped at the Burford Bank at the edge of Dublin Bay contains estuarine mud and fluvial silt that “is not going to remain in toto on the top of this bank”.

“A glance at a tidal atlas for Dublin Bay is enough to convince one that much of anything that gets dumped near the mouth of the bay will get washed back in by the strong tidal currents,” writes Lowth. “This can surely be described as the maritime equivalent of defecating on your own doorstep.”

#DublinBay - Murky seawater in Dublin Bay should not be blamed on dredging, according to Dublin Port Company’s CEO.

Earlier this week, it emerged that all planned diving excursions in Dublin Bay by Irish Underwater Council members had been cancelled due to poor visibility in the water.

Dive instructor Peader Farrell pointed at dredging works to deepen the channels into Dublin Port for rendering the bay’s waters “filthy brown” and leaving crustaceans “with an overcoat of silt on their backs”.

However, in a letter to The Irish times this morning (Thursday 10 May), Dublin Port Company chief executive Eamonn O’Reilly says that the dredging operations that began last year ‘did not cause any discernible increase in turbidity above recorded background levels’, according to the port’s Annual Environmental Report.

“Dredging has been a feature of operations in Dublin Port since the early 20th century,” said O’Reilly.

“We now have the science available to measure its impact and objectively confirm that dredging in Dublin Port does not damage the environment of Dublin Bay.”

#DublinBay - All planned diving expeditions in Dublin Bay have been cancelled due to silt from dredging operations clouding the water, it has been claimed.

The Irish Times reports that Irish Underwater Council members have abandoned all scheduled dives, as a result of poor visibility from particles in the water that have also left lobsters and crabs with “an overcoat of silt on their backs”, according to one diver.

Dredging works to allow larger cargo ships and cruise liners to enter Dublin Port began in October last year, as previously reported on Afloat.ie.

But this dredging has left the waters of Dublin Bay “filthy brown, somewhere between dark chocolate and milk chocolate,” says diving instructor Peadar Farrell. “None of the local scuba diving clubs have been able to start diving as yet in 2018.”

Important dredging work at Hafan Pwllheli marina in North Wales has been scheduled for 2018. The plan to dredge the harbour entrance and the main channel to maintain its design depth has already been agreed. Work on clearing the entrance of silt using land-based machinery will start on 9th April. This is expected to take a few weeks.

The following month a tug boat equipped with bed leveling machinery will be employed to remove any bumps in the main channel that runs through the outer harbour. Dredging will then stop over the summer months to minimise disruption to berth holders.

More extensive dredging of the marina basin itself is then planned for October 2018.​ This was last carried out four years ago when 90,000 cubic metres of dredged material were removed from the harbour.

Wil Williams, Hafan Pwllheli Marina Manager said: "We are pleased to report that dredging of the entrance will begin in April, moving on to the channel levelling work in May. This is routine work and part of our ongoing maintenance programme. During the winter months we can get a build up of silt at the entrance and high spots in the channel. This has to be remedied periodically. Once this is complete, the entrance and channel will be returned to the designed depth of 0.5m below Chart Datum, providing excellent access to the marina for most yachts at virtually all states of the tide.

"Later in the year, we will commence work on dredging the inner harbour and marina basin. This is a major undertaking because boats at the marina will have to be moved to alternative pontoons during each phase of the dredging programme. However, we feel this work is important to ensure that our facilities continue to be of the highest standard."

#portofcork - Along the River Lee is where an expected stink is to eminate in the coming days as the Port of Cork dredges the riverbed.

As the Evening Echo writes, every three years the Port of Cork carries out dredging work in the harbour and the quaysides to maintain the shipping channel. The work disturbs the riverbed, dragging up sediment and releasing gases like hydrogen sulphide. While the gases are safe, they are responsible for the eggy smell that could hang over the river in the coming days.

In 2014, Barrack Street, MacCurtain Street, Shandon, North Main Street, Patrick’s Street and Merchant’s Quay were all affected by the smell as a result of dredging. However, it was thought the lack ro rain and warm temperatures exacerbated the situation at that time.

The current dredging scheme is expected to last until the end of October but the city quays portion is planned to be completed by October 9, limiting the smell in the city centre. The Port of Cork said it is taking measures to limit the impact.

#ShippingReview - Jehan Ashmore reviews the shipping scene from among the following stories of recent weeks.

‘Safe and sustainable’ marine transport and ‘delivery of emergency management services’ have been made a high level goal in the Department of Transport’s Statement of Strategy 2016-2019

UK shipbuilder Cammell Laird saw profits and sales fall last year – but the shipyard on Merseyside where Irish Ferries flagship Ulysses (currently drydocking) remains upbeat to win more contracts.

Ardmore Shipping Corporation the product/chemical tanker operator which has its Principal Operating Office in Cork City has made several appointments to overseas offices.

To prepare for a hard Brexit, Enterprise Ireland is advising firms here amid growing signs the British government may opt to quit the single market in order to regain full control over immigration.

County councillors from all main parties of Dún Laoghaire-Rathdown expressed concern at potential financial liabilities in the transfer of Dún Laoghaire Harbour.

In recent weeks at Rosslare Europort dredger Sospan Dau carried out work within the harbour to remove spoil offshore, benefitting not just ferries but cruiseships and timber trading cargoships.

Arklow Castle was launched in the Netherlands as the third ‘C’ class newbuild of a 10-ship order from ASL. The 5,054dwt cargoship slid into the canal at Ferus Smit shipyard in Westerbroek.

#Dredging - In recent weeks at Rosslare Europort a dredging programme was conducted within the harbour to remove spoil offshore, writes Jehan Ashmore.

Dredging operations were carried out by Sospan Dau and assistance from tug Trojan. The resultant spoil was taken offshore and near the Lucifer Bouy.

The works are to maintain sufficient depths at the ferryport's four (one not used) linkspans located on two piers. Asides the ferry industry, the Wexford port has timber trading cargoships and the first cruiseship, Braemar in two decades called last season. 

In further efforts to attract business the Irish Rail operated port are to waive fees for cruiseships calling during this year's season and up to 2019. 

Ferries sail to Wales and France and in the high season there are four services using three routes. They are operated by just two operators, Irish Ferries and Stena Line. Celtic Link Ferries year-round service to Cherbourg and route ship Celtic Horizon (Stena Horizon docked this afternoon in Rosslare) was acquired almost three years ago (March 2014) by the giant Swedish-owned operator.

At the height of Storm Barbara, the second of this year’s storms, Afloat noted Sospan Dau, the Boskalis operated trailing suction hopper dredger take shelter at Wicklow Port.

This saw the ship berth alongside the South Pier. It is along this breakwater during the Round Ireland Yacht Race is where crowds gather to watch the start of the biennial held event. The last such event was held last year.

#LoughNeagh - Friends of the Earth (FoE) is appealing a ruling against its claims that Stormont is “turning a blind eye” to sand dredging in Lough Neagh, as the News Letter reports.

The environmental group brought the issue before the High Court last summer, when it described NI Environment Minister Mark Durkan’s 2015 decision to issue an enforcement notice against sand dredging, rather than an outright ban, as bringing “Northern Ireland into ridicule”.

As much as 1.5 million tonnes of sand is dredged from the lough each year, the charity has claimed, adding that dreading companies have continued the practice as their own challenge against the enforcement notice is pending with the Planning Appeals Commission.

Sand dredging has been carried out in Lough Neagh since the 1930s, and previously no planing permission was required, though the lough was designated as a Special Protection Area for wildlife in 1999.

In November, a judge rejected FoE’s High Court challenge, but the organisation has now appealed that decision.

“We believe the judge erred in law and didn’t take into account the significance of this major nature reserve,” said the charity’s NI director James Orr.

Dun Laoghaire Harbour Information

Dun Laoghaire Harbour is the second port for Dublin and is located on the south shore of Dublin Bay. Marine uses for this 200-year-old man-made harbour have changed over its lifetime. Originally built as a port of refuge for sailing ships entering the narrow channel at Dublin Port, the harbour has had a continuous ferry link with Wales, and this was the principal activity of the harbour until the service stopped in 2015. In all this time, however, one thing has remained constant, and that is the popularity of sailing and boating from the port, making it Ireland's marine leisure capital with a harbour fleet of between 1,200 -1,600 pleasure craft based at the country's largest marina (800 berths) and its four waterfront yacht clubs.

  • 1817 - Construction of the East Pier to a design by John Rennie began in 1817 with Earl Whitworth Lord Lieutenant of Ireland laying the first stone.
  • 1820 - Rennie had concerns a single pier would be subject to silting, and by 1820 gained support for the construction of the West pier to begin shortly afterwards. When King George IV left Ireland from the harbour in 1820, Dunleary was renamed Kingstown, a name that was to remain in use for nearly 100 years. The harbour was named the Royal Harbour of George the Fourth which seems not to have remained for so long.
  • 1824 - saw over 3,000 boats shelter in the partially completed harbour, but it also saw the beginning of operations off the North Wall which alleviated many of the issues ships were having accessing Dublin Port.
  • 1826 - Kingstown harbour gained the important mail packet service which at the time was under the stewardship of the Admiralty with a wharf completed on the East Pier in the following year. The service was transferred from Howth whose harbour had suffered from silting and the need for frequent dredging.
  • 1831 - Royal Irish Yacht Club founded
  • 1837 - saw the creation of Victoria Wharf, since renamed St. Michael's Wharf with the D&KR extended and a new terminus created convenient to the wharf.[8] The extended line had cut a chord across the old harbour with the landward pool so created later filled in.
  • 1838 - Royal St George Yacht Club founded
  • 1842 - By this time the largest man-made harbour in Western Europe had been completed with the construction of the East Pier lighthouse.
  • 1855 - The harbour was further enhanced by the completion of Traders Wharf in 1855 and Carlisle Pier in 1856. The mid-1850s also saw the completion of the West Pier lighthouse. The railway was connected to Bray in 1856
  • 1871 - National Yacht Club founded
  • 1884 - Dublin Bay Sailing Club founded
  • 1918 - The Mailboat, “The RMS Leinster” sailed out of Dún Laoghaire with 685 people on board. 22 were post office workers sorting the mail; 70 were crew and the vast majority of the passengers were soldiers returning to the battlefields of World War I. The ship was torpedoed by a German U-boat near the Kish lighthouse killing many of those onboard.
  • 1920 - Kingstown reverted to the name Dún Laoghaire in 1920 and in 1924 the harbour was officially renamed "Dun Laoghaire Harbour"
  • 1944 - a diaphone fog signal was installed at the East Pier

It has no clubhouse of its own but operates through the clubs with two x Committee vessels and a starters hut on the West Pier. Read the latest DBSC news here.

The sailing community is a key stakeholder in Dún Laoghaire. The clubs attract many visitors from home and abroad and attract major international sailing events to the harbour.

 

Dun Laoghaire Regatta

Dun Laoghaire's biennial town regatta was started in 2005 as a joint cooperation by the town's major yacht clubs. It was an immediate success and is now in its eighth edition and has become Ireland's biggest sailing event. The combined club's regatta is held in the first week of July.

  • Attracts 500 boats and more from overseas and around the country
  • Four-day championship involving 2,500 sailors with supporting family and friends
  • Economic study carried out by the Irish Marine Federation estimated the economic value of the 2009 Regatta at €2.5 million

The dates for the 2021 edition of Ireland's biggest sailing event on Dublin Bay is: 8-11 July 2021. More details here

Dun Laoghaire-Dingle Offshore Race

The biennial Dun Laoghaire to Dingle race is a 320-miles race down the East coast of Ireland, across the south coast and into Dingle harbour in County Kerry. The latest news on the Dun Laoghaire to Dingle Race can be found by clicking on the link here. The race is organised by the National Yacht Club.

The 2021 Race will start from the National Yacht Club on Wednesday 9th, June 2021.

Round Ireland Yacht Race

This is a Wicklow Sailing Club race but in 2013 the Garden County Club made an arrangement that sees see entries berthed at the RIYC in Dun Laoghaire Harbour for scrutineering prior to the biennial 704–mile race start off Wicklow harbour. Larger boats have been unable to berth in the confines of Wicklow harbour, a factor WSC believes has restricted the growth of the Round Ireland fleet. 'It means we can now encourage larger boats that have shown an interest in competing but we have been unable to cater for in Wicklow' harbour, WSC Commodore Peter Shearer told Afloat.ie here. The race also holds a pre-ace launch party at the Royal Irish Yacht Club.
