#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.

#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.

Other recent Marine Notices cover outfall pipeline remedial works ongoing at the Corrib gas field, and information on the carriage of inflatable life rafts on small fishing vessels under 15m.

#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.
