Afloat reader Lee Maginnis has shared a new image of the suction dredger Charnock returning to Warrenpoint in Co Down after emptying its load in the open sea on Sunday (24 March).

As previously reported on Afloat.ie, the vessel has been carrying out dregding operations in the approaches and deep-water berths of the inner harbour of Warrenpoint Port since the end of February.

These operations are expected to continue until mid April.

Annual maintenance dredging at Warrenpoint Harbour in County Down will continue until the end of March and possibly into April.

According to Afloat reader Lee Maginnis, residents and visitors to Warrenpoint and, indeed, Omeath have been treated to the sight of the trailing suction dredger "Charlock" hard at work over recent weeks.

The dredging, say the harbour authorities, will 'secure the safety and accessibility of the shipping channel for commercial and recreational purposes'.

Since the end of February Charlock has been carrying out operations in the approaches and deep-water berths of the inner harbour of Warrenpoint Port, an operation that will take approximately 48 days.

The sleek, grey ship, with a bulbous bow transports dredged material to the WARRENPOINT B licenced sea disposal site outside the lough.

The Charlock is supported by the "Forth Trojan" workboat vessel, which will undertake bed levelling operations.

Dredging work is about to begin at the Port of Waterford with a maintenance dredging campaign to be carried out by a Dutch company.

Baggerbedrijf De Boer B.V.'s trailing suction hopper dredger Amazone is next week to conduct activities in the vicinity of Belview, Cheekpoint and further down in the estuary at the Duncannon Bar.

The campaign's main objective is the removal of accumulated sediment from the channels, turning areas and berths at (Belview) the main terminal at the Port of Waterford. This work will mostly involve work at the Cheekpoint lower bar and also at the Duncannon Bar.

The removed material will then be disposed by the 2771m3 hopper capacity dredger at an approved site beyond the estuary at a location south west of Hook Head.

It is expected that the campaign will take approximately 28 days and be followed by a bed levelling works by the Fastnet Sound which Afloat adds is a 21m MulitCat operated by a local firm Fastnet Shipping.

The marine plant and services company is based on the River Suir at Bilberry which is just westward of Waterford city's Rice lift-bridge.

One of the country’s leading marinas will become unusable for keelboats unless urgent action is taken to address increasing silting in the harbour area writes David Forsythe in West Cork

Kinsale-based Fine Gael councillor Kevin Murphy told the recent meeting of Cork County Council’s Western Division that the issue was among the most serious he had ever had to bring to the attention of the council.

“The story is that Kinsale Harbour itself has severe silting at the yacht marina and around pier head itself. A substantial number of the keelboats are bottoming out now. This is a very serious issue and a very expensive one to sort out because there is a substantial dredging to be done,” he said.

Matthias Hellstern, Commodore of the Kinsale Yacht Club said that the issue had become much more serious in the last few years and the rate of silting in Kinsale Harbour seemed to be increasing.
“During Covid there was obviously a lot less activity at the marina and in the harbour in general because of the restrictions. It has been happening over a number of years but seems to be getting much worse now. It is something that we really need to address urgently,” he said.

The 200 berth marina brings in some 3,500 visiting boat nights to the town every year contributing an estimated €525,000 to the local economy according to the yacht club’s own estimates. A non-profit organisation run by volunteers, it is one of only three yacht clubs in the country that owns its own marina, the others being Howth Yacht Club and the Royal Cork Yacht Club in Crosshaven.
“We have visitors coming from France, the UK, Spain, Germany, the USA and all around Ireland,” said Matthias Hellstern, “and we run also run national and international sailing championships which we could not do without the marina facility.”

The KYC is due to host the upcoming Squib UK National Championships, Dragon Gold Cup and also hosts the biennial Sovereign’s Cup, but silting is already causing problems for events in Kinsale.
“We hosted the April Spring series recently and we were having yachts running aground at low tide,” said Matthias, “they simply couldn’t get out of the marina and obviously that’s a serious problem.”
Mr Hellstern said that already about 25% of the marina was not useable for keelboats at low tide.

“At the moment we can move things around a bit. The berths furthest from the channel are most affected so we can put power boats, boats without keels in there for the time being but as the silting gets worse more and more of the marina will be affected.”

Cllr Kevin Murphy said that silting was affecting other users of the harbour as well across leisure, fishing and commercial sectors.

“We have to at all times ensure Kinsale continues being useable for leisure and also commercial and fishing, it’s all three. The Kinsale Yacht Club will help out with a survey that needs to be done on the silting and I would expect that the county council will also chip in if we can to help out in their endeavours to get that done as soon as possible.”

Cllr Murphy said that he would put down a notice of motion at the next municipal district meeting to have all of the stakeholders attend a meeting at Kinsale Yacht Club, “to make sure this is addressed as soon as possible”.

Responding to Cllr Murphy, Kevin Morey, Director of Water Services at Cork County Council said, “We will engage just to take stock and see what is the issue there. From your description, it sounds like it might be quite a significant one and we are aware from other locations that that could bring us into quite complex and protracted processes. Let’s start looking first and take stock so we’ll get back to you on that and arrange some kind of assessment on site.”

Environmental campaigners have hit out at a Stormont decision to approve sand dredging in Lough Neagh, as the Belfast Telegraph reports.

Sand dredging has been practiced in Lough Neagh since the 1930s, with no permission needed until after the lough was designated as a Special Protection Area for wildlife in 1999.

Most recently the practice has been subject of a years-long legal battle, as previously reported on Afloat.ie, with Friends of the Earth claiming that as much as 1.5 million tonnes of sand are removed from the lough each year.

The final say on the matter was left to Northern Ireland’s Department of Infrastructure, whose minister Nichola Mallon signed off on the approval and said the decision was a “finely balanced” one “where I had to weigh up the various benefits with the potential for harm to the designation features of the lough”.

Among those criticising the move was Green Party NI leader Clare Bailey.

She said that sand dredging has “a devastating impact on the entire ecosystem of the lough”, and claimed the situation underscored the notion that “Northern Ireland is disintegrating into an environmental wasteland”.

The Dublin Port Company has given notice that maintenance dredging will take place between Alexandra Basin and the Dublin Bay Buoy from tomorrow, Thursday 10 September.

Four weeks of dredging works are scheduled in the fairway and berth pockets from the buoy to a line drawn due south of berth OB1 and including Alexandra Basin East.

Three vessels will be involved in the dredging works: the trailing suction hopper dredger Shoalway; the survey vessel Smit Neyland; and Norma, a bed-levelling plough.

The three craft will maintain a listening watch on VHF Channel 12 and show the required lights and shapes.

All other vessels should pass at slow speed and make due allowance for their operations and restricted manoeuvrability.

The Port of Cork reminds mariners that maintenance dredging will be taking place in Cork Harbour on all main shipping channels and berths from this Wednesday 19 August.

As previously reported on Afloat.ie, the dredging campaign by the TSHD Taccola will progress 24 hours a day until late September.

It follows a prior survey conducted last week, and bed levelling operations which began yesterday, Sunday 16 August.

Mariners are requested to navigate with caution when in the vicinity of the work craft, to pass by as wide a margin as possible and proceed with minimum wash and speed.

A maintenance dredging campaign has begun in recent days at the Port of Waterford where activities will involve the waters of Duncannon Bar, Cheekpoint, and at the port's main terminal at Belview, writes Jehan Ashmore

Prior to the operations at the south-east port, the Cypriot flagged Shoalway, a trailing suction hopper dredger had been carrying out operations for the Dublin Port Company. Shoalway sailed from the capital to arrive on the Waterford Estuary on Sunday. 

According to the Port of Waterford (click to consult campaign notice here), the dredger will dispose spoil at an approved site south west of Hook Head, Co. Wexford. Dredging will be followed by a bed levelling campaign by the vessels, Fastnet Sound and or the Glenesk.

Afloat adds that Irish Dredging which is a subsidiary of Royal Boskalis Westminster nv, the world’s largest dredging group, was given the contract from the Port of Waterford. The extensive fleet of the Dutch group provides Irish Dredging access to the use a of wide range of vessels for projects around the Irish coast.

Further tracking of the Shoalway since introduction on the Waterford Estaury has seen the 90m long dredger kept busy between Cheekpoint to the spoiling grounds out to sea.

The campaign according to the Port of Waterford is expected to last approximately 24 days.

#Irishports - The Port of Waterford have issued a Marine Notice in recent days to advise all ship owners, shipmasters, agents, fishing vessels, pleasure craft users, seafarers and fishery organisations of a dredging campaign, writes Jehan Ashmore.

The dredging operation along Waterford Estuary began in mid-March and according to the south-east multi-modal Port the campaign will continue until around 6 April.

Carrying out these works is the task of trailing suction hopper dredger Freeway which will conduct dredging activities in the vicinity of Belview Port. The lo-lo facility located downriver of Waterford City is the main port along the estuary.

Freeway is operated by UK firm, Royal Boskalis Westminster based in Hampshire. They are no strangers to these waters having been contracted previously by the port and more recently from the Dublin Port Company. Due to berth capacity constraints the 92m dredger during December had to dock in Dun Laoghaire Harbour.

On this occasion, Freeway's role on Waterford Estuary will include duties carried off Cheekpoint and at the Duncannon Bar located further downriver and beyond where the Passage East ferry links to Ballyhack.

Disposal material from Freeway will take place at an approved site south west of Hook Head. Following such work a bed-levelling campaign will be assigned to the Waterford City based catamaran craft Fastnet Sound.

The Department of Agriculture, Food and the Marine has updated local Fingal councillors on its proposals for the dredging of Howth Harbour.

On his Facebook page, Cllr Cian O’Callaghan says the meeting with the department and the Howth Harbour Master on Wednesday (6 March) detailed a plan to dredge five key areas of the harbour, namely:

  • The fishing trawler basin between the West Pier and Middle Pier
  • The approach channel at the mouth of the harbour
  • The marina used by Howth Yacht Club
  • The approach channel to the marina
  • The outer moorings area which is used by the Howth Sailing and Boat Club

This would result in the extraction of 225,000 cubic metres of silt, the equivalent of up to 30,000 lorry loads, says Cllr O’Callaghan.

The detailed plan follows testing of material extracted from the harbour which confirms that while is it contaminated by general harbour activity, it is not considered hazardous.

It is being proposed that the spoil be treated and used to create a 100-metre-wide infill area along the west side of the present West Pier. Plans for the use of this new space have not yet been decided but it is expected there will be a relevant public consultation by year’s end.

Four months ago the tender period closed for engineering services related to these long-awaited dreading works in the North Co Dublin harbour.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
