Down On Derg

For the last couple of years, we've done some long-distance boating; indeed in 2011 we didn't get to Lough Derg until the end of September. So we decided that, this year, we were not going anywhere north of Portumna: we would spend the year down on Derg.

Here are some of my impressions of the season. Some of them I may be able to check later, by looking for statistics or reports; some can't be checked because there are no statistics.

 

Weather

My first impression is that summer ended some time around May, with relatively little sunshine after that.

Even the nature of bad weather seems to have changed: the Royal Canal ran out of water in Spring but the Shannon had rather a lot of water throughout the summer. From time to time reports came from upstream of strong flows that made navigation difficult; down on Derg, Killaloe seemed to have strong currents quite a lot of the time, with water being pulled down the headrace to Ardnacrusha.

Met Éireann's report for the summer (June, July, August) seems to support that view: rainfall above average, sunshine and temperatures below average. It also seemed to me that we had more northerly winds than usual: the south-westerlies didn't seem to be the prevailing winds. However, the report says nothing about winds.

 

Numbers

My second impression is that lots of people have disappeared: that very few boats were moving on the lake this year: it was as if we were back to the early 1980s. I'll get the traffic figures from Waterways Ireland later: they cover only passages through locks and moving bridges, so they don't say anything directly about lake traffic, but they do give an idea of volumes.

Now, I may not be the best judge of numbers of boat movements because, if I hear there's a big boaty event on, I go somewhere else. But there seemed to be times when there was nothing moving on the middle of the lake, except sailing boats racing from Dromineer, Garrykennedy or Mountshannon. There weren't even many jetskis or speedboats around.

There were rumours of larger boats being sold to overseas buyers and transported out of the country, but I don't know how to check that. Even checking the total number of Shannon boat registrations wouldn't help: as there is no annual registration fee, there is no incentive for former owners to de-register boats that have been sold.

 

Dromineer

My third impression is that shore-based activity has diminished too.

As we keep our boat in the Shannon Sailing marina in Dromineer, we don't often use the public harbour, but we drive by it en route to the marina. It seemed to me to be pretty lifeless. Numbers of visiting boats seemed to be down (while numbers of resident boats rose), as did numbers visiting by land. (I don't know of any source of statistics for this; if there is one I'd like to know.)

I imagine that the poor weather kept land visitors away, except on the few sunny days. But I don't think that the improvements made a few years ago — path, pebbles, seats and so on — have done much to attract people. Dromineer needs to do more to establish itself as a place to visit, with things for people to do when they get there.

 

Harbour hoggers

My fourth impression is that harbour-hogging — leaving boats in public harbours for more than the permitted numbers of days, instead of paying for berths in private marinas — is on the increase. I don't know of any statistics on this, although I suspect that Waterways Ireland may have some. Its staff do patrol the harbours and record registration numbers, occasionally applying stickers to errant boats, so I imagine that they keep records of the numbers.

The problem is that WI has very little power, under the current bye-laws, to do anything effective. It needs a simple, cheap method of imposing ever-increasing charges on harbour-hoggers — and of enforcing payment. Experience with both the household charge and the mineral oil tax suggests that drastic steps may be required.

 

Other privatisers

The same may apply to other services that WI provides. Its very welcome supply of electricity can at least be controlled, with charges paid by card. However, I suspect that, when water charges are introduced, WI will have to devise a method of charging for water. Whether or not it wants to subsidise boaters, it is unlikely to want to supply folk who drive to its harbours to fill barrels and bottles with water (I have photographed folk doing just that).

And then there's the rubbish problem. Bins have been removed from some harbours on the west side of Lough Derg; a WI notice says that it has a "Leave No Trace" policy, or some such thing. That doesn't explain why there are still bins at harbours on the east side; I suspect that the explanation is in different arrangements with different local authorities. However, overseas tourists (if there are any) are likely to find it a little inconvenient to bring their holiday rubbish home with them, especially if they're flying by Ryanair.

But you can see WI's problem: if it makes free bins available, folk will drive from miles around to avoid paying charges. So, given that Irish folk are unlikely to develop civic-mindedness in the near future, the best solution is to use smart-card controlled bins, with each opening of the lid traceable to the individual boat-owner (or camper-van-owner). The same cards could control the other services and provide WI with a way of tracing user movements.

 

Supply and demand

The problem with free services is that they're too good to last: the provider, especially if it gets its money from an overstretched state, eventually realises it can't continue to provide them for nothing. So, just as declining income and other pressures reduce demand for its product, Waterways Ireland may find itself imposing extra charges that further reduce demand. It is not clear that any marketing campaign can compensate for the economic pressures on the sector.

Controlling The Canals

I wrote recently that the terms of Waterways Ireland's licence agreement for the "Extended Term Serviced Mooring Vacancies" at Shannon Harbour could be easily adapted for use elsewhere on the canals. That might allow WI to begin to bring the long-term berthers, residential or otherwise, under control. And so it proves. We have received this press release from Waterways Ireland.

 

WI Press Release

Waterways Ireland has recognised that many boat owners wish to stay for a more extended period in a single location than the 5 days the annual Canal Mooring and Passage Permit (under the Canals Act, 1986 (Bye-laws), 1988) currently allows.

In response, Waterways Ireland intends to issue an Extended Mooring Licence granting a boat owner the right to leave their boat in one location for longer than 5 days. This permit will enable the holder to moor in a position allocated by Waterways Ireland on a soft bank area of navigation property for a period of up to 1 year. The Extended Mooring Licence will cost e152 per annum.

The application process for the Extended Mooring Licence will open in the autumn when all existing permit holders will be contacted.

All boat owners will still require an annual Canal Mooring and Passage Permit allowing the holder to cruise and pass through locks. Boat owners with a Canal Mooring and Passage Permit proposing to stay longer in one location than 5 days can then apply for the Extended Mooring Licence. The total fee to hold both the Permit and the Licence in 2012/2013 will be e278.

For boat owners with the Canal Mooring and Passage Permit who do not hold an Extended Mooring Licence, the 5-day rule (in the one place or within 500m of that location) will still apply. Waterways Ireland will enforce this bye-law from autumn 2012.

Waterways Ireland will be contacting permit holders regularly between now and autumn 2012 to ensure they are kept up to date with the roll-out of the new permit. All queries about the enforcement of the current bye-laws or the Extended Mooring Licence should be directed to Shane Anderson, Assistant Inspector of Navigation: Tel no +353 (0)87 286 5726, Email [email protected].

These changes are necessary steps to improve the management of the canals and waterway amenities for both the navigational and recreational user, so that investment in the new infrastructure and facilities which Waterways Ireland has undertaken is maximised for every user.

Comment

About time too. I welcome this development: WI has to be able to control who uses its waterways and the uses they make of them.

The proposed charge is surprisingly modest. It is the same for all areas, those of high and of low demand: it might have been difficult to implement differential charging. However, the new licence does not apply to hard-edged areas; I presume therefore that WI intends to keep them clear for visitors.

It is significant that the new control mechanism is a licence, not a permit. Waterways Ireland had been hoping to bring in a single set of bye-laws to cover all its navigations, but it proved to be very difficult to do that within two jurisdictions. Accordingly, I understand that WI now intends to seek amendments to the bye-laws for the Republic, allowing it (inter alia) to increase the charges for various permits. However, the Canals Act 1986 allows WI to issue licences, and they are not subject to the restrictions in the bye-laws.

 

Royal water

The fragility of the water supply to the Royal Canal was shown in April, when Waterways Ireland closed the summit level of the canal because of low water levels; the 34th and 35th levels were also closed for emergency repairs. At time of writing, WI is hoping to be able to re-open the summit level on 1 June. Some boats that had intended to go west along the Royal to the Shannon were forced to go east instead, through Dublin and along the Grand Canal; happily, Effin Bridge, the lifting bridge at North Strand Road, worked properly this year.

The Royal always had fewer feeders than the Grand. The summit level was fed from Lough Owel, north of Mullingar, but while the canal was closed, Westmeath County Council found it needed more drinking water for the Mullingar area. In dry conditions, the Lough Owel feeder cannot meet both needs.

With great foresight, CIE (which then owned the canal) got the Council to agree that, if the canal was to be re-opened, it would provide an alternative supply.

Nowadays, environmental regulations mean that water abstraction needs more thought, more planning and more factors to be considered. Extensive studies were carried out and WI and the County Council agreed that the best possible alternative source was Lough Ennell, which is south of Mullingar: water could be pumped from there to the canal. The Council had to apply to An Bord Pleanála for permission; it has just completed oral hearings in Mullingar.

 

Traditional boats

In the first half of the nineteenth century, anyone travelling to the seaside resort of Kilkee could take the steamer to Kilrush and travel onward by road. But the passenger traffic was initially established by the turf boats of the Shannon Estuary: most of Limerick's fuel came from Poulnasherry, west of Kilrush, and was carried by small sailing boats, which also carried a few passengers.

A 24' replica of one of these boats was launched recently at Querrin, at the entrance to Poulnasherry. The Sally O'Keeffe was built by the Seol Sionna group http://seolsionna.org/, which grew out of the West Clare Currach Club. The boat will be used for sailing training. The Shannon Estuary, which is insufficiently appreciated, has a wealth of traditional boat types, but there were no extant Shannon hookers, so it is nice to see their return.

On the same weekend, another of those traditional boat types was featured in Limerick. The Ilen Wooden Boat Building School http://ilen.ie/gandelow-races/ had built five gandelows, boats used in the upper reaches of the estuary, and conducted races in the city.

And the Thomastown Regatta, on the Nore http://www.happyvalleyfestival.com/ebooklet.pdf, will feature traditional cots and racing boats: the 1905 racing cot Nore Lass, owned by the O'Farrell family, will be on display at the Grennan Mill Craft School.

 

Here are some updates I wrote about recently...

Water charges

The EU Commission sent a Reasoned Opinion to Ireland in November 2011, suggesting that Ireland had not correctly implemented the provisions of the Water Framework Directive that require "a cost recovery policy for water services that includes the environmental and resource costs of water use". The Commission believes that cost recovery should be extended to many other water uses, including hydroelectricity generation and the supply of water to navigations. Having got an extension of the deadline for replying, the Department of the Environment, Community and Local Government responded to the Commission. I asked for a copy of the response, but the department won't tell anybody what it's doing. I am appealing that decision, but without much hope.

 

Traffic

Waterways Ireland has kindly given me the Shannon traffic figures for the first four months of 2012. The numbers of movements in those months are always low, and can be significantly affected by the weather, so there can be quite a lot of variation between one year and another without its indicating any long-term trend. For example, back in 2002, there were 4875 boat movements in the first four months; the figure was up to 6204 in 2003 but back down to 5304 in 2004. It's important therefore not to read too much into the figures, but a five-year moving average suggests that traffic has been falling since 2007. The figure for 2012 was 4052. It will be interesting to see whether better weather balances economic gloom in the rest of the year.

 

Mineral Oil Tax

In the last issue, I gave the figures for the numbers of Mineral Oil Tax returns received by Revenue from owners of diesel-powered boats in the first two years of the scheme's operation. They told me that they got 38 returns in 2010 for the year 2009 and 41 in 2011 for 2010. I now have the figure for the following year, the returns made in 2012 for the year 2011. There was a very significant change, of 46%, but unfortunately it was downward, to 22. The Revenue Commissioners tell me that "[...] there were 22 returns received by 1 March 2012 for 2011, amounting to e53,398.58 MOT [Mineral Oil Tax] on 141,503.29 litres oil." That's an average of 6432.1 litres each, which is a lot, so I suspect that much of the total came from the hire fleet, with less than twenty private owners making returns.

 

Royal and Ulster Canals

I said, in the last issue, that I did not understand how the cost of the restoration of the Royal Canal, 146 km with 46 locks, could be less than the expected cost of the canal to Clones, 13 km with one double lock. It has been explained to me that the figure for the Royal was essentially only the marginal cost, recorded (initially) under Civil Service accounting procedures, so that it understates the total cost. It would be a huge job to try to find the full cost using modern accounting conventions, but unfortunately that means that we have no usable figure for the cost of the Royal, no basis for estimating the return on investment and no guideline on the value of any future restorations.

#InlandWaterways - Major renovations of Ringsend Basin at the city terminus of the Grand Canal have commenced, with Waterways Ireland advising all masters and users that works are expected to continue until mid May.

Diving operations commenced on 14 January last week. These involve strengthening the quay walls at Charlotte Quay, the replacement of a slipway and installation of stop planks at Camden Lock (Large Sea Lock).

All works will take place from pontoons adjacent to the area of works. Warning markers will be placed as required to advise all users of the basin.

As a result of the planned works, water levels in the basin may fluctuate. Owners and masters of vessels moored on both Charlotte and Hanover Quays are advised to tend their mooring lines as required.

Vessels may be required to move to facilitate works on Charlotte Quay. Advance notice will be given where possible.

Masters are requested to keep vessels clear of all works and comply with instructions from safety craft in the works areas.

#InlandWaterways - Two Waterford farmers have been successfully prosecuted by Inland Fisheries Ireland (IFI) over unauthorised in-stream works on the River Nier, a stretch of water important to salmon numbers in the south-east.

At a sitting of the District Court held at Clonmel on Tuesday 15 January, Oliver O'Gorman and Michael O'Gorman - of separate addresses in Ballymacarbry, Co Waterford - were convicted by Judge Terence Finn and ordered to pay fines and costs.

The prosecution followed investigations into discolouration and turbidity detected in the main channel of the River Nier on the evening of Saturday 24 March 2012. 

Patrick Kilfeather, senior fisheries environmental Officer with IFI, told Judge Finn it had been found that Oliver O'Gorman removed gravel from the Nier and used this in the construction of a roadway through his farm, while Michael O'Gorman had removed boulders and rocks from the river upstream to use in bank protection works on his farm. 

Additionally, the court was told that Michael O'Gorman had dug out the bed of a tributary of the Nier, and that the tributary in question was a very important salmon producing water.

In reply to questions put to him by Peter T Reilly, solicitor for IFI, Kilfeather told the court that had IFI been approached by the farmers concerned, advice and guidance would have been provided and it would have been possible to undertake certain works under IFI supervision during the period from July to September. 

Dolph McGrath, solicitor representing both defendants, entered a plea and submitted they were hard working young farmers who had learned an expensive lesson, and had not intentionally set out to cause environmental damage.

In passing judgement, Judge Finn noted that the works carried out had been ill-considered and ill-advised, adding that the defendants could have acquired the gravels and boulders they needed from a quarry as distinct from taking them from the river Nier. 

He commented it was a pity the defendants had not sought advice from IFI and noted from Kilfeather's evidence that such advice and guidance would have been readily provided. 

Michael O'Gorman was fined €1,000 and directed to pay legal costs of €671.75 and expenses of €760.97 to IFI. A second charge against him for works on the Nier tributary was marked proven and taken into account. Oliver O'Gorman was also fined €1,000 and directed to pay legal costs of €658.75 and expenses of €704.01.

Commenting on the circumstance of the prosecution, the regional director with Inland Fisheries Ireland said there is a general prohibition under the Fisheries Acts from interfering with river and stream habitat. In no circumstances is it permissible to remove materials from a river for use, as in this case, for construction purposes. 

He said that IFI was seeking the assistance and co-operation of farmers and landowners, as the primary custodians of the natural environment, not to engage in works likely to have effects on the fisheries and aquatic environment. In this regard he acknowledged the many farmers and landowners who had and continue to make contact with IFI to ensure that works which they require to undertake can be done in an environmentally sustainable manner.

#InlandWaterways - Waterways Ireland wishes to advise masters and owners on the Shannon Navigation that work will commence on the lock gates at Tarmonbarry Lock next Monday 14 January.

These works will be on-going for a period of approximately eight weeks until Thursday 14 March 2013. An alternative passage maybe accessed via the Camlin river loop upstream of Tarmonbarry Lock and the Clondra Canal downstream of the lock.

The cross-border body for Ireland's inland waterways also advises that the Carrick-on-Shannon Rowing Club's Head of River race will take place on Saturday 23 February from 9am till 5pm.

Masters of vessels are requested to proceed at slow speed and with minimum wash when passing this stretch of the navigation and to heed any advice or instructions issued by the regatta officials.

Meanwhile, Waterways Ireland has published a general marine notice reminding masters and owners of their responsibilities when navigating Ireland's rivers, lakes and canals.

The notice includes information on vessel registration, canal permits, public berthing, smart cards for service payments, speed restrictions, water safety and other important details for anyone boating in Ireland North and South.

#Angling - The Irish Times' angling correspondent Derek Evans welcomes the start of the salmon angling season tomorrow with a look at regulation changes for 2013.

Among them he notes that the number of open fisheries has risen to 55, while 59 rivers - five fewer than last year - will be closed, which marks some progress in Inland Fisheries Ireland's (IFI) efforts to ensure sustainability of Ireland's freshwater fish stocks.

Meanwhile, the catch and release programme has been modified to encompass the River Liffey from Islandbridge to Leixlip Dam for the first time, although at 32 the scheme includes two fewer rivers than last year.

"Catch and release will maintain, among other things, club membership interest and ensure a good footfall on the riverbank," writes Evans.

"Provided catch and release protocols are practised correctly, research has shown that the survival rate can be close to 100 per cent."

The Irish Times has more on the story HERE.

#INLAND WATERS - The European eel population is highly endangered and conservation of this species is a priority for Minister Fergus O’Dowd, who recently visited one of the ESB Trap and Transport sites in Athlone, Co Westmeath.

The minister saw first-hand the silver eel operation that involves the capture of the fish at strategic locations upstream in the Shannon catchment and their subsequent release downstream of Parteen Weir in order to aid their passage and bypass the hydropower generating facility.

Minister O’Dowd assisted the fishermen, Brian and Brendan Connell, in the weighing of the silver eels and loading them into an oxygenated tank for transportation by the ESB to Parteen.

“Eels are protected under EU directive,” said the minister. “I am satisfied that Ireland is addressing its obligations under the directive by ensuring the safe passage of eels past Parteen Weir as they travel onward to the Sargasso Sea to spawn.  

"I value highly the work done by ESB on the Trap and Transport initiative and the co-operation with IFI (Inland Fisheries Ireland). I saw at first hand how ESB, as a major commercial State company, continues to take very seriously its responsibilities in this area.”

The National and River Basin District Eel Management Plans specify actions that include closure of eel fisheries and markets, mitigation of adverse effects of hydropower generation facilities, improvement of water quality and bio-security issues.

The overall objective is to increase the biomass of spawning eel leaving Irish waters as the stock has depleted to a dangerous level.

Inland Fisheries Ireland monitors this ESB-sponsored operation throughout its duration, checking weigh and condition of the fish.

#ATLANTIC SALMON - About 39% of salmon mortalities were attributable to the impact of sea lice on wild salmon fisheries, according to a new international study.

The research, published in Proceedings of the Royal Society B, involved experts from Inland Fisheries Ireland collaborating with the Scottish Oceans Institute at the University of St Andrews, the Department of Zoology at the University of Otago in New Zealand, the Atlantic Veterinary College at the University of Prince Edward Island in Canada and the Institute of Marine Research in Norway.

In a statement on the report, IFI says: "In previously published studies, groups of salmon smolts were treated to protect them against sea lice infestation and other groups were untreated and both groups released to sea into 10 areas of Ireland and Norway. A proportion of these released fish were recaptured as adult salmon one or more years later.

"Analysis of the results of all previously published studies together provide experimental evidence from a large marine ecosystem that sea lice can have large impacts on salmon recruitment, fisheries, and conservation. The sea lice were likely acquired during early marine migration in areas with salmon farming, which elevate local abundances of sea lice."


IFI says the results "indicate that parasite-associated mortality may cause the closure of some fisheries when conservation targets of return adult abundances are not being met. However, the implications of these results may be most serious for small populations in small river systems."

The inland fisheries body explains that the high natural mortality rate of both treated and untreated salmon groups was accounted for, which revealed "a large effect of parasites".

"Precisely because natural mortality rates are high, even a proportionally small additive mortality from parasites can amount to a large loss in adult salmon recruitment," it adds.

Minister of State for Natural Resources Fergus O'Dowd welcomed the report, stating:  “From the results of this detailed study, it is crucial that sea lice levels are maintained below [designated] protocol levels, particularly in spring when wild salmon smolts are migrating to sea to avoid increased marine mortality.

Minister O'Dowd added that the results of this study "augment our knowledge in the context of proposals for aquaculture development".

The news comes in the wake of IFI's dispute with Bord Iascaigh Mhara over the exclusion of a report critical of the proposed new deep sea wild salmon farm in Galway Bay from the statutory consultation.

The scheme has faced opposition from local salmon anglers who fear the new facility would pose a threat to wild salmon stocks in Irish rivers by increasing the risk of sea lice infection.

#INLAND WATERWAYS - Anyone with boats afloat on Ireland's inland waterways have been advised to check with their insurers before mooring their vessels for the winter.

Stuart McNamara of Powerboat.ie comments on the website's forum regarding his own cautionary tale while searching for a winter mooring spot for his Freeman 27, which is normally used as a training boat by Hodson Bay Watersports Athlone.

"Luckily, I checked with my insurers before I moved across the lake," he writes. "It appears that they no longer insure winter moorings unless they are at supervised marinas or floating jetties at public harbours.

"The reasoning behind this was explained to me as being the greatly increased risk from unattended mooring lines in rising water levels. I have seen many boats sinking alongside Hodson Bay Pier in recent years because of this, so the insurer's position does make sense and is understandable."

He adds: "The lesson to be learnt is to check your marine insurance if just tied alongside somewhere unattended for the winter!"

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.
