Building on the success of pilot programmes in 2019 and 2020, the Tuna CHART (CatcH And Release Tagging) fishery to collect scientific data on bluefin tuna will return in 2021, subject to COVID-19 restrictions.

Tuna CHART is a collaborative scientific programme between Inland Fisheries Ireland and the Marine Institute in partnership with the Sea Fisheries Protection Authority, the Department of Agriculture, Food and the Marine (DAFM) and the Department of Environment, Climate and Communications (DECC).

In 2020, the Tuna CHART programme authorised 22 charter skippers to operate a scientific fishery — in which anglers participated fully — to catch, tag and release bluefin tuna. These professional skippers were trained to tag, measure and record bluefin data.

Despite the limitations of the pandemic, 685 bluefin tuna were caught, tagged and released around the Irish coast — a 230% increase in bluefin tagged on the previous year.

The most productive sites were the North-West and the South coast, mainly the waters of the Cork coastline. As many as 11 bluefin were tagged on one angling trip, a new Irish record. The largest tuna tagged was 275cm, weighing an estimated 822lbs.

All tuna were carefully handled subject to strict guidelines set by the Tuna CHART programme and all were released alive. Data from the tagging programme has been collated by the partnership for reporting to the International Commission for the Conservation of Atlantic Tuna (ICCAT).

This year a maximum of 25 authorisations may be granted to qualifying vessels and skippers around the Irish coast for fishing between 1 July and 12 November. Applications are now open and will be accepted until 1pm on Friday 9 April.

Depending on the successful operation and review of this year’s fishery, it is intended that a scientific catch-and-release fishery may also operate in 2022.

The partnership says a core aspect of the Tuna CHART programme is the welfare and successful release of the bluefin tuna. Authorised skippers will be required to have high specification rods, reels and line in advance of the open season in order to ensure that the fish is brought alongside the vessel to be measured and tagged in the water in a timely manner.

Data collection for scientific assessment is the primary purpose of the fishery and will continue to be a key requirement for skipper participation in this scientific catch-and-release fishery, the partnership adds.

Skippers will be required to collect data on every bluefin trip undertaken and each bluefin tuna they catch, tag and release, and their angling and data recording expertise is an important part of the overall survey programme.

Anglers will have an opportunity to participate in this fishery and contribute to this important scientific study by chartering and fishing from authorised vessels only. Unauthorised vessels are not permitted to target or catch bluefin tuna, and any unauthorised person found to be targeting bluefin tuna will be prosecuted. Applications for authorisations are open to charter skippers only.

Twenty-two charter angling vessels have been granted authorisation to participate in a bluefin tuna data collection programme after a successful pilot last year.

The Tuna CHART (CatcH And Release Tagging) programme will see skippers catch, tag, measure and release Atlantic bluefin tuna for data collection purposes off the Irish coast.

The authorised vessels, which are located in Cork, Clare, Galway, Sligo and Donegal, will support an international scientific programme to increase knowledge of the behaviour and abundance of bluefin tuna in Irish waters and across its distribution generally.

Atlantic bluefin tuna, the largest tuna in the world, frequent Irish coastal waters to feed during the species’ annual migration through North Atlantic waters.

The bluefin tuna is prized by sea anglers for its power and fighting ability and is a very valuable commercial species, though there is currently no sport or commercial fishery for bluefin tuna in Ireland.

The new programme, which has been developed by Inland Fisheries Ireland and the Marine Institute in partnership with the Sea Fisheries Protection Authority and the former Departments of Agriculture, Food and the Marine, and Communications, Climate Action and Environment, will operate again in 2020 having commenced on a pilot basis in 2019.

Eamon Ryan TD, minister with responsibility for inland fisheries, said: “The 22 angling vessels authorised by my department, increased from 15 last year, will contribute substantially to essential bluefin tuna data collection as they migrate along the Irish coastline.

“The recreational fisheries sector is crucial in the delivery of this research programme and we look forward to continue working with all the State agencies involved.

“I want to acknowledge the key role of the authorised charter skippers and their crews who are bringing their unique expertise to bear on providing valuable data for scientific purposes, and the ‘citizen scientist’ anglers who will catch the fish. The fact that 209 fish were tagged last year with no mortalities is a great achievement by the skippers.”

The Sea Fisheries Protection Authority and Inland Fisheries Ireland will undertake inspections and patrols around the coast to ensure this remains a strictly controlled programme.

Building on the success of last year’s Tuna CHART (CatcH And Release Tagging) pilot programme, a bluefin tuna research catch-and-release fishery for Ireland will operate in 2020.

A maximum of 25 authorisations may be granted to qualifying angling charter vessel skippers around the Irish coast for this fishery which will open on Wednesday 1 July and close on Thursday 12 November, without exception.

And depending on the successful operation and review of this year’s fishery, it is intended that a scientific catch and release fishery may also operate in 2021 and 2022.

Atlantic bluefin tuna, the largest tuna in the world, frequent Irish coastal waters to feed during its annual migration through North Atlantic waters. The bluefin tuna is prized by sea anglers for its power and fighting ability and is a very valuable commercial species.

The Tuna CHART programme is a collaborative scientific programme between Inland Fisheries Ireland (IFI) and the Marine Institute in partnership with the Sea Fisheries Protection Authority, the Department of Agriculture, Food and the Marine (DAFM) and the Department of Communications, Climate Action and Environment (DCCAE).

In 2019, the Tuna CHART pilot programme authorised 15 charter skippers to operate a scientific fishery, in which anglers participated fully, to catch, tag and release bluefin tuna.

These professional skippers were trained to tag, measure and record bluefin data and over the course of the 2019 three month season, 219 bluefin tuna were caught, tagged and released. As many as eight bluefin were tagged on one fishing trip.

All tuna were carefully handled subject to strict guidelines set by the Tuna CHART programme and all were released alive. Data from the tagging programme are being collated by the partnership for reporting to the International Commission for the Conservation of Atlantic Tuna (ICCAT).

As with the pilot programme, this year’s authorised skippers will be required to have high specification rods, reels and line in advance of the open season in order to bring the fish alongside in a timely manner. Skippers will be required to collect data on every bluefin trip undertaken and each bluefin tuna they catch, tag and release.

A call for applications for the 2020 fishing season will be announced next Tuesday 18 February and the last date for the receipt of a completed application will be 1pm on Friday 6 March.

While there is no sport or commercial fishery for Bluefin tuna in Ireland, a pilot Bluefin Tuna Data Collection Programme has been developed by Inland Fisheries Ireland (IFI) and the Marine Institute (MI) in partnership with the Sea Fisheries Protection Authority (SFPA) the Department of Agriculture, Food and the Marine (DAFM) and the Department for Communications, Climate Action and Environment (DCCAE) . This programme, comprising 15 authorised charter angling skippers, commenced on the 15th of August in order to catch, tag and release Atlantic bluefin tuna for data collection purposes off the Irish coast and is part of the International Convention on the Conservation of Atlantic Tuna (ICCAT) research programme which is supported by the EU Commission.

These authorised skippers with vessels operating out of ports located in Cork, Clare, Galway, Sligo and Donegal are supporting scientific work to increase knowledge of the behaviour and abundance of Bluefin tuna in Irish waters. All authorised skippers have participated in training with guidance provided around fish handling, welfare, tagging and data recording. Participants in the programme catch, tag and release Bluefin tuna while adhering to strict fish safety and handling procedures at all times.

Authorisations were originally granted to the 15 charter skippers from mid-August until mid-October. This pilot project has been very successful with 201 fish tagged and released to date with utmost consideration to their welfare. Due to the migratory patterns of Bluefin tuna, there has been little activity in the South and South West. As a result, the fishing season will now be extended for a further four weeks until the 12th of November to seek data which will help improve our knowledge of the population structure and distribution of Bluefin tuna in these regions. There will be no further extensions as lower water temperatures could hinder post-release survival of these fish after mid-November. 

Minister Creed said today: “I am delighted by the excellent cooperation shown between my Department, DCCAE, SFPA, MI and the IFI in the development and management of this pilot project. The extension of the programme will provide an opportunity to gather further data and improve our understanding of the migratory patterns of Bluefin Tuna around our coasts.”

Minister Canney said: “I fully support the continued involvement of my Department and Inland Fisheries Ireland in the collaborative pilot project to collect valuable data on Bluefin tuna in Irish coastal waters. The partnership approach has led to a very successful round of data gathering with some 200 fish tagged and recorded since the pilot programme opened.

“The extension of the programme for a further four weeks will provide an excellent opportunity to encourage the collaborative effort and most importantly provide a research dividend by increasing the data collected. I have approved the issuing of renewed authorisations by my Department for the sea angling vessels participating in the initiative to continue until the 12th of November” he added.

The Sea Fisheries Protection Authority and Inland Fisheries Ireland will undertake inspections and patrols around the coast to ensure this remains a strictly controlled fishery. Anglers wishing to engage in this fishery must only do so on a sea angling vessel specifically authorised to participate in the pilot programme. Any person engaging in this fishery on any vessel which is not appropriately authorised will be in breach of the Sea-Fisheries and Maritime Jurisdiction (Bluefin Tuna) Regulations 2019 (S.I. No. 265 of 2019).

Fifteen angling vessels will soon be granted authorisation to participate in Tuna CHART (Catch and Release Tagging), a pilot Bluefin Tuna Data Collection Programme.

As previously reported for Afloat.ie by Lorna Siggins, the programme will see the 15 authorised vessels catch, tag and release Atlantic bluefin tuna for data collection purposes off the Irish coast.

These vessels, which are located in Cork, Clare, Galway, Sligo and Donegal, will support scientific work to increase knowledge of the behaviour and abundance of bluefin tuna in Irish waters — which currently do not host a sport or commercial fishery for the species.

The new programme, which has been developed by Inland Fisheries Ireland (IFI) and the Marine Institute in partnership with the Sea Fisheries Protection Authority (SFPA), the Department of Agriculture, Food and the Marine and the Department for Communications, Climate Action and Environment (DCCAE), will operate on a pilot basis this year.

Authorisations will be granted from mid-August until mid-October, and all skippers and trained crew have participated in training with guidance provided around fish handling, welfare, tagging and data recording.

Participants in the programme will catch, tag and release bluefin tuna while adhering to strict fish safety and handling procedures at all times.

Marine Minister Michael Creed has welcomed the initiative. “My department has been working on this project for two years at both EU and domestic levels and I am happy to announce the commencement of the project this month,” he said.

“This initiative will allow the Marine Institute and Inland Fisheries Ireland to collect valuable data on the migratory patterns of bluefin tuna in Irish waters in a tightly controlled environment.

“This project has been a wonderful example of co-operation between my department, DCCAE, SFPA, IFI and the Marine Institute and I am looking forward to the continued development of this relationship.”

Sean Canney, Minister with responsibility for inland fisheries, added: “The angling vessels which will be receiving authorisation from my department will contribute in a very tangible way to important data collection around Bluefin tuna as they migrate past the Irish coastline.

“The recreational fisheries sector is crucial in the delivery of this pilot programme and we look forward to working with all the State agencies involved and critically with the skippers and their crews who have received authorisations in providing valuable data for scientific purposes.”

The SFPA and IFI will undertake inspections and patrols around the coast to ensure this remains a strictly controlled fishery.

Anglers wishing to engage in this fishery must only do so on a sea angling vessel specifically authorised to participate in the pilot programme. Any person engaging in this fishery on any vessel which is not appropriately authorised will be in breach of the Sea-Fisheries and Maritime Jurisdiction (Bluefin Tuna) Regulations 2019 (SI No 265 of 2019).

The rapid swimming migratory Atlantic bluefin tuna may be targeted by a limited number of Irish recreational craft under a pilot scientific research programme run by several State agencies writes Lorna Siggins.

Inland Fisheries Ireland (IFI) and the Marine Institute are seeking expressions of interest from up to 15 sea angling vessels, which would be authorised to run a catch, tag and release programme to collect data on the movements of the fish for the first time.

Atlantic bluefin tuna is the largest tuna and takes in the Irish coastline on its migratory track between the Mediterranean and the central Atlantic. It can reach a weight of over 600 kg, and over three metres in length, and can live for over 30 years.

Under International Commission for the Conservation of Atlantic Tunas (ICCAT) rules, Ireland could not allow targeted angling of bluefin tuna for data collection.

Last year, a European Commission audit had criticised the State for a “complete lack of control” over the illegal capture of bluefin tuna by sea anglers off the west coast.

It cited IFI evidence that a “targeted” recreational fishery for bluefin tuna had developed along the west coast of Ireland, with “numerous chartering companies advertising trips for tourists over the internet”.

The audit said there was evidence that some catch was being kept, landed and offered for sale in breach of regulations, given that Ireland had no quota.

However, IFI says that changes secured by Ireland at an ICCAT annual meeting last year will allow limited targeting of the species by recreational anglers, but for scientific purposes only.

The new pilot programme is being developed in partnership with the Sea Fisheries Protection Authority (SFPA), the Department of Agriculture, Food and Marine and Department of Communications, Climate Action and Environment.

Minister for Marine Michael Creed said he warmly welcomed the new pilot programme which would “build on and complement the extensive scientific work undertaken in recent years by the Marine Institute” and “increase our knowledge of the behaviour and abundance of bluefin tuna in the waters off the Irish coast”.

Applicants for the new data collection pilot programme will be assessed on the basis of previous experience in undertaking “collaborative research and scientific work”, and must have a minimum of five years’ experience of sea angling in Irish waters.

Applicants must also have experience in targeting large pelagic fish, and be equipped for same, and be willing to operate under specific authorisation controls, IFI says.

Authorisations will be valid from mid-August until mid-October of this year, IFI says, and strict fish safety and handling procedures will have to be followed at all times.

Training will be required in fish handling, welfare, tagging and data recording, and all vessels will be monitored by fisheries observers, IFI says.

Both IFI and the SFPA will “undertake inspections and patrols around the coast”, it says, and “any unauthorised skippers found targeting bluefin tuna will be prosecuted”.

It says anglers may participate in the fishery by booking places on an authorised vessel, and full details of the programme are on.

Minister for Agriculture, Food and the Marine, Michael Creed T.D., today announced that he has secured approval at EU and international level for the introduction of a science-based catch, tag and release fishery for Bluefin tuna for Irish recreational anglers. This scheme will complement the work on satellite tagging of bluefin tuna that is being undertaken by the Marine Institute.

Minister Creed said that “As part of the negotiations on the new international management plan for bluefin tuna in the east Atlantic, Ireland was able to secure an agreement that will allow countries like Ireland, that do not have a commercial Bluefin tuna quota, to operate a catch-tag-release fishery for gathering scientific data.” This new management plan was adopted at the 2018 International Commission for the Conservation of Atlantic Tunas (ICCAT) Annual Meeting. 

Minister Creed continued “My Department is currently working with the Marine Institute and the Sea Fisheries Protection Authority on a pilot project that will allow up to 15 angling vessels with trained tagging operators to target bluefin tuna in 2019. This aim of the project is to build on work undertake to date and to increase our knowledge of the behaviour and abundance of BFT in the waters off the Irish coast. It will also provide an ancillary benefit in that it will support angling tourism in peripheral coastal communities, including in particular Donegal.”

Previously, under ICCAT rules, Ireland could not allow targeted angling for bluefin tuna as we do not have a bluefin tuna quota. The changes secured by Ireland will now allow targeting for tagging purposes only by recreational anglers. 

Minister Creed added “Our fishing industry has expressed concerns about the increasing numbers of Bluefin tuna in the Irish 200 miles zone and this programme will allow us to understand more about blue fin tuna - their habitat, migration patterns and concentration in waters around Ireland.”

The exact details of the pilot scheme will be developed over the coming period in consultation with the Department of Communications, Climate Action and Environment which is responsible for angling.

#Bluefin- A Donegal TD's push for a bluefin tuna quota for local game anglers has prompted a meeting between Marine Minister Simon Coveney and the EU Fisheries Commissioner.

According to Donegal Now, Thomas Pringle TD has welcomed the move to request a three-tonne quota for bluefin "despite the fact that I’ve brought this proposal before the Dáil on a number of occasions over the past year".

As previously reported on Afloat.ie, Inland Fisheries Ireland said that any initiative to develop a catch-and-release fishery for bluefin in Irish waters would demand struct protocols and reporting to the International Commission for the Conservation of Atlantic Tunas (ICCAT).

But the independent Dáil deputy says recreational angling for bluefin tuna "could bring huge potential for Donegal in terms of job creation and boosting tourism in the region".

Donegal Now has more on the story HERE.

#bluefintuna – Sea anglers and charter boat skippers are reminded that the Bluefin Tuna recreational fishery remains closed in 2014. Inland Fisheries Ireland (IFI) and the Sea-Fisheries Protection Authority (SFPA) have released updated information in relation to the recreational catches of Bluefin tuna in Ireland. European fisheries regulations governing the catching, landing and sale of Bluefin tuna direct states that unless a Member State has specifically assigned a portion of their annual national quota to sports and recreational fisheries to target these fish no such fishing can take place.
Current Bluefin Tuna fisheries management regulations (EU Reg 302/2009 and International Commission for the Conservation of Atlantic Tunas( ICCAT) Recommendation 12-03) stipulate that recreational and sport fisheries may be facilitated by Member States by allocating a specific national Blue Fin Tuna quota to the sectors, but because Ireland does not have a quota the EU has advised that a specific recreational fishery cannot be operated.
Dr Ciaran Byrne, CEO of IFI said: "IFI is supportive of hard-pressed coastal communities and the marine sector in particular and are aware of the economic boost which recreational angling can bring to such peripheral communities. In this regard, IFI continues to actively investigate the possibility of operating a recreational bluefin tuna catch and release fishery."
Any initiative by IFI to develop a catch and release fishery for recreational fishers in Irish waters will demand strict catch-and release protocols with obligatory catch logging and reporting to the International Commission for the Conservation of Atlantic Tunas (ICCAT). Such a proposal from Ireland will need the input and support of Ireland's regulatory maritime agencies to prepare a submission for consideration by the Scientific Committee ICCAT and the European Commission.
In the meantime, any Bluefin Tuna mortalities arising from fish accidentally caught in the course of angling must be notified to SFPA who are charged with the enforcement of the above regulations. The fish will be confiscated and disposed of.
Susan Steele, Chair of the SFPA said: "Ireland does not have a direct fishery for Bluefin Tuna in Ireland. Ireland does have a 1% by catch of Bluefin Tuna as part of the Northern Albacore fishery. The vessels that partake in the Northern Albacore fishery must obtain a specific fishing authorisation from the Department of Agriculture, Food & Marine. For anyone engaged in sports or recreational sea angling this means that if a Bluefin Tuna is caught while sea angling it has to be immediately released as the fish cannot be targeted or landed by an Irish boat."

#Angling - Inland Fisheries Ireland (IFI) has urged marine sport anglers to put conservation first when it comes to the endangered bluefin tuna - particularly those in the tuna hotspot of Donegal Bay.

In a statement, the national fisheries body said: "For a long time, Ireland has been recognised for its marine sport fishing. The vast variety and quality of our angling has given the country a reputation of which we are justly proud."

Bluefin tuna catches by the commercial fishing fleet targeting other species were first reported in the 1980s, and such reports became quite common on the west coast by the mid 1990s, though no fish fell to rod and line until 2000. 

The following year, a new Irish and European record was set by Adrian Mulloy, fishing with skipper Michael Callaghan. On the 5 October 2001 Adrian caught a fish of 968lbs near Rathlin O’Beirne Island.

In 2002 and 2003, more bluefin tuna were caught and one boat contributed to the 'Tag a Giant' programme run by Stanford University and supported in Ireland by Bord Iascaigh Mhara (BIM).

"While these were heady days for big game fishing in Ireland, it all happened against the backdrop of a global decline in a species that is now famously threatened by overfishing," said IFI.

In 2012, European regulations governing the harvesting of bluefin tuna were changed as the species became even more endangered. 

Ireland does not have a bluefin tuna quota, and for this reason "no allocation is available for sports or recreational fishing," said the IFI statement. "Furthermore, there is no facility in Irish fisheries regulations to permit angler-caught bluefin tuna to be landed into any Irish port, and there is no provision for the sale of these fish. 

"While IFI would love to see the development of a sustainable fishery for this wonderful species, given the continued significant decline of the species and the fragile nature of the stock, the key imperative has to be one of conservation."

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.
