#Fishing - The Marine Institute is inviting tenders for the supply of a commercial fishing vessel to conduct a boarfish acoustic survey in ICES divisions VII b, c, g, h, j & k (west of Ireland, Celtic Sea and northern Biscay).

The vessel would be chartered for a period of 21 days to survey spawning aggregations of boarfish – a big seller for Ireland in the Chinese market – using hydro-acoustic techniques.

Vessels are invited to tender on the basis of their ability to undertake the survey schedule. This comprises following a pre-determined cruise track in the order of 3,200 nautical miles carried out over 21 days with 20hr operations (4am-midnight) and with directed trawl stations on fish schools of interest as and when required.

A single pelagic midwater trawl with a vertical opening of greater than 40m and contain a 20mm codend liner and/or sprat brailer will be a requirement for the survey. A liner can be provided if required but all other associated fishing equipment must be provided by the vessel.

The survey will be timed to coincide with the southerly end point of the RV Celtic Explorer on 10 July 2015 and this survey will act as a continuation. It is therefore essential that the charter vessel is out on the water and ready to begin surveying no later than midnight on 9 July 2015.

Detailed information of the track and survey plan will be provided by the Marine Institute. The successful applicant will be selected based on technical suitability, cost of charter, pelagic fishing track record and previous experience in scientific research and surveys.

The closing date for tenders is this Friday 29 May 2015 at 12 noon. Full details of the tender are available in a PDF to read or download HERE.

#SwanCensus - Only a handful of Bewick's swans have been recorded in Ireland this winter ahead of a major international survey of migratory swans this weekend.

As RTÉ News reports, just three of the visiting waterfowl species have been sighted in Wexford so far, amid concerns that climate change is seeing them stay put in their Siberian homeland.

Whooper swans will also be counted in the latest edition of the five-yearly survey across a thousand coastal and waterside sites in Ireland this weekend, to see how numbers stand now against the 15,000 birds recorded in 2010 - half of the entire breeding population in their Icelandic home.

#MarineScience - The first underwater TV (UWTV) survey of the Bay of Biscay Nephrops grounds was carried out on the RV Celtic Voyager from 20-29 September.

This survey involved collaboration between the fishing industry and IFREMER, the French equivalent of the Marine Institute. The Celtic Voyager was chartered for this survey by the French fishing industry (CNPMEM).

The team of French scientists from Lorient were trained in the UWTV survey methodology by Jennifer Doyle, an expert from the Marine Institute. A fishing industry observer also participated in the survey.

This was the furthest south that the Irish Celtic Voyager research vessel has been to at 45°55′N 2°22′W.


The Bay of Biscay Nephrops grounds, known locally as 'la Grande Vasière', have an area of approximately 11,600 sqkm and support landings of Neprophs (better known as Dublin Bay prawns or langoustines) of around 4,000 tonnes annually.

During the 10-day survey, 160 UWTV stations were successfully completed with an average depth of 100 metres. At each station a sled-mounted camera system is towed at 1 knot. This allows for the detailed examination of the sea bed. The Nephrops burrows on the video footage collected are identified and counted by trained and experienced scientists.

Weather conditions throughout were perfect for TV operations with light winds, little or no swell and sea surface temperature around 20 degrees C. The visibility at the seabed was also excellent. The results from this survey will be analysed by IFREMER scientists to determine stock abundance.

The Marine Institute have been developing UWTV survey methods and technology since 2002. Since then, survey coverage has been expanded: in 2014 the main Nephrops stocks fished in Irish waters are have all been fully surveyed – Aran Grounds, Porcupine Bank, Western Irish Sea, Eastern Irish Sea, South Coast, Smalls, Labadie, Jones and Cockburn Banks.

These UWTV surveys form the cornerstone of the ICES assessments and management advice. The results of the TV surveys directly form the basis of the catch options.

All UWTV Marine Institute surveys reports are available online in the Marine Institute's open access repository.

#CoastalNotes - The new Foreshore Bill is set to "radically change" Ireland's relationship with our coast, according to Coastwatch Ireland co-ordinator Karin Dubsky.

As The Irish Times reports, Dubsky was speaking at the launch of the 2014 Coastwatch Survey, welcoming the new bill that will see responsibilities for coastal management transferred to local authorities.

Previously, the Foreshore and Dumping at Sea (Amendment) Bill 2009 had transferred all foreshore licensing functions not associated with aquaculture and sea fishing from the then Department of Agriculture, Fisheries and Food to the erstwhile Department of the Environment, Heritage and Local Government.

Dubsky said the new legislation would give ordinary citizens a chance to shape Ireland's coastal policy via public audits such as the annual month-long Coastwatch Survey.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport advises that Osiris Projects will be carrying out two survey operations along the proposed interconnector route between Ireland and France.

The surveys will extend from the Shoreline at two locations in Co Cork (Ballinwilling Strand main route and Ballycroneen Beach alternative route) across the Celtic Sea to the shoreline at two locations in Northern France (Roscoff main route and Pontusval alternative route).

The first survey operation started on 17 August and is expected to run until 30 September, weather permitting. Survey works will be undertaken on the survey vessel RRS Ernest Shackleton (Callsign ZDLSI).

The vessel will operate on a 24-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The RRS Ernest Shackleton will be towing survey equipment below the surface up to 600m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The second survey operation was expected to start on the Irish side yesterday (10 September) and will run until 20 September, weather permitting. Survey works will be undertaken on the survey vessel MV Proteus (Callsign 2HBL7).

The vessel will operate on a 12-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The corridor width for each landing will be 250 metres from the high water mark to the 10-metre contour, then the corridor will widen to 500 metres as the route moves to France.

The survey vessel may be found running both along the corridor and in the general vicinity of the survey corridor. The vessel will be working between high water and 20 metre contour and in daylight hours only.

The MV Proteus will be towing survey equipment on and below the water surface up to 300m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

Both vessels will be listening on VHF Channel 16 throughout the works. Full details of co-ordinates of the work areas are included in Marine Notice No 55 of 2014, a PDF of which is available to read or download HERE.

Meanwhile, a hydrographic and geophysical survey operation is presently being undertaken by INFOMAR on the RV Celtic Voyager off the southwest coast of Ireland, continuing till 17 September.

The vessel is towing a magnetometer sensor with a single cable of up to 100m in length. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The vessel will display appropriate lights and markers, and will be listening on VHF Channel 16 throughout the project.

Co-ordinates for the bounding box of the survey area are detailed in Marine Notice No 54 of 2014, a PDF of which is available to read or download HERE.

#Angling - Inland Fisheries Ireland (IFI) wants your help to improve fish habitats and make your angling experience better.

Anglers across Ireland are being invited to take part in a survey as part of an international report on anglers' habits and how they rate the fisheries they frequent.

"Great fishing is about the prospect of lots of quality fish while spending time enjoying the outdoors," says IFI. "Quality fish come from healthy populations enjoying good water, plenty of food and access to habitat.

"When we have dams, denuded riverbanks, culverts, dredged gravel beds and poor water quality we don’t have healthy fish and we certainly don’t have great fishing experiences."

The survey should take no more than five minutes to complete. All information collected is anonymous and not related to your email address.

IFI is also offering a prize draw liked at the end of the survey where you could win a €300 tackle voucher.

#Angling - Inland Fisheries Ireland (IFI) is currently carrying out a complete fish stock survey on Lough Ree in the Midlands to assess the current status of coarse, pike and game fish populations in the lake.

The survey, which began on Monday 24 February and continues till Friday 14 March 2014, involves netting of 200 sites throughout Lough Ree performed by IFI staff from the Shannon River Basin Districts (ShRBD) and research staff in Swords, and comprising a total of five boat crews, two safety crews and processing crews based around Lough Ree.

The time of year of the survey is comparable with netting surveys on other major lakes in Ireland over the last 30 years or so. The type of information gleaned from the survey will include catch per unit effort (CPUE) for each fish species, size distributions of fish caught, aging for all species and microsatellite (DNA) analysis (for brown trout).

Sampling to assess the distribution of introduced (invasive) species will be carried out, with particular reference to the invasive ‘Asian clam’ Corbicula fluminea.

The genetic analysis of the brown trout will contribute the survey work carried out in 2013, with participation from anglers on Lough Ree, Lough Derravaragh, Lough Owel and the River Suck. In 2013 anglers sampled scales from adult trout caught in these areas and submitted these samples to IFI for DNA analysis.

In addition, all the major sub-catchments around Lough Ree, River Inny and River Suck were electro-fished in 2013 to help build up a baseline by which adult trout caught in these waterways can be attributed to the rivers in which they were spawned.

IFI describes this as very exciting work that will help build up a picture of what rivers (or parts of river sub-catchments) are contributing to the adult brown trout populations on these major lakes.

Similar work on the major western lakes have shown that the native brown trout can undertake extensive feeding and spawning migrations and has also shown (for example the ‘Croneen’ trout of the Camcor/Little Brosna system) that there are genetically distinct populations of trout which undergo large migrations from specific river systems to feed in large lakes like Lough Derg and Lough Ree.

Another aspect of this current netting survey will involve floy tagging of pike. Floy tags will be inserted below the dorsal fin of the pike and each fish will be released. Each tag will have a unique reference number which can easily be identified on later recapture of the pike.

Anglers will again be asked to record these tag numbers and potentially the length of fish, particularly during the major pike angling tournaments on Lough Ree in 2014. This will work as a mark-recapture method for estimating pike numbers in the lake, and it could potentially provide information on the growth rate of pike.

The survey crews will be very visible on Lough Ree over the next few weeks and all sets of nets will be marked with distinctive buoys labeled ‘IFI Survey’. Any anglers or other lake users are asked to be vigilant if out and about on the lake over the next few weeks and to avoid snagging in the nets.

#Angling - Almost one in every 10 people in Northern Ireland went fishing in the last 12 months - but 70% of NI residents said they had no interest in the sport.

These statistics were among the key findings in a new report on attitudes to angling by adults in Northern Ireland, using data from the Northern Ireland Omnibus Survey conducted this past April.

As the Belfast Telegraph reports, among the other findings were that almost a fifth of the population used to go fishing but no longer so do, while some 4% of the populace have never fished before and would like to try.

Most respondents cited their lack of interest in putting them off angling as a pastime, while 19% said they did not have enough free time.

But 12% said better information on how to fish would encourage them to take out a rod and reel.

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.
