Fishing – THE MAN WHO SEARCHED FOR 60-FOOTERS

#islandnation – Can you imagine spending years searching for old 60-foot boats, travelling the country's coastline because of a 'bug' within your system?

Pat Nolan from Cork, who now lives in County Antrim, has done that, "a labour of love, meeting with many wonderful people" who sailed these iconic vessels.

Six years ago he began tracing the histories of all eighty-eight 50-foot fishing boats built by the State fisheries board, Bord Iascaigh Mhara between 1949 and 1970, a mammoth task which he completed in two years and published in a book called 'Sea Change'. Now he has six books about fishing boats to his credit, the latest called 'A Step Up' and which, logically enough perhaps, is a record of the BIM 56-footers which were regarded as a 'step up' when introduced to Irish waters for commercial fishing.

Understandably, Pat comes from a family steeped in commercial fishing activities, into which he was born in Baltimore in West Cork. A science graduate of University College, Cork, he worked in Nigeria for a number of years before returning to Ireland and settling in Ballycastle.

He has compiled individually-traced histories of all 39 BIM-built 56-footers, a huge contribution to the archive of Ireland's maritime history. Built at several boatyards around the coast, their construction provided great employment and underwrote the shipwright tradition in Ireland which has now, unfortunately, declined to the great loss of the marine industry. Tyrrells of Arklow designed their own 56-footers for BIM.

"That all 56-footers were not identical is beyond dispute, differences existed in detail, layout and even design, but the boats were readily recognisable, regardless of variations," says Pat. "All of the boats were well-built, efficient and regarded as 'small big boats' and first-class weather boats. Yet I'd have to say there are divided opinions as to how well they met the requirements of their era, even though they were iconic boats."

Safety – ALONE ON THE WATER

My report last week that the Coast Guard had tried to get the Marine Casualty Investigation Board to make a strong recommendation against going out on the water alone drew quite a reaction from readers, varying from "nannyism" to "why can't there be mandatory licences for boating."

"What does the Coast Guard know about single-handed sailing or good seamanship for that matter? It's the same as the priests giving marriage guidance courses," Emailed Gerry Burns.

Trudy McIntyre commented: "For driving a car you need a licence and mandatory driving classes, before you go at it alone!! Why can't there be the same for pleasure boating?"

Rory described the call as: "More dictatorship and nannyism!" while Tony O'Leary wrote that "the RNLI and Coast Guard are volunteers who at the end of the day are only trying to help people when they are in trouble. In most Lifeboat and Coast Guard crews there are people who have a vast amount of experience at sea" and Jerome Lordan wrote: "Lifeboat crews and Coastguards today do not for the most part have long-time experience at sea like they had in the past when these units were manned by experienced fishermen and ex-seafarers. They seem to think you can just train up and that is sufficient. You cannot buy or train long-time experience at sea!"

Obviously a topic that raises very different opinions, amongst which are the kayakers, canoeists and solo-rowers who told me that they venture out alone as part of their sport. It should be remembered also that Irish solo sailors have achieved success in racing internationally, such as Barry Hurley from Cobh and a member of the Royal Irish YC in Dun Laoghaire with his boat Dinah.

Shipping – IRAN'S FIRST TANKER

Having shown off its first, though somewhat unusual-looking submarine to the maritime world, as I reported a few months ago, Iran has now introduced the first oil tanker it has built. Iran Shipbuilding and Offshore Industries Complex Co. (ISOICO), manufactured the ship which is 178 metres long, 32 metres wide and has a 9-metre draft according to ISOICO. Operated by the National Iranian Tanker Company, it is reported to have cost US$30m. and to be capable of carrying 35,000 tons of oil products. Its maiden voyage has been undertaken in Persian Gulf waters.

Marine Environment – SEEN A SALP?

If anyone sees a salp in Irish waters, notify the authorities at once because these gelatinous sea creatures are another example of the alien species which are not welcome visitors. Last Spring they clogged intake pipes at California's Diablo Canyon nuclear-power plant which caused it to be shut down. Now they have shown up on the Washington coast, having somehow rounded the USA. Some fishermen have found them in nets and older fishermen can remember when they were last seen 30 years ago. Marine scientists have no idea why they are arriving in big numbers. "Weird," is one description.

salp

They look like a jellyfish, about the size of a human hand, with a hard head and a few tentacles. Scientists describe a salp as a pelagic tunicate which lives in the open ocean and has a tubelike body that pumps water for locomotion and to filter the plankton on which it feeds. Despite its translucent appearance, it is not closely related to jellyfish. It's a chordate, which means it has a spinal cord and is related to vertebrates. Salps can swim alone or in rope-like colonies. They have the ability to reproduce rapidly and can bloom when the plankton supply is rich. Marine scientists disagree as to whether their appearance is a sign of climate change in the sea.

Boats Wanted – DISCARDS AND SELECTIVITY

The State fisheries board, Bord Iascaigh Mhara, is going to carry out trials aimed at minimising discarding of fish and improving the use of fishing gear to avoid by-catches. Fishing vessel owners who would like to offer their vessels for use in the trials, as well as fishing gear and chandlery suppliers, are being invited to contact BIM, Crofton Road, Dun Laoghaire, Co.

#Missing - A body recovered from the sea off north Co Dublin yesterday may be that of a man who went missing from Rush at Christmas.

The Irish Independent reports that a post-mortem is being carried out on the body to confirm if it is that of 24-year-old Paul Byrne, who was last seen in the early hours of Christmas Day.

Fishermen in the Irish Sea made the grim discovery in their nets yesterday and brought the body to Skerries harbour after 8pm.

#Fishing - Minister for the Marine Simon Coveney will be seeking agreement from his European colleagues at next week’s Fisheries Council on how when and how introduce an effective discards ban in the context of the reform of the Common Fisheries Policy (CFP).

At the June 2012 Fisheries Council, ministers did not reach agreement on how a discard ban would be implemented or when such a ban would be introduced.

The challenge for Minister Coveney as president of the European Council of Fisheries Ministers is to secure wide agreement at council on an ambitious early date for the introduction of a ban in all waters across the EU from the Baltic & North Sea to the North Eastern Atlantic, the Mediteranean and the Black Sea.

Ministers will need to agree the practical measures that will ensure that the ban is capable of being effectively implemented in all these areas.

In a review of global discarding, the Food and Agriculture Organisation of the United Nations (FAO) noted that the North East Atlantic has the highest discard level in the world, estimated at 1.3 million tonnes, the majority attributed to EU fisheries. The EU Commission itself estimates that 23% of all fish caught by EU vessels are discarded.

Discarding occurs in almost every fishery, in every area and across most fleets in the European Union. Every member state operating fishing operations on the open sea has a discard problem. Many member states have significant levels of discards in certain fisheries, and for varying reasons.

The policy to stop discarding of fish and to change behaviour of fishermen so that unwanted by-catches and juvenile fish are no longer caught must be seen as an integral part of fisheries management in general and serve the overarching goals of moving to long-term management based on ecosystem considerations and reaching maximum sustainable yield by 2015, where possible, and by 2020 at the latest for all stocks.

The three European institutions, all member states and importantly the Irish presidency are fully supportive and committed to the introduction of a discard ban.

A very important element of delivering the overall objective will be the introduction across all fisheries of smarter and more selective fishing gear, strengthened selectivity measures and changed fishing practices that avoid to the greatest extent possible unwanted catches particularly those of juvenile fish.

To assist the debate on discards and facilitate actions to resolve the problem, Ireland published a 'Discards Atlas' detailing the full extent of discards by the Irish whitefish fleet. It is critically important that other member states do likewise to support the introduction of the new policy and inform measures that will be needed to ensure that a new policy is fully implemented by EU fishing fleets.

Minister Coveney commented: "I am and continue to be a strong advocate for a policy which eliminates the wasteful practice of discards.”

On the prospects for council, he said: “I am under no illusion of the challenges the effective implementation of a discards policy pose for European fishermen and for the member states of the EU, and will work intensively with my European ministerial colleagues over the course of the February Council to deliver a policy with an ambitious timetable for implementation that will end the discarding of fish and support the rebuilding of fish stocks and the future of coastal communities depending on fishing.

"It is my firm belief that the success or failure of the reformed CFP will be judged to a large extent on the effectiveness of whatever discard ban is introduced and that there is widespread support for the ban from the fishing nations of the EU and their fishermen.

"It is imperative that European fisheries ministers collectively take this progressive but challenging decision now and co-operate in agreeing appropriate and effective measures to eliminate discards with ambitious timelines."

Agreement in the council will free up the Irish presidency, on behalf of the council, to begin negotiations with the European Parliament and Commission to reach political agreement on a new reformed Common Fisheries Policy by June.

#IrishHarbours - Funding of €7.4 million for urgent remedial works at six regional harbours has been announced by Minister for Transport, Tourism & Sport Leo Varadkar.

The funding will pay for repairs and safety works on essential harbour infrastructure, and is likely to benefit the local economy, promote leisure activities and support the fishing industry.

“This funding will allow essential works at these regional harbours on piers, walls and harbour structures," said the minister. "This work is necessary as part of their transfer from central Government to local authority control.

“Harbours play an important role in their communities in terms of fishing, cargo and leisure and play an increasingly important role in tourism and watersports."

Minister Varadkar added: "The large-scale safety or construction projects planned for Kinsale, and for Baltimore & Skibbereen Harbour this year will be able to go ahead thanks to this funding. Smaller scale projects at other harbours can also proceed, including essential works at Arklow Harbour.”

The funding has been allocated to the following harbours:
 
Arklow - €3,588,000
Baltimore & Skibbereen - €1,165,000
Bantry Bay - €100,000
Kinsale - €1,467,000
Tralee & Fenit - €750,000
Wexford - €329,500
 
The funding has been concentrated on remedial works to ensure that the harbours are in a fit condition during their transfer to local authority control.

Twelve of the 13 regional harbours have transferred to date, with 11 being taken over by local authorities, and one designated a fisheries harbour.

#Coastguard - The Irish Times reports that a fisherman has died after sustaining head injuries in an incident off the Old Head of Kinsale last night.

The man, one of three crew on the West Cork-based fishing trawler Liberty, is believed to have died from his injuries on board the vessel.

According to TheJournal.ie, the Courtmacsherry RNLI lifeboat and Irish Coast Guard helicopters from Shannon (Rescue 115) and Waterford (Rescue 117) were all scrambled to the scene.

The deceased was airlifted by Rescue 117 to Cork for transfer to hospital, while the remaining crew returned to Kinsale this morning with the lifeboat crew.

It is thought that the accident involved trawling wires on board the fishing boat.

#MCIB - The dangers of performing maintenance tasks on boats while machinery is running have been highlighted in the official investigation into an accident on a fishing vessel off Erris Head in Co Mayo last year.

The skipper of the MFV James Collins was seriously injured when his leg was caught in the vessel's propeller shaft while attempting to clear debris from the bilge pump on the morning of 20 April 2012.

Jonathan O'Donnell, aged 26 at the time, suffered significant soft tissue damage to his left leg and broke his trivia, fibia and ankle in the incident. Luckily the leg did not require amputation and he is expected to make a full recovery.

The report into the incident by the Marine Casualty Investigation Board (MCIB) found that the vessel's bilge pump was located in the hold adjacent to the propeller shaft, with access to both prevented by the same covering boards.

When O'Donnell responded to a persistent bilge alarm, he did not put the engine on stop or into neutral and the propeller shaft remained turning when he removed the covering boards to access the pump.

As he put his foot into the bilge beside the shaft in order to reach down and clear debris, his waterproof leggings were caught by the coupling on the shaft and his leg was round around it twice.

The MCIB noted the quick actions of the vessel's crew and the prompt attendance of RNLI lifeboat and Irish Coast Guard helicopter crews as instrumental in O'Donnell receiving swift treatment and not losing his leg.

However, the report also pointed to a lack of attention to proper safety precautions on board, nothing that the skipper was "too intent on solving the bilge pump problem" and that he "neglected basic safety procedures" by not stopping all machinery before accessing the bilge as set out in the Code of Practice for Fishing Vessels.

The report concluded that the "ease with which debris could enter the bilge and block the pump suction" was a contributing factor to putting the skipper in his predicament at the time, and also referenced the ease with which loose-fitting clothing like waterproofs can be snagged on turning machinery.

Moreover, the screening of the propeller shaft by covering boards also used to access the bilge pump did not present adequate protection "enabling it to be easily exposed and present a hazard".

The MCIB recommends that the Code of Practice be amended to highlight the danger of accessing the bilge area when shafts are rotating, and to include assessment of sole boards in fish holds to prevent debris passing through to the bilge tank. The complete report is available to download below.

#CFPReform - Minister for the Marine Simon Coveney, in his capacity as President of the European Council of Fisheries Ministers, last week welcomed the vote by the European Parliament on the reform agenda for the Common Fisheries Policy (CFP) which has been prioritised for delivery by the Irish EU presidency.

The vote, which is seen a major step forward in the CFP reform process, follows the minister’s address to parliament on Tuesday last. At the address the minister appealed for all parties to work together towards an agreed CFP reform package to be delivered during the period of Ireland’s presidency.

These reforms, which prioritise long term sustainability of fishing stocks, elimination of the controversial practice of discards (dumping at sea) and a switch to long-term (scientifically based) planning for fisheries, were  approved by the parliament on Wednesday 6 February.

The decision of the parliament follows the minister’s address last Tuesday during which he identified the reforms as a major priority on the Irish Government’s EU presidency agenda.

Minister Coveney stated: “I am delighted that the parliament has today decided to back these necessary and timely reforms to the Common Fisheries Policy and that the case for reform outlined in my recent address has been accepted in an agreed manner.

"I am particularly encouraged that this vote has occurred during the Irish EU Presidency. This shows the pivotal role which Ireland can play in influencing broader European Policy and in bringing together divergent views towards an agreed reform package for the CFP.

"Ireland has set out an ambitious work programme aimed at delivering an agreed reform package for the CFP by the end of June. This objective can only be realised if [European] Parliament, Council and the Commission work together focusing on the bigger picture of an agreed reform agenda to benefit all of Europe’s citizens.”

During his address to the plenary session of European parliamentarians, Minister Coveney expressed his view that a momentum was now gathering behind the drive to deliver an agreed reformed CFP package by the end of June.

Acknowledging to the parliament that he had set out an ambitious work programme for his presidency, the minister accepted that differences remain between the European Council and Parliament, particularly on the question of multi-annual fisheries plans.

Minister Coveney emphasised the significant areas of common ground between both institutions and his belief that this would eventually lead to an agreed way forward on most aspects of the reform package. He stressed that it was only in a framework of mutual cooperation and flexibility that the objective of a reformed CFP which prioritises long term fisheries sustainability could be delivered in the lifetime of the current Irish Presidency.

The minister acknowledged the challenges ahead and emphasised the importance for the EU Parliament, Council and Commission to work together on all the issues including delivering on maximum sustainable yield, the elimination of discards and regionalisation.

Following an exchange of views, the minister sought support for his objective of achieving political agreement by the end of June in addition to acceptance of the need for a different and more effective way of working to deliver on what is a commonly held objective. He committed to working constructively with the parliament on all outstanding issues.

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.
