Ireland has a new resident dolphin, as a solitary bottlenose seems to have made its home in Carlingford Lough — and locals have voted to name it ‘Finn’.

Nearly 3,000 people took part in the Facebook poll in which Finn (the Anglicisation of Fionn) won out over ‘Bobby’ in a landslide.

“As we don't know if the dolphin is male or female, Finn works well as it is a popular name for both boys and girls,” the Carlingford Lough and the Cooley Peninsula Facebook page said.

“But if we can call our famous legend Finn or Fionn, we are sure the dolphin won’t mind.”

The Dundalk Democrat reports that Finn has been recently sighted ‘belly flopping’ near the port of Greenore — but marine wildlife experts warn that this may be a sign of distress.

Particularly in light of reports that a snorkeller was seen swimming close to the dolphin, all water users are to be reminded that it is a wild animal and advised to keep their distance.

The traditional first day of spring in Ireland also saw the return of Nimmo, a bottlenose dolphin who’s become a regular visitor to Galway city.

The Irish Whale and Dolphin Group (IWDG) says this is the sixth consecutive year for this particular dolphin, who has stayed for anywhere between four and eight months since 2016.

As reported this time last year on Afloat.ie, Nimmo’s predilection for Galway Harbour is a sign that the area has become an important feeding habitat.

“This is a wonderful opportunity for people in Galway to observe a wild dolphin close to a city centre and often within clear view of the shoreline,” says IWDG sightings officer Pádraig Whooley.

He also calls on local citizen scientists and marine wildlife watchers to submit their own sightings over the coming months.

A bottlenose dolphin was recently rescued by quick-thinking locals after live stranding on Mutton Island near Galway city.

The Irish Whale and Dolphin Group (IWDG) reports the story related to it by friend of the group Jason, who was alerted to the marine mammal in the shallow water near the Galway Bay lighthouse by an Australian couple with whom he had previously been discussing the area’s resident bottlenose Nimmo.

“I just knew it was in trouble so I ran down and the dolphin was out of the water alive,” he said.

With the tide going out, time was of the essence as Jason was joined by three others who offered their scarves to form a brace to lift the dolphin into deeper water.

“I just went the rest of the way as it was getting dark at that point. With one final push it just started to swim away.

“I can’t explain how I felt and we did it as a team. An incredible thank you so so much to those who helped,” he added.

The incident came just days after the IWDG called on the Government to join forces with NGOs like itself to develop a stranding response protocol, especially for large whales.

The IWDG said “fresh attention” has been drawn to the issue following the death of a fin whale seen swimming in Dublin Port earlier this month.

More recently, an endangered sei whale was found floating in the River Thames at Gravesend in the UK last Friday (18 October), nearly two weeks after a humpback whale died in the same stretch of water.

IWDG chief executive Dr Simon Berrow said: “Strandings, both live and dead, of large whales are not common in Ireland but do occur and we need a protocol, signed off by relevant partners, including Government agencies, so we can respond quickly and efficiently in such cases without having to phone around looking for resources and support.”

#MarineWildlife - Galway residents have a great opportunity to see a wild dolphin close to the city centre with the return of regular visitor to the Nimmo’s Pier area this week.

Nicknamed Nimmo, the solitary bottlenose dolphin was first sighted in the city in April 2015 and since then has become an annual fixture, appearing and staying longer each time.

The Irish Whale and Dolphin Group (IWDG) suggests this is a sign that the area around Galway city is now a “more important core feeding habitat for Nimmo”.

In other news, the IWDG’s research vessel Celtic Mist will embark on a series of week-long surveys this summer in search of humpback whales.

IWDG members are invited to join any of the nine legs, the first of which sets sail from 9-15 June (weather permitting) between Cork and Dingle/Fenit.

#MarineWildlife - Marine wildlife fans in the Dublin Bay area will be on the lookout for a group of bottlenose dolphins that have been spotted between Killiney and Dun Laoghaire.

It's the first sighting of the species off South Dublin since August 2012 when a pod of three dolphins that had delighted local residents for two years, as previously reported on Afloat.ie, moved on around the coast towards Kerry and beyond.

According to Irish Whale and Dolphin Group sightings officer Pádraig Whooley, it's not clear whether this is the same group of two adults and a juvenile returning to their previously regular haunt.

But with regular reports of sightings between Scotsman's Bay, Bullock Harbour and Killiney Bay since 2 January, there will surely be plenty of opportunity to get the necessary photographic evidence.

#MarineWildlife - Two months after striking up a friendship with fellow 'dolphina-non-grata' Dusty in his travels around Ireland, 'bad boy' bottlenose Clet has moved on again - this time to the west coast of Scotland.

According to the Island News & Advertiser, Clet appeared in the Sound of Mull in the Inner Hebrides during the week - his first confirmed sighting after he was seen frolicking with Dusty in Galway Bay - making for a rare sighting of a solitary dolphin in the area.

“To our knowledge, this is the first time that Clet has been recorded in Scotland, and in fact this is the furthest north he has been recorded to date,” said Dr Conor Ryan, sightings officer with the Hebridean Whale and Dolphin Trust.

Pádraig Whooley of the Irish Whale and Dolphin Group (IWDG) also hailed Clet's reappearance, saying: "The addition of Scotland after a two-month interval brings his known tally of passport stamps to five countries and counting, and shows the need for international collaboration when trying to monitor these highly mobile marine mammals.”

But Scottish dolphin-watchers be warned, as Clet may have been involved in an act of aggression towards swimmers near Galway city in early October.

#MARINE WILDLIFE - A stranded dolphin has been successfully refloated for the first time ever in Ireland thanks to the efforts of volunteers with the Irish Whale and Dolphin Group (IWDG).

As the Irish Examiner reports, the group was alerted by a woman who saw the 3.5-metre bottlenose dolphin on a beach at Béal on the Shannon Estuary in north Kerry on 1 June.

Volunteers on the scene discovered the female dolphin's skin was still moist, which indicated it had only recently stranded.

After checking for injuries, the team decided not to wait for special whale pontoons to arrive from Kilrush and instead used a local farmer's tractor and low loader to lift the dolphin out of the sand.

The dolphin was slowly moved back to the water, where she was stabilised before she regained composure and was able to swim away.

Images of the dolphin's dorsal fin were captured by the volunteers for the IWDG's records, which enabled researchers to confirm subsequent sightings among a pod of some 140 dolphins swimming in the estuary - with the latest spotting on 27 June on a dolphin-watching boat trip, where she appeared to be in good health.

In a statement, the IWDG said: "The loss of one dolphin, especially an adult female, could have a significant impact on this population, thus highlighting the importance of the prompt action on the shore at Béal."

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.
