#MARINE WILDLIFE - At least two humpback whales have been spotted by birdwatchers off Galley Head in West Cork, according to the Irish Whale and Dolphin Group (IWDG).

"This is the first time since the large whale project commenced in 1999 that humpback whales have been recorded along the Irish south or coast during April, which has been up till now the one month in which large whales have consistently been absent from our inshore waters," said IWDG sightings co-ordinator Pádraig Whooley.

The timing of this sighting was described by Whooley as "unusual". He also confirmed that one of the whales was recorded off Hook Head in Co Wexford in late January and early February of this year, which dispells the hypothesis that large whales leave Irish waters after the herring season in the southeast.

Meanwhile, Whooley sounded a word of caution for anyone hoping to spot the humpbacks for themselves, as the "sheer numbers of basking sharks about" often result in false sightings.

#MARINE WILDLIFE - A meeting of the Northern Ireland Marine Task Force (NIMTF) last week brought together interests from across the spectrum to discuss the new Marine Bill and ensure it will "deliver for all sea users".

The workshop at Castle Espie on Strangford Lough last Thursday 22 March saw politicians sit down with environmentalists, fishermen and wind farm developers, and engage with those responsible for drafting the proposed legislation.

According to a statement from the Ulster Wildlife Trust, which is a member of the NIMTF, the bill "provides for the creation of a network of marine protected areas to protect marine wildlife" as well as a roadmap for a more joined-up approach to the North's marine resources.

NIMTF spokesperson Ricky Devlin said: "We now need to ensure that [the bill] addresses the full range of environmental, recreational and commercial interests such as fishing, diving, electricity generation and aquaculture."

A full report of the meeting will be available shortly from www.nimtf.org

#MARINE WILDLIFE - Staff and students from the Galway-Mayo Institute of Technology spotted an black-browed albatross in what was a "very rare" sighting of the bird in Ireland's skies, The Irish Times reports.

The group was on board the State marine research vessel Celtic Explorer off the southwest coast when they witnessed the albatross, also known as a Mollymawk, which is noted for its dark eye stripe.

The black-browed albatross is normally restricted to the Southern Hemisphere, but Birdwatch Ireland's Niall Hatch said it has been spotted from headlands in Ireland in the past.

As previously reported on Afloat.ie, the GMIT group were among a party of 20 scientists from Ireland, Nothern Ireland and Scotland carrying out a study of whales, dolphins, seabirds and plankton in the Atlantic.

#MARINE WILDLIFE - Northern Ireland's Green Party has warned that "rogue" anglers may shoot seals that are consuming their fish stocks unless they are relocated, the Belfast Telegraph reports.

The protected seals have been getting into the River Quoile in Co Down, allegedly by way of a damaged fish pass, and decimating the area's fish stocks - much to the consternation of local anglers.

Earlier this week Leisure Minister Carál Ní Chuilín confirmed in a response to a question from Green Party MLA Steven Agnew that department officials have requested the Rivers Agency to carry out repairs on the fish pass.

But she also said that no action can be taken to remove seals from the river "without the approval of the Northern Ireland Environment Agency", adding that her department "does not have the specialist knowledge and equipment to remove the seals".

A Green Party spokesperson described the repair work as "absolutely vital because even if the seals are safely removed from the Quoile they will only make their way back in if the fish pass is not repaired.

"And a rather worrying consideration is that a very small rogue element would be prepared to shoot the seals if a solution is not forthcoming.”

Seal shootings have been much in the news as of late, with gardaí in Waterford investigating attacks on four animals in Tramore.

#MARINE WILDLIFE - Two killer whales have been spotted near Kinsale in recent weeks, the Irish Whale and Dolphin Group (IWDG) reports.

Two separate sightings of the orca pair near Barry's Head have been confirmed by the group, via photos provided by John Murphy and Richard Cussen on 5 March, during what is normally the 'low season' for whale watching in Ireland.

The pair comprises one adult male and a smaller whale which is likely an adult female. It is not yet known, however, whether the whales are new to Irish or Scottish waters.

According to the IWDG's Pádraig Whooley, it is "interesting that they have stayed close to their original position and suggests they may have found 'rich pickings'".

In other news, the Whale and Dolphin Roadshow will be at the Galway Shopping Centre from 22-25 March in time for the European Cetacean Society Conference.

The roadshow "is a fantastic opportunity to learn more about whales, dolphins and porpoise of the ASCOBANS region" that encompasses the Baltic Sea, Northeast Atlantic and Irish and North Seas.

#MARINE WILDLIFE - Northern Ireland faces a whopping £8 million (€9.6 million) fine from the EU over its failure to protect horse mussels.

According to BBC News, "little has been done" to protect horse mussel reefs in Strangford Lough despite promises from two government departments as far back as six years ago.

Last year Afloat.ie reported on a study from Queen's University Belfast that revealed the extent of damage to horse mussel reefs in the lough by fishing activity.

Strangford Lough is officially protected as a Special Conservation Area and a Marine Nature Reserve, as well as an Area of Special Scientfic Interest, but as BBC News states, "in reality there has been little protection put in place".

Horse mussels are pivotal to the lough's ecosystem, as some 100 other species rely on the reefs formed by the mussels in the seabed for their habitat.

NI officials now have just a few months to persuade the European Commission that they are taking strong action to protect the species, otherwise they will be charged with breaking EU directives.

#MARINE WILDLIFE - The rate of cetacean strandings on the Irish coast remains unusually high, according to the Irish Whale and Dolphin Group (IWDG).

The group's Cetacean Stranding Scheme recorded 162 strandings in 2011 which, while numbers do vary from year to year, was 25-30 more than anticipated.

And already this year the numbers are up on last year's 'inexplicable' records for the first quarter.

Some 21 strandings were reported to the IWDG in January alone - the highest ever number recorded for that month, well above the average of 13.

February's figures are even more worrying, with 30 strandings reported this year compared to a five-year average of 11.4.

"As we are now well into 2012, it is clear that the numbers have not returned to what we could have considered to be more normal levels," said the group in a statement.

There is as yet no explanation, whether a single cause or a number of factors, for what might be causing this significant rise in strandings of both live and dead animals, although one curious clue is "the number of carcasses which had washed ashore with tail fluke/fins apparently cut away".

In other IWDG news, the group recently announced the receipt of £2,000 (€2,400) core funding support from Scottish-based veterinary X-ray firm BCF Technology Ltd, which funds a number of charities through its BCF Foundation.

#MARINE WILDLIFE - A Sligo-based surfer has relived the moment when he was attacked by a shark in his native New Zealand.

As the Otago Daily Times reports, 42-year-old Peter Garrett was surfing off Taranaki on North Island on Tuesday when the shark mauled him, leaving 10 bloody wounds - each about 2cm deep - with its razor-sharp teeth.

"He was bleeding quite a bit," said James Bruce, one of two vets surfing in the area who came to his aid. "You could tell from the teeth marks it could've been more serious."

Speaking to the Irish Independent from New Zealand, Garrett said he was knee-boarding at the time when he felt a bump to the board and a sudden sharp pain in his leg.

"I looked down and there was a shark on my leg and I sort of yelled obscenities at it... But it came back and I kicked at it with my flippers."

New Zealand has a relatively high incidence of unprovoked shark attacks, with some 44 on record since the mid 19th century - compared to 39 for the whole of Europe.

#MARINE WILDLIFE - The Limerick branch of Birdwatch Ireland is seeking volunteers to assist in rescuing birds from oil spillages in the Shannon Estuary.

A report in the Limerick Post recounts a recent meeting at Shannon Rowing Club, where Birdwatch Ireand highlighted the impact on the environment and marine wildlife from both major and minor oil spills.

The meeting also discussed the role that local birdwatchers can play in determining crucial spillage incident response times.

A training exercise at Poulnasherry Bay is being organised for next month using equipment donated to the Irish Seal Sanctuary, preceeded by a similated planning exercise and "on-the-ground response".

The Irish Seal Sanctuary will also provide opportunities for training in the rehabilitation and cleaning of spillage-affected birds.

#MARINE WILDLIFE - Newstalk reports that gardaí are investigaing the shooting of seals on a Waterford beach.

As previously reported on Afloat.ie, fears are mounting of an illegal cull of marine wildlife in the area after a seal and a dolphin were found dead from gunshot wounds within a day of two seals being discovered with similar wounds.

All four animals were found along the same stretch of Tramore Beach late last month.

A spokesperson for the Irish Seal Sanctuacy pointed the finger at an illegal cull allegedly carried out by local fishermen.

The Irish Wildlife Trust has welcomed the Garda investigation into the incidents, and has called on the public to report any relevant information they may have.

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.
