#MarineWildlife - Whale watchers on Slea Head were treated to a special sight earlier this week with the surprise appearance of the killer whale known as John Coe, as the Irish Examiner reports.

Landscape photographer Richard Creagh was among the lucky few on Monday (27 June) to spot the orca known by the distinctive notch on his dorsal fin – though in more recent times he's also lost a chunk of his tail fluke, most likely to a shark bite.

Creagh, a keen marine wildlife watcher for the last 10 years, said: "Up to now killer whales had always eluded me but today I got to add them to my list, and what a sight it was! I’m still buzzing!"

John Coe's unique orca pod are regular visitors to Irish waters, though he himself was last spotted close to our shores almost three years ago at the Inishkeas in Co Mayo, according to the Irish Whale and Dolphin Group – which is asking the public to watch the seas for any more sightings of the senior cetacean.

#Fishing - 'Money for old rope' is the pitch for a new initiative that aims to recycle old fishing nets that often end up littering the seas, as the Irish Examiner reports.

A number of Irish companies have been invited to Norway later this year to explore the possibility of collecting abandoned fishing nets and other ocean waste for repurposing in various industries – such as using the rope fibres in reinforced concrete.

They will be led by Macroom E, a company started by Cork County Council to help small and medium businesses make the most of recycling initiatives.

Macroom E is a partner with Circular Ocean, a Europe-wide project hosting a showcase this September on its work to remove waste from the ocean – where plastic and 'ghost nets' remain a hazard to marine wildlife – and turn it into a useful, and profitable, resource.

#Larne - Coastal wildlife in Co Antrim is under threat after a significant diesel spill from a Caterpillar plant in Larne at the weekend, as the News Letter reports.

The plant machinery firm faces likely enforcement action after 40,000 litres of red diesel leaked into Larne Lough via a storm drain – news of which was not made public till days later, according to the Belfast Telegraph.

As the Northern Ireland Environment Agency moved to assure that the spill's impact on marine life would be minimal, conservationists remain concerned as the diesel slick was seen drifting towards The Gobbins, home to many protected seabird species.

Spot checks of affected parts of the Antrim coast have as yet found no injured birds, but Ulster Wildlife maintains that the spill "could have potentially devastating impacts on breeding birds".

#BlueWhale - The skeleton of a blue whale beached in Ireland that's to be the centrepiece of London's Natural History Museum has been held together by old newspapers for more than 80 years, it has emerged.

Afloat.ie previously noted the Irish origins of the giant marine mammal remains that were recovered from the Wexford coast 125 years ago – and is next year set to replace Dippy the diplodocus in the London museum's atrium.

But as Kent Online reports, it was only recently discovered that parts of the massive skeleton were being held together with copies of the Kent Messenger newspaper from the 1930s.

Staff responsible for the careful reconstruction of the blue whale specimen found dated newsprint within the plaster-like material that had been used as 'stuffing' to pack out and hold together its bones.

According to a museum spokesperson, it indicates strong connections between the English county and the workers in London who prepared the whale for display.

#Fungie - Dingle's resident dolphin Fungie has sustained a significant wound below his dorsal fin, as the Irish Examiner reports.

The deep cut, likely inflicted by a visiting boat's propeller, was noticed yesterday (Friday 3 June) by fans of the popular marine wildlife attraction who's delighted locals and visitors alike in Dingle for more than 30 years.

However, Fungie lovers have been urged not to panic – as the famous bottlenose has healed well from similar injuries before, and has already returned to frolicking with boaters in Dingle Harbour.

#BowheadWhale - The search continues in tracking down the elusive bowhead whale that's excited marine wildlife experts since it was sighted in Carlingford Lough at the weekend.

One of a species never before recorded in Irish waters in the 25 years since the Irish Whale and Dolphin Group (IWDG) was formed, the 20ft juvenile whale was photographed from a pilot boat at the mouth of the lough at the Helly Hunter Rocks on Sunday 29 May.

It's thought that it may be the same individual from the arctic species spotted off Cornwall in mid May, following a previous bowhead sighting at the Scilly Isles in February.

The Celtic Mist joined the hunt yesterday (Tuesday 31 May) on its circumnavigation of Ireland and failed to make any sighting, though bowhead whales are known for being difficult to spot due to their lack of a dorsal fin.

The IWDG has much more on this story HERE.

#MarineWildlife - Months after she was found on the streets of Galway, the seal pup named Poison Ivy has returned to the sea at Galway Bay with a group of fellow rescued seals.

As previously reported on Afloat.ie, Ivy was no more than three weeks old when she was picked up by council workers on a Salthill footpath last December.

Though seriously ill, she fought her way back to health under the watchful eye of the staff at Seal Rescue Ireland in Wexford, who gave her a name in keeping with their comic-book theme.

But it was back to Salthill she went this past weekend when Ivy was released into the wild at Ladies Beach, according to Galway Bay FM.

#Turtles - Two rescued loggerhead turtles have been returned to the ocean by the crew of LÉ Róisín as the Naval Service vessel makes its way to the Mediterranean on deployment.

According to RTÉ News, the Naval Service were only happy to oblige when contacted by Dingle Oceanworld about the possibility of releasing Una and Tallula.

The former was nursed back to health at the Dingle marine wildlife sanctuary after she was found at Barryroe in West Cork last December.


She was joined on the OPV by Tallula, a turtle washed up in Cornwall who was treated at Newquay's Blue Reef Aquarium and flown into Dingle especially for release.

As previously reported on Afloat.ie, LÉ Róisín and its 57-strong crew are headed to the Mediterranean as the first deployment for the Naval Service this year under Operation PONTUS.

#MarineWildlife - Places are going fast for a special cruise on board the Irish Whale and Dolphin Group's Celtic Mist to celebrate the 25th anniversary of Ireland's whale and dolphin sanctuary.

Celtic Mist will depart Fenit, Co Kerry next Saturday 7 May with a team of IWDG members and marine science experts on an almost three-month circumnavigation of Ireland, first heading north along the Wild Atlantic Way and around to the Irish Sea, calling on Dublin on 7 June to mark the 25th anniversary of the Irish Government's official declaration of this island's waters as a sanctuary for cetaceans.

The declaration came only three months after it was proposed by the then newly formed IWDG, and both have been instrumental in raising awareness of the bounty of marine wildlife in Irish waters.

Though berths on the voyage are filling fast, everyone will have the opportunity to participate by assisting in outreach events along the cruise route, or by tracking its progress online. Details on how to get involved can be found on the IWDG website HERE.

Along the way passengers on Celtic Mist may be treated to some of the incredible wildlife the sanctuary was created to protect, such as humpback whales – a number of which were spotted on an early visit to West Kerry earlier this month, likely attracted by schools of sand eels, as the IWDG reports.

In other marine wildlife news, locals near a beach close to Ballyshannon in Co Donegal have complained after a whale carcass was left rotting on rocks three days after it was reported to authorities.

According to the Irish Mirror, successive high tides had failed to shift the 25ft minke whale, though Donegal County Council says it is arranging for the animal's disposal.

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.
