Diving in for a cool swim after a car journey in warm weather may seem tempting, but it multiplies the risk of drowning, Water Safety Ireland has warned.

As The Sunday Independent reports, the appeal has been issued on the eve of the UN’s first world drowning prevention day  – and after six people died in swimming-related incidents over the past week.

“Even if we have slightly cooler weather to come, travelling in a warm car increases the body’s core temperature, “ Water Safety Ireland chief executive John Leech explains.

“This exaggerates the impact of cold shock if one jumps into the water,” Leech says.

Cold shock can induce uncontrolled breathing which can increase heart rate and blood pressure and cause cardiac arrest.

Water Safety Ireland has appealed to people to swim only in lifeguarded areas or on waterways where there is good local knowledge, with shallow shelving allowing people to remain safely their depth.

It is also reminding people never to use inflatable toys in water, to supervise children closely, to wear a lifejacket when on a leisure craft, and to avoid mixing alcohol with water activities.

Buildings and structures including Dublin Port’s diving bell will be illuminated in blue for UN world drowning prevention day, an initiative that was spearheaded by Ireland and Bangladesh.

Ireland records an average of 115 drownings annually.

In the decade to 2020, drowning was responsible for 1,151 deaths in Ireland - and over 2.5 million preventable deaths worldwide.

During the month of June alone, there were 27 rescues by lifeguards in five counties, according to figures supplied to Water Safety Ireland.

Lion's mane jellyfish

Meanwhile, there have been sightings of Lion's mane jellyfish on the east and west coasts at Malahide in Dublin, Mullaghmore in Sligo and Ballyvaughan, Co Clare.

A sting from a Lion's mane can cause nausea, sweating, cramps and headaches.

A spokesman for Sligo County Council warned that people can get into difficulties from panic caused if stung by one of these particular jellyfish.

Fatalities on inland waters

Five of the six fatalities in the water this week occurred inland.

Jay Moffett (13) died in Scarva, Co Down on Monday after he got into difficulty while swimming with friends, and Killian Casey (15) died in hospital late this week after he was rescued from Lough Sheelin, bordering Cavan, Westmeath and Meath on Tuesday afternoon

A 55-year old man named locally as Peter Jones died in Lough Melvin, Co Fermanagh on Wednesday morning.

On Wednesday evening, 29-year-old mother of two Natasha Corr lost her life at Swan lake outside Gowna village on the Longford-Cavan border.

Also on Wednesday,a man in his seventies named locally as Michael Hoey died in a snorkelling incident at Spencer Harbour, Drumkeeran, Co Leitrim.

A man in his sixties died at Dollymount strand, Dublin, on Friday in a suspected case of cardiac arrest.

Portaferry Coastguard Rescue Team on Strangfrod Lough in Northern Ireland has warned of hundreds of Lion's Mane jellyfish washed up on the shore at Cloughey on the eastern coast of the Ards Peninsula. It's a small village with a beautiful sandy beach.

The team warned that anyone finding a Lion's Mane jellyfish should be aware that the tentacles of this species retain their potent sting long after the jellyfish has died, and dead specimens should therefore never be touched under any circumstances; and that if a dog comes into contact with a Lion's Mane Jellyfish, immediate veterinary attention is advised as anaphylactic reactions are not uncommon.

This jellyfish uses its stinging tentacles to capture, pull in, and eat prey such as fish, zooplankton, sea creatures, and smaller jellyfish and the largest recorded was measured found of the coast of Massachusetts in 1865 and had a bell 7 feet diameter and tentacles around about 120 feet long.

Dun Laoghaire-Rathdown County Council has put up warning signs in the lifeguarded area of Sandycove in south Dublin after sightings of lion’s mane jellyfish in the water.

Though the notice was put in place yesterday (Thursday 13 June), it’s emerged there have been sightings of the venomous marine wildlife since mid-May.

Bathing has not been prohibited as it was with the water quality warning earlier this month.

But swimmers at Sandycove and further out in Dublin Bay are advised to proceed with caution for the time being.

As an added precaution the lifeguard warning flags are on red and will remain in place till further notice, the council says.

Lion’s mane jellyfish carry a painful and potentially lethal sting, even when washed up on the beach.

Last summer saw more than 150 lion's mane jellyfish recorded along the West Coast — amid a spate of incidents with swimmers being stung in Galway Bay.

But the East Coast was not immune, as a teenager was hospitalised after he was stung over most of his body off a Co Louth beach.

#Jellyfish - A whopping 157 lion’s mane jellyfish were recorded along the West Coast this summer, according to figures from the National Biodiversity Data Centre.

And as Galway Bay FM reports, more than a third of these sightings (61) were in the Galway area alone.

Swimmers in Galway were first put on alert in June after a number of people were hospitalised by stings from the dangerous marine animal.

Lion’s manes around the Irish coast this year are believed to be larger than usual to due warmers waters as well as an absence of their natural predators.

Meanwhile, the Irish Mirror has news of a ‘ghastly’ find on a Donegal beach in the shape of a partially eaten fish wholly visible inside a jellyfish.

The “savage” remains of what’s thought to be a moon jellyfish — and its final meal — were discovered by Belfast comedian Paddy Raff.

#Jellyfish - Ireland’s recent invasion of lion’s mane jellyfish has extended from Galway Bay to the East Coast, where a teenager was hospitalised after a nasty sting in recent days.

Herald.ie reports that 14-year-old Jack Dunne was stung over most of his body after getting entangled in the tentacles of a lion’s mane while swimming with friends off Port Beach, near Togher in Co Louth.

The teen needed “strong antihistamines and anti-inflammatory tablets” to recover from the intense pain of the jellyfish stings, which have the potential to cause death from anaphylactic shock.

Irish Water Safety chief John Leech warned that the dangerous marine species is not normally seen in the Irish Sea till autumn — and may be increased in number due to an absence of their natural predators, sunfish and turtles. Herald.ie has more on the story HERE.

Lion’s mane jellyfish currently being encountered in Irish waters are also larger than usual, according to one animal expert.

#Jellyfish - Lion’s mane jellyfish in Irish waters this summer are much larger than usual.

That’s according to zoologist Dr Tom Doyle, who spoke to The Irish Times after a recent spate of incidents that saw swimmers hospitalised by stings from the dangerous marine species in Galway Bay.

“It is not correct to say this is the first time they have been spotted on the west coast, as we had reports for the last two years, but they are particularly large and mature,” said Dr Doyle.

Lion’s mane jellyfish are more commonly seen in the Irish Sea, and reports of larger specimens similar to those off Galway and Clare have come in from North Wales and Liverpool.

Dr Doyle appealed for the public to report any sightings to the National Biodiversity Data Centre as well as the Facebook page for The Big Jellyfish Hunt.

#Dublin Bay junior sailors turned up to race yesterday on what was arguably one of the best sailing days of the season so far only to learn the first race of their September Series was scubbed due to 'jellyfish reasons'.

It's just the latest shut down of leisure pursuits in the capitals waters after Dun Laoghaire Rathdown County Council warned against bathing in 'Jelly fish infested waters' at nearby Sandycove.

As a finale to the 2014 season, racing was scheduled for six dinghy classes including the Optimist, Laser Radial and 4.7, Topper, Feva and 420 classes but not even the fact that over 100 junior sailors drawn from the four dun Laoghaire yacht clubs would be on the water rather than in it could stop yesterday's cancellation of the harbour races, such is the risk posed by the Lions mane jellyfish.

Last week Dun Laoghaire Harbour Master Simon Coate wrote to the yacht clubs and classes. ' A considerable number of Lions mane jellyfish have been sighted within the harbour. Please warn your members,' Captain Coate advised.

#Jellyfish - The Irish Mirror reported on Friday that 17 dangerous lion's mane jellyfish were removed from Sandycove Beach on south Dublin Bay.

However, that may be just the tip of the iceberg in their numbers as the giant venomous species flocks to Ireland's warming coastal waters from elsewhere in the Irish Sea.

Meanwhile, restrictions on bathing have been lifted from nearby Sandycove Harbour and Killiney Beach after elevated bacterial levels were detected in the water earlier in the week.

Dollymount Strand's temporary bathing ban has also been lifted, as have a number of advisories in North Co Dublin.

However, precautionary notices remain at three locations – Burrow in Sutton, Claremont in Howth and Loughshinny Beach between Rush and Skerries – due to poor results of samples collected from outfalls at those locations.

Michael Viney writes in The Irish Times on growing concerns over lion's mane jellyfish and other harmful species in Irish waters.
The lion's mane is among the largest jellies found in Ireland and comes with a powerful sting, enough to disrupt "the stoical bliss normal to Dublin's Forty Foot bathing cove".
"Last year, the jellyfish was even more abundant in the Irish Sea than in 2009, and sightings from ferries found them from coast to coast," says Viney, who notes their and other jellies' dangerous effects on the marine industry and ocean ecosystems.
The decline of certain plankton-feeding species such as herring due to overfishing, coupled with a rise in sea temperature, has led to a marked increase of jellyfish of many different species in our waters such as the mauve stinger, which is blamed for decimating a Co Antrim fish farm's entire salmon stock.

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.
