The Christmas season is a time when thousands of people around the country will take to our waters to support sponsored swims for charitable causes say Irish Water Safety. This year we have a full moon on Christmas day which is the first time we have experienced this since 1977 and the next time will be in 2034. This will cause strong tidal streams around our coast and cause rip currents to increase in strength and speed.
Christmas day charity swimmers occasionally take chances beyond what is acceptably safe, finding themselves left without sufficient strength to climb out of the water due to the cold.
Cold winter waters can cause "cold shock" and hypothermia can set in within a short period, especially if there is a high wind chill overwhelming the fittest of swimmers. If sea conditions deteriorate, then the charity swim should be postponed or cancelled. If you see a person in difficulties do not attempt a rescue for which you are not trained. Make use of any nearby public rescue equipment such as a ringbuoy and in the event of an emergency call the emergency services on 112. No alcohol should be taken before the swim and remember to Get in, Get out and warm up.
Charity Swim guidelines:
People organising these swims on Christmas Day, St. Stephen's Day or New Year's Day should ensure that they provide comprehensive details of each event to the Irish Coast Guard and local Gardai.
Each event should have a Safety Officer appointed, who will advise those concerned on safety and have the ultimate responsibility for making decisions in relation to the swim being on or off on the day.
If the seas are rough and weather deteriorates, they should defer the event to a more suitable day without question - if in doubt do not take a chance on running the event.
Many participants will not have swum since the summer and the temperature of the water has now dropped considerably. It is a fallacy that alcohol will keep you warm when entering the water; in fact it has the reverse effect and could kill you. Irish Water Safety strongly recommends that no alcohol be taken either before the swim or after the swim and also remind people that they may be in breach of the drink driving laws when driving to or from the event.
Cold water can cause cold shock and hypothermia in minutes, because the temperature of the water at this time of year will be below 7° Celsius in Fresh Water and 12° Celsius in Seawater.
Ensure that you have safe access and egress with appropriate shallow shelving beaches, steps, slipway or ladders as appropriate. Elderly people should be mindful that steps leading into the water might be dangerous due to the increased growth of algae in wintertime. Organisers must ensure that they have had the access and egress cleaned in advance of the swim to avoid slips and falls.
Fancy dress outfits can seriously impair your ability to float - please do not wear when swimming.
Swimmers' remaining in the water for extended periods in a gesture of bravado is not acceptable and leads to hypothermia. Our message is "Get In, Get Out and Warm Up".
Thousands of people are at risk when taking walks by rivers, lakes and shorelines and even more are lulled into a false sense of security when visiting relatives living close to water hazards such as slurry pits, ponds, exposed drains and canals. Irish Water Safety has compiled this Christmas survival guide to staying safe around water over the holiday period.

LIFESAVING WATER SAFETY POINTS THIS CHRISTMAS:
Supervise children at all times, but especially if you are on holidays abroad this Christmas.
Never swim alone in a pool unprotected by lifeguards; in fact one should always ensure that there are lifeguards on duty within the pool area.
Do not engage in any water-based activities after the consumption of alcohol.
Alcohol should not be consumed before your water safety activity
Always wear a lifejacket when boating or participating in other aquatic sports.
In a Marine Emergency call 999 or 112 and ask for the Coast Guard.
3. Avoid cold shock and hypothermia on Christmas and New Year Charity Swims. 7. Stay away from the edge when fishing from rocks or on the banks of rivers, or lakes.

Flooding:
Avoid flooded areas as fast running water and submerged hazards pose a serious threat.
Rising waters, fast flowing currents and dangerous hidden hazards are all present with rising and receding flood waters. Move to higher ground immediately using alternative routes to avoid becoming trapped and respect the power of fast rising waters and the dangers of exposed drains and submerged objects. No driver or pedestrian should take a chance passing through flooded roadways. Parents should caution children that floodwaters hide the true depth and that manhole covers may be open and that small streams when swollen are very fast and deeper than normal. Knowing what to do when surprised by localised flash flooding will help avoid property damage, injury and drowning.
What should I do when I hear a Flood Warning?
Listen to the national and local radio for met eireann updates.
Check on neighbours particularly if they are elderly, infirmed or families with young children.
Move your vehicles to higher ground.
Move animal stock to higher ground.
Check your small craft to ensure they are well secured or moored.
Make sure you have warm clothes, food, drink, a torch and radio.
Block doorways and airbricks with sandbags or plastic bags filled with earth. Floodgate products will work effectively also.
Switch off gas and electricity supplies if flooding is imminent.
Check the time of High Water in the Newspaper, radio or online.

Personal Safety
Avoid flood waters at all times.
Carry a mobile phone at all times in case you need to call for help - call 112 or 999 in emergency.
Wear suitable protective clothing & a Lifejacket in on or around water.
Never try to swim through fast flowing water.
Never put your feet down if swept away.
Flooding on roads will be deeper at dips and around bridges.
Stay away from sea and flood defences.
When walking or driving, be aware of manhole covers and gratings that may have been moved due to the heavy flow of water.
Take care when using electric appliances in damp or flood conditions.
Remember that during the hours of darkness the dangers are multiplied.

Tides
As you walk shorelines, keep a close eye on new moon tidal advances and carry your mobile in case you are cut off.
On Christmas day we shall have a new moon. This is the first time this has happened since 1977 and it won't happen again until 2034, a new moon will increase the range of our tides causing higher and lower tides. This will expose large areas of beach and rocks which we don't see during neap tides. Many people enjoy exploring these new areas of beach and in particular enjoy picking shellfish to eat. The risk of becoming stranded as the tide advances can quickly leave people cut off from the shore which is why people should carry their mobile and call 112 if required. All those swimming, boating, surfing, or diving should be aware of stronger tidal streams around our coast over the Christmas weekend and swimmers need to be aware of risk rip currents will have on our beaches.
Ice
Should we experience icy conditions, there are dangers specific to frozen canals, rivers and lakes. Children are especially at risk as they are attracted to playing on ice. Constant supervision is the key to keeping children off the ice as there is no such thing as safe ice. Also at risk are individuals who attempt to rescue others fallen through ice. Ice-related drownings often occur when the rescuer gets into difficulty attempting to rescue another person or a family pet. Playing or fishing on the frozen edges of a river, lake or canal is perilous as ice can be quite thick in one area yet dangerously thin in others.
Ice Safety Tips to stay out of danger
Rescuing another person from ice can be dangerous. The safest way to perform a rescue is from shore. Use your Mobile.
Call for help at 999 or 112 and ask for the Emergency Services. Give your precise location, the number of people in difficulty and any conspicuous building or landmark nearby.
Check if you can reach the person using a Ringbuoy and rope, long pole, items of clothing or branch from shore - if so, lie down and extend the pole to the person.
If you cannot reach them then pass out something that will float e.g. a ringbuoy, empty water proof container e.g. oil, milk containers.
Instruct the casualty to keep still to maintain their heat and energy;
If you go onto ice, wear a PFD and carry a long pole or branch to test the ice in front of you. Bring something to reach or throw to the person (e.g. pole, weighted rope, line or tree branch).
When near the break, lie down to distribute your weight and slowly crawl toward the hole.
Remaining low, extend or throw your emergency rescue device (pole, rope, line or branch) to the person.
Have the person kick while you pull them out.
Move the person to a safe position on shore or where you are sure the ice is thick.
All casualties should be taken to hospital even if they appear to be unaffected by their ordeal as they will be suffering from hypothermia.
Never go out on ice alone and especially at night.

If you get into trouble on ice and you're by yourself
Call for help.
Resist the immediate urge to climb back out where you fell in. The ice is weak in this area.
Use the air trapped in your clothing to get into a floating position on your stomach.
Reach forward onto the broken ice without pushing down. Kick your legs to push your torso on to the ice.
When you are back on the ice, crawl on your stomach or roll away from the open area with your arms and legs spread out as far as possible to evenly distribute your body weight. Do not stand up! Look for shore and make sure you are going in the right direction.

Ice Rescue Tips:
Avoid going out on ice and discourage others from doing so.
Carry your mobile - Call for assistance from the emergency services.
Do not attempt a rescue by going onto ice, rather use any
Instruct the casualty to keep still thereby maintaining their heat and energy.
Try to find something close by that will extend your reach such as a ringbuoy, rope, pole, branch or items of clothing. Throw this to the casualty. Then make sure you are stable on the bank by lying down or getting someone to hold onto you and attempt to pull the casualty from the water.
If you cannot find something with which to perform a reach or throw rescue, try to find something that will float to throw or push out to them. This will help keep the casualty afloat until assistance arrives.
Throughout your rescue KEEP OFF THE ICE, and continue to reassure the casualty, keeping them talking until help arrives.
All casualties should be taken to hospital even if they appear to be unaffected by their ordeal as they will be suffering from hypothermia.

#fullmoon – The warm weather has brought many people out to enjoy the seaside and coastal walks, however the CEO of Irish Water Safety, John Leech is warning the public that there is a full moon tomorrow 2nd of July which is causing high spring tides which poses a higher risk of being washed in to the sea or being dragged out to sea by a rip current.

A danger foreseen can avoided...

Walkers should remain alert and stay well away from the edge of ordinarily familiar coastal walks due to the risk being washed in by large Atlantic swells. Those walking on our beaches and collecting sea shells should be alert to a fast advancing tide and of being stranded. Please carry your mobile phone and ideally in the company of others.

Anglers should be extremely vigilant, three having drowned so far this year. Atlantic swells present a clear danger to shoreline anglers and a substantial distance from the edge should be maintained at all times and always wear a lifejacket.

Swimmers be awareof rip currents, especially on surfing beaches, never swim against this narrow current of water flowing away from a beach. Instead, swim parallel to the shore, out of the narrow current, then swim back to shore at an angle. Details at http://www.iws.ie/beach/rip-current-safety.328.html

Divers completing drift dives need to carefully calculate the rate of drift and ensure that the dive boat maintains contact with their divers throughout the dive.

If an emergency develops don't delay - Call 112 and ask for Coast Guard.

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.
