Following the cancellation of Cork Week 300, ICRA has decided to combine the National Championships with this year’s WAVE regatta which will take place at Howth Yacht Club from September 11-13th.

The decision was taken by unanimous vote by all the cruiser-racer representative Board Members at a strongly attended ICRA (remote) meeting this week, with the full support and backing of the RCYC Cork Week team.

The decision took into account a number of factors, including the desire to ensure that the event took place if at all possible and was not cancelled again, the costs and implications of running a standalone event at this stage and the understanding of ensuring boats and crews had some possible opportunity to get up to speed before the event.

The meeting chaired by Commodore Richard Colwell included Cxema Pico, RIYC; David Cullen, HYC; John Leech, LDYC; Ric Morris, RIYC; Johanna Murphy, GISC & SCORA; Peter Ryan, NYC; Denis Byrne, RCYC; Liam Lynch, TBSC. Brian Raftery of SBSC was absent.

The ICRA Committee also say they wish 'to thank generous offers from other clubs to host the regatta on alternate dates'.

Commodore Richard Colwell commented “The ICRA Committee is saddened that the efforts of Cork Week cannot come to fruition so we have considered several alternative options for our annual ICRA National Championships. It was agreed that it would be prudent in the current environment, to delay the important National Championship regatta until as late as possible to try and ensure it goes ahead this year, so we have taken up the offer from Howth Yacht Club to combine the event with the WAVE regatta in September.”

"it would be prudent in the current environment, to delay the important National Championship regatta until as late as possible"

WAVE Chairman, Brian Turvey added “Our team in Howth is delighted to be able to lend support to ICRA for their 2020 Championships. Wave Regatta provides a relatively simple integration for the ICRA Nationals with much of the fleet already intending to compete and at a time of the year which suits many classes for their annual championships, not least that we are hopeful that the pandemic will have abated by then.”

Due to the uncertainty of which events will proceed, it has also been decided to cancel the original Boat of the Year schedule of races and keep under review.

Once we get clarity on what events will be proceeding, we will reissue a revised Notice of Race, ICRA spokesman Dave Cullen said.

#RecordWave - Nineteen metres is the height of what’s being called the world’s largest wave, recorded recently off the North West Coast of Ireland.

Independent.ie reports on the record-breaking swell detected by a weather buoy in the North Atlantic between Ireland and Iceland, following what the World Meteorological Organization’s (WMO) Commission for Climatology described as a “very strong” cold front that passed through at more than 80km per hour.

WMO Assistant Secretary-General Wenjian Zhang said: ”This is the first time we have ever measured a wave of 19 metres. It is a remarkable record.”

The new measurement beats the previous record of 18.275 metres recorded in the North Atlantic nine years ago.

But while the news is causing gasps around the internet, for some it only confirms what’s long been known — that Ireland is on the doorstep of a big wave paradise.

Indeed, Ireland’s North West is no stranger to monster swells, with the giant surf offshore from Mullaghmore in Co Sligo a well-kept secret among the big wave surfing fraternity.

The dangers of winter storms and the risk posed by freak waves are illustrated on the beach of Porsguen near to Portsall in Western France when a retired couple are swept away this month.

It is understood the couple survived the ordeal and rescued by coastal walkers.

The edge of the sea seems to be far enough away for the three people in this clip to be safe – but they are soon to learn that it isn’t.

A large wave crashed onto shore, knocking a pensioner to the floor. First his wife tries to save him before she too loses her footing and ends up being washed out.

The video was shot on the coast of France near Porsguen and uploaded onto YouTube by Olivier Lou who thanked locals Denise and Herve for giving them dry clothes.

#castletownbere – The Department of Transport, Tourism and Sport has been advised that a wave measuring device has been installed on the seabed, adjacent to the Walter Scott Rock, at co-ordinates Latitude 51° 38' 33.6"N, Longitude 009° 54' 20.4"W. A yellow floating marker buoy with a special mark beacon has been installed to indicate the location of the device.

The wave study is being carried out by the Marine Engineering Division of the Department of Agriculture, Food & the Marine. The study is expected to be on-going until late March 2015, weather permitting.

For safety reasons, mariners are requested to keep a sharp lookout and to proceed slowly and with extreme caution in the vicinity of the Walter Scott Rock.

For safety reasons, fishermen are requested to avoid dredging at the co-ordinates mentioned above. Fisherman should take great care when dredging near this location and keep a wide berth from the device which is located on the seabed.

#wave – A new maximum wave height measuring nearly 80–feet (23 metres) has been recorded in weekend storms off the coast of Ireland.

Monster waves the height of five double deck buses occurred during last weekend's ferocious storms off the coast of Donegal, the worst for 30 years, according to Donegal news sources.

The M4 weather buoy, located off the Northwest coast, recorded a new maximum individual wave height of 23.4 metres at 15.00 on Sunday 26th January 2014 during the weekend storm that prompted an orange alert by the Coast Guard.

The new wave measurement easily surpasses the previous record of 20.4 metres at the same location in December 2011, according to Met Eireann.

The M4 buoy is one of a new generation of weather buoys with the ability to measure maximum wave height as well as the more usual Significant Wave Height.

The Significant Wave Height is defined as the average height of the highest one-third of the waves and that is what our forecasts of wave height refer to.

In general, the highest wave of all will be about twice the Significant Wave Height.

There was also a record for maximum significant wave height for the M4 buoy of 15.3m at the same time, with the previous record being 14.7m. The all-time record for Significant Wave Height still rests with the M6 buoy of 17.2m.

#SURFING - British surfer Jayce Robinson wasn't about to let the largest wave ever recorded off Ireland's shores go by without giving it a shot.

And as Sky News Online reports, he was captured doing exactly that on Tuesday afternoon.

The Cornish surfing pro told the website: "It was definitely the biggest barrell I've ever surfed.

"I was a little nervous but I didn't have time to think about it - it's almost like a car crash, you don't know what's happening."

Robinson rode the giant wave for 20 seconds before the lip crashed down and knocked him off his board.

His surfing partner Lyndon Wake, who towed him to the swell at Mullaghmore Head, said: "It's always a worst case scenario when your tow partner wipes out. Lucky he managed to come out the other side OK."

As previously reported on Afloat.ie, storm force winds off the coast of Donegal produced monster rollers of over 20 metres (over 60 feet) in height detected in Donegal Bay.

Mullaghmore Head will once again welcome the world's top big wave surfers for the second annual Tow-In Surf Session in the New Year.

#WAVE – The biggest ever wave in Irish waters was recorded yesterday when storm force winds off the Coast of Donegal produced monster rollers of over 20 metres (over 60 feet) in height off the Northwest tip of Ireland. At least two giant waves put meterologists on alert yesterday prompting the Coastguard to issue a weather warning.

The 20.4 metre wave was detected in Donegal Bay by the M4 weather buoy, according to Met Eireann. The wave was recorded at 2pm yesterday.  (Tuesday 13th December 2011),

Meteorologists said sea conditions, about 60 miles out to sea, were the most serious they had ever experienced. The Irish Coastguard said they had recorded winds of up to 140km per hour off the north-western coast yesterday and issued a warning.

The M4 weather buoy is located 75km north of Belmullet on the north west coast of Ireland. The M4 buoy forms part of the Irish Weather Buoy Network which began in 2000 and is funded by the Department of Transport, Tourism and Sport and run by the Marine Institute in collaboration with Met Eireann and the UKMO.

"This is the largest wave measured on the Weather buoy network to date. However, these recordings are a result of the next generation buoy which was deployed last year. Historically, only the significant wave height could be measured by the older buoys, where heights of between 10 and 13 meters were typically recorded around the coast during winter. The next generation buoys allow us to record and transmit both significant wave height and maximum wave heights as part of our hourly observations," explains Sheena Fennell, oceanographer with the Marine Institute.

Over the last number of years the network has been going through a transitional phase replacing the older models with next generation buoys supplied by Fugro Oceanor. The combination of high quality real time measurements coming from the offshore buoys and coastal systems, coupled with the mathematical forecasting models, is extending the well proven ability of scientists and engineers to accurately forecast the atmospheric conditions and sea state of the ocean.

"With the development in technology we are now able to record maximum wave heights which the older style buoys couldn't do. This parameter will form an important part of forecasting as we move forward." Sheena Fennell further said.

Met Eireann say the stormy conditions will gradually ease off tonight, but then frost and icy patches will develop. However it will remain very windy for a time early tonight, with severe southwest to west gales.

Spectacular photographs taken from the shore by Lifeboat Operations Manager John Brittain during Clifden RNLI's special surf training recently on Dunloughan beach show the type of conditions that volunteer lifeboat crew train in for the life-saving charity. The shots capture the inshore lifeboat crewmembers climbing a wave and exercising in some choppy conditions.

John organised the training in response to the increased popularity of the area with surfers.  RNLI Divisional Assessor Trainer Helena Duggan travelled to the lifeboat station to put 18 volunteer lifeboat crew through their paces and train them in handling the lifeboat in surf and responding to potential callouts from leisure marine enthusiasts.

Training is a core part of volunteering with the RNLI and each crewmember in Clifden trains once a fortnight on the stations two inshore lifeboats.

Commenting on the exercise John said, "I took my camera down to photograph the exercise and was really pleased with the results.  It is great to be able to show the public what our lifeboat volunteers go through to ensure they are fit and trained to go to sea. We had a fantastic turnout on the day and the lifeboat crew learned about boat handling in surf conditions. We are delighted so many people are visiting the area for leisure marine activities."

A US renewable energy company is proposing to meet the Government’s target of generating 500 megawatts of electricity from ocean energy systems by 2020, holding out the possibility of generating tens of thousands of jobs in Ireland. Frank McDonald's story in the Irish Times this morning is here.

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.
