A mini boat that was swept from Newfoundland’s Grand Banks to Achill Island in Storm Erik is due to be relaunched off Ireland sometime in the next few weeks.

The Newfoundland students who first helped to launch the 1.8m (6ft) Raven Kaster are working with Achill island pupils on preparing it for another sea voyage.

This time, it will also collect ocean climate data and may end up off the Iberian coast or up in Scandinavia, depending on where it is launched.

“The way ocean currents work, we don’t know where it will land, and a lot depends on where we launch it again,” Thomas Sheppard, a teacher at Frank Roberts Junior High in Newfoundland, explained.

“The only way it would return to North America is if it is launched off the coast of Africa,” he said.

Canadian students Stephanie Evans and Kaitlyn Grandy, who led the project back in 2018 while at school, recalled that they weren’t sure if they would ever see their little craft again when they were reunited with it for the first time this past weekend in Galway.

“We had the GPS track on it after it was launched by a Maersk ship for us on the Grand Banks in November 2018, and it looked like it was going to bypass Ireland and head south,” Evans recalled.

“Then we saw it heading for a little island off Ireland, and we just hoped there were people there! “ she said.

Raven Kaster, as the craft is named, was washed up on Dookinella Beach on Achill Island after 102 days at sea, and was found there in February 2019 by local fisherman Darren Kilbane.

Evans and Grandy have travelled to Ireland with Sheppard, their teacher, to meet pupils at Coláiste Pobail Acla secondary school and their deputy principal, Karen Lavelle, who are working on the re-launch project.

One of their first stops was at Galway Atlantaquaria in Salthill to view the Raven Kaster. They will also discuss the re-launch logistics with the Marine Institute in Galway this coming week.

Neither Evans nor Grandy had heard of Achill Island when the GPS track indicated it had landed there.

The 1.8m (six ft) boat was purchased through Educational Passages, a non-profit company that runs a mini boat programme.

“Most of them are GPS based, with solar power for the GPS and sail, along with a cargo hold for notes which the students can leave inside,” Sheppard explained.

“Now it is going to be fitted with software which will allow for measuring air temperature, water temperature, orientation, and it will have a camera – stuff we didn’t have available to us when we launched the boat back in 2018,” Sheppard said.

“It wasn’t in bad condition when Darren Kilbane found it, and his daughter Ria is one of the transition year students who has been working on it,” Lavelle explained.

“We hope the Marine Institute’s research ship Celtic Voyager will take it out to the Porcupine before the winter storm season. Depending on the weather and ocean currents, it could go up or down the Atlantic,” she said.

Captain Jacek Berenek of the container ship, ‘Independent Horizon,’ on its regular monthly call to the Port of Cork’s Deepwater Berth at Ringaskiddy, explained to the pupils of Barryroe National School from West Cork where he would launch their mini-boat into the Atlantic Ocean. With his Chief Officer, Naumowicz Jaroslaw, he showed the boys and girls from Barryroe a chart of the ocean area, explaining how winds and tides would carry their boat, ‘Realt na Mara,’ back towards the American coastline where it had originally been made by the sixth-grade students of Morristown Beard School in Boston.

“It is useful for the school to learn more about the sea. You are Irish, living close to the sea, you should celebrate that you are living in such a place,” he told them. “We will launch your boat as we get close to the coast of America on our voyage. This is a good project for young people to learn about the tides, the currents, about the sea.”

This was at Ringaskiddy deepwater port in Cork Harbour, where the ‘Independent Horizon’ was loading containers. She calls every four weeks on a run that connects Cork and the South of Ireland with Wilmington on the Delaware River and Chester City in Delaware County, Pennsylvania. She is a supporter of Educational Passages, a non-profit organisation based in Maine, USA, which connects schools around the world to the oceans and each other. Its approach is a "21st Century version” of the old-style ‘Message in a Bottle’ across the oceans, using modern technology. The mini boats are five feet long, under two metres, uncrewed, GPS-tracked, student-built little vessels. They have a satellite transmitter, solar-powered, enabling the boats to be tracked as they sail the oceans.

“Our Miniboat Programme empowers students to become citizen scientists and global ocean stewards,” the organisation says. “They enable connection with the local school and community where a boat lands and advance learning about cultures around the world, tracking their mini boats while learning about ocean currents, weather, technology and much more about the oceans.”

The ‘Crimson Current’ was the name of the mini boat from Morristown Beard School launched by ship in the North Atlantic in April of last year. Tracking was lost as it approached the Irish coast. Rory Jackson from Tragumna, who runs West Cork Ocean Tours and the Oceans Plastics Project for schools, was contacted. Helped by local fisherman Billy McCarthy, gauging currents and tides, they figured Barry’s Cove on the Seven Heads Peninsula, southeast of Clonakilty, would be a likely arrival point. On July 5 last year, they were proved correct. Using a kayak to enter a cave, Billy McCarthy found the boat. “It was at the back of the cave, small, not that easy to see, but afloat and I recovered it.”

Rory Jackson took it to Barryroe National School. When opened,’ Crimson Current’ contained various items, including a baseball, an Abraham Lincoln coffee mug, a Morristown Beard baseball cap and a USA jersey. Contact was made from 5th and 6th Class with the sixth formers in Boston from the boardroom of Barryroe Co-op. That developed into the West Cork students refurbishing and re-naming the little vessel - ‘Realt na Mara.’

One of the Barryroe pupils, Scarlet O’Mahony, told me that the pupils made a new sail, designed, symbolising County Cork, the coastal and countryside of Ireland. “We have wildlife on it, showing that Ireland is full of Nature. We have included the history of Ireland and that we are an island, shown our national sport, and even put in a tin whistle, the instrument we play in our school. Our boat is signed by both 5th and 6th classes, and the hull has horseshoes, tea bags, a hurley and a signed Barryroe Jersey, amongst lots of other items that we have put into it. We will be following the mini boats GPS tracker with great interest over the weeks ahead,”

“Whether you’re on the coast or land-locked, anyone can take part as the programme creates an ocean classroom,” the Educational Passages organisers say. “Our Miniboat Programme offers an extraordinary way for people of all ages to learn crucial skills, discover maritime careers and build connections that will last a lifetime. It engages participants in collaborative learning through international cultural experiences and increases the understanding of the value of water on our planet as a shared resource through ocean literacy. Over the last decade, new boat designs, partnerships and ambitions have expanded its scope. People of all ages and across dozens of countries track the little boats. Clubs, schools, libraries, individuals and foundations have joined what is now an international educational community connecting and educating students by building, launching, and recovering the boats, spanning the globe; it’s an ocean of educational opportunities.”

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.
