A harbour near Melbourne in Australia is probing the potential of its natural tides to develop a new kind of renewable energy hub.

As the Bellarine Times reports, Queenscliff Harbour has partnered with the non-profit Southern Ocean Environmental Link and tidal turbine maker Altum Green Energy to install a device near the harbour’s marina.

The area of Port Phillip Heads, also known as The Rip, is at the narrow entrance to the large bay on which Melbourne lies to the northeast.

Its large tidal flows make it a treacherous stretch for boating and shipping, but a potentially rich one for generating power from the sea.

The joint project is currently collecting measurements at the location to determine its potential and best positioning for the Altum turbine, which is designed to operate in slow-flowing waters such as at ports and bridges, rivers, canals and islands.

Exploring development of the “next generation” tidal energy technology is the theme of a new project initiated by NUI Galway (NUIG).

The university says the tidal energy project is part of its “Global Challenges” programme, a targeted research initiative to tackle six of the globe’s most pressing issues.

The project will focus on new technology and tidal turbine blades, site modelling, and the assessment of climate change impact and extreme events on same.

It will include an economic appraisal of tidal energy and the investigation of societal attitudes; and stakeholder engagement to better understand the needs and concerns of tidal energy developers, local authorities and the coastal communities.

It will also research systems to assess the interactions of tidal energy infrastructure with wildlife.

Five PhD researchers will be recruited for the project.

Globally, the tidal energy resource is estimated at more than 1200 terawatts per annum - a unit of power equal to one trillion watts.

The world uses 17.7 terawatts a year, according to the NUIG researchers.

The project will be led by Prof Jamie Goggins, professor of civil engineering, MaREI Centre, Ryan Institute and School of Engineering at NUIG.

He said the project “will engage with multiple stakeholders - including the people living in the coastal communities - to unlock the potential benefits for them in our drive to decarbonise the economy”.

“The just transition is crucial in the work towards decarbonisation. So too is the importance placed on biodiversity and how we enhance the health and resilience of our ocean and coastal communities,”he said.

“ Our aim in the tidal energy project is to create a blueprint to simultaneously achieve these ambitions,”Prof Goggins added.

The NUI Galway Global Challenges fund is part of the university’s new Research and Innovation Strategy 2021-26.

It has six areas of focus - antimicrobial resistance, decarbonisation, democracy, food security, human-centred data, and ocean and coastal health.

#SeaPower - Northern Ireland is well placed to capitalise on the growing trend towards renewable energy thanks to its unique tidal resources, according to a leading researcher in the field.

Dr Carwyn Frost of Queen’s University Belfast tells Emily McDaid of local tech incubator Catalyst Inc that the Narrows between Strangford Lough and the Irish Sea have the perfect conditions to harness the power of the sea’s tides — in shallow waters away from ocean swell, and more accessible than similar sites in the far north of Scotland.

The area was previously home to the world’s first tidal power station in the form of the SeaGen turbine, and has since been a test site for new projects such as the PowerKite developing the next generation of tidal energy devices.

#SeaPower - A prototype tidal energy turbine project in the Shannon Estuary has received almost €100,000 in funding for further development, as the Limerick Post reports.

GKinetic has been testing a scale prototype of its new hydrokinetic turbine for the last year, at a purpose-built facility in Limerick Docks set up in tandem with the Shannon Foynes Port Company.

The new funding of €99,562 from the Sustainable Energy Authority of Ireland’s (SEAI) Prototype Development Fund will support testing on an improved prototype from August for a six-week period, as the company ramps up plans to scale up the design to a 250kW tidal device.

GKinetic’s technology is already being commercialised by fellow Co Limerick company DesignPro, who secured funding earlier this year under the Horizon 2020 project to test its own river energy devices at scale.

James Ives, CEO at tidal energy company OpenHydro will speaking tomorrow at the Ocean Energy Europe Conference being held this week in Croke Park in Dublin. Ives will tell how the Irish marine renewable firm is to be the global leader in tidal solutions, profitably delivering economic marine renewable energy.

The Department of Communications says that €4.5m. will be allocated to ocean energy research in Ireland under Budget provisions next year. Total allocation for energy efficiency and renewable energy onshore and offshore next year is €68m. €9 million is being provided for geoscience initiatives including the INFOMAR and TELLUS programmes, which will support expanded geoscience research in Ireland’s offshore and onshore.

OpenHydro, a DCNS company, based in Ireland, is a technology business that designs and manufactures marine turbines to generate renewable energy from tidal streams. The company's vision is to deploy farms of tidal turbines under the world's oceans - silently and invisibly generating electricity at no cost to the environment. OpenHydro's technology enables the ocean's immense energy to be harnessed for the benefit of all. The electricity produced is completely renewable since it relies on tides that are created by the gravitational effect of the sun and moon. Through this innovative technology, OpenHydro will extract energy from the oceans in an economically viable and environmentally sensitive manner.

OpenHydro has developed the innovative Open-Centre Turbine technology which is a shrouded, horizontal-axis turbine. Simplicity is the key advantage of this technology: manufactured from a small number of components and with only one single moving part (the rotor). There is no need for oils, seals or a gearbox and this not only reduces the requirement for maintenance but ensures reliable performance in the harsh environment that is the World’s oceans. The turbines, each supported on a subsea structure, are placed directly onto the seabed, deep enough so as not to pose a hazard to shipping traffic overhead and the standard OpenHydro product has a diameter of 16m and is rated at 2MW. OpenHydro has also developed a patented method to install the Open-Centre Turbines, allowing all deployments to be completed in a single tidal cycle; less than 6 hours.

OpenHydro is at the fore-front of the tidal industry, with nearly one gigawatt of development in progress across multiple sites in Europe and North America.

#SeaPower - What's been described as the world's largest planned tidal energy scheme has been given the green light by its financiers, with construction set to begin off the northern Scottish coast in the new year, as The Guardian reports.

Previously detailed last month on Afloat.ie, the MeyGen project – comprising 269 turbines on the seabed off Caithness in the far north of mainland Scotland – will see onshore construction get under way next month after developers Atlantis Resources satisfied the conditions to draw down funds from The Crown Estate of Scottish Enterprise.

MeyGen aims to harness the strong currents at the Ness of Quoys in Pentland Firth to generate energy at levels "on a part with wind turbines" but hidden from view beneath the waves - with the first power from the sea to be delivered to Britain's national grid by 2016.

#PowerFromTheSea - The next big renewable energy turbine farm could be underwater off the coast of Scotland, as MailOnline reports.

Scottish firm MayGen has big plans to install a £51 million (€65.2 million) underwater turbine project to harness the powerful currents of their country's coastal waters.

This new project, earmarked for Pentland Firth at Caithness in the far north of mainland Scotland, follows separate plans to install the world's largest tidal power facility in the Sound of Islay.

MayGen - which has just won an award for its parent company Atlantis Resources for its "significant contribution" to the marine renewables industry – says its state-of-the-art technology is "on a par with wind turbines" in terms of productivity, but would be hidden from the view of those who find the larger land-based wind farms unsightly.

The Pentland Firth project will be the new design's proving ground, with hopes that it will generate power for nearly half a million homes upon completion in 2020.

#POWER FROM THE SEA - Marine-based renewable energy projects could be introduced without a damaging impact on marine wildlife, according to a new briefing paper from Friends of the Earth.

Business Green reports on the paper from the environmental campaign group, written by marine ecologist Martin Attrill of Plymouth University's Marine Institute, which draws together research on the biodiversity impact of offshore wave energy, tidal energy and wind power schemes.

Attrill found that the deployment of sea energy arrays could ultimately benefit many marine species by reducing the effects of fishing activity, and even acting as reefs to attract new sea life.

He cites the example of a grey seal colony in Strangford Lough that has steered clear of a nearby tidal turbine over the three years of its operation in the lough.

However, Business Green says the report makes clear that the deployment of such projects "must be done sensitively", noting that any negative impact on biodiversity "would be significantly lower than the damage done to marine wildlife by rising sea levels caused by climate change".

#POWER FROM THE SEA - A €9 million Europe-wide wave energy trial programme is one of the key elements of a new Government programme designed to transform Ireland as a maritime nation.

According to The Irish Times, University College Cork's Hydraulics and Maritime Research Centre will run testing of wave energy, tidal energy and offshore wind energy devices across a network of sites in 12 European countries participating in the new marine renewables infrastructure network Marinet.

Irish test sites in the network include the national ocean test facility in Cork and centres operated by the Sustainable Energy Authority of Ireland (SEAI) at Galway Bay and Belmullet.

The UCC centre also forms part of the new Irish Maritime and Energy Resource Cluster (IMERC), launched last Friday by Taoiseach Enda Kenny.

The cluster comprises UCC, the Irish Naval Service, Cork Institute of Technology and the National Maritime College of Ireland with the initial aim of creating 70 new research jobs by 2014 in the areas of wave energy, green shipping and sustainability of ocean resources.

IMERC director Dr Val Cummins said: “The aim of IMERC is to promote Ireland as a world-renowned research and development location that will unlock Ireland’s maritime and energy potential."

Dublin Bay 21s

An exciting new project to breathe life into six defunct 120-year-old Irish yachts that happen to be the oldest intact one-design keelboat class in the world has captured the imagination of sailors at Ireland's biggest sailing centre. The birthplace of the original Dublin Bay 21 class is getting ready to welcome home the six restored craft after 40 years thanks to an ambitious boat building project was completed on the Shannon Estuary that saved them from completely rotting away.

Dublin Bay 21 FAQs

The Dublin Bay 21 is a vintage one-design wooden yacht designed for sailing in Dublin Bay.

Seven were built between 1903 and 1906.

As of 2020, the yachts are 117 years old.

Alfred Mylne designed the seven yachts.

The total voting population in the Republic's inhabited islands is just over 2,600 people, according to the Department of Housing.

Dublin Bay Sailing Club (DBSC) commissioned the boat to encourage inexpensive one-design racing to recognise the success of the Water Wag one-design dinghy of 1887 and the Colleen keelboat class of 1897.

Estelle built by Hollwey, 1903; Garavogue built by Kelly, 1903; Innisfallen built by Hollwey, 1903.; Maureen built by Hollwey, 1903.; Oola built by Kelly, 1905; Naneen built by Clancy, 1905.

Overall length- 32'-6', Beam- 7'-6", Keel lead- 2 tons Sail area - 600sq.ft

The first race took place on 19 June 1903 in Dublin Bay.

They may be the oldest intact class of racing keelboat yacht in the world. Sailing together in a fleet, they are one of the loveliest sights to be seen on any sailing waters in the world, according to many Dublin Bay aficionados.

In 1964, some of the owners thought that the boats were outdated, and needed a new breath of fresh air. After extensive discussions between all the owners, the gaff rig and timber mast was abandoned in favour of a more fashionable Bermudan rig with an aluminium mast. Unfortunately, this rig put previously unseen loads on the hulls, resulting in some permanent damage.

The fleet was taken out of the water in 1986 after Hurricane Charlie ruined active Dublin Bay 21 fleet racing in August of that year. Two 21s sank in the storm, suffering the same fate as their sister ship Estelle four years earlier. The class then became defunct. In 1988, master shipwright Jack Tyrrell of Arklow inspected the fleet and considered the state of the hulls as vulnerable, describing them as 'still restorable even if some would need a virtual rebuild'. The fleet then lay rotting in a farmyard in Arklow until 2019 and the pioneering project of Dun Laoghaire sailors Fionan De Barra and Hal Sisk who decided to bring them back to their former glory.

Hurricane Charlie finally ruined active Dublin Bay 21 fleet racing in August 1986. Two 21s sank in the storm, suffering the same fate as a sister ship four years earlier; Estelle sank twice, once on her moorings and once in a near-tragic downwind capsize. Despite their collective salvage from the sea bed, the class decided the ancient boats should not be allowed suffer anymore. To avoid further deterioration and risk to the rare craft all seven 21s were put into storage in 1989 under the direction of the naval architect Jack Tyrrell at his yard in Arklow.

While two of the fleet, Garavogue and Geraldine sailed to their current home, the other five, in various states of disrepair, were carried the 50-odd miles to Arklow by road.

To revive the legendary Dublin Bay 21 class, the famous Mylne design of 1902-03. Hal Sisk and Fionan de Barra are developing ideas to retain the class's spirit while making the boats more appropriate to today's needs in Dun Laoghaire harbour, with its many other rival sailing attractions. The Dublin Bay 21-foot class's fate represents far more than the loss of a single class; it is bad news for the Bay's yachting heritage at large. Although Dún Laoghaire turned a blind eye to the plight of the oldest intact one-design keelboat fleet in the world for 30 years or more they are now fully restored.

The Dublin Bay 21 Restoration team includes Steve Morris, James Madigan, Hal Sisk, Fionan de Barra, Fintan Ryan and Dan Mill.

Retaining the pure Mylne-designed hull was essential, but the project has new laminated cold-moulded hulls which are being built inverted but will, when finished and upright, be fitted on the original ballast keels, thereby maintaining the boat’s continuity of existence, the presence of the true spirit of the ship.

It will be a gunter-rigged sloop. It was decided a simpler yet clearly vintage rig was needed for the time-constrained sailors of the 21st Century. So, far from bringing the original and almost-mythical gaff cutter rig with jackyard topsail back to life above a traditionally-constructed hull, the project is content to have an attractive gunter-rigged sloop – “American gaff” some would call it.

The first DB 21 to get the treatment was Naneen, originally built in 1905 by Clancy of Dun Laoghaire for T. Cosby Burrowes, a serial boat owner from Cavan.

On Dublin Bay. Dublin Bay Sailing Club granted a racing start for 2020 Tuesday evening racing starting in 2020, but it was deferred due to COVID-19.
Initially, two Dublin Bay 21s will race then three as the boat building project based in Kilrush on the Shannon Estuary completes the six-boat project.
The restored boats will be welcomed back to the Bay in a special DBSC gun salute from committee boat Mac Lir at the start of the season.
In a recollection for Afloat, well known Dun Laoghaire one-design sailor Roger Bannon said: "They were complete bitches of boats to sail, over-canvassed and fundamentally badly balanced. Their construction and design was also seriously flawed which meant that they constantly leaked and required endless expensive maintenance. They suffered from unbelievable lee helm which led to regular swamping's and indeed several sinkings.
