New predictive technology being developed in Estonia could help prevent the spread of pollution from shipwrecks.

Estonia’s public broadcaster ERR News reports on the monitoring system created by marine scientists at Tallinn University of Technology (TalTech) that may forecast where fuel will spread in the water from a hazardous wreck site.

Estonia’s coastline on the Gulf of Finland, Gulf of Riga and Baltic Sea has a large number of decades-old shipwrecks which are increasingly prone to fuel leaks as they age.

So far the results are promising, with TalTech’s predictive computer models — using current and wave data from Estonian waters — matching real-world data collected from smart buoys placed at a number of coastal sites.

Surveyors for the INFOMAR seabed mapping programme have reported the detection of two obstructions on the Atlantic floor some 30 nautical miles west of Co Galway.

Marine Institute research operations manager Aodán Fitzgerald told RTÉ News that these obstructions are likely shipwrecks.

“There are thousands of these in Irish waters,” he said. “However as these are fishing areas, we issued a notice to advise fishermen with towed fishing gear to avoid the areas.”

As previously reported on Afloat.ie, a series of seabed mapping surveys was launched in February this year, with the RV Tom Crean recruited to carry out operations west of west of Kerry, Clare and Galway outside the 30nm limit.

The State’s latest marine research vessel found one of the objects around 80km west of the Aran Islands in Galway Bay, and the other 70km west of Loop Head in Co Clare.

Coordinates for the obstructions are included in Marine Notice No 64 of 2023, attached below.

Shipwrecks with no known owner will become State property under new legislation which Minister of State for Heritage Malcolm Noonan is proposing.

The legislation also proposes that commercial salvage law does not apply to historic wrecks.

The Monuments and Archaeological Bill intends to revise and replace the National Monuments Acts 1930 to 2014.

It was presented by Noonan on Thursday evening to the Joint Committee on Housing, Local Government and Heritage.

The Department of Housing said the proposed Bill seeks to introduce new measures to protect archaeological structures and sites.

It will include the establishment of a single register of monuments, a statutory reporting scheme for newly discovered monuments and provisions to prevent the illicit import and possession of stolen cultural property.

“Another innovative element of the proposed Bill is to incorporate historic wrecks and underwater cultural archaeological objects into the new scheme for monument protection,” it said.

“The proposed Bill will also enable the State to ratify and give effect to several important international conventions relating to the protection of cultural heritage,” the department said.

Multiple amendments to the National Monuments Act 1930, along with multiple transfers of functions, have resulted in “fragmented legislation which is far from easily accessible and comprehensible”, it explained.

“The proposed legislation aims to address a range of structural issues, simplify terminology, as well as provide a single accessible piece of legislation,” the department said.

“This proposed Bill will modernise existing legislation protecting monuments and archaeology – some of this legislation dates back to the 19th century,” Noonan said.

“ If enacted, this legislation will substantially strengthen protection of archaeological heritage for the enjoyment of future generations and also represent major progress on the protection of our built heritage,” he said.

He referred to the department’s recent publication of a Vernacular Strategy to protect traditional buildings.

He said there were plans to launch “Heritage Ireland 2030” in the coming weeks, as in a “new national heritage plan to provide a vision and backdrop to realise our full set of ambitions for Ireland’s built, natural and archaeological heritage”.

The Department of Transport advises that a survey will take place at several offshore reefs and sandbanks off the North West Coast from next Friday 23 April to Tuesday 4 May.

Survey works with marine robots in support of the EU Horizon 2020 research and innovation programme will take place within a three-nautical-mile radius of six shipwrecks, the coordinates of which are included in Marine Notice No 24 of 2021 which can be downloaded below.

The survey will be conducted from the RV Celtic Explorer (callsign EIGB) which will conduct acoustic surveying during the night using its hull mounted multibeam, with remotely operated vehicle (ROV) sampling during daylight hours.

In addition, the vessel will be used as a platform to deploy a range of unmanned underwater vehicles (UUVs) and a series of six small (1.2m3) pyramidal landers, referred to as baited remote underwater video (BRUV).

At all times, the RV Celtic Explorer will display appropriate lights and signals.

Dublin Bay Old Gaffers’ Association invites all to join their next Zoom session on Shipwrecks Around Dublin Bay, which will be given by Cormac Lowth on Thursday 25th February at 20.00hrs.

Following on from his extremely popular talk on the loss of the Palme and the tragic demise of the Kingstown Lifeboat in 1895, the renowned maritime archaeologist and historian Cormac Lowth will talk on “Shipwrecks Around Dublin Bay.” Based on historical research, hydrographic surveys, underwater photography and data from his own diving expeditions, Cormac will reveal the stories behind many of the shipwrecks hidden under the waves of Dublin Bay and the nearby coast.

Only partially protected by the offshore shoals of the Bennet and Kish Banks, Dublin Bay has proved to be a graveyard for many ships. Closer inshore the Burford and Rosbeg Banks lie in wait for the unwary.

The sinking of the Queen Victoria

Cormac will describe the sinking of the Queen Victoria in 1853, the Tayleur on Lambay in 1854, the Vanguard in 1875, the Palme in 1895 and the Bolivar in 1947 to name but a few. If you are interested in Dublin Bay and marine archaeology you will not want to miss this talk.

Please be early to be sure of getting a good seat!

“Substantial progress” is being made in the recovery of gold bullion from a ship wrecked off Donegal nearly 80 years ago, as RTÉ News reports.

Atlantic Subsea Ventures is involved in the salvage operation at the Empress of Britain, a luxury ocean liner that was requisitioned for the war effort in 1939 and targeted by the Nazis the following year.

A number of such vessels are believed to lie in the depts around Ireland, with one in recent years — the SS Gairsoppa off Galway — giving up a record 48 tonnes of silver bullion seven years ago.

The Empress of Britain, which is believed to hold as much as €500 million in gold bullion, was found in 1995 but its location in deep waters precluded any salvage expedition, until now — thanks to remote-operated technology used in the oil and gas industry.

What’s proving a bigger stumbling block for the salvage company, it says, is Ireland’s 7.5% levy on recovered cargo which must also be held for a year and a day before it can be moved on.

Shipwrecks off the Irish coast are acting as artificial reefs for corals usually found much deeper in the Atlantic.

That’s according to NUI Galway ocean scientist Anthony Grehan, who told the Irish Examiner about his recent surprising find at the wreck of a cargo vessel 160 metres below the surface.

Using the new submersible robot Étáin from the University of Limerick, Grehan and a team on the RV Celtic Explorer found examples of the stony coral species lophelia pertusa, which usually found at depths of 500 metres or more.

And the new discovery suggests that such wrecks may provide the necessary stability for deep-water corals to thrive in shallower waters.

#Shipwrecks - Heritage Minister Josepha Madigan yesterday (Wednesday 25 April) announced the launch of a new website with an interactive map of the thousands of historic shipwrecks in Irish waters.

The Wreck Viewer has been developed to facilitate free and easy access to the Wreck Inventory of Ireland Database compiled by the National Monuments Service of the Department of Culture, Heritage and the Gaeltacht. 

The database holds information on over 18,000 known and likely wreck sites both off the Irish coast and in Ireland’s inland waterways

These wrecks span the entirety of maritime travel around and within the island, from prehistoric logboats to medieval trading vessels, warships and ocean liners

Detailed are exact locations for approximately 4,000 of the recorded wrecks. The map also provides summary information on individual wrecks and their history, voyage, cargo, passengers and, if known, the circumstances of their loss. 

Information on the 14,000 wrecks in the database for which locations have yet to be fully confirmed can also be downloaded. Further details of these wrecks will be added to the database as they become available.

The Wreck Viewer complements the department’s Historic Environment Viewer, which provides information on archaeological sites across the country from the Sites and Monuments Record compiled under the National Monuments Acts and from the National Inventory of Architectural Heritage.

Speaking on the new Wreck Viewer yesterday, Minister Madigan said: “Of particular interest, in this decade of centenaries, are the stories of those wrecks from the First World War. 

“Over 1,000 ships were lost off the coast of Ireland during that conflict, in effect bringing the Western Front to our shoreline and alerting the Irish people to both the grim realities of war and the scale of the tragic loss of life that took place on land and sea.”

The minister added that it’s hoped the website will “promote a much greater appreciation and awareness of our marine heritage and at the same time provide an essential tool to help the protection of this remarkable resource.”

#Archaeology - With yet another stormy weekend comes news that continued coastal erosion on the West Coast has exposed the remains of a shipwreck at Killary Harbour.

According to The Irish Times, the wreck on Tallaghbaun Strand is already known to locals though its origins are as yet unclear.

But archaeologist Michael Gibbons believes it could date from the late medieval period, as wrecks from the Spanish Armada have been identified in the region.

Gibbons has also been researching what appear to be the remains of a late Bronze Age or early Christian monastic site on Kid Island in Broadhaven Bay. The Irish Times has more on the story HERE.

#Shipwrecks - Two new shipwrecks have been discovered in Connemara in areas known to be used by smugglers in centuries past, as The Irish Times reports.

Currach fisherman John Bhaba Jeaic Ó Conghaíle found the skeletal remains of what's thought to be an 18th-century vessel at Cuan Chaisín in Ceantar na nOileáin.

Elsewhere, Fahy Bay resident Michael Barry located a second wreck, believed to date from the 19th century, near his home on the northwest Connemara coast – inshore from the Spanish Armada wreck Falco Blanco Mediano.

The area is known as the birthplace of sea captain George O'Malley, one of the most notorious smugglers of his day.

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.
