#HistoricBoats - A team of scientists aboard the Marine Institute's research vessel Celtic Voyager has revealed detailed images of World War I shipwrecks in the Irish Sea.

The team, led by Dr Ruth Plets of the School of Environmental Sciences at Ulster University, set out to capture the highest resolution acoustic data possible of WWI shipwrecks lost in the Irish Sea, using a new multi-beam system (EM2040) on board the RV Celtic Voyager to get the best data ever acquired over these wrecks.

"We were able to capture the most detailed images of the entirety of the wrecks ever," said Dr Plets. "Some of the wrecks, which are too deep to be dived on, have not been seen in 100 years. So this is the first time we can examine what has happened to them, during sinking and in the intervening 100 years, and try to predict their future preservation state."

Among the shipwrecks surveyed were the SS Chirripo, which sank in 1917 off Black Head in Co Antrim after she struck a mine; the SS Polwell, which was torpedoed in 1918 northeast of Lambay Island; and the RMS Leinster, which sank in 1918 after being torpedoed off Howth Head, killing over over 500 people - the single greatest loss of live in the Irish Sea.

Marine Institute chief executive Dr Peter Heffernan welcomed the achievements of the survey, supported by the competitive ship-time programme, saying: "The multidisciplinary team is making an important contribution to understanding and protecting our maritime heritage and to our ability to manage our marine resource wisely."

Explaining how the survey was carried out, Dr Plets added: "We moved away from traditional survey strategies by slowing the vessel right down to allow us to get many more data points over the wreck, with millions of sounding per wreck."

"The detail is amazing as we can see things such as handrails, masts, the hawse pipe – where the anchor was stored – and hatches. Some of the vessels have split into sections, and we can even see details of the internal structure. With the visibility conditions in the Irish Sea, no diver or underwater camera could ever get such a great overview of these wrecks."

As well as acoustic imaging, the team collected samples from around the wreck to see what its potential impact is on the seabed ecology. Sediment samples were also taken for chemical analysis to determine if these wrecks cause a concern for pollution.

The project is carried out to coincide with WWI centenary commemorations, noted Dr Plets. "We often forget the battles that were fought in our seas; more emphasis is put on the battles that went on in the trenches. However, at least 2,000 Irishmen lost their lives at sea, but unlike on land, there is no tangible monument or place to commemorate because of the location on the bottom of the sea.

"In the Republic of Ireland there is a blanket protection of all wrecks older than 100 years, so all these will become protected over the next few years. To manage and protect these sites for future generations, we need to know their current preservation state and understand the processes that are affecting the sites."

The next step for the team is to use the data collected to create 3D models which can be used for archaeological research, heritage management and dissemination of these otherwise inaccessible sites to the wider public.

"There is so much data, it will take us many months if not years, to work it all up," said Dr Plets. "Some of the wrecks are in a very dynamic environment and we are planning to survey these vessels again next year to see if there is a change, especially after the winter storms. That will give the heritage managers a better idea if any intervention measures need to be taken to protect them.

"These data could well signal a new era in the field of maritime archaeology. We hope it will inspire a new generation of marine scientists, archaeologists and historians to become involved. Above all, we want to make the general public, young and old, aware of the presence of such wrecks, often located only miles off their local beach."

The research survey was supported by the Marine Institute, through its Ship-Time Programme, funded under the Marine Research Sub-Programme by the Government.

The diverse team included maritime archaeologists Rory McNeary from the Northern Ireland Department of the Environment and Kieran Westley from the University of Southampton; geologists Rory Quinn and Ruth Plets, both Ulster University; biologists Annika Clements from Agri-Food and Biosciences Institute and Chris McGonigle from Ulster University; Ulster University marine science student Mekayla Dale; and hydrographer Fabio Sacchetti from the Marine Institute who works on Ireland's national seabed mapping programme INFOMAR, run jointly with the Geological Survey of Ireland.

The team blogged about the seven-day survey at Scientists@Sea.

#Shipwrecks - Mail Online is hosting some astounding photographs of wrecks lost off Malin Head during the World Wars as captured by amateur diving enthusiast Steve Jones.

The Welshman made his way around the final resting places of four military and supply vessels – HMS Audacious, SS Justicia, SS Empire Heritage and SS Laurentic – off the Donegal coast during a recent dive expedition.

The latter of these ships is believe to still hold £6 million (€7.6 million) in gold bars somewhere in or around its ghostly hull, though Jones and his team had no luck finding them.

They did however find the seaweed-blanketed remains of a number of Sherman tanks that were being transported by the SS Empire Hertiage.

The so-called 'lost ships of Malin Head' are just some of the numerous wreck sites off the North Coast that was a strategic route for the Allies during both wars and as such a prime target for torpedo and mine attacks.

#DIVING - The Sub-Aqua Club at NUI Galway and the Galway-Mayo Institute of Technology welcomes diving expert Edward Bourke to the NUI Galway campus on 18 October to give a talk on historical wreck diving in Ireland.

The talk will take a look at some of the exploits of wreck and salvage dives in Ireland over the years, exploring the nation of the Irish coast as a hotbed of pioneering subaquatic activity, driven mostly by the recovery of shipborne cannons - not only because of their expense, but also to prevent their falling into the hands of insurgents.

Bourke will give his talk at the Siobhán McKenna Theatre in the Arts Millennium Building at 7pm on Thursday 10 October. The evening will be of interest to local historians and divers alike. And as much of the activity was on the west coast, there is some local maritime interest, too.

Edward Bourke is a microbiologist, maritime historian and diver with Viking Sub Aqua in Dublin for 30 years and has dived in Australia, South Africa, Spain, Croatia, France and UK as well as Ireland. He has published three volumes on Shipwrecks of the Irish Coast, cataloguing some 6,000 wrecks in Irish waters, as well as a book of Irish shipwreck photos and a volume on the wreck of the Tayleur at Lambay Island. A scientist with Diageo, Bourke's most recent publication is a history of Guinness.

With the Lusitania expedition in the news, Saturday's Irish Times presents a guide to some of Ireland's most interesting diving sites for all levels of experience.
Though Ireland can boast an abundance of shipwreck sites, a number of them are off-limits to anyone but the hardiest expert explorers, while others require a licence from the Department of Hertiage.
But open dives are still plenty, such as the wreck of UC-42 off Roches Point in Cork, which happens to lie in a popular diving range, and the Empire Hertiage, which lies 30km off the coast of Malin Head and is regarded as one of Ireland's best wreck dives.
Among the licenced dives, the HMS Vanguard - which was tragically sunk 19km east of Bray by its sister ship Iron Duke in 1875 - is a top contender, with the summer months providing astounding visibility of the ships 9in guns.

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.
