It’s been confirmed that two of three logboats spotted by drone in the River Boyne in recent weeks are new discoveries, and could date from medieval times.

As previously reported on Afloat.ie, citizen archaeologist Anthony Murphy captured the first of his unique aerial images while searching for a dolphin that’s been delighting Drogheda’s denizens.

Over subsequent days he spotted the outlines of two more logboats in close proximity, though he presumed they were among a number of such vessels already known to the National Monuments Service (NMS).

But as RTÉ News reports, the NMS has now confirmed that the first and third boats spotted by Murphy are indeed new discoveries — and could date from the Norman fortification of Drogheda.

A citizen archaeologist may have spotted the remains of two previously unknown medieval logboats in the River Boyne.

Last week, The Irish Times reported on Anthony Murphy’s drone footage of a rectangular object in the riverbed captured on Monday 26 April, while he was observing for the dolphin recently spotted in the river near Drogheda.

The National Monuments Service (NMS) suggests this may be a vessel first discovered last year and which could be as much as 1,600 years old.

Subsequently, Murphy reported a second sighting on Wednesday 28 April, at a location some 200 metres from the previous find.

“It appears to be upside down, is very flat-bottomed and is larger than the first one,” he wrote on Twitter.

Further aerial investigations over the weekend revealed what appears to be a third logboat some 400 metres downstream of the first, west of the Bridge of Peace.

Murphy details the find on his blog Mythical Ireland, where he estimates this third vessel to be around 15ft in length.

However, he harbours no illusions that his “discoveries” have never been spotted previously.

“I’m assuming this is one of these ‘few’ logboats which NMS says it is aware of in the River Boyne at Drogheda,” he says. “However, the drone photography of same brings a new perspective on these ancient artifacts.”

As for why these remnants of Ireland’s ancient history are becoming easier to find now, Murphy believes it’s a combination of “exceptionally low” spring neap tides due to lack of rainfall, and clearer water due to reduced pollution in the river.

The Irish Independent covers the excitement among the denizens of Drogheda after a dolphin swimming up the River Boyne paid an unexpected visit to the town.

Reports of a dog in the water yesterday morning (Thursday 22 April) turned out to be wide of the mark when Boyne Fishermen Rescue and Recovery encountered the “medium-sized dolphin” in the River Boyne at the Upper Mell slipway, just east of the town centre and some 7km from the open sea.

The Irish Whale and Dolphin Group says the marine wildlife is likely to be a bottlenose and called for the public to contact it with any images or reports of further sighings.

While there is no immediate cause for concern, dolphins are saltwater animals and can develop serious kidney and skin problems with prolonged exposure to freshwater environments.

Independent.ie reports that a man has died in an incident while fishing on the River Boyne near Townley Hall, outside Drogheda yesterday afternoon, Saturday 27 June.

It’s understood that a man in his 30s was taken from the river two hours after he was reported in difficulty and later pronounced dead in what is being regarded as “a tragic accident”.

Drogheda Coast Guard had a prehistoric mystery on their hands earlier this week with what the station is calling “probably the most unusual tasking we ever had or ever will have”.

The coastguard team were tasked on Tuesday (26 February) after an emergency call reporting ‘dinosaur bones’ in the River Boyne close to Drogheda town centre.

And indeed when they arrived the volunteers discovered what appeared to be the skeletal remains of a Tyrannosaurus rex half-submerged in the mud.

But on closer inspection, the bones were revealed to be “a very impressive imitation”.

Drogheda Coast Guard officer in charge Dermot McConnoran told TheJournal.ie that the plaster-cast bones were covered in silt suggesting they’d been in the river for some time.

Further research has turned up images of the same skeleton “in a less river-worn state” from a little over a year ago. It’s not yet known who is responsible for its creation.

#Rescue - The Irish Independent reports that a 13-year-old boy has been rescued after falling into the River Boyne in Drogheda last night (28 December).

It's believed the boy had been playing close to the edge of the river opposite the Louth town's Garda station when he slipped into the water.

The casualty was kept afloat by a life ring thrown by a passer-by till he was rescued by the Irish Coast Guard.

#Coastguard - The Howth unit of the the Irish Coast Guard responded this weekend to a vessel that lost power at the mouth of the River Boyne.

Howth's coastguard crew were undertaking helm training with a passage to the Drogheda unit to support the Drogheda Marina launch when they were notified that a ski-boat planning to join the flotilla had lost power on the Drogheda Bar.

The vessel, with four people aboard, was taken under tow - while a mother and child on a second vessel suffering from serious sea-sickness were also transferred to the coastguard boat.

As previously reported on Afloat.ie, the Drogheda Port Company undertook dredging works in January this year on the entrance to the port on the River Boyle, following earlier works in 2010 to remove sand accumulating at Drogheda Bar.

#PORTS & SHIPPING – Drogheda Port set a record tonnage cargo with the arrival of Arklow Bridge (2011/4,723grt) last week. The vessel operated by Arklow Shipping N.V. as previously reported on Afloat.ie had carried 7,125 tonnes of maize, the largest ever single cargo handled in the Co. Louth port, writes Jehan Ashmore.

Arklow Bridge is the  second 'B' class vessel that was built last year and the Dutch-flagged vessel loaded the cargo of  maize in the Polish city of Gdynia for Comex McKinnon. The company is a leading player in the importation and trading of feedstuffs for the animal feed sector in Ireland.

Stevedoring services were handled by Fast Terminals, a new company which is a joint venture between Drogheda Port Company and Fast Shipping of Antwerp. The company became operational last Septemberand increases the number of stevedoring operations in the port to four.

Drogheda Port is developing its agri-sector business so to transport feedstuffs for the animal feed sector in Ireland. The agri-food sector is worth €7.8bn and is proving resilient, despite the downturn and growth from this indigenous sector will be vital to the country's overall economic recovery.

According to Drogheda Port Company, planning permission was recently received for the development of a 5,400sq m bulk storage facility at the Tom Roes Point Terminal. The downriver facility is situated closer to the open sea compared to the  towns quays on the banks of the Boyne.

Mr Paul Fleming, Drogheda Port Chief Executive said "Drogheda Port continues to provide a strategic import and export location for our customers with a service which is more flexible and cost competitive than other larger ports".

He added: "This is helping us to win new contracts and grow our business in addition to providing a platform to Ireland's importers and exporters to reach their markets more cost competitively."

Mr Simon Mulvany, Director of Fast Terminals said "Fast Terminals has identified the competitive opportunities that Drogheda Port can offer our company. Despite the current economic downturn we intend to invest in the port and develop our facilities to cater for further growth in the future."

#PORTS & SHIPPING- Berthed at the Steam Packet Quay, Drogheda is the suction-trailer dredger Lough Foyle (1979/868grt) which is on contract work with the Drogheda Port Company, writes Jehan Ashmore.

Following the sale last month of Hebble Sand, as previously reported on Afloat.ie (clcik HERE), the Lough Foyle (PHOTO) is now the only port-owned dredger on the island of Ireland. The Londonderry Port & Harbour Commissioners (LPHC) purchased the vessel from Dutch interests in 2009. She was originally the Saeftinge, built in 1979 at the Van Goor Scheepswerf in Monnickendam.

Since her introduction she has performed previous dredging operations to include the Drogheda Bar leading into the Co. Louth port. Her most recent contract was in Waterford Estuary, from where she arrived from on Tuesday after an overnight voyage.

In addition she has worked at the new Stena Line ferryport terminal at Loch Ryan, Cairnryan, to see related report click HERE. The Scottish ferryport is due to be officially opened tomorrow, to read more including the newly introduced 'Superfast' sisters click 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.
