Any ship coming into Dublin Port in today’s gales after crossing the Irish Sea will have felt mighty glad to get into the shelter of the port. But for P & O’s European Endeavour late this morning, there was the additional tricky matter of getting turned in the river without taking out the Poolbeg Y & BC marina, and then going astern into her berth in the Alexandra Basin writes W M Nixon.

Fortunately the renowned Dublin Port push-me-pull-you tug Shackleton (one of the pair with her sister-ship Beaufort) was on hand to show what she can do when a real heave in any direction is needed, and though it took time, the Endeavour was lined up and slid neatly into place.

Many Afloat.ie visitors will be familiar with the “Ballet of the Tugs” performed by Shackleton and Beaufort during the Dublin Riverfests. But as this morning’s task showed, while the tugs may well be game to perform as an all-singing all-dancing act, when there’s work to be done they’re more than able for it, as this sequence shows. The photos as usual fail to capture a sense of the real strength of the breeze – Dublin Airport was recording 40 knots with 50 knot gusts, and it got fresher after that, a real winter gale. But when summer comes, doubtless we’ll see the ballet again, and we sign off with a pic of that.

#INLAND WATERWAYS - Waterways Ireland has taken delivery of its third tug boat from Mooney Boats of Killybegs.

Designed by Marine Design International, the Inish Fendra is an 11.2-metre LOA steel-built tug which has been specifically tailored for operation on the Shannon-Erne waterway system.

Its design bears many similarities to the Inis Muillin, which was delivered by Mooney Boats in 2010.

According to Maritime Journal, the design process "involved significant input from the vessel operators and managers combined with the latest technology and ideas from the designers and builders to improve on efficiency" and safety.

A key feature of the Inish Fendra is its 3,500-litre ballast tank and pumping system, which is operated by the push of a button and can reduce the vessel's air draft by 0.2m.

As the Russian 'A' class Mir passed the LE Aoife off Dunmore East in mid-morning, the largest tall ship of the festival headed the start of the Parade of Sail, writes Jehan Ashmore.

Crowds left their cars in fields outside Dunmore East and descended into the harbour and surrounding headlands to witness the highlight of the four-day festival. Adding to the scene were the numerous leisure-craft, yachts and intrepid kayakers that gathered to greet the procession which took some two hours to pass the fishing harbour.

No sooner had the fully-rigged ship Mir had slipped beyond the anchored naval vessel that the gaff schooner Johanna Lucretia, under full sail came closer into view. She was closely followed by the Ocean Youth Trust Scotland's Bermudan cutter Alba Explorer.

Of all the 45 tallships participating the Columbian Navy's barque ARC Gloria presented the most colourful entrant. She proudly flew a large horizontal tricolor of yellow, blue and red representing the South American nation.

When it came to the turn of the Europa to pass the LE Aoife, the tug Bargarth gave a wonderful send-off with the traditional display of water jets shooting sky-high, nearly reaching the top of the three-masted barque.

Marking the tail-end of the parade was the Jubilee Sailing Trust's Lord Nelson, another barque that departed the estuary with the Hook Head Lighthouse forming a majestic backdrop.

At this stage several of the large tallships could be seen on the far horizon in preperation to the start of the first race leg of this years Tall Ships Races....next port of call Greenock!

Lord Mayor of Dublin and Admiral of Dublin Port, Gerry Breen, performed the 523 year-old "Casting of the Spear" ceremony in Dublin Bay on midsummer's day, writes Jehan Ashmore.

The 'casting' for yesterdays' re-enactment by the Lord Mayor took place onboard the Dublin port Company tug Shackleton.

From the deck of the Spanish built 50-tonne bollard pull tractor-tug, a spear was launched into the sky and fell deep into the cold water's of Dublin Bay. The ceremony once again marked the position of the city boundaries eastwards.

The medieval tradition of 'Casting of the Spear' dates back to 1488 when the then Lord Mayor, Thomas Mayler, set out on his horse to ride the city's boundaries.

According to historical records he rode out onto the strand as far as a man might ride and from there he cast a spear into the sea. At that time, casting the spear demonstrated the extent of the city boundaries eastwards.

The tradition marks one of many significant moments in Dublin Port's long history since its establishment as a trading post some 1,200 years ago.

The Irish flagged general cargo-ship Arklow Raider which went aground when departing Drogheda Port on Tuesday, remains stuck on a sandbank tonight, writes Jehan Ashmore.
In strong south-east gales the 90-metre vessel with a cargo of cement bound for Swansea, ran aground off the port's north breakwater. There were plans to tow the 2,999 gross tonnes vessel this morning but no large tugs were available to assist. It is expected that a tug will arrive at the scene tomorrow.
Meanwhile the crew of the Arklow Raider remain onboard the vessel which is in no danger. The dry-bulk cargo ship vessel is owned by Arklow Shipping Ltd and is one of nine 'R' class sisters built by the Dutch shipbuilders Barkmeijer Stroobos B.V.

The Drogheda Port Company's patrol launch, Boyne Protector has been monitoring the situation as the Arklow Raider lies close to the entrance of the Co. Louth port.

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.
