The Department of Transport has been notified by JD-Contractor that they will be performing out-of-service cutting and route clearance works on behalf of Nexans for CIDAC as part of the Celtic Interconnector Project.

The works will be located at various points along the planned subsea electricity cable route between the southeast coast of Ireland and the northern coast of France.

Works will begin on Wednesday 24 April and will continue for approximately 10 days, subject to weather and operational constraints.

The out-of-service (OOS) cable-cutting operations will be conducted within the cable corridor extending plus or minus 50 metres each side of planned cable centreline. The relevant waypoints can be found in Marine Notice No 20 of 2024, attached below.

The works will be conducted by the vessel MV Detector (callsign OUIV2) which will display the relevant lights and shapes during periods of restricted manoeuvrability and adhere to the International Regulations for the Prevention of Collisions at Sea (COLREGS) and all licensing requirements.

During OOS cutting operations, the vessel will keep a listening watch on VHF Channel 16 and will actively transmit an AIS signal. A listening watch will also be maintained on VTS VHF channels as appropriate. The vessel will broadcast daily, and at shorter intervals as may be required by passing traffic, the vessel position, operational information and planned operations for the next 24 hours.

Maps and coordinates as well as contact details are included in the Marine Notice below.

Planning permission has been granted for the East Cork landfall segment of the €1bn Celtic Interconnector power link between Ireland and France, according to RTÉ News.

The 500km subsea cable, a joint project of EirGrid and France’s Réseau de Transport d’Electricité, will be the first direct energy link between the two countries, as previously reported on Afloat.ie.

Following a public consultation three years ago, a site at Youghal was chosen for the landfall section at the Irish end.

Approval by An Bord Pleanála covers the cable plus associated infrastructure such as that for power conversion and connection to the national grid.

Pending the granting of a foreshore licence for offshore developments, as well as a marine licence from UK authorities for the cable route, it’s expected the Celtic Interconnector could be activated by 2026.

The State’s electricity transmission grid operator EirGrid has opened a two-month consultation on proposed south coast landfall and converter station locations for its electricity link between France and Ireland writes Lorna Siggins.

The Celtic Interconnector will be the first direct energy link between Ireland and France, running some 500 km under the sea from east Cork to the French north-west coast. A further 40 km of underground cable will be laid on land.

The project is being jointly developed by EirGrid and Réseau de Transport d'Électricité, the French electricity transmission system operator, with a target completion date of 2026.

Eirgrid is seeking the public’s reaction to a shortlist of three proposed landfall locations, and a shortlist of six proposed location zones for a converter station in east Cork.

The convertor station converts direct current electricity to alternating current and vice versa.

It has scheduled a series of public information days in east Cork between April 23rd and May 3rd (see list below).

The state-owned company says that the link will “put downward pressure” on the cost of electricity, while improving security of supply, providing a direct fibre optic telecommunications link, and facilitating further development of renewable sources.

A previous consultation round had confirmed east Cork as the most suitable location in Ireland for the project, which will have a capacity of 700 megawatts (MW).

Eirgrid says this capacity is enough to power 450,000 households, and the cable will allow both the import and export of electricity.

Eirgrid says that the proposed shortlisted landfall locations - Ballinwilling strand, Redbarn beach, and Claycastle beach – between Ballycotton and Youghal in east Cork were selected from a list of five.

The proposed shortlisted sites for the converter station are in Ballyadam, Leamlara, Knockraha, Pigeon Hill, Kilquane and Ballyvatta - all inland and north of Cobh - and these locations were selected from a list of 14 options, it says.

Eirgrid says that each location was assessed against five criteria; economic, technical, environmental, socioeconomic and deliverability.

EirGrid is encouraging communities and stakeholders to “share their feedback” on the proposed shortlists.

“The shortlists are provisional. Feedback from communities, local representatives, and other stakeholders will be critical to ensuring that we can assess each option fully and make informed decisions when confirming the shortlists,” Eirgrid spokeswoman Louise Glennon states.

Stakeholders, communities and members of the public are invited to respond by Monday, June 10th, by online, by email, by phone, in writing or by attending one of a number of information days in east Cork, as below:

Lisgoold Community Centre - Tuesday 23 April - 2pm – 8pm

Knockraha Community Centre - Wednesday 24 April - 2pm – 8 pm

Carrigtwohill Community Centre - Tuesday 30 April - 6pm – 9pm

Midleton Park Hotel - Wednesday 1 May - 2pm – 8pm

Cloyne Parochial Hall - Thursday 2 May - 6pm – 9pm

Walter Raleigh Hotel, Youghal - Friday 3 May - 2pm – 8pm

#MarineNotice - The survey vessel VOS Sweet (Callsign PCPE) is currently conducting offshore geotechnical and environmental survey operations associated with the proposed Celtic Interconnector on behalf of EirGrid.

The VOS Sweet was set to commence operations yesterday, Monday 18 June, and will operate on a 24-hour daily basis for approximately two weeks in two main corridors off East Cork to three landfall points: Ballinwilling Strand (Ballycotton Bay); Redbarn Beach and Claycastle Beach (Youghal Bay).

The survey is to collect geotechnical data utilising a Vibrocorer (VC) and Cone Penetration Test (CPT) spread and environmental (benthic) data utilising Grab Sampler spread. The survey will be conducted under Foreshore Licence FS006811. Common frequency VHF Channel 16 shall be used throughout the project.

Details of the route centreline co-ordinates as well as intended locations for the VC, CPT and benthic sampling are included in Marine Notice No 26 of 2018, a PDF of which is available to read or download HERE.

Meanwhile, Providence Resources is carrying out a site survey on its FEL 6/14 licence, called Newgrange, situated between the Southern Porcupine and Goban Spur Basins some 260km off the South West Coast.

The eight-day geophysical survey by the MV Kommandor (Callsign MCJO2), was scheduled to commence on Monday, is using dual-frequency side scan sonar, single-beam and multi‐beam echosounders, side scan sonar, sub‐bottom profilers and magnetometer.

Seabed (benthic) samples will also be taken using a box corer or grab as appropriate, and geotechnical sampling will be undertaken with a piston corer to a minimum target depth of 6m below the seabed.

In addition to the above, and to accurately determine potential future drilling hazards over the Newgrange location, the proposed survey will also include a high resolution 2D seismic which is not expected to exceed two days.

Survey operations will be conducted on a 24-hour basis. The MV Kommandor will be displaying shapes and lights prescribed in the International Rules for the Prevention of Collisions at Sea (COLREGS) Rule 27, to indicate that the survey vessel is restricted in its ability to manoeuvre. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.

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.
