The Department of Transport has been advised that geotechnical surveys will be undertaken in the Irish Sea off the Wicklow coast to provide site investigation information to facilitate the development of phase two of the Arklow Bank Wind Park project.

It’s anticipated that the survey works will commence by the end of June and be completed by the end of October 2023, subject to operational and weather constraints.

Surveys will be conducted by the jack-up barge OCM 80 Mariner (Callsign OCM 80) and MV Connector (Callsign OYOJ2). The survey activities will include approximately five boreholes and various seabed penetration tests, and the vessels will be operating on a 24-hour basis.

The OCM 80 Mariner is an 18m jack-up barge with a draught reported to be 1.2m and beam of 12m; the barge is positioned by a support tug. The MV Connector vessel is a 90m DP2 multipurpose vessel, with a current draught reported to be 7m and beam of 19m.

As these vessels will be restricted in their ability to manoeuvre when surveying, all other vessels are requested to leave a wide berth. Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

A fisheries liaison officer will be available to discuss operations in advance and throughout the duration of the survey campaign.

Coordinates and a map of the survey area as well as contact details can be found in Marine Notice No 37 of 2023, attached below.

A wind turbine off the coast of Co Wicklow is believed to have been struck by lightning amid an intense thunderstorm on Wednesday afternoon (19 October).

Smoke was spotted billowing from the 3.6MW turbine in the Arklow Bank Wind Park as the Status Orange weather event brought lightning and heavy spot flooding along the East Coast.

A statement from the Department of Transport as received by the Irish Mirror said: “There were no personnel in the vicinity of the turbine so no risk to life.

“The company are dealing with the incident and the Coast Guard have issued a Radio Navigation Warning to alert vessels in the area.”

A geophysical survey is set for the Irish Sea off the Wicklow coast to provide site investigation information to facilitate the development of the Arklow Bank Wind Park.

The survey work was anticipated to get under way by Wednesday 31 August and be completed by the end of October, weather permitting.

This survey campaign will be confined to the proposed Phase 2 of the Arklow Bank Wind Park, according to Marine Notice No 58 of 2022.

The Arklow Bank area is located around 3-7 nautical miles off the coast of Co Wicklow and consists of a north-south-trending sandbank around 12nm in length and sub-parallel to the coastline between Ardmore Point and Kilmichael Point.

Operations will be conducted by the Roman Rebel (callsign 2ICA5) and Lady Kathleen (callsign EIXT2).

As these survey vessels will be restricted in their ability to manoeuvre when surveying, due to the deployment of the towed survey equipment, all other vessels operating within their vicinity are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Work will be conducted on a 24-hour basis on the Roman Rebel with 12-hour operations on board the Lady Kathleen. Both vessels will display appropriate lights and signals.

Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

For contact details, plus coordinates and a map of the survey area, see the attached Marine Notice below.

A new planning regime will allow SSE Renewables to expand the second phase of its Arklow Bank Wind Park, as RTÉ News reports.

Under the new Maritime Area Planning Act, the company is seeking to boost its proposed expansion of the offshore wind farm project from a previously planned 520MW per year to 800WM.

SSE Renewables had previously developed its plans under the Foreshore Act but will now transfer to the new Marine Area Consents (MACs) scheme kick-started earlier this week by Minister for the Environment and Climate, Eamon Ryan.

The company’s Barry Kilcline said: “We expect to be able to invest around €2.5 billion in the revised project to deliver a new 800MW offshore wind farm by 2028 which will produce substantially greater power generation output at Arklow Bank than under our previous plans.”

A foreshore licence granted for expansion of an offshore wind farm near Arklow now faces a High Court challenge from an environmentalist and planning activist, as The Irish Times reports.

Peter Sweetman — whose previous objections include the proposals for a sea wall at US President Donald Trump’s Doonbeg golf resort — claims the purpose of the licence for site investigation works is to expand the current Arklow Bank Wind Park site from seven up to as many as 200 offshore wind turbines.

He also calls for ministerial decisions which resulted in the licence being granted to be quashed, arguing that they go against the EU Habitats Directive.

Metocean devices will be deployed in the Irish Sea off the Wicklow coast) in the coming days, weather permitting, to provide environmental data for the development of the Arklow Bank Wind Park.

Similar to last autumn’s deployment, four separate devices to monitor waves and currents will be deployed, which will include a seabed frame with the sensors mounted on it, an anchoring system, and a surface marker buoy.

The devices will be deployed using either the AMS Retriever (Callsign MEHI8) or Husky (Callsign 2EQI7), both versatile multi-purpose shallow draft tugs. The devices will remain in place for approximately six months, serviced on a three-monthly basis.

During deployment and recovery operations, the AMS vessel will be restricted in its ability to manoeuvre. The devices will be located using yellow special mark buoys which will have the relevant markers and ATON characters.

The location of the devices will be off the Wicklow coastline as detailed in Marine Notice No 31 of 2020, which is available to download below.

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.
