#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that umbilical installation and associated works between the Corrib Gas Field and the mainland and Broad Haven Bay in Co Mayo will commence tomorrow 8 May.

The area of activity stretches along the route of the existing Corrib pipeline, and will continue till the umbilical pull-in to Glengad and subsequent lay away of the umbilical next month, followed by further tie-in works in the Corrib field to be completed by mid-July, weather permitting.

A number of work and service vessels will be used throughout the offshore works period, with various tasks from installing the main umbilical to post-lay jetting.

In order to create a safe working environment for the near-shore diving activities and the umbilical pull-in, a Safety Zone around the bellmouth (250m radius) will be identified with red marker buoys spaced at 75m interval around the circumference of the zone.

All vessels in the vicinity are requested to keep clear of the works as these works progress along the pipeline route and to comply with requests from support vessels and safety boats.

Furthermore, all vessels are requested to monitor and comply with the Radio Navigational Warnings that will be broadcast for the duration of the works. All vessels involved in the operations will be listening on VHF Channel 16 throughout the project.

Full details of co-ordinates of the work area and the work vessels involved are included in Marine Notice No 20 of 2013, a PDF of which is available to read or download HERE.

#MarineNotice - Further to the recent notice of a 2D seismic survey in the Atlantic waters of the Irish continental shelf, Marine Notice No 14 of 2013 advises mariners of two full 3D seismic surveys in the Celtic Sea off the south coast.

CGG will be conducting the surveys on behalf of Fastnet Oil & Gas as part of its option on the Deep Kinsale Prospect, as previously reported on Afloat.ie.

The works are expected to commence in later this month and are expected to last around 50 days, subject to weather, beginning with the Deep Kinsale survey followed by the Mizen survey.

The seismic vessel SR/V Vantage (Call sign LMHY3) is scheduled to carry out the work. The vessel will be towing 10 cables, each 6km long with 100m separation for a total width of 900m, at a depth of seven metres. The vessel will also tow two source arrays, each made of three subarrays, each with a width of 16m and at a depth of six metres.

The seismic vessel will be accompanied by support vessel M/V Oms Resolution (Call sign HP5135) and chase vessel M/V Stormbas II (Call sign V4EM2).

In addition, as part of the Deep Kinsale survey, a second 3D seismic vessel M/V Artemis Angler (Call sign LAGU7) will assist in an undershoot of the Kinsale Alpha and Bravo platforms. The two 3D seismic vessels will sail in parallel at the same speed, one on each side of the platforms using streamers. The undershoot aspect of the acquisition is expected to last two to three days.

The seismic vessels will be restricted in their ability to manoeuvre whilst carrying out the surveys and all other vessels are requested to give these operations a wide berth. All project vessels will be listening on VHF Channel 16 throughout the project.

All vessels, particularly those engaged in fishing, are requested to give the SR/V Vantage, the M/V Artemis Angler and their towed equipment a wide berth and keep a sharp lookout in the relevant areas.

Full details of co-ordinates of the survey areas are included in Marine Notice No 14 of 2013, a PDF of which is available to read or download HERE.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport advises mariners that ENI Ireland BV is scheduled to conduct a 2D seismic survey in the Atlantic waters of the Irish Designated Continental Shelf.

The planned start of the survey is mid-April 2013 and, weather permitting, will continue until mid-October 2013.

The proposed survey consists of 18,000km of a full-fold 2D seismic survey in offshore waters beyond the 12-nautical-mile limit, and extends into international (high seas) waters.

The seismic acquisition will be carried out by the seismic vessel M/V BGP Explorer (Call sign HP4919), which will be accompanied at all times by guard vessel M/V Alk Explorer (Call sign HO2639). In addition, M/V De Vrouw Marie (Call sign HP9974) will act as a supply vessel for the re-supply of materials.

M/V BGP Explorer will tow a single solid 10km streamer. The vessel will travel at 4–5 knots and the streamer will be located approximately 10 metres below the surface. All vessels will be listening on VHF Channel 16 throughout the project.

The notice requests all vessels, particularly those engaged in fishing, to give the M/V BGP Explorer, the M/V Alk Explorer and the supply vessel a wide berth, and keep a sharp lookout in the relevant areas.

Details of co-ordinates for the seismic survey are included in Marine Notice No 13 of 2013, a PDF of which is available to read or download HERE.

Notice of this latest seismic survey comes after the news that the European Commission has sought an explanation from the Government over why it has not conducted environmental impact assessments for such operations in Irish waters, which are a designated whale and dolphin sanctuary.

Meanwhile, another recent Marine Notice advises passenger ship operators of the requirements for vessels engaged in the tendering of passengers between ship and shore.

Full details on the relevant provisions of the Merchant Shipping Acts are included in Marine Notice No 12 of 2013 available 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.
