#MANX FERRY – The IOM Today reports that the Manx Government is drawing up plans to ensure that any wind-farms built within the waters off the island would not affect ferry routes.

Work on the Isle of Man Marine Plan is under way and the Department of Environment, Food and Agriculture's director of environment Martin Hall said it was important it was completed in a 'timely manner'.

One of the plan's objectives would be to identify current activities in Manx waters and safeguard their ongoing use. Mapping the location of navigation corridors, important natural areas and pipelines/cables will enable the island to identify potential wind farm sites that will not adversely affect current uses of the Manx marine environment, including ferry routes and fishing.

The comments come following criticism from the Isle of Man Steam Packet Company over Centrica's plans for a wind farm in the Irish Sea, outside Manx waters. The Steam Packet says that Centrica plans to develop in the path of two routes: Douglas-Liverpool and Douglas-Heysham, in spite of complaints from the ferry operator.

#POWER FROM THE SEA - A new marine research lab in Cork Harbour could help Ireland to be a global leader in renewable energy, the Irish Examiner reports.

The Beaufort Laboratory, being built on a three-acre site next to the National Maritime College of Ireland on Haulbowline Island, is set to be completed by 2016.

And scientists at the €14 million lab have told Minister for Energy Pat Rabbitte that it will be the largest marine renewable energy research facility in the world.

Expected to be a base for 135 researchers from University College Cork (UCC), the lab also hopes to attract the world's top researchers in marine energy to the area, with an aim to exploiting the potential for jobs in the fast-growing ocean energy sector.

The new lab forms part of the Irish Maritime and Energy Resource Cluster (IMERC) established to promote the country as a world-renowned research and development location, as previously reported on Afloat.ie.

#POWER FROM THE SEA - An Irish firm has landed a contract to provide a wave device for a new offshore energy test site in Cornwall, Siliconrepublic reports.

Ocean Energy, which is based in Cork, will deploy its first full-scale wave energy device at Wave Hub - described as an 'electrical socket' for testing wave power technology - off Hayle in north Cornwall by the end of the year.

The technology behind the buoy-type device, which will cost €9 million, has been developed over the past three years via a quarter-scale prototype in Galway Bay.

Using the principle of the oscillating water column, the device works by channeling water through a submerged chamber that forces air through a turbine above the surface.

The full-scale unit is expected to generate enough electricity to power as many as 1,200 homes.

#NAVAL SERVICE-The Naval Service are considering wind-power in an effort to reduce soaring fuel costs using "kite sails", reports the Examiner.

Commodore Mark Mellett confirmed the navy was collaborating with Irish Maritime and Energy Resource Cluster (IMERC), UCC, and CIT to develop "kite sails" which would be used to save fuel when a ship was carrying out surveillance.

"The kites would be used to reduce our energy bills, as we use 40% of the fuel allocated to the Defence Forces," said the commodore. "They could provide us with a speed of up to eight knots, which is as fast as a normal trawler."

The sails will have an added hi-tech edge (fitted with sensors to enhance the ships' radar capacity) which the service hopes to sell to other navies around the world. To read more about this story click HERE

#POWER FROM THE SEA - This morning the wind farm turbine installation vessel Sea Energy, departed Wicklow Bay having spent over a fortnight based in Wicklow Port, where her Danish crew celebrated Christmas Day, writes Jehan Ashmore.

The Esbjerg registered vessel operated by A2 Sea, arrived in the week before Christmas to work at Airtricity's Arklow Bank Wind Farm, but the nature of the work was based on internal operations only at the seven turbine facility, which each structure scaling to a height of over 70 metres / 240 feet.

Upon completion of her work, she returned to Wicklow where her crew spent the festive season in port with a Christmas tree complete with  lights! at the bow.

She remained in the harbour into the New Year and during the recent spate of heavy weather until finally departing yesterday on Little Christmas, where she overnighted in the bay.

With four towering supporting jack-up legs each 32 metres  high, this enables her to carry out offshore crane operations with greater control. In addition the vessel is raised completely above the water to gain elevation to assist mounting the pre-assembled wind-turbine components from her deck cargo.

She can work in waters of up to 24 metres and as she rests on the sea-bed this provides a more stable working platform.

Sea Energy presented a distinctive profile while in port as she 'sat' close to the Packet Quay, as her jack-up legs make mooring ropes redundant.

The quay is the main commercial quay and during this week she vacated the berth to allow regular caller Scot Isles (2001/2,595grt) which arrived with a cargo of sawn packaged timber products from Scandinavia. Owned by Scot Line, the vessel remained in the port for two days and then departed for Warrenpoint.

The Wicklow Port Company also specialise in dry-cargoes, lead, and scrap-metal as previously reported, to read more click HERE.

It is somewhat unusual for vessel movements in Wicklow to berth outside the harbour piers, as in the case with Sea Energy.

She shifted berths to the seaward side of the West Pier and again she sat with jack-legs lowered in water depths of six metres, leaving a clearance of around two metres below the keel.

Although Arklow is closer to the wind-farm than Wicklow, Sea Energy's 3,332 gross tonnes is too large to be accommodated as the port on the River Avoca has a has lower water depth.

#POWER FROM THE SEA - The Sustainable Energy Authority of Ireland (SEAI) is teaming with IBM in a new project to assess the noise levels of wave energy devices off the Irish coast.
The scheme will see an array of noise sensing equipment such as hydrophones deployed in Galway Bay to monitor the noise levels of wave energy conversion devices in real time, as well as map patterns of marine life in the area.
According to AOL Energy, noise pollution at sea is a chief concern, having a disturbing effect on fish migrations among other marine ecosystems.
The west of Ireland will prove an important case study in this regard, as it hosts one of the world's largest wave energy infrastructures.
"Underwater noise is a global environmental issue that has to be addressed if we are going to take advantage of the huge potential of ocean energy," said EU Commissioner for Research, Innovation and Science, Maire Geoghegan-Quinn.

One year countdown begins for Ireland's first electricity interconnector to Great Britain

The largest state energy infrastructure project, connecting the Irish electricity grid and Great Britain advanced significantly today as work began to lay cables under the sea bed of the Irish Sea. The €600m East West Interconnector project is being developed by EirGrid – the independent electricity transmission system operator in the Republic of Ireland.

The Interconnector is essential strategic economic infrastructure linking Ireland to the much larger energy markets of Britain and Europe.

It involves the laying of 180 kilometres of undersea and approximately 80 kilometres of underground cables to enable the flow of electricity in both directions between Ireland and Great Britain. This means that when Ireland needs extra electricity it can import it but crucially, it opens a new export market for Ireland's abundant renewable energy.

With most of the underground cables now laid, the cable-laying ship the Nostag 10 anchored itself at North Beach, Rush Co. Dublin to lay the marine cables of the €600 million project partly funded by the European Union. This unusual vessel, off the North Dublin coast, is already attracting curious onlookers.

Yesterday the ESRI issued a report which confirmed that the creation of a single EU-wide electricity market offers significant benefits for Ireland. The report, entitled the Internal EU Electricity Market: Implications for Ireland concluded that 'the single EU electricity market should result in lower electricity prices and increased competition as suppliers from Great Britain and beyond will be able to enter the Irish market. This should spur efficiency and increase consumer choice.'

As the cable laying got underway, Minister for Communications, Energy and Natural Resources, Pat Rabbitte TD was present to observe this key milestone for the project with just one year to completion when trading will commence on this interconnector.

Commenting on the project, Minister Rabbitte said, "The interconnector will improve security of supply, as well as increasing competition and assisting in achieving our ambitious renewable targets. I am delighted that EirGrid are on track to complete the project within budget and on time, by the end of next year.

"Witnessing the laying of the marine cable across the Irish Sea is symbolic of linking Ireland, a geographically isolated Island, to the single European energy market which will ultimately benefit all electricity consumers and generators."

As the Nostag 10 makes its way across the sea, the cable will be carefully lowered into the water and laid in a narrow trench which will be opened and closed by a remote controlled vehicle operating on the sea bed. The cable laying work is expected to take approximately eight months to complete.

Andrew Cooke, EirGrid's Director of Grid Development, said "This is a very exciting stage in the project and probably one of the most challenging. Before work started, EirGrid carried out a detailed marine survey to identify a route for the undersea cable that would have the least impact on marine life.

"With over 600 people currently working on the project, it is great to see the interconnector cable finally beginning to be laid at sea. Europe's electricity future will be reliant on interconnector projects of this nature and currently EirGrid is investigating the feasibility of further interconnection to Europe."

The Interconnector is scheduled to be operational in late 2012 and will be capable of carrying power to supply the equivalent of 300,000 homes.

New Scientist has highlighted some of the latest technologies being developed to harness power from the sea.
Companies such as Pelamis Wave Power and Aquamarine Power are already testing prototypes of their so-called wave energy 'harvesters' - enormous machines that can capture the massive potential energy stored within ocean waves.
Pelamis' huge P2 is filled with state-of-the-art computers that allow programmers to control and update its operations on the fly, quickly taking advantage of changes in sea conditions to maximise energy production and increase efficiency.
The proof is in the pudding, as P2 can produce 750 kilowatts of power - twice as much as earlier prototypes.
Aquamarine's Oyster 800, meanwhile, can generate an incredible 800 kilowatts by way of a giant hinged flap that juts out of the water. Each passing wave closes the flap shut like a clamshell, with the resultant hydraulic pressure driving an onshore turbine.
"If you can get that sort of level of performance improvement then the economics suddenly start to look a lot more favourable," says The Carbon Trust's Stephen Wyatt.

Belfast Harbour could potentially become one of the leading energy renewable hubs in the UK, when DONG Energy, a leading Danish energy firm, signed a letter of intent yesterday for an agreement to progress on a number of offshore wind farm projects in the Irish Sea.

In addition as part of the project, Belfast Harbour are to invest £40m in the development of a new 450-m long quay. The facility will be adjoined by a 50-acre logistics space on the southern shoreline of the port's docklands estate on Belfast Lough. The construction phase will create 150 jobs and up to 300 full time positions when the facility is completed, where the wind turbines and their foundations will be pre-assembled.

At that stage the large wind farm components will then be loaded onto specialist wind farm installation /construction vessels as depicted on the image by clicking here and to read further information on the overall project.

Attending the announcement which was held in Belfast Harbour Office, were representatives from the Northern Ireland Executive, Peter Gedbjerg, Vice President and UK Country Manager of DONG Energy, and Len O'Hagan, Chairman of Belfast Harbour. The energy hub scheme represents one of the harbour's largest ever capital investment projects.

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.
