The Anglia Seaways became the last vessel of the DFDS Seaways fleet to depart Dublin yesterday, following the official closure of the operator's Irish Sea services at the weekend, writes Jehan Ashmore.
In January DFDS announced the closure of the Dublin-Liverpool (Birkenhead Twelve Quays Terminal) and the freight-only Dublin-Heysham routes with the loss of 200 jobs to include 50 shore-staff based at the Irish terminal.

The ro-pax Dublin Seaways made a last crossing with a Saturday morning arrival at Birkenhead. After disembarking passengers, vehicles and freight traffic, the 21,856grt vessel immediately departed the Mersey for a short-term deployment on the company's North Sea Rosyth-Zeebrugge service.

Sistership, Liverpool Seaways also completed her last crossing to Birkenhead with an overnight Saturday sailing. This was the final scheduled sailing under DFDS Seaways ownership and marked the last foot-passenger crossing on the Liverpool route as rival operators P&O (Irish Sea) and Seatruck Ferries do not cater for this market.

The vessel returned to Dublin yesterday from Birkenhead; this was to facilitate the loading of drop-trailers and terminal based tugmasters (engine-driven truck/cabs) that tow unaccompanied trailers on the roll-on roll-off vessels. After a short turn around at the terminal, Liverpool Seaways departed Dublin, bound for Immingham. The UK east coast port is where DFDS operate an extensive freight route network across the North Sea.

In addition the 13,704grt Anglia Seaways also docked in Dublin yesterday from Heysham to perform similar duties like the Liverpool Seaways. Several hours later, the 114-trailer capacity vessel set a southbound course past The Muglins, bound for Avonmouth.

DFDS cited its decision to exit entirely from Irish Sea sector due to the sharp decline in the Irish and UK economies in 2008 and 2009. The company suffered continuous losses on its remaining routes and the issue of over-capacity, particularly on the north Irish Sea.

Only last December, the Danish owned shipping operator sold its other two Irish Sea routes to Stena Line in a £40m acquisition deal. This is all the more remarkable considering DFDS Seaways purchased the previous route operator, Norfolkline's Irish Sea division of their four routes and seven vessels, in July 2010.

The sale to Stena covered the three terminals used on the Belfast routes to Birkenhead and Heysham, which is another freight-only service. In addition the acquisition involved the sale of the South Korean built freight-ferries Hibernia Seaways and Scotia Seaways; like the Anglia Seaways they were all former Norfolkline / Maersk Line vessels.

Interestingly the acquisition is to include the purchase of the chartered 27,510grt ro-pax sisters Lagan Seaways and Mersey Seaways. When the Visentini built sisters were completed at the Italian shipyard, they were placed on the Belfast-Birkenhead route in 2005.

On 1 December Stena Line UK Ltd acquired DFDS Seaways Irish Sea Ferries Ltd (since renamed Stena Line Irish Ferries Ltd). Although the acquisition of SL ISF by Stena Line has been completed and DFDS no longer owns SL ISF, Stena Line await formal approval from the Irish competition authority and the UK's Office of Fair Trading (OFT) to integrate SL ISF into the wider Stena Line business.

In the meantime during this transitional period, it is business as usual for customers using the Belfast-Birkenhead and Belfast-Heysham routes. Online bookings continue to be accepted on www.dfdsseaways.com or tel: (01) 819 2999 and in the UK tel: 0871 230 033

Three large vessels from one company arrived into Dublin Port on Sunday, to include an inaugural call of the 49,166 tonnes M.V. Pauline from Zeebrugge, writes Jehan Ashmore.
At 203-metres the Pauline built in 2006, made a special once-off sailing to the capital to cope with the demand in January car-sales imports. Nearly 1,000 vehicles were carried between the Pauline and the 195-metre Opaline which arrived later on the day from Rotterdam.

Normally the Pauline operates on other routes. She along with her sister Yasmine are the largest vessels in the Compagnie Luxemburgeoise de navigation SA (CLnd) / Cobelfret fleet. The vessels are of the Con-Ro design, also known as the 'HumberMax' vessels which have 5,632 lane metres capable of carrying 258 container trailers and 656 cars.

Apart from the Dublin debut of the Pauline which docked at Ocean Pier, the final vessel of the trio, Celestine (1996 / 23,986grt) was the first to arrive from Zeebrugge, docking at the ferryport berth 51A (also used daily by Stena Line vessels). Like the Pauline, the Opaline (2009 / 25,235grt) docked at Ocean Pier and is the newest and last of six newbuilds built from German yard of FGS Flensburg.

CLnD won the Short-Sea Shipping Company Award in 2010 at the Irish Exporter Awards in November and hosted by the Irish Exporter Association (IEA). The award was sponsored by the Irish Maritime Development Office (IMDO) which recognises the strategically important role of short sea shipping to our island economy.

There are four sailings operated by CLnD between Dublin Port and Rotterdam / Zeebrugge. From the Dutch port there are onward sailings linking Göteborg and Esbjerg while the Belgian route connects the UK ports of Killingholme, Purfleet and Ipswich.

The development of the Irish routes are part of the "Motorways of the Sea", an EU-wide programme to promote a modal shift of goods from congested roads to alternative sea transportation. In addition to the concept is the international trend in the use of larger and more efficient vessels.

In October 2009 CLnD /Cobelfret switched their Irish operations from Rosslare to Dublin Port. The transfer to Dublin allowed CLnD to introduce larger tonnage at the then newly upggraded No. 2 ro-ro linkspan at Ocean Pier, Alexandra Basin East.

CLdN ro-ro SA and CLdN ro-ro UK offer ro-ro connections from Belgium and the Netherlands to the UK, Ireland, Sweden and Denmark. Both divisions share a combined core fleet of 20 vessels. Some ships including the Pauline are registered and flagged from land-locked Luxembourg. The fleet operate on short sea ro-ro trade routes, occasionally supplemented by time chartered tonnage, which accommodate trailers, containers, vehicles and other rolling equipment.

DFDS Seaways recent announcement to close its operations on the Irish Sea this month is a major blow considering the Danish company entered the Irish-UK ferry market only six-months ago, writes Jehan Ashmore.
The Dublin-Birkenhead (Liverpool) and freight-only Dublin-Heysham service is to close at the end of this month. Up to 200 staff are to lose their jobs of which 48 are shore-based positions in Dublin Port. DFDS cite its decision to exit entirely from Irish Sea operations due to the sharp decline in the economies of both countries in 2008 and 2009 and the issue of over-capacity.

The routes represented a fifth of the freight market and will result in the withdrawal of the twin 21,856grt passenger ferry (ro-pax) sisters, Dublin Viking and Liverpool Viking on the 7-hour Mersey route and the 13,000grt freighter Anglia Seaways on the route to Lancashire.

In recent years, new tonnage notably in the form of four freight-only newbuilds commissioned for Seatruck Ferries on their Warrenpoint-Heysham and Dublin-Liverpool routes has added to intense competition in a crowded north Irish Sea ferry-freight sector.

The process to purchase Norfolkline's Irish Sea operations by DFDS Seaways was finally completed in mid-summer of last year. The acquisition saw the Scandinavian newcomer take control of four routes between Birkenhead-Belfast / Dublin and the freight-only Heysham-Belfast / Dublin services and a fleet of seven vessels, four (ro-pax) ferries and three freight-only vessels.

DFDS Seaways latest decision is all the more dramatic as the company in early December then sold both Belfast routes to Birkenhead and Heysham to Stena Line. In addition the £40m acquisition included the sale of the chartered 27,510 ro-pax sisters Lagan Seaways and Mersey Seaways and the 13,000grt freighter half-sisters, Scotia Seaways and Hibernia Seaways. The deal is significant in that Stena will make an inaugural foothold on the Merseyside market.

With the sea-changes swirling in the Irish Sea market, the dominant player is with out doubt Stena Line. The ferry operator closed late last year the Larne-Fleetwood route and three vessels (for more information about those vessels click here) yet the inclusion of the former DFDS Belfast-Heysham route is closely similar with neighbouring ports and newer larger vessels.

The acquisition by Stena of the loss making routes from DFDS last month also coincided with a review to be conducted by the Danish companies remaining Dublin routes to Birkenhead and Heysham. The findings of that review were concluded with this months' decision by DFDS to close down the routes, marking the Scandinavians operators brief foray on the Irish Sea ferry scene.

A second drill-rig platform, the Pauline was positioned in Dublin Bay on Friday, to investigate suitable conditions for an outfall discharge pipe from the Ringsend wastewater treatment plant, writes Jehan Ashmore.

The work is part of a Dublin City Council project to evaluate an extension at the Ringsend plant where treated water will be released into the bay. The council are conducting detailed feasibility studies which will be examined for an Environmental Impact Assessment.

To date the project has involved two other rigs, the Aran 250 and the larger Excalibur which remains in the bay. The barges will be towed to 20 pre-determined bore-hole locations in the bay where the jack-up rig barges operate 'legs' to sit on the seabed which enables a steady working platform. The rigs are operating on a continuous basis in an area covering most of Dublin Bay and close to the Burford Bank on the eastern fringes.

In addition a buoy will be positioned 300-metres of the barge during drill operations, which is expected to take approximately one week for each drill. For information on the location of the bore-holes, they can viewed from the Dublin Port website by clicking HERE The project is expected to be completed in late Spring.

Several support craft are engaged in the project that recently included the Seabed Worker, a 3,923 gross tonnes Norwegian anchor-handling tug supply vessel (AHTS) the tugs Multratug 7, MTS Valiant and Trojan and the RIB-craft sisters, Brian Boru and James Joyce which are on standby duties. Like the Trojan, the 12-seater RIBS are based at the Poolbeg Yacht Club Marina where in the tourist season the craft provide excursions in Dublin Bay for Sea Safari Tours. In October the project also required the services of the yellow-hulled catamaran, Xplorer to carry out a bathymetric survey of Dublin Bay. The larger tugs and rigs are based opposite in Alexandra Basin / Ocean Pier.

The largest drill-rig working to date on the project, the Excalibur arrived under the tow of the Multratug 7 on a misty morning on Christmas Day. Due to the weather conditions the red-hulled craft slipped quietly into the port. Several days later the imposing looking craft re-emerged with its six-towering jack-up 'sea-legs' that jutted skywards into an otherwise horizontal expanse of Dublin Bay.

The sight of the rig has presented many onlookers to mistakenly believe the drilling was for oil!...Not so but the assumption is not surprising given the reports last year of an oil-field discovery named the Dalkey Island Prospect. The name for the oil-field was referred to Dalkey, as the coastal suburb on the southern shores is the nearest landfall to the exploratory well sites at the Kish Bank Basin.

In fact this kind of exploratory activity was again to confuse residents throughout the bay when the drill-ship, Fugro Synergy was offshore at the Kish Bank between December 2009 and early Spring of 2010. Though on this occasion the search was not for oil but coal!

During this period the 5,200 tonnes vessel equipped with a drill-tower, seemed to be a near permanent feature on the horizon. A series of drill-wells up to 3,500-metres were conducted when the 2009 built ship was contracted to Irish based VP Power Ltd, to determine the commercial viability of extracting coal from the sea for generating electricity. The Underground Coal Gasification (UCG) project is a process where coal is heated in underwater rock reservoirs to extract gas, essentially converting gas-from-coal energy. Otherwise this method is commonly referred to as a 'clean' technology.

In addition to last year's search for deposits of large coal seams under the seabed, there was reports of a significant natural resource in the form of oil!... when several exploratory blocks again in the Kish Bank Basin were surveyed. The company behind this venture, Provident Resources, another Irish based exploration company, conducted initial oil surveys using air-born craft and as such no actual drill-based ships or rigs were used. Though should any oil flow, such an operation would be required.

Incidentally the Excalibur is designed also to perform offshore wind turbine installation work and is equipped with a 250-ton crane to hoist the wind-farm components. The vessel is operated by Fugro Seacore, a subsidiary of the Dutch parent company, Fugro, which also managed the drill-ship Fugro Synergy.

At this quiet time of the year, vessels from Irish Sea ferry operators are taken off routes to undergo annual dry-docking, writes Jehan Ashmore.

In the case of Irish Ferries, their Rosslare-Pembroke Dock route vessel, Isle of Inishmore arrived on the Mersey yesterday at the Cammell Laird dry-dock facility in Birkenhead.

The 1997 Dutch-built Isle of Inishmore had relieved the 50,938 tonnes 'flagship' Ulysses from the Dublin-Holyhead route which too had gone to Birkenhead for maintenance since January 4th.

The Ulysses is now back on service and the company's French routes cruiseferry, Oscar Wilde is covering the Isle of Inishmore's absence from Rosslare-Pembroke Dock sailings.

Continental services to France on the Rosslare-Cherbourg route will resume on February 16th when the Oscar Wilde returns from her overall. The Bahamas flagged vessel will re-open seasonal Rosslare-Roscoff sailings starting on May 13th.

In addition to conventional tonnage Irish Ferries also operate the fast-craft catamaran Jonathan Swift in tandem with Ulysses on the Dublin-Holyhead route. The Ulysses takes 3 hours 25 minutes while the 39-knot catamaran craft marketed as the Dublin 'Swift' is advertised with a scheduled passage time of 1 hour and 49 minutes.

The Australian-built catamaran was taken off the central corridor route yesterday to be drydocked also in Birkenhead until January 18th. Dublin Swift sailings return to the Dublin-Holyhead route on February 19th with the first crossing to depart at 14.30 hours from the capital port.

Vacancy at Seatruck Ferries

Seatruck Ferries, the only Irish Sea ferry company, dedicated solely to the carriage of freight, are looking to appoint a Group Operations Manager. The position is based in their Heysham office in Cumbria. In addition the appointment would require regular travel to Seatruck's other terminals on both sides of the north Irish Sea.

The company operates the Dublin-Liverpool, Warrenpoint-Heysham and Heysham-Larne routes which are served by an eight-strong fleet. In recent years four Spanish built newbuilds were commissioned into service on the Dublin-Liverpool and Warrenpoint-Heysham routes. Each newbuild has a 120 freight unit capacity.The remaining four vessels where built in 1998 and they can each handle 65 freight units.

Seatruck's Dublin Port operations is located at the Alexandra Basin terminal close to the East-Link Toll-Lift Bridge and the Point Village.

Salt Shipments Bound for Cork

As artic conditions persist throughout the country, another shipment of rock-salt is due to arrive at the port of Cork tonight, writes Jehan Ashmore.
The cargo-ship, CFL Prospect with 6,300 tonnes of salt onboard, set sail from the Mediterranean over a week ago and is expected to dock at Cork city-centre around midnight. The vessel's cargo will be unloaded tomorrow morning at the South Quays where over 100 trucks will distribute the salt to authorities around the country. Further shipments totalling 15,000 tonnes are due to be handled by the port over the festive period.

In total the National Roads Authority (NRA) will have 25,000 tonnes of salt available during the Christmas week, with 3,000 tonnes distributed to authorities on a daily basis. As a priority the salt will be used to grit the national primary network.  

The second bout of artic conditions that has gripped the country with temperatures plummeting to -17 degrees in the west and -15 degrees is forecast tonight in the north-west. Further snowfalls are also due in various regions tonight and with sub-zero temperatures expected to last up to St. Stephens Day. As such the demand for salt supplies has soared resulting in shipments sourced from overseas countries to include Turkey and Egypt.

CFL Prospect (see video-clip here) is owned by the Dutch shipping company, Kees Koolhof which since 2006 has built up a fleet of modern vessels to trade in the short-sea sector. The 2007 built vessel is one of nine Jumbo 6500s from a series completed by the Peters Shipyard at Krampen.

Two Dutch naval frigates, HNLMS Tromp and HNLMS Van Amstel are due to arrive into Dublin Port tomorrow for a courtesy visit over the weekend, writes Jehan Ashmore.

The Royal Netherlands Navy HNLMS Van Tromp is a De Zeven Provinciën-class air-defence and command frigate (LCF). The class has a striking streamlined visual appearance, through the use of stealth design technology. The stealth design is to minimise the vessels signature as much as possible from the detection of enemy vessels using radar.

At 6,050 tonnes, the stealth frigate is one of five built by the Royal Schelde Group, of Flushing, Netherlands. Spain and Germany also participated during the design stage of the 144-metre class which are powered by gas turbine engines capable of reaching 30 knots.

They are equipped with an Oto Breda 127 mm cannon, vertical launch system (VLS) Mk 41 for Evolved Sea Sparrow Missile (ESSM), Standard Missile and Harpoon Missiles. In addition the frigate has a Goalkeeper (rapid-fire gun), a Oerlikon 20 mm machine gun and a Mk. 46 Torpedo weapon system. The vessel also has the ability to carry a Lynx or NH-90 helicopter.

The second frigate to visit the capital is HNLMS Van Amstel, one of two multi-purpose M-class frigates. The frigate which is also known as the Karel Doorman class can be used for surface warfare and anti-submarine warfare. They also have their own air-defence capabilities.

The 122-metre vessels displace 3,300 tonnes and have a two Rolls Royce (Spey 1A) gas turbines delivering 29 knots. The class are equipped with an array of defence / attack armament to includes an Oto Melara 76 mm gun for surface and air targets, a Harpoon weapon system and a NATO Sea Sparrow Vertical Launch weapon system for use against air targets at close range. Like the De Zeven –class the M-class frigate is also capable of carrying a Lynx helicopter.

The Royal Navy's Type 22 frigate HMS Chatham (F87) which recently returned to UK waters after a seven month deployment on anti-piracy duties off Somalia, visited Dublin Port last weekend, writes Jehan Ashmore.

HMS Chatham was the lead vessel for NATO's 'Operation Ocean Shield' as part of a multi-national task force in the seas off the African state that in recent years has become notorious for piracy.

The frigate departed Dublin on Monday afternoon and set an easterly course off the Baily Lighthouse, but surprisingly the 5,300 tonnes vessel returned into the bay. HMS Chatham then crossed the bay towards Sandycove. From there the 148m vessel which has a draft of 6.7m veered in a south-easterly direction, to sweep past off the rocky outcrop, to the north of Dalkey Island and continued southbound off The Muglins.

In mid-November the frigate visited her namesake port on the Medway to mark the 20th anniversary since the vessel's commissioning at Chatham in 1990. The occasion was also the first time that such an event had taken place outside a Royal Navy establishment. 

Built in 1988, the vessel was launched from the Swan Hunter shipyard on the Tyne and is normally based in her homeport of Devonport, Plymouth.

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.
