#FERRY NEWS-A month from today sees the resumption of fast-ferry sailings on the Dun Laoghaire-Holyhead route, operated by Stena Line's HSS Stena Explorer, writes Jehan Ashmore.

The 120 minute central-corridor route closed in mid-September due to consistent high operating costs in recent years. This led to the withdrawal of the fuel-thirsty HSS craft which is powered by four gas-turbine engines.

In addition most of the route's turnover was generated in the high season months, leaving the remaining months unsustainable. As such the company decided to make the service as a seasonal-only operation. To read a previous report of the closure click HERE.

The ending of the year-round-service was the first major break to the route since the introduction of the pioneering HSS Stena Explorer in 1996 which in turn had replaced conventional tonnage. The Finnish built craft was the first of a trio of sisters commissioned for Stena Line and only this vessel remains in service for the operator.

Also operating on the route in recent years was the smaller fast-ferry craft Stena Lynx III which had served several high and low seasons, though she  will not be joining her larger fleetmate. The Tasmanian built Incat fastcraft was sold last year to South Korean interests as previously reported on Afloat. ie

Meanwhile the company's Dublin-Holyhead route is maintained by conventional tonnage vessels, Stena Adventurer and Stena Nordica which operate the 3 hour 15 minute service.

Irish Sea fast-ferry Stena Lynx III (1996/4,113grt) which has been laid-up in Dun Laoghaire Harbour since last month has been sold to interests in South Korea. Renamed Sunflower 2 and flying the flag of the Far-Eastern nation, she departed yesterday afternoon on a delivery voyage expected to take around twenty-five days, writes Jehan Ashmore.
The Dublin Port pilot cutter Camac was in attendance as the 650 passenger/153 vehicle fast-ferry departed at 16.20hrs. She is re-registered in Busan, South Korea's second largest city, located in the south-east, where she is to operate to the island of Jeju off the country's south-west coast.

Sunflower 2 is to make bunker calls on the repositioning voyage, firstly in Valletta, Malta before she transits the Suez Canal to the Red Sea port of Jeddah, Saudi Arabia and Columbo, Sri Lanka. From there she transits the Strait of Malacca then through the South China Sea followed by the East China Sea before finally entering the Strait of Korea to her homeport of Busan.

Since 1999 she has served Stena Line's fast-ferry high-season Rosslare-Fishguard route sailings taking 1 hour 50 minutes in tandem with conventional ferry Stena Europe (1981/24,828grt) which currently maintains the year-round 3 hours 30 minutes route. It is believed that Stena Line will not be operating high-season fast-ferry services in 2012.

Prior to her Dun Laoghaire departure, her South Korean crew have been preparing the craft over the last three weeks. Notably there was the removal of all Stena Line corporate livery markings on the hull. Her new name and port of registry were painted at the stern though she retained her original name at the bow which included both symbols of an Irish shamrock aptly to starboard (green) and the Welsh dragon to port (red) to reflect her Irish Sea southern corridor route.

Stena Lynx III departing Dun Laoghaire last year, note her starboard 'Shamrock' at the bow.

In recent years on the St. Georges Channel route she was marketed as the Stena 'Express'. Her final sailing this year was 4 September and three days later she docked Dun Laoghaire at St. Michaels Pier. On the adjacent berth which is designed specifically for and only capable of accommodating the HSS 1500 class fast-ferries.

Stena Lynx III also ran several shoulder season stints on the Dun Laoghaire-Holyhead route with the HSS Stena Explorer (1996/19,638grt) only running during the busier summer months. During this summer all sailings were maintained by HSS Stena Explorer until the route became a seasonal-only service for the first time this year when the last sailing took place in mid-September. The HSS remains in layover for the winter in Holyhead at her dedicated berth. The route is due to re-open in April or May.

The 35 knot Stena Lynx III was launched from fast-ferry catamaran specialists InCAT Pty based in the Tasmanian capital of Hobart. Early in her career the 81m wave-piercing catamaran (WPC) craft served Dover-Calais followed by two seasons between Newhaven-Dieppe when renamed P&O Elite for joint operators P&O Stena Line.

Her predecessors the WPC InCat 74m Stena Sea Lynx, became the first car-carrying catamaran to operate Dun Laoghaire-Holyhead sailings in 1993. The pioneering water-jet propelled craft was replaced in subsequent years by the larger InCAT 78m Stena Lynx II.

She was replaced in 1996 when the revolutionary four gas-turbine engine water-jet propelled HSS Stena Explorer was introduced. A further two sisters of the HSS 1500 class (High-speed Sea Service) were completed by Finnyards in Rauma.

At 13.07hrs Stena Line's HSS 1500 fast-craft ferry HSS Stena Explorer pulled away from her berth for the last time this year on the Dun Laoghaire Harbour-Holyhead route, as she headed for the harbour mouth several crew members waved from the stern to shore-based colleagues on the link-span, writes Jehan Ashmore.
Only yesterday, sailings on the daily single-round trip operated route had to be cancelled due to adverse weather conditions on the Irish Sea caused by the tail end of Hurricane Katia. The decision with today's closure was made well in advance and comes as no surprise as the Stena Explorer (1996/19,638grt) "has traded at a financial loss for several years" according to her owners Stena Line. Around 53 staff in Dun Laoghaire will be affected by the decision.

The core reason to withdraw the HSS on the 120-minute route which is not to re-open until the 2012 season, rests with the high operating costs of the fuel-thirsty fast-ferry which is powered by four gas-turbine engines. In addition the route's generated most of its turnover during the period May-September, leaving the remaining months unsustainable, as such the company wants the route to be seasonal-only in the long-term.

Passengers and freight customers will instead need to use the company's other Dublin Bay route between Dublin Port and Holyhead. The 3 hour 15-minute central corridor route is served by two ro-pax vessels, Stena Adventurer (2004/43,532 grt) and Stena Nordica (2000/24,206 grt) which operate to a year-round schedule, for times click HERE.

What is not certain is the precise date for resumption of Dun Laoghaire-Holyhead services as Stena Line have only indicated that they hope to reopen in April or May nor it is outlined as to what type of fast-craft would operate the route next year.

With today's break in service for at least the next six months, this is the most significant absence of the revolutionary HSS (High Speed Sea Service) 1500 fast-ferry which made her official maiden voyage on the route from Dun Laoghaire on 10th April 1996. The only other notable occasions when the HSS was off-service was for the short spells to allow for annual dry-docking, refit, repairs or when the route in recent years was partially operated by Stena Lynx III.

The 1500 referred to the number of passengers the Stena Explorer could accommodate. She was the first of the three Finish-built HSS 1500 catamaran vehicle capable carrying craft to enter service on three routes from the UK. The next sister completed HSS Stena Discovery entered service in the same year between Harwich-Hook van Holland and the final of the trio HSS Stena Voyager entered the Belfast-Stranraer route in 1997. Several years ago the HSS ceased operating on the Dutch route and the HSS currently serving on the North Channel is due to be replaced by conventional ferries in mid-November as previously reported on Afloat.ie, to read more click HERE.

On the Dun Laoghaire-Holyhead service the HSS enjoyed the boom years, and at its peak there were five daily round trips. From 2006 onwards the routes fortunes began to decline due to the ending of duty-free sales, competition from low-cost airlines, and the increasing cost of fuel.

In order to stave off further losses, a series of cost cutting measures were implemented over the next five years. Firstly the sailing frequency was reduced then the passage times were increased to reduce fuel consumption at the expense of faster crossings. In addition the company resorted to withdrawing the Stena Explorer during the shoulder months surrounding the summer and as previously mentioned these sailings were covered by the Stena Lynx III.

When the Stena Explorer returned for the summer months, the Stena Lynx III switched to her normal high-season spell on Rosslare-Fishguard sailings in tandem with regular route vessel Stena Europe. This year she served as usual on the St. Georges Channel route with the last high-season sailing completed on 4 September.

Stena Lynx III remained initially at Fishguard until making a repositioning voyage to Dun Laoghaire via the Kish Lighthouse last Wednesday. She berthed adjacent to the now disused HSS berth link-span on St. Michaels Wharf. The Tasmanian built craft has spent previous winter layover periods in Dublin and last year in Dun Laoghaire whereas the Stena Explorer is expected to do so in her home port of Holyhead.

At the neighbouring Carlisle Pier, the former terminal where numerous steam-packets, 'mailboats' and the conventional Sealink/British Rail car-ferries served (the last being the Stena Adventurer better known as St. Columba built in 1977) there are plans for a national diaspora museum.

The centrepiece landmark building would form as part of the masterplan proposed by the Dun Laoghaire Harbour Company as part of a concerted effort to offset the reduced role of ferry operations. The masterplan is also to attract cruiseship business amongst other proposals envisaged.

Holidaymakers now have the added option of  fast-ferry sailings on Stena Line's Rosslare-Fishguard port route which is to resume tomorrow, writes Jehan Ashmore.
The high season service is operated by the fast-ferry Stena Lynx III which is marketed as the Stena 'Express' . The summertime service runs between 1 July - 4 September and the fast-ferry is scheduled to take 120 minutes for the crossing.
Stena Lynx III has a capacity for over 600 passengers and 120-cars, to see a virtual tour of the wave-piercing catamaran craft click HERE. Measuring 81m long the 4,113 gross tonnes craft was built in 1996 by fast-ferry specialists InCat in Hobart, Tasmania. In recent years she maintained sailings between Dun Laoghaire-Holyhead when the HSS Stena Explorer was temporily taken off service.

In addition to the 'Express' service the St. Georges Channel route is served by the year-round operated conventional ferry, Stena Europe (1981/24,828 grt). The 1,386 passenger / 564-vehicle ferry recently underwent a £2m refurbishment and takes a more leisurely passage time of 3 hours 30 minutes.

Fast-ferry Stena Lynx III departed Dun Laoghaire for Fishguard Harbour on a repositioning voyage today, writes Jehan Ashmore.

The 80m craft built in Hobart, Tasmania is due to dock at the Pembrokeshire port this afternoon in advance of seasonal sailings on Stena Line's Fishguard-Rosslare.The Stena 'Express' fast-ferry service is to resume in just over a fortnight's time. Sailings are scheduled to a daily single round trip between 1 July-4 September.

The 627 passenger / 120 car capacity fast-ferry will operate in tandem with the year-round operated conventional ferry-service served by the Stena Europe. Passage times are 120 minutes for the fast-ferry service while the Stena Europe takes 3 hours 30 minutes to sail across the St. Georges Channel.

In the same week that the fast-ferry takes up summer sailings from Fishguard, the small French flagged cruiseship Le Diament is to make the first of three calls in July and once in August.

The motoryacht-like vessel which can accommodate 226 passengers is the first cruise caller of the season and is run by the only French-owned cruise operator Compagnie De Iles Du Ponant.

Stena's Southern Sailings

Sailings on Stena Line's Rosslare-Fishguard port route remain for freight-users only until the passenger ferry returns from essential maintenance this week, writes Jehan Ashmore.
The passenger ferry Stena Europe is currently in dry-dock at the A&P Group's Falmouth facility and is scheduled to resume normal service with the first sailing at 14.30hrs from Fishguard on Thursday 7th April. The corresponding first outbound sailing from Rosslare is on the same day with the 21.15hrs sailing.

In the meantime freight-only ferry Stena Seafarer is operating the St. Georges Channel route having arrived at Rosslare on a repositioning voyage from Belfast on 29th March.

Stena Seafarer (1975 / 10,957grt) was one of a trio of freight-ferry sisters that served the Larne-Fleetwood port route until its closure in December. Like her sisters Stena Leader (1975 / 12,879grt) and Stena Pioneer (1975 / 14,426grt) they were built at the West German shipyard of J.J. Sietas in Hamburg.

Stena Seafarer's sisters remain laid-up in Belfast and with each vessel over 35 years in service it would seem likely there are nearing the end of their careers, at least on the Irish Sea.  

To provide additional passenger capacity the Stena 'Express' fast-ferry service will return to the southern corridor route between 1 July-4 September. The high-season sailings as usual will be operated by the InCat built Stena Lynx III which is to operate a daily single round trip in tandem with Stena Europe.

HSS Sailings Resumed

This year's first ferry sailing of the HSS Stena Explorer from Dun Laoghaire to Holyhead was disrupted yesterday due to 'technical reasons'.
The HSS (High Speed Service) fastcraft was scheduled to depart Dun Laoghaire at 13.15hrs but the sailing was cancelled. Passengers booked on the 19,638 tonnes fastcraft were transferred to Stena Line's neighbouring Dublin-Holyhead route, to take last night's sailing instead.

The Stena Explorer had completed her first sailing from Holyhead yesterday morning, the fastcraft having departed the Welsh port at 10.00hrs.

Due to the technical difficulties, the Stena Explorer was not in a position to accommodate passengers on the return crossing, though the fastcraft did depart Dun Laoghaire 'light' (without passengers) at 18.45hrs for Holyhead.

The Stena Explorer resumed service with this morning's 10.00hrs sailing from Holyhead to Dun Laoghaire.

The re-introduction of the Stena Explorer is to provide greater capacity during the summer season compared to the smaller Stena Lynx III, which previously served the route until early January. The HSS will operate the two-hour route with a daily single round trip up to 13 Setember.

Stena Line's HSS fast-ferry the Stena Explorer will be re-introduced on its Dun Laoghaire to Holyhead route this Friday, writes Jehan Ashmore.

The HSS (High Speed Service) operated 19,638 tonnes craft will run between 1 April to 13 September to cope with the additional demand over the summer period.

A single daily round trip is scheduled with a 10.00 hours sailing from Holyhead and a 13.15 hours sailing from Dun Laoghaire. Passage time is 120 minutes (2 hours).

The HSS can 350 vehicles and with 1500 passengers, the craft can handle higher volumes of seasonal summer foot passengers compared to the last route serving vessel, the 4,113 tonnes Stena Lynx III. The return of the HSS service links in with those intending to make onward journeys from Dun Laoghaire's DART commuter rail service to Dublin city centre and beyond on the national rail network.

Up to early January the route had been served by the Stena Lynx III which remains moored alongside Dun Laoghaire's St. Michaels Wharf. The craft which can take 627 passengers and 120 cars and marketed as the Stena 'Express' is to resume high season sailings starting in July between Rosslare-Fishguard.

In total the company carries over two million passengers on its four Irish Sea routes each year. An additional route between Belfast-Liverpool (Birkenhead) was taken over by the Swedish owned ferry company from DFDS Seaways late last year, is subject to regulatory clearance.

Until such clearance has been granted, this route will be operated separately from all other Stena Line routes. In the meantime the company advise until further notice to make bookings which will remain acceptable through the use of the DFDS website.

With just over a fortnight to go to resumption of Stena Line's Dun Laoghaire-Holyhead fast-craft sailings on 1 April, the route to Wales is to see the larger HSS Stena Explorer return instead of Stena Lynx III, writes Jehan Ashmore.
It was originally planned that the 4,113grt 'Lynx' craft would start the season while the 19,638grt HSS (High Speed Service) fast-craft would take over in June for the summer months.

According to Stena Line over 70% of its passengers business is carried by the HSS Stena Explorer in the high season. It is felt that the 1996 Finnish built fast-craft is better suited for the service due to a loyal customer base which was reflected by repeat bookings and their preference of the HSS craft on the 120 minute (2 hour) route.

A daily single round trip is scheduled with sailings from Dun Laoghaire to Holyhead departing at 13:15hrs. The corresponding sailing from the Anglesey port departs at 10.00hrs and arrives at the Irish port at 12 noon. Sailings will operate through the summer until 13 September.

From there on Stena will make a decision as to its continuing schedule, though it is widely believed that the prospects of the fuel-thirsty, expensive to run HSS fast-craft service are likely to be at an end of an era.

Last month negotiations over the core issue of harbour fees were held between Stena Line and Dun Laoghaire Harbour Company. It is understood that the annual fee of €6.5m was dropped to €2m. The board of the harbour company has given a 'conditional green light' of a new ferry contract to Stena Line to run the service for the next two years with an option of a third year.

The service closed for its seasonal break earlier this year on 5 January with the 'Lynx' going into temporary lay-up at Holyhead's inner harbour to join the HSS Stena Explorer. The HSS had been 'wintering' at the port since September sailings were taken over by the Lynx.

Earlier this month the Stena Lynx III came to Dun Laoghaire to continue her lay-up period. The 1996 Tasmanian built craft will stay there before resuming seasonal sailings between Rosslare-Fishguard in tandem with the conventional ferry Stena Europe.

In the meantime the craft is berthed at the harbour's two-berth ferry terminal at St. Michaels Wharf. The HSS berth is only designed for this type of fast-craft whereas the other berth now occupied by the Lynx was built originally for conventional ferries but was re-configured last year to suit the fast-craft.

Fast-ferry catamaran Stena Lynx III is to resume offpeak sailings on Wednesday (15 September)
on the Dun Laoghaire-Holyhead route, writes Jehan Ashmore.
The 'Lynx' had spent the high-season on St. Georges Channel in tandem with conventional
ferry Stena Europe on the Rosslare-Fishguard route. Prior to then the Lynx craft also served Spring
sailings on the Dun Laoghaire-Holyhead service as a replacement vessel of the HSS Stena Explorer.

The reasoning for the change of vessels on the central Irish Sea route during the Spring and
forthcoming Autumn /Winter seasons is a cost-cutting measure on behalf of operators Stena Line.
The larger HSS craft is becoming increasingly more expensive to run using fuel thirsty gas-
turbine engines, compared to the smaller capacity Stena Lynx III, which can be used instead
during the quieter months.

Stena Explorer is to be withdrawn with the last round trip sailing tomorrow (14 September)
departing Holyhead at 10.00hrs and arriving at Dun Laoghaire at noon. Correspondingly the HSS departs
the Irish port at 13.15hrs and returns to the Welsh port two hours later.

On the following day (15 September) the Stena Lynx III will make her first outbound departure
from Holyhead at 10.00hrs arriving Dun Laoghaire at 11.50hrs. After a turn-around period in the Irish port
the Lynx departs at 13.15hrs with an arrival to the Anglesey port at 15.05hrs.

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.
