#Kish50HSSgone - An exhibition in Dun Laoghaire celebrating the Kish Lighthouse 50th anniversary on Dublin Bay is currently on display, however the Stena Line HSS service to Holyhead which was withdrawn only last year has been outlived by the iconic lighthouse, writes Jehan Ashmore.

The venue for the Kish Lighthouse exhibition (until 21 November) is at the National Maritime Museum of Ireland located almost directly opposite of the present day iconic landmark of the LexIcon Library that overlooks the East Pier.

In addition the LexIcon as a new civic building has commanding sweeping views of the harbour, Dublin Bay and to the Baily Lighthouse on Howth Peninsula. Further offshore on the horizon stands the Kish Lighthouse all 31 metres high. The lighthouse replaced a lightship that likewise of the new lighthouse was manned until automated in 1992. The current character of the light exhibited has a range of 22 nautical miles.

Back onshore, Ireland’s most popular pedestrian pier, the East Pier is featured as part of the historic Pathé news footage (see above) as the Kish Lighthouse is ‘floated’ out of Dun Loghaire harbour from where the uniquely constructed structure was built. The design for the Commissioners of Irish Lights was of that of a concentric circular concrete tower based from similar yet smaller models in Sweden, and was towed from the harbour some seven nautical miles offshore to the Kish Bank.

The departing lighthouse structure under tow from the harbour even now looks futuristic and likewise to when I recall witnessing the first arrival of the Swedish owned yet Finnish built HSS Stena Explorer. She made her debut just over three decades later after the lighthouse began service. The fast-ferry was sold this Autumn and is currently under tow while bound for a new career in Turkey, which as previously reported leads to query her future role? given that her owners operate 'floating' generating powerships!

Returning to the Pathé news reel, (some 30 seconds in) on the left side of the screen can be seen white buildings on the East Pier. They belonged to the harbour's first albeit temporary car-ferry terminal (another controversary! of the time). The facility was completed a year before the installation of the Kish Lighthouse in 1965. The terminal's appearance comprised of metal constructed halls more akin to factory warehouses! In fact the terminal building extended almost the entire width of the East Pier!... click for Photo.

It was during that year's summer that the introduction of the first roll-on roll-off 'carferry' on the Dun Laoghaire-Holyhead route begin service with a resounding success. The traditional 'mail-boats' maintained a year-round service based out of the Carlisle Pier. From there cars were crane-hoisted on board for many years, however tourism interests lobbied for a carferry service from the early 1960's.

This led to Dun Laoghaire Harbour’s first ferry terminal with a ro-ro linkspan that protruded from the East Pier Jetty. The facility was inaugurated by the Irish-Walsh route’s first purpose built car-ferry, the unimaginatively named but pioneering Holyhead Ferry 1. The new carferry was delayed entering service from her builders and instread the English Channel based Normannia opened the seasonal 'car' service. 

Normannia originally a passenger-ferry had been converted to carry cars was eventually replaced by Holyhead Ferry 1 that season. The Scottish built stern-only carferry loaded and offloaded vehicles while berthed at the East Pier linkspan, though this structure located off the jetty has long since been demolished.

The berth at this East Pier Jetty until recent years has long been associated with the customary visits of Irish Naval Service patrol ships, however this part of the pier is to undergo a reincarnation. That been as previously reported on Afloat, the Dun Laoghaire Harbour Company’s ‘Urban Beach’, a €2.5 million heated floating swimming pool inspired by the 'Badeschiff' in Berlin.

The project will involve a converted river barge at the East Pier following last year’s planning permission granted by An Bord Pleanála. The planning authority is to make a decision (see SOS protest) following oral hearings into DLHC’s single €18m cruise-berth in January 2016. DLHC cited should a suitable ferry operator be found it would not be until 2016 and that the Ireland-Wales service like the HSS service would be run on a season-only basis.

Seven operators responded earlier this year following an invite from DLHC for those expressing an interest to operate such a service, however this would not involve the idle Stena HSS berth at the terminal on St. Michaels Wharf. The same site dates back to the original purpose-built terminal dating from 1969 that replaced the facility on the East Pier.

Dun Laoghaire Harbour's only remaining ferry berth (last used several years ago by a smaller Stena 'Lynx' fast -ferry) is also located on the Wharf. This linkspan facility adapted from a conventional carferry berth was also in use by Stena tonnage until the early 1990's.

The future role of the St. Michaels Wharf ferry terminal is now centre stage given DLHC's proposed cruise-berth is to connect to the terminal's former HSS vehicle marshalling bays where cruise passengers would use awaiting coaches and taxi's. At the same time, there are plans at the same site put forward by the Dun Laoghaire Combined Clubs for a National Watersports Centre. 

Remnants of another ro-ro linkspan on Carlisle Pier still visible, ceased use in 1996 when Stena Adventurer (ex. Stena Hibernia / St. Columba of Sealink British Rail ) was replaced by the Stena HSS. The revolutionary fast-ferry was also a pioneering venture on the route for almost two decades.

The old ro-ro's concrete berth's structure with operations hut can be seen from the Royal St. George Yacht Club albeit the corresponding linkspan is gone should you peer through the railings that bound the pier's car-park.

This part of the Carlisle Pier is the closest the public can access when small sized cruiseships have berthed since the trade returned to the harbour in recent years. While larger deeper draft cruiseships anchor offshore, notably the last caller of this season was the newbuild Mein Schiff 4.

#KishLight@50- The Commissioners of Irish Lights today welcomed the visit of President Michael D Higgins and Mrs. Sabina Higgins to join the Board and staff to say 'Happy Birthday' as the Kish Lighthouse celebrates 50 years of service on the 9th November 2015.

Imagine what that means.

How many millions of passengers have watched the Kish fade over the horizon as they emigrated to Britain and beyond? How many have watched its welcoming flash guide them safely back home to Ireland?

95% of everything we use arrives and leaves by sea. Imagine the cargoes made safe by the Kish Light. The agricultural products, the machinery, the building materials, the household goods, the cars, the clothes; every single staple of our lives has passed the great guiding lighthouse on the Kish.

As a witness to social history the Kish has seen significant change. Containerisation has changed the ships and crews, air travel has changed the passenger numbers, fuel costs have allowed it witness the growth and subsequent decline of fast vessels such as Jetfoil and HSS. (See, Afloat's latest report on the former Stena Explorer currently heading for Turkey).

Consider the lives of the Lighthouse Keepers who lived on the tower until automation in 1992.

The Kish Lighthouse is not just a seamark but a very significant engineering landmark of its day. The lighthouse replaced a lightship which was one of a series of such vessels that marked the Kish Bank since 1811 – meaning that there has been a continuous light on the Kish for the 204 years.

#KIshLight@50 - One of Ireland’s most famous and unique lighthouses, the Kish Bank Lighthouse off Dublin Bay, celebrates its 50th anniversary today having been commissioned into service on 9th November 1965, writes Jehan Ashmore.

At 31m high, the lighthouse which is an iconic symbol on the Dublin Bay horizon replaced a lightship understood to have been the Gannet. On that same day five decades ago the lightship was withdrawn and the first flashes were exhibited by the new lighthouse.

A light to ward off seafarers from the dangerous sands of the Kish Bank can be first traced back to more than 200 years ago. This earliest light was exhibited on 16 November 1811 which involved several small vessels of just over 100 tonnes each to share duties. Crews were tasked in using a floating light.

For the last half-century, the Kish Lighthouse located some 7 nautical miles offshore of Dun Laoghaire Harbour, from where the structure was built, has continued to provide the role as an important aids to navigation to seafarers.

In addition the Kish Lighthouse, albeit of Swedish design represents a significant moment in Ireland’s marine engineering heritage given the majority of the work was carried out by an Irish labour force.

The design origins of the Kish Lighthouse began in the early 1960’s as the Commissioners of Irish Lights (CIL) considered using a platform similar to those used as oil rigs for lighthouses purposes. Stemming from this nine engineering firms were asked to submit design tenders for such a lighthouse. The Swedish firm of Messrs Christiani & Nielsen Ltd was selected.

Their design was not for a steel platform like an oil rig but a concrete structure designed to last for at least 75 years and based on the lines of similar yet smaller models from Sweden. The reason for a larger version for the Kish Bank was so to cope with the rougher sea conditions of the Irish Sea.

Construction took place near St. Michaels Wharf (site of the former Stena HSS ferry terminal). Built of reinforced concrete in the form of a circular caisson, from within a concentric design included from a tower that together was floated out by tugs from Dun Laoghaire Harbour on 29 June 1965 (see footage above).

The lighthouse structure was sunk onto the Kish Bank from where a level platform of stones had previously been prepared by divers and buoyed by the Commissioners of Irish Lights tenders. The operation to raise the tower which was telescoped to its fullest extended height took almost a month to complete on 27 July.

For just over a quarter century, the white tower with its distinctive red band and topped off with a helicopter pad, was manned with a crew of three. The tower is a self-contained unit of 12 floors for keepers' quarters, storage, a generator, radio equipment and of course the lantern.

Crew were transferred in rough weather to the lighthouse by winching in a cradle pod from the lighthouse tender ship. Such practices were discontinued as the lighthouse notably was automated in 1992, ending another chapter in the history of Irish lighthouse-keepers.

Over the years the character of the light has varied. Currently the character is: Fl (2) 20s. 24 hour light which gives a range of 22 nautical miles. The actual height of the light at MHWS is of 29 metres.

Occasionally, the CIL’s aids to navigation tender, ILV Granuaile can be seen departing her homeport of Dun Laoghaire Harbour to carry out maintenance duties on the Kish Lighthouse.

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.
