#WATERWAYSIRELAND – In its first notice to mariners of 2012 Waterways Ireland has published a list of the most important aspects of waterways regulations for boat owners. It includes the Registration of Vessels, Canal Permits, Events Held on the Waterways, Berthing in Public Harbours and many more useful reminders for the use of the waterways this coming season. Full details of the 'special notice' from the Inspector of Navigation Charles J Lawn Lt Cdr (rtd) is below:

Registration of Vessels

All vessels using the Shannon Navigation and the Erne System must be registered. Only open undecked boats with an engine of 15 horsepower or less, on the Shannon Navigation, and vessels of 10 horsepower or less, on the Erne System, are exempt.

Canal Permits

All vessels using the Grand and Royal Canals and the Barrow Navigation must have a current valid Permit displayed before being navigated or moored.

Events Held on the Waterways

All organised events taking place on the waterways must have the prior approval of Waterways Ireland. Application forms for this approval and the associated indemnity form may be had from the Inspectorate offices.

Berthing in Public Harbours

On the Shannon Navigation and the Shannon-Erne Waterway craft may berth in public harbours for five consecutive days or a total of seven days in any one month during the period 1 April to 31 October. This also applies in Clondara / Richmond Harbour on the Royal Canal and in Shannon Harbour and the Tullamore Spur Line on the Grand Canal.

On the Erne System no vessel may berth at a public mooring for more than 48 hours without a four hour intermission.

Pump Out Berths

Masters of vessels should note that it is not permitted to berth at pump out stations.

Smart Cards

Waterways Ireland smart cards are used to operate certain locks, to access the service blocks and to use the pump-outs along the navigations. Electrical Power is also available using smart cards at a limited number of public mooring locations, including Scarriff, Shannonbridge, Garrykennedy, Carrick and Ballina (Tipperary). Operating instructions are displayed in English, French and German.

Passenger Vessel Berths

Masters of vessels should not berth on passenger vessel berths where it is indicted that an arrival is imminent. Passenger vessels plying the navigations generally only occupy the berths to embark and disembark passengers and rarely remain on the berths for extended periods or overnight.

Lock Lead-in Jetties

Lead-in jetties adjacent to the upstream and downstream gates at lock chambers are solely for the purpose of craft waiting to use the lock and should not be used for long term berthing.

Vessel Wash

Vessel wash, that is, the wave generated by the passage of the boat through the water, can sometimes be large, powerful and destructive depending on the hull shape and engine power of the vessel. This wash can be detrimental to other users of the navigation when it strikes their craft or inundates the shoreline or riverbank. Masters are requested to frequently look behind and check the effect of their wash particularly when passing moored vessels, on entering harbours and approaching jetties and to be aware of people fishing or recreating on the riverbank.

Speed Restriction

A vessel or boat shall not be navigated on the Shannon Navigation at a speed in excess of 5 kph when within 200 metres of a bridge, quay, jetty or wharf, when in a harbour or canal or when passing within 100 metres of a moored vessel or boat.

Vessels navigating the Shannon-Erne Waterway should observe the general 5 kph speed limit which applies along the waterway. This is necessary in order to prevent damage to the banks caused by excessive wash from vessels.

Vessels navigating the Erne System should observe the statutory 5 kt / 6mph/10kph speed limit areas.

Bank Erosion

Narrow sections of all the navigations are particularly prone to bank erosion due to the large wash generated by some craft. Masters are requested to be vigilant and to slow down to a speed sufficient to maintain steerage when they observe the wash of their craft inundating the river banks.

Unusual Waterborne Activity

Unusual waterborne vessels may be encountered from time to time, such as, hovercraft or amphibious aircraft / seaplanes. Masters of such craft are reminded to apply the normal "Rule of the Road" when they meet conventional craft on the water and to allow extra room to manoeuvre in the interest of safety.

Sailing Activity

Mariners will encounter large numbers of sailing dinghies from late June to August in the vicinity of Lough Derg, Lough Ree and Lower Lough Erne. Vessels should proceed at slow speed and with due caution and observe the rules of navigation when passing these fleets, as many of the participants are junior sailors under training.

Rowing

Mariners should expect to meet canoes and vessels under oars on any part of the navigations, either recreating, in training or in competition but more so in the vicinity of Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Masters are reminded to proceed at slow speed and especially to reduce their wash to a minimum when passing these craft as they can be easily upset and swamped due to their very low freeboard and always be prepared to give way in any given traffic situation.

Canoeing

Canoeing is an adventure sport and participants are strongly recommended to seek the advice of the sport's governing bodies i.e The Irish Canoe Union and the Canoe Association of Northern Ireland, before venturing onto the navigations.

Persons in charge of canoes are reminded of the inherent danger to these craft associated with operating close to weirs, sluice gates, locks and other infrastructure particularly when rivers are in flood and large volumes of water are moving through the navigations due to general flood conditions or very heavy localised precipitation e.g. turbulent and broken water, stopper waves. Shooting weirs is prohibited without prior permission of Waterways Ireland.

Portage is required at all locks, however, a heavily laden canoe may be put through a lock unmanned provided it is attended with a head and stern line.

Fast Powerboats and Personal Watercraft (Jet Skis)

Masters of Fast Powerboats (speed greater than 17kts) and Personal Watercraft (e.g.Jet Skis) are reminded of the inherent dangers associated with high speed on the water and especially in the confines of small bays and narrow sections of the navigations. Keeping a proper look-out, making early alterations to course and /or reducing speed will avoid conflict with slower vessels using the navigation.

Age Restrictions

In the Republic of Ireland you have to be at least 16 years of age to operate a PWC e.g Jetski and 12 years of age or over to operate a vessel with more than a 5 hp engine.

Prohibition on Swimming

Swimming in the navigable channel, particularly at bridges, is dangerous and is prohibited due to the risk of being run over by a vessel underway in the navigation.

Towing Waterskiers, Wakeboarders, Doughnuts etc

Masters of vessels engaged in any of these activities are reminded of the manoeuvring constraints imposed upon their vessel by the tow and of the added responsibilities that they have to the person(s) being towed. These activities should be conducted in areas which are clear of conflicting traffic. It is highly recommended that an person additional to the master be carried to act as a "look-out" to keep the tow under observation at all times.

Lifejackets and Personal Flotation Devices (PFD's)

Lifejackets and PFD's are the single most important items of personal protective equipment to be used on a vessel and should be worn especially when the vessel is being manoeuvred such as entering / departing a lock, anchoring, coming alongside or departing a jetty or quayside.

In the Republic of Ireland all persons on board any craft of less than 7m (23 ft) must wear a lifejacket or PFD while on board an open craft or on the deck of a decked craft that is not made fast to the shore. This requirement also applies to Personal Watercraft Craft and any vessel or object being towed e.g. waterskier, wakeboarder, doughnut, banana etc.

Danger Area

The attention of mariners is drawn to the Army Firing Range situated in the vicinity of buoys No's 2 and 3, on Lough Ree in the Shannon Navigation.

Shannon Navigation, Portumna Swing Bridge Tolls

No attempt should be made by Masters' of vessels to pay the bridge toll while making way through the bridge opening. Payment will only be taken by the Collector from Masters when they are secured alongside the jetties north and south of the bridge.

Shannon Navigation, Abbey River and Sarsfield Lock, Limerick

The attention of all users of this stretch of the Shannon Navigation is drawn to the published notices regarding navigation. Users are advised to contact the ESB Ardnacrusha Hydroelectric Power station before commencing their passage to ascertain how many turbines are currently running. It is advised NOT to undertake a voyage if more than one turbine is operating, due to the increased velocity of flow in the navigation, which can be dangerous. This situation may also arise when flood conditions prevail. Further, passage of Sarsfield Lock should be booked on 353-87-7972998, on the day prior to travel and it should be noted also that transit is not possible two hours either side of low water.

Lower Bann Navigation

The attention of all users is drawn to the "Users Code for the Lower Bann", in particular to that section covering "Flow in the River" outlining the dangers for users both on the banks and in the navigation associated with high flow rates when the river is in spate. Canoeists should consult and carry a copy of the "Lower Bann Canoe Trail" guide issued by the Canoe Association of Northern Ireland.

Overhead Power Lines (OHLP)

The attention of all is drawn to the dangers associated with overhead power lines in particular sailing vessels, sailing dinghys and workboats with cranes. Vigilance is required especially in the vicinity of slipways and dinghy parks, while voyage planning is a necessity in order to identify the location of overhead lines crossing the navigations. If the vessel or its equipment comes in contact with an OHLP, do NOT attempt to move the equipment or a person if either is still in contact with, or close to, the OHLP. The conductor may still be alive or re-energise automatically. Maintain a 5 m clearance, if possible, and prevent third parties from approaching you or your vessel because of the risk of arcing. Contact the Coast Guard for assistance. Fishermen are also reminded that a minimum ground distance of 30 metres should be maintained from overhead power lines when using rod and line.

Submarine Cables and Pipes

Masters of vessels are reminded not to anchor their vessels in the vicinity of submarine cables or pipes in case they foul their anchor or damage the cables or pipes

Aids to Navigation – Shannon Navigation - Recognition

Masters should consult Waterways Ireland Marine Notices to inform themselves of the roll-out of the change over from the colour black to green for starboard hand marks. Topmarks remain the same i.e square on starboard and circular on port marks. White arrows on markers indicate the safe water side of the mark.

Caution to be Used in Reliance upon Aids to Navigation

The aids to navigation depicted on the navigation guides comprise a system of fixed and floating aids to navigation with varying degrees of reliability. Therefore, prudent mariners will not rely solely on any single aid to navigation, particularly a floating aid to navigation. With respect to buoys, the buoy symbol is used to indicate the approximate position of the buoy body and the ground tackle which secures it to the lake or river bed. The approximate position is used because of the practical limitations in positioning and maintaining buoys in precise geographical locations. These limitations include, but are not limited to, prevailing atmospheric and lake/river conditions, the slope of and the material making up the lake/river bed, the fact that the buoys are moored to varying lengths of chain, and the fact that the buoy body and/or ground tackle positions are not under continuous surveillance. Due to the forces of nature, the position of the buoy body can be expected to shift inside and outside the charted symbol. Buoys and perches are also moved out of position by those mariners who use them to moor up to instead of anchoring. Further, a vessel attempting to pass close by always risks collision with a yawing buoy or with the obstruction that the buoy or beacon / perch marks.

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.
