The Marine Casualty Investigation Board (MCIB) has said that a training session which went wrong on the river Corrib and resulted in the loss of two competitive rowing craft “posed a threat of death or serious injury” to those involved.

Fortunately, no lives were lost in the incident which occurred on January 14th, 2023, but the crew in two University of Galway rowing boats which were swept towards the Salmon Weir were novices with minimal experience.

New safety recommendations have been issued to eight rowing clubs after the MCIB identified that patterns of risky behaviour had become “normalised” and posed a threat to safety.

The incident occurred as University of Galway boats were approaching the end of their trip and saw other boats from Coláiste Iognáid heading upriver towards them.

One Coláiste Iognáid rowing boat with nine school teenagers was accompanied by a coach’s launch with two adults on board.

All craft steered towards the centre of the river to avoid a collision but this was in breach of “rules of the river”.

The vessels were now all in the river’s main current, with near-gale force westerly winds, and the two boats from the University of Galway Boat Club were swept towards the Salmon Weir where they capsized against safety booms.

The Coláiste Iognáid Rowing Club rowing craft subsequently capsized in reeds along the east bank, and all were rescued.

The MCIB criticised the university boat club for inadequate planning of a trip which took place in unsuitable weather and river conditions.

“A small craft warning and a gale warning were in effect from five hours before this rowing trip commenced, as winds of up to Force 8 were forecasted to occur along the western seaboard,” the report says.

It says the river conditions were also unsuitable for this rowing trip, as the river was in its normal winter spate conditions, with a high flow rate and a low water temperature.

“ These conditions existed for weeks before and after this casualty event. These conditions occurred in the vicinity of a significant weir, which the crews had to row past on both the outward and return legs,”it says.

“The high flow rate meant that the crews were unable to effectively control their boats, to change course away from the approaching weir. The low water temperature meant that the crews were exposed to the dangers of cold water immersion when their vessels capsized and they entered the water,”it says.

The MCIB notes that five incidents had occurred over the preceding two decades involving recreational boats at or above the weir.

The lack of a rescue vessel above the weir is also highlighted – the RNLI, Garda and Galway Fire and Rescue Service are located below the weir.

The hazards of lost or discarded fishing gear has been highlighted in a Marine Casualty Investigation Board (MCIB) report into the loss of a yacht off Baltimore, Co Cork, last June.

All five on board were rescued, after their yacht, named Inish Ceinn, snagged a large trawl net off the west Cork coast and was then swept onto rocks.

The 12.85 metre Sun Odyssey 42i had departed from Baltimore, Co Cork on June 6th, 2023 at 14.00 hours, for a short voyage to Cape Clear island.

It says the skipper was a well-qualified and experienced yacht master and diver, who had made this voyage on numerous occasions.

There were three other experienced persons onboard and one guest. The weather was moderate from the east and the yacht was taken out of Baltimore harbour and then headed west on the planned course towards Cape Clear.

The planned course was around 0.5 miles from the southern shore of Sherkin island and at around 14.30 hrs the skipper felt the yacht slow down rapidly and turn into the wind. Nothing could be seen in the water, so the engine was started and propeller engaged.

The report says vibration was felt and a burning smell was noticed, so the engine was shut down and the yacht was immobilised. However, wind and swell quickly pushed the yacht towards the rocks and it ran aground.

Four of the people onboard were able to get onto the rocks and the skipper sent a “Mayday “ message on the VHF radio. He then also got onto the rocks.

The report says that at this stage the skipper noticed the hull was fouled with a large trawl net. The RNLI Baltimore lifeboat came to the rescue, along with the Irish Coast Guard R115 helicopter from Shannon.

All five were evacuated from the rocks by the lifeboat and taken back to Baltimore.

The report says the yacht broke up and was lost, but there were no serious injuries and no pollution.

The report notes that the yacht had just completed a refit and was launched for trials on June 5th, 2023. These trials were completed successfully and the yacht and all equipment onboard was reported to be fully operational.

It says the yacht was in good condition and well outfitted with all modern safety and navigation equipment and no defects were identified that may have led to or contributed to the casualty.

It says the skipper was experienced and qualified to operate this yacht, and was also qualified as a yachting instructor. The bowman was also experienced, and the two relatives were regular sailors on yachts and small boats.

It says the crewmembers lack of experience was not considered a factor.

The weather had been recorded as easterly winds, force 3-4, with a slight swell and low waves on departure from Baltimore on a rising tide.

The report says the discarded trawl net was the root cause of this casualty.

“Had this fishing gear been properly discharged ashore or had it been reported and recovered if accidentally lost, this incident could have been prevented,”it says.

“ The source of the net cannot be established as it had no tags and there is no record of it having been reported to any Irish authority,”it says.

It notes that the net should have been marked with tags as required by EU No. 404/2011 Article 11.

“ If the net was lost from a fishing vessel in Irish waters, it should have been reported under Marpol Annex V to the flag state as defined by article 48 of EU Regulation No. 1224/2009 to enable a navigation warning to be issued,”it notes, but “there was no such warning issued for the area”.

It says the net may or may not have been from an EU registered vessel. If not an EU registered vessel, it is still subject to the International Convention for the Prevention of Pollution from Ships (MARPOL) which prohibits the deliberate dumping or discharge of fishing gear in the marine environment.

The report recommends that the Minister for Transport issue a marine notice which:

advises skippers of yachts navigating in areas which are known to have poorly marked fishing gear, lobster pots etc. that they should ensure the vessel's anchor is ready for immediate use;

advises fishers of the dangers of discarding nets from fishing vessels and sets out the obligatory regime on waste, plastics and recycling;

reminds fishers that if a net is lost, every effort must be made to recover it to enable it to be disposed of responsibly to shore reception facilities in accordance with the European Union (Port Reception Facilities for the Delivery of Waste from Ships) Regulations 2022 S.I. No. 351 of 2022;

reminds fishers that if a net cannot be recovered, the responsible authorities must be advised in accordance with Marpol Annex V so that a suitable navigational warning should be issued in the area where the net was lost;

reminds fishing vessel operators that they are required to record the discharge or loss of fishing gear in the Garbage Record Book or the ship's official logbook as specified in Regulations 7.1 and 10.3.6 of MARPOL Annex V. 2.2.2.

An incident where two crew members of a fishing vessel were asphyxiated during a fish tank cleaning operation could have had a “far more serious outcome” but for a number of factors, the Marine Casualty Investigation Board (MCIB) has said.

These factors included proximity and response of emergency services and some actions of the crew, along with the short distance to a hospital accident and emergency department, the MCIB says.

The incident occurred on the 24-metre fishing vessel Ardent, owned by Orpen Fishing Company Ltd of Castletownbere, Co Cork on October 31st, 2022.

It had left Port Oriel, Clogherhead to pair with FV Cisemair on fishing grounds in the Irish Sea, and was underway when the watch was transferred from the skipper to another crewmember, allowing the skipper to conduct the fish tank cleaning in preparation for the filling and cooling of the seawater within the tanks.

Both the skipper and crewmember were removing fish/waste product trapped in various locations within the fish hold/tank with limited airflow via the deck coaming access hatch.

The report says that the first “casualty” was overcome while passing below the tank centre boards. The second “casualty” was overcome while checking the condition of the first “casualty” who was lying on the tank floor.

The investigation says that a mixture of rotting fish and seawater was held within sections of the refrigerated sea water (RSW) system piping, cooler and valve chest below the shelter-deck over a prolonged period (approximately 150 hrs), at a temperature of approximately 15°C.

This produced dangerous levels of toxic gases that may have included: hydrogen sulphide, ammonia, hydrogen cyanide or carbon dioxide.

It says that both casualties were overcome by the toxic atmosphere when they lowered their heads into the “toxic pool”.

The vessel was turned around immediately, and returned to Port Oriel at a maximum speed of 9.4 knots before tidal constraints restricted access, while the Cisemar was asked to notify emergency services.

The vessel was brought alongside and secured with the aid of emergency services shore teams.

The two crew were treated in hospital, with one remaining in hospital for a number of weeks.

The MCIB recommends that the Minister for Transport should review the content of marine notices number 43 of 2016 and number 24 of 2009 and issue an updated marine notice warning crews on fishing vessels of the hazards associated with toxic gas generation and retention in RSW systems.

It makes other recommendations relating to enclosed space entry techniques, raising awareness of the correct use, maintenance and calibration of personal atmospheric monitoring systems, rescue equipment and recovery techniques.

It says crewmembers should participate in an appropriate drill and relevant codes of practice, and recommends the minister should review existing legislation on the requirement and application for onboard rescue breathing apparatus and training for confined spaces.

A breathing apparatus requirement should also apply to vessels with RSW systems installed,the report says.

The Marine Casualty Investigation Board (MCIB) has recommended that the Minister for Transport should consider introducing regulations specific to the installation and operation of articulated hydraulic deck cranes on fishing vessels.

The MCIB recommendation is one of a number issued in its report inquiring into a crush injury sustained by a crewman on board a fishing vessel off the Cork coast in November 2021.

Recommendations in relation to risk assessments, safety legislation, hazard warnings and training for use of articulated deck cranes are also published in the report.

The incident occurred on board the 21 metre-long fishing vessel Aquila which was fishing south of the Kinsale gas rigs on November 7th, 2021.

The vessel with five crew onboard had left the fishing port of Union Hall, Co Cork, the night before. Wind at the time was force three, westerly, with a moderate sea.

The wooden twin trawler was rigged for Danish seine net fishing

As the report states, “at approximately 12.00 hrs on the 7th November, the fishing vessel was at the fishing grounds and the crew were hauling the second haul of the day using the vessel’s net handling crane”.

It says that the crane’s hydraulic system “experienced a sudden loss of hydraulic oil pressure, causing the crane’s jib and power head to uncontrollably lower inboard trapping a crew member between the power head and the underside of the deck supporting the net drum”.

The crewman, who is from the Philippines and had been on the crew for two years, suffered crush injuries.

The vessel’s skipper contacted the Cork Coast Guard Radio (CGR) by VHF radio at 12.38 hrs, advising it of the incident and requesting a medical evacuation of the injured crewman.

It says that at approximately 15.00 hrs, the Irish Coast Guard helicopter R115 from Shannon airlifted the injured man ashore to Cork University Hospital (CUH) for medical attention.

The man was discharged from CUH on November 8th, and was passed fit to fly home. He returned to the Philippines to recover.

It says he recuperated, and has since returned to work as a fisher onboard an Irish registered fishing vessel.

The Marine Casualty Investigation Board (MCIB) has said that boarding and disembarking risk assessment and associated policies and procedures should “immediately be reviewed” after the serious injury of a diver working on salmon farms off the Galway coast.

The 33-year-old male contract diver, who was contracted by the salmon farm operators to inspect and maintain the salmon cages around Kilkieran Bay, Co Galway, sustained his injuries when he was pinned between two vessels during a transfer from one to the other off Ardmore pier on November 8th, 2022.

The incident occurred when a feed barge was making a rendezvous with a smaller vessel carrying five people, including two contract divers.

The injured casualty was brought back onboard the vessel and was subsequently airlifted to Galway University Hospital (GUH) where his injuries were assessed and included multiple fractures to the pelvis and fractured hip socket joints, the MCIB report says.

At the time of the interview with the MCIB in January 2023, the casualty was out of work, the report notes, and was walking aided by crutches.

Visibility was moderate or poor and winds on the day in question, November 8th 2022, were generally fresh force 5 to strong force 6 (mean wind speed 17 to 27 knots) and gusting up to 40 knots for a time.

In its analysis, the MCIB says that “means of safe access was not appropriate for transferring from one vessel to another and the practice of stepping over the side rails and onto the feed barge’s tyre fender became normalised”.

“ The prevailing conditions including the direction and height of the swell were contributing factors to this incident,”it says, as the licence required the vessel to operate in favourable weather.

There were missed opportunities during the purchase process to verify safe access to and from the vessels as both had safe means of access, but were not compatible when the vessels were moored alongside each other, the MCIB report says.

It says the operator's risk assessment failed to identify the deficiencies in vessel transfer operations and in particular with regard to third parties such as the contracted diver.

It says while the operation was identified by the operator under their safe systems of work, it was not authorised by the Marine Survey Office by way of a “permit to tender”.

In a series of recommendations to the salmon farm operator and owners of the two vessels on reviewing procedures, the MCIB also called on the Minister for Transport, in conjunction with his marine counterpart, to consider if it is “ appropriate or not” to issue a Marine Notice or similar, directed to the operators and those involved in marine aquaculture activities.

It recommends that the Marine Notice would remind operators and all involved of the dangers associated with boarding and transiting vessels at sea;

that operators have a safe system of work including suitable and sufficient risk assessments in place for operations carried out at sea including transfer of personnel onto fish cages and feed barges;

and that operators take steps to ensure that vessels transferring personnel at sea are properly licensed in accordance with passenger boat legislation and “permit to tender” for tendering operations as applicable.

The Marine Casualty Investigation Board has recommended that the Minister for Justice should consider carrying out an audit of the crewing arrangements of any fishing vessel or vessels to ensure non-EEA crew are compliant with the rules governing work permits.

It also says the minister should also ensure there is a robust system in place to ensure those given permits have a sufficient knowledge of English to be able to communicate with fellow crew on board Irish registered fishing vessels.

The MCIB recommendations have been made on foot of its investigation into the circumstances surrounding a serious leg injury sustained by a crew member on board a vessel, the John B, off the east coast in July 2020.

The incident occurred when the crew’s leg became trapped between the centre weight and the weight retaining cage at the stern of the vessel during a prawn fishing operation on July 17th, 2020.

The load was adjusted allowing the injured crew member to extricate his trapped leg from the grip of the centre weight, and other crew provided first aid.

The owners were informed, the vessel steamed to the nearest port, Howth, and the man was taken to Beaumont Hospital emergency department by private vehicle.

No external medical or emergency assistance was sought or requested by the skipper or the owners, the report notes.

The report concludes that no risk assessment for hauling the nets was shared with the crew, and some were employed without mandatory training.

It says the skipper was “inexperienced on the vessel and relied on his crew to recover the gear unsupervised, while he remained in the wheelhouse”.

It says evidence from the skipper asserting that the crew member had been warned about the dangers of standing on the weight while recovering the fishing gear, but continued to do so, “is not supported by any detail or any other evidence”.

It also says this assertion is denied by the casualty.

It says the design and layout of the fishing gear on this vessel was poor, making communication between the winch operator and deck crew difficult.

It says the winch operator could not see the crewmembers feeding the nets on to the reels, and clear lines of communication were also not in place, given that the winch operator could not see the crewmembers feeding the nets on to the reels.

“ Had there been a safe design and planned effective communications in place effective supervision could have been adhered to,”it says.

“ Communications in general onboard the vessel was hampered by a language barrier between crewmembers,” it says and there was a dispute over the number of crew on board during the trip.

The MCIB says it “appears to be the more probable case on the basis of the evidence available” that the crew comprised five and the skipper on the trip in question, and not the normal crew of six and the skipper.

“One man less in the crew complement can of course increase the fatigue factor and also increase the workload on the remaining crew,” the report says

“In addition, there is the issues as to appropriate manning for particular operations. The Working Time Regulation records provided raise some issues as to how many of the crew were working on the operation of deploying and recovering the nets on the day in question,”it says.

“Given the experience of the crew, the nature of the operations and the nature of the trip, a crew of six and a skipper would have been more appropriate on the vessel,” it says.

Once the incident occurred, given the seriousness of the injury, the skipper should have contacted Medico Cork through the Coast Guard Radio Station for advice and arranged safe evacuation to the hospital, but this did not occur, it says.

“ The owners and operators of the vessel did not comply with a variety of legislation in place governing operations and safety of the crew of an Irish registered fishing vessel,”it says.

“It has not been possible to determine definitively who was the employer of the casualty or the other crew members at the time, given the lack of documentation,”it says, and there is an issue with determining the owner.

“ It is essential on any fishing vessel to have clarity on ownership and on the employer given that the regulatory regime imposes duties on owners and on employers,”the MCIB says.

The vessel was submitted for decommissioning, and the report makes a number of recommendations addressed to the registered owners, to the Minister for Justice, Minister for Transport and Bord Iascaigh Mhara.

Following a recent MCIB report into a serious deck accident aboard a fishing vessel in Dingle Bay last year, the Department of Transport has published a Marine Notice reminding mariners of the dangers of fishing alone.

The MCIB report explains how a lone fisherman on the 9.9-metre An Portán Óir was shooting lobster pots on Friday 14 October 2022 when his leg became entangled in the pot ropes and he remained trapped until he was rescued around four hours later.

It was established that the lack of a personal locator beacon (PLB) was a contributing factor, and that the fisher’s severe pain experienced in the incident could have been alleviated if he had access to a knife.

In response to the report’s recommendations, the Marine Notice reminds owners and operators of fishing vessels of the dangers associated with fishing alone and of the importance of always wearing an approved personal flotation device/lifejacket and a personal location beacon while on deck. Personal locator beacons should be registered.

In addition, lone fishers are recommended to have a suitably protected knife on their person while on deck during fishing operations, especially during potting operations. Knives may also be secured at strategic locations on deck to be available quickly in case of entanglement.

Lone fishers are recommended to carry out a personal risk assessment before each voyage, to remind themselves of the potential risks and to take mitigation measures as required.

More information can be found in Marine Notice No 71 of 2023, attached below.

A recent Marine Notice from the Department of Transport draws attention to the recent report by the Marine Casualty Investigation Board (MCIB) on an incident involving a fishing vessel in Dingle last year.

As previously reported on Afloat.ie, it was found that an incorrectly designed electrical system on the French-registered FV Bikain was the main cause of a serious collision with a pontoon in Dingle Harbour which caused extensive damage on 25 November 2022.

It was established that the design of the electrical system necessitated that emergency batteries were required to be in use at all times for the operation of the vessel, but emergency batteries should only be used for emergency situations when the main power supply fails.

The MCIB has made the following recommendations to owners:

  • A list of critical systems should be carried onboard vessels with a maintenance and testing schedule included for each critical system or piece of equipment.
  • Records of test and maintenance should be retained onboard.
  • Sufficient spares should be carried onboard to enable repair of a vessel’s critical systems in the event of failure.
  • Any failure of critical systems should be reported immediately, and a thorough investigation carried out to identify the root cause.

There are two very specific points in the annual report of the Marine Casualty Investigation Board for last year (2022), which, in pursuance of maritime safety, should be heeded by the sectors involved – watersports and the fishing industry.

The Chairperson of the Board, Claire Callanan, recalls the recommendations made in the 2021 report about incidents associated with water sports and water recreational activities and says: “The MCIB urges those bodies to whom recommendations have been addressed in these recent reports to take steps to improve much-needed safety regimes..”

On the fishing industry, she says: “It is clear that many incidents on fishing vessels are not reported to the MCIB as required by legislation.”

 Marine Casualty Investigation Board Chairperson Claire Callanan Marine Casualty Investigation Board Chairperson Claire Callanan

These are strong comments on the sectors concerned.

“In the MCIB Annual Reports for 2020 and for 2021 we reported on incidents associated with water sports and water recreational activities. We focussed on the recommendations for organisations (especially clubs and commercial entities) aimed at improving their safety standards. In February 2023 we published a report following a lengthy investigation into a tragic fatality that focussed on the safety regime in kayaking in third-level institutions.”

The Chairperson says that the MCIB has made extensive recommendations to the Minister, to Water Safety Ireland and to Canoeing Ireland and Sport Ireland, including:

  • That Canoeing Ireland, in conjunction with Sport Ireland, should consider the establishment, and promotion of a register of Canoeing Ireland qualified instructors with their qualifications that would be available to the public.
    • That Canoeing Ireland, in conjunction with Sport Ireland, should consider the establishment of a scheme for the audit of the safety policies and practices of entities affiliated with this national governing body.
    • That Water Safety Ireland should consider actions to further promote both public awareness of kayaking safety and measures to prevent kayaking accidents

On the fishing industry, Ms.Callanan comments: “ It is clear that many incidents on fishing vessels are not reported to the MCIB as required by legislation. Even from the limited information available to the MCIB from Coast Guard situation reports it appears that many incidents could have been avoided by safety assessment and planning and by proper training of crew.

As noted in MCIB Report No. 302/2022, the Maritime Safety Strategy identified that the fishing vessel sector accounts for a significant proportion of all maritime fatalities and that fishing vessels less than 15 metres (m) in length make up 90% of the Irish fishing fleet in numbers. Fishing vessel safety, particularly in relation to small and medium fishing vessels, is a particular concern. Among the key factors contributing to the loss of life in the fishing sector is working alone and fatigue.”

An incorrectly designed electrical system on a French-registered fishing vessel has been identified as the main cause of a serious collision with a pontoon in Dingle Harbour which caused extensive damage last November.

The Marine Casualty Investigation Board (MCIB) has recommended that the French authorities should test and verify the automatic operation of emergency electrical systems during surveys of fishing vessels following its inquiry into the incident.

The incident occurred on November 25th, 2022 in Dingle Harbour, Co Kerry when the French-registered fishing vessel named Bikain was preparing to go to sea to resume fishing.

The marine casualty caused “serious damages to the pontoons and the support piles and serious damages to boats moored on the pontoons at the time”, the MCIB says. There were no injuries reported.

The vessel was crewed by a Spanish skipper and Spanish crew, and the skipper had extensive experience and had been sailing on fishing vessels since he went to sea around 41 years ago, it says.

“serious damages to the pontoons and the support piles and serious damages to boats moored on the pontoons at the time”

Senior crew also had Spanish certificates endorsed for sailing on French-flagged vessels and were all suitably experienced for this type of vessel, it says.

The vessel had been fishing off the west coast of Ireland and had come into Dingle Fishery harbour centre on 23rd November 2022, due to forecasted bad weather, it says.

As it prepared to leave two days later, the main engine was started, and checks for sailing were being carried out when the controllable pitch propellers (CPP) went to the full astern position.

“ The Skipper tried to stop the main engine with the emergency stop button on the wheelhouse console, but this failed,” the MCIB says.

“ The mooring ropes holding the vessel parted, and the vessel went quickly astern and made heavy contact with the southern boat marina pontoon causing extensive damage to the pontoon and to several boats that were secured there at the time,” it says.

“ The main engine was eventually stopped by shutting off the fuel, and the vessel drifted across the harbour basin,” it says.

“The FV Danny Finn cast off from the western side of the pier and rushed to assist by going alongside the FV Bikain and connecting ropes to assist the vessel and tow her back to the main quay wall where she was then tied up safely,” it says.

The Dingle harbour master activated the port emergency response plan to secure the drifting and damaged boats and pontoon sections.

Divers were mobilised, as well as boats, to tow the damaged boats and secure them to safer moorings. A clean-up operation was also carried out to collect debris from damaged boats, and some were lifted out to the slipway, the report says.

“There were no injuries and no pollution, but extensive damage was caused to the southern pontoon and moored boats,” it says.

“ As this was a French-flagged vessel, the Director of the Bureau d’enquêtes sur les événements de mer (BEAmer) (French Marine Casualties Investigation Office of the Ministry of the Sea) also decided to investigate jointly,” it says.

The report, which makes a number of recommendations, concludes that the electrical system was incorrectly designed on this vessel, and this was the root cause of the casualty.

“ The design of this system necessitated that the emergency batteries were required to be in use at all times for the operation of the vessel, but the emergency batteries should only be used for emergency situations when the main power supply fails,” it says.

“Previous failure of the charging system was not identified as a critical failure and should have instigated a full investigation to identify why these failures were occurring. This investigation should have identified the design faults and prevented this casualty event,” it says.

The MCIB also notes that there were no written procedures for the test and maintenance of “this critical system onboard the vessel”.

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.
