#CoastalNotes - The video above is not a coastal distress flare, but a 'fireball' from space burning up as it enters the atmosphere far above Ireland.

A flurry of reports from concerned members of the public received by the Irish Coast Guard have been traced to the meteorite that streaked across the sky on Sunday night (April 26).

The Irish Mirror has more on the spectacular phenomenon that lit up the whole country for a few seconds shortly after 10pm on Sunday.

And as David Moore of Astronomy Ireland says, it was so bright that it's likely part of the space rock survived re-entry and might be found intact somewhere on land or shore.

A extensive rescue search in northeast England was called off on Monday when it was found that the planet Jupiter had been mistaken for a distress flare.
BBC News reports that Tymemouth RNLI lifeboat and an RAF rescue helicopter had been dispatched to search for a possible vessel in distress after a call from a member of the public on Monday evening.
But on establishing further details from the informant "it became apparent that the flares were in fact the planet Jupiter which is very low in the sky at this time of year", said Tynemouth RNLI's Adrian Don.
The RNLI stresses that the false alarm was made with the "best intentions" and urges anyone who thinks they have spotted a vessel in distress to contact emergency services.

Two Mayo fishermen stranded at sea after their boat capsized were not assisted after they used flares, a Marine Casualty Investigation Board (MCIB) report has found.
The report, released earlier this week, recounted that the 33m crabber Léim an Bhradán had set out from Porturlin in Ballina on the morning of Saturday 30 October last on a routine fishing trip to retrieve and reset crab and lobster pots some 12 to 15 miles offshore.
The vessel was manned by skipper John O’Donnell, aged 18 at the time, and crew Nathan Flannery, in his 20s, both young men but with many years of fishing experience between them.
At some time between 1pm and 1.45pm, after having successfully hauled and re-shot one tow of pots, a second tow, in the process of being hauled, was partially aboard being emptied and re-baited.
The vessel was listing slightly to starboard due to the pots being hauled over that side when a large wave broke over the starboard quarter and flooded the working deck.
This caused the vessel to list further to starboard, allowing more water over the side and causing the stacked pots and boxes to shift, increasing the angle of the list and throwing both men into the water before the boat capsized and sank rapidly.
The boat's canister-type liferaft, which was not secured to the vessel but stored in a cradle on top of the wheelhouse, floated to the surface with a life ring. O’Donnell and Flannery managed to inflate the raft and climb aboard around 2pm, after some difficulties in operating the gas inflation cannister and releasing the raft from its securing straps.
The men then opened the SOLAS B equipment pack stored on the liferaft and released two parachute flares, 20 minutes apart, with no response. At around 3pm the pair spotted an Irish Coast Guard helicopter and released an orange smoke signal, but the chopper did not respond. It later transpired that this aircraft was the Sligo-based coastguard helicopter on a training exercise.
Several hours later, the alarm was raised ashore when the Léim an Bhradán had not returned to port. A rescue helicopter and lifeboat were tasked to the scene before midnight and the liferaft was located just after 1.30am.
O’Donnell and Flannery, who had earlier donned thermal suits to protect from the cold, were picked up and brought ashore by the lifeboat. Neither was injured in the incident.
The MCIB report found that had the lifeboat been secured to the vessel, it would have been in a position to inflate correctly as per its design.
It also found that had the EPIRB emergency beacon been mounted to a 'float free' bracket outside the wheelhouse, rather than stored inside, it would have floated to the surface and activated automatically, notifying the coast guard immediately.
Neither skipper nor crew was in possession of the boat's handheld VHF set, the report noted, which hampered their ability to contact any nearby vessels for assistance.

A search coordinated by Belfast Coastguard that was prompted by several reports of sightings of red flares at the mouth of Carlingford Lough was stood down last evening after nothing was found.

The first sightings of the red flares came in at 18.10 via 999 calls from members of the public reporting that they had seen the flares near the mouth of the Lough, southwest of Kilkeel.  Belfast Coastguard issued a relay broadcast to vessels in the area to try and find more information about the potential vessel in distress, and three fishing vessels responded to say that they too had sighted the flares.

Belfast Coastguard then sent the South Down Coastguard Rescue Team, Kilkeel RNLI Inshore Lifeboat and the Irish Coast Guard Helicopter to the scene to begin a search. The three fishing vessels who responded to the initial broadcast also maintained a lookout during this time. The search area was approximately five and a half miles, and three miles offshore, and the search was completed at 20.30 and all resources stood down with nothing found.

Belfast Coastguard Watch Manager Rob Steventon said:

"With good visibility on scene and the search area completely saturated we are satisfied that the red flare sightings were not from a vessel in distress.  All sightings of distress flares reported to the Coastguard have to be thoroughly investigated, however a proportion of these turn out to be either Chinese lanterns, or non distress situations, such as people disposing of out of date flares.  Members of the public should be aware however, that using flares in a non-emergency situation is against the law."

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.
