After more than 20 years, United Nations members have agreed on a new framework to protect marine life in international waters, as The Journal reports.

The historic treaty was reached late on Saturday night (4 March) at the UN Headquarters in New York following two weeks of discussions.

It will see the creation of a new body to manage conservation of ocean life as well as establish marine protected areas in the high seas.

The move could be a boon to migratory marine wildlife including whales, dolphins, turtles and fish — protections on which have until now been hindered by a lack of legislative unity across various ocean territories.

The treaty also sets ground rules for conducting environmental impact assessments for commercial activity. “It means all activities planned for the high seas need to be looked at, though not all will go through a full assessment,” said Jessica Battle of the Worldwide Fund for Nature.

President Michael D Higgins has welcomed the treaty as “a gain for the future of humanity”.

He added: “It is essential that attention now swiftly moves to formal adoption of the text, to ratification and to implementation.

“Time is of the essence if the 30x30 pledge made by countries at the UN biodiversity conference in December to protect a third of the sea by 2030 can be reached. A target which must be considered a bare minimum.”

This weekend's 'Foyle Days' in the north-west city is set to welcome two offshore patrol vessels (OPV) the Naval Service LE Emer (P21) and the Royal Navy's HMS Severn (P 283), writes Jehan Ashmore.
The maritime event includes a variety of sailing organisations and accompanying craft to include the 96ft tall-ship schooner Johanna Lucretia. In addition the festival's star visitor attraction will be the inaugural call of the 68ft yacht Derry-Londonderry which is to take part in the Clipper 11-12 Round the World Yacht Race.

On the naval front, LE Emer was built in Cork's Verolme Dockyard in 1978. She represents the oldest of the eight-strong fleet and is designed from the Naval Service's first purpose built patrol vessel OPV LE Deirdre (P20) but was modified to improve her stability and speed. This vessel was decommissioned several years ago and was converted into a private yacht.

The original BOFORS 40mm L60 gun of the LE Emer was recently upgraded to a BOFORS 40mm L70 to improve range and accuracy of her main armament. She alongside her 65m sisters LE Aoife (P22) and LE Aisling (P23) where all built primarily to patrol the Irish section of the European Economic Zone (EEZ).

During their careers the 'Emer' class vessels have also completed numerous re-supply missions to Irish troops serving overseas with the United Nations and in particular in the Lebanon. A crew compliment of 46 (5 officers) operate the vessels which are all now in their fourth decade of service.

OPV HMS Severn is the third of four 'River' class offshore patrol vessels and like her Irish counterpart is deployed on fishery duties. The 1,677 displacement tonnes vessel was built in 2001 in the UK'S south coast port of Southampton at Woolston Docks. Her home port for the 30 crew is at HM Naval Base in neighbouring Portsmouth.

She becomes the fifth ship to bear the name and with sisters HMS Mersey (P 282) and HMS Tyne (P 281) they are assigned to the Fishery Protection Squadron. Click the ship's diary to follow the ship news. The final member of the River class HMS Clyde (P 257) serves as a Falklands Islands Patrol Vessel (FIPV).

Taking my grandson to school in Crosshaven he showed me a page of homework which his teacher had said they would be talking about in class. It demonstrated the effect of debris on the oceans and what can happen when litter is thrown into a river or stream or left on the beach.

It was very topical, because this week the Fifth International Marine Debris Conference is taking place in Hawaii, organised jointly by the National Oceanic and Atmospheric Administration and the United Nations Environment Programme. This is an attempt to deal with the increasing problem of debris in the oceans of the world.

A United Nations report revealed some pretty frightening facts to the conference. Just two kinds of rubbish make up more than half the marine debris in the world. One is predictable enough – the horror of plastic choking sea life. The other came as more of a shock. The second most abundant kind of marine litter is smoking-related. Cigarette butts and packing account for nearly half of all sea rubbish in some parts of the world, according to the UN.

About 40 per cent of the litter in the Mediterranean Sea comes from this source. In Ecuador, smoking-related refuse accounted for more than half of coastal rubbish.

Ocean debris is a severe threat to the marine eco system. It kills at least 1 million sea birds and 100, 000 mammals each year, according to the United States National Oceanic and Atmospheric Association. The general prognosis at the conference in Hawaii has been pretty grim. Things are getting worse and it is the fault of humans on land using the oceans as rubbish dumps.

As my grandson's homework showed, it takes two weeks for a bit of fruit thrown into a river or the sea to bio-degrade. It will be two months before a piece of cardboard breaks down, three months for a milk carton and matters get worse where a cigarette butt is concerned. That will take ten years to disintegrate, a Styrofoam coffee cup 50 years, a plastic bag over a hundred and the six-pack ring so often tossed overboard from boats 400 years, with the plastic bottle even worse at 450 years.

The threat and impact of marine debris have long been ignored. Perhaps it is the perceived vastness of the ocean and lack of visibility of marine debris, but the teachers in Crosshaven national school, on the edge of Cork Harbour deserve praise for making their young pupils aware of what throwing litter into a river or dumping it on a beach does.

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.
