#NewDesign - A new catamaran designed for servicing offshore drilling and energy platforms could help work crews get to where they're needed safety in some of the roughest seas.

Wired's Autopia blog reports on the SHC Wavedancer, a proposed catamaran with a submersible hull that could literally cut through and dissipate potentially dangerous waves - keeping the vessel stable enough in swells of up to 15 feet so that delicate operations, such as work on oil pipelines or wind turbines, can proceed without delay.

The new design is the work of veteran energy installation and construction consultant Dennis Knox, who is looking to crowdfunding to finance the first stages of the project.

#BelfastWindTerminal - A new £50m offshore wind terminal which has been completed in Belfast Harbour, has been handed over to DONG Energy and ScottishPower Renewables.

As previously reported on Afloat.ie, the terminal, the first purpose-built offshore wind installation and pre-assembly harbour in the UK or Ireland, will be used as a hub to help service a market valued in excess of 100bn. Up to 300 jobs are expected to be created, ranging from welders to electricians and engineers.

The official hand-over was attended by Northern Ireland's First and Deputy First Ministers, Peter Robinson MLA and Martin McGuinness MLA, along with Len O Hagan, Belfast Harbour's Chairman and Brent Cheshire, DONG Energys UK Country Chairman.

DONG Energy has signed a lease for the terminal which will be used initially to support the development of the West of Duddon Sands Wind farm in the Irish Sea, a joint venture between ScottishPower Renewables and DONG Energy. Work on the wind farm has already started and Belfast Harbour has received its first shipment of wind farm components. Its anticipated that the first turbines will depart Belfast this summer for erection at the site.

Welcoming the handover, Len OHagan, Belfast Harbour's Chairman, said: "Delivering this immense project on time and on budget has been a major achievement. This is a historic development for Belfast which has the potential to usher in a major new industry for Northern Ireland a development which is all the more poignant given that this is the Harbours 400th anniversary year".

He added "Over the years the harbour has helped bring other industries to Belfast such as shipbuilding and aerospace by investing heavily in infrastructure and land reclamation. This is a continuation of that strategy and a demonstration of our long-term commitment to enhance the local economy".

The 50-acre terminal, located on the Co. Down side of the port, is the largest single investment in Belfast Harbours 400-year history. Built by local construction company Farrans, the project took 15-months, 750,000 man hours, one million tonnes of stones and 30,000 tonnes of concrete to complete.

The 200,000 m2 facility, large enough to accommodate 30 football pitches, includes a 480m deep-water quayside. Up to three vessels will be able to berth simultaneously with access available around the clock.

Brent Cheshire, DONG Energys UK Country Chairman commented: "Having a bespoke facility at our fingertips will help us plan our offshore construction very effectively and help with our work to lower the cost of offshore wind farms. The site is in an excellent strategic position for DONG Energy as we have several wind farms under development in the Irish Sea. This is a port that can handle the large number of huge pieces of equipment required".

Keith Anderson, ScottishPower Renewables CEO, added: "The facility at Belfast Harbour is one of the most advanced anywhere in the world for the assembly of offshore wind turbines, and we are delighted to be taking over the lease as we start offshore construction on the West of Duddon Sands project.

This marks a significant milestone for the West of Duddon Sands project, and we are sure that Belfast will play a hugely important role in its successful delivery. The investment in Belfast Harbour will ensure that the city has a long-term future as a leader in renewable energy.

Over 100 turbines, each with a rotor diameter of 120m, will be shipped from the new terminal to the West of Duddon Sands project. It will be one of the worlds largest offshore wind farms when it is commissioned in 2014.

The UK is Europes leading offshore wind generator and has plans to develop 11,000 new offshore wind turbines, a quarter of which are expected to be built within 150 nautical miles of Belfast. It is anticipated that 32 gigawatts of electricity, one quarter of the nations electricity needs, will be provided by offshore wind.

#POWER FROM THE SEA - Marine-based renewable energy projects could be introduced without a damaging impact on marine wildlife, according to a new briefing paper from Friends of the Earth.

Business Green reports on the paper from the environmental campaign group, written by marine ecologist Martin Attrill of Plymouth University's Marine Institute, which draws together research on the biodiversity impact of offshore wave energy, tidal energy and wind power schemes.

Attrill found that the deployment of sea energy arrays could ultimately benefit many marine species by reducing the effects of fishing activity, and even acting as reefs to attract new sea life.

He cites the example of a grey seal colony in Strangford Lough that has steered clear of a nearby tidal turbine over the three years of its operation in the lough.

However, Business Green says the report makes clear that the deployment of such projects "must be done sensitively", noting that any negative impact on biodiversity "would be significantly lower than the damage done to marine wildlife by rising sea levels caused by climate change".

#POWER FROM THE SEA - Conor Haughey is seeking €3 million investment in new wave power technology inspired by his father's attempts at making his private island self-sufficient, as the Sunday Independent reports.

Haughey, son of former Taoiseach Charles Haughey, says his company Blue Power has developed a new way of capturing energy from ocean waves - and that tests at UCC's Hydraulic Marine Research Centre have concluded the technology is superior to many existing products in the sector.

He said: "We thought, how can we harness the power of the ocean on our doorstep? We have the best waves in the whole world. The west coast of Ireland is a huge untapped resource."

The company is now looking for angel investors or a utility parter to develop the technology for commercial use.

Engineer Colin O'Brien, who will be desiging Blue Power's prototypes, commented: "The whole west coast of Ireland has incredible waves. We could be the Saudi Arabia of renewable energy."

#OCEAN ENERGY – As previously reported the fourth International Conference on Ocean Energy (ICOE) which concludes tomorrow at the Convention Centre Dublin, is where an Irish Lights buoy has been deployed facing the venue's prime river frontage, writes Jehan Ashmore.

After previous ICOE conferences held in Brest and Bilbao, Sustainable Energy Authority of Ireland (SEAI) and partners European Ocean Energy Association's (EU-OEA) have brought the internationally important conference to the Irish capital. A notable feature to mark the three-day conference is the buoy, which is a Type 2 Port Laternal Marker, only one of two such buoys within the inventory of the Commissioners of Irish Lights.

It is fitted with a variety of meteorological and oceanographic sensors which will be tweeting data automatically via the automatic identification system (AIS), giving a unique insight into weather conditions outside the convention centre.

#POWER FROM THE SEA - The fourth International Conference on Ocean Energy (ICOE) begins tomorrow Wednesday 17 October at the Convention Centre in Dublin's Docklands.

Over 750 international experts and world-leading companies in ocean energy will gather in Ireland’s capital city for the three-day conference, hosted by the Sustainable Energy Authority of Ireland (SEAI) in association with the European Ocean Energy Association.

Global industry and academic experts in marine renewable energy will present over a hundred papers on themes important to growing this new marine sector.

The conference also provides an opportunity for a trade exhibition where many of the top industrial players will demonstrate the latest technologies in harnessing renewable energy from the sea.

The International Conference on Ocean Energy is the global marine energy event focused on the industrial development of renewable marine energy. Held every two years, the goal of the conference and exhibition is to share recent experiences from research and demonstration efforts.

It aims to accelerate development by stimulating collaboration networks between companies and research and development centres. It also specifically targets engagement of the experience of operators in related marine and power industry sectors.

#MARINE SCIENCE - Apart from some of the world's largest concentrations of wave energy, the waters of Galway Bay and the west coast of Ireland are now providing something potentially even more valuable - information.

That's according to IBM's Harry Kolar writing for the blog A Smarter Planet, as he discusses the start of his company's new underwater data collection project developed in association with the Sustainable Energy Authority of Ireland (SEAI) and the Marine Institute.

As previously reported on Afloat.ie, the system comprises an array of noise sensing equipment such as hydrophones deployed in Galway Bay to monitor the noise levels produced by wave energy conversion devices in real time.

This array is attached to a large monitoring buoy about 2km from the southern shore, and constantly transmits the data it records to a receiving system on land.

The scheme, which was finally switched on last month, is an offshoot of the SmartBay initiative for developing and testing new marine technology to foster future commercial development in the fast-growing marine science sector. The 'Twitter buoy' deployed for the Volvo Ocean Race finale recently is another of the project's schemes.

"Initially, the system will capture and analyse the ambient noise of the ocean to establish a baseline of acoustics including natural and anthropogenic (man-made) sound sources including vessel traffic," writes Kolar.

"But the ultimate goal is to capture and analyse the sounds and vibrations of hulking wave energy conversion machines that have begun bobbing along off the coast and help determine what, if any impact the sound waves from those devices could have on marine life – but especially highly sensitive dolphin, porpoise, and whale populations."

#POWER FROM THE SEA - Martin McAdam of Aquamarine Power talks to The Irish Times about his company's efforts to harness power from the sea.

The Edinburgh-based firm has spent a number of years and some £60 million (€74.5 million) developing its sea surface instruments - using technology researched at Queen's University Belfast - at locations in Scotland, Northern Ireland and the United States.

Most recently, the business has been overseeing the final stages of an underwater base off Orkney to complete testing of its latest wave energy 'harvester' prototype, the Oyster 800.

As previously reported on Afloat.ie, the Oyster 800 can generate an incredible 800 kilowatts by way of a giant hinged flap that juts out of the water.

Each passing wave closes the flap shut like a clamshell, with the resultant hydraulic pressure driving an onshore turbine.

It marks an impressive development, but as McAdam says, the wave energy sector still requires patience from those who provide its funding.

“We need to perfect the technology that we have got," says the Aquamarine chief executive, who adds that the objective is “not revolution anymore, but evolution”.

“We shouldn’t be overambitious," he says. "We should get the technology to a stage where it is robust and cost effective. In 10 years’ time, if we in Scotland have somewhere up to 500MW, then that would be a successful industry.”

#POWER FROM THE SEA - When will Ireland make the most of its wave energy? That's the question Journal.ie last week posed to experts in the field.

Some studies claim that up to 75% of Ireland's energy needs could be met by the same wave power that's a driving force behind Ireland's growing reputation as a top surfing destination.

But the industry also points out that the "very difficult technology" involved has yet to be perfected.

“It is perfectly possible to design the necessary equipment,” sats Carnegie Wave's Kieran O’Brien. “But it has to be able to withstand force 9 gales.

“We need something in the water that will extract that energy but will still be there when those storms hit."

Development of the sector is a catch-22 situation, as investors are cautious of putting in funds when no one is yet producing grid-connected power at scale, yet obviously such production requires serious capital.

Ireland in particular faces the problem of being what the industry describes as the Saudi Arabia of wave energy, yet having "no short term opportunities for R&D funding".

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.
