#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".

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
