#SeaPower - The University of Limerick (UL) has unveiled a unique €2 million underwater robot adapted to inspect, repair and maintain marine renewable energy (MRE) facilities.

Funded by Science Foundation Ireland (SFI) through its Research Infrastructure Programme, the ROV Étaín can operate in challenging wind, wave, and tidal conditions.

Speaking at the launch of the robot at Limerick city docks yesterday (Thursday 26 April), Minister of State Pat Breen said: “Internationally, the offshore renewable energy sector is set to rapidly grow which will help to reduce carbon emissions and arrest climate change. 

“Ireland has the best wind and wave resources in Europe and it is vital that as an island nation we invest and engage in research in the area of marine energy technology. Therefore, I'm delighted to today launch this ROV which will support Ireland's growing offshore renewable energy sector.”

Researchers at UL’s Centre for Robotics and Intelligence Systems (CRIS) have enhanced a commercially available ROV system (Forum Energy Technology’s Comanche ROV) with UL-developed advanced control software (OceanRings), precision navigation and flight control, state-of-the-art robotic imaging and sonar systems and fully automated manipulator systems.

These advanced features allow the robot to operate in the challenging environment of ocean renewable energy to support inspection, repair and maintenance operations.

Prof Daniel Toal, director of the Centre for Robotics and Intelligence Systems at UL, explained why the ROV Étaín was developed. 

“Operation support in the MRE sector usually occurs on floating infrastructures so conditions are regularly beyond the capability and operating limits of commercial ROV technology. This means new smart ROV systems capability is necessary and that is what our team at UL has developed and launched today.”

UL’s Centre for Robotics and Intelligence Systems is part of the University College Cork-led SFI national Centre for Marine and Renewable Energy Ireland (MaREI).

The MaREI robotics lab at UL leads operations support engineering projects with industry partners such as Shannon Foynes Port Company, ESB, Ireland’s National Space Centre, SonarSim, Teledyne, Resolve Marine, CIL, IDS Monitoring and among others.

“The advanced robotics technology developed at UL will be crucial in supporting the burgeoning marine renewable energy sector,” said UL president Dr Des Fitzgerald. “It will also play a significant role in reducing the cost of installing and maintaining large-scale offshore energy generation infrastructure. 

“As the worldwide marine renewable energy sector grows, UL's research contribution in this area will have even greater impact. I am particularly happy to see this advanced UL technology being developed, trialled and launched in Limerick city docks. 

“The UL robotics base at the docks is just one of our commitments to grow and maintain strong links between the campus and the heart of Limerick city, with strategic partners like Shannon Foynes Port Company.”

Speaking about the project, Dr Ciarán Seoighe, deputy director general of Science Foundation Ireland, said the new ROV “will enhance our understanding of subsea exploration and marine renewable energy, placing Ireland at the forefront of advances in environmental research that are crucial to our country's future.”

Ireland's Trading Ketch Ilen

The Ilen is the last of Ireland’s traditional wooden sailing ships.

Designed by Limerick man Conor O’Brien and built in Baltimore in 1926, she was delivered by Munster men to the Falkland Islands where she served valiantly for seventy years, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties.

Returned now to Ireland and given a new breath of life, Ilen may be described as the last of Ireland’s timber-built ocean-going sailing ships, yet at a mere 56ft, it is capable of visiting most of the small harbours of Ireland.

Wooden Sailing Ship Ilen FAQs

The Ilen is the last of Ireland’s traditional wooden sailing ships.

The Ilen was designed by Conor O’Brien, the first Irish man to circumnavigate the world.

Ilen is named for the West Cork River which flows to the sea at Baltimore, her home port.

The Ilen was built by Baltimore Sea Fisheries School, West Cork in 1926. Tom Moynihan was foreman.

Ilen's wood construction is of oak ribs and planks of larch.

As-built initially, she is 56 feet in length overall with a beam of 14 feet and a displacement of 45 tonnes.

Conor O’Brien set sail in August 1926 with two Cadogan cousins from Cape Clear in West Cork, arriving at Port Stanley in January 1927 and handed it over to the new owners.

The Ilen was delivered to the Falkland Islands Company, in exchange for £1,500.

Ilen served for over 70 years as a cargo ship and a ferry in the Falkland Islands, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties. She stayed in service until the early 1990s.

Limerick sailor Gary McMahon and his team located Ilen. MacMahon started looking for her in 1996 and went out to the Falklands and struck a deal with the owner to bring her back to Ireland.

After a lifetime of hard work in the Falklands, Ilen required a ground-up rebuild.

A Russian cargo ship transported her back on a 12,000-mile trip from the Southern Oceans to Dublin. The Ilen was discharged at the Port of Dublin 1997, after an absence from Ireland of 70 years.

It was a collaboration between the Ilen Project in Limerick and Hegarty’s Boatyard in Old Court, near Skibbereen. Much of the heavy lifting, of frames, planking, deadwood & backbone, knees, floors, shelves and stringers, deck beams, and carlins, was done in Hegarty’s. The generally lighter work of preparing sole, bulkheads, deck‐houses fixed furniture, fixtures & fittings, deck fittings, machinery, systems, tanks, spar making and rigging is being done at the Ilen boat building school in Limerick.

Ten years. The boat was much the worse for wear when it returned to West Cork in May 1998, and it remained dormant for ten years before the start of a decade-long restoration.

Ilen now serves as a community floating classroom and cargo vessel – visiting 23 ports in 2019 and making a transatlantic crossing to Greenland as part of a relationship-building project to link youth in Limerick City with youth in Nuuk, west Greenland.

At a mere 56ft, Ilen is capable of visiting most of the small harbours of Ireland.
