University of Limerick (UL) has unveiled a unique €2 million underwater robot at the docks in Limerick city. The Remotely Operated Vehicle (ROV) was officially launched by Minister of State Pat Breen TD. The Science Foundation Ireland (SFI) funded ROV Étaín can operate in challenging wind, wave, and tidal conditions and will be used to inspect, repair and maintain Marine Renewable Energy (MRE) facilities.

Offshore renewable energy sector set to rapidly grow


“Internationally, the offshore renewable energy sector is set to rapidly grow which will help to reduce carbon emissions and arrest climate change," Minister Breen said. "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 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. Professor Daniel Toal, director at UL's CRIS, said: “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.” 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).

Support engineering projects with industry partners


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. 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,” UL president Dr Des Fitzgerald said.
