Marine Minister Timmy Dooley has visited the Irish Lights vessel ILV Granuaile during its annual programme of aids to navigation maintenance on the Shannon Estuary.
The visit provided an opportunity to see at first hand the specialist work undertaken by Irish Lights to maintain one of Ireland's busiest and most strategically important shipping routes.
Minister Dooley was welcomed aboard by Irish Lights chief executive Yvonne Shields O'Connor and Granuaile master Captain Mike Murphy, who outlined the vessel's capabilities and the annual maintenance programme for buoys and other navigational aids.
During the visit, the minister met officers and crew and received briefings on the vessel's roles in heavy-lift buoy operations, emergency wreck marking, search and rescue support and MetOcean monitoring.
"Having visited the ILV Granuaile earlier this week, I saw first-hand how Irish Lights delivers on its core mission of safe navigation for all," Minister Dooley said.
"The work being carried out on the Shannon Estuary shows the importance of maintaining a resilient and technically advanced aids to navigation service — one that protects lives at sea, supports the flow of trade and economic activity, and safeguards our marine environment."
He praised the professionalism and expertise of Irish Lights personnel in maintaining safe passage through some of Ireland's most challenging waters.
The Shannon Estuary handles more than one-fifth of the fuel and raw materials used in Ireland's electricity generation while also serving as a deepwater gateway for agricultural and energy imports.
Irish Lights maintains the statutory buoyage system marking the estuary's narrow navigation channel together with leading lights at Corlis Point, helping vessels negotiate strong tidal streams and shifting shoals.
As part of the maintenance programme, Granuaile lifts navigation buoys completely clear of the water using its heavy-duty cranes for inspection and servicing. Crews remove marine growth, inspect mooring chains, carry out structural repairs and install upgraded LED lanterns, batteries and electronic navigation equipment, including AIS transmitters and radar beacons.
The minister also received an update on forthcoming offshore work servicing the K4 and K5 North Atlantic weather buoys. Operating between 90 and 290 nautical miles offshore in waters more than 1,000 metres deep, these stations provide vital meteorological and oceanographic data used by Met Éireann and the UK Met Office for weather forecasting and storm warnings.
Irish Lights chief executive Yvonne Shields O'Connor said the Shannon Estuary required detailed planning and close coordination between marine and shore-based teams.
"We were delighted to welcome Minister Dooley aboard and to showcase the expertise that underpins safe navigation around Ireland's coast," she said.
