ILV Granuaile


Granuaile Bow HaulbowlineAn advanced multifunctional vessel

Our aids to navigation vessel, ILV Granuaile, delivered in January 2000, was one of the most advanced vessels of its type in the world at the time.

It was a prototype for new builds for Trinity House (England & Wales), the Northern Lighthouse Board (Scotland) and the Middle East Navigation Aids Service (MENAS).

The ILV Granuaile is a multifunctional vessel which can operate in difficult sea conditions. Fitted with Class I dynamic positioning linked to the satellite-based navigation system DGPS, the vessel's primary function is to place and service our 150 offshore buoys, which warn mariners of the location of sand banks, reefs and other offshore hazards near shipping routes.

The vessel also serves as a helicopter platform for servicing offshore lighthouses and is available to assist State agencies with search & rescue, emergency towing, oil pollution control, surveying and offshore data collection.

The ILV Granuaile is available for hire.  For details, go to our Commercial Services page.
