As previously reported on Afloat, Cammell Laird, the Merseyside shipbuilder and engineering facility has been kept busy with dry-docking a range of ships among them the Commissioners of Irish Lights vessel ILV Granuaile, writes Jehan Ashmore.

The aids to navigation vessel built in 2000, mainly serves in the deployment and recovery of buoys, both inshore & offshore and is used for search and rescue missions, underwent dry-docking at the Birkenhead based facility.

Commenting to Afloat on the dry-docking, Irish Lights said, following a competitive tender process to ensure value for money, ILV Granuaile completed an Intermediate drydock in Cammell Laird during January.

As per SOLAS and Flag State requirements, all merchant vessels require a complete survey of the hull (Special drydock) every five years and an Intermediate survey mid-way in the intervening period. These dry-dockings, include maintenance of the hull, thrusters, anodes, cooling inlets and other parts which are immersed in water and normally inaccessible.

All planned work was delivered and the ship has now returned to regular duties of maintaining lighthouses, buoys and beacons around the coast of Ireland.

Afloat adds ILV Granuaile is currently working in waters off northern Donegal having departed Dun Laoghaire Harbour in recent days.
