An Evac Evolution ballast water management system (BWMS) will be installed on the 'ILV Granuaile', an aids to navigation vessel operated by the Commissioners of Irish Lights.

The vessel’s primary function is to place and service 150 offshore buoys. The vessel also provides support for the teams tasked with maintaining a further 65 lighthouses and beacons around the coast of Ireland and Northern Ireland. In addition, the ship supports the national response to maritime wreck and new dangers to navigation.

With a length of 79.69m, the ship is equipped with advanced DP equipment and accommodates a crew of 16.

“We are delighted to have won the BWMS order for a vessel which has such an important role in maintaining safety at sea and protecting the marine environment”, said Adam Rogers, Evac’s Head of BWMS Global Sales.

The vessel will be equipped with an Evac Evolution system with the capacity to treat ballast water at a rate of up to 250m3/hr. The components will be supplied in modular form enabling them to be distributed to make the best use of available space within the engine room.

The Evac Evolution attained IMO and USCG Approval in 2019. Based on a combination of filtration and UV technology, the space-saving system is energy effective and chemical-free. It has a ‘feedback loop’ which uses UV transmission as the parameter for precisely determining UV dosage. This ensures effectiveness in challenging water conditions, but saves on power during normal running. Effective in fresh, brackish and seawater, the Evac Evolution system is available with capacities from 34m3/hr to 1,500m3/hr in a single unit. It can be supplied in modular form for retrofits or skid mounted for newbuild applications.
