Waterways Ireland has agreed a three-year contract with ICT company Northgate to manage its IT operations across Ireland.
Northgate will upgrade all computing equipment and servers belonging to the cross-border body which manages, maintains and develops Ireland's navigable waterways.
The work will include the roll-out of a major programme when Waterways Ireland moves to its new head office in Enniskillen.
As part of the contract, a Northgate engineer will be permanently based on site.
Brian Cleland, head of IT in Waterways Ireland, said the contract would enable staff to make more effective use of their time.
"The inland waterways of Ireland offer a wealth of recreational opportunities to a wide range of people and our resources are focused on the management, maintenance, development and restoration of these important amenities," he said.
"Technology is key to the delivery of a seamless service to our many stakeholders - so it is critical we work closely with a company that can provide us with the systems and support necessary to help us work to maximum efficiency."
James Turnbull, managing director of Northgate Infrastructure Solutions, said: "Reliability, cost reduction, flexibility and improved customer service are the main benefits of a managed service to any organisation.
"We are delighted to be working with Waterways Ireland and to be helping them deliver a first class product and service which will be of benefit to all their customers in the island of Ireland."
