The investment forms part of a wider £300 million development strategy for the harbour.

Construction is set to begin this week, with the first phase focusing on a dual-purpose quay and deep water berth. Scheduled for completion in 2027, the new terminal will be capable of accommodating some of the world’s largest cruise vessels.

A second phase, which will support the infrastructure for the offshore wind energy industry, is expected to be completed by 2030.

Joe O’Niell, chief executive of Belfast Harbour, emphasised the strategic importance of the project, particularly in increasing “turnaround” cruise calls – where one group of passengers disembarks and another boards on the same day. “This will have a multiplier effect on visitor numbers, increasing associated bed nights while growing the positive economic impact for the region,” he said.

The new facility is expected to strengthen Belfast’s position as a key destination on the cruise circuit while also positioning the port as a hub for renewable energy logistics and development.

Graham, based in County Down, is Northern Ireland’s largest construction firm and is already engaged in major developments across the city, including the Loft Lines apartment complex at the harbour and the new headquarters for tech firm Kainos in the city centre.

The port expansion represents a major step in Belfast’s ongoing regeneration and economic growth, aligning with wider goals for sustainability, tourism, and infrastructure modernisation.
