Belfast Harbour eyes £1.3 billion expansion amid Irish Sea port capacity pressure

Estimated reading time: 3 minutes

Belfast Harbour has unveiled a £1.3 billion investment programme aimed at expanding port capacity, strengthening Irish Sea trade links, and preparing for rising cargo volumes over the next 25 years.

The long term Masterplan, titled Horizons of Opportunity, outlines projects ranging from freight terminal expansion and berth extensions to clean energy infrastructure and maritime training facilities. The Trust Port said the investment is designed to secure Belfast’s role as a major gateway on the Dublin to Belfast Economic Corridor as pressure builds on port infrastructure across Ireland’s east coast.

Ports are often judged by what they prevent rather than what they handle. Delays avoided, cargo flows maintained, and supply chains kept moving quietly in the background. Belfast Harbour’s latest projections suggest that keeping trade moving smoothly may soon require significantly more space and infrastructure.

According to forecasts prepared by Haskoning, annual cargo throughput at Belfast Harbour could rise from around 24 million tonnes today to more than 30 million tonnes by 2050 under steady growth conditions. Under higher growth scenarios, volumes could reach between 40 million and 50 million tonnes.

The port warned that under all scenarios except stagnation or decline, existing infrastructure capacity would eventually come under strain without additional investment.

Among the planned projects are a new freight terminal at West Bank Road created through Belfast’s first land reclamation project in 25 years, redevelopment of Stormont Wharf, and an extension of the container terminal berth to accommodate next generation vessels. The programme also includes the port’s first shore power facilities for docked vessels, a logistics park, a clean energy hub, and a maritime skills academy.

Independent analysis by Ulster University and Grant Thornton estimates that the investments could underpin around £12 billion in annual Gross Value Added linked to trade handled through the port. The programme is also expected to support nearly 5,500 construction jobs during delivery.

Joe O’Neill, chief executive of Belfast Harbour, said the port’s core role remains focused on maintaining the steady movement of essential cargoes into Northern Ireland.

“Much of what people and businesses across Northern Ireland depend on passes through here every day, from food and fuel to construction materials and consumer goods,” he said. “Ensuring that trade continues to flow efficiently is our core purpose.”

The Harbour Estate currently spans around 2,000 acres of land and 1,000 acres of water, giving Belfast a larger development footprint than many competing ports along the Irish east coast.

One of the biggest issues now facing the programme is financing. Belfast Harbour said delivery of the full Masterplan will depend partly on changes to the port’s accounting classification, which would allow it to borrow more flexibly for infrastructure investment.

Dr Theresa Donaldson, chair of Belfast Harbour Commissioners, said collaboration with government and industry stakeholders will be critical.

“For port projects, a key priority remains the reclassification of Belfast Harbour’s accounting status, which would allow us to borrow prudently to fund critical investment,” she said. “Without this change, we can still deliver, but we will face harder choices regarding the pace and scope of our work.”

Northern Ireland Infrastructure Minister Liz Kimmins said her department is working on legislative changes linked to Trust Port reclassification to support the Harbour’s investment ambitions.
