This year will be Belfast's busiest for cruise ships, with more than 145,000 passengers set to visit - up 25% on 2015.
Belfast Harbour will play host to 81 cruise ships over the next 12 months, carrying passengers from around the world.
The harbour is also in the process of building a new £1m cruise ship terminal.
The delayed project has been earmarked for a site at Airport Road West, planning documents have shown.
It was originally planned to be close to Titanic Belfast, one of the region's top tourist attractions.
A spokesperson for Belfast Harbour said: "In recent years cruise lines operating on western European itineraries have introduced larger and longer vessels which require deeper channels and additional quay space.
"To accommodate these next-generation cruise ships, and the increased popularity of Belfast, Belfast Harbour plans to develop a new cruise berth at D3, near the RSPB nature reserve on the Co Down side of the port.
"This £14m project, developed following positive feedback from cruise line operators and excursion providers, will enhance passengers' experience of Belfast and further support the city's popularity as a cruise destination."
Joe O'Neill, Belfast Harbour's commercial director, told how the port had "almost doubled the number of cruise ships calling into Belfast, which is a major achievement".
It is the "huge popularity of world-class attractions" that has helped bring in visitors from across the world, according to Gerry Lennon, chief executive of Visit Belfast, who added that having the right infrastructure was crucial.
