Port statistics In 2020 Liverpool was the United Kingdom's fourth largest port by tonnage of freight, handling 31.1 million tonnes. Marina Liverpool Marina is in Coburg Dock and has 340 berths. Cruise terminal Cruise ships once sailed from Langton Dock, part of the enclosed north docks system. Departures and arrivals were subject to tides. Cruise ships returned to Liverpool's Pier Head in 2008, berthing at a newly constructed cruise terminal, enabling departures and arrivals at any time. Until 2012, any cruises beginning in Liverpool still departed from Langton Dock but, since 2012, the terminal has been used as the start and end of voyages, and not merely a stop-off point. This led to a dispute with Southampton due to the large public subsidy provided for the new terminal, which Liverpool City Council has agreed to repay. Ships which have called at Liverpool Cruise Terminal include Queen Elizabeth 2 (QE2), Grand Princess, Caribbean Princess and RMS Queen Mary 2. A number of large Royal Navy vessels, such as and , have also visited the terminal.

The terminal was accessed via the Wapping Tunnel from Edge Hill rail junction in the east of the city. The station was demolished in 1972. The tunnel is still intact. Until 1971, Liverpool Riverside railway station served the liner terminal at the Pier Head. Today, for passengers disembarking from the new cruise terminal, city centre circular buses call at the terminal directly, while Moorfields and James Street are the nearest Merseyrail stations.
